description: Polarized continuum emission from aligned grains in disks around young stellar objects can be used to probe the magnetic field, radiation anisotropy, or drift between dust and gas, depending on whether the non-spherical grains are aligned magnetically, radiatively or mechanically. We show that it can also be used to probe another key disk property -- the temperature gradient -- along sight lines that are optically thick, independent of the grain alignment mechanism. We first illustrate the technique analytically using a simple 1D slab model, which yields an approximate formula that relates the polarization fraction to the temperature gradient with respect to the optical depth tau at the tau=1 surface. The formula is then validated using models of stellar irradiated disks with and without accretion heating. The promises and challenges of the technique are illustrated with a number of Class 0 and I disks with ALMA dust polarization data, including NGC 1333 IRAS4A1, IRAS 16293B, BHB 07-11, L1527, HH 212 and HH 111. We find, in particular, that the sight lines passing through the near-side of a highly inclined disk trace different temperature gradient directions than those through the far-side, which can lead to a polarization orientation on the near-side that is orthogonal to that on the far-side, and that the HH 111 disk may be such a case. Our technique for probing the disk temperature gradient through dust polarization can complement other methods, particularly those using molecular lines.

description: Seed shattering, i.e., the loss of seeds at ripening stage shortly before or during seed harvest, is strongly reducing seed yield in Italian ryegrass (Lolium multiflorum Lam.). The aim of this study was to evaluate the possibility to reduce seed shattering within breeding germplasm via recurrent phenotypic selection on spaced plants. Starting from a founder population of 300 plants serving as F0 population, two cycles of phenotypic selection for high and low seed shattering were applied and compared to randomly selected individuals on spaced plant level and in plot trials. Comparison of the five resulting populations in a spaced plant trial revealed a significant effect of selection, with lowest seed shattering (15.3%) observed in the population selected twice for decreased shattering (15.3%) and highest seed shattering (47.9%) for the population selected twice for increased shattering. The same ranking of the five F2 populations was observed in a subsequent trial with sown plots. Thus, using the method presented here, recurrent selection on single spaced plants allows to efficiently reduce seed shattering and, therefore, to increase seed yield in swards.

description: Chemical investigation of the marine-derived endophytic fungus Ascomycota sp. VK12 resulted in isolation and identification of a new compound, (3R)-(3′,5′-dihydroxyphenyl)butan-2-one (1) and five known ones: AGI-7 (2), sescandelin (3), sescandelin-B (4), 4-hydroxybenzaldehyde (5), and hydroxysydonic acid (6). The absolute configuration of 1 was determined by time-dependent density functional theory electronic circular dichroism, specific optical rotation, and NMR calculations. Compounds 1 and 2 showed cytotoxicity towards HepG2, MCF-7, and SK-Mel2 carcinoma cells, with IC50 values ranging from 48.6 to 96.5 µM. Compounds 1, 2, 4–6 displayed NO inhibitory effects in LPS-stimulated BV2 cells, with IC50 values in a range from 24.2 to 76.5 µM. Compound 2 further inhibited PGE2 overproduction, with an IC50 value of 25.3 µM. The inhibitory effects of 2 towards NO and PGE2 overproduction were found to have a close relationship with its suppression of iNOS and COX-2 protein expression, respectively.

description: Responding to user reviews promptly and satisfactorily improves application ratings, which is key to application popularity and success. The proliferation of such reviews makes it virtually impossible for developers to keep up with responding manually. To address this challenge, recent work has shown the possibility of automatic response generation. However, because the training review-response pairs are aggregated from many different apps, it remains challenging for such models to generate app-specific responses, which, on the other hand, are often desirable as apps have different features and concerns. Solving the challenge by simply building a model per app (i.e., training with review-response pairs of a single app) may be insufficient because individual apps have limited review-response pairs, and such pairs typically lack the relevant information needed to respond to a new review. To enable app-specific response generation, this work proposes AARSynth: an app-aware response synthesis system. The key idea behind AARSynth is to augment the seq2seq model with information specific to a given app. Given a new user review, it first retrieves the top-K most relevant app reviews and the most relevant snippet from the app description. The retrieved information and the new user review are then fed into a fused machine learning model that integrates the seq2seq model with a machine reading comprehension model. The latter helps digest the retrieved reviews and app description. Finally, the fused model generates a response that is customized to the given app. We evaluated AARSynth using a large corpus of reviews and responses from Google Play. The results show that AARSynth outperforms the state-of-the-art system by 22.2% on BLEU-4 score. Furthermore, our human study shows that AARSynth produces a statistically significant improvement in response quality compared to the state-of-the-art system.

