description: Ultracold mixtures of different atomic species have great promise for realizing novel many-body phenomena. In a binary mixture of femions with a large mass difference and repulsive interspecies interactions, a disordered Mott insulator phase can occur. This phase displays an incompressible total density, although the relative density remain compressible. We use strong-coupling and Monte Carlo calculations to show that this phase exists for a broad parameter region for ultracold gases confined in a harmonic trap on a three-dimensional optical lattice, for experimentally accessible values of the trap parameters.

description: With a sample of farms in the European Union (EU) and Farm Accountancy Data Network (FADN) data completed by additional data, we illustrate how the effect of farm subsidies on technical efficiency changes when environmental (good or bad) outputs are incorporated in the calculation of technical efficiency. Results indicate that the effect of the Common Agricultural Policy (CAP) operational subsidies on farm technical efficiency changes when environmental outputs (in this study: greenhouse gas emissions, nitrogen balance and ecological focus areas) are taken into account in the efficiency calculation: some effects change significance, and more importantly, some effects change sign.

description: Motivated by recent research on product differentiation, we conduct laboratory experiments to study how (aggregate) demand uncertainty influences location choices and price competition in the original Hotelling (1929)’s model. We provide new predictions on the effect of risk attitudes on both decisions under demand uncertainty and confront them with the data. Our experimental results support the predictions that demand uncertainty acts as a differentiation force for risk-neutral and risk-lover subjects. By contrast, we do not verify that demand uncertainty leads risk-averse subjects to agglomerate. This is explained primarily by learning effects and heterogeneous behaviors within this risk profile. Finally, we observe various price-setting behaviors, ranging from an attempt to collude to a price war, depending on the level of differentiation.

description: If a sequence $(a_n)$ of non-negative real numbers has ``best possible'' distribution in arithmetic progressions, Bombieri showed that one can deduce an asymptotic formula for the sum $\sum_{n\le x} a_n Λ_k(n)$ for $k\ge 2$. By constructing appropriate sequences, we show that any weakening of the well-distribution property is not sufficient to deduce the same conclusion.

description: In this paper, we are interested to focus on the critical periods in the economy which are characterized by large fluctuations in macroeconomic indicators. To capture unusual and large fluctuations of inflation and unemployment, we concentrate on the non-Gaussianity of their distributions. To this aim, by using the coupled multifractal approach, we analyze US data for a period of 70 years from 1948 until 2018 and measure the non-Gausianity of the distributions. Then, we investigate how the non-Gaussianity of the variables affects the coupling structure of them. By applying the multifractal method, one can see that the non-Gaussianity depends on the scales. While the non-Gaussianity of unemployment is noticeable only for periods smaller than 1 year and for longer periods tends to Gaussian behavior, the non-Gaussianities of inflation persist for all time scales. Also, it is observed that the coupling structure of these variables tends to a Gaussian behavior after $2$ years.

description: Microbial pathogens in food cause between 6.5 million and 33 million cases of human illness and up to 9, 000 deaths each year in the United States. Over 40 different foodborne pathogens are believed to cause human illness. The annual cost of human illness caused by seven foodborne pathogens for which we have estimates ranges between $5.6 billion and $9.4 billion. Meat and poultry are the primary sources. Microorganisms are commonly found in soil, water, plants, and animals. Most do not cause human illness. In fact, we rely on some microorganisms in the making of bread, alcohol, cheese, vitamins, and antibiotics. Some, however, do cause human illness. Pathogens-microorganisms that cause disease-include viruses, bacteria, parasites, and fungi. The bacterium Staphylococcus aureus lives harmlessly on human skin and in nasal cavities of less than half the people in the United States, but in food it can produce toxins that cause human illness. Another bacterium Escherichia coli O157:H7 usually lives harmlessly in the intestinal tracts of some cattle, but in people it can cause serious illness, including bloody diarrhea and kidney failure, as well as premature death. People can acquire the bacteria by eating mishandled or insufficiently cooked meat from infected animals. Half of all foodborne illnesses have no identified cause. Yet those foodborne illnesses that are confirmed and reported to the Centers for Disease Control and Prevention (CDC), over 90 percent are attributed to bacteria. Increasing Government scrutiny over food safety is improving efforts to restrict microbial pathogens in the food supply-as well as to improve data on the numbers of cases and costs associated with these pathogens. This article is the first in a new Economic Research Service series that will track the estimated costs and incidence of seven foodborne diseases over time (see box on key foodborne pathogens). These diseases were chosen for this series because they are commonly found in meat and poultry. Public-health officials can compare the cost-of-illness (COI) estimates to identify the most expensive foodborne pathogens and illnesses COI estimates can also be compared with the costs of pathogen-control programs to determine what level and direction of intervention may be needed.

