description: There are some discrepancies in the results on energy spectrum from Yakutsk, AGASA, and HiRes experiments. In this work differential energy spectrum of primary cosmic rays based on the Yakutsk EAS Array data is presented. For the largest events values of $S_{600}$ and axes coordinates have been obtained using revised lateral distribution function. Simulation of converter's response at large distances showed no considerable underestimation of particle density. Complex shape of spectrum in region of $\E > 10^{17}$ eV is confirmed. After adjustment of parameters and additional exposition at the Yakutsk array there are three events with energy $\E > 10^{20}$ eV.

description: Agriculture in the Texas High Plains depends entirely on the Ogallala Aquifer. Texas enacted water conservation legislation to address declining reserves in the aquifer. We developed an integrated regional water policy model that links a hydrology model with an economic optimization model to estimate policy impacts with respect to economic cost and water conservation. Testing the effectiveness of two policies, a groundwater extraction tax and extraction quotas, we observe that neither significantly inhibits groundwater use. Although both policies conserve similar amounts of groundwater, the regional cost of the tax policy to agriculture is more than the quota policy.

description: Trajectory planning at high velocities and at the handling limits is a challenging task. In order to cope with the requirements of a race scenario, we propose a far-sighted two step, multi-layered graph-based trajectory planner, capable to run with speeds up to 212~km/h. The planner is designed to generate an action set of multiple drivable trajectories, allowing an adjacent behavior planner to pick the most appropriate action for the global state in the scene. This method serves objectives such as race line tracking, following, stopping, overtaking and a velocity profile which enables a handling of the vehicle at the limit of friction. Thereby, it provides a high update rate, a far planning horizon and solutions to non-convex scenarios. The capabilities of the proposed method are demonstrated in simulation and on a real race vehicle.

description: The U.S. crop subsidies provide incentives for farmers to expand feedstock production, which benefits the biofuel producers by lowering input costs. This study develops a general equilibrium model to analyze the effects of a reduction in the U.S. crop subsidy on biofuel industries and social welfare. The impacts of feedstock policies on the biofuel market are marginal. In contrast, the biofuel mandate has a larger impact and counteracts the effects of the crop subsidy reduction. The mandate increases the demand for feedstock and causes not only grain ethanol, but also cellulosic ethanol production to rise. The mandate exacerbates the distortion, and government spending increases significantly, leading to greater welfare loss.
Effect of nonmagnetic and magnetic impurities on the specific heat jump in anisotropic superconductors

description: The specific-heat jump $ΔC$ at a critical temperature $T_c$ in an anisotropic superconductor containing both potential and spin-flip scatterers is calculated within a weak-coupling mean-field approximation. It is shown that the presence of even a small amount of spin-flip scatterers in the sample leads to a drastic change in the dependence of $ΔC$ on $T_c$ in a disordered $(d+s)$-wave or a strongly anisotropic s-wave superconductor. The implications for experimental tests for the presence of an s-wave admixture in the superconducting order parameter of high-$T_c$ superconductors are discussed.

description: We present the results obtained from a detailed X-ray timing and spectral analysis of Seyfert 2 galaxy NGC 6300 by using observations with the {\it Suzaku}, {\it Chandra} and {\it NuSTAR} observatories between 2007 and 2016. We calculate variance, rms fractional variability of the source in different energy bands and find variabilities in various energy bands. Spectral properties of the source are studied by using various phenomenological and physical models. The properties of the Compton clouds, reflection, Fe K$α$ line emission and soft X-ray excess are studied in detail. Several physical parameters of the source are extracted and investigated to establish the presence/absence of any correlation between them. We also investigate the nature of the circumnuclear `torus' and find that the torus is not uniform, rather clumpy. The observed changes in the line-of-sight column density can be explained in terms of transiting clouds. The iron line emitting region is found to be different in the different epoch of observations. We also observe that the torus and the nucleus independently evolve over the years.