description: In high energy physics, a widely used method to treat systematic uncertainties in confidence interval calculations is based on combining a frequentist construction of confidence belts with a Bayesian treatment of systematic uncertainties. In this note we present a study of the coverage of this method for the standard Likelihood Ratio (aka Feldman & Cousins) construction for a Poisson process with known background and Gaussian or log-Normal distributed uncertainties in the background or signal efficiency. For uncertainties in the signal efficiency of upto 40 % we find over-coverage on the level of 2 to 4 % depending on the size of uncertainties and the region in signal space. Uncertainties in the background generally have smaller effect on the coverage. A considerable smoothing of the coverage curves is observed. A software package is presented which allows fast calculation of the confidence intervals for a variety of assumptions on shape and size of systematic uncertainties for different nuisance parameters. The calculation speed allows experimenters to test the coverage for their specific conditions.

description: This thesis analyzes the scientific foundations of Jadid pedagogy within the framework of foreign studies on education. The main principles of the pedagogy of the Jadid movement, its place in the modern education system and how it is reflected in the studies of foreign scientists are studied. In particular, the advanced approaches of Jadid pedagogy, which were formed in Central Asia at the beginning of the 20th century, as well as the views of Western and Eastern researchers on this issue, are comparatively analyzed. The results of the study serve to draw conclusions about the impact of Jadid pedagogy on the current educational process and its relevance.

description: The collective dynamics of liquid Gallium close to the melting point has been studied using Inelastic X-ray Scattering to probe lengthscales smaller than the size of the first coordination shell. %(momentum transfers, $Q$, $>$15 nm$^{-1}$). Although the structural properties of this partially covalent liquid strongly deviate from a simple hard-sphere model, the dynamics, as reflected in the quasi-elastic scattering, are beautifully described within the framework of the extended heat mode approximation of Enskog's kinetic theory, analytically derived for a hard spheres system. The present work demonstrates the applicability of Enskog's theory to non hard- sphere and non simple liquids.

description: In this work, we study the presence of hurricanes on exoplanets. Tidally locked terrestrial planets around M dwarfs are the main targets of space missions looking to discover habitable exoplanets. The question of whether hurricanes can form on this kind of planet is important for determining their climate and habitability. Using a high-resolution global atmospheric circulation model, we investigated whether there are hurricanes on tidally locked terrestrial planets under fixed surface temperatures. The relevant effects of the planetary rotation rate, surface temperature, and bulk atmospheric compositions were examined. We find that hurricanes can form on the planets but not on all of them. For planets near the inner edge of the habitable zone of late M dwarfs, there are more numerous and stronger hurricanes on both day and night sides. For planets in the middle and outer ranges of the habitable zone, the possibility of hurricane formation is low or even close to zero, as has been suggested in recent studies. Earth-based hurricane theories are applicable to tidally locked planets only when the atmospheric compositions are similar to that of Earth. However, if the background atmosphere is lighter than H2O, hurricanes can hardly be produced because convection is always inhibited due to the effect of the mean molecular weight, similarly to the case of Saturn. These results have broad implications on the precipitation, ocean mixing, climate, and atmospheric characterization of tidally locked planets. Finally, A test with a coupled slab ocean and an Earth-like atmosphere in a tide-locked orbit of ten Earth days demonstrates that there are also hurricanes present in the experiment.

description: This paper uses microlevel data from the Agricultural Resource Management Survey to examine the changes in the distributions of household wealth and to assess the role farm subsidies play, among other factors, in affecting these distributions. The empirical analysis relies on the concept of the adjusted Gini coefficient and on fixed-effect regression procedures. Coefficients from fixed-effect estimation indicate a negative correlation between government payments and wealth dispersion, with the effect shifting toward more of a positive relation when government payments were allowed to interact with regional dummies.

