The H atoms are generated by laser photolysis of HI and have well-defined kinetic energies in the range of 1-3 eV. For an incident H atom average kinetic energy of [E-H] = 1.1 eV, the HD product kinetic energy distribution has a mean value of [E-HD] = 1.2-1.3 eV and extends up to the nominal available-energy limit, providing dynamical evidence for a direct Eley-Rideal mechanism for this abstraction reaction. For [EH] = 1.5 and 3.2 eV, the HD product kinetic energy distribution broadens relative to that for [E-H] = 1.1 eV while [E-HD] remains unchanged, suggesting that energy loss to the substrate becomes more significant and the reaction becomes less Eley-Rideal-like for these higher energies. The results are compared with recent classical trajectory calculations. (C) 1998 American Institute of Physics. C1 Natl Inst Stand & Technol, Surface & Microanal Sci Div, Gaithersburg, MD 20899 USA.

It has been argued that such structures could explain the polarization properties of some jets and contribute to their lateral confinement through magnetic tension forces. A concentric toroidal field geometry is also central to the Rees-Gunn model for the Crab Nebula, the archetypal plerion, and leads to the deduction that the Crab pulsar's wind must have a weak magnetic field. Yet this kind of equilibrium between magnetic and gas pressure forces, the "equilibrium Z-pinch" of the controlled fusion literature, is well known to be susceptible to disruptive localized instabilities, even when the magnetic field is weak and/or boundary conditions (e.g., a dense external medium) slow or suppress global modes. Thus, the magnetic field structures imputed to the interiors of jets and plerions are unlikely to persist for very long To determine the growth rates of Z-pinch instabilities under astrophysical conditions, I derive a dispersion relation that is valid for the relativistic fluids of which jets and plerions may be composed, in the ideal magnetohydrodynamics (MHD) limit. The dominant instabilities are kink (m = 1) and pinch (m = 0) modes. The former generally dominate, destroying the concentric field structure and probably driving the system toward a more chaotic state in which the mean field strength is independent of radius (and in which resistive dissipation of the field may be enhanced). I estimate the timescales over which the field structure is likely to be rearranged and relate these to distances along relativistic jets and radii from the central pulsar in a plerion. I conclude that the central tenet of the Rees-Gunn model for the Crab Nebula, the existence of a concentric toroidal held well outside the pulsar wind's termination shock, is physically unrealistic. With this assumption gone, there is no dynamical reason to conclude that the magnetic energy flux carried by the pulsar wind is much weaker than the kinetic energy flux. Abandoning the principal conclusion of Rees & Gunn would resolve a long-standing puzzle in pulsar wind theory. C1 Univ Colorado, Dept Astrophys & Planetary Sci, JILA, Boulder, CO 80309 USA.

Over the same period, air samples were collected in flasks for analysis of CO and other trace gases as part of the NOAA-CMDL cooperative air sampling network. We compared the continuous GFC measurements with the National Oceanic and Atmospheric Administration Climate Monitoring and Diagnostics Laboratory (NOAA-CMDL) flask data. Over this 1-year period, CO mixing ratios varied between 60 and 250 parts per billion by volume (ppbv). Within this range, the comparison between the two measurements is quite good, with an overall R-2 of 0.953 and an average difference of 3.1%. A seasonal cycle is apparent in the CO data, with a springtime maximum and a summer minimum. Synoptic influences on the data include transport from the lower-latitude Pacific, bringing air with very low CO mixing ratios to Shemya, and, occasionally, transport from industrial areas in east Asia, including northern China, Japan, and eastern Russia. A scatterplot of CO versus O-3 using all the data shows essentially no relationship at this remote site. This result implies that the primary sources and sinks for these trace gases are different at this location, However, during a few 12- to 48-hour periods in fall and late spring, enhancements in CO or in both CO and O-3 were observed. During these periods, isentropic back trajectories indicate transport from the west and southwest. However, the trajectories are often difficult to interpret due to looping and are of short duration due to impact at the surface. These complexities are associated with the presence of cyclonic systems in the region. The local meteorological data suggest that the enhanced concentrations occurred around the time when these cyclonic systems passed near the sampling site. Synoptic surface pressure maps indicate that these cyclonic systems formed or crossed industrial regions in east Asia and passed near Shemya on their way to the Bering Sea. This process suggests a role for transport of anthropogenic pollutants by cyclonic systems moving northward along the western edge of the Pacific Ocean.

Halon emissions persist because of a lack of suitable substitutes for critical uses as fire extinguishants. As of January 1, 1997, halons H-1301 (CBrF3), H-1211 (CBrClF2), and H-2402 (CBr2F4) were present in the troposphere at 2.3+/-0.1, 3.5+/-0.1, and 0.45+/-0.03 pmol mol(-1). During 1995-1996 the tropospheric mole fraction of H-1301 increased at 0.044+/-0.011 pmol mol(-1) yr(-1), while that for H-1211 grew at 0.16+/-0.016 pmol mol(-1) yr(-1). These increases are significant and of concern because of the efficiency of bromine in depleting stratospheric ozone and because of the long atmospheric lifetimes of these gases. Given the current atmospheric record and the reported amount of halon produced before the ban on production, emission of H-1301 at the 1995-1996 rate could continue for another 40 years, but H-1211 would be depleted in 8-12 years. Exemptions to the ban on production may extend these periods. Tropospheric H-2402 is increasing at 9+/-1 fmol mol(-1) yr(-1), but historical data on its production and use are lacking.

Stratospheric air was analyzed for these gases and others with a new gas chromatograph, flown aboard a National Aeronautics and Space Administration ER-2 aircraft as part of the Airborne Southern Hemisphere Ozone Experiment/Measurements for Assessing the Effects of Stratospheric Aircraft mission conducted in 1994. The mixing ratio of SF6, with its nearly linear increase in the troposphere, was used to estimate the mean age of stratospheric air parcels along the EK-2 flight path. Measurements of H-1211 and mean age estimates were then combined with simultaneous measurements of CFC-11 (CCl3F), measurements of brominated compounds in stratospheric whole air samples, and records of tropospheric organic bromine mixing ratios to calculate the dry mixing ratio of total bromine in the lower stratosphere and its partitioning between organic and inorganic forms. We estimate that the organic bromine-containing species were almost completely photolyzed to inorganic species in the oldest air parcels sampled. Our results for inorganic bromine are consistent with those obtained from a photochemical, steady state model for stratospheric air parcels with CFC-11 mixing ratios greater than 150 ppt. For stratospheric air parcels with CFC-11 mixing ratios less than 50 ppt (mean age greater than or equal to 5 years) we calculate inorganic bromine mixing ratios that are approximately 20% less than the photochemical, steady state model. There is a 20% reduction in calculated ozone loss resulting from bromine chemistry in old air relative to some previous estimates as a result of the lower bromine levels.

Significant evidence was found supporting the notion that the OH/DMS addition reaction is a major source of dimethyl sulfoxide (DMSO), Methane sulfonic acid (MSA(g)) levels were also found to be consistent with an OH/DMS addition mechanism involving the sequential oxidation of the products DMSO and methane sulfinic acid (MSIA). Evidence supporting the hypothesis that the OH/DMS addition reaction, as well as follow-on reactions involving OH/DMSO, are a major source of SO2 was significant, but not conclusive. No evidence could be found supporting the notion that reactive intermediates (i.e., SO3) other than SO2 were an important source of H2SO4. Quite clearly, one of the major findings of SCATE was the recognition that a large fraction of the Antarctic oxidative cycle for DMS (near Palmer Station) took place above the boundary layer (BL) in what we have labeled here as the atmospheric buffer layer (BuL). Although still speculative in places, the overall picture emerging from the SCATE field/modeling results is one involving major coupling between chemistry and dynamics in the Antarctic. At Palmer the evidence points to frequent episodes of rapid vertical transport from a very shallow marine BL into the overlying BuL. Due to the combination of a long photochemical lifetime for DMS and the frequency of shallow convective events, a large fraction of ocean released DMS is transported into the BuL while still in its unoxidized state. There, in the presence of elevated OH and low aerosol scavenging, high levels of oxidized sulfur accumulate. Parcels of this BuL air are then episodically entrained back into the BL, thereby providing a controlling influence on BL SO2, DMSO, and DMSO2. Additionally, because SO? and DMSO are major precursors to H2SO4 and MSA, BuL chemistry, in conjunction with vertical transport, also act to control BL levels of the latter species. Although many uncertainties remain in our understanding of Antarctic DMS chemistry, the above picture already suggests that previous chemical interpretations of Antarctic field data may need to be altered.

Comparison of six reversed-phase columns indicates that deactivated stationary phases, which utilize ultrapure silica and maximize coverage of the silica support, provide significantly improved separation and chromatographic efficiencies for catechin analyses using LC, compared to conventional monomeric or polymeric C-18 columns. Evaluation of elution conditions used for the separations reveals that the presence of acid in the mobile phase (0.05% trifluoroacetic acid) is essential for both the complete resolution of the catechins present in tea and the efficient chromatography of these compounds. The efficacy of one of the developed systems was demonstrated by the quantitative measurement of the six biologically active catechins in aqueous infusions of green tea (Camellia sinensis). Overall precision values for the analyses were within the range 0.3-1% (relative standard deviation).

Dichloro-, tetrachloro-, and decachlorobiphenyl congeners were solubilized in water using a commercially available non-ionic surfacta nt, Triton X-100, and subsequently irradiated by a Co-60 gamma-source. Rates and extent of dechlorination were determined at different surfactant concentrations, and intermediate species and byproducts were quantified. Pulse radiolysis was used to measure rates of reaction between PCBs and the solvated electron as well as rates of electron scavenging by the surfactant. Experiments were also conducted in organic solvents, and these results have been compared to those observed in the aqueous surfactant solutions. Each PCB congener was fully dechlorinated by ionizing radiation in the micellar systems. Initial chloride yields were directly proportional to the level of chlorination of the PCB congeners. Scavenging of the aqueous electron by the surfactant was significant, and PCB degradation efficiency improved markedly at lower surfactant concentrations. PCB transformation occurred primarily through reductive dechlorination, forming lower chlorinated PCBs and biphenyl. Rates of PCB degradation were substantially higher in aqueous surfactant solutions than in diethyl ether and petroleum ether. This suggests that solubilizing PCBs in water using a surfactant prior to irradiation may provide a considerable improvement in contaminant degradation efficiency in comparison to using an organic solvent or irradiating PCBs directly in oil.

