The time series of clear-sky ocean brightness temperatures (BTs) and derived SSTs were found to be unstable. While the SSTs were empirically stabilized against in situ SSTs, the measured BTs were left intact. To better understand the AVHRR calibration and stabilize its BTs, the Sensor Stability for SST (3S) system was established at NOAA, which monitors orbital statistics of the sensor measured blackbody temperatures (BBTs), blackbody counts (BCs), and the space counts (SCs), along with the derived calibration gains and offsets. Other factors affecting the calibration are also monitored, including the Sun and Moon position relative to the sensor, local equator crossing time, and duration of the satellite night. All AVHRRs show long-term and band-specific smooth changes in the calibration gains and offsets, which are occasionally perturbed by spurious non-monotonic anomalies. We argue that the operational quality control (QC) and calibration procedures are suboptimal and should be improved. More stringent QC should be applied, and scan lines with bad calibration should be filled in by interpolation from the best parts of orbit or satellite lifetime. Work is underway to redesign the AVHRR QC and calibration algorithms, reprocess L1b, and use in the subsequent ACSPO SST RANs.

The 3.75 um band of VIIRS provides imagery in high spatial resolution (similar to 375 m) twice a day and can be used to monitor temperature variation of hot spots due to industrial activities. The 3.9 um channel of AHI imagery in 10-minute time resolution enables continuous monitoring of temporal variation of urban heat island temperature. This paper compared using imageries of VIIRS and AHI MWIR channel to monitor both spatial distribution and temporal (seasonal and diurnal) variation of hot spots and urban heat islands. It was shown that the MWIR imageries of VIIRS and AHI complement each other in understanding the spatial structure and temporal variation of social economic activities-related heat sources.

The algorithm is based on estimating the degree of coherence of the received GNSS reflected waveform or Delay-Doppler Map (DDM). While at open ocean conditions, the scattered signal follows the diffuse scattering model, over flat sea ice it follows the coherent scattering model. In order to measure the degree of coherence of the received waveform or DDM, a correlation with the clean Woodward Ambiguity Function (WAF) is performed. The more similar the received signal is to the WAF, the more coherent is the scattering, and consequently, the more likely a flat sea ice surface is involved. In order to assess the performance of the proposed estimator a probabilistic study based on a Bayesian approach is performed, using the OSISAF Sea Ice Concentration (SIC) maps as ground truth. A probability of detection of 97%, a probability of false alarm of 2%, and a probability of error of 2.5% are the best results obtained for the Arctic region. C1 [Alonso-Arroyo, A.; Zavorotny, V.

The system has been extended to retrieve variables based on the Global Precipitation Measurement Microwave Imager (GPM/GMI) instrument observed radiances. The inversion algorithm is a One-Dimensional Variational (1DVAR) scheme and is consistent across sensors and uses an iterative approach in which a solution is sought that best fits the observed satellite radiances, subject to other constraints. The Community Radiative Transfer Model (CRTM) is used as the forward and Jacobian operator to simulate the radiances at each iteration prior to fitting the measurements to within the noise level. This paper describes the MiRS retrieval algorithm, its extension to GPM/GMI, and validation against several reference data sets, including National Centers for Environmental Prediction (NCEP) Stage IV precipitation analyses, as well as with the European Centre for Medium-Range Weather Forecasts (ECMWF). Results indicate that MiRS can retrieve details of the atmospheric water vapor, hydrometeors and surface precipitation in an accurate and self-consistent manner.

This presentation describes the way that the OSS is implemented in CRTM, and some preliminary evaluation of the performance of the CRTM-OSS in comparison with CRTM-ODPS method. One of the important benefits of the OSS method is its capability to simulate unapodized radiance, which could lead to better sensitivity in retrievals and data assimilation for numerical weather prediction (NWP). The accuracy and speed of the OSS simulations are two trade-off factors, depending on how many spectral nodes are used during training and simulation. In general, the OSS simulations of hyper spectral IR sensors, such as IASI and CrIS, can archive similar accuracy and double speed as compared to the CRTM-ODPS simulations.

A composite radar scattering model composed of the atmosphere radiative transfer model and the ocean surface Bragg wave theory is employed to analyze the impact of rain on the normalized radar-backscatter cross-section (NRCS) measured in the VV- and cross-polarized C-band Synthetic Aperture Radar (SAR) channels. Our composite model was validated with the matchup of observations of wind speed and rain rate from the SFMR data as well as the NRCSs and incidence angles of C-band VV-polarization SAR data over two hurricanes. Comparisons between the observed NRCSs and the atmosphere part of our model imply that the most important mechanism for the rain effect on the C-band VV polarized SAR hurricane observations is through the influence of waves on the ocean surface. Moreover, the non-Bragg scattering is important for the cross-polarized NRCS simulations. C1 [Perrie, William; Zhang, Guosheng] Fisheries & Oceans Canada, Bedford Inst Oceanog, Dartmouth, NS, Canada.

The difference lies in the non-Bragg scatterings mechanisms including specular reflection and quasi-specular reflection or diffraction on the sharp edges of wave breaking. The specular reflection is a function of radar incidence angle and is negligible for the intermediate incidence angle. The quasi-specular reflection and diffraction on the sharp edges of wave breaking is a function of incidence angle, wind speed and direction. In this study, we adopt the C-band Cross-polarization Ocean (C-2PO) model as the total backscatter from the ocean surface, and assume the non-Bragg scattering as the differences between NRCSs simulated by C-2PO model and composite Bragg model. And a non-Bragg scattering ratio is suggested. With the collocated datasets of wind speeds, wind directions, measured by airborne SFMR and NRCSs from SAR, the suggested non-Bragg scattering ratio is validated.

The present observations were taken in Hurricane Patricia on 23 October 2015 and extend the wind speed range of the existing cross-polarization ocean surface NRCS literature [1]-[4]. The NRCS at the smaller incidence angles decrease as wind speed increases, as expected. At the larger incidence angles, saturation of the NRCS is not observed up to at least 70ms(-1). The results have implications for planned and future scatterometers (e.g., MetOp-SG) that aim to increase the maximum observable wind speeds.

It has 16 spectral solar reflective and emissive bands located in three focal plane modules (FPM): one visible and near-infrared (VNIR) FPM, one midwave infrared (MWIR) FPM, and one longwave infrared (LWIR) FPM. All the AHI bands are geo-spatially calibrated to provide continuous environmental measurements from the Asian-Pacific area for the weather forecasting, disaster monitoring, and long-term climatic change studies. This study is to evaluate the navigation and co-registration accuracies of three AHI bands at the three FPMs using the simultaneous nadir observations (SNO) of Suomi National Polar-orbiting Partnership (SNPP) Visible Infrared Imaging Radiometer Suite (VIIRS) I-band images. The preliminary results showed that the mean navigation difference between the two instruments is within 0.5 AHI pixels at 2km spatial resolution. The AHI band-to-band co-registration (BBR) difference between the two thermal bands is generally less than 0.2 pixels, better than the BBR between the VNIR and IR bands which ranges between 0.2 to 0.7 pixels during the study period.

This study investigates the feasibility of validating the reprocessed VIIRS imagery resolution bands (I-bands, 375 m) SDRs using time series analysis of cloud cover climatology over large metropolitan areas. An I-bands cloud mask algorithm was assessed for cloud detection over urban areas. Reprocessed I-bands SDRs over Beijing, China were generated using the same calibration parameters and VIIRS SDR science code to be used by the future NOAA reprocessing. The operational and reprocessed I-bands SDRs were compared and the impacts of reprocessing on the monthly percent cloud cover time series over Beijing were studied. Our results indicate that monthly percent cloud cover time series over metropolitan area are sensitive to major VIIRS radiometric calibration changes. Therefore, urban cloud climatology can be served as a testbed for the reprocessing of VIIRS I-bands SDRs. C1 [Wang, Wenhui] Earth Resource Technol Inc, 5830 Univ Res Ct, College Pk, MD 20740 USA.

The Suomi NPP VIIRS instrument continues to perform well with a very stable calibration according to extensive comparisons with other instruments and at vicarious validation sites. The calibration accuracy for most bands meet the specification and user needs, although additional efforts are being made to meet more stringent needs such as ocean color applications. The VIIRS Sensor Data Records (SDR) have been operationally used at the Alaska National Weather Service, and have been used to generate a large number of environmental data records ranging from aerosols, fire, to ocean color, sea surface temperature, vegetation, and many others. However, since many updates have been made to the operational processing of VIIRS since launch, inconsistency exists in the long term data records. To address this issue, the VIIRS SDR team is preparing for the reprocessing of the VIIRS historical data using the new automated calibration module RSBAutocal, with the latest calibration coefficients. The reprocessed data will be more consistent over the entire history of VIIRS with all known corrections. At the same time, significant efforts are devoted to the prelaunch calibration of the JPSS J1 VIIRS. While in general the J1 VIIRS performance meets specifications, there are performance waivers and as a result, mitigations have to be developed. This includes the implementation of a new aggregation scheme to address the nonlinear response of the VIIRS Day/Night Band ( DNB). Other waivers include the larger than expected polarization sensitivity which will impact the ocean color bands and additional corrections will be needed postlaunch. In addition, the team has also been performing a trade study for adding a water vapor band to future VIIRS. Many of these efforts have been documented in the VIIRS special issue in the remote sensing open access journal which is being finalized to reach out to a broader user community.

The Visible Infrared Imaging Radiometer Suite (VIIRS) onboard Suomi NPP has 22 bands, however, does not have a water vapor sensing band, and the current VIIRS design cannot make space for additional band. Since the high resolution (375m) imagery band I03 and moderate resolution (750m) band M10, have very similar Spectral Response Functions centered at 1.61 um, it is possible to replace M10 observations with that from I03 to make space for a new water vapor band. However, the impact of removing M10 on different users should be assessed thoroughly. M10 and I03 are mainly used for obtaining surface reflectance at different resolution and for snow detection. M10 can also be used in cloud and aerosol detection, and in detecting night fire from gas flares and combustion sources. In this study, we examined the VIIRS Sensor Data Record (SDR) dataset and compared the radiance from M10 and aggregated I03 (to M10) with different earth observations. At day time, the M10 and I03 have very good agreement, but the radiance ratio between them is affected mainly by the uniformity of I03 pixels and different surface types. Over snow surface, the radiance scatterplot shows less scattered than that with no snow, indicating I03 has similar ability as M10 in snow detection. Limited night datasets indicate radiance of I03 and M10 are different, but I03 may also have superior ability in detecting night fire from gas flares and combustion sources. This study provides an early assessment of the feasibility of aggregating I03 to M10 in order to replace the M10 with a water vapor band.

During geomagnetic storms, auroras can be observed by the DNB on the night side over both hemispheres. The radiometrically calibrated DNB observations can enable quantitative analysis of the spatial distribution and temporal evolution of aurora during geomagnetic storms. Two coronal mass ejections (CME) occurred on June 19 and 21, 2015 and had made their way to Earth to cause a G4 (severe) geomagnetic storm on June 22 afternoon. This paper presents an analysis of the radiance data from DNB observations of the aurora during the geomagnetic storm on June 22, 2015. Regions of aurora during each orbital pass are identified and the evolution of aurora is characterized with time series of the auroral boundary, area and total light emission of the aurora region in the DNB observation. The good correlation of aurora activities with ground geomagnetic index during the geomagnetic storm suggests that DNB observations of aurora can provide new details of the magnetospheric and ionospheric responses during severe geomagnetic storms.

As a result, a number of soil moisture products have been produced from different satellite sensors with different spatial and temporal coverage and quality. To make effective use of all available soil moisture products, a Soil Moisture Operational Product System (SMOPS) has been developed at National Oceanic and Atmospheric Administration (NOAA) to produce a one-stop shop for all operational soil moisture products from different satellite sensors. To increase the spatial and temporal coverage of soil moisture product, SMOPS also provides a data layer that merges soil moisture retrievals from multiple satellites in addition to the individual soil moisture retrievals from each of the available satellites. This paper gives an overall introduction of SMOPS and its validations using ground measurements.

The current NOAA operational GVF product is derived from AVHRR top of atmosphere NDVI data. As part of the NOAA SNPP Data Exploitation (NDE) program, NOAA scientists developed a new near real time GVF product, which is based on the Enhanced Vegetation Index (EVI) derived from the VIIRS sensor onboard the SNPP satellite. The GVF product has two components. The first GVF product has global coverage at 4 km resolution, and the second GVF product is regional (Lat 90 degrees N - 7.5 degrees S, Lon 130 degrees E - 30 degrees E) at 1km resolution. Both GVF products are weekly composites, updated daily based on the past week's data. This new VIIRS GVF product has been operational and available to the public on the NOAA Comprehensive Large Array-data Stewardship System (CLASS) since February 2015. The retrieval algorithm of the VIIRS GVF product uses VIIRS red (I1), near-infrared (I2) and blue (M3) bands centered at 0.640 mu m, 0.865 mu m and 0.490 mu m, respectively, to calculate the Enhanced Vegetation Index (EVI). A novel weekly EVI compositing method is used to select the optimal observations for each grid cell. High frequency noise in EVI time series is reduced by applying a digital smoothing filter on EVI. GVF is calculated by comparing the smooth EVI against the global maximum and minimum EVI values assuming a linear relationship between EVI and GVF. More validation work and testing is needed to determine the benefits of the new VIIRS GVF product over the AVHRR GVF product.

Research shows an increasing trend of baseflow over the last 60 years and may be due to this artificial drainage activity. The influence of tile drainage on streamflow has been studied using in situ measurements and hydrological models. Evapotranspiration (ET) is an important component of hydrologic cycle. However, the impact of tile drainage on ET, or on other components of the water budget, is not well documented. In this study, we applied an energy balance based multi-sensor (GOES, MODIS and Landsat) data fusion method to estimate daily 30 m ET over an intensively drained area in South Dakota, USA to assess the model performance and further explore the spatial and temporal ET patterns through 2004-2013 and their relationship to drain installation.

The depth profile of chlorophyll concentration can be estimated by airborne backscatter lidar. Both the attenuation of a lidar pulse and the volume backscattering coefficient depend on chlorophyll concentration, and these dependences can be used in an iterative retrieval to estimate the chlorophyll profile. The chlorophyll concentration profile can also be used to estimate the attenuation of sunlight with depth, which can be used with a measurement of the incident sunlight at the aircraft to estimate the light level profile. The temperature profile is more difficult, but the sea-surface temperature can be measured from the aircraft and this temperature is constant through the mixed layer. The technique is illustrated using data from a lidar and visible and infrared radiometers on an aircraft over the Gulf of Mexico.

The Joint Polar Satellite System (JPSS) is the National Oceanic and Atmospheric Administration's (NOAA) next generation polar satellite program that provides global environmental remote sensing of weather, climate and other environmental applications. The Suomi National Polar-orbiting Partnership (S-NPP) satellite launched in October 2011 was the first satellite designed to bridge into the future JPSS constellation. The data products produced from the S-NPP/JPSS satellites provide critical observations for accurate weather forecasting, reliable severe storm outlooks, and global measurements of atmospheric and oceanic conditions such as sea surface temperatures, ocean color, ozone and other trace gases, aerosol, clouds, temperature and moisture profiles, wind speeds, land surface properties, snow and ice covers, etc. S-NPP/JPSS products provides critical support to NOAA's ecosystems, climate, weather, and water mission goals through numerous operational applications, including weather and climate modeling and prediction, fisheries management; ecosystem monitoring and management; and understanding ocean dynamics and climate variability. This paper will provide insight into the Suomi National Polar-orbiting Partnership (S-NPP) data products and their applications for environment monitoring. Specifically, the presentation will be focused on the advanced data products derived from the Cross-track Infrared Sounder (CrIS) measurements, Cal/Val status, products performance, and their applications for monitoring the atmospheric variability.

The primary application users of the SMAP radiometer observations include numerical weather prediction operations that require shorter data latency (e. g. less than 6 hours). With slightly simplified algorithms of the L1B-TB data, NASA SMAP project is also providing near real time (NRT) L1B-TB data to NOAA operational users with a latency ranging from 2-6 hours. With this latency NOAA NWP models could use most of those SMAP half-orbit data that arrives within the 6 hour cut-off time limit. Before a radiance data assimilation capability for NOAA NWP models is developed, NOAA NESDIS is retrieving soil moisture from the NRT L1B-TB data through its Soil Moisture Product System (SMOPS) and makes surface soil moisture directly available for assimilation into the NWP models with the shortest possible turn-around time. Unlike using NASA GEOS model surface and soil temperature and multi-year average vegetation index data, SMOPS soil moisture retrieval algorithm uses the surface temperature data from operational Global Forecast System (GFS) and the vegetation index (NDVI) data from the near real time Suomi-NPP VIIRS observations. This paper introduce the structure of SMOPS, the soil moisture retrieval algorithm for SMAP data, and validation of the soil moisture data products against in the situ soil moisture measurements collected from the Soil Climate Analysis Networks of US Department of Agriculture and the Tibetan Soil Moisture Networks of Chinese Academy of Sciences. The soil moisture data retrieved from SMAP NRT TB data through SMOPS are also evaluated against the NASA official SMAP Level 2/3 soil moisture products. Preliminary validation results indicate that the SMAP soil moisture product from the SMAP NRT TB data and NESDIS SMOPS has similar quality to the NASA official products, but has shorter latency which may be critical to NOAA NWP operations.

This is an opportunity to design a modern architecture with no preconceived notions regarding instruments, platforms, orbits, etc., but driven by user needs. The NSOSA study team will develop and evaluate architecture alternatives, to include partner and commercial alternatives that are likely to become available. The objectives will include both functional needs and strategic characteristics (e. g., resiliency, flexibility, responsiveness, sustainability). The study will be informed by the Space Platform Requirements Working Group (SPRWG), commissioned by NESDIS. The SPRWG is charged to assess new or existing user needs and to provide relative impacts from different candidate observing systems in the future architecture. SPRWG results will serve as input to the process for new foundational (Level 0 and Level 1) requirements for the next generation of NOAA satellites that follow the GOES-R, JPSS, DSCOVR, Jason-3, and COSMIC-2 missions.

It will inter-calibrate the instruments of the international constellation of operational low-earth-orbiting (LEO) and geostationary (GEO) environmental satellites and tie these to common reference standards to assure the comparability of satellite measurements taken at different times and locations by different instruments operated by different satellite agencies. Upon its 10th anniversary the GSICS community is gradually encompassing all CGMS members. CGMS members are collaborating in the framework of GSICS to develop and apply "best practices" for state-of-the-art and homogeneous calibration. GSICS benefits to satellite operators through sharing of resources and best practices, and to satellite data users through improved calibration, assessments, and traceability to common references. The practical value of GSICS was demonstrated in the role played to facilitate the commissioning operations of several satellite programmes in the most recent years.

This constellation is capable of covering the entire globe every two hours. With six more satellites added and properly arranged, a constellation is able to provide hourly observations of fast-evolving severe weather systems like hurricanes. Compared to current polarorbiting satellite which normally carries one passive microwave instrument onboard, a small satellite constellation is more cost-effective, requires a shorter development cycle and has smaller failure impact. NOAA Center for Satellite Applications and Research (STAR) has built a full radiance transformation system (ARTS) that is applicable for small satellite calibration, validation and data processing. Hourly NWP forecast fields for tropical storm Debby (2012) will be produced and used as inputs to Community Radiative Transfer Model (CRTM) to simulate the designed microwave small satellite observations to demonstrate their values for monitoring and predicting hurricane and typhoon events.

The sensitivity of the SGR-ReSI measurements to the ocean surface winds and waves are characterized. The effects of sea surface temperature, wind direction, and rain are also investigated. The SGR-ReSI measurements exhibited sensitivity through the entire range of wind speeds sampled in this dataset, up to 35 m/s. A significant dependence on the larger waves was observed for winds < 6 m/s. Additionally, an interesting dependence on SST was observed where the slope of the SGR-ReSI measurements is positive for winds < 5 m/s and reverses for winds > 5 m/s. There appeared to be very little wind direction signal, and investigation of the rain impacts found no apparent sensitivity in the data. These results are shown through the analysis of global statistics and examination of a few case studies. This released SGR-ReSI dataset provided the first opportunity to comprehensively investigate the sensitivity of satellite-based GNSS-R measurements to various ocean surface parameters. The upcoming NASA's Cyclone Global Navigation Satellite System (CYGNSS) satellite constellation will utilize a similar receiver to SGI-ReSI and thus this data provides valuable pre-launch knowledge.

With the development of full-polarization Synthetic Aperture Radar (POL-SAR) imaging, these terrains from coastal zone classification are available. But the classification of coastal land-use types based on full-polarization SAR data has not been investigated. In fact, the signal return coming from the sea can be frequently indistinct from one coming from the land. And coastal zone terrains modeled as a strong multiplicative noise as well as they are very similar with scattering mechanism, which makes the coastline zone types classification a very complicated issue. A joint sparse representation-based method for classification of coastal land-use types with full-polarization SAR data is proposed in this paper.

Specifically, VIIRS ocean color products include normalized water-leaving radiance spectra nL(w)(lambda) at VIIRS five spectral bands, chlorophyll-a concentration (Chl-a), water diffuse attenuation coefficients at the wavelength of 490 nm, K-d(490), and at the domain of photosynthetically available radiation (PAR), K-d(PAR). VIIRS ocean color products derived from the NOAA Multi-Sensor Level-1 to Level-2 (MSL12) ocean color data processing system are evaluated and compared routinely with in situ data from the Marine Optical Buoy (MOBY) and several AERONET-OC sites. In order to meet requirements from all users, we propose to routinely produce two ocean color data streams, i.e., the near-real-time (NRT) data and delayed science quality data. The NRT ocean color data stream has the advantage of quick data turn around with data latency similar to 12-24 hours, while the science quality data stream has high consistence (with the mission-long data reprocessing) and accuracy of ocean color products. In addition, we have significantly improved on-orbit sensor calibration by combining the lunar calibration into the current solar calibration method. Our results show that VIIRS is now providing high-quality global ocean color products in support of the scientific research and operational applications.

A second VIIRS instrument will be on the next Joint Polar Satellite System (JPSS) satellite (J-1) that is planned to be launched in early 2017. VIIRS is a scanning radiometer that consists of 22 spectral channels with band centers from 412 nm to 12,050 nm. It collects imagery and radiometric measurements of the land, atmosphere, cryosphere, and oceans. The VIIRS data processing is done at NOAA Interface Data Processing Segment (IDPS) which is also responsible for creating all other atmospheric, land and ocean products from the other sensors on board S-NPP. The testing and integration of algorithm and Look-Up-Table (LUT) updates are done by using Algorithm Development Library, a test system that mimics the operational system. In this work we will present the testing and integration work conducted for Aerosol Environmental Data Record (EDR) Algorithm improvements. As Aerosol EDR is used in many downstream products, we will present the effect of Aerosol EDR updates on those products. We will also discuss the effect of changes to upstream VIIRS Sensor Data Record (SDR) and Cloud Mask algorithms on the Aerosol EDR products.

Predictions are produced beyond midnight of the following day at 12 km spatial and hourly temporal resolution and are available at http:// airquality. weather. gov/. Ozone predictions and testing of fine particulate matter (PM2.5) predictions combine the NOAA National Centers for Environmental Prediction (NCEP) operational North American Mesoscale (NAM) weather predictions with inventory based emission estimates from the EPA and chemical processes within the Community Multiscale Air Quality (CMAQ) model. Predictions of smoke and dust from dust storms use the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model. Verification of ozone and developmental aerosol predictions relies on AIRNow compilation of observations from surface monitors. Verification of smoke and dust predictions uses satellite retrievals of smoke and dust. Ozone prediction accuracy is maintained in recent years, while pollution sources are changing, through updates in emission source estimates and updates in the model configuration. Emissions for operational ozone predictions were updated using EPA projections of mobile sources for 2012. Trends in NOx from satellite and ground observations show a good agreement with emission updates over large U.S. cities. Updated CMAQ model with CB05 mechanism and AERO4 aerosol module was implemented for operational ozone prediction in January 2015. Updates include monthly varying lateral boundary conditions, modified dry deposition, constraints on minimum planetary boundary height, and changes to the lifetime of organic nitrate. Testing of PM2.5 predictions from the same system modulates soil emissions by snow and ice cover, and includes emissions of windblown dust and particles emitted from forest fires. Further development of PM2.5 predictions will explore bias correction approaches. Longer-term plans include comprehensive linkages between NAQFC predictions for the U.S. and global atmospheric composition predictions, as resources allow.

It is important to optimize the combination and placement of these wide ranges of measurements and data acquisition options for cost-effectiveness. Under this initiative we attempt to quantify the gain by a regional state-of-the-science chemical data assimilation and chemical transport modeling system when incremental sets of observation are acquired into the system. This study represents a first step in a series of steps to ingest such proposed incremental additions of observation. The efficacy of such proposals is quantified systematically by Observation Simulation System Experiments (OSSEs). We compared two end-to-end regional air quality forecasting simulations using: (a) the Weather Forecasting and Research (WRF) regional application initialized by the U.S. national Weather Service (NWS) Global Forecasting System (GFS) coupled with the U.S. Environmental Protection Agency Community Multi-scale Air Quality (CMAQ) chemical model (Byun and Schere 2006), and (b) the same as above but with a new GFS enhanced by assimilating a fictitious addition of Atmospheric Infrared Sounder (AIRS) retrieved radiances at 13 km spatial resolution at nadir from a proposed geostationary satellite positioned over 75oW staring over the U. S. Both sensitivity runs were performed in 12 km horizontal grid resolution and with daily initialization for 12 days between July 29 and August 9 2005. Noticeable forecast skill improvement in surface concentration for O-3 and particulate matter smaller than 2.5 mu m in diameter (PM2.5) was achieved.

NAQFC focuses on surface ozone and PM2.5 (particle matter with diameter <2.5 mu m), which impacts human-health. Near surface ozone mainly comes from photochemical reactions of NOx and volatile organic compounds (VOCs). Its sources in upper layers could come from either long-range transport or stratospheric ozone. Most PM2.5 comes from near-surface primary emissions or secondary generation from photochemical reactions. During the summer 2014 NASA Discover-AQ-Colorado program, the NOAA Air Resources Laboratory (ARL) provided a real-time forecast in support of aircraft measurements with 12 km CONUS (Contiguous United States) and 4 km nested domains. Here we compare the model results with the aircraft data to investigate our predictions.

Its design goal is to achieve high throughput on virtually all modern 64-bit processors, that nowadays already have native instructions for AES. To achieve this goal, Simpira uses only one building block: the AES round function. For b = 1, Simpira corresponds to 12-round AES with fixed round keys, whereas for b >= 2, Simpira is a Generalized Feistel Structure (GFS) with an F-function that consists of two rounds of AES. We claim that there are no structural distinguishers for Simpira with a complexity below 2(128), and analyze its security against a variety of attacks in this setting. The throughput of Simpira is close to the theoretical optimum, namely, the number of AES rounds in the construction. For example, on the Intel Skylake processor, Simpira has throughput below 1 cycle per byte for b <= 4 and b = 6. For larger permutations, where moving data in memory has a more pronounced effect, Simpira with b = 32 (512 byte inputs) evaluates 732 AES rounds, and performs at 824 cycles (1.61 cycles per byte), which is less than 13% off the theoretical optimum. If the data is stored in interleaved buffers, this overhead is reduced to less than 1%. The Simpira family offers an efficient solution when processing wide blocks, larger than 128 bits, is desired.

These new products will improve our understanding of the spatial variability of aerosols in urban areas and will be useful in the detection of localized aerosol emissions. Urban aerosol retrieval is challenging for existing algorithms because of the high spatial variability of the surface reflectance, indicating the need for improved urban surface reflectance models. This problem can be stated in the language of novelty detection as the problem of selecting aerosol parameters whose effective surface reflectance spectrum is not an outlier in some space. In this paper, empirical orthogonal functions, a reconstruction-based novelty detection technique, is used to performsingle-pixel aerosol retrieval using the single angular and temporal sample provided by the MODIS sensor. The empirical orthogonal basis functions are trained for different land classes using the MODIS BRDF MCD43 product. Existing land classification products are used in training and aerosol retrieval. The retrieval is compared against the existing operational MODIS 3 KM Dark Target (DT) aerosol product and co-located AERONET data. Based on the comparison, our method allows for a significant increase in retrieval frequency and a moderate decrease in the known biases of MODIS urban aerosol retrievals.

This is even more important when it comes to periodic configuration updates to a large number of such devices belonging to one or more groups. One solution could be to take a group of devices as a unit of control and then manage them through a group communication mechanism. An obvious challenge to this approach is how to create such groups dynamically and manage them securely. Moreover, there need to be mechanisms in place by which members of the group can be removed and added dynamically. In this paper, we propose a technique that has been recently standardized in IEEE 802.21 (IEEE Std 802.21d (TM)-2015) with the objective of providing a standard-based solution to the above challenges. The approach relies on Logical Key Hierarchy (LKH) based key distribution mechanism but optimizes the number of encryption and decryption by using "Complete Subtree". It leverages IEEE 802.21 framework, services, and protocol for communication and management, and provides a scalable and secure way to manage (e.g., add and remove) devices from one or more groups. We describe the group key distribution protocol in details and provide a security analysis of the scheme along with some performance results from a prototype implementation.

VIIRS data from all spectral bands became available three months after launch when all infrared-band detectors were cooled down to operational temperature. Before that, VIIRS sensor data record (SDR) products were successfully generated for the visible and nearinfrared (VNIR) bands. Although VIIRS calibration has been significantly improved through the four years of the SNPP mission, SDR reprocessing for this early mission phase has yet to be performed. Despite a rapid decrease in the telescope throughput that occurred during the first few months on orbit, calibration coefficients for the VNIR bands were recently successfully generated using an automated procedure that is currently deployed in the operational SDR production system. The reanalyzed coefficients were derived from measurements collected during solar calibration events that occur on every SNPP orbit since the beginning of the mission. The new coefficients can be further used to reprocess the VIIRS SDR products. In this study, they are applied to reprocess VIIRS data acquired over pseudo-invariant calibration sites Libya 4 and Sudan 1 in Sahara between November 2011 and February 2012. Comparison of the reprocessed SDR products with the original ones demonstrates improvements in the VIIRS calibration provided by the reprocessing. Since SNPP is the first satellite in a series that will form the Joint Polar Satellite System (JPSS), calibration methods developed for the SNPP VIIRS will also apply to the future JPSS measurements.

The first satellite in the series is planned for launch in November 2016. The satellite will carry six instruments dedicated to the study of the Earth's weather, lightning mapping, solar observations, and space weather monitoring. Each of the six instruments require specialized calibration plans to achieve their product quality requirements. In this talk we will describe the overall on-orbit calibration program and data product release schedule of the GOES-R program, as well as an overview of the strategies of the individual instrument science teams. The Advanced Baseline Imager (ABI) is the primary Earth-viewing weather imaging instrument on GOES-R. Compared to the present on-orbit GOES imagers, ABI will provide three times the spectral bands, four times the spatial resolution, and operate five times faster. The increased data demands and product requirements necessitate an aggressive and innovative calibration campaign. The Geostationary Lightning Mapper (GLM) will provide continuous rapid lightning detection information covering the Americas and nearby ocean regions. The frequency of lightning activity points to the intensification of storms and may improve tornado warning lead time. The calibration of GLM will involve intercomparisons with ground-based lightning detectors, an airborne field campaign, and a ground-based laser beacon campaign. GOES-R also carries four instruments dedicated to the study of the space environment. The Solar Ultraviolet Imager (SUVI) and the Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) will study solar activity that may affect power grids, communication, and spaceflight. The Space Environment In-Situ Suite (SEISS) and the Magnetometer (MAG) study the in-situ space weather environment. These instruments follow a calibration and validation (cal/val) program that relies on intercomparisons with other space-based sensors and utilize special spacecraft maneuvers. Given the importance of cal/val to the success of GOES-R, the mission is committed to a long-term effort. This commitment enhances our knowledge of the long-term data quality and builds user confidence. The plan is a collaborative effort amongst the National Oceanic and Atmospheric Administration (NOAA), the National Institute of Standards and Technology (NIST), and the National Aeronautics and Space Administration (NASA). It is being developed based on the experience and lessons-learned from the heritage GOES and Polar-orbiting Operational Environmental Satellite (POES) systems, as well as other programs. The methodologies described in the plan encompass both traditional approaches and the current state-of-the-art in cal/val.

The problem of identifying graphlets embedded within a larger graph is a larger implementation of the graph isomorphism problem, with no known polynomial time algorithmic solution. One common method to identify the class of a given subgraph embedded within a supergraph is to make a degree list, called a signature, of it, and compare it to a list of known signatures and their corresponding graphlets. However, some graphlets have the same signature. Extra processing is needed to differentiate between them, and the existing method for determining how to differentiate them is by inspection and on a case by case basis. This paper proposes an algorithm to differentiate graphlets with identical signatures which significantly outperforms the existing method. A search space reduction technique is also proposed to reduce the computation cost. C1 [Alumbaugh, John Calvin; Li, Qinghua] Univ Arkansas, Dept Comp Sci & Comp Engn, Fayetteville, AR 72701 USA.

Nonetheless, energy consumption will be non-negligible when a large number of small-cell Base Stations (BSs) are densely deployed. One practical and effective approach to reduce the energy consumption of the UDN is through dynamically controlling the power saving mode of BSs, while the challenge is to maintain network coverage and satisfy the performance requirements of User Equipment (UEs). In this paper, we formalize the problem of minimizing the energy consumption of BSs by optimally controlling the BS's power saving mode (switching between awake mode and sleep mode). We focus on optimal BS selection with the objective of energy efficiency, while the considering the constraints of the coverage of UEs, the capacity of BSs, and the data rate UEs. To validate the effectiveness of our proposed scheme, we have conducted performance evaluations with a comprehensive scenario design, consisting of UE density, distribution, and mobility, as well as BS deployment. The evaluation results demonstrate favorable energy efficiency improvement at averages of 38.82 % and 48.05 % in scenarios where UEs are uniformly distributed and non-uniformly distributed in the network. Meanwhile, network coverage and UE's Quality of Service (QoS) requirements are provided. C1 [Yu, Wei; Xu, Hansong; Hematian, Amirshahram] Towson Univ, Towson, MD 21252 USA.