Data-determined historical decompositions were conducted to provide a weekly picture of domestic shipment, import, and price fluctuation transmissions. The empirical analysis based on a vector autoregression (VAR) model showed differences in the results depending on the source of the outbreak (domestic vs. imported).
Development of a proteomic approach for identifying protein-protein interactions
Creators: name: Vasilescu, Julian
Publisher: name: University of British Columbia
Year: 2009

description: The purification of protein complexes can be accomplished by different types of affinity chromatography. In a typical immunoaffinity experiment, protein complexes are captured from a cell lysate by an immobilized antibody that recognizes an epitope on one of the known components of the complex. After extensive washing to remove unspecifically bound proteins, the complexes are eluted and analyzed by mass spectrometry. Transient protein complexes, which are characterized by high dissociation constants, are typically lost by this approach. The primary objective of this study is to describe a novel method for identifying transient protein-protein interactions using a combination of in vivo cross-linking, immunoaffinity purification, and mass spectrometry-based protein identification. Live cells expressing an epitope-tagged protein of interest are treated with formaldehyde, which rapidly permeates the cell membrane and generates protein-protein cross-links. Proteins cross-linked to the protein of interest are co-purified by immunoaffinity chromatography and subjected to a procedure which dissociates the cross-linked complexes. After separation by sodium dodecyl sulfate polyacrylamide gel electrophoresis, interacting proteins are identified by mass spectrometry. Application of this method enabled the identification of numerous proteins that co-purified with a constitutively active form of a Ras GTPase known as M-Ras (MRasQ71L), which was stably expressed in the murine mast cell line R6X. Among the proteins that were co-purified, the RasGAP-related protein IQGAP1 was shown to be a novel interaction partner of M-RasQ71L. We believe that this method is applicable to many proteins and will prove to be a valuable tool for the study of protein-protein interactions.

To begin with, inclusion of zero mass particle in mechanics leads to special relativity while its interaction with a universal force shared by all particles leads to general relativity. The universal nature of force further suggests that it is intrinsically attractive, self interactive and higher dimensional. I argue that the principle of universality could serve as a good guide for future directions.

description: Many economists and others are interested in the phenomenon of rising alcohol content of wine and its potential causes. Has the alcohol content of wine risen—and if so, by how much, where, and when? What roles have been played by climate change and other environmental factors compared with evolving consumer preferences and expert ratings? In this paper we explore these questions using international evidence, combining time-series data on the alcohol content of wine from a large number of countries that experienced different patterns of climate change and influences of policy and demand shifts. We also examine the relationship between the actual alcohol content of wine and the alcohol content stated on the label. The systematic patterns here suggest that rising alcohol content of wine may be a nuisance by-product of producer responses to perceived market preferences for wines having riper, more-intense flavors, possibly in conjunction with evolving climate.

description: Many communities in the United States face the decision about whether to protect or restore forests on environmentally sensitive sites. The objective of this research is to identify priority areas for forest landscape restoration in Knox County, Tennessee. A cost-benefit analysis is conducted to determine individuals’ willingness to accept reforestation as a substitute for other potential land uses, given the explicit costs and benefits of reforestation. A sequence of hedonic models is used to estimate differences in values attached to housing prices of multiple potential sites for restoration projects values. This approach allows the establishment of an overall price-distance relationship between the amenity values attributable to both deforested and forested areas and their proximities to housing locations within the county. Based on the overall price-distance relationship, the sum of the differences between amenity values of deforested and forested areas is estimated, as reflected in housing prices across different proximities to potential restoration sites. The results of this study show that there are potentially great gains to the community through reforestation projects but those benefits can vary greatly depending on the acreages of potential target sites, the number of houses in the surrounding area, and the proximity of houses surrounding the site.

description: This study analyses potential adverse effects of unilateral increase in GHG emission standards. The single good two regions partial equilibrium model of international trade is used to derive and interpret the conditions under which such an increase will lead to a reduction in a total level of GHG emission. We found that improvement in the global GHG emission level will be observed if the response of the home country abatement level is more elastic than that of the foreign country by the factor of the ratio of initial foreign to domestic marginal emission intensities. It is also shown that in the large industry case, the appropriate factor is adjusted by the measure of the relative market influence of two industries. The study concludes that a unilateral reduction in GHG emissions will unlikely lead to the reduction in the total GHG emissions level and may worsen the environmental situation in other regions. An appropriate multilateral agreement that involves producers from the major emitting countries is required to achieve the goal.