The crossover expressions for the thermal conductivity, the binary diffusion coefficient, the thermal diffusion coefficient, and the thermal diffusion ratio incorporate scaling laws near the critical point and are transformed to regular background values far away from the critical point. In the limits of pure components, the crossover expression for the thermal conductivity of binary mixtures is transformed to the crossover expression for the thermal conductivity of pure fluids. For the calculation of the regular backgrounds transport properties of pure fluids, we use dense fluid contributions obtained from independently fitting pure fluid data and a dilute gas contribution from Chapman-Enskog theory. A comparison is made with thermal conductivity data for pure carbon dioxide, methane, ethane, and carbon dioxide + ethane and methane + ethane mixtures. (C) 1998 Elsevier Science B.V.

From two stations at high northern hemisphere (NH) latitudes there has been a significant decline in ozone amounts throughout the troposphere since the early 1980s. At midlatitudes of the NH where data are the most abundant, on the other hand, important regional differences prevail. The two stations in the eastern United States show that changes in ozone concentrations since the early 1970s have been relatively small. At the two sites in Europe, however, ozone amounts increased rapidly into the mid-1980s, but have increased less rapidly (or in some places not at all) since then. Increases at the Japanese ozonesonde station have been largest in the lower troposphere, but have slowed in the recent decade. The tropics are sparsely sampled but do not show significant changes. Small increases are suggested at southern hemisphere (SH) midlatitudes by the two surface data records. In Antarctica large declines in the ozone concentration are noted in the South Pole data, and like those at high latitudes of the NH, seem to parallel the large decreases in the stratosphere.

A portion of the observed O(D-1) quantum yields at wavelengths greater than 310 nm is attributed to a spin-forbidden channel and the variation of quantum yield with temperature is ascribed to photodissociation of vibrationally (or rotationally) excited ozone. Our results yield atmospheric O(D-1) production rates larger than those obtained from current recommendations, especially at high solar zenith angles, low temperatures, and large overhead ozone columns.

A modified gaseous electronics conference rf reference cell with an inductively coupled source is used to produce the discharges, with pressures ranging from 1.3 Pa to 5.3 Pa and applied powers from 100 W to 300 W. Neutrals are sampled from the side of the discharge, and the degree of dissociation is determined mass spectrometrically by comparison of the intensities of the parent ion peaks with the plasma power on and off. Measured dissociation levels of O-2 in Ar:O-2 mixtures ranged from 0.02 (i.e., 2% of the oxygen molecules were dissociated) to 0.08 (8%), while dissociation levels for Ar:SF6 mixtures ranged from 0.92 to 0.98, depending upon plasma conditions. The degree of dissociation of Cl-2 in Ar:Cl-2 mixtures ranged from near 0.07 to 0.19, while dissociation levels of N-2 in Ar:N-2 mixtures were less than 2% for all plasma conditions studied.

Each spectrum is composed of a single broad feature that shifts toward higher electron binding energy as the number of solvent molecules increases. Analysis of OH-(N2O) spectra at ion temperatures of 200 and 300 K shows that there is significant intensity in the 0(0)(0) transition, and that transitions to the dissociative region of the OH + N2O potential energy surface are also accessed. The electron affinity of OH(N2O) is estimated to be 2.14+/-0.02 eV, from which the OH-N2O bond dissociation energy is calculated as 0.39 eV. The photoelectron spectra of OH-(N2O)(n>1) are accurately modeled as the convolution of the OH-(N2O) spectrum with the OH-(N2O)(n-1). The anion vertical detachment energies and the adiabatic electron affinities for OH(N2O)(n=2-5) are obtained and the thresholds for stepwise dissociation of N2O are located, indicating that photodetachment accesses multiple dissociation channels.

The model was spun up from climatological initial conditions and has been integrated for decades representing 1930 to the present. Climatological monthly mean winds were imposed during the spin-up and first 50 years of the integration, From 1980, monthly mean European Centre for Medium-Range Weather Forecasts (ECMWF) wind stress fields were used. We compare model results to cruise data and to long-term mean observations and find good qualitative agreement in most areas. Overall, the model agrees reasonably well in regions where measurable CFCs have. been observed, and the large-scale model ventilation pathways appear realistic. One of the most conspicuous shortcomings is the small volume of Antarctic Intermediate Water in the model results. This leads to errors in the general water mass structure and in CFC concentrations in the model in other regions. Notable CFC differences are found in regions where deep water masses are formed and in the upper subtropical gyre regions in which the Kuroshio extension exists. The model oceanic CFC sink represents <1% of all CFCs produced since 1930 and is small relative to the stratospheric sink for these compounds. C1 Natl Ctr Atmospher Res, Boulder, CO 80307 USA.

Film thickness was measured using x-ray reflectivity, which is a nondestructive technique offering angstrom resolution in the measurements of thin film or multilayer thickness. The effect of several variables on the absorption of moisture were monitored in polyimide films adhered to polished silicon substrates, including total dry film thickness, exposure time, and the contribution of a coupling agent. The percentage increase in film thickness due to moisture uptake is found to be a weak function of dry film thickness, decreasing as dry film thickness increases, and to be somewhat affected by the use of an interfacial coupling agent. The observed behavior points to the polymer/substrate interface as a strong factor controlling the absorption of moisture in the polyimide/silicon system, and is believed to reflect the presence of a highly moisture-saturated interfacial layer. A bilayer model is proposed, and the feasibility of using this model to describe the observed behavior is considered. (C) 1998 John Wiley & Sons, Inc.

Phase-separation measurements are made at a constant temperature difference from the critical temperature, leading to a bicontinuous spinodal decomposition pattern for near-critical blend compositions and to "mounds" and "holes" for PVME-rich and dPS-rich off-critical mixtures, respectively. Reverse temperature jumps of the phase-separated blend films into the one-phase region result in dissolution of the undulating surface patterns, confirming the phase-separation origin of the him patterns.

This study has demonstrated that this technique is capable of measuring the thickness change of 40 nm thick films with a CTE in the 10(-5)/degrees C range. The CTE of ultra-thin hydrogen silsesquioxane films was found to be about 40 ppm/degrees C from 20 to 175 degrees C. After-taking the substrate constraint into consideration, the calculated CTE of the films in their unconstrained condition was about 20 ppm/degrees C. In addition, the density of the films was found to be smaller than that of silica and was non-uniform along the thickness direction with a low density region adjacent to the hydrogen silsesquioxane/silicon interface.

(1996) Nucleic Acids Res. 24, 3307-3312]. The functional analysis of this eukaryotic enzyme indicated that it is a homologue of E. call Nth protein. The gene has been subcloned and the protein (Nth-Spo) purified to apparent homogeneity. We investigated the substrate specificity of this eukaryotic enzyme for modified bases in oxidatively damaged DNA, using the technique of gas chromatography/isotope-dilution mass spectrometry (GC/IDMS). DNA substrates containing up to 17 types of modified bases were prepared by gamma-irradiation or by treatment with. H2O2 in the presence of Fe(III)-EDTA or Cu(II). The results revealed an efficient excision of five pyrimidine-derived lesions, 5-hydroxycytosine, thymine glycol, 5-hydroxy-6-hydrothymine: 5,6-dihydroxycytosine, and 5-hydroxyuracil. None of the other pyrimidine or purine lesions was excised. Excision was measured as a function of enzyme concentration, time, substrate concentration, and temperature. Kinetic constants were determined. Although some DNA base lesions removed by Nth-Spo protein were similar to those previously described for E. coti Nth protein, differences between substrate specificities of these two enzymes were noted.

With the exception of the CBS-4 and BAC-MP4 procedures, the negative errors in the calculated enthalpies were observed to be linearly dependent upon the number of CF bonds in the molecule. Application of a bond additivity correction (BAG) parameter, Delta(C-F), derived in an earlier investigation of fluoro- and chlorofluoromethanes removed some although not all of the systematic deviations. Introduction of a heavy atom interaction parameter, representing the effect of an attached carbon on the C-F bond error, yielded corrected enthalpies which agree with experiment to within the reported uncertainties. The BAC-MP4 method, which has already been parameterized with generalized BACs, yields calculated enthalpies which average approximately 10 kJ mol(-1) below the experimental values of Delta(f)H degrees in the fluoroethanes.

We describe several systematic effects affecting this calibration procedure, The second method used a shift of the Rb Zeeman resonance frequency due to the polarization of He-3. Implementation and calibration of this technique are discussed in detail.

The observations include a long-duration, moderate-resolution spectrum of the coronal Fe XXI lambda 1354 line and both moderate-and high-resolution spectra of the He II lambda 1640 multiplet. Our objective in observing the Fe XXI line formed at T = 1 x 10(7) K is to determine for the first time the line shape parameters and the contribution of each star's corona. This is feasible because the GHRS can resolve the 53 km s(-1) radial velocity separation of the stars. Our analysis led to four surprising results: (1) The contribution of the slowly rotating G8 III star to the total Fe XXI lambda 1354 flux is similar to that of the more active rapidly rotating G1 III star, in contrast to other UV lines formed at lower temperatures. (2) The centroid velocities of the Fe XXI lines from both stars are near their respective photospheric radial velocities. Thus, there is no evidence for downflows or winds, and the hot coronal plasma must be confined, presumably by strong, closed magnetic fields. This is the first direct kinematic evidence for magnetic confinement in the corona of a giant star. (3) The line widths are thermal, indicating very low turbulence (xi < 23 km s(-1)) compared with the 54 km s(-1) thermal speed. (4) Our analysis of Extreme-Ultraviolet Explorer (EUVE) spectra that include four Fe XXI lines shows that the volume emission measures of these lines are about a factor of 3 smaller than for the lambda 1354 line, which was observed several months after the closest EUVE observation. We consider possible explanations for this discrepancy and conclude that variability of the high-temperature coronal emission is the most likely explanation. We observed the He II lambda 1640 line twice with a time separation of 7 months, corresponding to about 2 orbital periods. The profiles are nearly identical, except for a large difference in flux near the expected radial velocity of the G8 III star. We believe that the broad He II emission produced by the G1 star is formed mostly by collisional excitation in its. transition region, while the emission from the G8 star is produced predominantly by a photoionization/recombination process driven by EUV radiation from the G8 star's corona. The He II lambda 1640 flux that we measure from the G8 star is consistent with predictions based on EUVE flux measurements. The decrease in the lambda 1640 emission from the G8 star between the phase 0.73 and 0.78 measurements indicates that its EUV radiation is variable, as is observed by EUVE.