description: Theories of $f(T)$ gravity are being actively confronted with cosmological observations, and are being studied for their potential to solve famous problems of cosmology. A necessary step is to extend these studies to astrophysical settings. However, to this end one must understand the structure of spherically symmetric solutions. We show that two different known approaches to these solutions are actually fully equivalent from the point of view of Lorentz-covariant formalism. Moreover, we explain Bianchi identities in $f(T)$ gravity and apply them to show that the corresponding equations are always compatible. It puts these efforts on much firmer grounds than before.

description: Do cost considerations justify the current structure of production of extension services in which one or more providers exists in virtually all of the contiguous U.S. states? Provision of extension services has sizable cost implications for the host institutions. Yet, to our knowledge, there has been virtually no analysis of the impact of extension on higher education costs. Using academic year 1995-1996 data, we estimate a multiproduct cost function for 1,445 public institutions of higher education in the United States, including 65 that provide extension services. We find evidence of significant economies of scale with respect to the provision of extension services but no evidence of significant economies of scope between the provision of extension and the production of research, undergraduate education, or graduate education.

New Results in Light-Front Phenomenology
Creators: name: Brodsky, S. J.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The light-front quantization of gauge theories such as QCD in light-cone gauge provides a frame-independent wavefunction representation of relativistic bound states, simple forms for current matrix elements, explicit unitarity, and a trivial vacuum. The freedom to choose the light-like quantization four-vector provides an explicitly covariant formulation of light-front quantization and can be used to determine the analytic structure of light-front wave functions and to define a kinematical definition of angular momentum. The AdS/CFT correspondence of large $N_C$ supergravity theory in higher-dimensional anti-de Sitter space with supersymmetric QCD in 4-dimensional space-time has interesting implications for hadron phenomenology in the conformal limit, including an all-orders demonstration of counting rules for exclusive processes. String/gauge duality also predicts the QCD power-law behavior of light-front Fock-state hadronic wavefunctions with arbitrary orbital angular momentum at high momentum transfer. The form of these near-conformal wavefunctions can be used as an initial ansatz for a variational treatment of the light-front QCD Hamiltonian. I also briefly review recent analyses which shows that some leading-twist phenomena such as the diffractive component of deep inelastic scattering, single-spin asymmetries, nuclear shadowing and antishadowing cannot be computed from the LFWFs of hadrons in isolation.

Recent research has developed two empirically successful calibrations to remove hypothetical bias, though the calibrations have not been tested using the same data or in a conjoint analysis. This study compares the two calibrations in a conjoint analysis involving donations to a public good. Results find the calibrations are biased predictors of true donations but that calibrated and uncalibrated models together provide upper and lower bounds to true donations.

description: In this paper we present a generalization of Poincaré's Rotation Theory of homeomorphisms of the circle to the case of one-dimensional compact abelian groups which are solenoidal groups, {\it i.e.}, groups which fiber over the circle with fiber a Cantor abelian group. We define rotation elements, \emph{à la} Poincaré and discuss the dynamical properties of translations on these solenoidal groups. We also study the semiconjugation problem when the rotation element generates a dense subgroup of the solenoidal group. Finally, we comment on the relation between Rotation Theory and entropy for these homeomorphisms, since unlike the case of the circle, for the solenoids considered here there are homeomorphisms (not homotopic to the identity) with positive entropy.

A considerable modification of the thermodynamical variables temperature, flow-velocity, energy density and particle density has been found. Due to the nucleon mass shift the freeze out particle distribution functions are changed noticeably in comparison with evaluations, which use vacuum nucleon mass.

