Pseudo-first-order reaction rate constants, k(obs), of PHMs increased in the order CHBrCl2 < CHBr2Cl < CHBr3 < CCl4 < CFBr3 < CBrCl3 < CBr2Cl2. The k(obs) values increased with the exposure time, t(eq), of Fe(II) to suspended iron oxides which was attributed to the rearrangement of initially sorbed Fe(II) species to more reactive surface species with time. At pH 7.2, the k(obs) values of PHMs also increased with the concentration of surface-bound ferrous iron, Fe(II)(sorb), particularly when Fe(II)(tot) was increased to concentrations where surface precipitation becomes likely. At fixed total Fe(II) concentrations, k(obs) values increased exponentially with pH. The highest reactivities were associated with pH conditions where surface precipitation of Fe(II) is expected. Fe(II)(sorb) and pH, however, had opposite effects on the product formation of PHMs. At pH 7.2, the formation of formate from CX4 (X = Cl, Br) increased with Fe(II)(sorb), whereas increasing pH favored the format ion of CHX3. The ratio of halogenated products and formate formed is indicative of the relative importance of initial one- or two-electron-transfer processes, respectively, and was found to depend on the type of iron oxide mineral also. Our data form a basis to assess the importance of chemical reactions in natural attenuation processes of PHMs in environmental systems under iron-reducing conditions.

Initial tests were performed using a small commercially available AA Hg detector operated in series with an optical breadboard version of the D-2 background correction system. Based on encouraging results obtained with that system while using streams of elemental Hg and SO2 (an interfering gas), a compact prototype Hg analyzer for use in a Hg continuous emission monitor (CEM) was built. In laboratory tests performed in the absence of interfering gases, the analyzer could detect 0.5 mug/m(3) or less of elemental Hg, The noise in the D-2 channel of the analyzer was a limiting factor with respect to instrument sensitivity when background-corrected absorbance values were used. Tests with gas streams containing 9-26 mug/m(3) of elemental Hg and 0.02-0.44% SO2 indicated that the D2 background correction approach did a good job at subtracting the large interfering signal due to SO2. However, a correction factor had to be applied to the absorbance readings from the D-2 channel of the analyzer in order to obtain acceptable accuracy for the background-subtracted Hg measurements.

Specifically, the recovery of hydroxide from alkaline media by liquid-liquid extraction can be effected utilizing weak hydroxy acids, as demonstrated for NaOH utilizing a series of lipophilic fluorinated alcohols and alkylated phenols dissolved in 1-octanol. Extraction efficiency follows the expected order of acidity of the hydroxy acids, the phenols being the most efficient extractants among the compounds tested. After extraction, NaOH is effectively recoverable from the organic phase upon contact with water. The weakest hydroxy acids are the most efficiently stripped, NaOH recovery being nearly quantitative in a single contact. In competitive extraction experiments, good selectivity for hydroxide recovery over other anions such as nitrate and chloride was demonstrated. Since the order of extraction favors larger anions, the exceptional preference for hydroxide implies that the extraction occurs by deprotonation of the hydroxy acids in a cation-exchange process. Stripping therefore occurs by hydrolysis to regenerate the neutral hydroxy acid, liberating NaOH to the aqueous phase. Since hydroxide equivalents rather than actual hydroxide ions are transferred to the solvent,the process is termed "pseudo-hydroxide extraction." Hydroxide recovery from a simulant of alkaline nuclear tank waste (Hanford DSSF simulant) was also demonstrated in repeated extraction and stripping cycles.

As each major earthquake adds new surface to the cumulative scarp exposing new material to cosmic-ray bombardment these exposure histories allow the slip history to be constrained. The results show that an earthquake occurred on this fault 2800 +/- 300 yr ago. We infer that this is the seismic event that destroyed ancient Sparta in 464 B. C. Four earlier earthquakes ruptured the Sparta fault in the last 13 ka with similar slip amplitudes of about 2 m and with time intervals ranging from 500 yr to 4500 yr. The observations also confirm that the Sparta scarp is post-glacial, supporting the hypothesis that similar scarps elsewhere in the Mediterranean region have a comparable age. The absence of any event since 464 B. C. could suggest a future event is imminent. However, the irregularity of earthquake time intervals could also be due to changes of loading with important consequences for the mechanics of continental deformation.

By combining the satellite imagery with in situ measurements of water temperature and wind velocity we show that the bloom was triggered by a brief wind event that was sufficient to cause substantial vertical mixing even though the lake was already stratified. We conclude that episodic events can have significant effects on the biological state of large lakes and should be included in biogeochemical process models.

The tuff sample is from a surface outcrop of the Calico Hills formation, which lies below the proposed location for a high-level nuclear waste repository, at Yucca Mountain, NV. The sample is a devitrified tuff composed mainly of zeolites and having clinoptilolite (approximately 70%), mordenite, and opal-CT as major constituents. The sample is an air dry, intact core sample. QNS measurements were made in the range 200 K to 423 K. Rotational motion of adsorbed water is easily observable and translational motion is observable at higher temperatures. The tuff data are analyzed to determine the rotational diffusion coefficient and the translational diffusion coefficient. The results yield a translational diffusion coefficient in the tuff that is significantly lower than that of bulk water but higher than for water in montmorillonite or vermiculite clays.

Since the Holocene archaeomagnetic record also contains features consistent with a 7000- year cycle, a likely explanation is that the C-14 data are recording modulation of cosmogenic isotope production due to variations in geomagnetic shielding. A longer-term Cl-36 record contains evidence for similar periodicities, suggesting that these geomagnetic variations may have been present for tens of millennia.

Our results indicate that the maximum ionization efficiency of thorium, a notoriously difficult element to ionize thermally, in the present TIC-TOFMS system is about 1-3%. This represents a 10-30x enhancement of the typical Th sample utilization for conventional, Re filament-based, thermal ionization mass spectrometry sources. Thorium samples were small (0.075-25 ng), therefore, analytical blanks for Th in the tungsten TIC were also measured and subtracted from the total Th ion signal arriving at the detector. Prominent peaks that correspond to multiply-charged (2(+) and 3(+)) tungsten ions are always evident in high-temperature (>2400degreesC) spectra. Furthermore, TIC-TOFMS spectra also contained peaks corresponding to elements with ionization potentials in excess of 8 eV, such as beryllium. The presence of multiply-charged tungsten peaks, and beryllium peaks, are indicative of significant ionization via non-thermal processes, such as electron impact, in or near the TIC.

The CID rate correction enables the correlation of bond dissociation energy with CID rate, allowing quantitative determinations of bond dissociation energies for lanthanide metal monoxide ions. For bond dissociation energies in the range of 567-849 kJ mol(-1), mass corrected rates range from 50 to 120 s(-1). The calibration sensitivity is equivalent to 5 kJ mol(-1) s(-1), and the measurement precision is similar to25 kJ mol(-1). Bond energy determinations are found to agree with the average values reported for lanthanide oxide ions. (C) 2002 Elsevier Science B.V. All rights reserved.

The drift time to the ion detector can used to determine kinetic ion energies. A very wide range of cathode materials have been used. It has been found that the kinetic ion energy is higher at the beginning of each discharge and approximately constant after 150 mus. The kinetic energy is correlated with the arc voltage and the cohesive energy of the cathode material. The ion erosion rate is in inverse relation to the cohesive energy, enhancing the effect that the power input per plasma particle correlates with the cohesive energy of the cathode material. The influence of three magnetic field configurations on the kinetic energy has been investigated. Generally, a magnetic field increases the plasma impedance, arc burning voltage, and kinetic ion energy. However, if the plasma is produced in a region of low field strength and streaming into a region of higher field strength, the velocity may decrease due to the magnetic mirror effect. A magnetic field can increase the plasma temperature but may reduce the density gradients by preventing free expansion into the vacuum. Therefore, depending on the configuration, a magnetic field may increase or decrease the kinetic energy of ions. (C) 2002 American Institute of Physics.

The enthalpies of the phase change to high temperature (HT) pseudo-cubic Mg2NiH4 and of hydrogen absorption by Mg2Ni are calculated and compared with experimental values. LT Mg2NiH4 is found to be a semiconductor with an indirect band gap of 1.4 eV. The optical dielectric function of LT Mg2NiH4 differs somewhat from that of the HT phase.

On the atomic scale, scanning transmission electron microscopy observations reveal the existence of an Sb-Mn-Sb structure at the interface between the MnSi layer and the Si substrate. The formation of the MnSb plays an important role for the improvement of crystalline quality of the silicide layer, acting both as a surfactant and as a compliant substrate for stress relief.

The obtained results are analyzed in terms of the hopping model of TSL in disordered organic materials. It is shown that the experimentally obtained TSL curve can be fitted on the basis of a double-peak Gaussian density-of-states distribution. The upper peak is associated with intrinsic localized states while the lower one can be ascribed to aggregates. The latter assignment is also supported by measurements of steady-state and time-resolved photoluminescence in DOO-PPV films and solutions. Possible mechanisms of charge carrier photogeneration in DOO-PPV are discussed. (C) 2002 American Institute of Physics. C1 Natl Acad Sci Ukraine, Inst Phys, UA-252650 Kiev, Ukraine.

The c(0) lattice parameter followed Vegard's law using c(0)=0.5185 nm for GaN and c(0)=0.569 nm for InN. Band gap measurements by photocurrent spectroscopy fit well with data published by one other research group, with the combined set being described by the equation E-g=3.41-7.31x+14.99x(2) for 0less than or equal toxless than or equal to0.15. Photoluminescence measurements with a pulsed nitrogen laser showed a peak well below the measured band gap, as well as significant luminescence above the measured band gap. The above-gap luminescence appears to be due to band filling by the high intensity laser pulses. (C) 2002 American Institute of Physics. C1 Colorado Sch Mines, Dept Phys, Golden, CO 80401 USA.