We use these data to measure interstellar properties along these lines of sight and to search for evidence of circumstellar hydrogen walls, which are produced by collisions between the stellar winds and the local interstellar medium (LISM). We were able to model the Ly alpha lines of both stars without hydrogen-wall absorption components, but for 61 Cyg A the fit required a stellar Ly alpha line profile with an improbably deep self-reversal, and for 40 Eri A the fit required a very low deuterium-to-hydrogen ratio that is inconsistent with previous GHRS measurements. Since these problems could be rectified simply by including stellar hydrogen-wall components with reasonable attributes, our preferred fits to the data include these components. We have explored several ways in which the hydrogen-wall properties measured here and in previous work can be used to study stellar winds and the LISM. We argue that the existence of a hydrogen wail around 40 Eri A and a low II I column density along that line of sight imply that either the interstellar density must decrease toward 40 Eri A or the hydrogen ionization fraction (x) must increase. We find that hydrogen-wall temperatures are larger for stars with faster velocities through the LISM. The observed temperature-velocity relation is consistent with the predictions of hydromagnetic shock jump conditions. More precise comparison of the data and the jump conditions suggests crude upper limits for both x and the ratio of magnetic to thermal pressure in the LISM (alpha): x < 0.6 and alpha < 2. The latter upper limit corresponds to a limit on the LISM magnetic field of B < 5 mu G. These results imply that the plasma Mach number of the interstellar wind flowing into the heliosphere is M(A) > 1.3, which indicates that the collision is supersonic and that there should therefore be a bow shock outside the heliopause in the upwind direction. Finally, we estimate stellar wind pressures (P(wind)) from the measured hydrogen-wall column densities. These estimates represent the first empirical measurements of wind properties for late-type main-sequence stars. The wind pressures appear to be correlated with stellar X-ray surface fluxes, F(X), in a manner consistent with the relation P(wind) proportional to F(X)(-1/2), a relation that is also consistent with the variations of P(wind) and F(X) observed during the solar activity cycle. If this relation can in fact be generalized to solar-like stars, as is suggested by our data, then it is possible to estimate stellar wind properties simply by measuring stellar X-rays. One implication of this is that stellar wind pressures and mass-loss rates are then predicted to increase with time, since F(X) is known to decrease with stellar age.

The data allow a direct examination of the processes that produce O-3 in this region of the atmosphere. Comparison of the measured concentrations of OH and HO2 with calculations based on their production from water vapor, ozone, and methane demonstrate that these sources are insufficient to explain the observed radical concentrations in the upper troposphere. The photolysis of carbonyl and peroxide compounds transported to this region from the lower troposphere may provide the source of HOx required to sustain the measured abundances of these radical species. The mechanism by which NO affects the production of O-3 is also illustrated by the measurements. In the upper tropospheric air masses sampled, the production rate for ozone (determined from the measured concentrations of HO2 and NO) is calculated to be about I part per billion by volume each day. This production rate is faster than previously thought and implies that anthropogenic activities that add NO to the upper troposphere, such as biomass burning and aviation, will lead to production of more O-3 than expected.

The enormous size and lack of format standardization that is typical of large model outputs pose challenges to easy data access when collaborators are geographically separated. We present a publicly available Web server that surmounts these barriers and enables a modeler to share his/her results with distant colleagues with minimal effort. Using this server, sharing the latest model results requires little more than copying the datasets into a Web server directory. The server provides on-the-fly visualizations of horizontal and vertical sections, Hofmoller diagrams, and line plots. It provides subsetting of data and downloads formatted subsets in a variety of common file formats. Configuration controls on the server allow the data provider to tailor the services provided to individual users. The server provides a data discovery and access path through the NOAAServer for NOAA collaborators. C1 NOAA, Pacific Marine Environm Lab, Seattle, WA 98115 USA.

The first step consists of selecting optically thick clouds having at least 0.40 of visible reflectance. An empirical screening of non-precipitating cirrus is used. Then, effective radius of cloud particles near their tops is derived from the reflected solar irradiance at 3.9 mu m. The study shows that areas of clouds having at least 15 mu m as effective radius correspond well to rainy areas as delineated by the radar observations. The present algorithm uses the effective radius of cloud tap particles only to separate between rainy and non-rainy pixels. For each pixel defined as rainy, the associated instantaneous rain rate is competed using pre-calibrated probability functions and mean rain rate for groups of 10 K. For each group of temperature, the rain rate is obtained by the product of the probability of rain and mean rain rate within that group of temperature.

Such high resolution imaging techniques as SEMs and scanning probe microscopes can present serious metrology problems in modeling, throughput, and accuracy. Accordingly, photomask metrology must be examined in the larger context of mask, design, specification, manufacture, and application. Critical mask features may not always be measured directly as in the past. Instead, their optical effects can be measured and compared with specifications. Discrepancies indicate needed corrections in mask fabrication process control. In the early days of integrated circuit lithography, an era which might be termed paleolithography the pattern on the photomask was transferred conformally to the wafer. Mask CD were measured directly in a metrology microscope and represented their corresponding wafer CDs. The optical transform from mask to wafer was simply the scalar exposure system reduction ratio. In the present era of neolithography, with wafer CDs near the exposure wavelength, this is no longer the case. The wafer exposure system performs a nonlinear optical transform on the mask pattern to produce an aerial image in the resist. OPC and mask phase shifters are manifestations of the inverse of this transform. The image in the developed resist depends on the mask pattern and the exposure and development parameters in nonlinear ways. These parameter scan be optimized in software, but their effects are equally important in both mask design and mask metrology. A conceptualization of the photomask Life cycle will be presented showing the role of mask metrology in context. This approach can lead to practical solutions of the mask metrology problems in neolithography. C1 Natl Inst Stand & Technol, Gaithersburg, MD 20899 USA.

These tools are based on different operating principles, and have differing cost, throughput, footprint, etc. But how do their potential accuracies differ, and is this important? In this context the effects of tool resolution, the meaning of measurement accuracy and traceability, the role of standards, and how these fit into the measurement model and affect manufacturing profitability are discussed. These considerations can help in choosing the right tool for the measurement task at hand and in evaluating the measurement results. C1 Natl Inst Stand & Technol, Gaithersburg, MD 20899 USA.

The distributions obtained by the two methods are compared to show the strengths of both methods, the high near-surface resolution of the TP method (better than 100 nm) and the nearly constant resolution versus depth of the LIPP method (about 2 mu m). In addition to the expected implanted negative charge at a depth governed by the electron energy, a negative near-surface charge layer was Found close to the metal/FEP interface if the electron beam entered the dielectric through that interface. positive charge layers extending from both surfaces to depths (order 1 mu m) depending on the depth of the negative charges were also observed. This behavior provides new insights in the charging of dielectrics using electron beams. C1 Natl Inst Stand & Technol, Div Polymers, Gaithersburg, MD 20899 USA.

It is determined that the pulse phase distribution is adequately modeled by a normal (Gaussian) distribution. Based on such best-fit normal distributions, estimated mean values of the phase and the standard deviations are given for the individual PD pulse distributions. For the alternating voltage case, the spread of time-of-occurrence distributions of succeeding pulses are universally broader than that of preceding pulses. PD pulse separations are non-uniform in phase. Further, if one assumes the usual sinusoidal waveform, then the voltage separation of PD pulses are also seen to be non-uniform.

Recently, the evaluation of all binding corrections to the Lamb shift of nP states in hydrogenlike systems at low Z up to the order of alpha(7) (n = 2,3,4) has been completed [1, 2]. Using an extrapolation of numerical results, it is possible to obtain an approximate value for higher-order corrections to excited S-states also. Moreover, a calculation is in progress whose ultimate goal is to eliminate any error from low-Z type series expansions or extrapolations of numerical data for high Z. This calculation involves the use of convergence acceleration techniques for certain hypergeometric series [3] and takes advantage of the NIST SGI POWER ONYX and IBM SP/2 supercomputing facilities.

Existing approaches to tolerance analysis and synthesis entail detailed knowledge of geometry of the assemblies and are mostly applicable during advanced stages of design, leading to a less than optimal design process. During the design process of assemblies, both the assembly structure and associated tolerance information evolve continuously and significant gains can be achieved by effectively using this information to influence the design of the assembly. Motivated by this, we identify and explore two goals of research that we believe can expand the scope of tolerancing to the entire design process. The first goal is to advance tolerancing decisions to the earliest possible stages of design. This issue raises the need for effective representation of tolerancing information during early stages of design and for effective assembly modeling. The second goal addresses the appropriate use of industry best practices and efficient computational approaches for tolerance analysis and synthesis. Pursuit of these goals leads to the definition of a multi-level approach that enables tolerancing to be addressed at successive stages of design in an incremental, continuous ongoing fashion. The resulting design process, which we call the Design for Tolerance process, integrates three important domains: (1) design activities at successive stages of design; (2) assembly models that evolve continuously through the design process; and (3) methods and best practices for tolerance analysis and synthesis. We demonstrate major steps of our proposed approach through a simple, yet illustrative, example. C1 Natl Inst Stand & Technol, Gaithersburg, MD 20899 USA.