Plasma samples were collected during 2003-2004 from two free-ranging dolphin populations (Charleston [CHS], South Carolina, n = 72; Indian River Lagoon [IRL], Florida, n = 79). Circulating levels of the following vitamins were analyzed: alpha- and gamma-tocopherols, retinol, retinyl palmitate, and ascorbic acid. Site-specific differences were observed for alpha-tocopherol, retinyl palmitate, and ascorbic acid, with higher levels occurring in CHS dolphins. Reference intervals (50th, 75th, and 90th percentiles) were calculated for each dolphin population. Higher levels of alpha-tocopherol were observed in CHS female dolphins compared to males (p = 0.05), with a similar trend observed in IRL. This study provides reference intervals for estuarine bottlenose dolphin (Tursiops truncatus) populations at two southeastern U.S. sites. Such data on baseline vitamin concentrations in wild populations are necessary prerequisites for understanding the impacts of contaminants or other disruptions of vitamin homeostasis on overall animal health.

Herein, we examined data for 136 Florida manatees that were rehabilitated and released with telemetry tags between 1988 and 2013 to determine release outcome of each individual as either success (acclimation) or failure after at least 1 y. Ten predictor variables were statistically evaluated for potential relationships to release outcome. To assess the contribution of each predictor variable to release outcome, each variable was tested for significance in univariate analyses. Manatees born in captivity experienced poor success after release (14%), whereas the overall success of wild-born individuals was higher (72%). When compared with other variables in our dataset, number of days in captivity was the strongest predictor for determining success. Manatees rescued as calves and held in captivity for more than 5 y had a high likelihood of failure, while subadults and adults had a high likelihood of success, regardless of the amount of time spent in captivity. Ensuring the success of individual manatees after release is critical for evaluating the contribution of the manatee rehabilitation program to the growth of the wild population.

Deposition was performed in a CoSO4 + CoCl2 + H3BO3 electrolyte with a branched polyethyleneimine (PEI) as a suppressing additive. Voltammetric measurements, including the impact of rotation rate and suppressor concentration on the rate of metal deposition, were used to quantify the interplay between metal deposition and suppressor adsorption. The derived kinetics were used in a model based on additive derived S-shaped negative differential resistance (S-NDR) to predict bottom-up filling of patterned features. The predictions, including the impact of deposition potential and additive concentration on the feature filling, are shown to match experimental results for filling of TSVs. This work parallels previous work with Ni and extends previous understanding and application of additive derived S-NDR that also includes prediction and demonstration of superconformal, bottom-up deposition and filling of TSVs with Cu, Au and Zn.

The investigationwas conducted on aluminum rotating disk electrodes as a function of potential, ionic liquid composition, and temperature. Two different dissolutionmechanisms were realized. Atmodest overpotentials, dissolution takes place under mixed kinetic-mass transport control. However, as the overpotential is increased to induce higher dissolution rates and/or the ionic liquid is made more acidic, the dissolution reaction transitions to a potential-independent passivation-like process ascribed to the formation of a porous solid layer of AlCl3(s). At a fixed temperature and composition, the limiting passivation current density displays Levich behavior and also scales linearly with the concentration of AlCl4- in the ionic liquid. The heterogeneous kinetics of the Al dissolution reaction were measured in the active dissolution potential regime. The exchange current densities were independent of the composition of the ionic liquid, and the anodic transfer coefficients were close to zero and seemed to be independent of the Al grain size.

Based on these two genes, two and three distinct clades with geographic signals were revealed on the phylogenetic trees respectively. The divergence between these clades was estimated to occur in the late Pleistocene. Analysis of molecular variance and pairwise FST suggested a high rate of gene flow among individuals sampled from the Chinese coast, but with obvious genetic differentiation from the Malaysian population. Mismatch distribution and neutrality tests indicated that the T. nebulosi population experienced expansion in Pleistocene low sea level periods. Vicariance was considered to account for the genetic divergence between Chinese and Malaysian populations, while sea level fluctuations and mainland-island connections during glacial cycles were associated with the slight genetic divergence between the populations along the mainland coast of China and those off Sanya. On the contrary, oceanographic circulations and host migration could lead to genetic homogeneity of populations distributed along the mainland coast of China.

While polymer-grafted nanoparticles (GNP) of this kind typically have a spherical average shape after grafting even a moderate number of chains, their instantaneous molecular shape can fluctuate significantly due to the deformation of the grafted chains. Both simulations and measurements have previously revealed that these "conformationally polarizable'' particles can exhibit self-assembly into large scale polymeric structures in both solution and in polymer melts, and we simulate polymer-grafted nanoparticles with D and temperature (T) variations without a dispersing solvent to better understand the nature of this self-assembly process. We observe a reversible self-assembly into linear and branched dynamic GNP structures, where the extent of the assembly and geometry depend on D and T, and we constructed a map capturing the GNP structural behavior with D and T variations. Since the shape of the GNPs appeared to be correlated with the occurrence of the GNP self-assembly, we quantified the average shape and a measure of shape fluctuations to better understand how molecular shape influences their propensity to self-assemble into different structural forms. Based on this framework, we describe the clustering process of the GNPs as an equilibrium polymerization phenomenon and we calculate the order parameter governing the dynamic clustering behavior of GNPs, the average mass of the clusters, size distribution, and the apparent fractal dimension of the clusters.

To better understand the role of troubleshooting in electronics laboratory courses, we interviewed 20 electronics instructors from multiple institution types about their beliefs and teaching practices related to troubleshooting. In these interviews, instructors articulated the idea that nothing works the first time in multiple contexts pertaining to troubleshooting. We argue that this idea is an expert epistemology and show how it informs instructors' beliefs that (i) students need to know how to troubleshoot, (ii) students should expect to troubleshoot, (iii) all circuit-building lab activities provide opportunities for students to troubleshoot, and (iv) students' ability to construct functional circuits can be a proxy for their ability to troubleshoot malfunctioning circuits. Moreover, we discuss implications for instruction and assessment of troubleshooting in electronics courses. C1 [Dounas-Frazer, Dimitri R.; Lewandowski, H.

However, the way ownership manifests, as well as how it is developed, has not been a focus of study within the physics education research community. As a first step toward understanding what ownership looks like in this context, we are studying students' ownership of their projects in two upper-division optics courses, in which ownership is an explicit learning goal. We utilized data from the Project Ownership Survey (POS), as well as student interviews that focus on their interests, challenges, and memorable moments. The results of the POS were conflicted one portion of the survey indicated high ownership while those questions pertaining to student affect indicated otherwise. However, analysis of our interviews corroborated that students were experiencing several aspects of ownership, but the nature of their affective response was complex and dynamic.

Considerable work has been done to develop curricular materials and pedagogical techniques designed to enhance student learning within laboratory learning environments. Examples of these transformation efforts include the Investigative Science Learning Environment (ISLE), Modeling Instruction, and integrated lab/lecture environments (e.g., studio physics). In addition to improving students' understanding of the physics content, lab courses often have an implicit or explicit goal of increasing students' understanding and appreciation of the nature of experimental physics. We examine students' responses to a laboratory-focused epistemological assessment the Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS) to explore whether courses using transformed curricula or pedagogy show more expert-like student epistemologies relative to courses using traditional guided labs, as well as how this trend varies based on student major or gender. Data for this study are drawn from an existing data set of responses to the E-CLASS from multiple courses and institutions. C1 [Wilcox, Bethany R.; Lewandowski, H.

Otolith treatment experiments determined the stability of trace elements. Hydrogen peroxide treatment slightly affected Mn, Sr, and Ba, but it removed 35%-43% of Mg and 51% of P. Growth experiments identified ontogenetic and temperature factors that influenced trace element composition. Otolith weight was a major determinant of composition. Mn, Sr, and Ba each had unique ontogenetic and temperature responses. Mg/Ca and P/Ca ratios covaried and decreased with growth at 16 degrees -19 degrees C but increased with growth at 21 degrees C. The decrease in Mg/Ca and P/Ca ratios with age was nonconservative, i.e., the total mass of initially deposited Mg and P decreased as the otoliths grew. The results contradict the assumption that all deposited trace elements are permanently incorporated in otoliths in living fish.

TI ANOMALOUS EPIPELAGIC MICRONEKTON ASSEMBLAGE PATTERNS IN THE NERITIC WATERS OF THE CALIFORNIA CURRENT IN SPRING 2015 DURING A PERIOD OF EXTREME OCEAN CONDITIONS SO CALIFORNIA COOPERATIVE OCEANIC FISHERIES INVESTIGATIONS REPORTS LA English DT Article ID EL-NINO; SOUTHERN CALIFORNIA; ROCKFISH SEBASTES; CURRENT SYSTEM; PACIFIC; ABUNDANCE; STATE; ZOOPLANKTON; DYNAMICS; IMPACTS AB We report on the anomalous distribution, abundance, and community structure patterns of epipelagic micronekton from a midwater trawl survey in May-June 2015 that has a 26-year time series within a core region off central California (36 degrees 35'-38 degrees 10'N) and a 12-year time series with expanded spatial coverage (extending from 32 degrees 42.5'-39 degrees 50'N). The 2015 survey took place during an extended period of record-breaking warm surface temperatures in much of the northeast Pacific Ocean. In the neritic waters off central and northern California, this broad-scale extended marine heat wave was combined with more localized, above average coastal upwelling in spring 2015 that led to slightly cooler than normal surface temperatures over the continental shelf and shelf break. The unusual micronekton assemblages in our 2015 trawl survey featured anomalously high catches of warm water species such as pelagic red crabs (Pleuroncodes planipes), coincident with high catches of colder water species such as YOY rockfish (Sebastes spp.), and also large catches of pelagic tunicates such as Pyrosoma atlanticum. Principal component analysis (PCA) on a subset of the most frequently occurring species for both the shorter time series (expanded survey area) and the longer time series (core region) yielded similar results to previous studies off central California, with a suggested alternation between micronekton communities dominated by coastal pelagic species and those dominated by YOY groundfish (rockfish, Pacific hake [Merluccius productus], and sanddabs [Citharichthys spp.]), krill, and cephalopods. In addition, the leading principal components for the different regions of the expanded survey area were highly correlated, suggesting similar micronekton community responses to forcing mechanisms over a broad spatial scale. As the PCA analysis was limited to a relatively small subset of species and the time series for some frequently encountered species are not continuous throughout the history of the survey, we also report on species that reflect additional aspects of the unusual nature of the 2015 survey catches. Together, these results indicate that the micronekton community structure in the late spring of 2015 was highly anomalous in that species characteristic of what might generally be considered three different nominal states (YOY groundfish/market squid and krill, warm-water subtropical species, and pelagic tunicates) were all encountered in high abundance.

Hafner, Jan TI Analysis of flight MH370 potential debris trajectories using ocean observations and numerical model results SO JOURNAL OF OPERATIONAL OCEANOGRAPHY LA English DT Article AB Malaysian Airlines flight MH370 disappeared in March 2014. Potential sites of where the plane entered the water are considered within a vast region of the Indian Ocean. We present a methodology to assess the potential crash site based on where airplane debris was found, with an emphasis on the first debris discovery on Reunion Island. This methodology uses the historical dataset of surface drifters and numerical modeling results. Marine debris, depending on its buoyancy, is exposed to varying amounts of wind, and we conducted tests for a suite of different scenarios. The methodology proposed here enables us to generate fields of particle density probability to assess debris trajectories and, therefore, hypothesize on the potential crash site. We provide an estimate of the most likely windage affecting floating debris on its way to Reunion Island by assuming the plane entered the sea in the defined search area. Our results indicate that areas within the Indian Ocean subtropical gyre, including the search area, could be a source of the debris found on Reunion Island. We also identify zones that can be excluded as potential crash sites and provide estimated travel times and probable ashore positions of plane debris through an analysis of the historical surface drifter dataset. Recent discoveries of new debris linked to flight MH370 in Mozambique, South Africa, Mauritius, and Tanzania are consistent with our results and confirm the general westward drift and travel time of debris from the search area.

Understanding this interconnectivity is the first step in building process control models that help make the process more repeatable and reliable. Metamodels can be used to conceptualize models of complex AM processes and capture diverse parameters to provide a graphical view using common terminology and modeling protocols.

One of them is the lack of understanding of the complex relationships between the numerous physical phenomena occurring in these processes. Metamodels can be used to provide a simplified mathematical framework for capturing the behavior of such complex systems. At the same time, they offer a reusable and composable paradigm to study, analyze, diagnose, forecast, and design AM parts and process plans. Training a metamodel requires a large number of experiments and even more so in AM due to the various process parameters involved. To address this challenge, this work analyzes and prescribes metamodeling techniques to select optimal sample points, construct and update metamodels, and test them for specific and isolated physical phenomena. A simplified case study of two different laser welding process experiments is presented to illustrate the potential use of these concepts. We conclude with a discussion on potential future directions, such as data and model integration while also accounting for sources of uncertainty.

These technologies can provide decision-making support to manufacturers through improved monitoring, analysis, modeling, and simulation that generate more and better intelligence about manufacturing systems. However, challenges and barriers have impeded the adoption of smart manufacturing technologies. To begin to address this need, this paper defines requirements for data-driven decision making in manufacturing based on a generalized description of decision making. Using these requirements, we then focus on identifying key barriers that prevent the development and use of data-driven decision making in industry as well as examples of technologies and standards that have the potential to overcome these barriers. The goal of this research is to promote a common understanding among the manufacturing community that can enable standardization efforts and innovation needed to continue adoption and use of smart manufacturing technologies.

The key technologies to enable composability are discussed along with a suite of tools that assist designers in the management of data, models and knowledge components. A proof-of-concept case study demonstrates the potential of the AM analytical framework. C1 [Lu, Yan; Witherell, Paul; Assouroko, Ibrahim] NIST, Gaithersburg, MD 20899 USA.

The repository is envisioned to include several new use cases in the context of information use in smart manufacturing. This paper examines several key benefits through usage scenarios engaging existing engineering activities. Based on the scenarios, the desired characteristics of an open web-based repository are presented, namely that it will be (1) complementary to existing practices, (2) open and net centric, (3) able to enforce model consistency, (4) modular (5) extensible, and (5) able to govern contributions. A repository will support and motivate the ubiquitous and extended use of standardized representations of unit manufacturing processes in order to promote consistency of performance assessments across industries and provide a tangible, data-driven perspective for analysis-related activities. Furthermore, the paper presents additional benefits and possible applications that could result from a shared manufacturing repository.

Manufacturers have actively improved the sustainability of their products through the use of such tools and methods. However recently, manufacturers are struggling to maintain the necessary gains in energy and material efficiency due to the assessment inaccuracies of current ad hoc methods and their inability to identify large sustainabilizy improvement opportunities. Overcoming this barrier requires standardized methods and tools that are implementable and which contain accurate manufacturing process-level information. To aid in developing such methods and tools, this study contrasts the perspective of industry and academic research on the topics of sustainable manufacturing metrics and measurements, and process modeling to determine the deficits that exist in enacting academic theory to practice. Furthermore, this study highlights some of the industry responses to the development of related standards for sustainability assessment.

TI Methylammonium lead iodide grain boundaries exhibit depth-dependent electrical properties SO Energy & Environmental Science LA English DT Article ID PEROVSKITE SOLAR-CELLS; CH3NH3PBI3 PEROVSKITE; HIGH-PERFORMANCE; EFFICIENCY; FILMS; STATE; RECOMBINATION; PASSIVATION; HYSTERESIS; LIGHT AB In this communication, the nanoscale through-filmand lateral photo-response and conductivity of large-grained methylammonium lead iodide (MAPbI(3)) thin films are studied. In perovskite solar cells (PSC), these films result in efficiencies >17%. The grain boundaries (GBs) show high resistance at the top surface of the film, and act as an impediment to photocurrent collection. However, lower resistance pathways between grains exist below the top surface of the film, indicating that there exists a depth-dependent resistance of GBs (R-GB(z)). Furthermore, lateral conductivity measurements indicate that R-GB(z) exhibits GB-to-GB heterogeneity. These results indicate that increased photocurrent collection along GBs is not a prerequisite for high-efficiency PSCs. Rather, better control of depth-dependent GB electrical properties, and an improvement in the homogeneity of the GB-to-GB electrical properties, must be managed to enable further improvements in PSC efficiency. Finally, these results refute the implicit assumption seen in the literature that the electrical properties of GBs, as measured at the top surface of the perovskite film, necessarily reflect the electrical properties of GBs within the thickness of the film.

The polycrystalline aggregate, tuned for a low-carbon steel, is used to calculate the evolution of the yield surface during monotonic uniaxial tension. The results of the crystal plasticity model are used to train the anisotropic yield function and HAH parameters to demonstrate the flexibility of the macroscale constitutive approach. Through comparison between the two models, an improved rule for the HAH model is suggested. C1 [Jeong, Youngung] NIST, Gaithersburg, MD 20899 USA.

Enhancements of the SEP fluxes were first detected by the ACE spacecraft at 14: 00 UT, similar to 7 hours after the onset of the CME (07: 00 UT), and the SEP's peak intensities were recorded similar to 36 hours after the onset of the CME. Our recent study showed that the CME-driven shock Mach number, based on a global three-dimensional (3-D) magnetohydrodynamic (MHD) simulation, is well correlated with the time-intensity of 10-30 MeV and 30-80 MeV protons. Here we focus on the radial dependence (r(-a)) of He-4 (3.43-41.2 MeV/n) and O (7.30-89.8 MeV/n) energetic particles from ACE/SIS. It is found that the scaling factor (alpha) ranges between 2 and 4 for most of the energy channels. We also found that the correlation coefficients tend to increase with SEP energies.

Our previous numerical simulation suggested that an inflation of the heliosphere current/plasma sheet (HCS/HPS) could be the cause of the density and field anomaly [1]. The inflation of HCS/HPS hypothesizes that HCS/HPS is thicker if Sun's polar magnetic field is weaker and thinner if Sun's polar magnetic field is stronger. In this study, we provide additional evidence to support this hypothesis using photosphere magnetographs from the ground-based stations (NSO, MWO or WMO). Specifically, we compute and compare average values of the solar magnetic field for two different periods: 1995-1997 and 2007-2009. We also integrate the magnetic field over the equatorial (<7.5 degrees), the polar (47.5 degrees-87.5 degrees), and the mid-latitude (12.5 degrees-42.5 degrees) regions. It is found that at 2.5 solar radii the averaged radial-component of the magnetic field (Br) is smaller in the 2007-2009 period than in the 1995-1997 period by similar to 33% in the polar region, similar to 36% in the mid-latitude region, and similar to 11% in the equatorial region. When moving outward with the solar wind, the relatively large magnetic field at the equator may inflate the HCS/HPS at a farther distance causing the unusually low solar wind density and weak magnetic field at the equator during 2007-2009.

It is observed that the gate bias has a large effect on controlling the injection efficiency at the anode of the body diode. The change in threshold voltage due to body-effect and the voltage drop across the anode junction play a key role in controlling the balance between electron and hole currents at the anode end, which gives the device the capability to operate in unipolar, bipolar or intermediate conduction modes depending on current density and operating temperature.

Particularly, we develop a clustering-based scheme that automatically finds the best candidates to remain connected to the LTE network while the rest of the devices can be disconnected directly from the LTE-based cellular network. By doing so, we can reduce the signal interference, increase the average throughput and spectral efficiency of the network, and also reduce unnecessary data traffic that can be transmitted locally by D2D communications instead of going through the LTE-based cellular network. Devices in established clusters can indirectly communicate with the LTE network via the cluster head, which can be dynamically selected and remains connected to the LTE network directly. Using the real-world cellular data collected from a public database related to the deployment of LTE networks, we show the effectiveness of our proposed scheme in traffic offloading in the cellular network. We also discuss how to use our developed techniques to support Internet-of-Things (IoT) applications such as smart grid communications.

Due to the limitations of current intrusion detection systems and forensic analysis tools, evidence often has false positive errors or is incomplete. Additionally, because of the large number of security events, discovering an attack pattern is much like finding a needle in a haystack. Consequently, reconstructing attack scenarios and holding attackers accountable for their activities are major challenges. This chapter describes a probabilistic model that applies Bayesian networks to construct evidence graphs. The model helps address the problems posed by false positive errors, analyze the reasons for missing evidence and compute the posterior probabilities and false positive rates of attack scenarios constructed using the available evidence. A companion software tool for network forensic analysis was used in conjunction with the probabilistic model. The tool, which is written in Prolog, leverages vulnerability databases and an anti-forensic database similar to the NIST National Vulnerability Database (NVD). The experimental results demonstrate that the model is useful for constructing the most-likely attack scenarios and for managing errors encountered in network forensic analysis.

Such an instrument performance budget is a necessity for both identifying the variety of noise sources currently limiting Doppler measurements, and estimating the achievable performance of next generation exoplanet hunting Doppler spectrometers. For these instruments, no single source of instrumental error is expected to set the overall measurement floor. Rather, the overall instrumental measurement precision is set by the contribution of many individual error sources. We use a combination of numerical simulations, educated estimates based on published materials, extrapolations of physical models, results from laboratory measurements of spectroscopic subsystems, and informed upper limits for a variety of error sources to identify likely sources of systematic error and construct our global instrument performance error budget. While natively focused on the performance of the NEID instrument, this modular performance budget is immediately adaptable to a number of current and future instruments. Such an approach is an important step in charting a path towards improving Doppler measurement precisions to the levels necessary for discovering Earth-like planets.

Medical applications requirements impose stringent constraints on the reliability, and quality of service performance in these networks. Assuming CSMA/CA MAC protocol as outlined in the IEEE 802.15.6 standard Intra-BAN interference as well as interference from other co-located BANs or nearby devices sharing the same spectrum could greatly impact the data link reliability in these networks. Specifically, inter-BAN interference caused by hidden and exposed nodes could lead to higher packet delays or lower successful packet reception. In this paper, we study the use of a RTS/CTS handshake mechanism to improve the performance of IEEE 802.15.6-based CSMA/CA when multiple co-located BANs are present. Simulation results demonstrate that the introduction of RTS/CTS mechanism is able to significantly reduce packet collisions, resulting in a tangible improvement in system performance.

These neurons are connected through a network of waveguides, and variable weights of connection can be implemented using several approaches. These processing units can operate at 20 MHz with fully asynchronous activity, light-speed-limited latency, and power densities on the order of 1 mW/cm(2). The processing units achieve an energy efficiency of 20 aJ/synapse event, an improvement of six orders of magnitude over recent CMOS demonstrations [1].

TI Strong connections, loose coupling: the influence of the Bering Sea ecosystem on commercial fisheries and subsistence harvests in Alaska SO ECOLOGY AND SOCIETY LA English DT Article DE Bering Sea; commercial fisheries; ecosystem studies; human-environment connections; subsistence ID POLLOCK THERAGRA-CHALCOGRAMMA; CLIMATE-CHANGE; HUMAN DIMENSIONS; CATCH SHARES; MANAGEMENT; SCALE; COMMUNITIES; SYSTEM; ICE; CONSEQUENCES AB Human-environment connections are the subject of much study, and the details of those connections are crucial factors in effective environmental management. In a large, interdisciplinary study of the eastern Bering Sea ecosystem involving disciplines from physical oceanography to anthropology, one of the research teams examined commercial fisheries and another looked at subsistence harvests by Alaska Natives. Commercial fisheries and subsistence harvests are extensive, demonstrating strong connections between the ecosystem and the humans who use it. At the same time, however, both research teams concluded that the influence of ecosystem conditions on the outcomes of human activities was weaker than anticipated. Likely explanations of this apparently loose coupling include the ability of fishers and hunters to adjust to variable conditions, and the role of social systems and management in moderating the direct effects of changes in the ecosystem. We propose a new conceptual model for future studies that incorporates a greater range of social factors and their dynamics, in addition to similarly detailed examinations of the ecosystem itself.

TI The codevelopment of coastal fisheries monitoring methods to support local management SO ECOLOGY AND SOCIETY LA English DT Article DE adaptive management; comanagement; customary ecological knowledge; fisheries ID CORAL-REEF FISHERIES; GREAT-BARRIER-REEF; ECOLOGICAL KNOWLEDGE; SPAWNING FREQUENCY; HAWAIIAN-ISLANDS; BATCH FECUNDITY; MARINE; SYSTEMS; SIZE; CONSERVATION AB Small-scale fisheries across the globe provide critical food security, livelihoods, and human well-being, but are threatened by a combination of local and global stressors, including overexploitation, pollution, and climate change. Participatory approaches to management, especially those that incorporate local communities and customary knowledge can provide meaningful biological information that supports sustainable fisheries management and builds local adaptive capacity to changing ocean conditions. Through a collaboration between fishers, scientists, NGOs, and regulating agencies, we developed a low-cost, low-tech method to assess the seasonal spawning peaks, lunar spawning cycles, and size at maturity (L-50) for key targeted reef fish, combining traditional knowledge and practice with modern scientific approaches, including gonadosomatic index (GSI) and histology. Two years of community-based monitoring resulted in data from 57 species and 15 families of reef and nearshore fishes (n = 2595), with detailed information for 10 species at 4 locations across the Hawaiian Islands. Comparisons between community-collected GSI data and scientifically (histologically) assessed spawning cycles and size at reproductive maturity produced similar results suggesting that these approaches can be applied in data-poor fisheries to assess spawning seasons and size at maturity (L-50), both of which are critical needs for effective fisheries management. Semistructured surveys revealed a large body of local knowledge on spawning times and harvest practices based on allowing spawning to occur before harvesting and protecting small and large size classes, but little evidence that fishers understand temporal patterns of spawning. This suggests that monitoring methods that fill key gaps such as this and are congruent with these local knowledge systems and customary harvest practices may be key for local stewardship and adaptive management.

TI Estimating Hawaiian monk seal range-wide abundance and associated uncertainty SO ENDANGERED SPECIES RESEARCH LA English DT Article DE Neomonachus schauinslandi; Abundance estimation; Population trend; Monte Carlo ID MONACHUS-SCHAUINSLANDI; ISLANDS; PUPS AB The type and quantity of survey data, and consequently, applicable methods for estimating abundance, vary throughout the range of the Endangered Hawaiian monk seal Neomonachus schauinslandi. Here we present a new approach to combine disparate data and methods to estimate the range-wide abundance of this species, along with associated uncertainty. We quantified subpopulation abundance using total enumeration, closed population capture-recapture methods, empirically derived relationships between survey effort and proportion of the population detected, minimum tallies, or standardized land surveys corrected to account for seals in the water. We used a Monte Carlo approximation to generate a distribution of range-wide abundance, by summing randomly drawn values from distributions of site-specific abundance. Data to estimate range-wide abundance were available for 2013, 2014, and 2015; our estimates were 1291, 1309, and 1324 individuals, respectively. Although the point estimates increased over 2 yr, the confidence intervals for all estimates overlapped. We recognize that these estimates are subject to some varying degree of negative bias, which precludes drawing unequivocal conclusions regarding current population trends. However, after a prolonged history of population decline in this species, the lack of evidence for further decline during 2013 to 2015 is encouraging. Additional years of consistent monitoring will enable reliable assessment of the trend in total Hawaiian monk seal abundance.

TI Using Scenarios to Assess Possible Future Impacts of Invasive Species in the Laurentian Great Lakes SO NORTH AMERICAN JOURNAL OF FISHERIES MANAGEMENT LA English DT Article ID LONG-TERM TRENDS; FOOD-WEB; ECOSYSTEM SERVICES; LARGEMOUTH BASS; ILLINOIS RIVER; NORTH-AMERICA; ASIAN CARPS; GRASS CARP; RISK; HURON AB The expected impacts of invasive species are key considerations in selecting policy responses to potential invasions. But predicting the impacts of invasive species is daunting, particularly in large systems threatened by multiple invasive species, such as North America's Laurentian Great Lakes. We developed and evaluated a scenario-building process that relied on an expert panel to assess possible future impacts of aquatic invasive species on recreational fishing in the Great Lakes. To maximize its usefulness to policy makers, this process was designed to be implemented relatively rapidly and considered a range of species. The expert panel developed plausible, internally consistent invasion scenarios for five aquatic invasive species, along with subjective probabilities of those scenarios. We describe these scenarios and evaluate this approach for assessing future invasive species impacts. The panel held diverse opinions about the likelihood of the scenarios, and only one scenario with impacts on sport fish species was considered likely by most of the experts. These outcomes are consistent with the literature on scenario building, which advocates for developing a range of plausible scenarios in decision-making because the uncertainty of future conditions makes the likelihood of any particular scenario low. We believe that this scenario-building approach could contribute to policy decisions about whether and how to address the possible impacts of invasive species. In this case, scenarios could allow policy makers to narrow the range of possible impacts on Great Lakes fisheries they consider and help set a research agenda for further refining invasive species predictions.

Dynamic Programming (DP) is an effective approach to solve this problem. In this paper, we propose a DP algorithm that runs in O(N) time to compute optimal diffeomorphisms for elastic registration of curves with N nodes. This algorithm contrasts favorably with other DP algorithms used for this problem: the commonly used algorithm of quadratic time complexity, and the algorithm that guarantees a globally optimal solution with O(N-4) time complexity. Key to our computational efficiency is the savings achieved by reducing our search space, focusing on thin strips around graphs of estimates of optimal diffeomorphism. Estimates and strips are obtained with a multigrid approach: an optimal diffeomorphism obtained from a lower resolution grid using DP is progressively projected to ones of higher resolution until full resolution is attained. Additionally, our DP algorithm is designed so that it can handle nonuniformly discretized curves. This enables us to realize further savings in computations, since in the case of complicated curves requiring large numbers of nodes for a high-fidelity representation, we can distribute curve nodes adaptively, focusing nodes in parts of high variation. We demonstrate effectiveness of our DP algorithm on several registration problems in elastic shape analysis, and functional data analysis.

By superimposing known background noise with high quality images in various proportions, we produce a degraded image set spanning a range of SNRs with reference feature values established from the unmodified high quality images. We then experiment with a variety of image processing spatial filters applied to the degraded images and identify which filter produces an image whose feature values most closely correspond to the reference values. When using the best combination of three filters and six kernel sizes for each feature, the average correlation of feature values between the degraded and high quality images increased from 0.6 (without filtering) to 0.92 (with feature-specific filters), a 53% improvement. Selecting a single filter is more practical than having a separate filter per feature. However, this results in a 1.95% reduction in correlation and a 10% increase in feature residual root mean square error compared to selecting the optimal filter and kernel size per feature. We quantified the tradeoff between a practical solution for all features and feature-specific solution to support decision making.

We project 2D calibration patterns onto 3D finger surfaces pertaining to each of the four fingers and the thumb to synthetically generate electronic 3D whole hand targets. A state-of-the-art 3D printer is then used to fabricate physical 3D hand targets with printing materials that are similar in hardness and elasticity to the human skin and are optically compatible for imaging with a variety of fingerprint readers. We demonstrate that the physical 3D whole hand targets can be imaged using three commercial (500/1000 ppi) Appendix F certified contact-based slap fingerprint readers and a PIV certified contactless slap reader. We further show that the features present in the 2D calibration patterns (e.g. ridge structure) are replicated with high fidelity on both the electronically generated and physically fabricated 3D hand targets. Results of evaluation experiments for the three contact-based slap readers and the contactless slap reader using the generated whole hand targets are also presented. This study, for the first time, demonstrates the utility of the 3D wearable hand targets for evaluation of slap readers, both contact and contactless.

Significant MIDLIIS events are revealed in Regional or Global maps of ionospheric irregularities and scintillation (RMIIS and GMIIS [1][2]). GMIIS are produced using GPS measurements from thousands of globally distributed stations. We intend to add MIDLIIS as a new element to the classical picture of global ionospheric scintillation and irregularities because the observed MIDLIIS events occurred in vast regions. To understand underlying physics mechanisms, the MIDLIIS development is compared with space weather conditions and geomagnetic data as well as auroral observations made by global ultraviolet imager (GUVI) onboard a Defense Meteorology Satellite Program (DMSP) satellite. The GUVI images show auroral oval expansion when MIDLIIS are observed. Our study leads to an assessment that MIDLIIS events are driven by auroral oval expansion to middle latitudes and possible ring current inward expansion to the plasmasphere with associated penetration of the magnetospheric electric field. Before presenting the MIDLIIS investigation, measurements of ionospheric scintillation and irregularities, namely S-4, sigma(phi), and ROTI, are reviewed. A comparison is made to distinguish differences and emphases between these indices. C1 [Pi, Xiaoqing] CALTECH, Jet Prop Lab, NASA, 4800 Oak Grove Dr, Pasadena, CA 91125 USA.

Most studies of artificial spin ice focus on two lattice geometries, the square and the kagome lattices, due to their direct correspondence to natural spin ice materials such as Dy2Ti2O7. In this work, we review experiments on these more unusual lattice geometries and introduce a new type of nanomagnet array, artificial spin glass. Artificial spin glass is a two-dimensional array of nanomagnets with random locations and orientations and is designed to elucidate the more complex frustration found in spin glass materials.

Solving a diffusive spin-transport theory with appropriate boundary conditions gives an analytical formula of the longitudinal charge current density. The longitudinal charge current has a term that is proportional to the square of the spin-transfer torque efficiency and that also depends on the ratio of the film thickness to the spin diffusion length of the ferromagnet. Extracting this contribution from measurements of the longitudinal resistivity as a function of the thickness can give the spin-transfer torque efficiency.