description: Harvest timeliness is a continual problem in rotation of cotton and peanuts. Efficient allocation of land and labor resources during production of cotton and peanuts requires decisions be made on allocating resources throughout the growing season. Of particular concern is efficient allocation during planting and harvesting. Through economic analysis and linear programming optimization, planting and harvesting timeliness issues are addressed and compared with prevailing practices. Results for a representative farm indicate that cotton planting should increase during the early period of the planting season as compared with current practice, and most cotton should be harvested before peanut harvest begins.
A class of equations with peakon and pulson solutions (with an Appendix by Harry Braden and John Byatt-Smith)

description: We consider a family of integro-differential equations depending upon a parameter $b$ as well as a symmetric integral kernel $g(x)$. When $b=2$ and $g$ is the peakon kernel (i.e. $g(x)=\exp(-|x|)$ up to rescaling) the dispersionless Camassa-Holm equation results, while the Degasperis-Procesi equation is obtained from the peakon kernel with $b=3$. Although these two cases are integrable, generically the corresponding integro-PDE is non-integrable. However,for $b=2$ the family restricts to the pulson family of Fringer & Holm, which is Hamiltonian and numerically displays elastic scattering of pulses. On the other hand, for arbitrary $b$ it is still possible to construct a nonlocal Hamiltonian structure provided that $g$ is the peakon kernel or one of its degenerations: we present a proof of this fact using an associated functional equation for the skew-symmetric antiderivative of $g$. The nonlocal bracket reduces to a non-canonical Poisson bracket for the peakon dynamical system, for any value of $b\neq 1$.

description: The issue of whether vertical integration can raise market power is hotly debated because firms have a market power-related incentive to integrate vertically. Using a sample of U.S. food manufacturing industries, this “market power” motive is empirically tested in this study. Empirical analysis shows that forward vertical ownership integration (or vertical mergers) did not increase food manufacturers’ market power in the final product market. The study, however, shows that both market structure and conduct significantly influenced market power in the food industries.

Isolation of endophytic bacteria from Lodgepole Pine (Pinus contorta var. latifolia (Dougl.) Engelm.) and Western Red Cedar (Thuja plicata Donn.) and determination of their nitrogen fixing ability

description: The diversity of endophytic bacteria in lodgepole pine and western red cedar tissues and whether endophytic diazotrophs isolated from these tissues were capable of supplying biologically significant amounts of fixed nitrogen to these two species were examined. Plant samples were collected from stands in central and southern British Columbia and endophytic bacteria were isolated primarily from stem tissues using a surface sterilization-trituration-plating technique. Most of the endophytic bacteria isolated from pine and cedar tissues belonged to the genera Bacillus and Paenibacillus. The N-fixing ability of isolates was tested using an acetylene reduction assay. Four isolates capable of reducing acetylene were selected to determine their ability to provide biologically significant amounts of fixed N to pine and cedar seedlings in two separate controlled environment experiments. This included Paenibacillus amylolyticus C3b, rifamycin-resistant derivatives of P. peoriae/polymyxa P2b and P18b, and a rifamycin-resistant derivative of strain P19a, which was closely related to Dyadobacter fermentans. Surface sterilized pine and cedar seeds were sown separately in glass tubes containing an autoclaved mixture of sand and montmorillonite clay treated with a nutrient solution having a ¹⁵N label. Each tube was then inoculated with ca. 10⁷ cfu of one of strains P2b-2R, P18b-2R, P19a-2R, orC3b. The only treatment in which seedlings had significantly lower atom % ¹⁵N excess values in foliage than in control seedlings in both plant growth trials for cedar and pine was the P2b-2R treatment. Inoculation of seed with strain P2b-2R resulted in cedar and pine seedlings harvested 35 and 42 weeks, respectively, after sowing, deriving as much as 56% and 66%, respectively, of their foliar N from the atmosphere. Pine seedlings from the C3b and P18b-2R treatments from only the first trial derived less significant quantities of foliar N from the atmosphere. Strain P19a-2R did not provide significant amounts of fixed N to cedar and pine seedlings in either trial. Despite cedar and pine seedlings from the P2b-2R treatments deriving significant amounts of fixed N, increases in foliar N content were not common and growth of seedlings of both species was depressed. Strain P2b-2R could be readily isolated from rhizosphere samples following both seedling harvests for cedar and pine. However endophytic colonization of tissues by this strain could not be confirmed due to persistent contamination on imprint plates used to determine the effectiveness of the tissue surface sterilization techniques employed.

description: Modeling visual search not only offers an opportunity to predict the usability of an interface before actually testing it on real users, but also advances scientific understanding about human behavior. In this work, we first conduct a set of analyses on a large-scale dataset of visual search tasks on realistic webpages. We then present a deep neural network that learns to predict the scannability of webpage content, i.e., how easy it is for a user to find a specific target. Our model leverages both heuristic-based features such as target size and unstructured features such as raw image pixels. This approach allows us to model complex interactions that might be involved in a realistic visual search task, which can not be easily achieved by traditional analytical models. We analyze the model behavior to offer our insights into how the salience map learned by the model aligns with human intuition and how the learned semantic representation of each target type relates to its visual search performance.