description: The quasi-one-dimensional helimagnet LiCu2O2 was studied by single crystal inelastic neutron scattering. The dispersion relation of spin wave excitations was measured in the vicinity of the principal magnetic Bragg reflection. A spin wave theoretical analysis of the data yields an estimate of the relevant exchange constants and explains the mechanism of geometric frustration that leads to helimagnetism. It is found that the simple antiferromagnetic J_1-J_2 model that was previously proposed is inadequate for LiCu2O2. The experimental findings are generally in a qualitative agreement with first principal calculations of [A. A. Gippius et al., Phys. Rev.

Abstract:

In everyday life, listeners are often confronted with situations in which multiple talkers speak simultaneously. Those so-called cocktail-party situations can be static, that is, the target talker always remains the same, or they can be dynamic, meaning the target talker changes in an unpredictable manner. Previous studies have shown that, in dynamic situations, the listener’s speech intelligibility often decreases after a transition from one target talker to the other. Afterwards it takes some time until the speech intelligibility is back to its initial state again. This study examined which factors contribute to the drop in speech intelligibility after a transition. To this end, a setup involving three competing talkers uttering matrix sentences was used (cf. Meister et al., this conference). The talkers differed in terms of their voices (medium male, deep female and high female) and spatial positions (-60°, 0° and +60° azimuth angle). The target talker was unknown to the listeners in advance and was indicated by the first word of the sentence. Depending on the condition, target talkers changed either after each trial (transition probability = 100%) or only in 20% of the trials. Two different transition types were used: 1) The talkers either remained at the same positions and the target voice changed; 2) the talkers switched positions but the target voice remained the same. Fourteen younger normal-hearing and 18 older normal-hearing listeners participated in the study.This poster will present an analysis of the influence of different factors on speech intelligibility after transitions. These factors include the target talker position, the transition probability and the individual hearing thresholds. Furthermore, we will address the question of how fast listeners were able to switch attention from one talker to the other.Funding: Supported by Deutsche Forschungsgemeinschaft (ME2751/3-1).
Flutter and resonances of a flag near a free surface

Year: 2020
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We investigate the effects of a nearby free surface on the stability of a flexible plate in axial flow. Confinement by rigid boundaries is known to affect flag flutter thresholds and fluttering dynamics significantly, and this work considers the effects of a more general confinement involving a deformable free surface. To this end, a local linear stability is proposed for a flag in axial uniform flow and parallel to a free surface, using one-dimensional beam and potential flow models to revisit this classical fluid-structure interaction problem. The physical behaviour of the confining free surface is characterized by the Froude number, corresponding to the ratio of the incoming flow velocity to that of the gravity waves. After presenting the simplified limit of infinite span (i.e. two-dimensional problem), the results are generalized to include finite-span and lateral confinement effects. In both cases, three unstable regimes are identified for varying Froude number. Rigidly-confined flutter is observed for low Froude number, i.e. when the free surface behaves as a rigid wall, and is equivalent to the classical problem of the confined flag. When the flow and wave velocities are comparable, a new instability is observed before the onset of flutter (i.e. at lower reduced flow speed) and results from the resonance of a structural bending wave and one of the fundamental modes of surface gravity waves. Finally, for large Froude number (low effect of gravity), flutter is observed with significant but passive deformation of the free surface in response of the flag's displacement.

description: The study analyzed the impact of adoption of improved groundnut varieties on farm inputs demand and productivity using instrumental variables approach. The data was collected from a simple random sample of 161 groundnut farmers in Eastern Uganda. Econometric results show significant increase in expenditure on improved seed and labor among adopters relative to the non-adopters. Adoption of improved varieties significantly increased groundnuts yield, by about 1688kg per hectare. Thus, more effort is needed to increase farmers’ access to improved varieties. The Government and partners should facilitate the development of local seed multiplication systems to reduce the cost of improved seed..