With decreasing T, and depending on H, the alloy exhibits superparamagnetic, field-induced ferromagnetic, and spin-glass behavior. The temperature-dependence of the magnetic entropy change, DeltaS=S(H)-S(H=0), exhibits extreme values: a minimum at the superparamagnetic-to-ferromagnetic transition and a maximum at the ferromagnetic-to-spin-glass transition. At 80 K, and for H=50 kOe, the entropy change is -0.029 k(B) per Fe atom in the alloy. This value compares favorably with that measured in other crystalline and amorphous Fe-based alloys, but it is lower than that measured in some rare-earth elements.

EDESI-MS maps show a simple collision-induced dissociation (CID) process for Ru3Co(CO)(n)(-) by stripping CO down to the metal core. For the doubly charged species, two competing CID channels were observed, viz. loss of neutral CO and loss of CO+e(-). It was found that the parent dianions first lose neutral CO down to n=9, producing a series of dianions, Ru6C(CO)(n)(2-) (n=9-16) and Ru-6(CO)(n)(2-) (n=9-18). For n<9, the dianions become electronically unstable against autodetachment, and singly charged anions, Ru6C(CO)(n)(-) and Ru-6(CO)(n)(-) (n=0-9), were observed. The PES spectra of the dianions show the electron binding energies decrease monotonically as n decreases and become similar to0.0 eV for n=9, in exact agreement with the CID patterns that reflect the electronic instability of the doubly charged metal complexes with n<9. All of the PES spectra show congested features, indicating very high density of low-lying electronic states for the transition metal carbonyl clusters. The electron binding energies of Ru3Co(CO)(n)(-) are similar for n=4-13, but decrease sharply from n=4 to 0. The intramolecular Coulomb repulsion in the dianions was observed to increase with loss of CO, ranging from similar to1.8 eV for Ru6C(CO)(16)(2-) to similar to2.4 eV for Ru6C(CO)(9)(2-).

MARS facilitate long-range chromatin remodeling required for enhancer activity and have been found closely linked to several lymphoid enhancers. Within the human CD8 gene complex, we identified six DNase HS clusters, four strong MARs, and several weaker MARs. Three of the strong MARS were closely linked to two tissue-specific DNase HS clusters (III and IV) at the 3' end of the CD8B gene. To further establish the importance of this region, we obtained 19 kb of sequence and screened for potential binding sites for the MAR-binding protein, SATB1, and for GATA-3, both of which are critical for T cell development. By gel shift analysis we identified two strong SATB1 binding sites, located 4.5 kb apart, in strong MARS. We also detected strong GATA-3 binding to an oligonucleotide containing two GATA-3 motifs located at an HS site in cluster IV. This clustering of DNase HS sites and MARs capable of binding SATB1 and GATA-3 at the 3' end of the CD8B gene suggests that this region is an epigenetic regulator of CD8 expression.

The time dependent emitted current was measured while the laser diode was TTL-amplitude modulated at frequencies from 10 Hz to 50 kHz. It was found that below 100 Hz, the rise and fall times of the field emitted current ranged from 2 to 3 ms, but beginning at 300 Hz, the rise and fall times become shorter as the frequency is increased. The incremental change in the total emitted current is greater at 5 kHz than at any of the other frequencies. Since the only parameter changed was the modulation frequency, we conclude that these effects are not consistent with the assumptions from photofield studies that (1) the increase in the total current is mainly thermal and therefore slow, (2) the current increase is small, and (3) the effect is negligible at the red end of the spectrum. From the carried out experiments, we conclude that the current increase is not caused by tip heating, but rather, they show the significance of the circuit parameters of the field emitter tube itself.

Lower stress relief temperatures and slower cooling of the material from the stress relief temperature to room temperature both reduce the copper level in the matrix and should lead to less embrittlement during service in a nuclear reactor.

Molybdenum was found to partition to the lenticular Ni-2(Mo,Cr) precipitates whereas iron, aluminum, silicon, manganese and nickel were found to partition to the gamma matrix. Chromium was not found to partition significantly between the phases. Atom probe tomography and energy-filtered transmission electron microscopy core-loss images revealed boron, molybdenum, chromium, phosphorus and carbon segregation to the grain boundaries. Despite the size of the precipitates being larger after a two-step heat treatment of 16 h at 704 degreesC + 16 h at 650 degreesC compared to a one-step heat treatment of 48 h at 650 degreesC, no significant differences were found in the mechanical properties or the compositions of the phases.

SCATTERING; EVENT GENERATOR; LOW Q(2); PHOTOPRODUCTION; CONSTRUCTION; DESIGN AB The photon-proton total cross section has been measured in the process e(+)p --> e(+)gammap --> e(+)X with the ZEUS detector at HERA. Events were collected with photon virtuality Q(2) < 0.02 GeV2 and average gammap center-of-mass energy W-gammap = 209 GeV in a dedicated run, designed to control systematic effects, with an integrated luminosity of 49 nb(-1). The measured total cross section is sigma(tot)(gammap) = 174 +/- 1 (stat.) +/- 13 (syst.) mub. The energy dependence of the cross section is compatible with parameterizations of high-energy p (p) over bar and p data. (C) 2002 Elsevier Science B.V. All rights reserved.

I. mechanistic insights SO NUCLEIC ACIDS RESEARCH LA English DT Article ID HUMAN APURINIC/APYRIMIDINIC ENDONUCLEASE; POLYMERASE-BETA; SUBSTRATE-SPECIFICITY; MATHEMATICAL-MODEL; ABASIC SITE; ACTIVE-SITE; PROTEIN; GLYCOSYLASE; PATHWAY; DAMAGE AB Base excision repair (BER) is a multistep process involving the sequential activity of several proteins that cope with spontaneous and environmentally induced mutagenic and cytotoxic DNA damage. Quantitative kinetic data on single proteins of BER have been used here to develop a mathematical model of the BER pathway. This model was then employed to evaluate mechanistic issues and to determine the sensitivity of pathway throughput to altered enzyme kinetics. Notably, the model predicts considerably less pathway throughput than observed in experimental in vitro assays. This finding, in combination with the effects of pathway cooperativity on model throughput, supports the hypothesis of cooperation during abasic site repair and between the apurinic/apyrimidinic (AP) endonuclease, Ape1, and the 8-oxoguanine DNA glycosylase, Ogg1. The quantitative model also predicts that for 8-oxoguanine and hydrolytic AP site damage, short-patch Polbeta-mediated BER dominates, with minimal switching to the long-patch subpathway. Sensitivity analysis of the model indicates that the Polbeta-catalyzed reactions have the most control over pathway throughput, although other BER reactions contribute to pathway efficiency as well. The studies within represent a first step in a developing effort to create a predictive model for BER cellular capacity.

Using a linear quadrupole to manipulate the particles in space, we are able to take advantage of a modified surface structure in the blend particle to actively assemble particles in programmable two- or three-dimensional architectures. Strong resonance features in fluorescence are observed near the intersection of linked spheres that cannot be interpreted with a two-dimensional (equatorial plane) model. Three-dimensional ray optics calculations show long-lived periodic trajectories that propagate in great circles linked at an angle with respect to the plane containing the sphere centers.

The singly resonant OPO is pumped by a single-mode, 10-W, continuous-wave Nd:YAG laser and consists of a bow-tie ring cavity with a fan-out periodically poled lithium niobate crystal and a low-finesse intracavity air-spaced etalon. The single-frequency idler output can be continuously tuned over 24 GHz with 700-mW power by tuning of the pump laser. The tuning was demonstrated by recording of an absorption line of ethane with photoacoustic spectroscopy. (C) 2002 Optical Society of America. C1 Univ Nijmegen, NL-6525 ED Nijmegen, Netherlands.

These clusters, all possessing 40 valence electrons, were expected to be magic numbers with I-h-X@Al-12 structures, closed electron shells, and large energy gaps.

Results show a nonuniform composition distribution in the quantum dots with the highest Ge content at the dot center. The average Ge content in the quantum dots is much higher than in the wetting layer. The quantum dot/substrate interface has been moved to the substrate side.

We study the effect of interfacial atomic mixing on the electronic structure of such superlattices, including electron and hole energies and wave function localization, interband transition energies, and dipole matrix elements. We combine an empirical pseudopotential method for describing the electronic structure with two different structural models of interfacial disorder. First, we use the "single-layer disorder" model and change in a continous way the composition of the interfacial bonds. Second, we study interfacial atomic segregation using a layer-by-layer kinetic model of molecular beam epitaxy growth, fit to the observed scanning tunneling microscopy segregation profiles. The growth model provides a detailed structural model of segregated InAs/GaSb superlattices with atomic resolution. The application of the empirical pseudopotential method to such structures reveals remarkable electronic consequences of segregation, among them a large blueshift of the band gap. This result explains the surprising gap increase with growth temperature observed for similar structures. In particular we find that (i) superlattices with only In-Sb interfacial bonds have lower band gaps (by 50 meV) than superlattices with only Ga-As interfacial bonds. (ii) Heavy-hole-to-electron transition energies increase with the number of Ga-As interfacial bonds more than light-hole-to-electron transition energies. (iii) The heavy-hole hh1 wave functions show a strong localization on the In-Sb interfacial bonds. The heavy-hole wave functions have very different amplitudes on the Ga-As interface and on the In-Sb interface. (iv) Sb segregates at InAs-on-GaSb growth, whereas As and In segregate at GaSb-on-InAs growth, but Ga does not segregate. (v) The segregation of Sb and In induces a blueshift in the band gap. (vi) There is an in-plane polarization anisotropy due to the low symmetry of the no-common-atom InAs/GaSb superlattice. This anisotropy is reduced by interfacial segregation.