These tool kits would help engineers be more productive in the process of conceiving, designing, modeling, evaluating, and planning the implementation of manufacturing systems. Although individual tools are available to perform some of these functions, integrated tool kits are not. The lack of common information models and interface standards inhibits the development of interoperable software tools. The Production System Engineering (PSE) project at the National Institute of Standards and Technology (NIST) is working with U.S. industry, academia, and a number of international collaborators to address this problem. One set of interfaces that is required far tool kit integration is between virtual reality (VR) simulations and other manufacturing engineering applications. Virtual manufacturing technology allows engineers to construct a virtual model of the production system and evaluate its performance before the physical system is implemented The project team, working with the Black and Decker Corporation, selected a miter saw as a test case for production system engineering using virtual reality. The miter saw assembly line is an example of one real world production problem that has been used to identify requirements for engineering tool integration. NIST-developed VR simulations presented in this paper include a machine shop. an entire miter saw assembly line, a human assembly operations at a single workbench, and a turning center (lathe) with error modeling. This paper presents our progress in developing techniques, VR simulation models, and tool kit interfaces for production systems engineering.

Regardless of the calibration method used, the antenna to be calibrated should be located where the field varies slowly. We derive the conditions for a slowly varying field near the location of constructive interference as a function of the height of the transmitting antenna and the field geometry. We show experimental data taken by keeping the receiving antenna fixed per the ANSI standard and scanning the transmitting antenna in height. Repeatability of antenna factor data is improved to less than +/-0.3 dB by avoiding nulls in the field. C1 Natl Inst Stand & Technol, Div Electromagnet Fields, Gaithersburg, MD 20899 USA.

This paper presents a new model that refines the multimedia documents for mobile environments while integrating information technology components to address strict requirements. We present new ways to structure and represent the multimedia content to fit into the traditional document framework so that we can serve the document for an alternative presentation ordering, cross-media translation, and scalable renditions. We propose techniques that utilize the structure of documents across several levels in a manner that applies semantic description to provide scalable multimedia services. A modern multimedia document consumption scenario is introduced where a mobile collaborative working environment is demonstrated utilizing the proposed techniques.

The velocity is calculated by using the travel time determined from the phase differences between the spectra of two successive signals. In practice, the frequency spectra are estimated using Discrete Fourier Transforms (DFT). However, using the DFT requires sampling and windowing of the received waveforms. We present a comprehensive and self-consistent method of analysis that allows one to derive a relation for the uncertainty of the phase velocity as a function of the sampling-parameters, window-shape, noise-variance and travel-time. We compare the results of our method with results for a pulse-echo, 5 MHz measurement of the velocity on a 25.4 mm thick steel specimen. For a signal-to-noise ratio of 40 dB, the theoretically predicted and experimentally determined imprecisions are 0.07% and 0.05% respectively. C1 Natl Inst Stand & Technol, Boulder, CO 80303 USA.

AB We have taken a NIST molecular dynamics simulation program (md3), which was configured as a single sequential process running on a CRAY C90 vector supercomputer, and parallelized it to run in a distributed memory message passing environment. Since portability was a major concern during parallelization, we used the Message Passing Interface (MPI) standard. The features of MPI provide a basic set of interprocess communication primitives on many architectures. The parallel md3 program has two basic algorithms resulting in a MPMD (Multiple Program Multiple Data) structure, versus the more common SPMD (Single Program Multiple Data) structure, and has the potential to exploit heterogeneous processing. For any given number of nodes we have devised an equation to determine the initial node allocation among these multiple programs which yields near optimal load balance. We also dynamically manage the load balance between processes to correct for run time variations and to achieve better performance. We compare the performance of this MPMD parallel code run on a range of distributed memory machines (an IBM SP2, a cluster of Pentium Pros, and a cluster of SGI Indigo2s with the R10000 processor) against the original code performance on the Cray. In addition to better performance, the code on distributed memory machines offers an ability to scale the problem size based upon the combined memory size of the host systems.

The monitor provides a series of high-resolution timers, and the ability to monitor the utilization of the PCI bus. We also demonstrate how the monitor can be integrated with online performance monitoring tools such as the Paradyn parallel performance measurement tools to improve the overhead of key timer operations by a factor of 25. In addition, we present a series of case studies using the MultiKron hardware performance monitor to measure and tune high-performance parallel computing applications. By using the monitor, we were able to find and correct a performance bug in a popular implementation of the MPI message passing library that caused some communication primitives to run at one half of their potential speed.

All three methods utilize common flexure specimens and test fixtures. Versailles Advanced Materials and Standards (VAMAS) round robin data have contributed to precision estimates for two of the three methods. This standard was developed jointly by ASTM Committees C-28, Advanced Ceramics and E-08, Fracture and Fatigue. This paper presents background information for this standard including the rationale for the choice of the three methods and some of the specifications. PS 070-97 will be converted to a full-consensus standard in 1998. Standard Reference Material (SRM) 2100 with a certified fracture toughness is in preparation.

Once a part exceeds its allowable strain, its functional integrity is lost. Although most ceramics are designed to a brittle failure criterion, silicon nitride at the temperatures expected in gas turbines is an exception to this generality. In the temperature range and at the stresses expected in gas turbines, silicon nitride can easily exhibit strains to failure that exceed 1 %. Because an allowable strain of only 0.5 % is used for gas turbine design, the necessity of a strain-determined design methodology must be considered. In this paper the consequences of creep on design are considered for an allowable strain of 0.5 % and a reliability of one failure in 10,000. For a given stress and failure time, we show that reductions in operating temperature by as much as 40 degrees C are needed when strain rather than creep rupture is considered as the failure criterion. An additional 25 degrees C reduction is needed to assure the reliability level to one part in 10,000. C1 Natl Inst Stand & Technol, Gaithersburg, MD 20899 USA.

Satellites have long been used to support forecasting of intensive weather hazards such as tropical cyclones, severe storms and flash flooding. However, although there have been numerous research and operational demonstrations that illustrate the potential usefulness of EO satellite data for a broader range of hazards, the operational application of these data to other hazards is rare. To address this opportunity, the Committee on Earth Observation Satellites (CEOS) has initiated a project on disaster management support. Within that project, several hazard teams have been formed. These teams are charged with compiling user requirements; identifying shortcomings and gaps in the provision of required satellite data; and developing recommendations for alleviating them. This paper describes that project - it's objectives, approach, and structure. C1 NOAA, Washington, DC 20233 USA. RP Wood, HM (reprint author), NOAA, 4700 Silver Hill Rd, Washington, DC 20233 USA.

For example, the mechanical properties of a nylon-6 layered-silicate nanocomposite, with a silicate mass fraction of only 5 %, show excellent improvement over those for the pure nylon-6. The nanocomposite exhibits a 40 % higher tensile strength, 68 % greater tensile modulus, 60 % higher flexural strength, and a 126 % increased flexural modulus. The heat distortion temperature (HDT) is increased from 65 degrees C to 152 degrees C (2). Previously, we reported on the flammability properties of delaminated nylon-6 layered silicate nanocomposites and intercalated polymer layered-silicate nanocomposites prepared from polystyrene, PS, and polypropylene graft-maleic anhydride, PP-g-MA (3,4). Here, we will briefly review these results and report on our initial studies of the flammability of thermoset PLS nanocomposites: intercalated vinyl ester silicate and intercalated epoxy silicate nanocomposites.

Composite Al rings were fabricated from high-purity (99.995%) Al and high-strength Al alloy (6061-T6) to simulate the mechanical and electrical characteristics of the stabilizer during fatigue tests in liquid He. To simulate the magnet operating conditions, as the coil is periodically charged and discharged, one test was conducted where a composite ring was subjected to fatigue at 4 K, with the peak hoop stress held constant during the test and the ring's electrical resistance periodically measured at 0 and 4 T. For comparison, a second fatigue test was conducted on a similar ring where peak hoop strain was held constant. In both tests the initial peak strain was 0.21%. In the constant-strain test, the increase in resistivity at 4 T after 4000 fatigue cycles was 40% greater than for the constant-stress test, indicating a significant strengthening of the composite through work-hardening of the high-purity Al. These results, applied to the design of AI-stabilized magnets, allow a substantial reduction in the required quantity of high-purity-Al stabilizer and in the magnet's cost.

Square planar junctions with side widths of 2, 4, 8, and 16 mu m were fabricated ex situ. Annealing was carried out at constant sample temperature for 10 minutes in atmospheric pressure of oxygen. The junction conductance characteristics were measured after each annealing and the process was repeated at progressively higher annealing temperatures, up to 650 degrees C. Before oxygen annealing, the junctions had contact resistivities of about 10(-4) Omega cm(2) or greater. The contact resistivity was unchanged for annealing temperatures below 300 degrees C. It decreased rapidly in an annealing temperature range from 300 degrees C to 450 degrees C. We found that 600 degrees C was a practical upper limit for annealing, at which temperature a contact resistivity in the 10(-6) Omega cm(2) range may be achieved. We conclude that annealing-induced Au diffusion along grain-boundaries was responsible for the reduction in the contact resistivity. C1 Natl Inst Stand & Technol, Boulder, CO 80303 USA.

Multifilamentary Nb-Ti and Nb3Sn samples were used in this study. I-C(T) measurements above 5 K are difficult because these measurements need to be done in helium gas and the heat generated during the measurement and conducted down high-current leads can raise the sample temperature significantly. This creates a large uncertainty and perhaps a sample dependent bias in the sample temperature that occurs even if the measurements are made meticulously I-C(T) measurements at a constant magnetic field are needed to determine the temperature margin of magnet applications and performance data for cryogen-free applications.