Even with outstanding performances in both energy (similar to eV on keV) and time resolution (similar to 1 mu s) on the single channel, a large number of detectors working in parallel is required to reach a sub-eV sensitivity. HOLMES is a new experiment to directly measure the neutrino mass with a sensitivity as low as 2 eV. HOLMES will perform a calorimetric measurement of the energy released in the electron capture (EC) decay of Ho-163. In its final configuration, HOLMES will deploy 1000 detectors of low temperature microcalorimeters with implanted 163Ho nuclei. The baseline sensors for HOLMES are Mo/Cu TESs (Transition Edge Sensors) on SiNx membrane with gold absorbers. The readout is based on the use of rf-SQUIDs as input devices with flux ramp modulation for linearization purposes; the rf-SQUID is then coupled to a superconducting lambda/4-wave resonator in the GHz range, and the modulated signal is finally read out using the homodyne technique. The TES detectors have been designed with the aim of achieving an energy resolution of a few eV at the spectrum endpoint and a time resolution of a few micro-seconds, in order to minimize pile-up artifacts.

To address this issue, the National Institute of Standards and Technology (NIST) initiated the Global City Teams Challenge (GCTC) to catalyze collaboration among different stakeholders. The goal is to design and deploy IoT and smart city solutions that are replicable, scalable, and sustainable, thereby leading to the identification and adoption of a consensus framework for smart city technologies. The second round of GCTC is currently in its first phase. Future smart city projects would benefit from a widely distributed IoT communications fabric that can serve as an infrastructure for the deployment of truly sharable and replicable smart city solutions.

Medical applications impose stringent requirements on BAN Quality of Service (QoS), including reliability and on-time availability of data. However, interference from other co-located BANs or other nearby devices sharing the same spectrum, e.g., due to BAN mobility, may cause unacceptable QoS degradation. This paper suggests that the impact of such QoS degradations can be minimized with a queue-size and channel quality based adaptation of the Energy Detection Threshold (EDT) at the transmitting nodes. Guided by known results for QCSMA/CA, we propose an adaptive EDT algorithm for use in the IEEE 802.15.6 BAN standard. Our preliminary simulation results demonstrate the performance gain of our algorithm compared to using a fixed EDT, and thus warrant future efforts in the adaptive EDT optimization as a mechanism to maintain QoS in various interference scenarios.

Simple bugs, which involve only direct factors and are often easy to reproduce, have been called "Bohrbugs", while complex bugs, with at least one indirect factor and generally much more difficult to reproduce, were called Mandelbugs. Locating Mandelbugs in software is often difficult and expensive during the development phase due to their complexity. In this paper we consider the relationship between different types of software bugs and the average t-way interaction involved in triggering them. Analysis suggests that Mandelbugs have a higher interaction strength when triggering their faults. This suggests that both direct and indirect factors play a role in triggering the fault. By using combinatorial testing methods, we can have high assurance of locating Mandelbugs as long as the indirect factors are present at the time of testing.

Medical applications requirements impose stringent constraints on the reliability, and quality of service (QoS) in these networks. Radio interference from other co-located BANs or nearby devices that share the same spectrum could greatly impact the data link reliability in these networks. The CSMA/CA MAC protocol as outlined in the IEEE 802.15.6 BAN standard involves the use of an Energy Detection (ED) threshold to determine the status of the transmission channel i.e. idle versus busy. In our previous work, we have shown that the use of such static thresholds negatively impacts the performance of the system composed of multiple co-located BANs, leading to possible starvation or unfair treatment for several nodes. This paper proposes low complexity schemes that can be used to adapt the ED threshold in transmitting nodes of a BAN. The objective is to fairly allow channel access to all nodes regardless of the level of interference that they are experiencing. Simulation results indicate benefits of the proposed strategy and demonstrate improvement in the overall performance.

This paper provides an update on a joint project employing commercial equipment to send national timing signals through a telecommunication network in the United States. This experiment connects the UTC(NIST) time scale located in Boulder, Colorado with the UTC(USNO) Alternate Master Clock time scale located at Schriever Air Force Base in Colorado via a telecommunication provider's optical network. Timing signals using the Precision Time Protocol (PTP) were sent in the usual two-way fashion, but each one-way delay was measured, because we had UTC time scales at both ends of the network that were within 10 ns of each other. This part of the experiment is now nearly complete. The experiment was started in April 2014 and extensions of the project will run through the end of 2016. It appears that there is at least one commercial transport mechanism that could serve to back up GPS for time transfer at the 100 ns level. We found that the asymmetry of the PTP time transfer resulted in 10's of microseconds of time transfer error, but that the stability through the entire connection was less than 100 ns, as long as the connection remained complete. This implies that if the time delays of the network could be calibrated, it could maintain under 100 ns accuracy as long as it did not go down. We have established the likely causes of the bias, as well as run simulations of various configurations in a laboratory. Thus, we have some certainty that similar results will apply if this technique were used as a service across the country. While many researchers have shown that fiber can transfer time and frequency with high accuracy, this experiment addresses the practicality of using the US telecom infrastructure for timing.

In the present study, we investigated the defense mechanisms of Arabidopsis thaliana in response to 250 mg L-1 and 1000 mg L-1 cerium oxide (CeO2) and indium oxide (In2O3) NPs exposure. Excessive amounts of total reactive oxygen species (ROS) were measured upon exposure to both NPs, demonstrating clear oxidative stress in Arabidopsis. Analysis of ROS scavenger activity indicated that activities of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and peroxidase (POD) were significantly elevated upon exposure to CeO2 NPs, while these elevations were only evident for SOD and POD activities in the In2O3 NP treatments. In addition, the activities of glutathione S-transferase (GST) and glutathione reductase (GR) were increased by approximately 15% and 51% by 1000 mg L-1 CeO2 and In2O3 treatment, respectively. Furthermore, the activities of phenylanine ammonialyase (PAL) and polyphenol oxidase (PPO) were greatly induced in response to both types of NPs. Additionally, both NPs disrupted the uptake of elemental nutrients, as is evident from the significantly lower levels of Fe accumulation in Arabidopsis root tissues exposed to CeO2 and In2O3 NPs. These results were further supported by the differential regulation of three iron-regulating genes, including ferric chelate reductase (FRO), iron-regulated transporter (IRT) and ferritin (FER), at various time points. The findings provide useful mechanistic information for plant detoxification pathways following NP exposure.

For this purpose, we designed and built a minimum-deviation-angle refractometry system enabling diffraction-limited index measurements for wavelengths from 0.12 mu m to 14 mu m. We discuss the apparatus and procedures that we use for IR measurements. First results are presented for germanium for the wavelength range from 2 mu m to 14 mu m, with standard uncertainties ranging from 2 x 10(-5) near 2 mu m to 8 x 10(-5) near 14 mu m. This is an improvement by about an order of magnitude of the uncertainty level for index data of germanium generally used for optic design. A Sellmeier formula fitting our data for this range is provided. An analysis of the uncertainty is presented in detail. These measurements are compared to previous measurements of Ge.

Faulty policies, misconfigurations, or flaws in software implementations can result in serious vulnerabilities. To formally and precisely capture the security properties that access control should adhere to, access control models are usually written, bridging the gap in abstraction between policies and mechanisms. Identifying discrepancies between policy specifications and their intended function is crucial because correct implementation and enforcement of policies by applications is based on the premise that the policy specifications are correct. As a result, policy specifications represented by models must undergo rigorous verification and validation through systematic verification and testing to ensure that the policy specifications truly encapsulate the desires of the policy authors. Verifying the conformance of access control policies and models is a non-trivial and critical task, and one important aspect of such verification is to formally check the inconsistency and incompleteness of the model and safety requirements of the policy, because an access control model and its implementation do not necessarily explicitly express the policy, which can also be implicitly embedded by mixing with direct access constraints or other access control models.

In particular, the long recovery time of single -photon detectors and large channel noise at long distance both limit the rate at which a final secure key can be generated in a low-dimension QKD system. We propose and demonstrate a practical discrete-variable time-frequency protocol with d = 4 at a wavelength of 1550 nm, where the temporal states are secured by transmitting and detecting their dual states under Fourier transformation, known as the frequency -basis states, augmented by a decoy-state protocol. We show that the discrete temporal and frequency states can be generated and detected using commercially-available equipment with high timing and spectral efficiency. In our initial experiments, we only have access to detectors that have low efficiency (1%) at 1550 nm. Together with other component losses, our system is equivalent to a QKD system with ideal components and a50-km-long optical-fiber quantum channel. We find that our system maintains a spectral visibility of over 99.0% with a quantum bit error rate of 2.3%, which is largely due to the finite extinction ratio of the intensity modulators used in the transmitter. The estimated secure key rate of this system is 7.7 x 10(4) KHz, which should improve drastically when we use detectors optimized for 1550 nm.

This has happened as a consequence of the development of new and powerful numerical methods, translating these algorithms into practical software and the associated evolution of powerful computing platforms ranging from desktops to high performance computational instruments capable of massively parallel computation. We are taking the opportunity afforded by this CCP2015 to review computational progress in scattering theory and the interaction of strong electromagnetic fields with atomic and molecular systems from the early 1960's until the present time to show how these advances have revealed a remarkable array of interesting and in many cases unexpected features.

Economics drives two major evolutionary trends in networked system design/operation: (a) towards the boundary of the system capacity/operational region, where all system resources are fully utilized, and (b) an increase in the system interconnectivity allowing enlargement of this region due to dynamic resource sharing. However, numerous recent systemic failures in various performance oriented networked systems demonstrated systemic risks associated with these trends. Using the "Complex System" perspective, we associate the systemic risks with a possibility of system phase transition to an undesirable persistent state. Specifically, we argue that while growing interconnectivity allows a system to accommodate "small" demand/capacity imbalances, sufficiently large imbalances may result in abrupt/discontinuous instabilities, which is a form of "robust yet fragile" phenomenon. Motivated by higher performance losses and lower predictability of abrupt/discontinuous vs. gradual/continuous systemic overload, the proposed "systemic risk aware performance engineering," intends to enlarge the system capacity/operational region subject to ensuring gradual/continuous system performance deterioration once the boundary of the system operational region is breached.

We prove a (3 + 1/86)n - o(n) lower bound on the size of such a circuit for an explicitly defined predicate, namely an affine disperser for sublinear dimension. This improves the 3n - o(n) bound of Norbert Blum (1984). The proof is based on the gate elimination technique extended with the following three ideas. We generalize the computational model by allowing circuits to contain cycles, this in turn allows us to perform affine substitutions. We use a carefully chosen circuit complexity measure to track the progress of the gate elimination process. Finally, we use quadratic substitutions that may be viewed as delayed affine substitutions.

For their safe integration into the worldwide airspace, reliable control and non-payload communication (CNPC) systems must be developed. The performance of any CNPC system depends critically upon the characteristics of the air-ground (AG) channel. Hence the authors, supported by NASA Glenn Research Center, gathered data from an air-ground measurement campaign explicitly aimed at characterizing this channel in two bands recently allocated for UAS, the L- and C-bands. The measurements were conducted in 2013, and produced the largest set of AG channel data ever gathered to date. This data, for seven ground site (GS) environments, was subsequently processed to develop models for the AG channel's characteristics. In this paper we summarize the measurement campaign, measurement results, and completed models for propagation path loss, small-scale fading, airframe shadowing, wideband multipath characteristics, and correlations among the channel effects on two antennas and in the two bands. Path loss in the line-of-sight (LOS) AG channels generally follows that of free-space, but with significant two-ray attenuation peaks (exceeding 18 dB) recorded for relatively smooth earth surfaces. Small-scale fading was found to be well-modeled as Ricean, with K-factors on the order of 12 dB for L- and, 28 dB for C-band. Airframe shadowing was also found to be potentially severe, yielding attenuations of larger than 30 dB for both bands. As expected in the LOS conditions, channels were highly correlated for signals in the same band, but essentially uncorrelated between the two bands. Wideband models contain from one to seven intermittent multipath components, with power levels similar to 20 dB down from that of the LOS component; these yield root-mean square delay spreads up to similar to 2 microseconds. These results have been incorporated into the Radio Technical Commission for Aeronautics (RCTA)'s Special Committee (SC)-228 work on UAS, and should be of use to future designers and developers of UAS communication systems.

The quality and validation of these measurements using the approved analytical methodology could be significantly enhanced by incorporating certified reference materials as part of the quality control protocols, yet this has not been widely implemented. Data from certified reference materials can provide critical information that can impact assessments regarding data use that is unavailable by other means. Using the analysis of Cr(VI) in soil extracts as the test case, some of the issues surrounding the use of certified reference materials for environmental applications are discussed in this paper, including the relative cost, and the availability and applicability regarding element coverage and content.

The aromatic character was calculated using a method that combines the pi-Sextet Rule and the Pauling Ring Bond Orders to allow the establishment of the location and migration of aromatic sextets in PAH structures. One GC column with a polysiloxane-like backbone (Rxi-PAH) and three GC columns with a polysiloxane backbone (DB-5, SE-52 and LC-50) were used for the analysis. According to the results of this study, within an isomer group, PAHs that contain a lower number of rings affected by the aromatic sextets tend to elute earlier than PAHs that contain a higher number of rings affected by the aromatic sextets. The PAHs that follow the calculated elution order are 88% in the Rxi-PAH column, 88% in the DB-5 column, 93% in the SE-52 column and 85% in the LC-50 column. It is expected that future analyses with other aromatic compounds in GC columns with a polysiloxane backbone in the stationary phase will follow a GC elution order that agrees with the aromatic character of the molecules.

NIST is pioneering a new approach based on an off-the-shelf, industrial six-degrees-of-freedom, articulated-arm robot.

This paper's contribution is twofold. First, it derives the relevant Quality of Service (QoS) communication requirements and proposes the corresponding overall performance criterion for the communication network, which quantifies the negative effect of delaying energy pricing information on the grid operations. Second, this paper demonstrates that the conventional Network Utility Maximization (NUM) based cross-layer optimization framework can be enhanced to incorporate the specific requirements of the smart power grid infrastructure. The conventional NUM based cross-layer network optimization balances tradeoffs between bandwidth requirements of multiple users, given limited network resources. The proposed enhanced NUM also allows the system to balance user requirements for (a) communication reliability by taking advantage of multipath routing in presence of network outages, and (b) communication delays by taking advantage of priority packet scheduling. Future research should quantify advantages of the proposed robust and QoS-aware NUM as compared to the conventional NUM for specific operation scenarios of the smart power grid infrastructure.

Thousands of PMUs deployed in the North American power grid are supplied by a number of different PMU vendors. Synchrophasor data exchange, sharing and interoperability are major challenges for the power industry. Interoperability testing is one of solutions to assure PMU data interoperability. This paper proposes an interoperability test method for IEEE C37.118 standard-based PMUs. An interoperability test system provided in this paper consists of five parts: a PMU tester, device under test (DUT) (PMU), a network switch, a network sniffer and a PMU interoperability analyzer. IEEE C37.118-2005 provides five test cases. Five test cases of eight commercial PMUs from different vendors have been tested with the PMU Tester over Ethernet. One interoperability test case is described in detail. The interoperability test results of five test cases for each PMU have been provided.

Automatic methods for quantitative assessment of a latent in terms of (i) value for individualization (VID), (ii) value for exclusion only (VEO), and (iii) no value (NV), are needed to minimize the workload of latent examiners so that they can pay more attention to challenging prints (VID and NV latents). Current value determination is either made by examiners or predicted given manually annotated features. Because both of these approaches depend on human markup, they are subjective and time consuming. We propose a fully automatic method for latent value determination based on the number.; reliability, and compactness of the minutiae, ridge quality, ridge flow, and the number of core and delta points. Given the small number of latents with VEO and NV labels in two latent databases available to us (NIST SD27 and WVU), only a two-class value determination is considered, namely VID and (VID) over bar, where the (VID) over bar class contains VEO and NV latents. Experimental results show that the value determination by the proposed method (i) obviates the need for examiner markup while maintaining the accuracy of value determination and (ii) can predict the AFIS performance better than examiners.

Time is the common entity that computing and physical systems in CPS share, and correct interfacing of that is essential to flawless functionality of a CPS. Fundamental research is needed on ways to synchronize clocks of computing systems to a high degree, and on design methods that enable building blocks of CPS to perform actions at specified times. To realize the potential of CPS in the coming decades, suitable ways to specify distributed CPS applications are needed, including their timing requirements, ways to specify the timing of the CPS components (e.g. sensors, actuators, computing platform), timing analysis to determine if the application design is possible using the components, confident top-down design methodologies that can ensure that the system meets its timing requirements, and ways and methodologies to test and verify that the system meets the timing requirements. Furthermore, strategies for securing timing need to be carefully considered at every CPS design stage and not simply added on. This paper exposes these challenges of CPS development, points out limitations of previous approaches, and provides some research directions towards solving these challenges.

TI Domestic and imports sources of supply to the US shrimp market and anti-dumping duties SO JOURNAL OF ECONOMIC STUDIES LA English DT Article DE Acquaculture; Anti-dumping duties; Domestic supply; Downward-slopping supply; Shrimp imports ID TAXI DRIVERS; LABOR; SEASONALITY; SUBSISTENCE; INTEGRATION; CURVE; TIME AB Purpose - The purpose of this paper is to provide an economic analysis of the sources of supply to the US shrimp market. Design/methodology/approach - The paper uses monthly time series data to estimate a simultaneous equations model with equations for domestic supplies from the Gulf of Mexico, imports, and prices. Findings - Estimated long-run elasticities suggest that the domestic shrimp supply appears to be explained by seasons, diesel fuel price, hurricane activity, and shrimp price. The authors find evidence of a downward-slopping supply curve for the domestic harvesters that is likely to be temporary. Furthermore, anti-dumping duties have been ineffectual in curtailing imports produced by exploitation of natural shrimp biomass in developing countries and by technological advancements in aquaculture production. The authors also find evidence of a low exchange rate pass through. Finally, while domestic and import prices are not cointegrated, there is a two-way causality between them. Practical implications - The authors found evidence that shrimp prices have fallen as import supply, due to technological advances in aquaculture, has risen faster than the US domestic demand over time suggesting a downward sloping supply curve. Also, the falling value of the US dollar has discouraged the imports, while the anti-dumping duties appear to have had little influence on the aggregate level of imports. Originality/value - It provides a thorough investigation of the supply side of an important component of the US seafood market displaying the complexity of domestic producers' reaction to falling prices, and ineffectual protectionism.

The new correlation was used to compare the heat transfer coefficient of the three test fluids at the same heat flux, saturated refrigerant temperature, and refrigerant mass flux. The resulting comparison showed that refrigerant R452B exhibited the highest heat transfer, in large part due to its approximately 28% larger liquid thermal conductivity and smaller temperature glide as compared to the tested low-global warming potential refrigerants. For the example case, the heat transfer coefficient for R449A was approximately 8% larger than that for R448A, while the heat transfer coefficient for R452B was more than 59% larger than either R448A or R449A. The heat transfer coefficients for R448A and R449A were roughly between 26 and 48% less than that of R404A for the example case. In contrast, the model predicts that the R452B heat transfer coefficient was approximately 13% larger than that of R404A for the same conditions.

One of the key instruments under study is an X-ray microcalorimeter, and the requirements for such an instrument are currently under discussion. In this paper we review some different detector options that exist for this instrument, and discuss what array formats might be possible. We have developed one design option that utilizes either transition-edge sensor (TES) or magnetically coupled calorimeters (MCC) in pixel array-sizes approaching 100 kilo-pixels. To reduce the number of sensors read out to a plausible scale, we have assumed detector geometries in which a thermal sensor such a TES or MCC can read out a sub-array of 20-25 individual 1" pixels. In this paper we describe the development status of these detectors, and also discuss the different options that exist for reading out the very large number of pixels.

The instrument will provide unprecedented spectral resolution of similar to 2.5 eV at energies of up to 7 keV and will accommodate photon fluxes of 1 mCrab (90 cps) for point source observations. The baseline configuration is a uniform large pixel array (LPA) of 4.28" pixels that is read out using frequency domain multiplexing (FDM). However, an alternative configuration under study incorporates an 18 x 18 small pixel array (SPA) of 2" pixels in the central similar to 36" region. This hybrid array configuration could be designed to accommodate higher fluxes of up to 10 mCrab (900 cps) or alternately for improved spectral performance (< 1.5 eV) at low count-rates. In this paper we report on the TES pixel designs that are being optimized to meet these proposed LPA and SPA configurations. In particular we describe details of how important TES parameters are chosen to meet the specific mission criteria such as energy resolution, count-rate and quantum efficiency, and highlight performance trade-offs between designs. The basis of the pixel parameter selection is discussed in the context of existing TES arrays that are being developed for solar and x-ray astronomy applications. We describe the latest results on DC biased diagnostic arrays as well as large format kilo-pixel arrays and discuss the technical challenges associated with integrating different array types on to a single detector die.

The XAFS Data Interchange (XDI) standard is meant to encapsulate a single spectrum of XAFS along with relevant metadata. XDI is a text-based format with a simple syntax which clearly delineates metadata from the data table in a way that is easily interpreted both by a computer and by a human. The metadata header is inspired by the format of an electronic mail header, representing metadata names and values as an associative array. The data table is represented as columns of numbers. This format can be imported as is into most existing XAFS data analysis, spreadsheet, or data visualization programs. Along with a specification and a dictionary of metadata types, we provide an application-programming interface written in C and bindings for programming dynamic languages.

NPG glasses are promising candidates for applications in nonlinear optical devices because they exhibit interesting optical characteristics such as high nonlinear third order optical susceptibility. In this work NPG glasses were prepared with pulsed laser deposition method with varying oxygen partial pressure to induce thin films with different oxygen stoichiometry. Previously, it was shown that oxygen stoichiometry has a very important effect to produce unusual high optical susceptibility. Detailed EXAFS and XANES analyses in a series of NPG thin films revealed the subtle variations in the local environment around Nb atoms and the Nb oxidation states caused by oxygen deficiencies.

Alteration in hydrogen bonding at the amino group leads to a shift to high energy for both the XPS N 1s core level and the 3 pi* NEXAFS resonance with beta-PABA. Participation of the amine group in the aromatic system causes the 1 pi* resonance to be sensitive to the nature of the intermolecular bonding at the para-carboxylic acid group, and a shift to low energy for alpha-PABA is observed due to hydrogen-bonded carboxylic acid dimer formation. FEFF calculations also successfully reproduce both the energy and intensity variations observed for the sigma* shape resonance associated with the C-N bond, with the majority of the decrease in energy observed for beta-PABA arising from the longer C-N bond.

Existence of systemic risks in economically incentivized networked systems is demonstrated by recent numerous systemic failures in various critical large-scale networked infrastructures. Using "Complex System" perspective, we consider systemic risks due to overload experienced by a sizable portion of the network. Economic pressures facilitate systemic overload by incentivizing (a) high level of dynamic resource sharing allowing the system to mitigate effects of inherently uncertain exogenous demand and limited system reliability, and (b) network operation on the stability boundary where all network resources are fully utilized. However, in practice these economic incentives are counteracted by bounded rationality of the network operator(s), e.g., due to limited information on the uncertain exogenous environment. We argue that bounded rationality reduces both the network operational region and risk of abrupt overload. Due to higher performance losses and lower predictability of a discontinuous/abrupt overload as compared to a continuous/gradual one, our results suggest that bounded rationality may benefit the system performance by allowing system to operate closer to the stability boundary.

This framework includes both explicit and implicit (sensorbased) registration techniques using as few as three reference poses per robot, and presents different methods for measuring registration uncertainty. Driven by the guiding principles of simplifying the registration process to enable rapid installation by non-expert users, a mathematical basis for fast system registration is presented. We also present methods for quickly and inexpensively approximating the registration errors, and outline mechanisms for improving registration performance. Several case study examples are provided in which the registration performance is captured across four different registration methods, and two different robots. A reference motion capture system is used to capture post-registration positioning accuracy of the robots, a sampling-based registration estimation technique is assessed, and results are systematically quantified.

Here we demonstrate the general capability to image electronic variations within nanomaterials using nanowires of VO2 and Si as model systems. For VO2 we image the temperature-dependent metal-insulator domain coexistence that arises due to the built-in strain in substrate-clamped wires. In Si NWs integrated into a transistor device architecture we observe large increases in the source-drain current with the tip passing over the wire, correlated with variations in the SMM signal. We attribute this effect to local rectification of the microwave signal by the local tip-sample Schottky junction.

In both of these cases, thermal gradients can present a significant source of uncertainty. In the astronomy community, SIS mixers biased beyond their gap voltage are often used as shot-noise sources and employed to determine the noise of IF amplifiers. In this work, a tunnel junction with metal electrodes is used as noise source for characterization of cryogenic amplifiers. It is shown that this method is easily calibrated and can provide results that agree well with those obtained using the cold-attenuator method.

Two quantitative methods were developed to compare the inter-pulse sound field, defined as the acoustic field between two consecutive airgun pulses, with the ambient noise level. Results show that during periods when seismic airguns were active, inter-pulse sound field could exceed ambient noise levels by as much as 9 dB. Kolmogorov-Smirnov two-sample tests between inter-pulse sound levels and ambient noise levels showed significant differences in median SPLs. Spectral analysis of inter-pulse sound fiend in one-third-octave bands in relation with known and hypothetical marine mammal hearing sensitivities indicates potential acoustic masking during a seismic survey, even for animals at relative far distances from a survey vessel. Degrees of acoustic masking are related to frequency-depended hearing sensitivities of marine mammals. For the endangered bowhead whales, which are most sensitive to low-frequency sounds, acoustic masking is expected to be most severe as most energy from seismic airgun pulses is below 500 Hz. These results underscore the need for further research on reverberant field of marine seismic surveys and its potential impacts on marine animals.

Due to the integral role of the networking infrastructure, such systems are vulnerable to cyber attacks. In-depth consideration of security and resilience and their effects to system performance are very important. This paper focuses on railway control systems (RCS), an important and potentially vulnerable class of ICS, and presents a simulation integration platform that enables (1) Modeling and simulation including realistic models of cyber and physical components and their interactions, as well as operational scenarios that can be used for evaluations of cybersecurity risks and mitigation measures and (2) Evaluation of performance impact and security assessment of mitigation mechanisms focusing on authentication mechanisms and firewalls. The approach is demonstrated using simulation results from a realistic RCS case study.

However, limitations of the survey vehicle must be considered when developing methods. To that end, we estimated densities of demersal fishes from 28 paired strip-transect surveys, using a manned submersible (a human-occupied vehicle, HOV) and a remotely operated vehicle (ROV) in 3 types of habitats (high-relief rock, low-relief mixed rock, and soft sediments) at water depths of 75-315 m off central California. Differences in fish detection, identification, and measurements were observed between vehicles (e.g., densities of unidentified fishes, unidentified rockfishes, and unidentified species of Sebastomus were significantly higher in ROV surveys). Species most closely associated with the seafloor were observed at higher densities in HOV surveys than in ROV surveys-a result possibly due to the greater reactions of fish to the ROV. The percentage of fish for which we could not estimate size was greater from video images collected with the ROV than from in situ observations made from the HOV. Results of our study will be useful for evaluation of the limitations and biases of these survey vehicles in assessments of demersal fishes.

Length at 50% reproductive maturity was estimated as 19.6 cm fork length (FL) for females and as 18.7 cm FL for males for the corresponding ages of 2.6 and 2.4 years. Available data from several sources for this data-poor coral reef fish were analyzed to assess its population status in Saipan Lagoon, Northern Marianna islands. Estimates of total mortality (Z) within the period 2005-2011 were derived by using length-converted catch-curve analysis and the Chapman-Robson estimator. Natural mortality (M) was estimated from 3 models based on applicable observations and parameter estimates derived from data for thumbprint emperor in Saipan Lagoon. Exploitation ratios (E) derived with combinations of Z and M estimators within the period 2005-2011 showed a wide disparity, although no estimate of average annual E exceeded 0.5 (an E over that threshold would have indicated overexploitation). Location-specific life history studies should be pursued to support local research and management goals. Standardized methods for the estimation of life history parameters would allow empirical comparisons between regions.

We tagged 8 dolphinfish with pressure-sensitive ultrasonic transmitters and actively tracked individuals continuously for up to 40 h to elucidate the vertical movement patterns and differences between FADassociated (FAD-A) and FAD-unassociated (FAD-U) fish. Four additional fish were equipped with acoustic transmitters and passively monitored for several days with receivers attached to FADs. When not associated with FADs, dolphinfish used the upper 75-100 m of the water column during the day and made descents up to 160 m during the night. In contrast, FAD-A fish generally stayed within the upper 10 m of the water column and tended to make deeper excursions during the day rather than at night. Water temperature data from expendable bathythermo-graphs deployed during active tracking showed that fish only descended to depths where temperatures were <= 3 degrees C cooler than the uniform-temperature surface layer. The use of vertical behavior to determine whether a dolphinfish is associated or not with a floating object opens the possibility for new, large-scale research aimed at investigating the role of floating objects in the ecosystem inhabited by this species and at assessing the impacts of FADs on its ecology.

TI Evaluating the vulnerability of an atypical protogynous hermaphrodite to fishery exploitation: results from a population model for black sea bass (Centropristis striata) SO FISHERY BULLETIN LA English DT Article ID GULF-OF-MEXICO; CHANGING FISH; ANIMALS; MANAGEMENT; EVOLUTION; ATLANTIC AB Fish species that are protogynous hermaphrodites generally have sex ratios skewed toward males at large sizes. These skewed sex ratios at length can make a stock more vulnerable to overexploitation, particularly in fisheries where minimum size is regulated, resulting in the removal of reproductively active males. We developed a length-based population model to test the vulnerability to exploitation of a population with an atypical protogynous life history, in particular the northern stock of black sea bass (Centropristis striata). Black sea bass north of Cape Hatteras, North Carolina, are unusual for protogynous species in that they may undergo prematurational transformation, remain female at large sizes, involve secondary males in spawning, and undertake seasonal migrations. The model was developed to examine the impact of participation by secondary males in population productivity, the influence of size at sex transformation, and the subsequent robustness of the population under exploitation, in comparison with equivalent gonochoristic and typical protogynous populations. Although the model does not capture all the dynamics of a population, such as density-dependent regulation of sex transformation, our results indicate that the northern stock of black sea bass may be more resilient in response to exploitation than would be expected if they were typical protogynous hermaphrodites.

Herein we report the hydrogen storage performances of the KSiH3 phase ball-milled with NbF5 as a catalyst. The kinetics of hydrogen absorption/desorption are strongly enhanced by the addition of a catalyst as revealed by the large decrease of activation energies for both the absorption and desorption reactions. No disproportionation phenomenon is observed, indicating that the reaction between KSiH3 and KSi is perfectly reversible with a hydrogen storage capacity of 4.1 wt% H-2. The thermodynamic properties of this KSi/KSiH3 equilibrium were investigated by plotting PCI curves from 90 degrees C to 130 degrees C: an enthalpy of 24.3 kJ mol(-1) H-2 and a low entropy change of 59.5 J K-1 mol(-1) H-2 are found. This low entropy variation is related to the high mobility of the H atoms in the alpha-KSiH3 phase as recently demonstrated by Quasi-Elastic Neutron Scattering (QENS) experiments.

We sampled shallow shoreline and deeper main-stem channel habitats in the Columbia River estuary over 3 years to compare salmon species composition, migration timing, density, size, and production type (hatchery or natural). Results indicated a high degree of spatial heterogeneity in habitat occupancy by the five salmonid species that are native to the basin. Salmonid communities at two channel habitat sites were much more similar to each other than to the community at a shoreline site. Salmonids sampled at the shoreline site were primarily subyearling Chinook Salmon Oncorhynchus tshawytscha and Chum Salmon O. keta and yearling Coho Salmon O. kisutch, with few other salmonids present. In contrast, channel habitat contained a higher diversity of salmon species, with samples representing all species of anadromous salmonids, including Sockeye Salmon O. nerka and steelhead O. mykiss. Salmonids in deeper channel habitat were generally larger than salmonids found along the shore, and the proportion of hatchery-origin salmon was also higher in deep channel habitats. On a per-area basis, we also found much higher densities of salmon along the shoreline than in channel habitats. For Chinook Salmon, habitat use also differed by genetic stock of origin: upper-river stocks primarily used deeper channels, while lower-river populations used both channel and shoreline areas. We concluded that sampling at both habitat types is required to fully encompass the migration patterns of all salmon evolutionarily significant units in the Columbia River basin. These spatial and temporal variations in salmon timing and density have ramifications for feeding, growth, and competitive interactions. This study provides information that is relevant for conservation efforts targeting specific fish populations and efforts to evaluate the potential impacts of in-water activities in the Columbia River estuary.

For large complex enterprises this is critical to limiting the authorized access of insiders. However, the specifications describe the required access control capabilities but not the related algorithms. While appropriate, this leave open the important question as to whether or not NGAC is scalable. Existing cubic reference implementations indicate that it does not. For example, the primary NGAC reference implementation took several minutes to simply display the set of files accessible to a user on a moderately sized system. To solve this problem we provide an efficient access control decision algorithm, reducing the overall complexity from cubic to linear. Our other major contribution is to provide a novel mechanism for administrators and users to review allowed access rights. We provide an interface that appears to be a simple file directory hierarchy but in reality is an automatically generated structure abstracted from the underlying access control graph that works with any set of simultaneously instantiated access control policies. Our work thus provides the first efficient implementation of NGAC while enabling user privilege review through a novel visualization approach. These capabilities help limit insider access to information (and thereby limit information leakage) by enabling the efficient simultaneous instantiation of multiple access control policies.

In our approach a frequency-stabilized laser frequency comb is employed as a reference for a scanning CW laser measurement of the temperature sensitivity of a fiber Fabry-Perot interferometer (FFP). For an in-house constructed, actively stabilized FFP, we observe the thermal sensitivity of a resonance mode at 1319 nm of -7.4 GHz C-1, which corresponds to a fractional thermal sensitivity of -3.2 x 10(-5) C-1. We compare these results to a simple model and discuss further the materials construction and stabilization of the FFP. Our measurement technique is one step toward a broad characterization of Fabry-Perot instruments, and this FFP in particular is currently being investigated as a wavelength calibration source in precision radial velocity spectroscopy to discover terrestrial-mass exoplanets.