Hybrid density functionals which combine a portion of "exact" Fock exchange with conventional local density approximation (LDA) or generalized gradient approximation (GGA) functionals remedy a number of serious inconsistencies with the traditional LDA or GGA descriptions of this prototypical "Mott" insulator. For example, the hybrid B3LYP functional (which mixes similar to20% Fock exchange with GGA functionals) introduces a significant insulating gap and yields antiferromagnetic Heisenberg coupling constants between Ni sites (J(2)) in semiquantitative agreement with experiment. Closer inspection shows that while the B3LYP orbital band gap is in excellent agreement with experiment, the magnitude of the antiferromagnetic coupling is overestimated by slightly more than 50%. This has led us to examine a simplified model which combines Fock exchange with the LDA exchange and correlation functionals. This combination allows us to study the magnitude and nature of the band gap, the magnitude of the unpaired spin densities in the different magnetic phases, and the two most important magnetic coupling constants as a function of the fraction of Fock exchange included. It is concluded that similar to35% Fock exchange gives a reasonably balanced description of all properties, including structural parameters, magnetic form factors, the antiferromagnetic Ni-Ni exchange constant, and the character and magnitude of the band gap.

The quadrupole (and higher order nondipole) contributions to the photoelectron emission matrix element differ for these two beams due to their different wave vectors. By monitoring the angle-resolved photoelectron yield as a function of photon energy near the (11-1) Bragg back-reflection condition of crystalline Ge, we measure the contribution of nondipole effects to Ge 3p, Ge 3d, and Ge valence-band (4s and 4p) XSW photoelectron emission. Significant changes due to nondipole emission are measured in both the apparent amplitude and phase of the Ge structure factor relative to the true Ge atomic distribution, and compared to theory.

The Li2Mo6Se6 crystal is composed of molecular chains, which can be separated from one another to form individual nanowires approximately 3 Angstrom in diameter. In this study we consider three systems: the quasi-one-dimensional bulk crystal Li2Mo6Se6, one isolated MoSe nanowire, and one isolated MoSe nanowire with Li adsorbates. The equilibrium structures and the electronic structures of the three systems were calculated and compared to each other. The calculated density of states of an isolated MoSe wire is compared with experimental tunneling spectroscopy measurements of the local density of states. The binding energy of a Li atom to an isolated wire was calculated and the effects of Li adsorption are discussed. In addition, the calculated value for the ideal tensile strength of a single MoSe nanowire is presented and compared with estimated values for carbon nanotubes.

The polarization direction of the incident photon beam was varied with respect to the crystal axes to obtain strong angular dependence in both the absorption and emission data. Using both energy and angular selection, we obtain local partial densities of states information for each oxygen site, which are compared directly with theoretical results. This technique should be very useful in studies of asymmetric materials such as high-T-c superconducting materials with in-plane and out-of-plane oxygen sites.

Different sulfur coverages (0.25, 0.33, and 1 ML) and several adsorption geometries are considered. It is found that, for atomic sulfur, the S-Pt bond is weakened with the increase of sulfur coverage and the most stable adsorption site changes from fcc-hollow site to atop site. The S 2p core levels shift to higher binding energy with the increase of S coverage. The Pt 4f core levels are stabilized upon interaction with the S adsorbate, and yet the Pt to S charge transfer is not substantial in many cases. S adsorption induces significant decreases in the density of Pt 5d states near the Fermi energy. For the case of S-2 adsorption, the S-S bond length is 2.1 Angstrom with one atom near an atop position and the other on a mixed bridge-hollow site. The adsorption energy is close to 44 kcal/mol.

By rotating the polarization direction, we see a dramatic change in the absorption spectra at the oxygen K edge. Our theory identifies the detailed composition of the spectra and predicts a correct energy ordering of the orbitals of three inequivalent oxygen atoms. Because different orbitals dominate absorption spectra at different energies and angles, one can excite at a specific site and "orbital." In contrast, absorption at the vanadium L edge does not show large changes when varying the polarization direction. The reason for this is that different excitation channels (involving different initial states for the excited electron) overlap in energy and vary in compensating ways, obscuring each channel's sensitive polarization dependence.

Much effort has been expended looking for possible systematic origins of the residuals, but none has been found.

On the contrary, one expects bulk curvature terms that violate the SO(3,1) isometry at early epochs, leading to a violation of Lorentz invariance on our brane. Demanding that the Lorentz noninvariant terms are small leads to a new "flatness" problem, not solved by the usual formulation of inflation for a class of braneworld solutions. Furthermore, unlike in four dimensions, the Lorentz violations induced from the bulk curvature cannot always be removed as the infrared cutoff is taken arbitrarily large. This means that the equivalence principle in higher dimensions does not guarantee the equivalence principle in dimensionally reduced theories. Near-future experiments are expected to severely constrain these Lorentz-violating "signatures" of extra dimensions. C1 Univ Michigan, Randall Lab Phys, Ann Arbor, MI 48109 USA.

These models have a rich dynamical structure resulting from the interaction of the fields and their associated fluctuations. We present a formalism to study the nonequilibrium dynamics of coupled scalar fields. This formalism solves the problem of renormalizing interacting models in a transparent way using dimensional regularization. The evolution is generated by a renormalized effective Lagrangian which incorporates the dynamics of the mean fields and their associated fluctuations at one-loop order. We apply our method to two problems of physical interest: (i) a simple two-field model which exemplifies applications to reheating in inflation, and (ii) a supersymmetric hybrid inflation model. This second case is interesting because inflation terminates via a smooth phase transition which gives rise to a spinodal instability in one of the fields. We study the evolution of the zero mode of the fields and the energy density transfer to the fluctuations from the mean fields. We conclude that back reaction effects can be significant over a wide parameter range. In particular for the supersymmetric hybrid model we find that particle production can be suppressed due to these effects. C1 Univ Sussex, Ctr Theoret Phys, Brighton BN1 9QH, E Sussex, England.

We establish the rules for instanton calculations in 5D theories on the circle, and use them for an explicit one-instanton calculation in a supersymmetric gauge theory. The results are then compared to the known exact Seiberg-Witten type solution for this theory, confirming the validity both of the exact results and of the rules for instanton calculus for extra dimensions introduced here. Next we consider the nonperturbative results from the perspective of deconstructed extra dimensions. We show that the nonperturbative results of the deconstructed theory do indeed reproduce the known results for the continuum extra dimensional theory, thus providing the first nonperturbative evidence in favor of deconstruction. This way deconstruction also allows us to make exact predictions in higher dimensional theories which agree with earlier results, and helps to clarify the interpretation of 5D instantons.

The matter content of the model is assumed to be comoving dust plus a positive cosmological constant. The model presents a critical point of saddle-center-center type in the finite region of phase space. This critical point engenders in the phase space dynamics the topology of stable and unstable four dimensional tubes RxS(3), where R is a saddle direction and S-3 is the manifold of unstable periodic orbits in the center-center sector. A general characteristic of the dynamical flow is an oscillatory mode about orbits of an invariant plane of the dynamics which contains the critical point and a Friedmann-Robertson-Walker (FRW) singularity. We show that a pair of tubes (one stable, one unstable) emerging from the neighborhood of the critical point towards the FRW singularity have homoclinic transversal crossings. The homoclinic intersection manifold has topology RxS(2) and is constituted of homoclinic orbits which are biasymptotic to the S-3 center-center manifold. This is an invariant signature of chaos in the model, and produces chaotic sets in phase space. The model also presents an asymptotic de Sitter attractor at infinity and initial conditions sets are shown to have fractal basin boundaries connected to the escape into the de Sitter configuration (escape into inflation), characterizing the critical point as a chaotic scatterer.

In this scenario, the non-calculable correction to gauge unification from unknown ultraviolet physics is naturally suppressed by the large volume of the extra dimension, and the threshold correction is dominated by a calculable contribution from Kaluza-Klein towers that gives the values for sin(2)theta(w) and alpha(s) in good agreement with low-energy data. The threshold correction is reliably estimated despite the fact that the theory is strongly coupled at the cutoff scale. A realistic 5D supersymmetric SU(5) model is presented as an example, where rapid d=6 proton decay is avoided by putting the first generation matter in the 5D bulk.

Bottom and charmed hadrons were tagged via their semileptonic decays. Both the electron and muon analyses take advantage of new multivariate techniques to increase the analyzing power. Based on the 1993-1998 SLD sample of 550 000 Z(0) decays produced with highly polarized electron beams, we measure A(b) = 0.919 +/-0.030(sta) +/- 0.024(syst) , and A(c) = 0.583 +/- 0.055(stat) +/- 0.055(syst).

LETTERS LA English DT Article ID HADRONIC DIFFRACTION; RAPIDITY GAPS; POMERON; COLLISIONS; HERA AB We report a measurement of the diffractive structure function F-jj(D) of the antiproton obtained from a study of dijet events produced in association with a leading antiproton in (p) over barp collisions at roots = 630 GeV at the Fermilab Tevatron. The ratio of F-jj(D) at roots = 630 GeV to F-jj(D) obtained from a similar measurement at roots = 1800 GeV is compared with expectations from QCD factorization and other theoretical predictions. We also report a measurement of the xi (x-Pomeron) and beta (x of parton in Pomeron) dependence of F-jj(D) at roots = 1800 GeV . In the region 0.035 < ξ < 0.095 , \t\ < 1 GeV2 , and β < 0.5 , F-jj(D)(beta, xi) is found to be of the form beta(-1.0+/-0.1) xi(-0.9+/-0. 1) , which obeys beta-xi factorization.

The increase in surface chemical potential induces atoms to flow into the grain boundary, creating a compressive stress in the film. We develop kinetic equations to describe the stress evolution and dependence on growth parameters. The model is used to explain measurements of relaxation when growth is terminated and the dependence of the steady-state stress on growth rate. C1 Brown Univ, Div Engn, Providence, RI 02912 USA.