description: Recently, the higher order averaging method for studying periodic solutions of both Lipschitz differential equations and discontinuous piecewise smooth differential equations was developed in terms of Brouwer degree theory. Between the Lipschitz and the discontinuous piecewise smooth differential equations, there is a huge class of differential equations lacking in a higher order analysis on the existence of periodic solutions, namely the class of continuous non-Lipschitz differential equations. In this paper, based on the coincidence degree theory for nonlinear operator equations, we perform a higher order analysis of continuous (non-Lipschitz) perturbed differential equations and derive sufficient conditions for the existence of periodic solutions for such systems. We apply our results to study continuous (non-Lipschitz) higher order perturbations of a harmonic oscillator.

description: An ensemble approach for force networks in static granular packings is developed. The framework is based on the separation of packing and force scales, together with an a-priori flat measure in the force phase space under the constraints that the contact forces are repulsive and balance on every particle. In this paper we will give a general formulation of this force network ensemble, and derive the general expression for the force distribution $P(f)$. For small regular packings these probability densities are obtained in closed form, while for larger packings we present a systematic numerical analysis. Since technically the problem can be written as a non-invertible matrix problem (where the matrix is determined by the contact geometry), we study what happens if we perturb the packing matrix or replace it by a random matrix. The resulting $P(f)$'s differ significantly from those of normal packings, which touches upon the deep question of how network statistics is related to the underlying network structure. Overall, the ensemble formulation opens up a new perspective on force networks that is analytically accessible, and which may find applications beyond granular matter.

description: We used survey data collected from cotton producers in eleven U.S. states to address the issues of correlated events and individual heterogeneity in multiple precision technologies adoption. Results from a conditional frailty model indicated that younger, better educated cotton producer adopted precision technology quickly once those technologies were available. Further, farm size and farm income have positive influence on a chance of technology adoption by the cotton farmers. Moreover, the conditional frailty model addresses for both heterogeneity and event dependence allowing different baseline hazards for each group of precision technology adopters.

description: Far-infrared Transition Edge Sensors (TESs) are being developed for the SAFARI grating spectrometer on the cooled-aperture space telescope SPICA. In support of this work, we have devised a cryogenic (90 mK) test facility for carrying out precision optical measurements on ultra-low-noise TESs. Although our facility is suitable for the whole of the SAFARI wavelength range, 34-230 $μ$m, we focus on a representative set of measurements at 60-110 $μ$m using a device having a Noise Equivalent Power (NEP) of 0.32 $\mathrm{aW/\sqrt{Hz}}$. The system is able to perform a range of measurements: (i) Dark electrical characterisation. (ii) Optical efficiency with respect to a partially coherent beam having a modal composition identical to that of an ideal imaging telescope. (iii) Optical saturation and dynamic range. (iv) Fast optical transient response to a modulated thermal source. (v) Optical transient response in the presence of high-level background loading. We describe dark measurements to determine the operating characteristics of a TES, and then compare predicted optical behaviour with measured optical behaviour. By comparing electrical and optical transient response, we were able to observe thermalisation in the device. We comment on the challenge of eliminating stray light.
Comparative analysis of the floristics, soil chemistry, and vegetation-soil-environment relationships at an ultramafic (serpentine) site in southern British Columbia, Canada
Creators: name: Lewis, Gary John
Publisher: name: University of British Columbia