As a result of these advances, the NIST disseminated version of ITS-90 has recently undergone small adjustments below 83.8058 K. These adjustments are all at the sub-millikelvin level and reflect the inclusion of recent data on ITS-90 realizations and intercomparisons of reference thermometers. Specifically developments in the realization of ITS-90 fixed points, gas thermometry, and vapor pressure thermometry at NIST have significantly improved our knowledge of scale non-uniqueness and dissemination uncertainty in the lowest temperature ranges. We briefly describe the present status of ITS-90 realizations at NIST and which definitions are currently being disseminated. Our procedures for calibration of standard reference thermometers for cryogenic use are reviewed and our updated assessments of calibration uncertainties are presented. These include calibration of Standard Platinum Resistance Thermometers (SPRTs) of the capsule type between 13.8033 K and 273.16 K, and of Rhodium-Iron Resistance Thermometers (RIRTs) between 0.65 K and 83.8058 K. In addition, we preview a new Standard Reference Material(R) (SRM(R)) project which will make available "as defined" ITS-90 calibrated capsule SPRTs through the NIST SRM program. These continuing advances in scale realization and dissemination at NIST will improve the accuracy and availability of ITS-90 standards throughout the cryogenic engineering community.

This system uses a mixed-gas Joule-Thomson (J-T) refrigerator to cool the tip of a catheter that can be inserted into the body through the large veins leading into the heart. The cryogenic catheter is intended to treat heart arrhythmia characterized by an abnormally rapid heart rate, although the system has a wide variety of other medical applications. Approximately 2 million people in the U.S, suffer from rapid-rate heart arrhythmia. Catheter therapy has proven to be a more effective and less expensive method of treatment than alternatives such as drugs or surgery. A cryogenic catheter has significant advantages over existing catheters used in this form of therapy. The catheter has coaxial tubes for the high and low pressure streams with a miniature heat exchanger and J-T orifice at the catheter tip. The high pressure is maintained at 2.5 MPa. The largest diameter is 3 mm, the length is 90 cm, and all but the last 10-20 mm is flexible. The gas mixture has been optimized for the required operating conditions using nonflammable and low ozone depletion gases. Low cost techniques have been incorporated into the fabrication of the cold tip so that each catheter can be disposable. Several prototype catheters have been built. No-load temperatures down to 85 K were achieved with the cold tip exposed to ambient air. Using room temperature gelatin to simulate tissue heat loads, catheter tip temperatures of 160 to 175 K have been achieved, and ice balls about 26 mm in diameter weighing 11 g were created. We estimate that ice balls about 10 mm in diameter weighing 1.5 to 2.0 g are required to treat ventricular arrhythmia. Although the heat load in our experiments was less than the in vivo load, we think the current refrigeration power is sufficient to meet the clinical requirement.

Screens are stacked in a fiberglass-epoxy cylinder, which is 24.4 mm in diameter and 55 mm in length. The cold end of the stacked screens is cooled by a Gifford-McMahon (GM) cryocooler at cryogenic temperature, and the hot end is maintained at room temperature. Heat conduction through the screens is determined from the temperature gradient in a calibrated heat flow sensor mounted between the cold end of the stacked screens and the GM cryocooler. The samples used for these experiments consisted of 400-mesh stainless steel screens, 400-mesh phosphor bronze screens, and two different porosities of 325-mesh stainless steel screens. The wire diameter of the 400-mesh stainless steel and phosphor bronze screens was 25.4 mu m and the 325-mesh stainless steel screen wire diameters were 22.9 mu m and 27.9 mu m. Standard porosity values were used for the experimental data with additional porosity values used on selected experiments. The experimental results showed that the helium gas between each screen enhanced the heat conduction through the stacked screens by several orders of magnitude compared to that in vacuum. The conduction degradation factor is the ratio of actual heat conduction to the heat conduction where the regenerator material is assumed to be a solid rod of the same cross-sectional area as the metal fraction of the screen. This factor was about 0.1 for the stainless steel and 0.022 for the phosphor bronze, and almost constant for the temperature range of 40 to 80 K at the cold end.

The same pulse tube was used for all the experiments and measured 4.76 mm in diameter and 46.2 mm in length. A commercial linear compressor with a swept volume of 4 cm(3) was used in these experiments. The operating conditions were held constant at a mean pressure of 2.0 MPa and a frequency of 54 Hz. Using finite difference software called REGEN3.1, developed at NIST, and recent experiment results, we optimized a series of regenerators based on dimensions, materials and screen packing. The values used for calculating the thermal conduction through stacked screens by REGEN3.1 were based on recent experimental results from NIST. The regenerator tubes were designed using 316 stainless steel and titanium materials. The regenerator matrices investigated were 400-mesh and 500-mesh stainless steel screen. The valve settings for both orifices were adjusted to minimize the no-load temperature for all regenerators. A cooling capacity curve from 0 to 3 W was also determined. The performance of the pulse tube refrigerator using the different regenerators is discussed. The experimental results from the various regenerators are evaluated and compared with their corresponding numerically calculated coefficient of performance (COP) and regenerator design as determined by REGEN3.1.

Both methods employ the ceramic under test as a dielectric resonator. In the first method, in addition to the use of TE011 or TE01 delta resonant modes, higher-order TE0 gamma delta resonances are measured in a parallel-plate dielectric resonator system. Typical total estimated uncertainties in measured permittivity are less than +/-0.3%, and dielectric loss tangent measurements may be performed with an uncertainty of +/-1 x 10(-5). In the second technique, resonant frequencies and Q factors of whispering-gallery modes are measured in the sample under test. Because the modal energy of these waves is concentrated within a small region near the concave cylindrical surface of the sample under test, measured whispering-gallery modes are insensitive to the presence of conductor losses, particularly for higher azimuthal mode numbers. Radiation losses are also negligible, so the latter technique is the most accurate for measurements of permittivity, dielectric loss, and temperature coefficient of resonance for very low loss ceramic materials. With the use of both quasi-TE and quasi-TM whispering-gallery mode resonances, dielectric measurements of uniaxially anisotropic materials may be performed. Both methods permit relatively broadband dielectric characterization of a single sample. C1 Natl Inst Stand & Technol, Div Electromagnet Fields, Boulder, CO 80303 USA.

Both the inclusions and host matrix of the composite ceramic may be magnetically permeable and possess dielectric and magnetic loss. The modified Maxwell-Garnett formulation does not yield symmetric characterization and differs from other rules in that the loading particle permeability and permittivity properties are modified by a complex amplitude and phase wave number function that quantifies how well electromagnetic fields penetrate the loading material. It may be used to give both upper and lower bounds for the effective permittivities and permeabilities of the composite and yield accurate estimates of bulk electric and magnetic properties for low volumetric loading, once measurements are performed on the dielectric and magnetic properties of the individual constituent phases. A Bruggeman model for a two-phase composite leads to a symmetric mixing rule, where effective dielectric and magnetic properties are evaluated from a complex quadratic involving the electric and magnetic properties of the individual constituents and the respective volume fractions. The Bruggeman model may be used for frequency-dependent dielectric property corrections of polycrystalites to theoretical density. Application to a ceramic LaAlO3 sample having a density 20% less than theoretical yielded dielectric-results that differed from single-crystal measured permittivities by no more than 4%.

The models are assessed in light of the results of mass spectrometric and optical imaging observations of the plume. Model predictions of film composition are compared with the results of microscopic compositional analysis across a deposited BaTiO3 film. The spatial distributions of the relative abundance of total Ba and Ti were a particular focus of this study, with the latter model giving the best agreement with experiment. The Monte Carlo simulation results indicate that the incoming concentration ratio of total Ba to Ti, across the substrate surface, is strongly modified by gas collisions within a compressed region that forms between the infalling plume and the substrate surface, and also by momentum exchange (scattering) between the lighter plume species and the added background gas.

This new system allows daylight data collection, whereas our previous HeNe-laser-based system operated only at night. Additionally, the new system incorporates real-time correction of ship motion to allow operation on a moving ship. This paper provides an overview of the instrument design and the scientific objectives of its future deployment. A specific scientific objective discussed here is determining the connection between the fractal dimension of the laser-glint process and surface roughness. Evidence is shown here from previously acquired laser-glint data that the laser-glint-count process is fractal, with a dimension that appears to vary with surface roughness. Plans are outlined for deployment of the new laser-glint sensor with fractal signal processing for remotely sensing surface roughness. C1 NOAA, Environm Technol Lab, Boulder, CO 80303 USA.

The puff modeling simulation results are compared with data obtained following a single 3-hour late-afternoon tracer release conducted on April 19, 1977 near Idaho Falls, Idaho, USA. Samplers were positioned on arcs at downwind distances of 3.2, 48 and 90 km. Low-level instrumented masts provided hourly values of wind and temperature at 17 sites within the experimental area. Hourly rawindsondes were available 600 m northwest of the release point. And hourly pibals provided winds aloft at three other sites within the area. In this discussion, alternative combinations of the available meteorological data were used to assess the differences to be seen in the simulation results. Analysis of the results suggests that the simulated lateral dispersion along each are was best characterized when all of the surface and upper wind observations were used, and that the position of the simulated maximum on each are was poorly characterized regardless of data used.

In contrast to the results observed for cocaine, SFE recoveries of BZE were poor from all matrixes and under all conditions studied, Its increased polarity, the presence of an additional binding site, and the possibility of multiple charged states suggest that poor BZE recoveries may be due to both poor analyte solubility and failure to desorb the analyte from hair binding sites under the conditions employed.

This is particularly true for the polar regions, where the observational arrays are sparsely distributed. In high southern latitudes, a comprehensive assimilation of all available observations, including satellite data, is necessary for an accurate depiction of the atmospheric circulation. Recent studies have found the operational analyses of the European Centre for Medium-range Weather Forecasts to be superior to those of other weather-forecasting centers in depicting the large-scale atmospheric circulation patterns over Antarctica. "Re-analysis" programs at major weather-forecasting centers have produced atmospheric numerical analyses using a "frozen" data-assimilation system. These projects have also derived precipitation and evaporation fields using an ensemble of short-term forecasts. From these new sources, Antarctic P - E (precipitation minus evaporation/sublimation) is compared and evaluated against the long-term glaciological synthesis, as well as results fi om previous studies. The comparisons indicate significant regional disagreements exist between P - E from the re-analysis forecasts and the glaciological data. For the ensemble forecasting method, the continental-average evaporation is the largest area of uncertainty and differs by art order of magnitude between the re-analysis datasets. This finding supports the use of the atmospheric moisture budget fur determining P - E collectively in atmospheric diagnostic studies for Antarctica.