We make the case that a breakthrough in angular resolution imaging capabilities is required in order to unravel the processes involved in planet formation. PFI will be optimised to provide a complete census of the protoplanet population at all stellocentric radii and over the age range from 0.1 to similar to 100 Myr. Within this age period, planetary systems undergo dramatic changes and the final architecture of planetary systems is determined. Our goal is to study the planetary birth on the natural spatial scale where the material is assembled, which is the "Hill Sphere" of the forming planet, and to characterise the protoplanetary cores by measuring their masses and physical properties. Our science working group has investigated the observational characteristics of these young protoplanets as well as the migration mechanisms that might alter the system architecture. We simulated the imprints that the planets leave in the disk and study how PFI could revolutionise areas ranging from exoplanet to extragalactic science. In this contribution we outline the key science drivers of PFI and discuss the requirements that will guide the technology choices, the site selection, and potential science/technology tradeoffs.

It has been applied to the interaction of short, intense laser radiation (attosecond pulses) to describe the single and double ionization of atoms and molecules, but the approach is not limited to this particular application. The paper begins with a brief description of the method and algorithms and then discusses how they have been successfully ported to the Intel Phi coprocessors(1). While further experimentation is needed, the results provide reasonable evidence that by suitably modifying the code to combine MPI, OpenMP, and compiler assisted offload (CAO) directives, one can achieve a significant improvement in performance from these coprocessors for problems such as the above. Future work will examine porting the code to GPU's and a comparison in performance of the two coprocessors.

At low temperature, such a gas shows both magnetic and superfluid order, and undergoes both density and spin dynamics. These lecture notes present a general overview of the properties of spinor Bose-Einstein gases. The notes are divided in five sections. In the first, we summarize basic properties of multi-component quantum fluids, focusing on the specific case of spinor Bose-Einstein gases and the role of rotational symmetry in defining their properties. Second, we consider the magnetic state of a spinor Bose-Einstein gas, highlighting effects of thermodynamics and Bose-Einstein statistics and also of spin-dependent interactions between atoms. In the third section, we discuss methods for measuring the properties of magnetically ordered quantum gases and present newly developed schemes for spin-dependent imaging. We then discuss the dynamics of spin mixing in which the spin composition of the gas evolves through the spin-dependent interactions within the gas. We discuss spin mixing first from a microscopic perspective, and then advance to discussing collective and beyond-mean-field dynamics. The fifth section reviews recent studies of the magnetic excitations of quantum-degenerate spinor Bose gases. We conclude with some perspectives on future directions for research. C1 [Marti, G.

From a boiling pot of water to the complex dynamics of quantum many-body systems it provides a successful connection between the microscopic dynamics of atoms and molecules and the macroscopic properties of matter. However, statistical mechanics only describes the thermal equilibrium situation of a system, and there is no general framework to describe how equilibrium is reached or under which circumstances it can be reached at all. This problem is particularly challenging in quantum mechanics, where unitarity appears to render the very concept of thermalization counterintuitive. With the rapid experimental progress in the control and probing of ultracold quantum gases this question has become within reach of detailed experimental investigations. In these notes we present a series of experiments with ultracold one-dimensional Bose gases, which provide novel insights into this fundamental question.

First, we created physical models of commercially-available standards that support multiline thru-reflect-line (TRL) and open-short-load-thru (OSLT) calibrations, and included error mechanisms in each of the standards' constituent parameters that were utilized in the NIST Microwave Uncertainty Framework to propagate uncertainties. Next, we created a measurement-based model of a commercial electronic calibration unit (ECU) by characterizing the scattering parameters of its internal states with a multiline TRL calibration. Finally, we calibrated a network analyzer using the three calibration methods, and compared measurements, including uncertainties, made on a number of verification devices. We show that the three calibrations agreed to within their respective uncertainties.

In this work, we present an innovative and effective method for measuring the chute-based fish length based on the morphological midline of the fish. The midline is generated through recursive morphological operations on the segmented fish mask. To conduct reliable measurement, even under harsh environment, we also propose a systematic method for detecting water drop on camera lens. The robust detection, which can be performed either in real-time or in offline processing, is based on a blur measure derived from the gradient of the image and the contour of fish.

In the region of high interest, we will give a smaller quantization parameter to achieve a better image quality; on the contrary, in the region of low interest, we then give a larger quantization parameter to reduce the amount of data.

The response variable was the number of sailfish caught per number of boats registered in the tournament per day. The following factors were tested in the analyses: "year", "month", and "local", representing the main effects of the explanatory variables. The overall pattern of the standardized catch rate indicates a relatively stable trend with a slight decline in the recent years, from 2009 to 2014.

Currently, either complicated and expensive spectral radiometric measurements or broadband photometric LED measurements are used. The broadband photometric measurements are based on the CIE standardized V(lambda) function, which cannot be used in the UV range and leads to large errors when blue or red LEDs are measured in its wings, where the realization is always poor. Reference irradiance meters with spectrally constant response and high-intensity LED irradiance sources were developed here to implement the previously suggested broadband radiometric LED measurement procedure [1, 2]. Using a detector with spectrally constant response, the broadband radiometric quantities of any LEDs or LED groups can be simply measured with low uncertainty without using any source standard. The spectral flatness of filtered-Si detectors and low-noise pyroelectric radiometers are compared. Examples are given for integrated irradiance measurement of UV and blue LED sources using the here introduced reference (standard) pyroelectric irradiance meters. For validation, the broadband measured integrated irradiance of several LED-365 sources were compared with the spectrally determined integrated irradiance derived from an FEL spectral irradiance lamp-standard. Integrated responsivity transfer from the reference irradiance meter to transfer standard and field UV irradiance meters is discussed. C1 [Eppeldauer, G. P.; Cooksey, C. C.; Yoon, H. W.; Hanssen, L.

Linear mixtures of materials in a scene are often the result of areal mixing, where the pixel size of a sensor is relatively large so they contain patches of different materials within them. Non-linear mixtures are likely to occur with microscopic mixtures of solids, such as mixtures of powders, or mixtures of liquids, or wherever complex scattering of light occurs. This study considers two approaches for use as generalized methods for un-mixing pixels in a scene that may be linear or non-linear. One method is based on earlier studies that indicate non-linear mixtures in reflectance space are approximately linear in albedo space. This method converts reflectance to single-scattering albedo (SSA) according to Hapke theory assuming bidirectional scattering at nadir look angles and uses a constrained linear model on the computed albedo values. The other method is motivated by the same idea, but uses a kernel that seeks to capture the linear behavior of albedo in non-linear mixtures of materials. The behavior of the kernel method can be highly dependent on the value of a parameter, gamma, which provides flexibility for the kernel method to respond to both linear and non-linear phenomena. Our study pays particular attention to this parameter for responding to linear and non-linear mixtures. Laboratory experiments on both granular solids and liquid solutions are performed with scenes of hyperspectral data.

Owing to the wide area coverage, high spatial resolution and short repeat cycle of observations satellites present one of the key components of the global snow and ice cover monitoring system. The Global Multisensor Automated Snow and Ice Mapping System (GMASI) has been developed at the request of NOAA National Weather Service (NWS) and NOAA National Ice Center (NIC) to facilitate NOAA operational monitoring of snow and ice cover and to provide information on snow and ice for use in NWP models. Since 2006 the system has been routinely generating daily snow and ice cover maps using combined observations in the visible/infrared and in the microwave from operational meteorological satellites. The output product provides continuous (gap free) characterization of the global snow and ice cover distribution at 4 km spatial resolution. The paper presents a basic description of the snow and ice mapping algorithms incorporated in the system as well as of the product generated with GMASI. It explains the approach used to validate the derived snow and ice maps and provides the results of their accuracy assessment.

One interpretation describes a young-fish scenario with a life span near 10-12 years, whereas another interpretation describes an old-fish scenario at more than 30 years. In this study, lead-radium dating was performed on Pacific cod otoliths to test the validity of the old-fish age reading scenario. Radiometric ages revealed that the young-fish scenario was valid because the actual age of the two oldest adult groups was more than 20 years younger than estimated by the old-fish scenario.

The Suomi National Polar-orbiting Partnership (Soumi NPP) satellite Environmental Data Records (EDRs) are retrieved from calibrated ultraspectral radiance or Sensor Data Records (SDRs). Understanding the accuracy of retrieved EDRs is critical. The second Suomi NPP Calibration/Validation field campaign was conducted during March 2015 with flights over Greenland. The NASA high-altitude ER-2 aircraft carrying ultraspectral interferometer sounders such as the National Airborne Sounder Testbed-Interferometer (NAST-I) flew under the Suomi NPP satellite that carries the Cross-track Infrared Sounder (CrIS) and the Advanced Technology Microwave Sounder (ATMS). Herein we inter-compare the EDRs produced from different retrieval algorithms employed on these satellite and aircraft campaign data. The available radiosonde measurements together with the European Centre for Medium-Range Weather Forecasts (ECMWF) analyses are used to assess atmospheric temperature and moisture retrievals from the aircraft and satellite platforms. Preliminary results of this experiment under a winter, Arctic environment are presented.

Unfortunately, noise can limit the specimen-specific detail and the information that can be acquired in any SEM micrograph, or measurement made from those data. The majority of SEM measurements are done at low primary electron beam currents and fast imaging mode resulting in rather noisy signals - often too noisy. The amount and the type of the noise and the steps taken to deal with it are critical to the quality and amount of the information gathered. This fifth presentation, in this series of SEM dimensional metrology tutorial papers, discusses some of the various causes of measurement uncertainty in scanned particle beam instruments specifically dealing with signal-to-noise (SNR) and its contribution to measurement imprecision.

Enhancing the utility of these space-borne measurements for biological productivity, biogeochemical cycling and fisheries investigations will require novel bio-optical methods capable of providing information on the community structure, biomass and photo-physiology of phytoplankton associated on spatial scales that match these features. This study showcases high-resolution in-situ measurements of sea water hydrography (SeaBird CTD (R)), CDOM (WetLabs ALF (R)), phytoplankton functional types (PFTs, FlowCAM (R)), biomass (bbe Moldaenke AlgaeOnlineAnalyzer (R) and WetLabs ALF (R)) and phytoplankton photosynthetic competency (mini-FIRe) across microscale features encountered during a recent (Nov. 2014) cruise in support of NOAA's VIIRS ocean color satellite calibration and validation activities. When mapped against binned daily, Level 2 satellite images of Chl a, K(d)490 and SST over the cruise period, these high-resolution in-situ data showed great correspondence with the satellite data, but more importantly allowed for identification of PFTs and water types associated with microscale features. Large assemblages of phytoplankton communities comprising of diatoms and diatom-diazotroph associations (DDAs), were found in mesohaline frontal zones. Despite their high biomass, these populations were characterized by low photosynthetic competency, indicative of a bloom at the end of its active growth possibly due to nitrogen depletion in the water. Other prominent PFTs such as Trichodesmium spp., Synechococcus spp. and cryptophytes, were also associated with specific water masses offering the promise and potential that ocean remote sensing reflectance bands when examined in the context of water types also measurable from space, could greatly enhance the utility of satellite measurements for biological oceanographic, carbon cycling and fisheries studies.

With this improvement in phase coherence, we have observed a reduction in the light shift by over two orders of magnitude. We present the impact of this improvement on the performance of the clock, for which the light shift was previously dominated by the incoherent light in the laser spectrum. We also demonstrate a new optical setup to reduce the Doppler shift. C1 [Liu, Xiaochi; Kitching, John; Donley, Elizabeth A.] NIST, Div Time & Frequency, Boulder, CO 80305 USA.

This adaptation and change in focus necessitates at the very least modification, and potentially, wholesale new developments to ensure that resilient-and agile-aware security testing is available to the research community.

Next generation weather observations are provided by VIIRS instruments, but VIIRS lacks a water vapor channel at 6.7 mu m, allowing for only cloud-tracking of winds. An addition of the 6.7 mu m channel to future VIIRS instruments has been proposed. The additional channel could replace a 750-m channel at 1.6 mu m (M10) that shares spectral response characteristics with a 375-m channel (I3). M10 data would then be synthesized by the 2-by-2 aggregation of I3 pixels. Radiometric response of such a synthesized channel is very similar to the actual one, although some differences exist. In this study, SNR (signal-to-noise ratio) for the M10 data simulated by the aggregation of the I3 pixels was compared with SNR for the actual M10 data. SNR for the simulated M10 was found to be always lower than SNR for the actual M10. This result contrasts with results of an analogous SNR comparison for bands I2 and M7 that share the same spectral response at 865 nm. Aggregated I2 data have SNR comparable to actual M7 data measured with the low gain, although lower than high-gain M7. The main reason for the different SNR behavior may be the use of microlenses with the I3 and M10 detectors, but not with the I2 and M7 ones.

Despite a large number of currently available automated satellite-based sea ice extent datasets, analysts at the National Ice Center tend to rely on original satellite imagery (provided by satellite optical, passive microwave and active microwave sensors) mainly because the automated products derived from satellite optical data have gaps in the area coverage due to clouds and darkness, passive microwave products have poor spatial resolution, automated ice identifications based on radar data are not quite reliable due to a considerable difficulty in discriminating between the ice cover and rough ice-free ocean surface due to winds. We have developed a multi-sensor algorithm that first extracts maximum information on the sea ice cover from imaging instruments VIIRS and MODIS, including regions covered by thin, semitransparent clouds, then supplements the output by the microwave measurements and finally aggregates the results into a cloud gap free daily product. This ability to identify ice cover underneath thin clouds, which is usually masked out by traditional cloud detection algorithms, allows for expansion of the effective coverage of the sea ice maps and thus more accurate and detailed delineation of the ice edge. We have also developed a web-based monitoring system that allows comparison of our daily ice extent product with the several other independent operational daily products.

In normal operation, the BB temperature is set to 292.5 K providing one radiance level. From the NOAA's Integrated Calibration and Validation System (ICVS) monitoring system, the TEB calibration factors (F-factors) have been trended and show very stable responses, however the BB Warm-Up-Cool-Down (WUCD) cycles provide detectors' gain and temperature dependent sensitivity measurements. Since the launch of S-NPP, the NOAA Sea Surface Temperature (SST) group noticed unexpected global SST anomalies during the WUCD cycles. In this study, the TEB F-factors are calculated during the WUCD cycle on June 17th 2015. The TEB F-factors are analyzed by identifying the VIIRS On-Board Calibrator Intermediate Product (OBCIP) files to be Warm-Up or Cool-Down granules. To correct the SST anomaly, an F-factor correction parameter is calculated by the modified C1 (or b1) values which are derived from the linear portion of C1 coefficient during the WUCD. The F-factor correction factors are applied back to the original VIIRS SST bands showing significantly reducing the F-factor changes. Obvious improvements are observed in M12, M14 and M16, but corrections effects are hardly seen in M16. Further investigation is needed to find out the source of the F-factor oscillations during the WUCD. C1 [Choi, Taeyoung] Earth Resource Technol Inc, Jodhpur, Rajasthan, India.

Four ABI flight modules (FM) are planned to be launched on GOES-R,S,T,U, the first one in the fall of 2016. Pre-launch testing is on-going for FM3 and FM4. ABI has 16 spectral channels, six in the visible/near infrared (VNIR 0.47 - 2.25 mu m), and ten in the thermal infrared (TIR 3.9 - 13.3 mu m) spectral regions, to be calibrated on-orbit by observing respectively a solar diffuser and a blackbody. Each channel has hundreds of detectors arranged in columns. Operationally one Analytic Generation of Spectral Response (ANGEN) function will be used to represent the spectral response function (SRF) of all detectors in a band. The Vendor conducted prelaunch end-to-end SRF testing to compare to ANGEN; detector specific SRF data was taken for: i) best detector selected (BDS) mode - for FM 2,3, and 4; and ii) all detectors (column mode) - for four spectral bands in FM3 and FM4. The GOES-R calibration working group (CWG) has independently used the SRF test data for FM2 and FM3 to study the potential impact of detector-to-detector SRF differences on the ABI detected Earth view radiances. In this paper we expand the CWG analysis to include the FM4 SRF test data - the results are in agreement with the Vendor analysis, and show excellent instrument performance and compare the detector-to-detector SRF differences and their potential impact on the detected Earth view radiances for all of the tested ABI modules.

The majority of recent and current space instruments use reflective diffusers. As a result, numerous Bidirectional Reflectance Distribution Function (BRDF) calibration comparisons have been conducted between the National Institute of Standards and Technology (NIST) and other industry and university-based metrology laboratories. However, based on literature searches and communications with NIST and other laboratories, no Bidirectional Transmittance Distribution Function (BTDF) measurement comparisons have been conducted between National Measurement Laboratories (NMLs) and other metrology laboratories. On the other hand, there is a growing interest in the use of transmissive diffusers in the calibration of satellite, air-borne, and ground-based remote sensing instruments. Current remote sensing instruments employing transmissive diffusers include the Ozone Mapping and Profiler Suite instrument (OMPS) Limb instrument on the Suomi-National Polar-orbiting Partnership (S-NPP) platform,, the Geostationary Ocean Color Imager (GOCI) on the Korea Aerospace Research Institute's (KARI) Communication, Ocean, and Meteorological Satellite (COMS), the Ozone Monitoring Instrument (OMI) on NASA's Earth Observing System (EOS) Aura platform, the Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument and the Geostationary Environmental Monitoring Spectrometer (GEMS).. This ensemble of instruments requires validated BTDF measurements of their onboard transmissive diffusers from the ultraviolet through the near infrared. This paper presents the preliminary results of a BTDF comparison between the NASA Diffuser Calibration Laboratory (DCL) and NIST on quartz and thin Spectralon samples.

Great emphasis has been placed in the development of methodologies to achieve the ABI GOES-R field campaign primary objective - validation of ABI L1b spectral radiance observations to ensure the SI traceability established pre-launch. An integrated approach using high-altitude aircraft, near surface UAS, and satellite reference measurements was developed to achieve the ABI validation objectives of the GOES-R field campaign. The high-altitude aircraft measurements coupled with special ABI collections are planned to provide the primary pathway (direct comparison) to validate ABI SI traceability of all ABI operational detectors. Near surface Unmanned Aircraft Systems (UAS) are planned to provide a secondary pathway to validate ABI SI traceability through coincident near surface measurements of Earth validation targets using the Earth's surface as a reference (indirect comparison). Satellite reference measurements obtained through special ABI collections and Simultaneous Nadir Overpass (SNO) of reference sensors will also provide a secondary pathway to validate ABI SI traceability. A detailed description of each validation approach, the critical components, and the preliminary expected uncertainties will be presented. The combined collections offer advanced post-launch validation capabilities and foster new perspectives for science teams during the post-launch validation and monitoring of NOAA's next generation of operational environmental satellites.

The campaign plans include a feasibility demonstration study for new near surface unmanned aircraft system (UAS) measurement capability that is being developed to meet the challenges of validating geostationary sensors. We report our progress in developing our initial systems by presenting the design and preliminary characterization results of the sensor suite. The design takes advantage of off-the-shelf technologies and fiber-based optical components to make hemispheric directional measurements from a UAS. The characterization results -- including laboratory measurements of temperature effects and polarization sensitivity -- are used to refine the radiometric uncertainty budget towards meeting the validation objectives for the campaign. These systems will foster improved validation capabilities for the GOES-R field campaign and other next generation satellite systems.

This source is unique in that it can be used in situ, in both ambient and thermal-vacuum environments, allowing it to follow the sensor throughout its testing cycle. The performance of the original flat plate radiometric source was presented at the 2009 SPIE1. Following the original efforts, design upgrades were incorporated into the source to improve both radiometric throughput and uniformity. The pre-thermal-vacuum (pre-TVAC) testing results of a spacecraft-level optical sensor with the improved flat plate illumination source, both in ambient and vacuum environments, are presented.

The 3.9-mu m channel imagery of AHI has spatial resolution of 2 km and performs routine full-disk imaging every 10 minutes. There have been stray light observed in the full disk imagery of the AHI 3.9-mu m channel over a few weeks around February and October-November when the line of sight of the sun is at similar to 10 to similar to 20 degrees south of the nadir of the Himawari-8. In this paper, difference data between consecutive AHI 3.9-mu m images have been processed to quantitatively characterize and monitor the AHI stray light. Stray light indices are also developed to trend the occurrence, position and magnitude of the stray light in the AHI 3.9-mu m imageries. It is also found that the stray light is the greatest in the AHI 3.9-mu m band but also is detectable in other Mid-Wavelength IR channels. Analysis of the ratio of stray light magnitude between AHI 3.9-mu m and 6.2-mu m band indicates that it is consistent with the ratio of solar radiance for these two bands. This suggests that the stray light is mainly due to direct illumination of the attenuated solar radiation on the AHI detector rather than from onboard thermal body emission due to heating. The upcoming Advanced Baseline Imager (ABI) onboard the GOES-R satellite has very similar spectral and spatial characteristics as AHI. Therefore, characterizing the stray light in the 3.9-mu m channel of AHI helps support post-launch calibration activities of ABI.

They are the Terra (T) and Aqua (A) platforms which tracks the Earth in the morning and afternoon orbits. T-MODIS has continued to operate over 15 years easily surpassing the 6 year design life time on orbit. Of the several science products derived from MODIS, one of the primary derivatives is the MODIS Cloud Mask (MOD035). The cloud mask algorithm incorporates several of the MODIS channels in both reflective and thermal infrared wavelengths to identify cloud pixels from clear sky. Two of the thermal infrared channels used in detecting clouds are the 6.7 mu m and 8.5 mu m. Based on a difference threshold with the 11 mu m channel, the 6.7 mu m channel helps in identifying thick high clouds while the 8.5 mu m channel being useful for identifying thin clouds. Starting 2010, it had been observed in the cloud mask products that several pixels have been misclassified due to the change in the thermal band radiometry. The long-term radiometric changes in these thermal channels have been attributed to the electronic crosstalk contamination. In this paper, the improvement in cloud detection using the 6.7 mu m and 8.5 mu m channels are demonstrated using the electronic crosstalk correction. The electronic crosstalk phenomena analysis and characterization were developed using the regular moon observation of MODIS and reported in several works. The results presented in this paper should significantly help in improving the MOD035 product, maintaining the long term dataset from T-MODIS which is important for global change monitoring.

The cause for the issue has been identified to be crosstalk, which is significantly amplified since 2010 due to severe degradation in the electronic circuitry. The crosstalk effect causes unexpected discontinuity/change in the calibration coefficients and induces strong striping artifacts in the earth view (EV) images. Also it is noticed, that there are large long-term drifts in the EV brightness temperature (BT) in these bands. An algorithm using a linear approximation derived from on-orbit lunar observations has been developed to correct the crosstalk effect for them. It was demonstrated that the crosstalk correction can remarkably minimize the discontinuity/change in the calibration coefficients, substantially reduce the striping in the EV images, and significantly remove the long-term drift in the EV BT in all these bands. In this paper, we present the recent progresses in the crosstalk effect analysis and its mitigation. In addition, we will show that besides these four bands, the TEBs in other satellite remote sensors also have significant crosstalk contaminations. Further, it will be demonstrated that the crosstalk correction algorithm we developed can be successfully applied to all the contaminated TEBs to significantly reduce the crosstalk effects and substantially improve both the image quality and the radiometric accuracy of Level-1B (L1B) products for the bands.

VIIRS has 22 spectral bands, among which fourteen are reflective solar bands (RSB) covering a spectral range from 0.410 to 2.25 mu m. The SNPP VIIRS RSB have performed very well since launch. The radiometric calibration for the RSB has also reached a mature stage after almost five years since its launch. Numerous improvements have been made in the standard RSB calibration methodology. Additionally, a hybrid calibration method, which takes the advantages of both solar diffuser calibration and lunar calibration and avoids the drawbacks of the two methods, successfully finalizes the highly accurate calibration for VIIRS RSB. The successfully calibrated RSB data record significantly impacts the ocean color products, whose stringent requirements are especially sensitive to calibration accuracy, and helps the ocean color products to reach maturity and high quality. Nevertheless, there are still many challenge issues to be investigated for further improvements of the VIIRS sensor data records (SDR). In this presentation, the robust results of the RSB calibrations and the ocean product performance will be presented.

This permits the measurement of the SD reflectance performance, measured by the SD stability monitor (SDSM) at a given outgoing angle with respect to the SD, to be used as a valid substitute for the SD reflectance performance toward the RSB direction that is at a different outgoing angle. Recent in-depth studies have uncovered evidence to contradict this assumption, and due to this difference in the outgoing angles between the RSBs and SDSM, the RSB calibration coefficients inherit growing bias. In this exposition, we will explicitly show the evolving angular dependence in SD degradation for SNPP VIIRS and Terra/Aqua MODIS. By examining the angular dependence of the available detector response within each calibration event we are able to build a historical trend clearly demonstrating evolving angular dependence. We refer to this phenomenon as the "SD degradation nonuniformity effect". Our finding lays out a very basic mismatch between the use of the SD and the current official RSB calibration methodology that will be an important issue to be addressed.

The on-board calibration of the VIIRS reflective solar bands (RSB) relies on a solar diffuser (SD) located at a fixed scan angle and a solar diffuser stability monitor (SDSM). The VIIRS response versus scan angle (RVS) was characterized prelaunch in ambient conditions and is currently used to determine the on-orbit response for all scan angles relative to the SD scan angle. Since the RVS is vitally important to the quality of calibrated level 1B products, it is important to monitor its on-orbit stability. In this study, the RVS stability is examined based on reflectance trends collected from 16-day repeatable orbits over pre-selected pseudo-invariant desert sites in Northern Africa. These trends nearly cover the entire Earth view scan range so that any systematic drifts in the scan angle direction would indicate a change in RVS. This study also compares VIIRS RVS on-orbit stability results with those from both Aqua and Terra MODIS over the first four years of mission for a few selected bands, which provides further information on potential VIIRS RVS on-orbit changes.

We compare the match and non-match distributions for short-time-lapse image pairs, acquired with no more than 120 days of time lapse between them, to the distributions for long-time-lapse image pairs, with at least 1,200 days of time lapse. We find no substantial difference in the non-match, or impostor, distribution between the short-time-lapse and the long-time-lapse data. We do find a difference in the match, or authentic, distributions. For the image dataset and iris biometric systems used in this work, the false reject rate increases by about 50% or greater for the long-time-lapse data relative to the short-time-lapse data. The magnitude of the increase in the false reject rate varies with changes in the decision threshold, and with different matching algorithms. Our results demonstrate that iris biometrics is subject to a template aging effect. C1 [Baker, Sarah E.; Bowyer, Kevin W.; Flynn, Patrick J.] Univ Notre Dame, Notre Dame, IN 46556 USA. [Phillips, P.

During isothermal constant-current operation at subfreezing temperatures, water forming at the cathode initially hydrates the membrane, then forms ice in the catalyst layer and/or GDL. This ice formation results in a gradual decay in voltage. High-frequency resistance initially decreases due to an increase in membrane water content and then increases over time as the contact resistance increases. The water/ice holding capacity of a fuel cell decreases with decreasing subfreezing temperature (-10 degrees C vs. -20 degrees C vs. -30 degrees C) and increasing current density (0.02 A cm(-2) vs. 0.04 A cm(-2)). Ice formation monitored using in-situ high-resolution neutron radiography indicated that the ice was concentrated near the cathode catalyst layer at low operating temperatures (approximate to-20 degrees C) and high current densities (0.04 A cm(-2)). Significant ice formation was also observed in the GDLs at higher subfreezing temperatures (approximate to-10 degrees C) and lower current densities (0.02 A cm(-2)). These results are in good agreement with the long-term durability observations that show more severe degradation at lower temperatures (-20 degrees C and -30 degrees C). (C) The Author(s) 2016.

Understanding and modeling diffuse scatter from various textured silicon surfaces should aid in increasing light trapping in these materials, as well as improving material characterization and inspection during manufacture. We have performed Mueller matrix bidirectional reflectance distribution function (BRDF) measurements from a variety of textured silicon surfaces. Simulations, using multiple reflection polarization ray tracing, reproduce many of the features in the data. Evidence for diffraction, however, can also be observed, suggesting that a purely ray-tracing approach is insufficient for accurately describing the scatter from these materials.

A model sample of commercial PPE backsheet, namely polyethylene terephthalate/polyethylene terephthalate/ethylene vinyl acetate (PET/PET/EVA) was investigated. Outdoor aging was performed in Gaithersburg, Maryland, USA for up to 510 days, and complementary accelerated laboratory aging was conducted on the NIST (National Institute of Standards and Technology) SPHERE (Simulated Photodegradation via High Energy Radiant Exposure). Fracture energy, mode I stress intensity factor and film strength were analyzed using an analytical model based on channel cracking fragmentation testing results. The correlation between mechanical and chemical degradation was discussed for both outdoor and accelerated laboratory aging.

It is widely cultivated in all of the districts and ranks second after rice in production. Bangladesh is the fourth largest potato producer in Asia and is among the world's top 15 potato producing countries. The weather condition for potato cultivation is favorable during the sowing, growing and harvesting period. It is a winter crop and is cultivated during the period of November to March. Bangladesh is mainly an agricultural based country with respect to agriculture's contribution to GDP, employment and consumption. Potato is a prominent crop in consideration of production, its internal demand and economic value. Bangladesh has a big economic activities related to potato cultivation and marketing, especially the economic relations among farmers, traders, stockers and cold storage owners. Potato yield prediction before harvest is an important issue for the Government and the stakeholders in managing and controlling the potato market. Advanced very high resolution radiometer (AVHRR) based satellite data product vegetation health indices VCI (vegetation condition index) and TCI (temperature condition index) are used as predictors for early prediction.

We report that, not only does increasing the surface charge density lead to greater structural ordering and a stiffening of the membrane, which is consistent with classical theory of charge effects on membranes, but also that the relaxation rate of the membrane thickness fluctuations decreases without affecting the fluctuation amplitude. From the relaxation rate we demonstrate, using recent theory, that the viscosity of the surfactant membrane is increased with surface charge density, which suggests that the amount of charge controls the diffusion behavior of inclusions inside the membrane. The present results confirm that the thickness fluctuation relaxation rate and amplitude are tuned independently since the membrane viscosity is only influencing the relaxation rate. This work demonstrates that charge stabilization of lamellar bilayers is not merely affected by intermembrane interactions and structural ordering but that intramembrane dynamics also have a significant contribution.

Their disruption can cause cascading effects, influencing the economy of an entire region. Past hazard events show that water availability is crucial for minimizing the societal impact of such events and for recovery processes. To date, stochastic simulations of hazards events, and their direct and indirect physical damage to water system components, are typically not coupled with hydraulic simulations of functionality loss and restoration, including water quality, pressure, and flow throughout the network. This work presents a comprehensive approach to the modeling of water system resilience subject to a seismic event; however, the procedure is general and can be applied to other network systems and hazards. The model performs: (1) a baseline deterministic hydraulic analysis on an undamaged water system, focusing on meaningful functionality metrics, (i.e., water pressure, quantity, and quality); (2) a probabilistic analysis of the damaged system considering the damage state and the performance level of each component; (3) a probabilistic analysis of the water system functionality, considering the physical damage analysis and the recovery time of each component.

The control mechanism typically used for traffic lights operates based on a periodic schedule to change the light (red/yellow/green). In many cases, a different schedule is used in late night/early morning hours. This fixed control mechanism does not adequately account for changing traffic conditions, and is unaware of/unresponsive to congestion. In this work, we propose a framework for dynamic traffic light control at intersections. The framework relies on a simple sensor network to collect traffic data and includes novel protocols for traffic flow control to handle congestion and facilitate flow. We show that our proposed algorithms have low overhead and are practical to employ in live traffic flow scenarios. Through extensive simulations, we demonstrate the benefits of our framework in optimizing traffic flow metrics, such as traffic throughput, average vehicle waiting time, and vehicle waiting line length.

In this paper, we investigate two transmit diversity applications of LDC for orthogonal frequency division multiplexing (OFDM) systems in order to achieve space-time/ frequency (ST/SF) diversity gains when transmitting over time-/frequency-selective fading channels. LDC-aided ST/SF-OFDM is flexible in configuring various numbers of transmit antennas and time-slots or frequency-tones. Our results show that the ST-OFDM scheme is sensitive to exploiting diversity gains, subject to the impact of varying channel Doppler spreads; while the performance of SF-OFDM is mainly subject to delay spread. Particularly, when the transmitter employs more than two antennas, the LDC-aided ST/SF-OFDM outperforms the orthogonal block codes (e.g. Tarokh's codes) aided ST/SF-OFDM, when communicating over higher Doppler/delay spread.

It not only involves multiple, interacting, heterogeneous cyber-physical domains, but also requires tight integration of power markets, dynamic pricing and transactions, and price-sensitive consumer behavior, where consumers can also be producers of power. These dynamics introduce a huge challenge of maintaining stability of the power grid. Moreover, evolving business models and regulatory environment, including human factors need to be a key part of the evaluation as they directly affect the demand-response in the grid. Furthermore, as sensors and computations are becoming more distributed on edge devices and as they often employ normal communication channels, cyber security of the critical power grid infrastructure has become ever more important to prevent cyber intrusions and attacks. Current research has largely focused on one or a few of these challenges and the simulation tools developed cater to these individual tasks, such as network simulators, power distribution simulators, or human organization and policy simulators. However, to attain a deeper understanding of the transactive grid behavior, analysis of grid stability, and to optimize resources both from consumers' and generators' perspective, a comprehensive platform is needed to facilitate end-to-end evaluation of all of these aspects. This paper describes an open platform that provides a coherent framework for integrated transactive energy simulations of smart grids and is readily customizable and extensible for various simulation tools.

The project goal was to build an autonomously operating, passive-acoustic observatory which allows scientists (1) to reliably and continuously record the Antarctic underwater soundscape yearround, (2) to record all vocalizations produced by marine mammals in the study area (frequency range of the recordings: 10 Hz to 96 kHz), (3) to locate vocalizing marine mammals and other underwater sound sources, (4) to obtain information on ambient noise levels in the area, and (5) to access and analyze the incoming acoustic data stream in real time at the Alfred Wegener Institute for Polar and Marine Research (AWI) located in Bremerhaven, Germany.