The transverse component of the wake field excited by the short electron bunch focuses the bunch, which experiences multiple betatron oscillations as the plasma density is increased. The spot-size variations are observed using optical transition radiation and Cherenkov radiation. In this regime, the behavior of the spot size as a function of the plasma density is well described by a simple beam-envelope model. Dynamic changes of the beam envelope are observed by time resolving the Cherenkov light. C1 Univ So Calif, Los Angeles, CA 90089 USA.

For the first time differential lifetime measurements free from common systematic errors for over 15 different nuclei (>30 rotational bands in various isotopes of Ce, Pr, Nd, Pm, and Sm) have been extracted at high spin within a single experiment. This comprehensive study establishes the effective single-particle transition quadrupole moments in the A similar to 135 light rare-earth region. Detailed comparisons are made with theoretical calculations using the self-consistent cranked mean-field theory which convincingly demonstrates the validity of the additivity of single-particle quadrupole moments in this mass region.

Along the GammaK and GammaM directions, we observed three distinct dispersive features approaching the Fermi energy. These can be assigned to the theoretically predicted sigma (B 2p(x,y) ) and pi (B 2p(z)) bands. In addition, a small parabolic-like band is detected around the Gamma point, which can be attributed to a surface-derived state. The overall agreement between our results and the band calculations suggests that the electronic structure of MgB2 is of a conventional nature, thus implying that electron correlations are weak and may be of little importance to superconductivity in this system.

To accomplish this, energy is transferred from a long drive pulse at frequency omega(pump) to an intense seed pulse at frequency omega(seed), with a Langmuir plasma wave at frequency omega(p) mediating the transfer; the frequencies are chosen to satisfy the resonant condition omega(p) = omega(pump)-omega(seed). Diffraction of the pulses limits the interaction length in a uniform plasma, and hence the energy transfer between the pulses. However in a parabolic plasma density channel it is shown, through two-dimensional particle-in-cell simulations, that such a plasma channel can be used to guide both the amplified and drive pulses over an interaction distance much greater than a diffraction length. The seed pulse is amplified by a factor of more than 200 in energy for pulses whose widths are matched to the channel size, and achieve a peak intensity of more than 6 x 10(17) W/cm(2). Unmatched pump pulses are seen to generate much smaller gain. (C) 2002 Elsevier Science B.V. All rights reserved. C1 Univ Calif Berkeley, Berkeley, CA 94720 USA.

We find that both the wake amplitude and the accelerating efficiency (transformer ratio) can be maximized by properly shaping the longitudinal profile of the driving laser pulse. The corresponding family of laser pulse shapes is derived in the nonlinear regime of laser-plasma interaction. Such shapes provide theoretical upper limit on the magnitude of the wakefield and efficiency by allowing for uniform photon deceleration inside the laser pulse. We also construct realistic optimal pulse shapes that can be produced in finite-bandwidth laser systems. (C) 2002 Elsevier Science B.V. All rights reserved.

The mechanism of arsenite-induced carcinogenesis is unknown. Arsenite is known to disrupt mitosis and to delay transit through M phase in normal diploid fibroblasts. SV40-transformed human fibroblasts were observed to be hypersensitive to the cytotoxic and cytostatic effects of NaASO(2) compared with normal diploid fibroblasts in concentration-response experiments. Five to 20 muM NaAsO2 induced cytostasis in cycling normal diploid fibroblasts but not overt lethality in quiescent normal diploid fibroblasts. High concentrations of arsenite were overtly lethal in both cycling and quiescent cells. The IC50 for cycling SV40-transformed fibroblasts was 3.8 and 4.8 muM for the SV40-transformed lines GM4429 and GM0637, respectively, whereas, in cycling normal diploid fibroblasts (GM0024), the IC50 was 24.7 muM. Microscopic examination of NaAsO2-treated SV40-transformed fibroblasts suggested a concentration-dependent accumulation of cells in mitosis undergoing apoptosis. Treatment of SV40-transformed fibroblasts with 0-10 muM NaAsO2 caused a concentration-de pendent inhibition of cell proliferation, accumulation of cells having G2/M DNA contents, and increases in the mitotic index. Phase microscopy, annexin V binding, and electron microscopy demonstrated that arrested mitotic cells underwent apoptosis. These results indicate that SV40-transformation sensitizes cells to arsenite-induced mitotic arrest and induction of apoptosis in the mitotic cells. (C) 2002 Elsevier Science (USA).

In response to ionizing radiation (111), ATM, the gene product mutated in ataxia telangiectasia, stabilizes and activates p53 through phosphorylation of Ser(15) and (indirectly) Ser(20). Here we show that phosphorylation of p53 on Ser(46), a residue important for p53 apoptotic activity, as well as on Ser(9), in response to IR also is dependent on the ATM protein kinase. IR-induced phosphorylation at Ser(46) was inhibited by wortmannin, a phosphatidylinositol 3-kinase inhibitor, but not PD169316, a p38 MAPK inhibitor. p53 C-terminal acetylation at Lys(320) and Lys(382), which may stabilize p53 and activate sequence-specific DNA binding, required Ser15 phosphorylation by ATM and was enhanced by phosphorylation at nearby residues including Ser(6), Ser(9), and Thr(18). These observations, together with the proposed role of Ser(46) phosphorylation in mediating apoptosis, suggest that ATM is involved in the initiation of p53-dependent apoptosis after IR in human lymphoblastoid cells.

These measurements were carried out using only the racemic mixture. The experimental data were fitted to four different isotherm models: Langmuir, BiLangmuir, Langmuir-Freundlich and Toth. The BiLangmuir and the Langmuir-Freundlich models accounted best for the competitive adsorption data. An excellent agreement between the experimental and the calculated overloaded band profiles for various samples of racemic mixture was obtained when the equilibrium dispersive model of chromatography was used together with the BiLangmuir competitive isotherm. The isotherm parameters measured under competitive conditions were used to calculate the overloaded band profiles of large samples of the pure S- and R-enantiomers. too. A satisfactory agreement between the experimental and calculated band profiles was observed when using in the computation the corresponding single component BiLangmuir isotherm derived from the binary isotherm previously determined. Thus only data derived from the racemic mixture are required for computer optimization of the preparative chromatography separation of the enantiomers. (C) 2002 Elsevier Science B.V.

The VAT-monomer exhibits the tripartite domain architecture typical for type 11 AAA-ATPases: N-D1-D2, whereby N is the substrate binding N-terminal domain preceding domains D1 and D2, both containing AAA-modules. Recent 3-D reconstructions of VAT and p97 as obtained by electron microscopy suffer from weakly represented N-domains, probably a consequence of their flexible linkage to the hexameric core. Here we used electron cryo-microscopy and 3-D reconstruction of single particles in order to generate a 3-D model of VAT at 2.3 nm resolution. The hexameric core of the VAT-complex (diameter 13.2 nm, height 8.4 nm) encloses a central cavity and the substrate-binding N-domains are clearly arranged in the upper periphery. Comparison with the p97 3-D reconstruction and the recently determined crystal structure of p97-N-D1 suggests a tail-to-tail arrangement of D1 and D2 in VAT. (C) 2002 Elsevier Science Ltd.

Reactions were monitored in situ by static FT-IR spectroscopy, and assignments are based on experiments with CD2=O and CD3OD. Most efficient was the reaction with H2O2, as indicated by the fact that Ho2CH,OH was formed at the exclusion of CH2(OH)(2) and POCH2OH when adsorbing formaldehyde onto a sieve loaded with H2O2 and H2O. Methoxymethanol, methanediol, and POCH2OH were stable at 250 K but dissociated above 0degreesC under release of formaldehyde. Hydromethyl hydroperoxide disproportionates to formic acid and water. Under 355 nm irradiation in a FeAlPO4 sieve, HO2CH2OH was found to undergo efficient photofragmentation.

Measurements using the rapid-scan method revealed that the final products, HCO2-...Fe and H2O, emerge with a rise time of 4 s (250 K) by decomposition of the two-electron-transfer intermediate, HO2CH2OH. Intermediacy of hydroxymethylhydroperoxide was established by direct detection by step-scan FT-IR spectroscopy on the 500 microsecond time scale and by monitoring of its photodissociation products HCO2H + H2O on the millisecond and second time scale. Formaldehyde was observed as minor two-electron oxidation product. The fast rise of the HO2CH2OH intermediate strongly suggests that it is formed by direct coupling of HOO and CH2OH radicals. This constitutes the most conclusive evidence yet for the formation of a hydroperoxy radical and hydroxymethyl radical as the primary one-electron-transfer products of the reaction of CH3OH and O-2 at LMCT-excited framework Fe centers.

The film consists of a tilted array of porous nanoscale crystalline filaments. Surprisingly, the individual filaments exhibit a high degree of crystallographic order with respect to each other. These films have chemical binding sites analogous to those on MgO(100). However, the fraction of chemically active, high energy binding sites is greatly enhanced on the nanoporous film. This unique collection of properties makes these materials attractive candidates for chemical applications such as sensors and heterogeneous catalysts.

The transition made by underdoped high-transition-temperature (high-T-c) superconductors is unusual, in that it is not a mean-field transition as seen in other superconductors. Rather, there is a region in the phase diagram above the superconducting transition temperature T-c (where phase coherence and superconductivity begin) but below a characteristic temperature T* where a 'pseudogap' appears in the spectrum of electronic excitations(1,2). It is therefore important to establish if T* is just a cross-over temperature arising from fluctuations in the order parameter that will establish superconductivity at T-c (refs 3, 4), or if it marks a phase transition where symmetry is spontaneously broken(5-10). Here we report that, for a material in the pseudogap state, left-circularly polarized photons give a different photocurrent from right-circularly polarized photons. This shows that time-reversal symmetry is spontaneously broken(11) below T*, which therefore corresponds to a phase transition. C1 Univ Illinois, Dept Phys, Chicago, IL 60607 USA.

