description: The highly luminous (> 10^37 erg s^-1) supersoft X-ray sources (SSS) are believed to be Eddington limited accreting white dwarfs undergoing surface hydrogen burning. The current paradigm for SSS involves thermally unstable mass transfer from a 1-2 solar mass companion. However this model has never been directly confirmed and yet is crucial for the evolution of cataclysmic variables in general, and for the establishment of SSS as progenitors of type Ia supernovae in particular. The key SSS is RX J0513.9-6951 which has recurrent X-ray outbursts every 100-200 d (lasting for ~40 d) during which the optical declines by 1 mag. We present the first XMM-Newton observations of RX J0513.9-6951 through one of its optical low states. Our results show that as the optical low state progresses the temperature and the X-ray luminosity decrease, behaviour that is anti-correlated with the optical and UV emission. We find that as the optical (and UV) intensity recover the radius implied by the spectral fits increases. The high resolution spectra show evidence of deep absorption features which vary during the optical low state. Our results are consistent with the predictions of the white dwarf photospheric contraction model proposed by Southwell et al. 1996.

description: Research background: Crop genetic resource conservation and management requires farmers’ financial and labour contribution. Guizotia abyssinica (locally named as ‘Noug’) is among the oil crops originated from Ethiopia, but currently neglected and poorly managed resource. Purpose of the article: The purpose of this research to understand farmers’ behaviour for conservation program and identify better policy, by examining factors affecting households’ willingness to pay (WTP) for conservation Guizotia abyssinica, and by estimating the aggregate welfare contribution of household for the proposed conservation program in West Shewa, Ethiopia. Methods: A contingent valuation survey, double bound with an open-ended follow-up question was directed on 160 selected rural households using multi-stage sampling method. Probit model is employed to achieve the purpose of this study. Findings & Value added: The probit model result showed that factors, such as the amount of credit received, perception of conservation problem, education, frequency of extension contact, proportion of land allocated to Guizotia abyssinica, income from Guizotia abyssinica and income from farm activity have a positive and statistically significant effect on households’ WTP. On the other hand, total livestock holding, age of households, and initial bid have a negative and significant effect WTP. The aggregate welfare contribution household was estimated to be 1,718,059 man-days and 23,260,839 Ethiopian Birr per year. Improving farmer’s extension contact, training farmers, education and solving financial constraints can increase the farmers Guizotia abyssinica conservation in the study area.

description: Taking the Jiuquan City, Guansu Provice, China as an example, according to the 1997-2007 Gansu Statistical Yearbook, Jiuquan Statistical Yearbook, the Second National Land Investigation in Jiuquan City and other relevant statistical data, models of minimum cultivated area per capita and pressure index of cultivated land are used based on food security. Cultivated land area, population, grain output, sowing area and other factors in years 1997-2007, which affect the cultivated land pressure in arid and semi-arid areas, are analyzed and estimated, as well as the temporal variations of minimum cultivated area per capita and pressure index of cultivated land. Pressure index of cultivated land in Jiuquan City is calculated and the pressure situation of cultivated land at present is analyzed. Based on the construction of demand function of cultivated land, demand of cultivated land, that is, the protected area of basic farmland and cultivated land, is finally obtained so as to achieve the goal of food security in Jiuquan City at the stage of comprehensive construction of a well-off society in the year 2020. Considering the food security of China, we use PSR Model and find out that it is necessary to strengthen government’s macro-control functions, to protect the fragile ecological environment, to improve the land intensive and economical use during the process of urbanization, and to reduce the pressure of cultivated land in arid and semi-arid region, and to provide theoretical basis for the policy making of cultivated land protection in this region.
Is electromagnetic gauge invariance spontaneously violated in superconductors?