Trajectories are determined by a three-dimensional Monte Carlo calculation that includes drag forces, Brownian motion, and optical gradient forces. We analyze the case of polystyrene particles with radii of order 100 nm carried across a Gaussian-mode standing wave by slowly flowing air. Particles are injected into the flowing air from a small source area such as the end of a capillary tube. Different sizes are dispersed continuously in space on the opposite side of the standing wave, demonstrating a practical way to sort particles. Certain discrete values of particle size show no interaction with the optical field, independent of intensity. These particles can be sorted with exceptionally high resolution. For example, particles with radii of 275 nm can be sorted with 1 nm resolution. This sorting scheme has the advantages of accommodating a high throughput, producing a continuous stream of continuously dispersed particles, and exhibiting excellent size resolution. The Monte Carlo results are in agreement with those obtained by a much simpler, and faster, fluid calculation based on effective velocities and effective diffusion coefficients, both obtained by averaging trajectories over multiple fringes of the optical field.

Here, we present monolithic silicon nitride (Si3N4) cavity optomechanical transducer, in which high f(m) and Q(m) are achieved simultaneously. A nanoscale tuning fork mechanical resonator is near-field coupled with a microdisk optical resonator, allowing the displacement of mechanical resonator to be optically read out. Compared with a single beam with same length, width, and thickness, the tuning fork simultaneously increases f(m) and Q(m) by up to 1.4 and 12 times, respectively. A design enabled, on-chip stress tuning method is also demonstrated. By engineering the clamp design, we increased the stress in the tuning fork by 3 times that of the Si3N4 film. A fundamental mechanical in-plane squeezing mode with f(m) approximate to 29 MHz and Q(m) approximate to 2.2x10(5) is experimentally achieved in a high-stress tuning fork device, corresponding to a f(m)Q(m) product of 6.35x10(12) Hz. The tuning fork cavity optomechanical sensors may find applications where both temporal resolution and sensitivity are important such as atomic force microscopy.

TI Toward a modular multi-material nanoparticle synthesis and assembly strategy via bionanocombinatorics: bifunctional peptides for linking Au and Ag nanomaterials SO PHYSICAL CHEMISTRY CHEMICAL PHYSICS LA English DT Article ID UNNATURAL AMINO-ACIDS; GOLD NANOPARTICLES; ASYMMETRIC FUNCTIONALIZATION; BINDING PEPTIDE; ADSORPTION; PROTEINS; SEQUENCE; CRYSTALLIZATION; SUPERSTRUCTURES; NANOSTRUCTURES AB Materials-binding peptides represent a unique avenue towards controlling the shape and size of nanoparticles (NPs) grown under aqueous conditions. Here, employing a bionanocombinatorics approach, two such materials-binding peptides were linked at either end of a photoswitchable spacer, forming a multi-domain materials-binding molecule to control the in situ synthesis and organization of Ag and Au NPs under ambient conditions. These multi-domain molecules retained the peptides' ability to nucleate, grow, and stabilize Ag and Au NPs in aqueous media. Disordered co-assemblies of the two nanomaterials were observed by TEM imaging of dried samples after sequential growth of the two metals, and showed a clustering behavior that was not typically observed without both metals and the linker molecules. While TEM evidence suggested the formation of AuNP/AgNP assemblies upon drying, SAXS analysis indicated that no extended assemblies existed in solution, suggesting that sample drying plays an important role in facilitating NP clustering. Molecular simulations and experimental data revealed tunable materials-binding based upon the isomerization state of the photoswitchable unit and metal employed. This work is a first step in generating externally actuated biomolecules with specific material-binding properties that could be used as the building blocks to achieve multi-material switchable NP assemblies.

The cross sections at midspan (i.e., expected plastic hinge zone) of the beam specimen were directly exposed to the natural gas fire. Two different tests were conducted: (1) fire-thermal tests to evaluate the effects of the prescribed heat release rates (HRR), provided by the 1 m(2) natural gas burner, on the thermal responses of the specimen and (2) structural-fire test to evaluate the fire effects on the overall behavior and the load-bearing capacity of the specimen. The test results indicated that the prescribed heat release rates from the burner affected the heating rate of the specimen. When the HRR-time relationship of the burner followed a step function, the fire-exposed region of the beam specimen was heated essentially linearly with increasing time of fire exposure. When the HRR was set to a target magnitude of 400 kW throughout the test, the fire-exposed region was heated nonlinearly until it reached a steady-state temperature condition. When the beam specimen was subjected to linearly increasing flexural loads at a maintained HRR of 700 kW, combined flexural and lateral torsional failure of the specimen was exhibited. The lateral deformations in the compression flange at the fire-exposed critical sections initiated at 124 +/- 5 kN-m, which is 39% of the plastic moment capacity at room temperature. The peak moment capacity was 171 +/- 9 kN-m (54 % of the plastic moment capacity at room temperature), while the maximum temperature was 642 +/- 28 degrees C at the HRR of 700 kW. The test results from the present study can be used for developing or calibrating analytical models, which can be eventually used for evaluating the performance of structural members subjected to a localized fire.

The detailed modeling approach represents the concrete slab with solid elements and the steel decking with shell elements. The reduced-order modeling approach represents the thick and thin parts of a composite slab with alternating strips of layered shell elements. The detailed modeling approach was validated against experimental results available in the literature, and the reduced-order modeling approach was calibrated and verified against the detailed model results. A parametric study using the detailed modeling approach was conducted to investigate the influence of slab geometry on the temperature distribution within composite slabs. The results show that the rib height of the decking and the width at the top of the rib are key factors governing the temperature distribution in the rib. The paper also presents comparisons with Eurocode 4 calculations of fire resistance of composite slabs. The comparisons indicate that the Eurocode 4 overestimates the fire resistance compared to the numerical results by up to 12 %.

Three different high-temperature stress-strain models were compared: the model recently developed by the National Institute of Standards and Technology (NIST) [1], the Eurocode 3 model [2] and the model developed by Lie [3]. The testbed used in the analyses included twenty steel column tests and two restrained steel beam tests reported in the technical literature. The selected column tests reported buckling temperatures ranging from 500 C-o to 700 C-o and applied axial load ranging from 20 % to 65 % of the axial-load capacity at ambient temperature. Each reported test was analyzed in two different ways: (1) finite-element model was developed to predict the buckling temperature of the steel columns and response of the restrained steel beams in fire condition. (2) member capacity equations prescribed in Eurocode 3 and ANSI/AISC-360-10 [4] were used to compute the buckling temperature of the steel columns. Overall, the results indicate that all investigated material models give acceptable prediction of the buckling temperature of the steel columns and the behavior of restrained beams. The finite-element model with the NIST and the Lie material models predict the buckling temperature more accurately than that with the EC 3 material model. When the Eurocode column capacity equations were used, the buckling temperatures calculated using the NIST and the EC 3 models are more comparable with test results than those using the Lie model. It was also found that the current ANSI/AISC360-10 Appendix 4 equation conservatively estimate the buckling temperature of the tested column specimens with difference of 20% on average. When the standard column equation in the Chapter E of ANSI/AISC360-10 was used, both the EC 3 and the NIST models accurately predict the buckling temperature of the tested column specimen with difference less than 5% on average.

It has been widely used in fire engineering for modeling the gas phase environment (temperature, heat flux, velocity, species concentrations, etc.) in fires. Recently, there has been increased research in the application of FDS for structural fire analysis. Fire-structure interface tools for transferring data from FDS to particular FEM codes (such as ANSYS, ABAQUS, SAFIR) have been developed. Although both FDS and FEM codes have been separately validated, there needs to be a direct validation for the integrated FDS-FEM simulation methodology. This paper validates the integrated FDS-FEM simulation methodology against a number of localized fire tests reported in literature. Localized fire tests on steel columns and on ceiling steel beams were simulated using the FDS-FEM method. The concept of adiabatic surface temperature used for transferring data from FDS to FEM was presented and the limitation of the concept was discussed. The FEM program ANSYS was used to conduct the heat transfer analyses and thermo-mechanical analyses to get the temperature and structural responses of the tested steel beams and steel columns.

For larger G, the dendrimers become similar to porous particles, but the molecule segregates segregates into subdomains at G = 9, reflecting the branching complexity of the first dendrimer generation.

In particular, we compare the radius of gyration (R-g) of an individual grafted chain to its value in solution and we use path-integration to estimate the change delta R-h of the hydrodynamic radius of ssDNA-grafted NPs (R-h) from the hydrodynamic radius of the bare gold NP core (R = 5.0 nm) for a range of grafted chains (N), chain lengths (L), and persistence lengths (l(p)) relevant to experimental studies of these NPs. We find the ssDNA chain size is not greatly perturbed from its free solution value so that the molecular cartoon of a brush-like layer involving highly extended ssDNA chains is an unrealistic model of the interfacial structure of ssDNA-grafted NPs under the solution conditions normally investigated.

Mean densities (+/- SE) of D. appendiculata increased from May to July, and declined thereafter. The species reproduced continuously from April (spring) to October (fall). The proportions of ovigerous to non-ovigerous females increased with temperature, from similar to 70% (April), when mean water temperature was 14.7 +/- 0.77 degrees C, to similar to 94% (July), when water temperature was at its peak (26.4 +/- 0.23 degrees C), before decreasing to 0% (November) when the temperature was 9.6 +/- 0.2 degrees C. The maximum body lengths of non-ovigerous (9.75 mm) and ovigerous (9.85 mm) females, and males (11.1 mm) were larger than values previously reported in a D. appendiculata population in Beaufort, North Carolina, USA. Large ovigerous females from an overwintering cohort produced juveniles in April, and then disappeared from the population by June, leaving behind small, less fecund ovigerous females belonging to a new generation to produce juveniles. Thus, ovigerous females were smaller in size in June (mean +/- SE: 4.8 +/- 0.2 mm) than in April (7.3 +/- 0.1 mm) and May (8.8 +/- 0.5 mm). Males outnumbered females from May to October, but the reverse was the case in April (p < 0.05). The D. appendiculata population in MCBs has a semi-annual, iteroparous life history, with a longevity of about 6 mo (spring breeder) and 9 mo (fall breeder).

Often, performance deficiencies are not evident until late in the development of the manufacturing process, which delays the beginning of production and may cause damage to parts that have already undergone costly manufacturing steps. The goal of this research is to determine if a robot can meet manufacturing requirements, how to optimally plan robot activities, and to monitor robot processes to track performance. To achieve this, representations of product and manufacturing information and robot capabilities should be carried through the design, process planning, production, and analysis phases. Standards for the exchange of this information have been developed, such as ISO 10303 Part 242 for semantic product and manufacturing information and device kinematics, and the Robot Operating System Industrial specification for robot modeling, path planning, and execution. This paper surveys the relevant technologies and standards needed to enable automated deployment of robots in new application areas.

Visualized by Gauss maps, we prove that the problem reduces to a minimization search where the global minimum is localized about the minimizing facet. Second, we highlight advantages of this planar datum, including the major advantage that the datum planes have full mechanical contact with the datum features in stable cases yet are automatically balanced for rocking conditions. These advantages make this definition appealing for standardization. C1 [Shakarji, Craig M.] NIST, Phys Measurement Lab, Gaithersburg, MD 20899 USA.

The fully model-driven process introduces new intricacies and complexities that must be addressed to facilitate the reproducibility of AM parts.

All machine tools degrade during operations, yet knowledge of that degradation is elusive; accurate detection of linear axis degradation is a manual and time-consuming process. Thus, manufacturers need automated and efficient methods to diagnose the condition of their machine tool linear axes without disruptions to production. Towards this end, a sensor-based method was developed to quickly estimate the performance degradation of linear axes. The multi-sensor-based method uses data from inclinometers, accelerometers, and rate gyroscopes to identify changes in linear and angular errors due to axis degradation. A linear axis testbed, developed for verification and validation of the sensor-based method, contains a linear axis and a reference laser-based system for measurement of the axis geometric performance. Comparison of the sensor-based results and the laser-based results shows that the sensorbased method is capable of detecting micrometer-level and microradian-level degradation of linear axes. Consequently, if a sensor box resides on a machine tool, then the degradation of the linear axes can be periodically measured and used to help optimize maintenance. C1 [Vogl, Gregory W.; Donmez, M.

The system utilizes direct multiplication of a 10 GHz signal derived from a commercial synthesizer to carve pulses from the laser, which are then iteratively chirped and compressed in two stages. After reducing the repetition rate of the resulting pulse train to 2.5 GHz using selective transmission through an electro-optic gate, propagation through highly-nonlinear fiber generates an octave- spanning supercontinuum spectrum. We discuss the impact of the noise of the modulation frequency on the coherence of the supercontinuum and discuss its mitigation. Close agreement between experiment and theory is shown throughout, and we use our ability to precisely model the experiment to propose an extension of the system to 20 GHz repetition rate.

The push-pull optical pumping technique is used to increase the number of atoms that participate to the clock transition, yielding a typical CPT resonance contrast of 25 % for a CPT linewidth of about 450 Hz. The clock short-term fractional frequency stability is measured to be 3 x 10(-13) tau(-1/2) up to 100 seconds averaging time, in correct agreement with the signal-to-noise ratio limit. The mid-term frequency stability results are currently mainly limited by laser power effects. The detection of high-contrast narrow Raman-Ramsey fringes is demonstrated with this setup by making the atoms interact with a light pulse sequence.

Owing to the anisotropic elasticity of single-crystal silicon the vertical acceleration sensitivity was minimized in situ by axially rotating the resonator with respect to the mounting frame. The control of the resonator temperature is greatly improved by using a combination of two thermal shields monitoring with several temperature sensors and employing low-thermal conductivity materials. The instability of the resonator stabilized laser was characterized by comparing with another low-noise system based on a 48 cm long room temperature cavity of PTB's strontium lattice clock resulting in a modified Allan deviation of 7x10(-17) at 100 s.

In addition to our lithographic process using contact printing with photomasks, which is our primary technique for the production of immersion gratings, we explored two alternative fabrication methods, direct-write electron beam and photo-lithography. We have investigated the application of antireflection (AR) coatings during our contact printing lithography method to reduce the effect of Fizeau fringes produced by the contact of the photomask on the photoresist surface. This AR coating reduces the amplitude of the periodic errors by a factor of 1.5. Electron beam (e-beam) patterning allows us to manufacture gratings that can be used in first order, with groove spacing down to 0.5 micrometer or smaller (2,000 grooves/mm), but could require significant e-beam write times of up to one week to pattern a full-sized grating. The University of Texas at Austin silicon diffractive optics group is working with Jet Propulsion Laboratory to develop an alternate e-beam method that employs chromium liftoff to reduce the write time by a factor of 10. We are working with the National Institute of Standards and Technology using laser writing to explore the possibility of creating very high quality gratings without the errors introduced during the contact-printing step. Both e-beam and laser patterning bypass the contact photolithography step and directly write the lines in photoresist on our silicon substrates, but require increased cost, time, and process complexity.

Conventional double integrating sphere systems have several limitations and are suboptimal for optical characterization of liquid and soft materials used in 3D printing. We propose a vertical double integrating sphere system and the associated reconstruction algorithms for optical characterization of phantom materials that simulate different human tissue components. The system characterizes absorption and scattering properties of liquid and solid phantom materials in an operating wavelength range from 400 nm to 1100 nm. Absorption and scattering properties of the phantoms are adjusted by adding titanium dioxide powder and India ink, respectively. Different material compositions are added in the phantoms and characterized by the vertical double integrating sphere system in order to simulate the human tissue properties. Our test results suggest that the vertical integrating sphere system is able to characterize optical properties of tissue-simulating phantoms without precipitation effect of the liquid samples or wrinkling effect of the soft phantoms during the optical measurement.

The scales are primarily intended for regular transmittance, mirrors, and solid surface scattering diffusers. The rapidly growing area of optical medical imaging needs a scale for volume scattering of diffuse materials that are used to mimic the optical properties of tissue. Such materials are used as phantoms to evaluate and validate instruments under development intended for clinical use. To address this need, a double-integrating sphere based instrument has been installed to measure the optical properties of tissue-mimicking phantoms. The basic system and methods have been described in previous papers. An important attribute in establishing a viable calibration service is the estimation of measurement uncertainties. The use of custom models and comparisons with other established scales enabled uncertainty measurements. Here, we describe the continuation of those efforts to advance the understanding of the uncertainties through two independent measurements: the bidirectional reflectance distribution function and the bidirectional transmittance distribution function of a commercially available solid biomedical phantom. A Monte Carlo-based model is used and the resulting optical properties are compared to the values provided by the phantom manufacturer.

We discuss the use of low frequency dielectric spectroscopy to detect, characterize and monitor changes in electrical defects present in the dielectrics of through silicon vias (TSV) for three dimensional (3D) interconnected integrated circuit devices, as the devices are subjected to fluctuating thermal loads. The observed changes in the electrical characteristics of the interconnects were traceable to changes in the chemistry of the isolation dielectric used in the TSV construction. The observed changes provide phenomenological insights into the practice of burn-in. The data also suggest that these "chemical defects" inherent in the 'as-manufactured' products may be responsible for some of the unexplained early reliability failures observed in TSV enabled 3D devices.

This creates new possibilities for the types and number of sample conditions that can be examined but simultaneously increases the demands in terms of sample preparation. Microfluidic-based sample preparation techniques have emerged as elegant alternatives that can be integrated directly into the experimental X-ray setup remedying several shortcomings of more traditional methods. We review the use of microfluidic devices in conjunction with X-ray measurements at synchrotron facilities in the context of 1) mapping large parameter spaces, 2) performing time resolved studies of mixing-induced kinetics, and 3) manipulating/processing samples in ways which are more demanding or not accessible on the macroscale. The review covers the past 15 years and focuses on applications where synchrotron data collection is performed in situ, i.e. directly on the microfluidic platform or on a sample jet from the microfluidic device. Considerations such as the choice of materials and microfluidic designs are addressed. The combination of microfluidic devices and measurements at large scale X-ray facilities is still emerging and far from mature, but it definitely offers an exciting array of new possibilities.

It is well know that the single heaviest component of a passenger vehicle is the body structure, thus has the greatest potential for significantly reducing the vehicles mass. Therefore, transitioning from steel based bodies to ones composed of lightweight materials, such as: aluminum, magnesium and advanced high strength steels are of great interest. However, with the introduction of these new materials comes with a new means of joining, where conventional methods do not work. Therefore, this work examines a novel joining technique, flow drill screwdriving which is a thermo-mechanical process for joining aluminum and dissimilar materials. The focus of this work is to examine the residual stress distribution in a joint, because mechanical behavior and joint quality are greatly affected by the residual stress. Neutron diffraction was used for the determination of the residual stress in two samples processed with low and high fastener force. The high penetration depth of neutron radiation allows for the determination of triaxial residual stress states inside the material without destruction of the sample. It was found that the stress field around the joint location is primarily in tension, which is problematic if external forces are applied near the joint. Therefore, additional stress measurements were conducted under applied load through a lap shear test. Two load levels were applied to determine the effects on stress concentrations around the proximity of the joint.

This difficulty is compounded by technologies developed without a good understanding of the capabilities and limitations of the manufacturing environment, especially within small-to-medium enterprises (SMEs). This paper describes industrial case studies conducted to identify the needs, priorities, and constraints of manufacturing SMEs in the areas of performance measurement, condition monitoring, diagnosis, and prognosis. These case studies focused on contract and original equipment manufacturers with less than 500 employees from several industrial sectors. Solution and equipment providers and National Institute of Standards and Technology (NIST) Hollings Manufacturing Extension Partnership (MEP) centers were also included. Each case study involved discussions with key shop-floor personnel as well as site visits with some participants. The case studies highlight SME's strong need for access to appropriate data to better understand and plan manufacturing operations. They also help define industrially-relevant use cases in several areas of manufacturing operations, including scheduling support, maintenance planning, resource budgeting, and workforce augmentation.

The Model-based Enterprise (MBE) uses MBD as a way to transition away from using traditional paper based drawings and documentation. As MBD grows in popularity, it is imperative to understand what information is needed in the transition from drawings to models so that models represent all the relevant information needed for processes to continue efficiently. Finding this information can help define what data is common amongst different models in different stages of the lifecycle, which could help establish a Common Information Model. The Common Information Model is a source that contains common information from domain specific elements amongst different aspects of the lifecycle. To help establish this Common Information Model, information about how models are used in industry within different workflows needs to be understood. To retrieve this information, a survey mechanism was administered to industry professionals from various sectors. Based on the results of the survey a Common Information Model could not be established. However, the results gave great insight that will help in further investigation of the Common Information Model.

Currently, vendors who provide the software applications that implement control solutions are isolated and relatively independent. Each such solution is designed to implement a specific task such as control, simulation, and optimization and only that task. It is not uncommon for vendors to use different mathematical formalisms and modeling tools that produce different data representations and formats. Moreover, instead of being modeled uniformly only once, the same knowledge is often modeled multiple times each time using a different, specialized abstraction. As a result, it is extremely difficult to integrate optimization with advanced process control. We believe that a recent standard, International Organization for Standardization (ISO) 15746, describes a data model that can facilitate that integration. In this paper, we demonstrate a novel method of integrating advanced process control using ISO 15746 with numerical optimization. The demonstration is based on a chemical-process-optimization problem, which resides at level 2 of the International Society of Automation (ISA) 95 architecture. The inputs to that optimization problem, which are captured in the ISO 15746 data model, come in two forms: goals from level 3 and feedback from level 1. We map these inputs, using this data model, to a population of a meta-model of the optimization problem for a chemical process. Serialization of the metamodel population provides input to a numerical optimization code of the optimization problem. The results of this integrated process, which is automated, provide the solution to the originally selected, level 2 optimization problem.

To ride this wave of innovation, manufacturing enterprises are changing how product definitions are communicated from paper to models. To achieve industry's vision of the Model-Based Enterprise (MBE), the MBE strategy must include model-based data interoperability from design to manufacturing and quality in the supply chain. The Model-Based Definition (MBD) is created by the original equipment manufacturer (OEM) using Computer Aided Design (CAD) tools. This information is then shared with the supplier so that they can manufacture and inspect the physical parts. Today, suppliers predominantly use Computer Aided Manufacturing (CAM) and Coordinate Measuring Machine (CMM) models for these tasks. Traditionally, the OEM has provided design data to the supplier in the form of two-dimensional (2D) drawings, but may also include a three-dimensional (3D)-shape-geometry model, often in a standards based format such as ISO 10303-203:2011 (STEP AP203). The supplier then creates the respective CAM and CMM models and machine programs to produce and inspect the parts. In the MBE vision for model-based data exchange, the CAD model must include product-and-manufacturing information (PMI) in addition to the shape geometry. Today's CAD tools can generate models with embedded PMI. And, with the emergence of STEP AP242, a standards-based model with embedded PMI can now be shared downstream. The on-going research detailed in this paper seeks to investigate three concepts. First, that the ability to utilize a STEP AP242 model with embedded PM! for CAD-to-CAM and CAD-to-CMM data exchange is possible and valuable to the overall goal of a more efficient process. Second, the research identifies gaps in tools, standards, and processes that inhibit industry's ability to cost-effectively achieve model-based-data interoperability in the pursuit of the MBE vision. Finally, it also seeks to explore the interaction between CAD and CMM processes and determine if the concept of feedback from CAM and CMM back to CAD is feasible. The main goal of our study is to test the hypothesis that model-based-data interoperability from CAD-to-CAM and CAD-to-CMM is feasible through standards-based integration. This paper presents several barriers to model-based-data interoperability. Overall, the project team demonstrated the exchange of product definition data between CAD, CAM, and CMM systems using standards based methods. While gaps in standards coverage were identified, the gaps should not stop industry's progress toward MBE. The results of our study provide evidence in support of an open-standards method to model-based-data interoperability, which would provide maximum value and impact to industry.

Often overlooked, information on model uncertainty is required for validation of AM models, qualification of AM-produced parts, and uncertainty management. This paper presents a discussion on the origin and propagation of uncertainty in Laser Powder Bed Fusion (L-PBF) models. Four sources of uncertainty are identified: modeling assumptions, unknown simulation parameters, numerical approximations, and measurement error in calibration data. Techniques to quantify uncertainty in each source are presented briefly, along with estimation algorithms to diminish prediction uncertainty with the incorporation of online measurements. The methods are illustrated with a case study based on a transient, stochastic thermal model designed for melt pool width predictions. Model uncertainty is quantified for single track experiments and the effect of online estimation in overhanging structures is studied via simulation. The application of these concepts to estimation and control of the L-PBF process is suggested. C1 [Lopez, Felipe] Univ Texas Austin, Dept Mech Engn, Austin, TX 78712 USA.

In discrete parts manufacturing, factory machine monitoring has been difficult, due primarily to closed, proprietary automation equipment that make integration difficult. Recently, there has been a push in applying the data acquisition concepts of MTConnect to the real-time acquisition of machine status data. MTConnect is an open, free specification aimed at overcoming the "Islands of Automation" dilemma on the shop floor. With automated asset analysis, manufacturers can improve production to become lean, efficient, and effective. The focus of this paper will be on the deployment of MTConnect to collect real-time machine status to automate asset management. In addition, we will leverage the ISO 22400 standard, which defines an asset and quantifies asset performance metrics. In conjunction with these goals, the deployment of MTConnect in a large aerospace manufacturing facility will be studied with emphasis on asset management and understanding the impact of machine Overall Equipment Effectiveness (OEE) on manufacturing.

TI Habitat Use in a Depleted Population of Winter Flounder: Insights into Impediments to Population Recovery SO TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY LA English DT Article ID PSEUDOPLEURONECTES-AMERICANUS; PLEURONECTES-AMERICANUS; ESTUARINE; PREDATION; IDENTIFICATION; DISTRIBUTIONS; TEMPERATURES; FLATFISHES; ABUNDANCE; FISHES AB The distribution and demographics of a population of Winter Flounder Pseudopleuronectes americanus were examined for changes related to habitat quality over a fishery-independent survey period of 29 years, encompassing an 82% decline in abundance. We tested for spatial and temporal variation in indicators of fitness to determine whether they revealed likely processes that resulted in the observed patterns of habitat use. We also assessed temporal changes in fitness and inferred changes in habitat quality associated with population decline. We focused on the condition of postspawn (resting) mature and immature fish of both sexes during a critical period of spring feeding prior to summer migration. Analysis of variance of individual condition indices (log(10)[length]-log(10)[weight] regression residuals) by sex/maturity group and time period identified consistent and significant differences among six survey strata. Highest condition indices were observed for fish that were captured in shallow (<18-m) mud, sand, and transitional bottom sediment and deep (>18-m) mud areas, collectively classified as high-quality habitat. The proportion of the population that occupied high-quality habitat remained unchanged at approximately 60% over the time series. As abundance decreased, condition decreased in mature females, increased in immature fish of both sexes, and was mixed in mature males. Additionally, the proportion mature at length shifted significantly upward for both sexes, the back-calculated lengths at ages 2 and 3 increased for mature individuals, and the estimated winter growth declined for age-3 mature and immature females. The results suggested increased competition for prey among mature fish and increased predation pressure on smaller fish. This Winter Flounder population may be responding to an increase in the abundance of competing mid-Atlantic species, which was brought about by increasing water temperature. These second-order effects may have chronically hindered Winter Flounder reproduction and therefore stock rebuilding, especially in areas of low-quality habitat.

TI Differential Predictors of Adult versus Juvenile Distributions of Two Coastal Pelagic, Surf Zone Fishes along the Northern Gulf of Mexico SO TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY LA English DT Article ID TRACHINOTUS-CAROLINUS; SPANISH MACKEREL; ABUNDANCE; ATLANTIC; INDEXES; POMPANO; MODELS AB As coastal human populations increase and offshore fishery regulations become more stringent in the northern Gulf of Mexico, nearshore fisheries may be subjected to increased exploitation. Spanish Mackerel Scomberomorus maculatus and Florida Pompano Trachinotus carolinus are two nearshore, coastal migratory pelagic species vulnerable to undergoing changes in fishing pressure; however, information is incomplete in regards to understanding their current distributions and movement patterns, both of which are important for effective fishery management. We used a 2-year (2011-2012) gill-net and seine survey to assess surf zone distributions of Spanish Mackerel and Florida Pompano in the northern Gulf of Mexico (Horn Island, Mississippi, to Pensacola, Florida). Unbiased catch-per-unit-effort estimates (by the delta method) were greatest in Alabama and during spring months. Lowest catches occurred during the warm summer months. Overall, subadult-adult Spanish Mackerel presence could be predicted (using a delta-lognormal general linear model) by geographic area, beach habitat, and depth. Florida Pompano presence could be predicted by month and beach habitat. For both species, the abundance could not be predicted by any of the examined variables. Juvenile Florida Pompano presence, contrastingly, could be predicted by month and salinity, and abundance by month and water temperature. Both species had spatio-temporal variability in distribution and catch rates, but beach habitat appeared to be a better predictor for subadults and adults of both species, whereas month and salinity were better predictors for juvenile Florida Pompano catches. Greater catches generally corresponded with proposed migration patterns but also suggest that individuals, at least temporarily, leave the surf zone during the day in the warm summer months. Furthermore, although legal-sized individuals of both species can co-occur in the surf zone in the northern Gulf of Mexico, the increase in Spanish Mackerel presence with depth suggests that Spanish Mackerel fisheries could potentially move further offshore to avoid user conflict with Florida Pompano fisheries.

This methodology is applied to study the effect of PBTI stress on the density of ultra-fast electron traps (with 500 ps to 5 ns characteristic capture/emission times) in a high-k/Si nMOSFET. It is shown, that in spite of an observed increase of timing jitter after PBTI stress, this increase may not be correlated with an increasing density of interface traps. Rather, it is solely caused by a V-T shift which simply decreases the output signal amplitude. The results indicate that ultra-fast (presumably interface) traps may not be affected by PBTI stress.

If these field sources are separable in time or frequency, they can be demultiplexed with a single probe antenna and time gating or bandpass filtering. Spectrum-sharing coexistence testing, however, may deal with simultaneous co-channel radiation. Communication channels may realize orthogonality in signal modulation or coding, for example, instead of time or frequency. These signals need an alternative to time or frequency as a basis to discriminate between signals in tests. We explore here distributed multi-probe detection as a means to address this problem. Simultaneous coherent detection of quadrature baseband at multiple probes provides degrees of freedom necessary to decompose modulated signals with different origins in space. The approximately deterministic simple propagation behavior in an anechoic chamber allows us to estimate channel delay, phase shift, and attenuation parameters between each combination of probes and DUTs. These parameters are sufficient to extrapolate a transfer matrix across frequency that we invert to compute a weighting matrix that deembeds the received superposition of DUT waveforms. We demonstrate experiments that demultiplex three DUTs: a 802.11n Wi-Fi link pair and a source of LTE traffic, all in overlapping channels near 2.4 GHz. The demultiplexed channels show clearly the channel occupancy of each DUT without time-gating or frequency filtering.

Although this system has been operated in a scanning mode in the past, for this application, the system is operated in a vertically pointing mode and delivers a time series of vertical velocity profiles. By cooperating the Doppler lidar with other instruments, including a back scatter lidar, and a microwave radiometer, models of atmospheric stability can be tested, opening up an exciting path for researchers, applied scientists and engineers to discover unique phenomena related to fundamental atmospheric science processes. A consistent set of retrievals between each of these instruments emphasizes the utility for such a network of instruments to better characterize the turbulent atmospheric urban boundary layers which is expected to offer a useful capability for assessing and improving models that are in great need of such ground truth.

An important aspect of providing this wide range of meteorological data is to properly characterize the uncertainty associated with these measurements. With the above intent in mind, the Lidar Uncertainty Measurement Experiment (LUMEX) was conducted at Erie, Colorado during the period June 23rd to July 13th, 2014. The major goals of this experiment were the following: 1. Characterize sampling error for vertical velocity statistics 2. Analyze sensitivities of different Doppler lidar systems 3. Compare various single and dual Doppler retrieval techniques 4. Characterize error of spatial representativeness for separation distances up to 3 km 5. Validate turbulence analysis techniques and retrievals from Doppler lidars This experiment brought together 5 Doppler lidars, both commercial and research grade, for a period of three weeks for a comprehensive inter-comparison study. The Doppler lidars were deployed at the Boulder Atmospheric Observatory (BAO) site in Erie, site of a 300 m meteorological tower. This tower was instrumented with six sonic anemometers at levels from 50 m to 300 m with 50 m vertical spacing. A brief overview of the experiment outline and deployment will be presented. Results from the sampling error analysis and its implications on scanning strategy will be discussed.

Moreover, they are also a security and safety concern because of possible risk of fire/explosion or toxicity. This study presents gas concentration measurements using a quantum cascade laser open path system (QCLOPS). The system retrieves the path averaged concentration of N2O and CH4 by collecting the backscattered light from a scattering target. The gas concentration measurements have a high temporal resolution (68 ms) and are achieved at sufficient range (up to 40 m, similar to 130 feet) with a detection limit of 2.6 ppm CH4 and 0.4 ppm for N2O. Given these characteristics, this system is promising for mobile/multidirectional remote detection and evaluation of gas leaks. The instrument is monostatic with a tunable QCL emitting at similar to 7.7 mu m wavelength range. The backscattered radiation is collected by a Newtonian telescope and focused on an infrared light detector. Puffs of N2O and CH4 are released along the optical path to simulate a gas leak. The measured absorption spectrum is obtained using the thermal intra-pulse frequency chirped DFB QCL and is analyzed to obtain path averaged gas concentrations.

The Uintah Basin is a booming oil and gas producing region that often suffers from very high wintertime ozone concentrations. Clark County experiences violations of the US ozone standard primarily in spring and early summer despite a lack of any major local pollution sources. TOPAZ lidar observations, in conjunction with surface in situ measurements and model results, provided strong evidence that the high wintertime ozone concentrations in the Uintah Basin are primarily driven by local emissions associated with oil and gas exploration, whereas the Clark County ozone exceedances are often caused by ozone-rich air that is transported from the lower stratosphere all the way down to the earth's surface.