As the iteration number increases, the feedforward controller decreases the tracking error. Numerical simulations demonstrate that inclusion of the feedforward controller significantly improves the control system performance over its performance with just the feedback controller.

Final particle spectra are obtained using two hadronization models; the Lund string fragmentation and independent fragmentation models. Recent, preliminary pi(0) transverse momentum distributions from central Au + Au collisions at RHIC are reproduced using gluon-gluon scattering cross sections of 5-12 mb, depending upon the hadronization model. Comparisons with the HIJING jet quenching algorithm are made. (C) 2002 Elsevier Science B.V. All rights reserved. C1 Brookhaven Natl Lab, RIKEN BNL Res Ctr, Upton, NY 11973 USA.

We analyzed the nucleotide sequence of HIV-1 RNA in plasma samples from 141 children enrolled into PACTG 377, a comparative study of several antiretroviral therapy regimens. Phylogenetic analysis revealed that two children, both born in the United States, were infected with non-B subtypes that are most commonly found in Africa: one with subtype D and the other with circulating recombinant form CRF02, an A/G recombinant lineage. Viral load assays performed to monitor treatment response underestimated the levels of HIV-1 RNA in the child with the A/G recombinant. These cases demonstrate mother-to-child transmission of non-B subtypes of HIV-1 in the United States. Non-B subtypes should be considered in the management of HIV-1-infected pregnant women and children to optimize strategies to prevent and treat pediatric HIV-1 infection.

Only 20 patterns of representations are found to occur. Accomodation of the minimal supersymmetric standard model (MSSM) spectrum is addressed. States beyond those contained in the MSSM and nonstandard hypercharge normalization are shown to be generic, though some models do allow for the usual hypercharge normalization found in SU(5) embeddings of the standard model gauge group. The minimum value of the hypercharge normalization consistent with accommodation of the MSSM is determined for each model. In some cases, the normalization can be smaller than that corresponding to an SU(5) embedding of the standard model gauge group, similar to what has been found in free fermionic models. Bizarre hypercharges typically occur for exotic states, allowing for matter which does not occur in the decomposition of SU(5) representations-a result which has been noted many times before in four-dimensional string models. Only one of the 20 patterns of representations, comprising seven of the 175 models, is found lobe without an anomalous U(1). The sizes of nonvanishing vacuum expectation values induced by the anomalous U(I) are studied. It is found that large radius moduli stabilization may lead to the breakdown of sigma-model perturbativity. Various quantities of interest in effective supergravity model building are tabulated for the set of 175 models. In particular, it is found that string moduli masses appear to be generically quite near the gravitino mass. String scale gauge coupling unification is shown to be possible, albeit contrived, in an example model. The intermediate scales of exotic particles are estimated and the degree of fine-tuning is studied. (C) 2002 Elsevier Science (USA). C1 Univ Calif Berkeley, Dept Phys, Berkeley, CA 94720 USA.

It was found that a monolayer of CO prevented the adsorption of ethylene on the Pt(1 1 1) surface in the presence of high pressure ethylene (up to 35 Torr). In contrast. CO can adsorb on the ethylene pretreated Pt(1 1 1) surface by increasing the CO pressure. However, the coadsorbed ethylidyne molecules weakened CO bonding, which was evidenced by the red-shift in the vibrational frequency. In the presence of high pressure CO (>0.1 Torr) the catalytic ethylene hydrogenation was poisoned due to the site blocking effect of CO adsorption. No catalytic reactivity was observed at temperatures lower than the CO desorption temperature (400 K). The measured apparent activation energy of the CO poisoned ethylene hydrogenation reaction was about 20.5 kcal/mole. (C) 2002 Elsevier Science B.V. All rights reserved.

We show that the strength of this conclusion depends upon the nature of the dark energy causing the present acceleration. Only for a cosmological constant is the SNe evidence definitive. Using a new test which is independent of the contents of the universe, we show that the SN data favor recent acceleration ( z < 0.5) and past deceleration ( z > 0.5).

Most of these stars are within 1.degrees26 of the celestial equator. We present color-magnitude diagrams (CMDs) for stars in two previously discovered, tidally disrupted structures. The CMDs and turnoff colors are consistent with those of the Sagittarius dwarf galaxy, as had been predicted. In one direction, we are even able to detect a clump of red stars, similar to that of the Sagittarius dwarf, from stars spread across 110 deg(2) of sky. Focusing on stars with the colors of F turnoff objects, we identify at least five additional overdensities of stars. Four of these may be pieces of the same halo structure, which would cover a region of the sky at least 40 in diameter, at a distance of 11 kpc from the Sun (18 kpc from the center of the Galaxy). The turnoff is significantly bluer than that of thick-disk stars, yet the stars lie closer to the Galactic plane than a power-law spheroid predicts. We suggest two models to explain this new structure. One possibility is that this new structure could be a new dwarf satellite of the Milky Way, hidden in the Galactic plane and in the process of being tidally disrupted. The other possibility is that it could be part of a disklike distribution of stars which is metal-poor, with a scale height of approximately 2 kpc and a scale length of approximately 10 kpc. The fifth overdensity, which is 20 kpc away, is some distance from the Sagittarius dwarf streamer orbit and is not associated with any known Galactic structure. We have tentatively identified a sixth overdensity in the halo. If this sixth structure is instead part of a smooth distribution of halo stars (the spheroid), then the spheroid must be very flattened, with axial ratio q = 0.5. It is likely that there are many smaller streams of stars in the Galactic halo. C1 Rensselaer Polytech Inst, Dept Phys Appl Phys & Astron, Troy, NY 12180 USA.

This forms the basis for modified Newtonian dynamics, an alternative to particle dark matter. However, any successful theory of galactic dynamics must account for Milgrom's law.

Compared to the field density of Lyalpha emitters, this implies an overdensity on the order of 15. The structure has a projected size of at least 2.7 x 1.8 Mpc and a velocity dispersion of 325 km s(-1), which makes it the most distant structure known. Using the galaxy overdensity and assuming a bias parameter b = 3-5, the mass is estimated to be similar to10(15) M-.. The radio galaxy itself is surrounded by an uniquely asymmetric Lyalpha halo. Taken together with our previous data on PKS 1138-262 at z similar to 2.16, these results suggest that luminous radio sources are excellent tracers of high-density regions in the early universe, which evolve into present-day clusters. The statistics of bright radio sources and of concentrations in the Lyman break galaxy population are consistent with the picture that each of those concentrations harbors an active or passive luminous radio source.

A numerical algorithm is constructed to solve model equations consisting of a fluid approximation of a quasineutral plasma combined with a paraxial light propagation model. The algorithm involves high-resolution plasma and light model discretizations on a block-structured, locally refined grid hierarchy, which is dynamically modified during the time integration to follow evolving fine-scale solution features.

Vibrational characterization resolves small shifts in the positions of some of the peaks when the species were in an ordered layer. On some adsorption sites with reduced symmetry, the vibrational spectra show additional modes. Their observation is attributed to a distortion of the geometry of the adsorbed species.

Blends of symmetric SID and ISD molecules with molecular weights near 10K are miscible and form a gyroid morphology over a wide range of blend compositions. Flory-Huggins interaction parameters for this ABC system allow a detailed interpretation of SAXS, SANS, and DMS measurements. Symmetric SID disorders from the lamellar state, while ISD disorders from hexagonally packed cylinders of D blocks in a mixed matrix of S and I blocks. Block mixing occurs to reduce the number of S-D interactions forced by chemical connectivity in ISD. This drive to minimize unfavorable interactions is the underlying cause of the results outlined in this report. C1 Univ Minnesota, Dept Chem Engn & Mat Sci, Minneapolis, MN 55455 USA.

A current perturbation method in conjunction with drift time measurements was used. Cathode materials included C, Mg, Ti, Cu, Ag, Ta, and Pb with an average arc current of 300 A and 600 mus duration. The measured angular energy distributions are slightly peaked at the cathode normal. Each distribution can be fitted by a superposition of an isotropic component and a cosine function, with the isotropic component dominating. This result is in contrast to plasma jet formation observed by others, which is most likely due to effects of anode geometry and magnetic fields, including the self-field of the current-carrying plasma.

We find that in the low-frequency limit the transmission coefficients of both longitudinal and transverse acoustic phonons agree well with those predicted by the continuum-level based acoustic mismatch model. However, the transmission coefficients rapidly decrease close to the cutoff frequency, a result that can be understood within a simple one-dimensional discrete atomic-chain model. We also find that the transmission coefficient for transverse acoustic phonons depends strongly on the relative orientation of the polarization and the Si-Si bonds in the diamond lattice structure.

The rate constant for the NAr series decreases from 0.27 to 0.0024 L mol(-1) s(-1) at 25 degreesC in benzene as the total number of participating imido groups increases from 2 to 4, indicating that steric effects play an important role in the kinetics of the ligand exchange reactions. But, with NAd, the values of k/L mol(-1) s(-1) are 0.2 (4 NAd), 100 (3 NAd), and 0,74 (2 NAd). The equilibrium constants, also subject to steric effects, are much larger than those predicted by ligand combination statistics and greatly favor the mixed oxo-imido compounds. The different steric demands by imido and oxo ligands are believed to be the main factor for the larger equilibrium constants because the equilibrium constant shows minimal dependence on temperature. The large negative activation entropies for the ligand exchange reactions are consistent with a metathesis mechanism featuring nearly concurrent interchange of oxo and imido groups.

This centroid thermodynamic estimator significantly reduces the numerical noise of the thermodynamic estimator. The debate as to which estimator is better (virial, centroid virial, or thermodynamic) is partially resolved. The centroid estimators are found to be significantly better than their noncentroid analogues. The new centroid thermodynamic estimator has accuracy close to the centroid virial estimator, and may have particular advantages when derivatives of the potential are expensive to evaluate.(C) 2002 American Institute of Physics.