description: Topological phases of matter are primarily studied in quantum many-body systems with short-range interactions. Whether various topological phases can survive in the presence of long-range interactions, however, is largely unknown. Here we show that a paradigmatic example of a symmetry-protected topological phase, the Haldane phase of an antiferromagnetic spin-1 chain, surprisingly remains intact in the presence of arbitrarily slowly decaying power-law interactions. The influence of long-range interactions on the topological order is largely quantitative, and we expect similar results for more general systems. Our conclusions are based on largescale matrix-product-state simulations and two complementary effective-field-theory calculations. The striking agreement between the numerical and analytical results rules out finite-size effects. The topological phase considered here should be experimentally observable in a recently developed trapped-ion quantum simulator.

description: The Barn Coffee Shop is currently losing money, thus threatening its economic sustainability. Recognizing that economic sustainability is interconnected with ecological and social sustainability, we believe that enhancing the ecological and social sustainability of the Barn will facilitate improvements in economic sustainability. Using past surveys, conducting our own surveys, using websites and personal interviews, we found that faculty and staff comprise the majority of the Barn’s customers, but that students are interested in the up-coming changes. These changes include removal of the grill and offering daily paninis and pastas, incorporating Tim Horton’s coffee and baking, and possibly fostering a partnership with the UBC farm. We assessed sustainability through indicators such as amount and type of waste, profits or losses, and customer satisfaction surveys. Through our strong anthropocentric viewpoint, we recommend improving ecological and social aspects of the Barn to improve the economical sustainability. Primary recommendations include: elimination of Styrofoam, conversion to paper take-out containers, improved advertising for special features, establishment of a partnership with the UBC farm, and education of staff on sustainability issues. Suggestions for future research include measuring indicators once renovations are complete and recommendations are implemented to determine their impact on economic, ecological and social sustainability of the Barn.

description: The increasing demand for agricultural commodities for food and energy purposes has led to intensified agricultural production. This trend may manifest in agricultural compositions and landscape configurations that can have mixed and adverse impacts on the provision of ecosystem services. We rely on the EU’s plot-based data from the Integrated Administration and Control System (IACS) to identify different types of agricultural landscapes and their spatial distribution in Brandenburg, Germany, a study region strongly characterised by intensification trends. Based on a set of landscape metrics, we are able to characterise agricultural land use and identify six types of agricultural landscapes. We rely on a two-step cluster analysis for a hexagonal grid and find that agricultural land is dominated by cropland with different degrees of fragmentation. By providing a framework using landscape metrics derived from IACS data, our approach involves clustering to identify typologies that are transferable to other regions within the EU based on existing data. This framework can offer more tailored environmental and agricultural planning based on sophisticated measures that take into account local and regional characteristics.

Nonlinear effects in microwave photoconductivity of two-dimensional electron systems

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We present a model for microwave photoconductivity of two-dimensional electron systems in a magnetic field which describes the effects of strong microwave and steady-state electric fields. Using this model, we derive an analytical formula for the photoconductivity associated with photon- and multi-photon-assisted impurity scattering as a function of the frequency and power of microwave radiation. According to the developed model, the microwave conductivity is an oscillatory function of the frequency of microwave radiation and the cyclotron frequency which turns zero at the cyclotron resonance and its harmonics. It exhibits maxima and minima (with absolute negative conductivity) at the microwave frequencies somewhat different from the resonant frequencies. The calculated power dependence of the amplitude of the microwave photoconductivity oscillations exhibits pronounced sublinear behavior similar to a logarithmic function. The height of the microwave photoconductivity maxima and the depth of its minima are nonmonotonic functions of the electric field. It is pointed to the possibility of a strong widening of the maxima and minima due to a strong sensitivity of their parameters on the electric field and the presence of strong long-range electric-field fluctuations. The obtained dependences are consistent with the results of the experimental observations.

description: Higher Order Topological Insulators (HOTI) are $d$-spatial dimensional systems featuring topologically protected gap-less states at their $(d-n)$-dimensional boundaries. With the help of \textit{ab-initio} calculations and tight binding models along with symmetry considerations we show that monolayer buckled honeycomb structures of group-V elements (Sb,As), which have already been synthesized, belong in this category and have a charge fractionalization of $\frac{e}{2}$ at the corner states as well as weak topological edge states, all protected by their properties under the inversion operation which classify this system as a quadrupole topological insulator.

