description: Recent observation of intrinsic ferromagnetism in two-dimensional (2D) CrI$_3$ is associated with the large magnetic anisotropy due to strong spin-orbit coupling (SOC) of I. Magnetic anisotropy energy (MAE) defines the stability of magnetization in a specific direction with respect to the crystal lattice and is an important parameter for nanoscale applications. In this work we apply the density functional theory to study the strain dependence of MAE in 2D monolayer chromium trihalides CrX$_3$ (with X = Cl, Br, and I). Detailed calculations of their energetics, atomic structures and electronic structures under the influence of a biaxial strain $\varepsilon$ have been carried out. It is found that all three compounds exhibit ferromagnetic ordering at the ground state (with $\varepsilon$=0) and upon applying a compressive strain, phase transition to antiferromagnetic state occurs. Unlike in CrCl$_3$ and CrBr$_3$, the electronic band gap in CrI$_3$ increases when a tensile strain is applied. The MAE also exhibits a strain dependence in the chromium trihalides: it increases when a compressive strain is applied in CrI$_3$, while an opposite trend is observed in the other two compounds. In particular, the MAE of CrI$_3$ can be increased by 47\% with a compressive strain of $\varepsilon$ = 5\%.

Concerning the anomalous kinetic behavior of microtubules

description: We have demonstrated that tubulin-GTP subunits can react with microtubule ends containing subunits with E-site-bound GDP. This observation can be taken to rule out a previous interpretation of a biphasic dependence of the rate for subunit flux into microtubules on the subunit concentration, which is based upon an assumption that GTP is required to be present in subunits at microtubule ends in order to allow addition of tubulin-GTP subunits. The nullified mechanism had been suggested to be the basis of the observation that growing and shrinking microtubules coexist as independent species. We have also confirmed previous studies indicating that the flux rate is nonlinearly dependent on the subunit concentration and account for this behavior by assuming that tubulin-GTP subunits reversibly add to microtubule ends by two paths. In one, tubulin-GTP subunits add nonproductively to generate an end which is unable to undergo further net microtubule elongation; however, this reaction can retard the rate for microtubule disassembly under conditions where the disassembly reaction predominates. In the other, tubulin-GTP subunits add productively to microtubule ends to generate ends which can undergo subsequent net elongation.

description: Maltose-binding protein (MBP) is essential for maltose transport and chemotaxis in Escherichia coli. To perform these functions it must interact with two sets of cytoplasmic membrane proteins, the MalFGK transport complex and the chemotactic signal transducer Tar. MBP is present at high concentrations, on the order of 1 mM, in the periplasm of maltose-induced or malTc constitutive cells. To determine how the amount of MBP affects transport and taxis, we utilized a series of malE signal-sequence mutations that interfere with export of MBP. The MBP content in shock fluid from cells carrying the various mutations ranged from 4 to 23% of the malE+ level. The apparent Km for maltose transport varied by less than a factor of 2 among malE+ and mutant strains. At a saturating maltose concentration 9% (approximately 90 microM) of the malE+ amount of MBP was required for half-maximal uptake rates. Transport exhibited a sigmoidal dependence on the amount of periplasmic MBP, indicating that MBP may be involved in a cooperative interaction at some stage of the transport process. The chemotactic response to a saturating maltose stimulus exhibited a first-order dependence on the amount of periplasmic MBP. Thus, interaction of a single substrate-bound MBP with Tar appears sufficient to initiate a chemotactic signal from the transducer. A half-maximal chemotactic response occurred at 25% of the malE+ MBP level, suggesting that in vivo the KD for binding of maltose-loaded MBP to Tar is quite high (approximately 250 microM).