We also show cases of such aloft aerosol plumes intrusion and mixing into the boundary layer (PBL) and the impact on local air quality. Range-resolved monthly occurrence frequency and modification of local aerosol optical properties are presented. The NOAA-HYSPLIT cluster analysis indicates 6 main transport paths; and the optical properties (optical depth-AOD, Angstrom exponent-AE and single scatter albedo-SSA) of aerosol for each cluster are characterized. We further illustrate the impact of these aloft plumes on the satellite MODIS estimate of ground PM2.5 levels and observe that when the aloft plumes-layer AODs are filtered out using lidar, the correlation of MODIS AOD-PM2.5 can be much improved.

The system outputs include neutral density, winds, temperature, composition, and the satellite drag derived from these parameters. This modeling tool is called the Atmospheric Density Assimilation Model or ADAM. ADAM is based on three state-of-the-art coupled models of the thermosphere-ionosphere running in real-time and uses assimilative techniques to produce a thermospheric nowcast. ADAM will also produce 72 hour predictions of the global thermosphere-ionosphere system using the now cast as the initial condition and using near real-time and predicted space weather data and indices as the inputs. We show here that the model drag nowcast is comparable to the current state-of-the-art empirical models even in a non assimilative mode. We also show preliminary results of lower-boundary assimilation in the atmospheric model as well as the improvements from using an assimilative specification of storm-time energy inputs. With additional assimilation and tuning, we expect model performance to exceed the performance of current atmospheric models thus lowering the in-track orbit errors associated with Low Earth Orbit predictions.

In Hawaii (USA), green turtles have increased 5.4% yr(-1) since 1973, but fluctuations in census counts of nesting females make recovery diagnosis difficult. Evaluating demographic rates for temporal change and in relation to population density, and indicators of recruitment to sea turtle nesting populations, will ultimately improve population assessments. Using linear mixed and multistate open robust design models, we estimated the demographic indicators (DIs) of size at maturity, nester carapace length, breeding probability, and adult female survival using 3677 tagged nesting green turtles from 1973 to 2010 in Hawaii. To evaluate changes with density, we correlated the DIs with nesting female counts. We estimated size at maturity, assuming that newly tagged nesters are new recruits and that first-time nesters have statistically significant smaller carapace length than recaptures, but the difference in size was only similar to 0.5 cm. Mean nester carapace length (range: 89.21-91.69 cm) and breeding probability (range: 0.0766-0.444 yr(-1)) showed directional changes over time, suggesting shifts in age structure that could be due to recruitment. The top-ranked model predicted constant female survival over time (S = 0.929 yr(-1), 95% CI: 0.924-0.933, model likelihood = 1.00). Counter to our hypothesis based on density-dependence, breeding probability increases with increasing nester abundance. This work contributes to a growing set of studies evaluating sea turtle demography for temporal variability and is the first for Hawaiian green turtles. Our study demonstrates that some easily monitored demographic variables may serve as indicators of population change.

Monitoring of marine turtles at foraging grounds may detect changes in population trends that would take decades to be seen at nesting beaches. Mixed Stock Analysis using molecular markers provides a tool for estimating the origin of turtles sampled at foraging grounds. Here, we analysed mitochondrial DNA sequences of 90 immature green turtles at 2 foraging grounds in northwestern Sabah, Malaysia. We used data from 30 Indo-Pacific green turtle rookeries as the baseline for tracing the origin of turtles at the 2 foraging grounds. The inferred origins of turtles at the 2 locations were not different and indicated that the majority originated from 3 major populations in Southeast Asia, the Turtle Islands of Sarawak in northwestern Borneo (29%), the Turtle Islands Heritage Protected Area (TIHPA) (28%) and Peninsular Malaysia (25%). Previous analyses indicated a 1:4 female-biased sex ratio at the foraging grounds, and based on our results, this largely reflects the use of unshaded beach hatcheries at some of the source rookeries for decades, which resulted in mostly female hatchlings. This result is supported by differences in the origins of male and female turtles. The result suggests a greater proportion of males originating from Peninsular Malaysia and fewer males originating from Sarawak and possibly the TIHPA compared to females. We discuss the implications of hatchery practices that influence sex ratios of hatchlings and recommend future research to improve the management of marine turtles in the region.

Acoustic responses of whales to both naturally occurring and artificially increased levels of noise were documented during sound playback experimentation in San Ignacio Lagoon, Baja California Sur, Mexico. Nine acoustic parameters were examined and compared between experimental conditions: calling rates, call types, frequency range of calls (Hz), call peak frequencies (Hz), call received levels (dB re 1 mu Pa), call duration (s), percentage of calls showing frequency modulation, number of pulses per call, and call repetition rates (number of pulses s(-1)). Multiple acoustic strategies were employed by whales which enabled them to minimize the detrimental effect that noise had on their underwater signaling. When different sources of noise were added to their habitat, a corresponding increase was observed in calling rates, call received levels, frequency-modulated signals, number of pulses per call, and call repetition rates. Our results show that gray whales vary their calling behavior dependent upon the noise source, duration, and presentation. Acoustic responses to noise may also differ based on the behavioral activity of the whale (e.g. breeding, migrating, feeding) and on the habitat the whale is occupying (shallow lagoons, coastal or pelagic waters). Background noise (both natural and man-made) has a profound effect on the acoustic behavior of this coastal species and calling is modified to optimize signal transmission and reception. Whether these modifications ensure that effective communication takes place in higher noise situations, without causing detrimental effects to individuals in the long term, remains to be tested.

Besides shedding light on the coverage achieved by the proposed recommendations, we discuss implications towards aspects of test quality. One of them relates to the testing of a TLS implementation, where a system designer or tester should expand the TLS cipher suite registry and integrate the information back to the TLS implementation itself such that the (overall) testing effort is reduced.

Do two software assurance tools find the same set of bugs or different, complimentary sets? Can we guarantee that a new technique discovers all problems of this type? To answer such questions, we need a vastly improved way to describe classes of vulnerabilities and chains of failures. We present the Bugs Framework (BF), which raises the current realm of best efforts and useful heuristics. Our BF includes rigorous definitions and (static) attributes of bug classes, along with their related dynamic properties, such as proximate, secondary and tertiary causes, consequences and sites. The paper discusses the buffer overflow class, the injection class and the control of interaction frequency class, and provides examples of applying our BF taxonomy to describe particular vulnerabilities.

In this study, land based dissolved inorganic nitrogen (DIN) loading to LMEs was evaluated using a spatially explicit river export model (Global NEWS 2) for the year 2000 conditions and for a current trends analysis for the year 2050. Watershed export was aggregated by LME to estimate total DIN load and attribution to diffuse and point sources including natural biological fixation, agricultural biological fixation, fertilizer, manure, atmospheric deposition and sewage. Biological fixation in natural landscapes was the primary source of DIN to many LMEs, but in most (73%) LMEs, over half of the total DIN load was related to anthropogenic sources. Most of the anthropogenic DIN load across LMEs was related to agricultural sources especially fertilizer and manure. Fertilizer was the primary source of DIN to LMEs in most of Europe and Asia, while manure was the primary source in most of Central and South America. Agricultural biological fixation, sewage and atmospheric deposition in general supported a minor fraction of the DIN exported to LMEs although each was a dominant source to a few LMEs. If current trends continue, DIN export to coastal systems by 2050 relative to 2000 is predicted to increase by approximately 40-45% from Africa, South America, South Asia and Oceania. Almost half of the total global increase in DIN is from South Asia. Relatively smaller increases are predicted for North America, with slight decreases in Australia and Europe.

We propose an optimization-based computer-aided molecular design (CAMD) method to identify and select, from hundreds of thousands of possibilities, a few solvents of optimum performance for CO2 chemisorption processes, as measured by a comprehensive set of criteria. The first stage of the approach involves a fast screening stage where solvent structures are evaluated based on the simultaneous consideration of important pure component properties reflecting thermodynamic, kinetic, and sustainability behaviour. The impact of model uncertainty is considered through a systematic method that employs multiple models for the prediction of performance indices. In the second stage, high-performance solvents are further selected and evaluated using a more detailed thermodynamic model, i.e. the group-contribution statistical associating fluid theory for square well potentials (SAFT-gamma SW), to predict accurately the highly non-ideal chemical and phase equilibrium of the solvent-water-CO2 mixtures. The proposed CAMD method is applied to the design of novel molecular structures and to the screening of a data set of commercially available amines. New molecular structures and commercially-available compounds that have received little attention as CO2 capture solvents are successfully identified and assessed using the proposed approach. We recommend that these solvents should be given priority in experimental studies to identify new compounds.

While constant fields can be removed by calibration, stray fields are difficult to distinguish from ambient field variations. Putting two magnetometers on a long boom and solving for both the ambient and stray fields can help, but this gradiometer solution is more sensitive to noise than a single magnetometer. As shown here for the R-series Geostationary Operational Environmental Satellites (GOES-R), unless the stray fields are larger than the noise, simply averaging the two magnetometer readings gives a more accurate solution. If averaging is used, it may be worthwhile to estimate and remove stray fields explicitly. Models and estimation algorithms to do so are provided for solar array, arcjet and reaction wheel fields.

Models based on quantitative structure-activity relations (QSAR) provide some promise in this direction. However, QSAR models in the literature rarely provide uncertainty estimates in more detail than aggregated statistics such as the sensitivity and specificity of the model's predictions. Almost never is there a means of assessing the uncertainty in an individual prediction. Without an uncertainty estimate, it is impossible to assess the trustworthiness of any particular prediction, which leaves the model with a low utility for regulatory purposes. In the present work, a QSAR model with uncertainty estimates is used to predict biodegradability for a set of substances from a publicly available data set. Separation was performed using a partial least squares discriminant analysis model, and the uncertainty was estimated using bootstrapping. The uncertainty prediction allows for confidence intervals to be assigned to any of the model's predictions, allowing for a more complete assessment of the model than would be possible through a traditional statistical analysis. The results presented here are broadly applicable to other areas of modelling as well, because the calculation of the uncertainty will clearly demonstrate where additional tests are needed.

Both missions rely on high quality data, which could be compromised by radio frequency interference as spectrum becomes more valuable and more users appear. Radio frequency interference has been observed at operational radar sites and will only become more prevalent in the future. Fortunately, strategies to mitigate the effects of radio frequency interference exist and more are being developed.

Lett. 113, 045302 (2014)] this problem was analyzed for spinor condensates finding a complex level structure as in an early work [Bulgac and Efimov, Sov. J. Nucl. Phys. 22, 153 (1976)] in nuclear physics, and the impact of Efimov physics on the general form of the scattering observables was worked out. In this paper we discuss the appearance of novel families of Efimov states in the spinor three-body problem. C1 [Colussi, V. E.; D'Incao, J. P.] Univ Colorado, Dept Phys, Boulder, CO 80309 USA.

TI The effect of alignment on the electric mobility of soot SO AEROSOL SCIENCE AND TECHNOLOGY LA English DT Article ID TRANSITION REGIME; NONSPHERICAL PARTICLES; SHAPE; SIMULATION; AEROSOL; ORIENTATION; MORPHOLOGY; SCATTERING; FRICTION; NANORODS AB The effect of an aligning electric field on the mobility of both flame generated smoke and smolder generated smoke was studied. A pulsed differential mobility analyzer was used to study the alignment without changing the DMA flows. No detectable change in the mobility was observed for the smolder smoke, while a small but detectable effect of up to 5% decrease in the mobility diameter with increasing field was observed for the largest aggregates with a mobility diameter of 200nm. We modeled the friction coefficient tensor of soot fractal aggregates as an equivalent prolate spheroid to obtain the field induced mobility as a function of aspect ratio. The alignment probability distribution function was determined by computing the polarizability tensor for simulated fractal aggregates. One interesting result was the smallness of the prolate sphere aspect ratio of 1.2 to 1.3 compared to the much larger aspect ratio from TEM analysis and from the polarizability ratio. An explanation for the low value based on the contribution to the friction coefficient from the individual spheres for a fractal is given. Another interesting observation is the broadening of the mobility size distribution with decreasing field. This is shown to be related to the polydispersity of the aspect ratio. The fact that all three aggregate sizes appear to fit the same spheroid aspect ratio is interesting, and offers a first-order approach to describing transport properties of aggregates. An estimate of the rotation relaxation time of the fractal aggregate was made to verify that the rotation time was much shorter than the duration of the zero electric field period during each cycle.Copyright (c) 2016 American Association for Aerosol Research C1 [Li, Mingdong; Mulholland, George W.; Zachariah, Michael R.] Univ Maryland, Dept Chem & Biomol Engn, College Pk, MD 20742 USA.

Here, we discuss how we used conceptual models to promote interdisciplinary dialogue in support of integrated ecosystem assessments (IEAs) in the California Current ecosystem. Initial conceptualizations of the California Current IEA were based on the Driver-Pressure-State-Impact-Response framework. This initial framing was biophysically centered, with humans primarily incorporated as impacts on the system. We wished to move from a conceptualization that portrayed an antagonistic relationship between humans and nature to one that integrated humans and social systems into the IEA framework. We propose a new conceptualization of the California Current that functions across temporal and spatial scales, captures the diverse relationships that typify SESs, and highlights the need for interdisciplinary science. The development of this conceptualization reveals how our understanding of the place and role of people in the ecosystem changed over the course of the history of the California Current IEA. This conceptual model is adaptive and serves to ensure that interdisciplinarity will now be the standard for the California Current IEA and, perhaps, beyond.

Our social survey gathered information regarding attitudes and perceptions of changing social and environmental conditions in the Puget Sound Basin as well as views regarding possible management interventions. We mapped the survey data to US zip code regions and spatially overlaid the survey response data with existing geospatial data layers of biophysical conditions. Using mixed-effects logistic regression we examine the relationships between urban development trajectories and individual views about both environmental problems and possible policy responses. We found significant relationships between people's responses and the physical conditions within their residence zip code, as well as social variables, which illustrated the importance of developing new analytical approaches that consider the relationships between both biophysical and social features and individual attitudes about coastal environmental concerns.

The Pacific Coast Groundfish Fishery Social Study was designed to measure associated social changes and impacts on individuals and communities. Selected survey and interview data from the baseline data collection in 2010 and the first supplemental data collection effort in 2012 are aggregated at the community level and analyzed for initial signs of social change. Communities are sorted into top-, mid-, and low-tier communities based on the percentage of quota share (QS) permit owners that live in each community. A higher number of QS permit owners in a place is expected to result in relatively greater benefits to those communities. Questions analyzed include percent of income from fishing, multiple jobs worked, job stability, job satisfaction, standard of living, and how individuals were personally affected. Significant results for TOP-tier communities include increases in working multiple jobs, which may be negative or positive depending on the respondent, and improvements in job satisfaction. LOW-tier communities indicate significant improvements in standard of living. MID-tier communities appear to be in the middle, with no significant changes. Interview data indicate variation between owners, where some can fish their allocations and others need to lease more to fish.

Kasperski, Stephen TI The Impact of Access Restrictions on Fishery Income Diversification of US West Coast Fishermen SO COASTAL MANAGEMENT LA English DT Article DE catch shares; cooperatives; diversification; IFQ; limited entry AB Access to most fisheries on the US West Coast was essentially open prior to the mid-1970s when state licenses were first limited for salmon fisheries. Subsequently, licenses to most fisheries on the West Coast have been limited, and the numbers of licenses in many fisheries have been reduced with buy-back programs. More recently, catch share programs, which dedicate exclusive shares of catch to individuals or cooperatives, have been introduced in several sectors of the federally managed Pacific groundfish fishery. As access to fisheries has become more restricted, revenue diversification of West Coast fishing vessels has generally declined. This is a source of concern since diversification has been shown to reduce year-to-year variation in revenue and hence financial risk. However, catch share programs may create more security and stability in vessels' landings, which may offset effects of less diversification. Nevertheless, there may be a tradeoff between the efficiency gains enabled by restricting access and risk-reduction benefits associated with greater diversification.

Ocean wave energy is the least developed renewable energy source, despite having the highest energy per unit area. While many hurdles remain in developing wave energy, assessing potential conflicts and evaluating tradeoffs with the existing uses is essential. Marine planning encompasses a broad array of activities that take place in and affect large marine ecosystems, making it an ideal tool for evaluating wave energy resource use conflicts. In this study, we used a spatially explicit, open source decision support tool to evaluate wave energy facility development off the U.S. west coast. We then used this output to identify potential conflicts between wave energy facilities and the existing marine uses in the context of marine planning. We found that regions with the highest wave energy potential were distant from major cities and that infrastructure limitations (cable landing sites) restrict integration with the existing power grids. We also identified multiple potential conflicts, including commercial fishing, shipping and transportation, and marine conservation areas. While wave energy generation facilities may be economically viable, we must also incorporate costs associated with conflicts that arise with the existing marine uses.

Conceptual models are valuable tools for assimilating and simplifying this information to convey our understanding of ecosystem structure and functioning. Qualitative network models (QNMs) may allow us to conduct dynamic simulations of conceptual models to explore natural-social relationships, compare management strategies, and identify tradeoffs. We used previously developed QNM methods to perform simulations based on conceptual models of the California Current ecosystem's pelagic communities and related human activities and values. Assumptions about community structure and trophic interactions influenced the outcomes of the QNMs. In simulations where we applied unfavorable environmental conditions for production of salmon (Oncorhynchus spp.), intensive management actions only modestly mitigated declines experienced by salmon, but strongly constrained human activities. Moreover, the management actions had little effect on a human wellbeing attribute, sense of place. Sense of place was most strongly affected by a relatively small subset of all possible pair-wise interactions, although the relative influence of individual pair-wise interactions on sense of place grew more uniform as management actions were added, making it more difficult to trace effective management actions via specific mechanistic pathways. Future work will explore the importance of changing conceptual models and QNMs to represent management questions at finer spatial and temporal scales, and also examine finer representation of key ecological and social components.

We develop an age-structured food web model to explore some of the bioeconomic causes and consequences of fishing patterns. We illustrate some of the model behaviors using a food chain ecosystem, parameterized using species found in the northwest Atlantic. We explore the effects of different relationships between profitability (defined as total profit per unit fishing effort) and trophic level of the target species on ecosystem and fishing dynamics. Across the profitability scenarios we explore, different patterns in ecosystem and fishery dynamics emerge, with greater variability and depletion in ecosystem biomass, greater variability and less yield to the fishery, and more variable profit when lower trophic level are more profitable and subject to more intense fishing pressure. For all scenarios we calculate the mean trophic level of the catch (TLC) in each year (where trends in this metric are often assumed to be an indicator of fishing patterns and ecosystem health) and compare it with the mean trophic level of the ecosystem. The relationship between the TLC and trophic level of the ecosystem varies with the way in which the fishery develops, and also with the particular species, suggesting that the TLC may not be the best indicator of ecosystem dynamics.

Due to the combinatorial possibilities, there are millions of possible MOF structures. Aiming to exploit their exceptional tunability, surface areas and pore volumes, researchers have investigated MOFs for storage of gaseous fuels such as hydrogen for over a decade, but a suitable MOF to store hydrogen at ambient conditions has not yet been found. Here, we sought to rapidly determine the viability of using MOFs for hydrogen storage at recently proposed, cryogenic operating conditions. We constructed a large and structurally diverse set of 13 512 potential MOF structures based on 41 different topologies and used molecular simulation to determine MOF hydrogen deliverable capacities between 100 bar/77 K and 5 bar/160 K. The highest volumetric deliverable capacity was 57 g L-1 of MOF, which surpasses the 37 g L-1 of tank of the incumbent technology (compressing hydrogen to 700 bar at ambient temperature). To validate our in silico MOF construction method, we synthesized a new isoreticular family of MOFs (she-MOF-x series) based on the she topology, which is extremely rare among MOFs. To validate our hydrogen storage predictions, we activated and measured hydrogen adsorption on she-MOF-1 and NU-1103.

Design/methodology/approach - A common representation of tasks was used that is understood by all of the resources required for the job: robots, tooling, sensors and people. Findings - Using CRCL, a manufacturer can quickly develop robotic applications that meet customer demands for short turnaround, enable portability across a range of vendor equipment and maintain investments in application development through reuse. Originality/value - Industrial robots can perform motion with sub-millimeter repeatability when programmed using the teach-and-playback method. While effective, this method requires significant up-front time, tying up the robot and a person during the teaching phase.

TI Film morphology evolution during solvent vapor annealing of highly efficient small molecule donor/acceptor blends SO JOURNAL OF MATERIALS CHEMISTRY A LA English DT Article ID ORGANIC SOLAR-CELLS; FULLERENE; PERFORMANCE; CRYSTALLIZATION; POLY(3-HEXYLTHIOPHENE); PHOTOVOLTAICS AB Solution-processable small molecule photovoltaics based on the novel molecular donor, benzodithiophene terthiophene rhodanine (BTR), recently have shown maximum power conversion efficiencies above 8% for active layer thicknesses up to 400 nm, using post process solvent vapor annealing (SVA) with tetrahydrofuran (THF). Here we report an in situ study on the morphology evolution during SVA using the moderate solvent THF and the good solvent chloroform (CF). The combination of real-time grazing incidence X-ray diffraction (GIXD) and grazing incidence small angle X-ray scattering (GISAXS) allows us to draw a complete picture of the evolution of crystallinity and phase purity during post process annealing. We find that the relative crystallinity compared to the as-cast films is only modestly affected by SVA and solvent choice. However, both the phase purity and the characteristic domain sizes within the film vary significantly and are controlled by the solvent quality as well as exposure time. Using THF, films with high phase purity and desirable characteristic length scales of about 30 nm can be achieved, while the use of CF rapidly leads to excessive film coarsening and less preferable domain sizes on the order of 60 nm, too large for optimized charge separation.

These vectors-which were available every 10 minutes-have been quality controlled, error characterised and assimilated into the Australian Bureau of Meteorology's next generation operational regional forecast model as part of the new operational database. Results from this study indicate that this high temporal resolution imagery has the ability to produce high spatial and temporal density atmospheric motion vectors, and the quality of these vectors is such that they have the potential to improve numerical analysis and prognosis.

The 2015 experiment was conducted with 21 subjects, for shift of Duv (chromaticity shifts above and below the Planckian locus), using the same procedures as the 2013 experiment but minimizing the changes in gamut area in each pair of lights compared so that only the effects of chromaticity would be evaluated. The results showed that the lights with D-uv approximate to -0.015 on the average, nearly the same as the results in 2013, appeared the most natural at all correlated color temperatures.

This article communicates the results of the first version of the MAP in which 118 worldwide laboratories participated. Statistical analysis of how the laboratories' measurements compared to NIST's measurements are presented. In general, all the laboratory results are within +/- 4 % for total luminous flux and luminous efficacy measurements. The discussion provides reasons for any discrepancies or large uncertainty intervals found in the data. A major finding was that measurement differences of RMS current had a larger standard deviation and number of outliers than expected. Two possible explanations are (1) the discrepancies are due to issues with using 4-pole sockets, and (2) the large deviation is caused by some solid state lamps being sensitive to impedance and slew rate of AC power supplies.

GP CIE TI M/P RATIO METHOD FOR MESOPIC LUMINANCE MEASUREMENT SO PROCEEDINGS OF CIE 2016 LIGHTING QUALITY AND ENERGY EFFICIENCY LA English DT Proceedings Paper CT CIE Conference on Lighting Quality and Energy Efficiency CY MAR 03-05, 2016 CL Melbourne, AUSTRALIA SP Int Commiss Illuminat AB An approximate method for mesopic photometry measurements, named mesopic/photopic (M/P) ratio method, is proposed. It assumes that scotopic/photopic (S/P) ratio of the adaptation field and that of the test object are the same as the S/P ratio of the light sources used in the lighting installation. While this assumption enables in-situ measurements that only require conventional luminance meters with V(lambda) detector, it causes some errors on the mesopic quantity measurements. Error simulations with a real road surface spectral reflectance data set were conducted to evaluate feasibility of the M/P ratio method. The error tends to be larger for lower adaptation luminance and higher S/P ratio of the source. Although the errors may or may not be significant depending on the overall uncertainties of the field measurements, applying a correction factor based on the road surface spectral reflectance can improve the accuracy of the M/P ratio method drastically.

During quiet times (100 nT), accuracy is defined as absolute mean plus 3 sigma error per axis. During storms (300 nT), accuracy is defined as absolute mean plus 2 sigma error per axis. Error comes both from outside the magnetometers, e.g. spacecraft fields and misalignments, as well as inside, e.g. zero offset and scale factor errors. Because zero offset and scale factor drift over time, it will be necessary to perform annual calibration maneuvers. To predict performance before launch, we have used Monte Carlo simulations and covariance analysis. The simulation offers greater modeling flexibility, but the analysis serves as a check on the results. With the proposed calibration regimen, both suggest that the magnetometer subsystem will meet its accuracy requirements. C1 [Carter, Delano] Thearality Inc, POB 12463, Glendale, AZ 85318 USA.

The first launch of the GOES-R series is planned for October 2016. The GOES-R series satellites and instruments are being developed by the National Aeronautics and Space Administration (NASA). One of the key instruments on the GOES-R series is the Advance Baseline Imager (ABI). The ABI is a multi-channel, visible through infrared, passive imaging radiometer. The ABI will provide moderate spatial and spectral resolution at high temporal and radiometric resolution to accurately monitor rapidly changing weather. Initial on-orbit calibration and performance characterization is crucial to establishing baseline used to maintain performance throughout mission life. A series of tests has been planned to establish the post launch performance and establish the parameters needed to process the data in the Ground Processing Algorithm. The large number of detectors for each channel required to provide the needed temporal coverage presents unique challenges for accurately calibrating ABI and minimizing striping. This paper discusses the planned tests to be performed on ABI over the six-month Post Launch Test period and the expected performance as it relates to ground tests.

The three instruments - Solar UltraViolet Imager (SUVI), Extreme ultraviolet and X-ray Irradiance Sensor (EXIS), and Space Environment In-Situ Suite (SEISS) provide the data needed as inputs for the product updates National Oceanic and Atmospheric Administration (NOAA) provides to the public. SUVI is a full-disk extreme ultraviolet imager enabling Active Region characterization, filament eruption, and flare detection. EXIS provides inputs to solar backgrounds/events impacting climate models. SEISS provides particle measurements over a wide energy-and-flux range that varies by several orders of magnitude and these data enable updates to spacecraft charge models for electrostatic discharge. EXIS and SEISS have been tested and calibrated end-to-end in ground test facilities around the United States. Due to the complexity of the SUVI design, data from component tests were used in a model to predict on-orbit performance. The ground tests and model updates provided inputs for designing the on-orbit calibration tests. A series of such tests have been planned for the Post-Launch Testing (PLT) of each of these instruments, and specific parameters have been identified that will be updated in the Ground Processing Algorithms, on-orbit parameter tables, or both. Some of SUVI and EXIS calibrations require slewing them off the Sun, while no such maneuvers are needed for SEISS. After a six-month PLT period the GOES-R is expected to be operational. The calibration details are presented in this paper. C1 [Tadikonda, Sivakumara S. K.] Constellation Software Engn Corp, 4640 Forbes Blvd,Suite 201, Lanham, MD 20706 USA.

In an effort to improve the VIIRS calibration, VIIRS has undergone a number of major look up table updates during this period. RSB bands such as M1 through M3 suggested higher solar diffuser degradation rate. Similarly, for higher wavelengths, even though the solar diffuser degradation is much smaller and even negligible for SWIR bands, bands such as M7 suffer from major degradation due to RTA throughput degradation. Even though the solar diffuser and mirror degradation is well characterized, the data quality needs to be independently validated to ensure that data are well within the specification. We have used on-orbit calibration/validation techniques such as extended SNOs to estimate the bias of these bands and quantify the radiometric performance since launch. Assuming MODIS as a standard reference, intercomparison was performed to analyze the VIIRS radiometric performance. It was observed that some of the VIIRS bands such as M5 and M7 suggest bias on the order of 1.5% or more for most of the time period since early launch. VIIRS bias trends keep changing over time which can be mainly correlated to calibration updates and instrument anomalies. Results on VIIRS on-orbit calibration performance and its bias since early launch will be presented during meeting to help users better understand the data quality and its impacts on broader scientific research and applications.

MODIS instrument was designed with stringent calibration requirements and comprehensive on-board calibration capability. In the reflective solar spectral region, Aqua MODIS has performed better than Terra MODIS and, therefore, has been chosen by the Global Space-based Inter'-Calibration System (GSICS) operational community as the calibration reference sensor in cross-sensor calibration and calibration inter-comparisons. For the same reason, it has also been used by a number of earth-observing sensors as their calibration reference. Considering that Aqua MODIS has already operated for nearly 14 years, it is essential to transfer its calibration to a follow-on reference sensor with a similar calibration capability and stable performance. The VIIRS is a follow-on instrument to MODIS and has many similar design features as MODIS, including their on-board calibrators (OBC). As a result, VIIRS is an ideal candidate to replace MODIS to serve as the future GSICS reference sensor. Since launch, the S-NPP VIIRS has already operated for more than 4 years and its overall performance has been extensively characterized and demonstrated to meet its overall design requirements. This paper provides an overview of Aqua MODIS and S-NPP VIIRS reflective solar bands (RSB) calibration methodologies and strategies, traceability, and their on-orbit performance. It describes and illustrates different methods and approaches that can be used to facilitate the calibration reference transfer, including the use of desert and Antarctic sites, deep convective clouds (DCC), and the lunar observations.

However, the lack of standardized methods for these measurements has often led to contradictory results. Our goal in this study was to examine the feasibility of using a standardized Caenorhabditis elegans growth and reproduction based toxicity test designed for use with dissolved chemicals to assess ENM toxicity. Sensitivity testing of seven key experimental factors identified by cause-and-effect analysis revealed that bacterial feed density and plate shaking had significant effects on growth inhibition by a reference toxicant, benzylcetyldimethylammonium chloride (BAC-C16). Bacterial density was inversely proportional to experimental EC50 values, while shaking the plates during the assay caused a substantial decrease in nematode growth and reproduction in control nematodes. Other factors such as bacterial viability, organism maintenance, and media type showed minimal effect on the test method. Using this assay with positively charged polystyrene nanoparticles (PSNPs) revealed that the variability in the PSNP EC50 values was larger compared to those of BAC-C16. Additionally, while media type and bacterial viability did not impact BAC-C16 toxicity, PSNP toxicity differed substantially when these parameters were changed. PSNPs were more toxic in K+ medium and S-basal compared to M9 and feeding nematodes with UV killed E. coli decreased toxicity of PSNPs. Test validity with ENMs and modifications that can be made to adapt the standard C. elegans toxicity assay for use with ENMs are discussed. C1 [Hanna, S. K.; Cooksey, G. A.; Dong, S.; Nelson, B.

While transformations of inorganic nanoparticles (NPs) have been investigated extensively, less attention has been focused on the direct impact of aqueous photochemical reactions on adsorbed organic macromolecules that form the NP corona and strongly influence the surface interactions and reactivity that affect NP transport, fate, and toxicity. Here, we assess the transformations of methoxy polyethylene glycol thiol (mPEGSH) coatings on gold NPs (AuNPs) under controlled UV irradiation. A decrease in the adsorbed layer thickness of polymer was observed within 24 h of UV irradiation, resulting in increased susceptibility of the transformed NPs to aggregation. Surface chemistry analyses, including X-ray photoelectron spectroscopy (XPS), showed loss of the ether groups but persistence of reduced S on the AuNP surface, indicative of a chain scission mechanism yielding different NP surface properties from that of either the initial PEGylated AuNP or the citrate-stabilized AuNP prior to coating with mPEGSH. The transformation of the chemisorbed polymer was compared to that of dissolved mPEGSH in the presence and absence of the Au NPs, as evaluated by liquid chromatography-mass spectrometry (LC-MS). In contrast to the NP-adsorbed coating, the primary observed transformation of the dissolved mPEGSH was thiol oxidation to disulfides without extensive chain scission. This study demonstrates that transformations of adsorbed macromolecular coatings must be considered to accurately predict NP attachment behavior, and hence transport, in environmental systems. Because the corona transformation was not predictable from that of the dissolved polymer, direct NP surface characterization is required to discern the fundamental reactions involved in the photochemical transformation of coatings after sorption to the NP surface.

This low sensitivity offers the attractive possibility of reducing the need for fully cryogenic systems for YJH-band work, offering the potential for "warm-pupil" instrumentation that nonetheless reduces detected thermal background to the level of dark current. However, residual sensitivity beyond the cutoff wavelength is not well characterized, and may preclude the implementation of such warm-pupil instruments. We describe an experiment to evaluate the long-wavelength sensitivity tail of a 1.7 mu m-cutoff HAWAII-2RG array using a thermal blocking filter. Our results suggest the possibility of measurable red sensitivity beyond similar to 2 mu m. Ongoing improvements will confirm and refine this measurement. The thermal blocking filter offers the prospect of warm-pupil NIR instrument operation, which is particularly valuable for cost-effective and efficient testing systems: it has facilitated NIR detector characterization and will enable crucial laboratory tests of laser frequency comb calibration systems and other NIR calibration sources.

We compare our approach against the TESLA protocol in a 2-day simulation scenario, showing a reduction of 15.82% and 47.29% in computational cost, sender and receiver respectively, and a cumulative reduction in the communication overhead.