Within errors, the mass of the pentaquark is compatible with the experimentally measured value. The mass difference between the Theta and the pentaquark with the quantum numbers of the nucleon amounts to 70 MeV, consistent with the interpretation of the N(1440) as a pentaquark.

description: We evaluate by Monte Carlo simulation the empirical sizes of Johansen's likelihood ratio tests for the number of cointegrating vectors using his tabulated asymptotic critical values. The powers of these tests and of the Dickey-Fuller and cointegrating regression Durbin-Watson tests for cointegration are compared in an experimental design where more than one cointegrating vector is possible, and where there is a possible mismatch between the variables used in the construction of the tests and the variables entering the true cointegrating vector(s). This analysis allows for potential overspecification or underspecification of the variables included in a cointegration analysis.

description: The focus of our report is on UBC Food Services (UBCFS) and their current practices within the framework of the campus community. Although there are several issues facing UBCFS, we chose to focus on a few, partially due to time constraints and primarily because our value assumptions influenced what we deem to be important problems affecting the sustainability of the UBCFS. Thus, we concentrated our efforts towards the economical, ecological, and social concerns regarding UBCFS that we felt were important to address. We investigated UBCFS from the UBCFS’ current mission statement and five-year plan, verbal communication with the director of UBCFS and a food service supervisor at Totem Park kitchen, previous surveys, as well as a survey we developed. From this research, along with our values and beliefs, we identified problems with the UBCFS and offered recommendations. We found that our proposed solutions, with great effort and extensive integration and collaboration among several parties, could feasibly be implemented.

description: We consider composite two-Higgs doublet models based on gauge-Yukawa theories with strongly interacting fermions generating the top-bottom mass hierarchy. The model features a single "universal" Higgs-Yukawa coupling, $ g $, which is identified with the top quark $ g\equiv g_t \sim \mathcal{O}(1) $. The top-bottom mass hierarchy arises by soft breaking of a $ \mathbb{Z}_2 $ symmetry by a condensate of strongly interacting fermions. A mass splitting between vector-like masses of the confined techni-fermions controls this top-bottom mass hierarchy. This mechanism can be present in a variety of models based on vacuum misalignment. For concreteness, we demonstrate it in a composite two-Higgs scheme.

description: We present our ELODIE radial-velocity measurements of HD 74156 and 14 Her (HD 145675). These stars exhibit low-amplitude radial-velocity variations induced by the presence of low-mass companions. The radial-velocity data of HD 74156 reveal the presence of two planetary companions: a 1.86 M_Jup planet on a 51.64--d orbit and a 6.2 M_Jup planet on a long-period (5.5 yr) orbit. Both orbits are fairly eccentric (e=0.64 and 0.58). The 4.7M_Jup companion to HD 145675 has a long period (4.9 yr) and a moderately eccentric orbit (e=0.34). We detect an additional linear radial-velocity trend superimposed to the periodic signal for this star. We also compute updated orbital solutions for HD 209458 and 51 Peg (HD 217014). Finally, we present our ELODIE radial-velocity data and orbital solutions for 5 stars known to host planetary companions: Ups And (HD 9826), 55 Cnc (HD 75732), 47 UMa (HD 95128), 70Vir (HD 117176) and HD 187123. We confirm the previously published orbital solutions for Ups And, 70 Vir and HD 187123. Our data are not sufficient for fully confirming the orbital solutions for 55 Cnc and 47UMa.

title: The non-chemical control of marsh ragwort (Senecio aquatius Huds.)
Creators: name: Sargent, Eleanor Mary
Publisher: name: The Open University
Year: 2011

description: Senecio aquaticus is a problematic pest species due to its toxic nature. It can cause economic and habitat loss. Senecio aquaticus occurs on the rare and very species rich MG8 plant community. This community relies on management practices including grazing and hay cutting to persist. Where S.aquaticus is prevalent agricultural abandonment could lead to habitat loss. At present there are no adequate control methods for S.aquaticus as current ones are costly or may damage habitat. This thesis aimed to take an ecological approach to this problem to find a new control method that was both cost effective and would not damage the habitat. Four potential control methods were trialled. Farmyard manure application, Lime, Drainage gutters and Early hay cut, aiming to take advantage of S.aquaticus s poor competitive ability, by promoting the surrounding vegetation and out-competing the Senecio. Early hay cut aimed to prevent seed set. Hay cut and manure decreased the Senecio population after two years, hay cut having the biggest effect. Lime and drainage did not reduce abundance although S.aquaticus abundance was demonstrated to correlate with high water table. Pot experiments revealed that cutting time should be around the 15th June to prevent plants reflowering and before seedset. Seed bank analysis indicated a short lived seed bank. Competition experiments revealed root competition to be most influential and adult plants most sensitive. Productivity decreased with competition intensity. Early hay cut had no negative impact on the plant community, however manure decreased diversity and likeness to MG8 with an increase in grass and loss of forbes. Due to this negative impact on plant community it should not be used. This study recommends the use of early hay cut around the 15th of June for two consecutive years as a S.aquaticus control method.