Assignment of the spectra is aided by electronic structure calculations on I-2(-)(CO2). The experiment yields size-dependent vertical and adiabatic detachment energies for the formation of the ground state and low-lying valence-excited states of the neutral cluster. Vertical detachment energies are successively blueshifted with increasing cluster size, indicating a stronger stabilization of the anionic cluster relative to the neutral counterpart. In addition, a short progression in the CO2 bending mode is observed in the n=1 and 2 clusters, indicating that the CO2 solvent species are slightly bent (similar to2.5degrees) in the anion clusters. The trends in the total and stepwise solvation energies are discussed in terms of cluster geometries solute-solvent interactions. (C) 2002 American Institute of Physics.

The 2C3PEPS can be done in an "uphill" or a "downhill" sense, where the first two interactions are of lower (higher) frequency than the final interaction with the radiation field. In both cases no correlation between the two spectral regions is observed at very short times. Different parts of the spectrum gain correlation owing to ultrafast solvent motion and the accompanying Stokes shift. We propose a model for the spectral shift that incorporates a conditional probability distribution for transition frequencies in the two spectral regions. The model qualitatively reproduces all the features of complete numerical simulations. Our results show that memory is partially conserved during the spectral diffusion process from the pump to the probe region. The downhill difference peak shift is very sensitive to the time scale of the inertial component of solvation and seems very promising for an accurate determination of this time scale.

Pores on the zeolite surface provide access to the interior such that hexadecane molecules diffuse inside. The three surfaces studied differ significantly in the rate of molecular diffusion from the surface into the zeolite bulk. An equilibrium concentration of hexadecane inside the zeolite is established as a function of external liquid pressure. Molecules are partially adsorbed inside the zeolite at the solid/liquid interface and a nonuniform distribution of adsorption length is observed, the shape of which is determined by the subsurface channel structure of the zeolite. Near-surface intersections between channels inside the zeolite greatly influence the partial adsorption distribution as molecules preferentially avoid adsorption in intersections. The lifetime of partially adsorbed molecules varied greatly between the three surfaces. The critical adsorption length, at and beyond which molecules are more likely to be adsorbed into the zeolite than desorb into the liquid, also differed for the three interfaces. This too was a function of subsurface channel structure. In the range examined, temperature and pressure are less influential than channel structure. (C) 2002 American Institute of Physics.

Within the spectral resolution of the experiment, no damage to the individual nanoparticles occurs during repeated, prolonged exposure to the intense x-ray beam. Furthermore, no differences in the position or shape of the soft x-ray absorption spectrum of a single nanocrystal and the ensemble are observed within the experimental resolution. PEEM contrast images and soft x-ray absorption spectra, however, show strong intensity variations between different particles reflecting the size distribution of the sample.

We show that: (i) a modest amount of additional information is sufficient to map the continuous GOP into the (discrete) Grover problem; (ii) while this additional information is actually available in some GOPs, it cannot be taken advantage of within classical optimization algorithms; and (iii) quantum algorithms offer a natural framework for the efficient use of this information resulting in a speed-up of the solution of the GOP.

Sep. (1989) 187]. In order to investigate the regeneration behaviour and the operational performance of partially regenerated, rigid gas cleaning filter media over many filtration cycles, experiments were performed in a filter test rig. The regeneration behaviour of the filter sample was characterized by the overall regeneration efficiency, the local frequency of regeneration, and the number and size of regenerated filter areas. Using only four adjustable parameters, our modelling results compare favourably with our experimental results, at room temperature. This favourable comparison of the regeneration behaviour between modelling and experiment is achieved only if it is assumed that cohesive and adhesive bonds, which are broken during filter regeneration, do not heal during the next filtration cycle. Assuming otherwise would cause (i) the dust cake to be removed at the same positions during every regeneration and (it) the patch size to increase from cycle to cycle instead of decreasing as seen in the experiment. Therefore, the model development was guided by our extensive experimental results. This agreement of modelling with experiment indicates that the modelling has real predictive capabilities for operational filter cleaning. Both filter conditioning and dust cake compression significantly influence the operational performance of partially regenerated filter media. (C) 2002 Elsevier Science B.V. All rights reserved.

These phase transformations are further influenced by the cooling rate that the weld experiences and thus by the type of welding process that is used. In this research, microstructure development of a low-alloy steel weld was investigated under the high cooling rates produced by stationary arc welds. These welding conditions are different from the slow weld-cooling conditions, where delta-ferrite forms as the primary solidification phase. The cooling rates of the stationary welds used in this study were of the order of 10(3) K s(-1), which were high enough to induce the formation of the non-equilibrium austenite phase during solidification. This non-equilibrium mode of solidification was directly observed using an in situ time-resolved X-ray diffraction technique using synchrotron radiation, and the resulting microstructures were examined using optical microscopy.

Although useful in influencing the emotions of the public and the press, these labels have contributed fairly little to our understanding of joint toxic action. Part of the difficulty is that their underlying toxicological concepts are only defined for two chemical mixtures, while most environmental and occupational exposures are to mixtures of many more chemicals. Furthermore, the mathematical characterizations of synergism and antagonism are inextricably linked to the prevailing definition of 'no interaction,' instead of some intrinsic toxicological property. For example, the US EPA has selected dose addition as the no-interaction definition for mixture risk assessment, so that synergism would represent toxic effects that exceed those predicted from dose addition. For now, labels such as synergism are useful to regulatory agencies, both for qualitative indications of public health risk as well as numerical decision tools for mixture risk characterization. Efforts to quantify interaction designations for use in risk assessment formulas, however, are highly simplified and carry large uncertainties. Several research directions, such as pharmacokinetic measurements and models, and toxicogenomics, should promote significant improvements by providing multi-component data that will allow biologically based mathematical models of joint toxicity to replace these pairwise interaction labels in mixture risk assessment procedures.

Label-free binding assays with optical detection based on reflectometric interference spectroscopy were performed to determine these constants. Different evaluation methods for kinetic measurements were compared. Also, cross-reactivity against two other polycyclic aromatic hydrocarbons, chrysene and pyrene, was checked. The affinity constant between the antibodies and benzo[a]pyrene in homogeneous phase was determined to be K = (5.3 +/- 0.3) x 10(7) M-1 which was in the middle of the usual range of antibody affinities. The association rate constant for the reaction at the surface was determined to be (3.8 +/- 0.9) x 10(5) M-1 s(-1), the dissociation rate constant as (9.7 +/- 0.5) x 10(-3) s(-1). Different evaluation methods applied to the kinetic measurements led to the same results. This antiserum would be suitable for the selective determination of benzo[a]pyrene in concentrated samples.

We present here the results of a set of computations that lead to an atomic model of the cAMP-dependent protein kinase heterodimer, Delta(1-91)R(IIalpha)-C-alpha. The first step in the modeling utilized the crystal structures for the porcine C-alpha and bovine Delta(1-90)R(Ialpha) or rat Delta(1-111)R(IIbeta), to homology-model structures of the species and isoforms that had been used in the neutron scattering experiments (bovine C-alpha subunit and murine Delta(1-91)R(IIalpha) subunit, respectively). A docking procedure, constrained by the dimensions and positions of the ellipsoids in the neutron-derived R-C model as well as mutagenesis data, was used to develop "best fit" models for the heterodimer. Simulated annealing, molecular dynamics, and energy minimization were then used to refine the side chain packing at the heterodimer interface. For comparison, the calculations were done using the homology models derived from both the R-Ialpha and R-IIbeta crystal structures. Both resultant models had many similarities. Each predicted similar interfaces. The R-Ialpha-based model has 25% more hydrogen bonds than that based on R-IIbeta, with seven of these potential bonds in common. The distribution of hydrophobic, polar, and charged residues at the interface was similar for both models, with a distribution more characteristic of the exposed surface residues than those in the protein interior. The calculated interface area in each is relatively small (<2000 Angstrom(2)). The R-Ialpha-based model, however, has a significantly better fit with the scattering data and is therefore the one of distinctly higher probability. With its small interface area that has a high proportion of charged and polar residues, the complex appears poised for dissociation, and each subunit existing as a stable entity. This result is consistent with the known physiological events required for cAMP-dependent activation of the kinase. C1 Los Alamos Natl Lab, Biosci Div, Los Alamos, NM 87545 USA.

Ten 10 ns trajectories of the folded hairpin 5'-GGGC[GCAA]GCCU-3' were generated using stochastic dynamics and the GB/SA implicit solvent model at 300 K. Overall, we find the stem to be a very stable subunit of this molecule, whereas multiple loop conformations and transitions between them were observed. These trajectories strongly suggest that extension of the C6 base away from the loop occurs cooperatively with an N-type --> S-type sugar pucker conversion in that residue and that similar pucker transitions are necessary to stabilize other looped-out bases. In addition, a short-lived conformer with an extended fourth loop residue (M) lacking this stabilizing 2'-endo pucker mode was observed. Results of thermal perturbation at 400 K support this model of loop dynamics. Unfolding trajectories were produced using this same methodology at temperatures of 500 to 700 K. The observed unfolding events display three-state behavior kinetically (including native, globular, and unfolded populations) and, based on these observations, we propose a folding mechanism that consists of three distinct events: (i) collapse of the random unfolded structure and sampling of the globular state; (ii) passage into the folded region of configurational space as stem base-pairs form and gain helicity; and (iii) attainment of proper loop geometry and organization of loop pairing and stacking interactions. These results are considered in the context of current experimental knowledge of this and similar nucleic acid hairpins. (C) 2002 Elsevier Science Ltd.