description: Since 2011, the Global Energy and Water cycle Exchanges (GEWEX) Water Vapor Assessment (G-VAP) has provided performance analyses for state-of-the-art reanalysis and satellite water vapour products to the GEWEX Data and Analysis Panel (GDAP) and the user community in general. A significant component of the work undertaken by G-VAP is to characterise the quality and uncertainty of these water vapour records to (i) ensure full exploitation and (ii) avoid incorrect use or interpretation of results. This study presents results from the second phase of G-VAP, where we have extended and expanded our analysis of total column water vapour (TCWV) from phase 1, in conjunction with updating the G-VAP archive. For version 2 of the archive, we consider 28 freely available and mature satellite and reanalysis data products, remapped to a regular longitude–latitude grid of 2° × 2° and on monthly time steps between January 1979 and December 2019. We first analysed all records for a “common” short period of 5 years (2005–2009), focusing on variability (spatial and seasonal) and deviation from the ensemble mean. We observed that clear-sky daytime-only satellite products were generally drier than the ensemble mean, and seasonal variability/disparity in several regions up to 12 kg m−2 related to original spatial resolution and temporal sampling. For 11 of the 28 data records, further analysis was undertaken between 1988–2014. Within this “long period”, key results show (i) trends between −1.18 ± 0.68 to 3.82 ± 3.94 kg m−2 per decade and −0.39 ± 0.27 to 1.24 ± 0.85 kg m−2 per decade were found over ice-free global oceans and land surfaces, respectively, and (ii) regression coefficients of TCWV against surface temperatures of 6.17 ± 0.24 to 27.02 ± 0.51 % K−1 over oceans (using sea surface temperature) and 3.00 ± 0.17 to 7.77 ± 0.16 % K−1 over land (using surface air temperature). It is important to note that trends estimated within G-VAP are used to identify issues in the data records rather than analyse climate change. Additionally, breakpoints have been identified and characterised for both land and ocean surfaces within this period. Finally, we present a spatial analysis of correlations to six climate indices within the long period, highlighting regional areas of significant positive and negative correlation and the level of agreement among records.

Pheidole barbata Wheeler 1908h: 448.
types Amer. Mus. Nat. Hist.; Mus. Comp. Zool. Harvard.
etymology L barbata, bearded, alluding to the long, coarse hairs on the ventral head surface of the minor.
diagnosis A member of the " bicarinata complex" of the larger pilifera group, comprising agricola, aurea, barbata, bicarinata, centeotl, cerebrosior, defecta, gilvescens, macclendoni, macrops, marcidula, paiute, pinealis, psammophila, vinelandica, xerophila, yaqui, and yucatana (barbata is closest to psammophila), which complex is characterized by the large to very large, forward-set eyes of both castes; and, in the major, the occipital lobes lacking any sculpturing (except in aurea), the posterior half of the head capsule smooth and shiny; and the postpetiolar node seen from above oval, elliptical, or laterally angulate (cornulate in cerebrosior).
P. barbata is distinguished by the absence of propodeal spines in both castes. Further: in the major, teeth absent on the hypostoma; humerus very prominently lobose in dorsal-oblique view; and spinose subpetiolar process seen in side view.
Minor: very long coarse hairs (psammophore?) line the ventral surface of the head; petiolar and postpetiolar nodes very low.
Measurements (mm) Major (Rancho Dos Palmas, California): HW 1.62, HL 1.72, SL 0.74, EL 0.26, PW 0.72.
Syntype minor: HW 0.44, HL 0.54, SL 0.52, EL 0.18, PW 0.30.
color Major: head brownish yellow, with occiput and area around midcenter line light brown; mesosoma, waist, and antennae brownish yellow; legs medium yellow. Minor: concolorous light yellowish brown.
Range Western Arizona, southern Nevada, and southeastern California (Creighton and Gregg 1955; G. C. and J. N. Wheeler 1973e, 1986g).
Biology According to Creighton and Gregg (1955), barbata is a desert species, which prefers to nest in light, sandy soil, although it also lives in coarse, hard-packed sand along the edges of arroyos. The nest is surmounted by a low crater 5-10 cm in diameter, and it is sometimes also surrounded by a chaff ring, suggesting that barbata is a harvester ant. Colonies excavated by Creighton comprised up to 11 majors and 73 minors, although this may be an underestimate of the real population size, since no nest queen was ever found. Similar nest structures were encountered in Deep Canyon, near Palm Springs, California, by G. C. and J. N. Wheeler (1973e).