The calculated cross section upper limit is $\sim 40$ fb for the 4 muons channel, and $\sim 28$ nb for the $D^{(*)} \bar D^{(*)} \to eμ$ channel. On the basis of our results, with the present sensitivity LHCb should detect both signals, for $0^{++}$ and $2^{++}$ fully-charmed tetraquarks.

description: Long-distance mobility sustainability, high-speed railways (HSR) decarbonization effect, and bans for short-haul flights are debated in Europe. Yet, holistic environmental assessments on these topics are scarce. A comparative life cycle assessment (LCA) was conducted on the Paris-Bordeaux transportation options in France: HSR, plane, coach, personal car, and carpooling. The overall ranking on four environmental indicators, from best to worst, is as follows: coach, HSR, carpooling, private car, and plane. Scenario analyses showed that increasing train occupancy decreases the environmental impact of the mode (-12%), while decreasing speed does not. Moreover, worldwide carbon footprints of electric HSR modes range 30-120 gCO2eq per passenger-kilometer traveled. Finally, a consequential LCA highlighted carbon paybacks of the HSR project. Under a business-as-usual trip substitution scenario, the HSR gets net-zero 60 years after construction. With a short-haul flight ban, it occurs after 10 years. This advocates for generalizing short-haul flight bans and investing in HSR infrastructure.

description: The polarization density matrix formalism is employed to include the final lepton mass and spin into the popular model by Rein and Sehgal for single pion neutrinoproduction. We investigate the effect of the $τ$ lepton mass on the differential cross sections. The lepton polarization evaluated within the extended RS model is compared against that follows from the single resonance production model based upon the Rarita-Schwinger formalism with phenomenological transition form factors.

description: Within the framework of the modified potential cluster model with forbidden states and their classification according to Young diagrams, the possibility of describing experimental data on the total cross sections of the neutron radiative capture on 7Li is considered. It is shown that the model used and the methods for constructing potentials make it possible to correctly describe the behavior of experimental cross sections at energies of 5 meV (5 10-3 eV) to 1 MeV(1 10+6 eV), where experimental data are available. Based on the obtained total cross sections up to 5 MeV, the reaction rate was calculated and its analytical approximation was carried out. It was shown that the 7Li(n,g)8Li reaction dominates at T9 < 0.1-0.2 as against with the burning of 7Li in reactions 7Li(3H,n)9Be and 7Li(4He,g)11B.

description: We present a model describing the temporal evolution of opinions due to interactions among a network of individuals. This Accept-Shift-Constrict (ASC) model is formulated in terms of coupled nonlinear differential equations for opinions and uncertainties. The ASC model dynamics allows for the emergence and persistence of majority positions so that the mean opinion can shift even for a symmetric network. The model also formulates a distinction between opinion and rhetoric in accordance with a recently proposed theory of the group polarization effect. This enables the modeling of discussion-induced shifts toward the extreme without the typical modeling assumption of greater resistance to persuasion among extremists. An experiment is described in which triads engaged in online discussion. Simulations show that the ASC model is in qualitative and quantitative agreement with the experimental data.

description: Farm financial structure may affect both short- and long-run input usage, thereby affecting farm efficiency. Any inefficiencies arising from the choice of inputs can be magnified over time as credit constraints continue to affect input usage. In a panel of 54 North Dakota crop farms, efficiency and debt structure were related. Intermediate debt was found to be positively related to farm technical efficiency, and short-term debt was negatively associated with technical efficiency. Use of intermediate-term debt was positively associated with farm-scale efficiency, whereas no significant relationship was found between short- and long-term debt and scale efficiency.