The convergent method involves the preparation of ligands in solution and their subsequent attachment to the support. The divergent approach is based on the stepwise "on-bead" formation of the linker using methods that are typical of solid-phase synthesis. While the convergent CSPs feature well-defined ligands, their loading is relatively low. In contrast, the divergent technique affords CSPs with higher loading but with more limited control over precise ligand architecture. Excellent enantioselectivities characterized by separation factors of up to 31 were achieved for the separation of racemic N-(3,5dinitrobenzoyl)-alpha-amino acid alkyl amides with these new CSPs under normal-phase HPLC conditions.

Interaction with ligands triggers tertiary and quaternary structural rearrangements in integrins that are needed for cell signaling. Here we report the crystal structure of the extracellular segment of integrin alphaVbeta3 in complex with a cyclic peptide presenting the Arg-Gly-Asp sequence. The ligand binds at the major interface between the alphaV and beta3 subunits and makes extensive contacts with both. Both tertiary and quaternary changes are observed in the presence of ligand. The tertiary rearrangements take place in betaA, the ligand-binding domain of beta3; in the complex, betaA acquires two cations, one of which contacts the ligand Asp directly and the other stabilizes the ligand-binding surface. Ligand binding induces small changes in the orientation of alphaV relative to beta3.

Subsequent workers argued that the mechanism for HOONO decomposition proceeds via homolytic bond fission, producing the radical pair OH and NO(2), and another recent study argued that a cyclic form of the peroxynitrous acid results in the products H(+) + O(2)((1)Delta(g)) + NO(-). Calculations on the reaction pathway for the process showed that it required a high activation energy, and is thus implausible. High level ab initio molecular orbital theory including extrapolation to the complete basis set limit has been used to calculate the heats of formation of reactants and products for the homolytic bond fission pathways for decomposition of HOONO and the molecular pathway that yields HNO and (1)O(2) as well as the transition state for the latter process. These data are used to evaluate the probability of whether the decomposition of peroxynitrous acid can produce HNO and (1)O(2). Isomerization of HOONO to HONO(2) is also discussed.

A Ramachandran plot, with the angle phi in the range -180degrees to 90degrees and the angle V) in the range -60degrees to 180degrees, was generated by using density functional theory with the generalized-gradient BLYP functional and a polarized triple-zeta basis set (TZVP+). Six conformers, C7,q, C5, C7(ax), beta(2), alpha(L), and alpha', have been identified in this region of the Ramachandran plot. A second derivative (frequency) analysis showed that all conformers are stable at this level of theory. These structures were used as starting points for geometry optimizations at the MP2/aug-cc-pVDZ level. Single-point energies were calculated at the MP2/aug-cc-pVTZ and MP2/aug-cc-pVQZ levels at the final MP2/aug-cc-pVDZ structures and together with the MP2/aug-cc-pVDZ results were used in extrapolations to the complete basis set limit. The N-H...O, N-H...N, and C-H...O hydrogen bond interactions that are key to the energetics are discussed. In general, the results obtained at the BLYP/TZVP+, MP2/aug-cc-pVDZ, MP2/aug-cc-pVTZ//aug-cc-pVDZ, and MP2/aug-cc-pVQZ//aug-cc-pVDZ levels are in reasonable agreement with each other, except for the beta(2) conformation for which there are significant differences in the structures. Although the same stability order is obtained at all levels of theory that were used, there are significant differences in the magnitude of the relative conformational energies.

PARTON DISTRIBUTIONS; JET PHOTOPRODUCTION; HADRON-COLLISIONS; P(P)OVER-BAR COLLISIONS AB Dijet differential cross sections for the reaction e(-)p --> e(+) jet + jet + X in the photoproduction regime have been measured with the ZEUS detector at HERA using an integrated luminosity of 42.7 pb(-1), The cross sections are given for photon-proton centre-of-mass energies in the range 134 < W < 277 GeV The differential cross sections as a function of the dijet mass, M-jj, and of the dijet angular variables have been measured for 47 < M-jj < 160 GeV and compared to next-to-leading-order QCD calculations. The dijet events in the region 75 < M-jj < 100 GeV have been used to derive a 95% C.L. upper limit on the cross section for Z(0) photoproduction of sigma(e+ p --> e+ Z0X) < 5.9 pb. Upper limits on the photoproduction of new heavy resonances decaying into two jets are also presented for masses in the range between 60 GeV and 155 GeV (C) 2002 Elsevier Science B.V.

PRODUCTION; POMERON; HERA AB Using the D empty set detector, we have studied events produced in (p) over barp collisions that contain large forward regions with very little energy deposition ("rapidity gaps") and concurrent jet production at center-of-mass energies of roots = 630 and 1800 GeV. The fraction of events with forward or central jets associated with rapidity gaps is compared to predictions for hard diffraction. We also extract the momentum loss for scattered protons in such processes. (C) 2002 Elsevier Science B.V. All rights reserved. C1 Joint Inst Nucl Res, Dubna, Russia.

Unless this is an coincidence caused by fortuitous Planck-scale physics, it suggests the presence of an SU(3) symmetry near the electroweak scale. We propose this to be a local SU(3) which spontaneously "mixes" with SU(2) x U(1) near a TeV. Although all the particles of the standard model are SU(3)-singlets, this symmetry relates the electroweak gauge couplings and can successfully predict the weak mixing angle with a precision of a few percent. Since this mechanism operates at a TeV, it does not require an energy desert and consequently can be embedded in theories of TeV-gravity. (C) 2002 Published by Elsevier Science B.V.

In this Letter we use exact analytical and numerical results to show that the contribution of vertex dressings to the two-body bound state mass for scalar QED are cancelled by the self-energy and wavefunction normalization, This proves, for the first time. that the mass of a two-body bound state given by the full theory can in a very good approximation be obtained by summing only ladder and crossed ladder diagrams using a bare vertex and a constant dressed mass. We also discuss the implications of the remarkable cancellation between rainbow and crossed rainbow diagrams that is a feature of one-body calculations. (C) 2002 Elsevier Science B.V.

In the experiments described in this paper, the detachment of oil droplets from a solid surface in aqueous surfactant solutions was studied and the variation in droplet shape, particularly contact angle, and the time required for droplet detachment were measured. In parallel, tests of oil removal from solid surfaces in an industrial ultrasonic bath were conducted under conditions similar to drop-detachment tests. Consistent trends were found in both types of tests; that is, conditions for which droplets detach more quickly correspond to conditions of greater oil removal in an ultrasonic bath. At high pH, faster drop-detachment (and oil removal) kinetics were observed when the oil-water interface was negatively charged (per xipotential measurements). In contrast, at low-pH conditions, faster kinetics were observed when the solid-liquid interface was positively charged. The pH effect is consistent with a mechanistic model in which electrostatic interactions and solid-surface hydrophobicity changes due to surfactant adsorption onto solid surfaces under various pH conditions are considered. This study also demonstrated that single-drop-detachment tests and/ or xi-potential measurements are useful as simple, timesaving screening methods for selecting promising conditions for specific cleaning applications.

It was found that the introduction of the Z-double bond between C-9 and C-10 of the parent substrate occurs with pro-R enantioselectivity-a result that accounts for the observed stereochemistry of oxidation products derived from (9R)- and (9S)-9-fluorostearoyl-ACP. Oxidation of (9R)-9-fluorostearoyl-ACP occurs via at least two rapidly interchanging substrate conformations in the active site as detected by reaction pathway branching induced by deuteration at C-10 and C-11. Hydroxylation and desaturation of this substrate share the same site of initial oxidative attack. C1 Brookhaven Natl Lab, Dept Biol, Upton, NY 11973 USA.

Several molecular dynamics simulations have bean performed for the two rotational isomers A and B, which are related by a 180degrees rotation around the alpha-gamma axis of the hems, of sperm-whale carbonmonoxy myoglobin in water. Both neutron diffraction and NMR structures were used as starting structures. In the absence of an experimental structure, the structure of isomer B was generated by rotating the hems in the structure of isomer A. Distortions of the hems from planarity were characterized by normal coordinate structural decomposition and by the angle of twist of the pyrrole rings from the hems plane. The hems distortions of the neutron diffraction structure were conserved in the MD trajectories, but in the NMR-based trajectories, where the hems distortions are less well defined, they differ from the original hems deformations. The protein matrix induced similar distortions on the heroes in orientations A and B. Our results suggest that the binding site prefers a particular macrocycle conformation, and a 180degrees rotation of the hems does not significantly alter the protein's preference for this conformation. The intrinsic rotational strengths of the two Soret transitions, separated according to their polarization in the hems plane, show strong correlations with the ruffling deformation and the average Twist angle of the pyrrole rings. The total rotational strength, which includes contributions from the chromophores in the protein, shows a weaker correlation with hems distortions.

Thermal cycling results in enhanced densification kinetics as compared to isothermal compaction at the upper cycle temperature. Using mechanistic models of initial-stage powder densification, the experimental data are analyzed to reveal the creep stress-exponent and activation energy of the dominant densification mechanism. Consequently, the observed densification enhancement during thermal cycling is confirmed to be due to internal stress plasticity, which is produced by internal mismatch stresses between adjacent zinc grains with anisotropic thermal expansion.

We have monitored the grain boundary profile, triple junction angles and rate of grain boundary migration with and without triple junctions as a function of grain size, grain misorientation, direction of migration and temperature in a series of configurations designed to ensure steady-state migration. The present results demonstrate that triple junction mobility is finite and can be sufficiently small to limit the rate of grain boundary migration. The drag on grain boundaries due to limited triple junction mobility is important at small grain sizes, low temperature and near high symmetry grain misorientations. This drag limits the rate of grain boundary migration and leads to triple junction angles that differ substantially from their equilibrium value. Simulation data suggest that triple junction drag is much more a factor at low temperature than at high temperature. The triple junction mobility is shown to depend upon the direction of triple junction migration. The present results are in excellent qualitative agreement with experimental observations.