description: KM3NeT is a research infrastructure housing the next generation neutrino detectors in the depths of the Mediterranean Sea. The ARCA detector, which is currently under construction, is optimized for searches for neutrinos from astrophysical sources as well as measurements of the diffuse astrophysical flux. The unambiguous detection of neutrinos of extraterrestrial origin by IceCube has led to the first measurement of a high energy astrophysical neutrino flux. The properties of sea water allow for a measurement of the neutrino direction with an excellent angular resolution for both track and cascade events. Here a method to differentiate track and shower events and a method to reject the atmospheric muon background from starting track-like events are combined in one analysis. The analysis on the discovery potential of KM3NeT/ARCA for a diffuse astrophysical neutrino flux using events with the reconstructed vertex inside the detector volume will be presented.

description: The investigation of triggers causing the onset and intensification of Northern Hemisphere Glaciation (NHG) during the late Pliocene is essential for understanding the global climate system, with important implications for projecting future climate changes. Despite their critical roles in the global climate system, influences of land-ocean interactions on high-latitude ice sheets remain largely unexplored. Here, we present a high-resolution Asian dust record from Ocean Drilling Program Site 1208 in the North Pacific, which lies along the main route of the westerlies. Our data indicate that atmosphere-land-ocean interactions affected aeolian dust emissions through modulating moisture and vegetation in dust source regions, highlighting a critical role of terrestrial systems in initiating the NHG as early as 3.6 Myr ago. Combined with additional multi-proxy and model results, we further show that westerly wind strength was enhanced, mainly at low-to-middle tropospheric levels, during major glacial events at about 3.3 and 2.7 Myr ago. We suggest that coupled responses of Earth’s surface dynamics and atmospheric circulation in the Plio-Pleistocene likely involved feedbacks related to changes in paleogeography, ocean circulation, and global climate.
Interconversion of androgen receptor forms by divalent cations and 8 S androgen receptor-promoting factor. Effects of Zn2+, Cd2+, Ca2+, and Mg2+
Creators: name: Wilson, E M
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1985

description: The effects of divalent cations (Zn2+, Cd2+, Ca2+, Mg2+) on the cytosol androgen receptor were determined by sedimentation into sucrose gradients. At low ionic strength (25 mM KCl, 50 mM Tris, pH 7.4), Zn2+ (200 microM total, which calculates to 130 nM free Zn2+ in 10 mM mercaptoethanol) causes a shift in the sedimentation coefficient of the rat Dunning prostate tumor (R3327H) cytosol receptor and rat ventral prostate cytosol receptor from 7.5 +/- 0.3 S to 8.6 +/- 0.3 S. Zn2+ stabilizes the 8.6 S receptor form in salt concentrations up to 0.15 M KCl in 50 mM Tris, pH 7.2. In low ionic strength gradients containing Ca2+ (greater than or equal to 200 microM) or Mg2+ (greater than or equal to 1 mM), the receptor sediments as 4.7 +/- 0.3 S. The dissociating effects of Ca2+ and Mg2+ can be fully reversed by sedimentation into gradients containing Zn2+ (200 microM total) or Cd2+ (10 microM total). In the presence of Zn2+ (200 microM total), Ca2+ (10 microM to 3 mM) converts the receptor to an intermediate form with sedimentation coefficient 6.2 +/- 0.2 S, Stokes radius 73 A, and apparent Mr approximately 203,000. The potentiating effect of Zn2+ on formation of the 8.6 S receptor (in the absence of Ca2+) and the 6.2 S receptor (in the presence of Ca2+) requires both the 4.5 S receptor and the 8 S androgen receptor-promoting factor. Sodium molybdate stabilizes the untransformed cytosol receptor but, unlike Zn2+, does not promote reconstitution of the 8.6 S receptor from its partially purified components. These results indicate that divalent cations alter the molecular size of the androgen receptor in vitro and thus may have a role in altering the state of transformation of the receptor.