TI A Hierarchical structure of key performance indicators for operation management and continuous improvement in production systems SO INTERNATIONAL JOURNAL OF PRODUCTION RESEARCH LA English DT Article DE key performance indicator (KPI); manufacturing operation management (MOM); continuous improvement (CI); production systems; dependency; relationship; ISO 22400 ID SERIAL PRODUCTION LINES; FLEXIBLE MANUFACTURING SYSTEMS; THROUGHPUT ANALYSIS; BOTTLENECKS; QUALITY; DESIGN; IMPROVABILITY; RESPECT; MODELS AB Key performance indicators (KPIs) are critical for manufacturing operation management and continuous improvement (CI). In modern manufacturing systems, KPIs are defined as a set of metrics to reflect operation performance, such as efficiency, throughput, availability, from productivity, quality and maintenance perspectives. Through continuous monitoring and measurement of KPIs, meaningful quantification and identification of different aspects of operation activities can be obtained, which enable and direct CI efforts. A set of 34 KPIs has been introduced in ISO 22400. However, the KPIs in a manufacturing system are not independent, and they may have intrinsic mutual relationships. The goal of this paper is to introduce a multi-level structure for identification and analysis of KPIs and their intrinsic relationships in production systems. Specifically, through such a hierarchical structure, we define and layer KPIs into levels of basic KPIs, comprehensive KPIs and their supporting metrics, and use it to investigate the relationships and dependencies between KPIs. Such a study can provide a useful tool for manufacturing engineers and managers to measure and utilize KPIs for CI. C1 [Kang, Ningxuan] Tsinghua Univ, Dept Ind Engn, Beijing, Peoples R China.

In many applications involving multivariate count data, individual variables are not only correlated to each other, but also over-dispersed. Traditional statistical monitoring methods for multivariate count data that assume simple statistical models fail to fit the data collected when the underlying process is under normal working state, also referred to as the in-control state. Therefore, we propose a monitoring scheme which is based on the Poisson-multivariate Gaussian mixed model. Although such models are quite flexible, efficient statistical monitoring schemes for such models have not been developed. In this paper, we develop likelihood ratio test-based monitoring schemes that are shown to be superior to standard multivariate statistical monitoring schemes. The key challenge in developing likelihood ratio test for the Poisson-multivariate Gaussian mixed models is that the likelihood function can only be calculated by multidimensional numerical integration. We tackle this issue using an approximation of this complex likelihood function. C1 [Das, Devashish; Zhou, Shiyu] Univ Wisconsin, Dept Ind & Syst Engn, Madison, WI USA.

The study suggests that VIIRS bias trends changes over time mainly due to calibration updates and anomalies. Results show nearly consistent biases of 1.7% for M5 (0.672 mu m) and 2% for M7 (0.865 mu m) throughout the mission. However, M1 (0.412 mu m) and M4 (0.555 mu m) biases are less consistent. While biases for both M1 and M4 fluctuates mostly around 0%, M1 shows most frequent short-term changes in bias trends, as high as 4%. When the bias trends are compared with VIIRS on-board-calibration-based gain trends, there exists a high correlation. In addition, the operational VIIRS data product of NOAA and the reprocessed NASA Land Product Evaluation and Test Element (PEATE) data were compared by trending the radiance ratio. The ratio trends show calibration differences that agree well with bias trends. The comparison of bias with F-factors and ratio trends indicates that the frequent changes observed in VIIRS bias trends are primarily caused by calibration updates and anomalies in VIIRS operational calibration. The study suggests that even though the operational VIIRS data archive meets the specification of +/-2% radiometric uncertainty, reprocessing can improve data quality needed for rigorous scientific applications.

We present measurements of the detector properties and noise data in a subset of a fielded multichroic array of AlMn transition-edge sensor (TES) detectors. In this array, the distribution of critical temperature T-c across detectors appears uniform at the percent level. The measured noise-equivalent power (NEP) distributions over similar to 1200 detectors are consistent with expectations. We find median NEPs of 4.0x10(-17) W/root Hz for low-band detectors and 6.2x10(-17) W/root Hz for high-band detectors under covered-window telescope test conditions with optical loading comparable to observing with precipitable water vapor similar to 0.5 mm. Lastly, we show the estimated detector optical efficiency, and demonstrate the ability to perform optical characterization over hundreds of detectors at once using a cryogenic blackbody source.

Using two seasons of data, we demonstrate scalar leakage of 0.01%. This is consistent with model expectations and an order of magnitude better than any previously-reported leakage. We constrain higher-order dipole and quadrupole leakage terms to be < 0.06% (95% confidence). Without any mitigation from scan cross-linking or boresight rotation, this corresponds to an upper limit on systematic errors in the tensor-to-scalar ratio r less than or similar to 0.01. The HWP significantly reduces temperature-to-polarization leakage systematic errors for ABS and shows the promise of fast polarization modulation with HWPs for future experiments.

Ideal detectors for such a surveyor do not yet exist. As a demonstration of one technique for approaching the ultra-low NEPs required by this surveyor, we present the design of an array of 96 350 pm KIDs that utilize phonon recycling to boost responsivity. Our KID array is fabricated with TiN deposited on a silicon-on-insulator (SOI) wafer, which is a 2 pm thick layer of silicon bonded to a thicker silicon wafer by a thin oxide layer. The thick silicon is etched away underneath the absorbers so that the inductors are suspended on just the 2 pm membrane. The intent is that quasiparticle recombination phonons are trapped in the thin membrane, thereby increasing their likelihood of being re-absorbed by the KID to break additional Cooper pairs and boost responsivity. We also present a Monte-Carlo simulation that predicts the amount of signal boost expected from phonon recycling given flexible detector geometries and illumination strategies. For our initial array geometry, the simulation predicts a small but likely measurable 50% boost in responsivity. C1 [Fyhrie, Adalyn; Glenn, Jason] Univ Colorado, 389 UCB, Boulder, CO 80309 USA.

The Balloon-borne Large Aperture Submillimeter Telescope for Polarimetry (BLASTPol) flew from Antarctica in 2010 and 2012 and produced degree-scale polarization maps of several nearby molecular clouds with arcminute resolution. The success of BLASTPol has motivated a next-generation instrument, BLAST-TNG, which will use more than 3000 linear polarization-sensitive microwave kinetic inductance detectors (MKIDs) combined with a 2.5 m diameter carbon fiber primary mirror to make diffraction-limited observations at 250, 350, and 500 mu m. With 16 times the mapping speed of BLASTPol, sub-arcminute resolution, and a longer flight time, BLAST-TNG will be able to examine nearby molecular clouds and the diffuse galactic dust polarization spectrum in unprecedented detail. The 250 mu m detector array has been integrated into the new cryogenic receiver, and is undergoing testing to establish the optical and polarization characteristics of the instrument. BLAST-TNG will demonstrate the effectiveness of kilo-pixel MKID arrays for applications in submillimeter astronomy. BLAST-TNG is scheduled to fly from Antarctica in December 2017 for 28 days and will be the first balloon-borne telescope to offer a quarter of the flight for "shared risk" observing by the community.

PIPER will map 85% of the sky at 200, 270, 350, and 600 GHz over a series of 8 conventional balloon flights from the northern and southern hemispheres. The first science flight will use two 32 x 40 arrays of backshort-under-grid transition edge sensors, multiplexed in the time domain, and maintained at 100 mK by a Continuous Adiabatic Demagnetization Refrigerator. Frontend cryogenic Variable-delay Polarization Modulators provide systematic control by rotating linear to circular polarization at 3 Hz. Twin telescopes allow PIPER to measure Stokes I, Q, U, and V simultaneously. The telescope is maintained at 1.5 K in an LHe bucket dewar. Cold optics and the lack of a warm window permit sensitivity at the sky-background limit. The ultimate science target is a limit on the tensor-to-scalar ratio of r similar to 0.007, from the reionization bump to l similar to 300.

Its focal plane consists of modularized tiles of antenna-coupled transition edge sensors (TESs), similar to those used in BICEP2 and the Keck Array. The increased per-receiver optical throughput compared to BICEP2/Keck Array, due to both its faster f/1.7 optics and the larger aperture, more than doubles the combined mapping speed of the BICEP/Keck program. The BICEP3 receiver was recently upgraded to a full complement of 20 tiles of detectors (2560 TESs) and is now beginning its second year of observation (and first science season) at the South Pole. We report on its current performance and observing plans. Given its high per-receiver throughput while maintaining the advantages of a compact design, BICEP3-class receivers are ideally suited as building blocks for a 3rd-generation CMB experiment, consisting of multiple receivers spanning 35 GHz to 270 GHz with total detector count in the tens of thousands. We present plans for such an array, the new "BICEP Array" that will replace the Keck Array at the South Pole, including design optimization, frequency coverage, and deployment/observing strategies.

The frequencies of the four CLASS telescopes, one at 38 GHz, two at 93 GHz, and one dichroic system at 145/217 GHz, are chosen to avoid spectral regions of high atmospheric emission and span the minimum of the polarized Galactic foregrounds: synchrotron emission at lower frequencies and dust emission at higher frequencies. Low-noise transition edge sensor detectors and a rapid front-end polarization modulator provide a unique combination of high sensitivity, stability, and control of systematics. The CLASS site, at 5200 m in the Chilean Atacama desert, allows for daily mapping of up to 70% of the sky and enables the characterization of CMB polarization at the largest angular scales. Using this combination of a broad frequency range, large sky coverage, control over systematics, and high sensitivity, CLASS will observe the reionization and recombination peaks of the CMB E- and B-mode power spectra. CLASS will make a cosmic variance limited measurement of the optical depth to reionization and will measure or place upper limits on the tensor-to-scalar ratio, r, down to a level of 0.01 (95% C.L.).

To achieve its science goals, Advanced ACTPol utilizes a larger readout multiplexing factor than any previous CMB experiment to measure detector arrays with approximately two thousand transition-edge sensor (TES) bolometers in each 150 mm detector wafer. We present the implementation and testing of the Advanced ACTPol time-division multiplexing readout architecture with a 64-row multiplexing factor. This includes testing of individual multichroic detector pixels and superconducting quantum interference device (SQUID) multiplexing chips as well as testing and optimizing of the integrated readout electronics. In particular, we describe the new automated multiplexing SQUID tuning procedure developed to select and optimize the thousands of SQUID parameters required to readout each Advanced ACTPol array. The multichroic detector pixels in each array use separate channels for each polarization and each of the two frequencies, such that four TESes must be read out per pixel. Challenges addressed include doubling the number of detectors per multiplexed readout channel compared to ACTPol and optimizing the Nyquist inductance to minimize detector and SQUID noise aliasing.

A primary science goal of SPIDER is to measure the large-scale B-mode polarization of the cosmic microwave background (CMB) in search of the cosmic-inflation, gravitational-wave signature. 280 GHz channels aid this science goal by constraining the level of B-mode contamination from galactic dust emission. We present the focal plane unit design, which consists of a 16x16 array of conical, corrugated feedhorns coupled to a monolithic detector array fabricated on a 150 mm diameter silicon wafer. Detector arrays are capable of polarimetric sensing via waveguide probe-coupling to a multiplexed array of transition-edge-sensor (TES) bolometers. The SPIDER receiver has three focal plane units at 280 GHz, which in total contains 765 spatial pixels and 1,530 polarization sensitive bolometers. By fabrication and measurement of single feedhorns, we demonstrate 14.7 degrees FHWM Gaussian-shaped beams with <1% ellipticity in a 30% fractional bandwidth centered at 280 GHz. We present electromagnetic simulations of the detection circuit, which show 94% band-averaged, single-polarization coupling efficiency, 3% reflection and 3% radiative loss. Lastly, we demonstrate a low thermal conductance bolometer, which is well-described by a simple TES model and exhibits an electrical noise equivalent power (NEP) = 2.6 x 10(-17) W/root Hz, consistent with the phonon noise prediction.

It is the latest in the BICEP/Keck Array series of CMB experiments located at the South Pole, which has provided the most stringent constraints on inflation to date. For the 2016 observing season, BICEP3 was outfitted with a full suite of 2400 optically coupled detectors operating at 95 GHz. In these proceedings we report on the far field beam performance using calibration data taken during the 2015-2016 summer deployment season in situ with a thermal chopped source. We generate high-fidelity per-detector beam maps, show the array-averaged beam profile, and characterize the differential beam response between co-located, orthogonally polarized detectors which contributes to the leading instrumental systematic in pair differencing experiments. We find that the levels of differential pointing, beamwidth, and ellipticity are similar to or lower than those measured for BICEP2 and Keck Array. The magnitude and distribution of BICEP3's differential beam mismatch - and the level to which temperature-to-polarization leakage may be marginalized over or subtracted in analysis - will inform the design of next-generation CMB experiments with many thousands of detectors.

ACTPol uses transition edge sensor bolometers coupled to orthomode transducers to measure both the temperature and polarization of the Cosmic Microwave Background (CMB). Calibration of the detector angles is a critical step in producing polarization maps of the CMB. Polarization angle offsets in the detector calibration can cause leakage in polarization from E to B modes and induce a spurious signal in the EB and TB cross correlations, which eliminates our ability to measure potential cosmological sources of EB and TB signals, such as cosmic birefringence. We calibrate the ACTPol detector angles by ray tracing the designed detector angle through the entire optical chain to determine the projection of each detector angle on the sky. The distribution of calibrated detector polarization angles are consistent with a global offset angle from zero when compared to the EB-nulling offset angle, the angle required to null the EB cross-correlation power spectrum. We present the optical modeling process. The detector angles can be cross checked through observations of known polarized sources, whether this be a galactic source or a laboratory reference standard. To cross check the ACTPol detector angles, we use a thin film polarization grid placed in front of the receiver of the telescope, between the receiver and the secondary reflector. Making use of a rapidly rotating half-wave plate (HWP) mount we spin the polarizing grid at a constant speed, polarizing and rotating the incoming atmospheric signal. The resulting sinusoidal signal is used to determine the detector angles. The optical modeling calibration was shown to be consistent with a global offset angle of zero when compared to EB nulling in the first ACTPol results and will continue to be a part of our calibration implementation. The first array of detectors for Advanced ACTPol, the next generation upgrade to ACTPol, will be deployed in 2016. We plan to continue using both techniques and compare them to astrophysical source measurements for the Advanced ACTPol polarization calibration.

The first AdvACT detector array, sensitive to both 150 and 230 GHz, is fabricated on a 150 mm diameter wafer and read out with a completely different scheme compared to ACTPol. Approximately 2000 TES bolometers are packed into the wafer leading to both a much denser detector density and readout circuitry. The demonstration of the assembly and integration of the AdvACT arrays is important for the next generation CMB experiments, which will continue to increase the pixel number and density. We present the detailed assembly process of the first AdvACT detector array.

AdvACT will employ four arrays of feedhorn-coupled, polarization sensitive multichroic detectors. To accommodate the higher pixel packing densities necessary to achieve AdvACT's sensitivity goals, we have developed and optimized wideband spline-profiled feedhorns for the AdvACT multichroic arrays that maximize coupling efficiency while carefully controlling polarization systematics.

Building on experience gained with the ACTPol detector arrays, AdvACT will utilize various new technologies, including 150 mm detector wafers equipped with multichroic pixels, allowing for a more densely packed focal plane. Each set of detectors includes a feedhorn array of stacked silicon wafers which form a spline profile leading to each pixel. This is then followed by a waveguide interface plate, detector wafer, back short cavity plate, and backshort cap. Each array is housed in a custom designed structure manufactured from high purity copper and then gold plated. In addition to the detector array assembly, the array package also encloses cryogenic readout electronics. We present the full mechanical design of the AdvACT high frequency (HF) detector array package along with a detailed look at the detector array stack assemblies. This experiment will also make use of extensive hardware and software previously developed for ACT, which will be modified to incorporate the new AdvACT instruments. Therefore, we discuss the integration of all AdvACT arrays with pre-existing ACTPol infrastructure.

SuperSpec stands out from other direct-detection submm spectrometer technologies in that the detectors are coupled to a series of resonant filters along a single microwave feedline instead of using dispersive optics. SuperSpec makes use of kinetic inductance detectors (KIDs) to detect radiation in this filter bank. The small profile of this design makes SuperSpec a natural choice to produce a multi-object spectrometer for tomographic mapping or galaxy redshift surveys. We have recently fabricated a device that is a 50 channel subset of a full 280 channel filter bank, which would cover the 190- 310 GHz range at R = 275. Analysis of the data from this device informs us of the potential design modifications to enable a high-yield background-limited SuperSpec spectrometer. The results indicate that this subset filter bank can scale up to a full filter bank with only a few collisions in readout space and less than 20% variation in responsivity for the detectors. Additionally, the characterization of this and other prototype devices suggests that the noise performance is limited by generation-recombination noise. Finally, we find that the detectors are sufficiently sensitive for ground-based spectroscopy at R = 100, appropriate for tomographic mapping experiments. Further modifications are required to reach the background limit for R = 400, ideal for spectroscopy of individual galaxies.

Particular focus is placed on detecting trends in the annual ground freeze process portion of the ground thermal regime's daily temperature signature. A multivariate storage model from queuing theory is fit to a quantity of estimated daily depths of frozen soil. Statistical inference on a trend parameter is obtained by minimizing a weighted sum of squares of a sequence of daily one-step-ahead predictions. Standard errors for the trend estimates are presented. It is shown that the daily quantity of frozen ground experienced at these 11 sites exhibited a negative trend over the observation period.

Ma, Li TI Thermographic measurements of the commercial laser powder bed fusion process at NIST SO RAPID PROTOTYPING JOURNAL LA English DT Article DE Thermography; Emissivity; Laser powder bed fusion; Particle ejection ID QUALITY-CONTROL; HIGH-SPEED; TEMPERATURE; CAMERA AB Purpose - Quantitative understanding of the temperatures, gradients and heating/cooling rates in and around the melt pool in laser powder bed fusion (L-PBF) is essential for simulation, monitoring and controls development. The research presented here aims to detail experiment design and preliminary results of high speed, high magnification, in-situ thermographic monitoring setup on a commercial L-PBF system designed to capture temperatures and dynamic process phenomena. Design/methodology/approach - A custom door with angled viewport was designed for a commercial L-PBF system which allows close access of an infrared camera. Preliminary finite element simulations provided size, speed and scale requirements to design camera and optics setup to capture melt pool region temperatures at high magnification and frame rate speed. A custom thermal calibration allowed maximum measurable temperature range of 500 degrees C to 1,025 degrees C. Raw thermographic image data were converted to temperature assuming an emissivity of 0.5. Quantitative temperature results are provided with qualitative observations with discussion regarding the inherent challenges to future thermographic measurements and process monitoring. Findings - Isotherms around the melt pool change in size depending on the relative location of the laser spot with respect to the stripe edges. Locations near the edges of a stripe are cooled to lower temperatures than the center of a stripe. Temperature gradients are highly localized because of rough or powdery surface. At a specific location, temperatures rise from below the measurable temperature range to above (<550 degrees C to >1100 degrees C) within two frames (<1.11 m/s). Particle ejection is a notable phenomenon with measured ejection speeds >11.7 m/s. Originality/value - Several works are detailed in the Introduction of this paper that detail high-speed visible imaging (not thermal imaging) of custom or commercial LBPF processes, and lower-speed thermographic measurements for defect detection. However, no work could be found that provides calibrated, high-speed temperature data from a melt-pool monitoring configuration on a commercial L-PBF system. In addition, the paper elucidates several sources of measurement uncertainty (e.g. calibration, emissivity and time and spatial resolution), describes inherent measurement challenges based on observations of the thermal images and discusses on the implications to model validation and process monitoring and control.

From American Concrete Institute Committee 238 discussions and two international testing campaigns, it became clear that there is a need for a reference material specifically designed to assess the rheological properties of such granular materials. A newly developed series of reference materials, composed of corn syrup solution, fine limestone powder and glass beads, is presented here. Glass beads of 1 mm and 10 mm represent the sand and coarse aggregates respectively, while the mixture of corn syrup solution and limestone represents the paste. These systems simulating cement paste, mortar and concrete were tested using both rheological measurements and modelling. The synergy between experiment and modeling allowed for the elucidation of an effective slippage phenomenon near the moving surface, and suggested possibilities to reduce it. This paper explores what kind of measurements would be most suitable for the development of the reference materials as well as the results obtained using various rheometer geometries, such as parallel plate, coaxial, vane and double spiral geometries. A critical analysis of the measurement techniques is presented. C1 [Ferraris, Chiara F.; Martys, Nicos S.; George, William L.; Garboczi, Edward] NIST, Gaithersburg, MD 20899 USA.

Usually, several mixtures need to be prepared either using concrete or paste to determine the optimum High Range Water Reducer Admixture (HRWRA) dosage and type. The number of tests increases if the dosages of supplementary cementitious materials (SCMs) are also being optimized. To help reduce testing time and amount of materials used, a high-throughput micro rheometer is being designed that is based on an oscillatory parallel plate type rheometer. This novel device is a planar single-Degree of Freedom (DOF) motion stage based on Micro Electro Mechanical Systems (MEMS) fabrication methods. To meet the requirements for application to cement-based materials, a single-DOF motion stage is driven by an electro-thermal actuator that is designed to provide a shear stress of up to 60 Pa. The device is small and inexpensive to manufacture and several of them can be used in parallel to test various mixtures of paste at the same time. A vision sensor recognizes a set of predetermined patterns embedded on the motion stages for monitoring their motions. Data were obtained on a prototype by measuring the rheological properties of bentonite.

In this paper, results of a computational study of suspension flow in a pipe and a rheometer design using a four blade vane as an impellor are given. The computational method is based on the Smooth Particle Hydrodynamics approach. Flow fields and the spatial distribution of solid spherical inclusions for the case of pipe flow will be shown as a function of the matrix fluid properties, (including Newtonian, shear thinning and shear thickening), driving force, and volume fraction of particles. A strong effective slip phenomenon is shown for the case of a suspension with a shear thinning fluid matrix. Results will be compared to experiments. Aspects of shear induced migration in a vane rheometer and its effects on rheological measurements will be briefly discussed.

However, the specifications determine only the level of particulates and areal density of molecular layer on the surface, but the chemical composition of these contaminants are not specified. Here, we use a model to assess the impact on system quantum efficiency from possible contaminants that could accidentally transfer or cryopump to the detector during instrument or spacecraft testing and on orbit operation. Contaminant layers thin enough to meet typical specifications, < 0.5 mu gram/cm(2), have a negligible effect on the net quantum efficiency of the detector, provided that the contaminant does not react with the detector surface, Performance impacts from these contaminant plating onto the surface become important for thicknesses 5 - 50 mu gram/cm(2). Importantly, detectable change in the "ripple" of the anti reflection coating occurs at these coverages and can enhance the system quantum efficiency. This is a factor 10 less coverage for which loss from molecular absorption lines is important. Thus, should contamination be suspected during instrument test or flight, detailed modelling of the layer on the detector and response to very well known calibrations sources would be useful to determine the impact on detector performance.

The science goal of LiteBIRD is to measure the tensor-to-scaler ratio r with a precision of delta r < 10(-3), offering us a crucial test of the major large-single-field slow-roll inflation models. LiteBIRD is planned to conduct an all sky survey at the sun-earth second Lagrange point (L2) with an angular resolution of about 0.5 degrees to cover the multipole moment range of 2 <= l <= 200. We use focal plane detector arrays consisting of 2622 superconducting detectors to measure the frequency range from 40 to 400 GHz with the sensitivity of 2.5 mu K.arcmin. We report an overview and the status of the project, including the ongoing studies.

Because sensors have different purposes and measure different phenomena, it is necessary to know them and their different areas and domains of application so we can make a better use of their potential. This paper presents the identification and categorization of the main sensors used these days to build IoT applications, arranged in a taxonomy of application domains and sensor measurement types. To this purpose, we review the literature in order to identify IoT solutions, areas and domains of application and the main sensor types employed in these solutions. We hope this taxonomy can provide IoT designers, developers, and researchers with a snapshot of how sensors are currently used in the IoT application domains. Knowing the source devices is a key strategy to provide publication, discovery, sharing, reuse and integration of data/information within the IoT. We believe identifying and categorizing those sensors could be the first step to creating in the future a common communication model, which could be instantiated from each environmental context on the IoT.

TI Development of the Pacific Groundfish Trawl IFQ Market SO MARINE RESOURCE ECONOMICS LA English DT Article DE IFQ; ITQ; catch shares; quota markets; multispecies fishery ID QUOTAS AB In-season transferability of quota plays an important role in multispecies individual fishing quota (IFQ) systems since fishermen often need to acquire quota to balance incidental catch. The optimal utilization of quotas is thus dependent on development of an efficient quota market, but markets in multispecies IFQ fisheries develop slowly and may fail to perform efficiently even after several years. In 2011 an IFQ system was implemented for the Pacific groundfish trawl fishery in the US. After four years, the quota market does not appear to be yielding efficient prices for many species or distributing quota efficiently. I explore the structure and performance of the QP market and discuss the impediments to market efficiency. Drawing from theory and experience in other multi species IFQ systems, I discuss other quota distribution and catch-balancing mechanisms that can supplement and perhaps improve inefficient markets and enable higher quota utilization rates.

Here, we use thermally evaporated anthracene films as the sacrificial layer for graphene transfer onto an arbitrary substrate. We show that clean suspended graphene can be achieved via desorbing the anthracene layer at temperatures in the 100 degrees C to 150 degrees C range, followed by two sequential annealing steps for the final cleaning, using a Pt catalyst and activated carbon. The cleanliness of the suspended graphene membranes was analyzed employing the high surface sensitivity of low energy scanning electron microscopy and X-ray photoelectron spectroscopy. A quantitative comparison with two other commonly used transfer methods revealed the superiority of the anthracene approach to obtain a larger area of clean, suspended CVD graphene. Our graphene transfer method based on anthracene paves the way for integrating cleaner graphene in various types of complex devices, including the ones that are heat and humidity sensitive.

TI Practical limitations of aerosol separation by a tandem differential mobility analyzer-aerosol particle mass analyzer SO AEROSOL SCIENCE AND TECHNOLOGY LA English DT Article ID DIESEL EXHAUST PARTICLES; EFFECTIVE DENSITY; SOOT; CLASSIFICATION; SPHERES; DISTRIBUTIONS; SIMULATION; MORPHOLOGY; SYSTEM; REGIME AB A cavity ring-down spectrometer and condensation particle counter were used to investigate the limitations in the separation of singly and multiply charged aerosol particles by a tandem differential mobility analyzer ( DMA) and aerosol particle mass analyzer ( APM). The impact of particle polydispersity and morphology was investigated using three materials: nearly monodisperse polystyrene latex nanospheres ( PSL); polydisperse, nearly spherical ammonium sulfate ( AS), and polydisperse lacey fractal soot agglomerates. PSL and AS particles were easily resolved as a function of charge. For soot, the presence of multiply charged particles severely affects the isolation of the singly charged particles. In cases where the DMA-APM was unable to fully resolve the singly charged particles of interest, the peak mass deviated by up to 13% leading to errors in the mass specific extinction cross section of over 100%. For measurements of nonspherical particles, nonsymmetrical distributions of concentration as a function of mass were a sign of the presence of multiply charged particles. Under these conditions, the effects of multiply charged particles can be reduced by using a second charge neutralizer after the DMA and prior to the APM. Dilution of the aerosol stream serves to decrease the total number concentration of particles and does not remove the contributions of multiply charged particles.

Additional receivers on surrounding reef sites validated emigrations of tagged Red Snapper from the VPS-monitored sites. We tagged and released 86 Red Snapper and tracked 59 fish for extended periods (17 to 1,096 d). Telemetry tracking patterns identified fish status as active, emigrated, caught (F), or dead (M) at monthly intervals. At the end of the study, 17 fish had emigrated, 24 were caught by fishers, and 18 were active on VPS-monitored reef sites. For all years combined, annual fishing mortality was F = 0.44 (0.27-0.65, 95% confidence limit). In 2012, F = 0.72 (0.35-1.31) and was higher than other years, but the number of fish available for recapture at the start of the sportfishing season was low (n = 15). In 2013, F = 0.18 (0.07-0.42; n = 30), and in 2014, F = 0.42 (0.22-0.76; n = 28). One natural mortality (M) was detected in 2012, and M = 0.12 (0.02-0.69); no subsequent natural mortalities were detected in 2013 and 2014 (M = 0). Total instantaneous mortality (Z) for all years was Z = 0.48 (0.30-0.70). We attributed the low M to high fishing mortality but caution that sample sizes were small, which is typical of telemetry studies. The fates of 58 (98%) transmitter-tagged Red Snapper were successfully identified based on the VPS technology. Increases in F from 0.18 (2013) to 0.42 (2014) occurred when the length of the fishing seasonwas decreased (42 to 9 d) and indicated that fishers increased effort during the shortened fishing season, and the management goal of reducing catch may not have been achieved.

TI Nonlethal Batch Identification of Atlantic Salmon Using Coded Wire Tags SO NORTH AMERICAN JOURNAL OF FISHERIES MANAGEMENT LA English DT Editorial Material ID SURVIVAL; GROWTH; SMOLTS; IMPACT; SALAR; STOCK AB Hatchery fish are a valuable asset to and often an essential component of endangered species recovery programs. The recovery program for Atlantic Salmon Salmo salar in the Penobscot River, Maine, uses multiple life stages of hatchery fish. Correct identification of returning adults is vital to assess the contribution of each stocked life stage to overall Atlantic Salmon returns. We investigated the use of coded wire tags (CWTs) implanted into various body locations of salmon parr to determine whether the tags could be used as a nonlethal batch identifier after recapture. We tagged 200 (four groups of similar to 50) Atlantic Salmon parr with CWTs in four different anatomical locations (right and left dorsal and right and left adipose areas) using a Northwest Marine Technology (NMT) handheld multishot injector. We used an additional 51 nontagged parr as a control. We examined fish for CWTs using a NMT blue handheld wand and kept track of individuals using PIT tags. We monitored CWT recovery, correct identification of CWT location, growth rates for all tagged groups, and growth rates for the control group. Tag recovery was 94.7% at 28 months posttagging. Correct identification of CWT location improved with each sampling event to 88.3% at 28 months. Tag location did not affect growth rates, but we found a significant difference between tag location and tag recovery. The left dorsal and left adipose areas had the highest recovery rates. Tagging fish in different anatomical locations with CWTs can provide a minimally invasive batch mark when benign recovery is desired.

Implications for Use of a Natural Repellent to Guide Imperiled Pacific Lamprey into Fishways SO NORTH AMERICAN JOURNAL OF FISHERIES MANAGEMENT LA English DT Editorial Material ID LOWER COLUMBIA RIVER; PETROMYZON-MARINUS; BILE-ACIDS; MIGRATORY PHEROMONE; LAMPETRA-TRIDENTATA; FISHES; RESPONSES; IDENTIFICATION; ENVIRONMENT; MANAGEMENT AB Instream barriers affect anadromous lampreys worldwide by preventing access to spawning habitat, resulting in the decline of several species. Because lampreys rely heavily on olfactory cues to choose movement paths during upstream migration in rivers, the manipulation of these cues may be used to guide individuals into the vicinity of fish passage devices and thereby mitigate the impacts of barriers during migration. However, because experimentation with imperiled species presents significant legal and ethical challenges, use of a surrogate species that exhibits similar responses may prove very useful. Our laboratory study established that (1) the odor derived from dead Pacific Lamprey Entosphenus tridentatus elicits an avoidance response from invasive Sea Lamprey Petromyzon marinus from the Laurentian Great Lakes, and (2) the magnitude of this response does not differ from the conspecific alarm cue present in Sea Lamprey. By presenting the odor on the side of a river channel opposite a lamprey fish passage device, migrating lampreys of conservation concern may be guided to fishways, if the behavioral response to the cue has evolved in these taxa. Due to their availability and well-studied chemical communication system, Sea Lamprey may prove to be a useful surrogate for identifying and producing chemosensory cues for use in guiding Pacific Lampreys towards fish passage devices and away from intakes and screens.

This study addresses this gap by using a discrete-choice model to examine the determinants of the decision of quota shareholders to use hired skippers in the individual fishing quota (IFQ) fishery for Pacific Halibut Hippoglossus stenolepis in Alaska. Since the implementation of that Alaska IFQ program, there has been an increasing reliance on hired skippers by initial quota-share recipients in relationships that are often functionally equivalent to leasing. This has hampered the North Pacific Fishery Management Council's efforts to ultimately transition the IFQ catcher-vessel fleet to a group of owner-operators. This study shows that the probability of hiring a skipper is statistically significantly related to the residency and shareholdings of shareholders and identifies potential attributes of shareholdings, including quantity and diversity, which may contribute to more hired skipper use. This information may allow fishery managers to both predict the degree of such practices and to customize regulations that lead to preferred outcomes in program design or modification, as it relates to the IFQ program and other catch-share programs wherein leasing is a common practice prone to controversy.

In order to transfer the vacuum realization to artifacts in atmospheric pressure air, the effects of the sorption of atmospheric contaminants must either be corrected for or eliminated. NIST has constructed a system that directly compares a mass in vacuum to a mass in air, thereby eliminating the need for sorption correction. We describe the operation of this system and compare results to those obtained from sorption corrections.

State-of-the-art precision voltage-standard systems based on arrays of superconductive Josephson junctions can now provide quantum-accurate, intrinsically stable, programmable voltages at amplitudes greater than 10 V for dc voltages and up to 2 V rms for synthesized ac voltages such as sine waves and arbitrary waveforms. Various measurement techniques have been developed for ac measurement applications in the audio-frequency regime and for 60 Hz power metrology. I describe the key developments in Josephson circuits and in measurement techniques, and summarize their current performance and limitations for voltage metrology applications. In particular, I emphasize how the use of quantum-based systems, even when they produce apparently low-uncertainty and reproducible results, does not guarantee that the measurements are accurate. Finally, I briefly summarize how quantum-accurate, arbitrary waveform synthesis is being used to measure Boltzmann's constant by measuring the Johnson noise of a resistor at the triple-point of water, and how a practical electronic primary temperature standard might be realized with a quantum-based Johnson noise thermometer.

The work summarized herein describes metrological methods for use of radiation pressure forces to interconvert between mass, force and laser power. These experiments have the potential to allow the accurate measurement of laser from a calibrated mass or force and vice versa in a fashion traceable to the International System of Units (SI).