description: The effect of hydrostatic pressure on the superconducting transition temperature of Na{0.35}CoO{2}.yH{2}O was investigated by ac susceptibility measurements up to 1.6 GPa. The pressure coefficient of T{c} is negative and the dependence T{c}(p) is nonlinear over the pressure range investigated. The magnitude of the average dlnT{c}/dp=-0.07 GPa^{-1} is comparable to the pressure coefficient of electron-doped high-T{c} copper oxide superconductors with a similar value of T{c}. Our results provide support to the assumption of two-dimensional superconductivity in Na{0.35}CoO{2}.yH{2}O, which is similar to the cuprate systems, and suggest that intercalation of larger molecules may lead to an enhancement of T{c}.

description: One mode of atomic force microscopy (AFM) is frequency-modulation AFM, in which the tip is driven to oscillate at its resonance frequency which changes as the tip interacts with the surface. Frequency-modulation lateral force microscopy (FM-LFM) is the variant of this technique in which the tip is oscillated along the surface. For an isolated adsorbate on a flat surface, the only signal in FM-LFM is caused by the short-range interaction with the adsorbate. Various deconvolution methods exist to convert the observed frequency shift into the more physically relevant parameters of force and energy. While these methods are often used for FM-AFM data, the high number of inflection points of FM-LFM data make standard deconvolution methods less reliable. In this article, we present a method based on Fourier decomposition of FM-LFM data and apply it to data taken of an isolated CO molecule on the Pt(111) surface. We probe the potential energy landscape past the potential energy minimum and show how over an adsorbate, the potential energy can be evaluated with a single FM-LFM image.
Precursor flares of short gamma-ray bursts from crust yielding due to tidal resonances in coalescing binaries of rotating, magnetized neutron stars

description: As evidenced by the coincident detections of GW170817 and GRB 170817A, short gamma-ray bursts are likely associated with neutron star-neutron star merger events. Although rare, some bursts display episodes of early emission, with precursor flares being observed up to $\sim 10$ seconds prior to the main burst. As the stars inspiral due to gravitational wave emission, the exertion of mutual tidal forces leads to the excitation of stellar oscillation modes, which may come into resonance with the orbital motion. Mode amplitudes increase substantially during a period of resonance as tidal energy is deposited into the star. The neutron star crust experiences shear stress due to the oscillations and, if the resonant amplitudes are large enough, may become over-strained. This over-straining can lead to fractures or quakes which release energy, thereby fueling precursor activity prior to the merger. Using some simple Maclaurin spheroid models, we investigate the influence of magnetic fields and rapid rotation on tidally-forced $f$- and $r$- modes, and connect the associated eigenfrequencies with the orbital frequencies corresponding to precursor events seen in, for example, GRB 090510.

description: The first half of the 1980s was a period of economic setbacks. Ratio numbers were used to measure financial success in the Western Transvaal. Median profitability was low, but solubility favourable. Excessive use of short-term debt capital was encountered. The median ratio between gross revenue and total costs was unfavourable; over-expenditure on fertilisers, fuel and repairs in particular, reduced profitability. Large variances were encountered in most ratios and distributions were not normal. Those whose performances were weaker in terms of profitability and liquidity incurred larger costs relative to revenue and also invested more.

description: Objectives. Racial/ethnic disparities in heterosexual transmission of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) have been hypothesized to be related to the high rate of incarceration and the shortage of men in black communities. This study tested associations of having multiple sex partners with these factors. Methods. Racial/ethnic-specific Census data on the sex ratio and the male incarceration rate were categorized into tertiles and matched with individual data from the National Health and Nutrition Examination Survey 1999–2004 by county of residence for non-Hispanic black, non-Hispanic white, and Mexican American participants. We used logistic regression analyses to examine whether these factors were associated with having multiple opposite-sex partners in the past year. Results. Sex ratios and incarceration rates varied greatly by race/ethnicity; however, we observed significant associations within each racial/ethnic group. Non-Hispanic black men in counties with a greater shortage of males (adjusted odds ratio [AOR] 􀀕 1.9; 95% confidence interval [CI] 1.1, 3.5) and a greater number of incarcerated males (AOR􀀕1.6; 95% CI 1.1, 2.3) in the non-Hispanic black population had significantly greater odds of having two or more partners. Those in two low sex-ratio categories (AOR􀀕2.4; 95% CI 1.0, 5.8 and AOR􀀕4.1; 95% CI 1.6, 10.0) and one high incarceration-rate category (AOR􀀕2.1; 95% CI 1.2, 3.6) had significantly greater odds of having five or more partners. Conclusion. Sex ratios and incarceration rates were associated with the number of opposite-sex partners in some groups. Because the risk of HIV/ STI transmission depends, in part, on the number of partners, it is important to determine the causal relationships among these associations to help better understand racial/ethnic HIV/STI disparities and improve prevention programs and interventions.