We use a renormalizable model that guarantees the general validity of our results in the context of short range interactions. The experimental data for one and two-neutron separation energies, implies that among the halo-nuclei candidates, only C-20 has a possible Efimov state, with energy less than 14 KeV below the scattering threshold.

As follows from our calculations, the resonances $f_0(980)$ and $f_0(1500)$ in the $π^+π^-$ and $π^0π^0$ spectra reveal themselves as dips.

description: The heat capacity of a given probe is a fundamental quantity that determines, among other properties, the maximum precision in temperature estimation. In turn, is limited by a quadratic scaling with the number of constituents of the probe, which provides a fundamental limit in quantum thermometry. Achieving this fundamental bound with realistic probes, i.e. experimentally amenable, remains an open problem. In this work, we tackle the problem of engineering optimal thermometers by using networks of spins. Restricting ourselves to two-body interactions, we derive general properties of the optimal configurations and exploit machine-learning techniques to find the optimal couplings. This leads to simple architectures, which we show analytically to approximate the theoretical maximal value of and maintain the optimal scaling for short- and long-range interactions. Our models can be encoded in currently available quantum annealers, and find application in other tasks requiring Hamiltonian engineering, ranging from quantum heat engines to adiabatic Grover's search.

Pheidole carbonaria r. calens Forel 1901d: 130. Raised to species level by Kempf 1972b: 188.
Types Mus. Hist. Nat. Geneve; Mus. Comp. Zool. Harvard.
Etymology Unknown.
diagnosis A member of the " pilifera complex" of the larger pilifera group, comprising calens, californica, carrolli, cavigenis, clementensis, creightoni, hoplitica, littoralis, micula, pilifera, polymorpha, rugulosa, senex, soritis, tepicana, and torosa, which complex is characterized by the following traits. Major: dorsal head surface extensively sculptured; occipital lobes horizontally rugulose (or, in carrolli smooth, in littoralis foveate, and in micula and soritis carinulate); postpetiole from above diamond-shaped, trapezoidal, or spinose. Minor: eye medium-sized to large.
P. calens is distinguished within this complex by the following combination of traits.
Major: posterior dorsal profile of head weakly concave; humerus in dorsal-oblique view prominent and sub-rectangular; mesonotal convexity prominent; petiolar node in side view thin; postpetiole from above laterally spinose.
Minor: eyes very large; propodeal spine in side view equilaterally triangular.
Measurements (mm) Syntype major: HW 1.30, HL 1.50, SL 0.64, EL 0.14, PW 0.66.
Syntype minor: HW 0.56, HL 0.64, SL 0.50, EL 0.20, PW 0.34.
Color Major: concolorous light reddish brown.
Minor: body concolorous plain medium brown, mandibles yellow, legs light brown.
Range Known only from the type locality.
Biology P. calens appears to be a commensal of the large harvesting ants in the genus Pogonomyrmex. Wheeler (190 lh), in his notes to Auguste Forel on the type series, reported as follows: "This feeble Pheidole was found in a number of instances inhabiting small nests within the precincts of the Pogonomyrmex colonies, either on the denuded disks or on the slopes of the gravel cones near the entrances of the agriculturals. It was seen more frequently in this association than either Dorymyrmex pyramicus or Forelius maccooki, and was not seen nesting by itself as is very frequently the case with these species."

description: Control of materials through custom design of ionic distributions represents a powerful new approach to develop future technologies ranging from spintronic logic and memory devices to energy storage. Perovskites have shown particular promise for ionic devices due to their high ion mobility and sensitivity to chemical stoichiometry. In this work, we demonstrate a solid-state approach to control of ionic distributions in (La,Sr)CoO$_{3}$ thin films. Depositing a Gd capping layer on the perovskite film, oxygen is controllably extracted from the structure, up-to 0.5 O/u.c. throughout the entire 36 nm thickness. Commensurate with the oxygen extraction, the Co valence state and saturation magnetization show a smooth continuous variation. In contrast, magnetoresistance measurements show no-change in the magnetic anisotropy and a rapid increase in the resistivity over the same range of oxygen stoichiometry. These results suggest significant phase separation, with metallic ferromagnetic regions and oxygen-deficient, insulating, non-ferromagnetic regions, forming percolated networks. Indeed, X-ray diffraction identifies oxygen-vacancy ordering, including transformation to a brownmillerite crystal structure. The unexpected transformation to the brownmillerite phase at ambient temperature is further confirmed by high-resolution scanning transmission electron microscopy which shows significant structural - and correspondingly chemical - phase separation. This work demonstrates room-temperature ionic control of magnetism, electrical resistivity, and crystalline structure in a 36 nm thick film, presenting new opportunities for ionic devices that leverage multiple material functionalities.