Specifically, we have constructed a nonlinear parameter estimation reasoner (NPER) for finding parameter values that match an ordinary differential equation (ODE) model to observed data. Qualitative reasoning is used within the NPER, for instance, to intelligently choose starting values for the unknown parameters and to empirically determine when the system appears to be chaotic. This enables odrpack, the nonlinear least-squares solver that lies at the heart of this NPER, to avoid terminating at local extrema in the regression landscape. odrpack is uniquely suited to this task because of its efficiency and stability. The NPER's robustness is demonstrated via a Monte Carlo analysis of simulated examples drawn from across the domain of dynamics, including systems that are nonlinear, chaotic, and noisy. It is shown to locate solutions for noisy, incomplete real-world sensor data from radio-controlled cars used in the University of British Columbia's soccer-playing robot project. The parameter estimation scheme described in this paper is a component of pret, an implemented computer program that uses a variety of artificial intelligence techniques to automate system identification - the process of inferring an internal ODE model from external observations of a system - a routine and difficult problem faced by engineers from various disciplines.

Prior to 1990, altimeter data resolved only tectonic lineaments, some seamounts, and some aspects of mid-ocean ridge structure. New altimeter data available since mid-1995 resolve 10-km-scale structures over nearly all the world's oceans. These data are the basis of new global bathymetric maps and have been interpreted as exhibiting complexities in the sea floor spreading process including ridge jumps, propagating rifts, and variations in magma supply. This chapter reviews the satellite altimetry technique and its resolution of tectonic structures, gives examples of intriguing tectonic phenomena, and shows that structures as small as abyssal hills are partially resolved. A new result obtained here is that the amplitude of the fine-scale (10-80 km) roughness of old ocean floor is spreading-rate dependent in the same way that it is at mid-ocean ridges, suggesting that fine-scale tectonic fabric is generated nearly exclusively by ridge-axis processes.

As we learn more about the science of the problem, the sense of controversy about the state of the science has actually increased, sharply so over the past decade. This essay highlights the fundamental aspects of the science underlying global warming. The vital roles of climate models and of climate data in sharpening scientific understanding are featured. Finally, the roles of controversy in the science and the sociology of this problem are addressed, and new insights are offered on the inevitability of future major conflicts and controversies as society begins to deal with the need to either reduce the use of fossil fuels considerably or adapt to substantial changes in Earth's climate.

These models have been applied successfully to situations in which the physical phenomena of interest have a length scale commensurate with the thickness of the interfacial region (e.g. near-critical interfacial phenomena or small-scale flows such as those occurring near contact lines) and fluid flows involving large interface deformations and/or topological changes (e.g. breakup and coalescence events associated with fluid jets, droplets, and large-deformation waves). We discuss the issues involved in formulating diffuse-interface models for single-component and binary fluids. Recent applications and computations using these models are discussed in each case. Further, we address issues including sharp-interface analyses that relate these models to the classical free-boundary problem, computational approaches to describe interfacial phenomena, and models of fully miscible fluids.

Adaptive multilevel methods combine multigrid iteration with adaptive refinement to produce fast O(N) solutions on sequential computers, where N is the number of grid elements. However, many problems of interest require parallel computers. While adaptive refinement, multigrid and parallel computers are individually achieving widespread use in applications, the combination of all three is still a research topic. In this paper we describe the full domain partition (FuDoP) distribution of adaptively refined grids over a distributed memory parallel computer. In the FuDoP approach, each processor has a compatible grid that covers the full domain, but with refinement confined to the processor's partition of the total grid. Outside the partition area, refinement is limited to that required for compatibility and leads to a small number of extra grid elements. With the FuDoP distribution, a parallel multigrid method can maintain a multigrid rate of convergence with only two communication steps per V-cycle. FuDoP also accommodates parallel implementation of adaptive refinement and partitioning. (C) 1998 Elsevier Science B.V.

Both environmental and genetic factors can contribute to the great diversity in test form and composition in benthic foraminifera. Yet, small specimen size and the remoteness of the deep-sea environment have limited our ability to describe the relative influence of these biological and chemical factors. The use of fossilized foraminiferal tests as paleo-indicators requires that we understand the controls on test composition. Test wall morphology and composition were examined in foraminifera that colonized experimental substrates deployed on a seamount in the central North Pacific. Three types of agglutinated forms were identified. A triserial (Eggerella-like) and two-chambered (Hyperammina-like) form contained a Ca-rich (CaCO(3)) precipitate and the chamber walls of an encrusting two-chambered form was Ba-rich (BaSO(4)). We discuss the composition of these biologically precipitated minerals in the context of the environmental conditions during the life of these foraminifera.

The next cycle, numbered 23, appears to be under way. Small geomagnetic storms have continued through the time of minimum and to the present. The 10.7 cm radio flux (used as a surrogate for EUV flux) has increased only slightly over the past few months. At some point in the near future sunspot numbers and the 10.7 cm flux will begin a consistent rise, marking the end of a period around minimum when these parameters fluctuate near their smallest values. In anticipation of Cycle 23, The NOAA Space Environment Center (SEC), with support from NASA, convened a group of experienced solar experts in the fall of 1996 for the purpose of surveying forecasts for the new cycle and to recommend a forecast or group of forecasts for maximum smoothed 10.7 cm flux and sunspot numbers. That panel's predictions are for a maximum smoothed 10.7 cm flux of 205 to occur between January 1999 and June 2001 and with a smoothed sunspot number maximum of 160. For both 10.7 cm flux and sunspot numbers, there is expected to be an extended period of one to three years around maximum when the observed values, having risen rapidly from minimum, enter a sustained period of high readings. Using standard atmospheric models, the periodic variation in atmospheric density associated with the variations of EUV flux (as represented by 10.7 cm radio flux) and Ap will be illustrated. Verification of one-to three-day forecasts of geomagnetic activity and solar 10.7 cm flux issued by SEC are included in the paper. C1 NOAA, Space Environm Lab, Boulder, CO 80303 USA.

The results of data analysis of the ozone profiles are presented, with a focus on the seasonal cycle in tropospheric ozone. The results show that the tropospheric ozone column has an obvious maximum in spring and a minimum in summer. The former is a common feature at many locations in the Northern Hemisphere. The summer minimum is attributed to the onset of the summer monsoon when air flow from the Asian continent is replaced by air from the South China Sea or the tropical Pacific. The tropospheric ozone has an important influence on the seasonal cycle of total ozone at Hong Kong. The seasonal cycle of ozone mixing ratio below 2 km is bimodal with ozone peaks in spring and autumn. A frequently observed feature in late autumn and winter is a relative minimum of ozone mixing ratio (as low as 30-40 ppbv) in the upper troposphere (from about 9 to 16 km). Trajectory analysis shows this relative minimum of ozone is associated with air masses coming from the tropical region. It is proposed that the East Asia local Hadley circulation is responsible for this feature. (C) 1977 Elsevier Science Ltd. C1 Hong Kong Polytech Univ, Dept Civil & Struct Engn, Kowloon, Hong Kong.

In contrast to previous, entirely empirical compilations, ours uses advanced theoretical calculations combined with a sparse network of accurate experimental measurements. The theoretical results closely reproduce high quality experimental data, where they are available, for atoms from Z = 22 to Z = 90. This suggests that the theoretical estimates are potentially useful in cases where adequate experimental data are absent. Above and below this range, problems emerge which need further examination both theoretically and experimentally. C1 NIST, Phys Lab, Atom Phys Div, Gaithersburg, MD 20899 USA.

Such efforts are no longer possible due to the massive amounts of data produced each year. In order to design smaller, more focussed, and shorter term data efforts, a workshop was held at NIST, during which the most pressing immediate needs of various user communities were described in some detail. While these needs are now relatively clear, as indicated in the overview below, a good algorithm for prioritizing the needs of the very disparate user groups did not emerge from the workshop.

The three-dimensional structure and heme geometries were compared to those of deoxyhemoglobin and other partially and fully oxidized hemoglobins [R. Liddington, Z. Derewenda, E. Dodson, R. Hubbard, G. Dodson, J. Mel. Biol. 228 (1992) 551]. The heme geometries of the alpha-subunits are consistent with those observed in oxidized structures, The proximal histidines of the cu-subunits move toward the heme plane shifting the F-helix and FG-corner ina manner observed for partially oxidized human hemoglobin. This supports the hypothesis that these perturbations may precede the T-to R-state transition, Circular dichroism studies comparing DecHb and natural human hemoglobin in the deoxy and CO ligated forms confirm that the conformations of the deoxy forms are identical, but the ligated forms have slight differences in the solution structures. DecHb is found to be more resistant to autoxidation than natural hemoglobin. The time course of autoxidation of DecHb shows that it is virtually absent for the first 1500 min followed by a rapid increase. Thus, the discovery of the oxidation of the cu-subunits in the deoxy-crystals is quite unexpected. The data confirm that ligation of the alpha-subunits precedes that of the beta-subunits. This may suggest a low ligand affinity of the alpha-diligated form of hemoglobin. (C) 1998 Elsevier Science B.V. C1 Univ Maryland, Sch Med, Dept Biol Chem, Baltimore, MD 21201 USA.

Criteria are developed to provide an objective means of determining when random swimming can be neglected, potentially reducing the model complexity and field research necessary to adequately address a given scenario. The models investigated indicate that horizontal random swimming does not contribute significantly to the displacement of oceanic larvae relative to their expected positions, but they do not rule out the importance of vertical random swimming. The models also show that horizontal swimming by larger pelagic organisms could easily dominate turbulence in the ocean and may be important to larvae in less turbulent bodies of water such as bays and lakes.