description: Additional file 1: Figure S1. Selection markers for U. gibba in vitro culture. Utricularia tissue exposed to different concentrations and selection markers, observed and photographed at 9 day in MS culture. Tissue placed in Glufosinate-ammonium PESTANAL at 6,10,15 and 20 mg/l showed bleaching and dead tissue in all treatments. Utricularia tissue subjected to Kanamycin showed no effect in viability, and green tissue was observed at 20, 40, 60 and 80 mg/l. At low Hygromycin concentrations (5, 10 and 20 mg/l), U. gibba remained green and alive, while at 30 mg/l, dead tissue was observed. Wild type Utricularia photographs as experimental controls are shown. Scale bar, 1 cm. Figure S2.

description: African Americans in the United States are disproportionately affected by HIV/AIDS. We focus in this paper on the structural and contextual sources of HIV/AIDS risk, and suggest that among the most important of these sources are drug policy and the corrections system. In particular, high rates of exposure to the corrections system (including incarceration, probation, and parole) spurred in large part by federal and state governments’ self-styled war on drugs in the United States, have disproportionately affected African Americans. We review a wide range of research literature to suggest how exposure to the corrections system may affect the HIV/AIDS related risks of drug users in general, and the disproportionate HIV risk faced by African Americans in particular. We then discuss the implications of the information reviewed for structural interventions to address African American HIV-related risk. Future research must further our understanding of the relations among drug policy, corrections, and race-based disparities in HIV/AIDS.

description: We present a spectral and timing study of the High Mass X-ray Binary transient source 4U 1700-37 using NuSTAR and ASTROSAT/LAXPC. The source is observed in two different flux states. A combined spectral analysis of NuSTAR's FPMA and FPMB shows the possible hint of a cyclotron line feature at $\sim$16 keV. The line feature is consistently present in different continuum models with at least 3$σ$ confidence level. We do not detect the presence of a previously reported ~39 keV cyclotron line in the combined spectra. A $\sim$16 keV cyclotron feature would suggest that the compact object is a neutron star with a magnetic field strength $\sim2.1\times$10$^{12}$ Gauss in the emission region. We also find the presence of a rare Ni $Kα$ emission line around 7.6 keV in the NuSTAR spectrum. We searched the NuSTAR and ASTROSAT data for coherent or quasi-periodic oscillation signals but found no evidence in the frequency range 0.1 mHz to 10$^3$ Hz.

title: Young mothers, Education and Social Exclusion
Creators: name: Rudoe, Naomi Rachel

description: This thesis examines the education and social inclusion and exclusion of young mothers, focusing on the experiences of sixteen pregnant young women and mothers attending a course of antenatal education during 2007. I use a critical feminist approach to examine the meanings of education in this setting alongside the young women's mothering identities. The thesis interrogates the effects of New Labour's Teenage Pregnancy Strategy in relation to the young women in my study. I analyse how the concept of 'social exclusion' has cast the 'teenage mother' as responsible for reproducing a cycle of disadvantage, obscuring the socially including aspects of young motherhood. I argue that policy constructions of teenage motherhood are contradicted by the lived experience of the young mothers in my study. In defiance of discourses of the teenage mother as unfit mother, the young women construct themselves in many cases as ready for motherhood and as resilient adults who choose to 'take responsibility' for their actions, re-engage with education and want to 'do the best' for their children. I challenge the idea that 'interventions' such as this antenatal educational setting are part of a policy framework that seeks to teach 'middle-class' parenting methods to working-class young women. Rather, the professionals working in the setting transform policy discourses to support and defend the young women from stigma. I contrast the young women's positive experiences in the setting with their negative school experiences, and show how the process of educational disaffection often happens prior to pregnancy, and how pregnancy precipitates increased motivation. The young women use pregnancy as a way to transition from a 'bad girl' to a 'good mother' identity, and as an opportunity to re-evaluate family relationships and friendships. I conclude by making policy recommendations with regard to the education of pregnant young women and mothers.