description: The higher classification of termites requires substantial revision as the Neoisoptera, the most diverse termite lineage, comprise many paraphyletic and polyphyletic higher taxa. Here, we produce an updated termite classification using genomic-scale analyses. We reconstruct phylogenies under diverse substitution models with ultraconserved elements analyzed as concatenated matrices or within the multi-species coalescence framework. Our classification is further supported by analyses controlling for rogue loci and taxa, and topological tests. We show that the Neoisoptera are composed of seven family-level monophyletic lineages, including the Heterotermitidae Froggatt, Psammotermitidae Holmgren, and Termitogetonidae Holmgren, raised from subfamilial rank. The species-rich Termitidae are composed of 18 subfamily-level monophyletic lineages, including the new subfamilies Crepititermitinae, Cylindrotermitinae, Forficulitermitinae, Neocapritermitinae, Protohamitermitinae, and Promirotermitinae; and the revived Amitermitinae Kemner, Microcerotermitinae Holmgren, and Mirocapritermitinae Kemner. Building an updated taxonomic classification on the foundation of unambiguously supported monophyletic lineages makes it highly resilient to potential destabilization caused by the future availability of novel phylogenetic markers and methods. The taxonomic stability is further guaranteed by the modularity of the new termite classification, designed to accommodate as-yet undescribed species with uncertain affinities to the herein delimited monophyletic lineages in the form of new families or subfamilies.

description: Background: An online self-help programme for the treatment of depression called Hap-pas-Hapi was tested among Albanian-speaking immigrants in Switzerland and Germany, and two different levels of cultural adaptation were compared. Despite a massive recruitment effort, an insufficient number of participants could be recruited, and the drop-out rate was over 90%. Aims: We conducted a qualitative study to better understand the reasons for the non-use of Hap-pas-Hapi. Method: Eleven interviews were conducted with 17 Albanian-speaking participants aged 19-59. Participants were recruited for the purpose of this study and were not participants from the trial. They went through the recruitment material and the Hap-pas-Hapi introduction module, commented on the graphic design, usability, content, and shared their views about mental health and self-help. Results: Participants criticised the lack of a “design system” (i.e., a clearly identifiable and consistent graphic design) on social media for Hap-pas-Hapi, and the recruitment messages were unclear. The programme itself was perceived to be important and helpful for the community at large, but most participants said that they would not use it for themselves. The younger generation would have preferred an application in German or French, while the older generation did not see a benefit in using an online self-help programme to manage their psychological distress. Negative beliefs about mental disorders and psychological interventions were perceived to be common in this target group. Discussion: A professional recruitment strategy, a more careful selection of the target population (e.g., age groups) and different kinds of adaptations might have resulted in a better acceptance of the intervention. At the same time, anti-stigma campaigns and psychoeducation are needed to enhance treatment motivation.

description: Social media is increasingly used by humans to express their feelings and opinions in the form of short text messages. Detecting sentiments in the text has a wide range of applications including identifying anxiety or depression of individuals and measuring well-being or mood of a community. Sentiments can be expressed in many ways that can be seen such as facial expression and gestures, speech and by written text. Sentiment Analysis in text documents is essentially a content-based classification problem involving concepts from the domains of Natural Language Processing as well as Machine Learning. In this paper, sentiment recognition based on textual data and the techniques used in sentiment analysis are discussed.