The radiometer will estimate the noise temperature of a device under test (DUT) based on comparison with room temperature and 77K noise standards. This is a standard physical approach in other NIST microwave radiometers. The radiometer is particularly amenable to performing noise temperature as well as noise parameter measurements for amplifier and transistor characterization. As wireless communications progresses towards millimeter wave systems, noise characterization of related components and subsystems becomes essential.

The ratio is a constant value, (pi/mu n(2))(2) and does not depend on electrical resistivity and other parameters. A simulation for dc current density to measure the two resistances was compared. Also, the two resistances were measured at dc and the measured resistance ratio is roughly in agreement with the calculated resistance ratio.

In part, this is due to both a lack of known biological markers of pansteatitis and a lack of suitable non-invasive assays capable of rapidly classifying the disease. Here, we propose the application of a point-of-care (POC) device using lipid-based test strips (total cholesterol (TC) and total triglyceride (TG)), for classifying pansteatitis status in the whole blood of pre-spawning Mozambique tilapia (Oreochromis mossambicus). Using the TC strips, the POC device was able to non-lethally classify the tilapia as either healthy or pansteatitis-affected; the sexes were examined independently because sexual dimorphism was observed for TC (males p = 0.0364, females chi(2) = 0.0007). No significant difference between healthy and pansteatitis-affected tilapia was observed using the TG strips. This is one of the first described applications of using POC devices for on-site environmental disease state testing. A discussion on the merits of using portable lipid-based analyzers as an in-field disease state diagnostic tool is provided. C1 [Bowden, John A.; Boggs, Ashley S.

A primary reason that Large-Scale Metrology continues to represent the research frontier is that technological advances introduced and perfected at a conventional scale face additional challenges which increase non-linearly with size. This necessitates new ways of considering the entire measuring process, resulting in the application of concepts such as virtual measuring processes and cyber-physical systems.

TI Tuning the bridging attraction between large hard particles by the softness of small microgels SO SOFT MATTER LA English DT Article ID SHORT-RANGE ATTRACTION; COLLOIDAL DISPERSIONS; PHASE-DIAGRAMS; POLYMER; GELATION; BEHAVIOR; STATES; MODEL; FLOCCULATION; TEMPERATURE AB In this study, the attraction between large hard polystyrene (PS) spheres is studied by using three types of small microgels as bridging agents. One is a purely soft poly(N-isopropylacrylamide) (PNIPAM) microgel, the other two have a non-deformable PS hard core surrounded by a soft PNIPAM shell but are different in the core-shell ratio. The affinity for bridging the large PS spheres is provided and thus affected by the PNIPAM constituent in the microgels. The bridging effects caused by the microgels can be indirectly incorporated into their influence on the effective attraction interaction between the large hard spheres, since the size of the microgels is very small in comparison to the size of the PS hard spheres. At a given volume fraction of large PS spheres, they behave essentially as hard spheres in the absence of small microgels. By gradually adding the microgels, the large spheres are connected to each other through the bridging of small particles until the attraction strength reaches a maximum value, after which adding more small particles slowly decreases the effective attraction strength and eventually the large particles disperse individually when saturated adsorption is achieved. The aggregation and gelation behaviors triggered by these three types of small microgels are compared and discussed. A way to tune the strength and range of the short-range attractive potential via changing the softness of bridging microgels (which can be achieved either by using core-shell microgels or by changing the temperature) is proposed.

Results show that the anomaly-based analysis approach can clearly reveal Sandy's structure evolution, including its interaction with other synoptic-scale systems as well as the intensification and extratropical transition (ET) processes. During its lifetime, Sandy experienced two consecutive periods of intensification caused by the merging of anomalous vortices on 27 and 29 October. The unusual left turn and the ET process prior to the landfall are respectively influenced by an anomalous anticyclone to the northeast and an anomalous cold vortex at the 300-850 hPa layer to the northwest, which is confirmed by the experiments using the generalised BAM.

Agile use of information is a cornerstone of data analytics, but analytical methods more generally, including model-based investigations of manufacturability and operations do not so easily benefit from this data. Rather than relating anonymous patterns of data to outcomes, these latter analytical methods are distinguished as relying on conceptual or physics-based models of the real world. Such models require careful consideration of the fitness of the data to the purpose of the analysis. Verification of these analyses, then, is a significant bottleneck. A related problem, that of ascertaining reproducible results in scientific claims, is being addressed through executable notebook technology. This paper proposes to use notebook technologies to address that bottleneck. It describes how this notebook technology, linked to internet-addressable ontologies and analytical metamodels, can be used to make model-based analytical methods more verifiable, and thus more effective for manufacturers.

Here, we report a detailed characterization of resistive switching in crystalline SURMOF films of around approximate to 10, approximate to 20 and approximate to 50 nm thicknesses. These demonstrated switching characteristics combined with the ability to deposit monolithically oriented crystalline HKUST-1 films with well-defined thicknesses in the nm-range on conductive substrates serving as bottom electrodes and to lithographically fabricate top-electrodes opens up the possibility to employ these metal-organic hybrid materials as solid state devices for potential nonvolatile resistive random access memory (RRAM) memory applications. MOF bipolar switching RRAM devices based on SURMOFs with thicknesses of 10 +/- 5 nm, 20 +/- 5 nm and 50 +/- 5 nm show exceptionally promising performance. The huge flexibility of MOF materials with regards to device applications is demonstrated by loading guest molecules into the pores of these framework materials. In the case of ferrocene infiltration, we show that the already impressive performance of the SURMOF-RRAM devices can be further improved. The results demonstrate the great potential of SURMOF thin films for the implementation of novel and scalable active materials for the next generation of digital processing and organic-based microelectronic devices.

I will also discuss progress in processing BCARS spectra to make them independent of excitation profile or non-resonant response, and directly comparable to spontaneous Raman spectra. I will also discuss progress on a new approach to time-domain BCARS that promises to significantly simplify and speed BCARS data acquisition.

These temporal and spatial ocean color changes require satellite validation for applications using bio-optical products to delineate diurnal processes. The diurnal color change and capability for satellite ocean color response were determined with in situ and satellite observations. Hourly variations in satellite ocean color are dependent on several properties which include: a) sensor characterization b) advection of water masses and c) diurnal response of biological and optical water properties. The in situ diurnal changes in ocean color in a dynamic turbid coastal region in the northern Gulf of Mexico were characterized using above water spectral radiometry from an AErosol RObotic NETwork (AERONET -WavCIS CSI-06) site that provides up to 8-10 observations per day (in 15-30 minute increments). These in situ diurnal changes were used to validate and quantify natural bio-optical fluctuations in satellite ocean color measurements. Satellite capability to detect changes in ocean color was characterized by using overlapping afternoon orbits of the VIIRS-NPP ocean color sensor within 100 minutes. Results show the capability of multiple satellite observations to monitor hourly color changes in dynamic coastal regions that are impacted by tides, re-suspension, and river plume dispersion. Hourly changes in satellite ocean color were validated with in situ observation on multiple occurrences during different times of the afternoon. Also, the spatial variability of VIIRS diurnal changes shows the occurrence and displacement of phytoplankton blooms and decay during the afternoon period. Results suggest that determining the temporal and spatial changes in a color / phytoplankton bloom from the morning to afternoon time period will require additional satellite coverage periods in the coastal zone.

The Advanced Himawari Imager (AHI) onboard H8 provides full-disk (FD) observations every 10 minutes, in 16 solar reflectance and thermal infrared (IR) bands, with spatial resolution at nadir of 0.5-1 km and 2 km, respectively. The NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) SST system, previously used with several polar-orbiting sensors, was adapted to process the AHI data. The AHI SST product is routinely validated against quality controlled in situ SSTs available from the NOAA in situ SST Quality monitor (iQuam). The product performance is monitored in the NOAA SST Quality Monitor (SQUAM) system. Typical validation statistics show a bias within +/- 0.2 K and standard deviation of 0.4-0.6 K. The ACSPO H8 SST is also compared with the NOAA heritage SST produced at OSPO from the Multifunctional Transport Satellite (MTSAT-2; renamed Himawari-7, or H7 after launch) and with another H8 SST produced by JAXA (Japan Aerospace Exploration Agency). This paper describes the ACSPO AHI SST processing and results of validation and comparisons. Work is underway to generate a reduced volume ACSPO AHI SST product L2C (collated in time; e.g., 1-hr instead of current 10-min) and/or L3C (additionally gridded in space). ACSPO AHI processing chain will be applied to the data of the Advanced Baseline Imager (ABI), which will be flown onboard the next generation US geostationary satellite, GOES-R, scheduled for launch in October 2016.

Their theoretical foundations were laid in the 1980s-1990s, during the era of the Advanced Very High Resolution Radiometers which have been flown onboard NOAA satellites since 1981. Consequently, the multi-channel and non-linear SST algorithms employ the bands centered at 3.7, 11 and 12 mu m, similar to available in AVHRR. More recent radiometers carry new bands located in the windows near 4 mu m, 8.5 mu m and 10 mu m, which may also be used for SST. Involving these bands in SST retrieval requires modifications to the regression SST equations. The paper describes a geeral approach to constructing SST regression equations for an arbitrary number of radiometric bands and explores the benefits of using extended sets of bands available with the Visible Infrared Imager Radiometer Suite (VIIRS) flown onboard the Suomi National Polar-orbiting Partnership (S-NPP) and to be flown onboard the follow-on Joint Polar Satellite System (JPSS) satellites, J1-J4, to be launched from 2017-2031; Moderate Resolution Imaging Spectroradiometers (MODIS) flown onboard Aqua and Terra satellites; and the Advanced Himawari Imager (AHI) flown onboard the Japanese Himawari-8 satellite (which in turn is a close proxy of the Advanced Baseline Imager (ABI) to be flown onboard the future Geostationary Operational Environmental Satellites - R Series (GOES-R) planned for launch in October 2016.

In general, peptides with inorganic affinity and specificity have been isolated from organisms and through biocombinatorial selection techniques (ie, phage and cell surface display). These peptides recognize and bind the inorganic surface through a series of noncovalent interactions, driven by both enthalpic and entropic contributions, wherein the biomolecules wrap the metallic nanoparticle structure. Through these interactions, modification of the inorganic surface can be accessed to drive the incorporation of significantly disordered surface metal atoms, which have been found to be highly catalytically active for a variety of chemical transformations. We have employed synthetic, site-directed mutagenesis studies to reveal localized binding effects of the peptide at the metallic nanoparticle structure to begin to identify the biological basis of control over biomimetic nanoparticle catalytic activity. The protocols described herein were used to fabricate and characterize peptide-capped nanoparticles in atomic resolution to identify peptide sequence effects on the surface structure of the materials, which can then be directly correlated to the catalytic activity to identify structure/ function relationships.

In the early 1980' s the dominant method for refining triangles was the red-green algorithm of Bank and Sherman. The red refinements are the desired refinements, but will result in an incompatible grid when used alone. The green refinements are used to recover compatibility for stability of the finite element discretization, and are removed before the next adaptive step. Prof. Bob Skeel raised the question as to whether it is possible to perform adaptive refinement of triangles without this complicated patching/unpatching process. As a result, a new triangle refinement method, called newest vertex bisection, was devised as an alternative to red-green refinement in the mid 1980' s. The new approach is simpler and maintains compatibility of the grid at all times, avoiding the patching/unpatching of the green refinement. We review the development of the newest vertex bisection method for adaptive refinement, and subsequent extensions of the method.

The single photons are generated through a recombination of an electron-hole pair formed by an electron from the conduction band and a hole from the valence band. When excited to the biexciton state quantum dots can provide pairs of photons emitted in a cascade. It has been shown that this biexciton-exciton cascade can deliver entangled pairs of photons. To achieve a deterministic generation of photon pairs from a quantum dot system one requires exciting it using a two-photon resonant excitation of the biexciton. Particularly, an efficient and coherent excitation of the biexciton requires the elimination of the single exciton probability amplitude in the excitation pulse and reaching the lowest possible degree of dephasing caused by the laser excitation. These two conditions impose contradictory demands on the excitation pulse-length and its intensity. We addressed this problem from a point of view that does not include interaction of the quantum dot with the semiconductor environment. We found an optimized operation regime for the system under consideration and provide guidelines on how to extend this study to other similar systems. In particular, our study shows that an optimal excitation process requires a trade-off between the biexciton binding energy and the excitation laser pulse length.

In box jellyfish (Cubozoa, Cnidaria), the mitochondrial genome is organized into 8 linear mito-chromosomes harboring between one and 4 genes each, including 2 extra protein-coding genes: mt-polB and orf314. Such an organization challenges the traditional view of mitochondrial DNA (mtDNA) expression in animals. In this study, we investigate the pattern of mitochondrial gene expression in the box jellyfish Alatina alata, as well as several key nuclear-encoded molecular pathways involved in the processing of mitochondrial gene transcription. Results: Read coverage of DNA-seq data is relatively uniform for all 8 mito-chromosomes, suggesting that each mito-chromosome is present in equimolar proportion in the mitochondrion. Comparison of DNA and RNA-seq based assemblies indicates that mito-chromosomes are transcribed into individual transcripts in which the beginning and ending are highly conserved. Expression levels for mt-polB and orf314 are similar to those of other mitochondrial-encoded genes, which provides further evidence for them having functional roles in the mitochondrion. Survey of the transcriptome suggests recognition of the mitochondrial tRNA-Met by the cytoplasmic aminoacyl-tRNA synthetase counterpart and C-to-U editing of the cytoplasmic tRNA-Trp after import into the mitochondrion. Moreover, several mitochondrial ribosomal proteins appear to be lost. Conclusions: This study represents the first survey of mitochondrial gene expression of the linear multi-chromosomal mtDNA in box jellyfish (Cubozoa). Future exploration of small RNAs and the proteome of the mitochondrion will test the hypotheses presented herein.

We observe temperature (T)-independent crossing points in the longitudinal resistivity rho(xx,) which are signatures of the insulator-quantumHall (I-QH) transition, in all three devices. Upon converting the raw data into longitudinal and Hall conductivities sigma(xx) and s sigma(xy), in the most disordered device, we observed a T-driven flow diagram approximated by the semi-circle law as well as the T-independent point in sigma(xy) near e(2)/h. We discuss our experimental results in the context of the evolution of the zero-energy Landau level at lowmagnetic fields B. We also compare the observed strongly insulating behaviour withmetallic behaviour and the absence of the I-QH transition in graphene on SiO2 prepared by mechanical exfoliation.

The coherent scattering intensity, containing structural information, and the incoherent scattering compete over a wide range of magnitude of scattering vector, q, specifically when q is larger than q* approximate to 1/R-g, where R-g is the radius of gyration of scatterer. Therefore, it is important to determine the incoherent scattering intensity exactly to perform an accurate structural analysis from SANS data when R-g is small, such as the aforementioned extracted coordination species. Although NPA is the best method for evaluating the incoherent scattering component for accurately determining the coherent scattering in SANS, this method is not used frequently in SANS data analysis because it is technically challenging. In this study, we successfully demonstrated that experimental determination of the incoherent scattering using NPA is suitable for sample systems containing a small scatterer with a weak coherent scattering intensity, such as extracted complexes in biphasic solvent extraction systems.

Wireless connections provide flexible access to a variety of field instruments and reduce network installation and maintenance costs. This serves as an incentive for the adoption of industrial wireless networks based on standards such as the WirelessHART and ISA100.11a in factory control systems. However, process control systems vary greatly and have diverse wireless networking requirements in different applications. These requirements include deterministic transmissions in the shared wireless bandwidth, low-cost operation, long-term durability, and high reliability in the harsh radio propagation environment. It is an open question whether a generic wireless technology would meet the requirements of industrial process control. In this paper, we propose a novel simulation framework for performance evaluation of wireless networks in factory and process automation systems. We select a typical process control plant model, specifically the Tennessee Eastman Challenge (TE) Model, and define the interfaces between the process simulator and the wireless network simulator. We develop a model of the protocol stack of the WirelessHART specification in the OMNET++ simulation engine as a typical industrial wireless network. We present simulation results that validate the prospect of using WirelessHART in the TE plant, and we evaluate the impact of various wireless network configurations on the plant operation. Given its modular design, the proposed simulation framework can be easily used to evaluate the performance of other industrial wireless networks in conjunction with a variety of process control systems.

TI Los Angeles megacity: a high-resolution land-atmosphere modelling system for urban CO2 emissions SO ATMOSPHERIC CHEMISTRY AND PHYSICS LA English DT Article ID FOSSIL-FUEL CO2; CANOPY MODEL; ERROR CHARACTERIZATION; POLLUTANT TRANSPORT; CARBON-DIOXIDE; HEAT-ISLAND; WRF-VPRM; CALIFORNIA; SCALE; SIMULATIONS AB Megacities are major sources of anthropogenic fossil fuel CO2 (FFCO2) emissions. The spatial extents of these large urban systems cover areas of 10 000 km(2) or more with complex topography and changing landscapes. We present a high-resolution land-atmosphere modelling system for urban CO2 emissions over the Los Angeles (LA) megacity area. The Weather Research and Forecasting (WRF)Chem model was coupled to a very high-resolution FFCO2 emission product, Hestia-LA, to simulate atmospheric CO2 concentrations across the LA megacity at spatial resolutions as fine as similar to 1 km. We evaluated multiple WRF configurations, selecting one that minimized errors in wind speed, wind direction, and boundary layer height as evaluated by its performance against meteorological data collected during the CalNex-LA campaign (May-June 2010). Our results show no significant difference between moderate-resolution (4 km) and high-resolution (1.3 km) simulations when evaluated against surface meteorological data, but the highresolution configurations better resolved planetary boundary layer heights and vertical gradients in the horizontal mean winds. We coupled our WRF configuration with the Vul-can 2.2 (10 km resolution) and Hestia-LA (1.3 km resolution) fossil fuel CO2 emission products to evaluate the impact of the spatial resolution of the CO2 emission products and the meteorological transport model on the representation of spatiotemporal variability in simulated atmospheric CO2 concentrations. We find that high spatial resolution in the fossil fuel CO2 emissions is more important than in the atmospheric model to capture CO2 concentration variability across the LA megacity. Finally, we present a novel approach that employs simultaneous correlations of the simulated atmospheric CO2 fields to qualitatively evaluate the greenhouse gas measurement network over the LA megacity. Spatial correlations in the atmospheric CO2 fields reflect the coverage of individual measurement sites when a statistically significant number of sites observe emissions from a specific source or location. We conclude that elevated atmospheric CO2 concentrations over the LA megacity are composed of multiple fine-scale plumes rather than a single homogenous urban dome. Furthermore, we conclude that FFCO2 emissions monitoring in the LA megacity requires FFCO2 emissions modelling with similar to 1 km resolution because coarser-resolution emissions modelling tends to overestimate the observational constraints on the emissions estimates.

TI A multi-model intercomparison of halogenated very short-lived substances (TransCom-VSLS): linking oceanic emissions and tropospheric transport for a reconciled estimate of the stratospheric source gas injection of bromine SO ATMOSPHERIC CHEMISTRY AND PHYSICS LA English DT Article ID TROPICAL TROPOPAUSE LAYER; GENERAL-CIRCULATION MODEL; ASIAN MONSOON TRANSPORT; BOUNDARY-LAYER; TRACER TRANSPORT; DEEP CONVECTION; CLIMATE MODEL; WEST PACIFIC; ATMOSPHERIC TRANSPORT; CUMULUS CONVECTION AB The first concerted multi-model intercomparison of halogenated very short-lived substances (VSLS) has been performed, within the framework of the ongoing Atmospheric Tracer Transport Model Intercomparison Project (TransCom). Eleven global models or model variants participated (nine chemical transport models and two chemistry-climate models) by simulating the major natural bromine VSLS, bromoform (CHBr3) and dibromomethane (CH2Br2), over a 20-year period (1993-2012). Except for three model simulations, all others were driven offline by (or nudged to) reanalysed meteorology. The overarching goal of TransCom-VSLS was to provide a reconciled model estimate of the stratospheric source gas injection (SGI) of bromine from these gases, to constrain the current measurement-derived range, and to investigate inter-model differences due to emissions and transport processes. Models ran with standardised idealised chemistry, to isolate differences due to transport, and we investigated the sensitivity of results to a range of VSLS emission inventories. Models were tested in their ability to reproduce the observed seasonal and spatial distribution of VSLS at the surface, using measurements from NOAA's long-term global monitoring network, and in the tropical troposphere, using recent aircraft measurements including high-altitude observations from the NASA Global Hawk platform. The models generally capture the observed seasonal cycle of surface CHBr3 and CH2Br2 well, with a strong modelmeasurement correlation (r >= 0.7) at most sites. In a given model, the absolute model-measurement agreement at the surface is highly sensitive to the choice of emissions. Large inter-model differences are apparent when using the same emission inventory, highlighting the challenges faced in evaluating such inventories at the global scale. Across the ensemble, most consistency is found within the tropics where most of the models (8 out of 11) achieve best agreement to surface CHBr3 observations using the lowest of the three CHBr3 emission inventories tested (similarly, 8 out of 11 models for CH2Br2). In general, the models reproduce observations of CHBr3 and CH2Br2 obtained in the tropical tropopause layer (TTL) at various locations throughout the Pacific well. Zonal variability in VSLS loading in the TTL is generally consistent among models, with CHBr3 (and to a lesser extent CH2Br2) most elevated over the tropical western Pacific during boreal winter. The models also indicate the Asian monsoon during boreal summer to be an important pathway for VSLS reaching the stratosphere, though the strength of this signal varies considerably among models. We derive an ensemble climatological mean estimate of the stratospheric bromine SGI from CHBr3 and CH2Br2 of 2.0 (1.2-2.5) ppt, similar to 57% larger than the best estimate from the most recent World Meteorological Organization (WMO) Ozone Assessment Report. We find no evidence for a long-term, transport-driven trend in the stratospheric SGI of bromine over the simulation period. The transport-driven interannual variability in the annual mean bromine SGI is of the order of +/- 5 %, with SGI exhibiting a strong positive correlation with the El Nino-Southern Oscillation (ENSO) in the eastern Pacific. Overall, our results do not show systematic differences between models specific to the choice of reanalysis meteorology, rather clear differences are seen related to differences in the implementation of transport processes in the models.

TI Speciation of OH reactivity above the canopy of an isoprene-dominated forest SO ATMOSPHERIC CHEMISTRY AND PHYSICS LA English DT Article ID VOLATILE ORGANIC-COMPOUNDS; SOUTHEASTERN UNITED-STATES; TROPOSPHERIC DEGRADATION; MASS-SPECTROMETRY; AEROSOL FORMATION; PHOTOOXIDATION; MODEL; FIELD; PART; HYDROPEROXIDES AB Measurements of OH reactivity, the inverse lifetime of the OH radical, can provide a top-down estimate of the total amount of reactive carbon in an air mass. Using a comprehensive measurement suite, we examine the measured and modeled OH reactivity above an isoprene-dominated forest in the southeast United States during the 2013 Southern Oxidant and Aerosol Study (SOAS) field campaign. Measured and modeled species account for the vast majority of average daytime reactivity (80-95 %) and a smaller portion of nighttime and early morning reactivity (68-80 %). The largest contribution to total reactivity consistently comes from primary biogenic emissions, with isoprene contributing similar to 60% in the afternoon, and similar to 30-40% at night and monoterpenes contributing similar to 15-25% at night. By comparing total reactivity to the reactivity stemming from isoprene alone, we find that similar to 20% of the discrepancy is temporally related to isoprene reactivity, and an additional constant similar to 1 s(-1) offset accounts for the remaining portion. The model typically overestimates measured OVOC concentrations, indicating that unmeasured oxidation products are unlikely to influence measured OH reactivity. Instead, we suggest that unmeasured primary emissions may influence the OH reactivity at this site. C1 [Kaiser, J.; Skog, K. M.] Univ Wisconsin, Dept Chem, 1101 Univ Ave, Madison, WI 53706 USA.

This is achieved by synchronizing time series at single grid pixels according to the first day of rain after a dry spell of prescribed duration. The full track of the temporal evolution several weeks before and after a rain pulse is retained with daily resolution. These are needed for a sophisticated background correction, which accounts for seasonal variations in the time series and allows for improved quantification of rain-induced soil emissions. The method is applied globally and provides constraints on pulsed soil emissions of NOx in regions where the NOx budget is seasonally dominated by soil emissions. We find strong peaks of enhanced NO2 vertical column densities (VCDs) induced by the first intense precipitation after prolonged droughts in many semi-arid regions of the world, in particular in the Sahel. Detailed investigations show that the rain-induced NO2 pulse detected by the OMI (Ozone Monitoring Instrument), GOME-2 and SCIAMACHY satellite instruments could not be explained by other sources, such as biomass burning or lightning, or by retrieval artefacts (e.g. due to clouds). For the Sahel region, absolute enhancements of the NO2 VCDs on the first day of rain based on OMI measurements 2007-2010 are on average 4 x 10(14) molec cm(-2) and exceed 1 x 10(15) molec cm(-2) for individual grid cells. Assuming a NOx lifetime of 4 h, this corresponds to soil NOx emissions in the range of 6 up to 65 ng N m(-2) s(-1), which is in good agreement with literature values. Apart from the clear first-day peak, NO2 VCDs are moderately enhanced (2 x 10(14) molec cm(-2)) compared to the background over the following 2 weeks, suggesting potential further emissions during that period of about 3.3 ng N m(-2) s(-1). The pulsed emissions contribute about 21-44% to total soil NOx emissions over the Sahel.

In addition to strong resonant absorption centered around 1550 nm, the material provides strong sub-bandgap photoconductivity and >> mu W average power levels when fabricated into an efficient (square spiral) THz antenna and driven by a 1550-nm ultrafast fiber laser. Photo-Hall measurements prove that the predominant photocarrier is the electron and the linearity of the 1550-nm photocurrent (with laser power) suggests that the photoconductivity is "extrinsic", not other possible mechanisms, such as two-photon absorption. These results have immediate relevance to the use of GaAs:Er switches as the transmitter in 1550-nm-driven THz imaging systems such as the "impulse imager" that we have successfully used for biomedical imaging applications.

TI Selection and quality assessment of Landsat data for the North American forest dynamics forest history maps of the US SO INTERNATIONAL JOURNAL OF DIGITAL EARTH LA English DT Article DE Landsat; forest cover change; time-series mapping; forest disturbance; North American forest dynamics; nasa earth exchange ID CONTERMINOUS UNITED-STATES; COVER CHANGE; TIME-SERIES; SATELLITE DATA; CLOUD SHADOW; DATA SET; IMAGERY; OPPORTUNITIES; CONTINUITY; MISSION AB Using the NASA Earth Exchange platform, the North American Forest Dynamics ( NAFD) project mapped forest history wall-to-wall, annually for the contiguous US ( 1986-2010) using the Vegetation Change Tracker algorithm. As with any effort to identify real changes in remotely sensed time-series, data gaps, shifts in seasonality, misregistration, inconsistent radiometry and cloud contamination can be sources of error. We discuss the NAFD image selection and processing stream ( NISPS) that was designed to minimize these sources of error. The NISPS image quality assessments highlighted issues with the Landsat archive and metadata including inadequate georegistration, unreliability of the pre-2009 L5 cloud cover assessments algorithm, missing growing-season imagery and paucity of clear views. Assessment maps of Landsat 5-7 image quantities and qualities are presented that offer novel perspectives on the growing-season archive considered for this study. Over 150,000+ Landsat images were considered for the NAFD project. Optimally, one high quality cloud-free image in each year or a total of 12,152 images would be used. However, to accommodate data gaps and cloud/ shadow contamination 23,338 images were needed. In 220 specific path-row image years no acceptable images were found resulting in data gaps in the annual national map products.

Fish meal in the control diet (CD) was replaced in the experimental diets by low molecular weight hydrolysate (LMWH) protein derived from Pacific whiting (Merluccius productus) processing waste, or by Atlantic salmon (Salmo salar) processing trim (ST), which was incorporated into the feed with an experimental heated ball mill. The feeding trial was conducted in an indoor recirculating seawater system and each feed was randomly assigned to triplicate groups of 50 fish (average initial body weight of 57.5 g). The results showed that compared to the control diet, the diets containing LMWH or ST significantly increased feed consumption and fish weight gain. The ST group showed a significantly higher weight gain than the LMWH group. The ST feed, but not the LMWH feed, had a significantly lower feed conversion ratio than the CD feed. The ST feed increased lipid retention efficiency and lipid content in whole body tissue. These results demonstrate that salmon fish trim waste and enzyme hydrolyzed whiting trim in high plant protein diets can increase the performance in sablefish.

TI Evaluating the Efficacy of Trawl Exclusion Zones by Estimating Local Atka Mackerel Abundance and Movement Patterns in the Central and Eastern Aleutian Islands SO MARINE AND COASTAL FISHERIES LA English DT Article ID STELLER SEA LIONS; PLEUROGRAMMUS-MONOPTERYGIUS; RESPECT; HABITAT AB Atka Mackerel Pleurogrammus monopterygius is the most abundant commercially exploited groundfish in the Aleutian Islands, Alaska. It is also the predominant prey of the endangered Steller sea lion Eumetopias jubatus in the Aleutians Islands range. In 1992, trawl exclusion zones (TEZs) that ranged from 10 to 20 nautical miles were established around rookeries to protect Steller sea lion prey abundance. This study examined the efficacy of the TEZs by estimating the movement and local abundance (10-20 nautical miles) of Atka Mackerel inside and outside of these zones using an integrated tagging model that incorporated independent data for tagging survival, recruitment, and tag reporting rates. Atka Mackerel were tagged, released, and recovered from 2000 to 2006 at four Aleutian Island locales, from both inside and outside of the TEZs. Atka Mackerel local abundance and their movement patterns across these harvest boundaries were estimated for all the study areas inside and outside the TEZs, and local exploitation rate by the fishery was calculated for each area open to fishing outside the TEZ boundary. In areas with high Atka Mackerel abundance and little movement from inside to outside the protection zones (e.g., Seguam Pass and Kiska Island), the TEZs were expected to work well to preserve the prey field for Steller sea lions. In areas of low Atka Mackerel abundance and frequent movement from the inside to the outside of the protection zone (e.g., Amchitka Island), the TEZs were expected to be less effective. Our study indicated that TEZs can be effective for preserving prey fields of Atka Mackerel for Steller sea lions, but each study area needs to be carefully evaluated in order to understand area-specific variations in abundance and movement patterns.

TI Using Movements and Habitat Utilization as a Functional Metric of Restoration for Estuarine Juvenile Fish Habitat SO MARINE AND COASTAL FISHERIES LA English DT Article ID HALIBUT PARALICHTHYS-CALIFORNICUS; SOUTHERN CALIFORNIA; SITE FIDELITY; ACOUSTIC TELEMETRY; DYNAMICS; PATTERNS; CONNECTIVITY; MIGRATION; ABUNDANCE; ENGLAND AB Resource managers use habitat restoration to offset estuarine habitat loss; however, there is limited information about how functionally successful restorations have been, particularly with respect to their use by mobile marine predators. Restoration monitoring efforts typically use point-of-capture metrics to assess fish community recovery and habitat use, but this provides little insight into how fish habitat use changes through time. Using translocation experiments, we integrated the movements of California Halibut Paralichthys californicus, a conservation target species, into a point-of-capture monitoring program in a restored tidal creek estuary. Large halibut (>25 cm) were captured more frequently in the main stream channel, while small ones (<25 cm) were typically caught in the innermost marsh creeks. We actively tracked these fish (n = 20; size range = 26.6-60.5 cm TL) acoustically to identify their preferred habitats and challenged these habitat associations by means of translocations to a different habitats. Large fish tended to have small localized convex hull activity spaces, remaining in areas with high water flow and sandy substratum near eelgrass Zostera marina beds. Individuals that were translocated to marshes returned to the channel and exhibited movements over long distances from their initial locations to their last tracked positions; however, fish that were translocated from marshes to the channel remained in channel habitat and moved smaller distances between their first and last tracked points. Large halibut likely selected the channel because higher water flow would lead to higher concentrations of prey. Small halibut used marshes more frequently, likely because marshes have temperatures thought to maximize growth rates. Our study can serve as a proof of concept that linking point-of-capture and tracking data provides valuable information for habitat restoration, including the fact that California Halibut utilize estuaries in a size-segregated manner based on environmental conditions. This suggests that tidal creek estuaries with a variety of channel types and morphologies-like our study site-are well-suited to support this species.

TI Feasibility of Tagging Walleye Pollock Captured with Hook and Line using External Tags SO MARINE AND COASTAL FISHERIES LA English DT Article AB We evaluated methods of minimizing mechanical injury to Walleye Pollock Gadus chalcogrammus when tagging them with external identification tags. Walleye Pollock (20-62 cm FL) were captured with hook and line near Auke Bay, Southeast Alaska, and were tagged with either T-bar anchor tags or lock-on tags, which were anticipated to be used for tagging studies in the Gulf of Alaska and Bering Sea. The tested handling procedures included transferring the tagged fish between live tanks either by using a dip net (dipnetted group) or with wet, bare hands (non-dipnetted group). Sixty percent of the dipnetted fish (63 of 105) died, whereas 12% of the non-dipnetted fish (17 of 138) died. Overall, 50% of the deaths occurred within 7 d after capture, and 89% of the deaths occurred within 10 d after capture. Of the dipnetted fish that died, 68% (n = 43) died from dermal infection due to scale loss, whereas 30% of the non-dipnetted fish mortalities were from dermal infection. Additionally, injuries that were recorded as potential mortality factors included fin loss, torn jaws, internal dysfunction, and unknown. All of the fish that received lock-on tags and 93% of the fish that were anchor-tagged developed an infection at the point of tag insertion. Tag retention rates were 99.5% for lock-on tags and 93.7% for anchor tags, and tag type did not affect survival. Use of hook-and-line capture is an effective method for reducing mechanical injury and mortality in Walleye Pollock. Recommended procedures for capturing and tagging Walleye Pollock include the use of hook and line and the use of wet, bare hands (or a similar low-abrasion approach) when handling the fish.