However, in the two regions where reasonably reliable records exist (the North Atlantic and the western North Pacific), substantial multidecadal variability (particularly for intense Atlantic hurricanes) is found, but there is no clear evidence of long-term trends. Efforts have been initiated to use geological and geomorphological records and analysis of oxygen isotope ratios in rainfall recorded in cave stalactites to establish a paleoclimate of tropical cyclones, but these have not yet produced definitive results. Recent thermodynamical estimation of the maximum potential intensities (MPI) of tropical cyclones shows good agreement with observations. Although there are some uncertainties in these MPI approaches, such as their sensitivity to variations in parameters and failure to include some potentially important interactions such as ocean spray feedbacks, the response of upper-oceanic thermal structure, and eye and eyewall dynamics, they do appear to be an objective tool with which to predict present and future maxima of tropical cyclone intensity. Recent studies indicate the MPI of cyclones will remain the same or undergo a modest increase of up to 10%-20%. These predicted changes are small compared with the observed natural variations and fall within the uncertainty range in current studies. Furthermore, the known omissions (ocean spray, momentum restriction, and possibly also surface to 300-hPa lapse rate changes) could all operate to mitigate the predicted intensification. A strong caveat must be placed on analysis of results from current GCM simulations of the "tropical-cyclone-like" vortices. Their realism, and hence prediction skill (and also that of "embedded" mesoscale models), is greatly limited by the coarse resolution of current GCMs and the failure to capture environmental factors that govern cyclone intensity. Little, therefore, can be said about the potential changes of the distribution of intensities as opposed to maximum achievable intensity. Current knowledge and available techniques are too rudimentary for quantitative indications of potential changes in tropical cyclone frequency. The broad geographic regions of cyclogenesis and therefore also the regions affected by tropical cyclones are not expected to change significantly. It is emphasized that the popular belief that the region of cyclogenesis will expand with the 26 degrees C SST isotherm is a fallacy. The very modest available evidence points to an expectation of little or no change in global frequency. Regional and local frequencies could change substantially in either direction, because of the dependence of cyclone genesis and track on other phenomena (e.g., ENSO) that are not yet predictable. Greatly improved skills from coupled global ocean-atmosphere models are required before improved predictions are possible. C1 Royal Melbourne Inst Technol, Bundoora, Vic 3083, Australia.

A simple energetically consistent model was integrated for a simulated time of approximately 1 month. Analysis of the model results clarified the respective roles of the synoptic-scale eddies (cyclones-anticyclones) and mean meridional circulation in the maintenance of the upper-level westerlies and the surface wind regimes. Furthermore, the modeled cyclones clearly linked surface frontogenesis with the upper-level Charney-Eady wave. In addition to discussing the model results in light of the controversy and ferment that surrounded general circulation theory in the 1940s-1950s, an effort is made to follow Phillips's scientific path to the experiment.

The management community, academic researchers, and others, spurred on by a growing body of concerned ocean resource users, have begun to grapple with the notion of ocean governance based on the principles of ecosystem management. Marine protected areas (MPAs) are one key element in this growing era of bigger thinking and in the context of national ocean governance discussions. The inclusion of marine protected areas initiatives in the ocean governance discussions is a positive step toward integrating ecosystem principles within this governance structure, and a number of valuable lessons can be gleaned from taking a look at some of these efforts. This paper focuses on one such program, NOAA's National Marine Sanctuary Program (NMSP), and provides some insights into its evolution and innovative efforts to foster ecosystem management in and around these coastal and ocean areas. This discussion will profile new ideas being formulated by the NMSP which address how MPAs such as these sanctuaries can provide opportunities for catalyzing broader ecosystem management initiatives and how they can serve as laboratories for developing innovative and alternative ocean governance mechanisms. Finally, the paper will examine the critical role of forging effective partnerships to make this essential coordination and collaboration a reality for successful ocean governance.

Reyes, located north of San Francisco, and Cambria, at the southern end of the Big Sur coast, there are over 30 managed coastal areas. These areas are designated as sanctuaries, reserves, preserves, refuges, wildlife areas, and parks. A review of these coastal programs found they have similar goals and overlapping jurisdictions. However, programs that incorporated scientific advisory groups had more current management plans, a broader view of resource management alternatives, larger research budgets, and a wider variety of research activities. These programs were developed, in large part, independently of each other and based on local history more than a comprehensive resource management vision. There is great opportunity for collaboration between these programs to improve their individual and common goals. The Monterey Bay National Marine Sanctuary (MBNMS), encompassing most of the coastline in central California, has a programmatic structure of working groups and advisory councils that take advantage of insight from academic scientists, multiple resource management agencies, user group representatives, and education specialists. The MBNMS may be the forum for improved collaboration between programs and an avenue to academic scientists in the development of science plans and enacting necessary research.

The most widely used organizing tool for dealing with natural and environmental resource choices is benefit-cost analysis, which offers a convenient way to carefully identify and array, quantitatively if possible, the major costs, benefits, and consequences of a proposed policy or regulation. However, a major shortfall of benefit-cost analysis has been the difficulty of quantifying both benefits and costs of actions that impact environmental assets not normally or regularly bought and sold in markets. Economists and other social scientists have put a great deal of effort into addressing this shortcoming by developing techniques to quantify these non-market benefits. To make that link, NOAA has undertaken a series of Regional Environmental Valuation Workshops to introduce and illustrate concepts of environmental valuation to state and local coastal planners and managers, fishery managers, and those concerned with the broad range of coastal sustainability issues. This paper briefly summarizes the Handbook developed for these Workshops. The Handbook is intended for non-economists and addresses basic concepts of economic value such as willingness-to-pay and other tools often used in decision making such as cost-effectiveness analysis, economic impact analysis, and sustainable development.

The overall goal of the program is to protect and enhance natural resources in a wide array of habitats within its boundaries. MBNMS achieves this goal through a responsive integrated coastal management approach that promotes cooperation between the Sanctuary office and other public agencies and capitalizes on the expertise of individuals and interest groups that share a common interest in preserving the natural resources of the Sanctuary. The structure of the program involves integrating a small Sanctuary staff with various management agencies and interest groups. An example of this integration includes coordination with the Sanctuary Advisory Council, made up of twenty-four representatives from public agencies and user interests plus specific working groups for research (22 marine institutions), education (20 educational institutions) and conservation (15 conservation organizations). The Sanctuary also is involved in developing a water quality protection program for the region that presently involves twenty-seven different agencies plus interest groups. Additionally, the public has opportunities for input into the program through council meetings, through representatives from working groups or council members, and through contact with Sanctuary staff. The MBNMS program is linked nationally with eleven other Sanctuaries and twenty-six Estuarine Research Reserves through the Sanctuaries and Reserves Division in Washington DC. This integrated approach has addressed numerous issues ranging from assessing former military exclusion zones and improving water quality to facilitating multiple resource use conflicts such as shark chumming. In this manuscript, I will outline the structure and process of the MBNMS integrated management approach and provide examples of resource management issues that have been addressed.

Through the use of volunteers (citizen scientists) the Sanctuary directly educates hundreds of local constituents on marine resources and indirectly reaches 1000's of visitors to the Sanctuary each year. The volunteers collect data that will be used to protect the natural resources of the Sanctuary while they learn how to be responsible stewards of the Sanctuary. Through the use of volunteer monitors we can accomplish our research objectives: 1) to assess the gaps in the Sanctuary's information base that may affect our ability to manage the area; 2) conduct studies of species or marine communities to identify resources most at risk or in need of management attention; 3) promote the Sanctuaries as a site for management related marine research by providing financial and logistical support for scientific investigations that address critical marine resource protection issues; 4) design research projects that are responsive to management concerns and that contribute to improved management of the Sanctuary; 5) make effective use of research results by incorporating them into interpretive and resource protection programs; and 6) encourage information exchange and cooperation among all the organizations and agencies undertaking management related research in the Sanctuaries to promote more timely and informed management.

Natural mortality in salmon occurs in two main phases: juvenile stages experience high mortality during freshwater residency and pre-adult salmon experience high mortality in estuarine and ocean environments. Freshwater survivorship is well characterized and tends to be less variable than marine mortality. Sources of marine mortality are poorly known due to a lack of basic knowledge about post-smelt distributions and habits. Coherence patterns among regional and continental stock groups suggest broad scale forcing functions play a more important role in defining recruitment than mortality effects associated with individual rivers. The action of mesoscale regional environment is most prominent during the post-smelt year when survival, maturation, and migration trajectories are being defined. During the early weeks at sea, growth mediated survival defines recruitment patterns. A correlation between sea surface water temperature and survival has been observed for salmon stocks in the northeast Atlantic suggesting temperature either directly affects growth or modifies post-smelt behavior. Age at first maturity is controlled by environmental as well as genetic factors. The abundance of two seawinter spawners in North America is directly scaled to the size of overwintering thermal habitat in the northwest Atlantic, which suggests a link between maturation and environment.

The model was used to investigate changes in fishing behavior during a temporary ban on night fishing in 1992. The cycle of setting the net, fishing, and retrieving the net is modeled with different costs for each activity. The optimal controls generally consist of a bin threshold that signals the vessel to start fishing and a catch threshold that signals the vessel to stop fishing. A range of simple "rule of thumb" strategies generated nearly as much net revenue as the optimal control, indicating that the reward surface is flat in the region of the optimal control. A model with diel variation in catch rates caused the vessel to adjust bin and catch thresholds through the day to stockpile fish during the daylight hours and then to cut back on fishing at night when the catch rate is lower. With a ban on night fishing, vessels accumulated fish to a greater extent during the day, but daily net revenue did not decline significantly. Operational models of fishing have important applications in evaluating the consequences of management actions on the fishing industry. Regulations that ignore the constraints and trade-offs under which fishing vessels operate may fail to achieve their intended purposes, or may have unforseen adverse consequences.