description: Active Galactic Nuclei (AGN) exhibit multi-wavelength properties that are represen- tative of the underlying physical processes taking place in the vicinity of the accreting supermassive black hole. The black hole mass and the accretion rate are fundamen- tal for understanding the growth of black holes, their evolution and the impact on the host galaxies. Recent results on reverberation-mapped AGNs show that highest accretion rate objects have systematic shorter time-lags. These super-Eddington accreting massive black holes (SEAMBHs) show BLR size 3-8 times smaller than predicted by the Radius-Luminosity (R-L) relationship. Hence, the single-epoch virial black hole mass estimates of highly accreting AGNs have an overestimation of a factor of 3-8 times. SEAMBHs likely have a slim accretion disk rather than a thin disk that is diagnostic in X-ray. In this talk, I will present the extreme X-ray properties of a sample of dozen of SEAMBHs. They indeed have steep hard X-ray photon index, Γ, and demonstrate a steeper power-law slope, αox.

description: Resonances of certain light nuclei are explored by studying the complex pole structures of the scattering matrices. Among other results we predict the existence of three-neutron and three-proton resonances, a small spin-orbit splitting in the low-lying He-5 and Li-5 states and the nonexistence of the soft dipole resonance in He-6.

description: Pheidole carrolli Naves
Pheidole carrolli Naves 1985: 58.
types Florida State Collection of Arthropods; Mus. Comp. Zool. Harvard.
Etymology Named after James F. Carroll, collector of part of the type series.
diagnosis A member of the " pilifera complex" of the larger pilifera group; for a characterization of the complex, see under pilifera. Very close to pilifera itself (q.v.), and differing as follows. The only consistent distinction is the orange color of carrolli versus the browns, yellowish browns, and reddish browns of the highly variable, more northern distributed pilifera. In addition the major of carrolli has occiput and dorsal surface of postpetiole completely smooth, but this trait also occurs in some pilifera series.
Measurements (mm) Holotype major: HW 0.56, HL 1.82, SL 0.70, EL 0.24, PW 0.68.
Paratype minor: HW 0.52, HL 0.58, SL 0.54, EL 0.14, PW 0.32.
Color Major: "orange," i.e., concolorous brownish yellow with a slight reddish tinge.
Minor: concolorous yellowish brown, head a slightly darker shade of light brown.
Range Known from Alachua, Citrus, and Leon Counties in northern Florida.
Biology Naves (1985) found carrolli only in the shaded, sandy soil of tall oak or pine woodland. Subsequent collection by Stefan Cover and Lloyd Davis Jr. have securely identified carrolli as an early successional species that occurs in open, often disturbed habitats with sandy soil. Colonies are vigorous and consist of several hundred ants, including several dozen soldiers. Naves' collections may represent moribund colonies in poor nest sites, or colonies about to be eliminated by shading of formerly open habitats. The colonies are small, with only one or two majors present. According to Naves, no more than 15 minors forage at a time, and then singly and mostly at dusk and in the morning, for distances not exceeding 5 meters from the nest entrance. The entrance is difficult to spot and leads to exceptionally deep vertical galleries, in one case extending 1.7 m from the surface. A seedfilled granary chamber approximately 4 X 2 X 2 cm in size is present usually at a depth of 30 cm. The minor workers are exceptionally sluggish, and show the unusual, perhaps unique habit for Pheidole of feigning death when disturbed, often curling themselves around particles of soil in a way that makes them even more difficult to see.

description: Exceptional points (EPs) are degeneracies in open wave systems with coalescence of at least two energy levels and their corresponding eigenstates. In higher dimensions, more complex EP physics not found in two-state systems is observed. We consider the emergence and interaction of multiple EPs in a four coupled optical waveguides system by non-Hermitian coupling showing a unique EP formation pattern in a phase diagram. In addition, absolute phase rigidities are computed to show the mixing of the different states in definite parameter regimes. Our results could be potentially important for developing further understanding of EP physics in higher dimensions via generalized paradigm of nonHermitian coupling for a new generation of parity-time (PT) devices.