description: Ultramafic soils present an adverse chemical and physical edaphic environment for plant growth characterized by high metal toxicity, low fertility, and frequently unstable and dry conditions. The associated vegetation tends to be distinct from surrounding areas in species composition and structure and often supports high levels of endemism, speciation, and ecotypic differentiation. The general goals of this thesis were to characterize the influence of ultramafic bedrock on the overlying vegetation in southern British Columbia through a detailed comparison of adjacent ultramafic and non-ultramafic soils and to expand the knowledge of the floristics and ecology of ultramafic sites in the province. Grasshopper Mountain, part of the Tulameen ultramafic complex of southern British Columbia, was selected as the study site since the configuration of adjacent ultramafic and non-ultramafic substrata minimized potential confounding factors. Univariate and multivariate analyses of the soil data revealed three different soil types, each with distinct soil chemistry. The most important factors in distinguishing between soil types were related to soil fertility and metal toxicity. Clear floristic and ecological differences were documented between ultramafic and adjacent non-ultramafic soils. Ultramafic soils supported 28 percent of the local species richness and hosted more rare taxa than non-ultramafic soils. Many species showed patterns of local restriction to or exclusion from ultramafic soil habitats. Patterns of plant family richness and abundance and plant ecological group abundance were distinctly different on ultramafic versus non-ultramafic substrata. Multivariate analyses at the landscape, plant community, and species scales, revealed a widespread influence of ultramafic soils on the vegetation. The landscape scale analysis revealed that the main variation in the vegetation data was related to variation in the measured soil and environmental factors. In the community level analysis four main plant communities were recognized by cluster analysis: 1) ultramafic non-forest, 2) ultramafic forest, 3) non-ultramafic upper elevation forest, and 4) non-ultramafic lower elevation forest. Each of these communities was characterized by multiple significant differences based on ANOVA results of mean soil and environmental factors. Two main soil chemistry gradients were defined using non-metric multidimensional scaling: a primary "toxicity-fertility" gradient and a secondary "alkalinity" gradient which clearly separated the four plant communities within ordination space. The species level analysis revealed clear patterns of species response to ultramafic soils and related factors.

description: Recent developments in the physics of low density trapped gases make it worthwhile to verify old, well known results that, while plausible, were based on perturbation theory and assumptions about pseudopotentials. We use and extend recently developed techniques to give a rigorous derivation of the asymptotic formula for the ground state energy of a dilute gas of $N$ fermions interacting with a short-range, positive potential of scattering length $a$. For spin 1/2 fermions, this is $E \sim E^0 + (\hbar^2/2m) 2 πN ρa$, where $E^0$ is the energy of the non-interacting system and $ρ$ is the density. A similar formula holds in 2D, with $ρa$ replaced by $ρ/|\ln(ρa^2)|$. Obviously this 2D energy is not the expectation value of a density-independent pseudopotential.

description: This study estimated the impact of nutrition information provided by popular media on consumers’ purchases in U.S. grocery stores, taking omega-3 fortified eggs as an example. The media index was constructed from multiple information sources by utilizing computer-coded content analysis. Their probability of purchasing omega-3 eggs between 1998 and 2007 based on household-level scanner data was analyzed by logistic regression models to incorporate elements of information effects. The results showed the significant positive impact of nutritional information from the popular media on consumers’ food choices, thus publishing in popular media can be an effective communication approach to promote consumers’ health.

description: We present observations of 25 transitions of 17 isotopologues of 9 molecules toward B335. With a goal of constraining chemical models of collapsing clouds, we compare our observations, along with data from the literature, to models of chemical abundances. The observed lines are simulated with a Monte Carlo code, which uses various physical models of density and velocity as a function of radius. The dust temperature as a function of radius is calculated self-consistently by a radiative transfer code. The gas temperature is then calculated at each radius, including gas-dust collisions, cosmic rays, photoelectric heating, and molecular cooling. The results provide the input to the Monte Carlo code. We consider both {\it ad hoc} step function models for chemical abundances and abundances taken from a self-consistent modeling of the evolution of a star-forming core. The step function models can match the observed lines reasonably well, but they require very unlikely combinations of radial variations in chemical abundances. Among the self-consistent chemical models, the observed lines are matched best by models with somewhat enhanced cosmic-ray ionization rates and sulfur abundances. We discuss briefly the steps needed to close the loop on the modeling of dust and gas, including off-center spectra of molecular lines.

description: A modified Central Bureau of Statistics (CBS) differential model was used to evaluate the impact of Japan’s 2004 HPAI-outbreaks and US 2003 BSE-outbreaks on Japan’s meat import demand system, including cooked poultry, uncooked poultry, beef, pork, and other meats. Analysis indicated that the HPAI-BSE events led to statistically significant shifts in Japan’s import demand for all meats, except for uncooked poultry. In the Post-BSE-HPAI era, imports of meat shifted toward rising demand for cooked poultry and pork meats and declining demand for uncooked poultry, beef, and other meats. The differentiation of poultry into cooked and uncooked meat products and the inclusion of both in modeling Japan’s meat demand system revealed two opposing trends never before reported; a decreasing demand for uncooked meat and an increasing demand for safer cooked poultry meat.