While fisheries scientists have investigated the various elements of habitat and how they affect Atlantic salmon growth and survival, these studies typically focus on requisite requirements for a single life history stage. Current advances in our understanding of salmonid populations in lotic systems indicates that ignoring the spatial positioning of different habitats and dispersal capabilities of fish between them may affect estimates of habitat quality and production of juvenile Atlantic salmon. Using the concepts of juxtaposition and interspersion, we hypothesize that discrete functional habitat units (FHU) occur within river systems and that the spatial structure of FHU affects fish production. We present a method to delineate FHU using habitat maps, fish ecology, and spatial habitat characteristics. Utilizing a simulation model, we illustrate how modeling FHU structure of spawning and rearing habitat in a river system can improve our understanding of juvenile Atlantic salmon production dynamics. The FHU concept allows a flexible approach to more comprehensive analyses of the impacts of habitat alterations, seasonal habitat shifts, and spatial ecology of salmonids at various scales.

From a biological perspective, the appropriate conservation unit for Atlantic salmon is the Evolutionary Significant Unit (ESU). As conservation decisions will rarely be based solely on biological information, the Operational Conservation Unit (OCU) is defined as resulting from the interplay between biological requirements and socio-economic issues. A multi-scale habitat inventory of Atlantic salmon rivers to know what their status is relative to historical conditions is the first step in a functional conservation plan. The viability of salmon populations may be assessed according to 6 variables: abundance, resilience, age and size structure, sex ratio, spatial and geographical distribution. A genetically viable population possesses the species' evolutionary legacy and the genetic variation on which future evolutionary potential depends. Four factors important to monitoring changes in a population's genetic health are genetic diversity, effective population size, genetic bottlenecks and founder effects and gene flow. Implementation of a conservation plan must be proactive to maintain the quality of the OCUs. Commercial and recreational fisheries need to be limited and several case studies are reviewed. The importance of avoiding the introduction of exotics and minimizing the impact of sampling methodology, as well as the pitfalls of plantings eggs, fry, or parr, are addressed. Finally, the importance of fostering public awareness of the value of conservation is essential to apply the political pressure necessary to preserve natural resources.

However this is not the case for a solid composed of cubic molecules such as solid cubane. The cubic structure of the cubane molecule gives rise to many unusual solid state properties. Here we present a brief review of our X-ray and neutron scattering studies along with our model calculations of the structure and lattice dynamics of solid cubane. The low-temperature phase (below the transition temperature of 394 K) is rhombohedral with alpha = 72.69 degrees and a = 5.20 Angstrom. Surprisingly, the crystal structure of cubane in the orientationally-disordered phase is not cubic, but instead remains rhombohedral with alpha=103.3 degrees, far from the fee value of 60 degrees. The jump in lattice constant at this transition is 0.05 Angstrom, which corresponds to a 5.4% volume expansion, among the largest ever observed. Neutron inelastic scattering measurements indicate that the librons lie higher in energy than do the phonons, but that they soften rapidly with increasing temperature. Remarkably, model calculations predict the correct low and high-temperature crystal structures, and reveal cubane to be a text-book example of a system with anisotropic large-amplitude collective motions in the disordered phase.

The alumina and yttria-stabilized zirconia deposits studied were produced by two different atmospheric plasma-spraying methods - using gas-stabilized and water-stabilized plasma systems. The void microstructure of these deposits is dominated by two anisotropic void types - interlamellar pores and intralamellar cracks. There is also a broad distribution of spherical pores. The relative importance of these void systems is found to depend on the materials chemistry and on the spray technique. The surface area of the anisotropic voids was determined using SANS. By varying the spray technique and material, deposits with different dominant void systems were produced. The alumina deposits, manufactured by a high-power water-stabilized plasma-spray system, consisted of a microstructure dominated by intralamellar cracks; the same material deposited by a standard lower-power gas-stabilized plasma-spray system has about equal surface area in the intralamellar cracks and interlamellar voids. However, the zirconia deposit microstructure is always dominated by inerlamellar voids. C1 Acad Sci Czech Republ, Inst Plasma Phys, Prague 18200, Czech Republic.

Traditional reliability characterization techniques must be modified for very thin gate oxides that exhibit excessive tunneling currents and soft breakdown. As intrinsic reliability limits are approached by increasing chip temperature and electric fields, it becomes essential to fully understand the physical mechanism(s) responsible for gate oxide wear-out and eventual breakdown.

This comparison of the extracted depth profiles of the physical properties gives multiple perspectives on the thickness and interfacial characteristics of an SiO2 film on Si.

An accurate mechanical measurement of the wafer thickness, t, was required and two FTIR spectra were used: a high-resolution (Delta omega= 0.5 cm(-1)) yielding a typical channel spectrum dependent mainly on t and n(omega), and a low resolution (Delta omega = 4.0 cm(-1)) yielding an absorption spectrum dependent mainly on t and k(omega). Independent analysis of each spectrum gave initial n(omega) and k(omega) estimates which were then used together as starting point values for an iterative fit of the high- and low-resolution spectra successively. The accuracy of n(omega) and k(omega) values determined using this procedure is dependent upon the measurement error in the sample thickness, the absolute transmission values obtained from a sample-in and sample-out method, and the modeling of the influence of wafer thickness nonuniformity and the degree of incident light beam collimation. Our results are compared with previously published values for n(omega) and k(omega) in the 450 cm(-1) to 4000 cm(-1) spectral region. The error in n(omega) is < 1 part in the 10(4), a factor of IO better than published values. The k(omega) cm values are in good agreement with previous measurements except in the vicinity of the 610 cm(-1) peak feature where our values are similar to 20% lower.

One of the limiting factors in expanding the use of RTP is the accuracy of temperature measurements of the wafer during processing. We are developing a wafer for calibrating radiometric temperature measurements in RTP tools. The calibration wafer incorporates thin-film thermocouples with platinum I palladium (Pt/Pd) wire thermocouples welded to thin- film pads at the periphery of the 200 mm wafers. We have reduced the uncertainty of the temperature measurements up to 1200 K with this system. This has been accomplished by reducing the uncertainty due to the thermocouple itself and due to reduction of heat transfer near the junction. We report results of NIST calibrations of radiometers using Pt/Pd wire thermocouples welded to the thin films on the wafer and of calibrated type K thermocouples. The thin-film thermocouples were sputter deposited from high purity Pt, Pd and Rh. These thin-film thermocouples were calibrated by comparison with Pt/Pd wire thermocouples in a specially designed test cell at temperatures up to 1150 K. Radiometric temperature measurements were made on the calibration wafer in the MST RTP sensor test bed, using a commercial radiometer, and compared to those obtained from the thermocouple measurements. A model is presented to account for errors in the radiometric measurements due to stray radiation from the heating lamps, reflection of wafer emission from the chamber walls, and wafer emissivity. The calibrated type K thermocouples indicated temperature measurements within 4 K of both the Rh/Pt and Pt/Pd thermocouples on the 200 mm calibration wafer between 1000 K and 1150 K. The Pt/Pd thin films proved less durable than the Rh/Pt thin films and the limitations of these systems are discussed.

The accuracy of this inversion process is investigated for several different observation geometries using theoretical test data generated from known distributions. Optical CAT is applied to an ICP-GEC plasma source, with all the measurements made through a single large 152 mm diameter window.

The technique does not require the application of any voltage other than the rf bias voltage which is normally applied to wafers, thus avoiding any possible perturbations to the plasma. It relies on external measurements of the radio-frequency (rf) current and voltage at the wafer electrode. There is no need for any probe to be inserted into the plasma. To test the technique, comparisons were made with de measurements of ion current at a bare aluminum electrode, for argon discharges at 1.33 Pa, ion current densities of 1.3-13 mA/cm(2), rf bias frequencies of 0.1-10 MHz, and rf bias voltages from 1 V to 200 V. Additional tests showed that ion current measurements could be obtained by the rf technique in electronegative gases and when electrically insulating layers or wafers were on the electrode.

We have implemented on an AFM platform a new intermittent-contact scanning capacitance microscopy (IC-SCM) mode that is sensitive to the tip proximity to an IC interconnect, thus making it possible to image conductive structures buried under planarized dielectric layers. Such measurements can be used to measure IC metal-to-resist lithography overlay. The AFM conductive cantilever probe oscillating in a vertical plane was driven at frequency omega, below resonance. By measuring the tip-to-sample capacitance, the SCM signal is obtained as the difference in capacitance, Delta C(omega), at the amplitude extremes. Imaging of metallization structures was obtained with a bars-in-bars aluminum structure embedded in a planarized dielectric layer 1 mu m thick. We have also modeled, with a two-dimensional (2D) electrostatic field simulator, IC-SCM overlay data of a metallization structure buried under a planarized dielectric having a patterned photoresist layer deposited on it. This structure, which simulates the metal-to-resist overlay between sequential IC levels, allows characterization of the technique sensitivity. The capacitance profile across identical size electrically isolated or grounded metal lines embedded in a dielectric was shown to be different. The floating line shows capacitance enhancement at the line edges, with a minimum at the line center. The grounded line shows a single capacitance maximum located at the line center, with no edge enhancement. For identical line dimensions, the capacitance is significantly larger for grounded lines making them easier to image. A nonlinear regression algorithm was developed to extract line center and overlay parameters with approximately 3 nm resolution at the 95% confidence level, showing the potential of this technique for sub-micrometer critical dimension metrology. Symmetric test structures contribute to facilitate overlay data extraction. C1 NIST, Div Semicond Elect, Gaithersburg, MD 20899 USA.

The technique is applicable to a broad range of functional packages. Its sensitivity is comparable or better than the sensitivity of standard test techniques that utilize specialized test chips. This technique can also be used to test interconnections in failed IC's, since integrity of the internal circuitry is not required in this test. C1 NIST, Div Polymers, Gaithersburg, MD 20899 USA.

The incorporation of scanning acoustic microscope inspections in reliability tests of molded surface mount components has identified delamination at the mold compound/die interface as the primary cause of electrical failure during temperature cycling. The ability of the acoustic microscope to nondestructively image stress distributions prior to failure would greatly extend the impact of scanning acoustic microscopy on new package development and process control. This may be particularly important for the packaging of devices with fragile low-K (dielectric constant) layers in the device structure. C1 Natl Inst Stand & Technol, Gaithersburg, MD 20899 USA.