The sample was loaded using a dedicated Instron hydraulic load frame on the ENGIN station of the PEARL beam line at the ISIS facility of the Rutherford Appleton Laboratory. The load frame was aligned to allow simultaneous monitoring of longitudinal and transverse lattice strain components. There was a strong experimental hkl-dependency of the lattice strain response in both the effective stiffness and in the lattice strain loop hysteresis. The experimental data were compared with numerical predictions obtained from a self-consistent elasto-plastic model for the simulation of polycrystal deformation. A cyclic hardening law was developed and implemented into the modelling scheme, providing theoretical predictions in good agreement with experimental observations. (C) 2002 Acta Materialia Inc.

Here we report extensive pulse radiolysis studies on recombinant two-iron SOR (2Fe-SOR) from Desulfovibrio vulgaris. The results support and elaborate on our originally proposed scheme for reaction of the [Fe(NHis)(4)(SCys)] site with superoxide [Coulter, E. D., Emerson, J. E., Kurtz, D. M., Jr., and Cabelli, D. E. (2000) J. Am. Chem. Soc. 122, 11555-11556]. This scheme consists of second-order diffusion-controlled formation of an intermediate absorbing at similar to600 nm, formulated as a ferric-(hydro)peroxo species, and its decay to the carboxylate-ligated ferric [Fe(NHis)(4)(SCys)] site with loss of hydrogen peroxide. The second-order rate constant for formation of the 600-nm intermediate is essentially pH-independent (pH 5-9.5), shows no D2O solvent isotope effect at pH 7.7, and decreases with increasing ionic strength. These data indicate that formation of the intermediate does not involve a rate-determining protonation, and are consistent with interaction of the incomina superoxide anion with a positive charge at or near the ferrous [Fe(NHis)(4)(SCys)] site. The rate constant for decay of the 600-nm intermediate follows the pH-dependent rate law: k(2)(obs) = k(2)'[H+] + k(2)" and shows a significant D2O solvent isotope effect at pH 7.7. The values of k(2)' and k(2)" indicate that the 600-nm intermediate decays via diffusion-controlled protonation at acidic pHs and a first-order process involving either water or a water-exchangeable proton on the protein at basic pHs. The formation and decay rate constants for an E47A variant of 2Fe-SOR are not significantly perturbed from their wild-type values, indicating that the conserved glutamate carboxylate does not directly displace the (hydro)peroxo ligand of the intermediate at basic pHs. The kinetics of a K48A variant are consistent with participation of the lysyl side chain in directing the superoxide toward the active site and in directing the protonation pathway of the ferric- (hydro)peroxo intermediate toward release of hydrogen peroxide.

The vibrational distribution formed appears much colder than the distribution resulting from gas-phase photodissociation of CH3I. Measurements of the surface reaction cross-section versus photon exposure and time-of-flight (TOF) studies of the CH3 translational energy suggest that the colder temperature is attributable to dissociative electron attachment (DEA) by photoemitted substrate electrons.

Switching from 8 to 30 nt mode is associated with a large conformational change. Here we report the 2.8 Angstrom structure of the RPA trimerization core comprising the C-terminal DNA-binding domain of subunit RPA70 (DBD-C), the central DNA-binding domain of subunit RPA32 (DBD-D) and the entire RPA14 subunit. All three domains are built around a central oligonucleotide/oligosaccharide binding (OB)fold and flanked by a helix at the C-terminus. Trimerization is mediated by three C-terminal helices arranged in parallel. The OB-fold of DBD-C possesses unique structural features; embedded zinc ribbon and helix-turn-helix motifs. Using time-resolved proteolysis with trypsin, we demonstrate that the trimerization core does not contribute to the binding with substrates of 10 nt, but interacts with oligonucleotides of 24 nt. Taken together, our data indicate that switching from 8-10 to 30 nt mode is mediated by DNA binding with the trimerization core.

The model includes equilibrium reactions for the aqueous species, kinetic reactions between the solid and aqueous phases, and full coupling of porosity and permeability changes that result from precipitation and dissolution reactions in porous media. A one-step, global implicit approach is used to solve the coupled flow, transport and reaction equations with a fully implicit upstream-weighted control volume discretization. The Newton Raphson method is applied to the discretized non-linear equations and a block ILU-preconditioned CGSTAB method is used to solve the resulting Jacobian matrix equations. This approach permits the solution of the complete set of governing equations for both concentration and pressure simultaneously affected by chemical and physical processes. A series of chemical transport simulations are conducted to investigate coupled processes of reactive chemical transport and density-dependent flow and their subsequent impact on the development of preferential flow paths in porous media. The coupled effects of the processes driving flow and the chemical reactions occurring during solute transport is studied using a carbonate system in fully saturated porous media. Results demonstrate that instability development is sensitive to the initial perturbation caused by density differences between the solute plume and the ambient groundwater. If the initial perturbation is large, then it acts as a "trigger" in the flow system that causes instabilities to develop in a planar reaction front. When permeability changes occur due to dissolution reactions occurring in the porous media, a reactive feedback loop is created by calcite dissolution and the mixed convective transport of the system. Although the feedback loop does not have a significant impact on plume shape, complex concentration distributions develop as a result of the instabilities generated in the flow system.

Heat transfer from the reactor wall normally supplies the required energy, in such processes. Drawbacks, such as operating temperature constraints and practical heat-transfer restrictions, limit this practice. In such situations, microwave heating could provide an effective and efficient method for transferring heat to the catalyst. To explore this possibility the methanol-steam reaction performed by Conventional heating and microwave heating it-as studied Mathematical modeling was performed for I-D heat transfer in a single catalyst pellet and for 2-D heat transfer in a tubular packed-bed reactor. The single catalyst pellet model indicated that productivity could increase significantly using microwave heating. The 2-D model showed that microwave heating could minimize radial heat-transfer effects. Conducting the methanol-steam reaction in a microwave-heated reactor experimentally verified the improved productivity. C1 Univ New Mexico, Albuquerque, NM 87131 USA.

Utilizing three-step resonant excitation into an autoionizing level, both isobaric and isotopic selectivity of >10(7) were attained. An overall detection efficiency of similar to10(-7) and an isotope specific detection limit of 1.5x10(9) atoms have been demonstrated. When targeting the major isotope Gd-158, this corresponds to a total Gd detection limit of 1.6 pg. Additionally, linear response has been demonstrated over a dynamic range of six orders of magnitude. The method has been used to determine the Gd content in various normal and tumor tissue samples, taken from a laboratory mouse shortly after injection of gadolinium diethylenetriaminepentaacetic acid dimeglumine (Gd-DTPA), which is used as a contrast agent for magnetic resonance imaging (MRI). The RIMS results show Gd concentrations that vary by more than two orders of magnitude (0.07-11.5 mug mL(-1)) depending on the tissue type. This variability is similar to that observed in MRI scans that depict Gd-DTPA content in the mouse prior to dissection, and illustrates the potential for quantitative trace analysis in microsamples of biomedical materials.

Incorporation of stable-isotope-labeled (SIL) amino acids into a protein of interest during overexpression in bacteria produced distinctive isotope patterns in mass spectra of peptic peptides from the labeled protein. The isotope pattern was used as a signature for peptides originating from the SIL protein. In addition, stable-isotope labeling simplified identification of the peptic peptides by providing partial amino acid composition information. Despite the complex isotope patterns associated with SIL peptides, hydrogen exchange rates could still be measured for peptides from SIL protein and were found to be the same as exchange rates for unlabeled protein. Hydrogen exchange in a single protein of interest was measured in a complex mixture of proteins, a bacterial cell lysate. This methodology, which includes easy recognition of peptic peptides from the protein(s) of interest during hydrogen exchange studies in heterogeneous systems, will permit analysis of structural properties and dynamics of large protein complexes and complex protein systems.

Consequently, the suspected modified peptides are subjected to tandem MS/MS sequencing that may demand more time and sample. We report the use of stable isotope-enriched amino acids as residue-specific "mass signatures" for the rapid and sensitive detection of protein modifications directly from the peptide mass map (PMM) without enrichment of the modified peptides. These mass signatures are easily recognized through their characteristic spectral patterns and provide fingerprints for peptides containing the same content of specific amino acid residue(s) in a PMM. Without the need for tandem MS/MS sequencing, a peptide and its modified form(s) can readily be identified through their identical fingerprints, regardless of the nature of modifications. In this report, we demonstrate this strategy for the detection of methionine oxidation and protein phosphorylation. More interestingly, the phosphorylation of a histone protein, H2A.X, obtained from human skin fibroblast cells, was effectively identified in response to low-dose radiation. In general, this strategy of residue-specific mass tagging should be applicable to other posttranslational modifications. C1 Los Alamos Natl Lab, C ACS, Div Chem, Los Alamos, NM 87544 USA.

The composition of the microbial communities was assessed by bulk DNA extraction, PCR amplification of 16S ribosomal DNA fragments, separation of these fragments by denaturing gradient gel electrophoresis, and sequence analysis. Community function was assessed by measurement of beta-glucosidase and aminopeptidase extracellular enzyme activities. Free-living populations in the aqueous phase exhibited a greater diversity of phylotypes than populations associated with the solid phase. The attached bacterial community displayed significantly greater beta-glucosidase and aminopeptidase enzyme activities per volume of porous medium than those of the free-living community. On a per-cell basis, the attached community had a significantly higher cell-specific aminopeptidase enzyme activity (1.07 X 10(-7) nmol cell(-1) h(-1)) than the free-living community (5.02 X 10(-8) nmol cell(-1) h(-1)). Conversely, the free-living community had a significantly higher cell-specific beta-glucosidase activity (1.92 X 10(-6) nmol cell(-1) h(-1)) than the surface-associated community (6.08 X 10(-7) nmol cell(-1) h(-1)). The compositional and functional differences observed between these two communities may reflect different roles for these distinct but interacting communities in the decomposition of natural organic matter or biodegradation of xenobiotics in aquifers.