description: Background: Research on cultural adaptation of psychological interventions indicates that a higher level of adaptation is associated with a higher effect size of the intervention. However, direct comparisons of different levels of adaptations are scarce. Aims: This study used a smartphone-based self-help programme called Step-by-Step (Albanian: Hap-pas-Hapi) for the treatment of psychological distress among Albanian-speaking immigrants in Switzerland and Germany. Two levels of cultural adaptation (i.e., surface vs. deep structure adaptation) were compared. We hypothesised that the deep structure adaptation would enhance the acceptance and efficacy of the intervention. Method: We conducted a two-arm, single-blind randomised controlled trial. Inclusion criteria were good command of the Albanian language, age above 18, and elevated psychological distress (Kessler Psychological Distress Scale score above 15). Primary outcome measures were the total score of the Hopkins Symptom Checklist and the number of participants who completed at least three (out of five) sessions. Secondary outcomes were global functioning, well-being, post-traumatic stress, and self-defined problems. Results: Two-hundred-twenty-two participants were included, of which 18 (8%) completed the post-assessments. The number of participants who completed the third session was equal in both conditions, with N = 5 (5%) and N = 6 (6%) respectively. Discussion: Drop-out rates were high in both conditions, and no group difference was found regarding the acceptance of the intervention. The high drop-out rate stands in contrast with other trials testing Step-by-Step. Future research should examine cultural factors impacting recruitment strategies, as insights could help to reduce participant drop-out rates in clinical trials.

description: Energy and momentum conservation in the context of a type II, purely transmitting, defect, within a single scalar relativistic two-dimensional field theory, places a severe constraint not only on the nature of the defect but also on the potentials for the scalar fields to either side of it. The constraint is of an unfamiliar type since it requires the Poisson Bracket of the defect contributions to energy and momentum with respect to the defect discontinuity and its conjugate to be balanced by the potential difference across the defect. It is shown that the only solutions to the constraint correspond to the known integrable field theories.

The direction of RecA protein assembly onto single strand DNA is the same as the direction of strand assimilation during strand exchange.

description: The RecA protein of Escherichia coli optimally promotes DNA strand exchange reactions in the presence of the single strand DNA-binding protein of E. coli (SSB protein). Under these conditions, assembly of RecA protein onto single-stranded DNA (ssDNA) occurs in three steps. First, the ssDNA is rapidly covered by SSB protein. The binding of RecA protein is then initiated by nucleation of a short tract of RecA protein onto the ssDNA. Finally, cooperative polymerization of additional RecA protein accompanied by displacement of SSB protein results in a ssDNA-RecA protein filament (Griffith, J. D., Harris, L. D., and Register, J. C. (1984) Cold Spring Harbor Symp. Quant. Biol. 49, 553-559). We report here that RecA protein assembly onto circular ssDNA yields RecA protein-covered circles in which greater than 85% are completely covered by RecA protein with no remaining SSB protein-covered segments (as detected by electron microscopy). However, when linear ssDNA is used, 90% of the filaments contain a short segment at one end complexed with SSB protein. This suggests that RecA protein assembly is unidirectional. Visualization of the assembly of RecA protein onto either long ssDNA tails (containing either 5' or 3' termini) or ssDNA gaps generated in double strand DNA allowed us to determine that the RecA protein polymerizes in the 5' to 3' direction on ssDNA and preferentially nucleates at ssDNA-double strand DNA junctions containing 5' termini.

description: We report scanning tunneling microscopy (STM) images of surfaces of GaN films and the observation of luminescence from those films induced by highly spatially localized injection of electrons or holes using STM. This combination of scanning tunneling luminescence (STL) with STM for GaN surfaces and the ability to observe both morphology and luminescence in GaN is the first step to investigate possible correlations between surface morphology and optical properties.

description: We study how effects of the CP violation can be observed indirectly by precision measurements of Higgs boson couplings at a future Higgs factory such as the international linear collider. We consider two Higgs doublet models with the softly broken discrete symmetry. We find that by measuring the Higgs boson couplings very precisely we are able to distinguish the two Higgs doublet model with CP violation from the CP conserving one.