description: A characterisation of the quantum stochastic bounded generators of irreversible quantum state evolutions is given. This suggests the general form of quantum stochastic evolution equation with respect to the Poisson (jumps), Wiener (diffusion) or general Quantum Noise. The corresponding irreversible Heisenberg evolution in terms of stochastic completely positive (CP) cocycles is also characterized and the general form of the stochastic completely dissipative (CD) operator equation is discovered.

description: To cope with the rapid growth in available data, the efficiency of data analysis and machine learning libraries has recently received increased attention. Although great advancements have been made in traditional array-based computations, most are limited by the resources available on a single computation node. Consequently, novel approaches must be made to exploit distributed resources, e.g. distributed memory architectures. To this end, we introduce HeAT, an array-based numerical programming framework for large-scale parallel processing with an easy-to-use NumPy-like API. HeAT utilizes PyTorch as a node-local eager execution engine and distributes the workload on arbitrarily large high-performance computing systems via MPI. It provides both low-level array computations, as well as assorted higher-level algorithms. With HeAT, it is possible for a NumPy user to take full advantage of their available resources, significantly lowering the barrier to distributed data analysis. When compared to similar frameworks, HeAT achieves speedups of up to two orders of magnitude.

description: Environment modeling utilizing sensor data fusion and object tracking is crucial for safe automated driving. In recent years, the classical occupancy grid map approach, which assumes a static environment, has been extended to dynamic occupancy grid maps, which maintain the possibility of a low-level data fusion while also estimating the position and velocity distribution of the dynamic local environment. This paper presents the further development of a previous approach. To the best of the author's knowledge, there is no publication about dynamic occupancy grid mapping with subsequent analysis based only on radar data. Therefore in this work, the data of multiple radar sensors are fused, and a grid-based object tracking and mapping method is applied. Subsequently, the clustering of dynamic areas provides high-level object information. For comparison, also a lidar-based method is developed. The approach is evaluated qualitatively and quantitatively with real-world data from a moving vehicle in urban environments. The evaluation illustrates the advantages of the radar-based dynamic occupancy grid map, considering different comparison metrics.

The accretion and spreading of matter on white dwarfs

description: For a slowly rotating non-magnetized white dwarf the accretion disk extends all the way to the star. Here the matter impacts and spreads towards the poles as new matter continuously piles up behind it. We have solved the 3d compressible Navier-Stokes equations on an axisymmetric grid to determine the structure of this boundary layer for different viscosities corresponding to different accretion rates. The high viscosity cases show a spreading BL which sets off a gravity wave in the surface matter. The accretion flow moves supersonically over the cusp making it susceptible to the rapid development of gravity wave and/or Kelvin-Helmholtz instabilities. This BL is optically thick and extends more than 30 degrees to either side of the disk plane after 3/4 of a Keplerian rotation period (t=19s). The low viscosity cases also show a spreading BL, but here the accretion flow does not set off gravity waves and it is optically thin.

description: Cordyceps sinensis is a traditional Chinese medicine with various biological activities. With its limited natural supply, cultured C. militaris has become the major alternative source, and the culture conditions may affect the chemical compositions. To improve the production of chemical ingredients, C. militaris was cultured with three different media, including rice only, rice plus 3% tea leaves, and rice plus 3% droppings of Andraca theae. The fractions of dried C. militaris cultured with rice were chromatographic separated to afford ten compounds: phenylalanine, dimerumic acid, nicotinic acid, tryptophan, N6-(2-hydroxyethyl)-adenosine, uracil, uridine, cordycepin, ergosterol, and mannitol. Of these, in the cultured medium of rice plus 3% Andraca droppings, the amount of one major compound cordycepin is about two folds than the highest reported data, and dimerumic acid and N6-(2-hydroxyethyl)-adenosine were isolated for the first time from this species.

description: The recent lumber trade war between Canada and the United States deals with Canadian stumpage policies, Canada’s log export controls, and U.S. retaliatory duty. This study determines the appropriate level of U.S. countervailing duty (CVD) by employing a vertically interrelated log–lumber model. The theoretical results show that the U.S. CVD can be greater (will be less) than the Canadian subsidy for a vertically related log–lumbermarket (for lumber market only). Empirical results support the theoretical findings in that the U.S. CVD for the log–lumber market (lumber market alone) is 1.55 (0.91) times the Canadian subsidy.