Publisher: name: arXiv
Year: 2005
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: We aim to give a pedagogical introduction to those elementary aspects of superconductivity which are not treated in the classic textbooks. In particular, we emphasize that global U(1) phase rotation symmetry, and not gauge symmetry, is spontaneously violated, and show that the BCS wave function is, contrary to claims in the literature, fully gauge invariant. We discuss the nature of the order parameter, the physical origin of the many degenerate states, and the relation between formulations of superconductivity with fixed particle numbers vs. well defined phases. We motivate and to some extend derive the effective field theory at low temperatures, explore symmetries and conservation laws, and justify the classical nature of the theory. Most importantly, we show that the entire phenomenology of superconductivity essentially follows from the single assumption of a charged order parameter field. This phenomenology includes Anderson's characteristic equations of superfluidity, electric and magnetic screening, the Bernoulli Hall effect, the balance of the Lorentz force, as well as the quantum effects, in which Planck's constant manifests itself through the compactness of the U(1) phase field. The latter effects include flux quantization, phase slippage, and the Josephson effect.

description: Die vorliegende Masterarbeit untersucht die Rolle und Bedeutung von Strafen im sozialpädagogischen
Heimkontext und beleuchtet dabei die zugrunde liegenden organisationalen, professionellen
und individuellen Bedingungen. Ausgangspunkt der Arbeit ist die Beobachtung, dass Strafen
trotz ihrer Alltäglichkeit in der Praxis der Sozialen Arbeit nur unzureichend reflektiert und wissenschaftlich
untersucht werden. Die Arbeit ist geleitet durch die Fragestellung, inwiefern Sozialpädagoginnen
und Sozialpädagogen in Teambesprechungen über Strafen als Reaktionsmöglichkeit
auf abweichendes Verhalten von Jugendlichen sprechen. Da sich Strafen im sozialpädagogischen
Kontext nur bedingt als isolierter Gegenstand untersuchen lassen, werden die wesentlichen Wirkungszusammenhänge
mitverfolgt. Das ethnographische Forschungsdesign mittels teilnehmender
Beobachtung während sozialpädagogischen Teambesprechungen eines Jugendheims zeigte
sich erkenntnisreich. Die Arbeit ermöglicht der Leserschaft Zugang zu Funktion, Ordnung und Inhalte
sozialpädagogischer Teambesprechungen. Die daraus gewonnenen zentralen Erkenntnisse
hinsichtlich strafender Praktiken wurzeln in den Organisationsstrukturen als unterbelichteten
Wirkungszusammenhang. Daran anschliessend ermöglicht die theoretische und empirische Auseinandersetzung
handlungspraktische Schlussfolgerungen und Empfehlungen für die Soziale Arbeit.

description: We investigate the phenomenon of multilayer formation via layer-by-layer deposition of alternating charge polyelectrolytes. Using mean-field theory, we find that a strong short-range attraction between the two types of polymer chains is essential for the formation of multilayers. The dependence of the required short-range attraction on the polymer charge fraction and salt concentration is calculated. For weak short-range attraction between any two adjacent layers, the adsorbed amount (per added layer) decays as the distance from the surface increases, until the chains stop adsorbing altogether. For strong short-range attraction, the adsorbed amount per layer increases after an initial decrease, and finally it stabilizes in the form of a polyelectrolyte multilayer that can be repeated many times.

description: Based on the introduction of research theories about rural labor force transfer at home and abroad, taking Liaocheng City as the representative of medium and small cities, transfer situation of rural labor force in Liaocheng City is discussed from several aspects, including the transfer of total labor force, structure of labor force, flow of regional labor force, industry selection of labor force, and income of labor force. Combining with the situation of labor force transfer in Liaocheng City, social benefits, including both negative and positive benefits, of labor force transfer are analyzed. From the aspect of positive benefit, foreign labor is one of premier builders for in-flow area (city), fills in the structural lack of labor force, and has made huge contributions to urban construction. Meanwhile, for out-flow area (village), transfer of surplus labor force can reduce the employment pressure in rural areas, increase the income of peasant households, and promote the development of rural economy. From the aspect of negative benefit, a large number of labor forces pouring into cities will bring pressure on the transportation and infrastructure, increase the instability factor of city, and cause difficulties in the management of city. At the same time, a large number of young labor forces work in cities, leaving only the old and sick in rural areas. This might become a hidden danger to the development of agriculture. Push-Pull Theory is used to analyze the socio-economic factors affecting labor force transfer. Suggestions are put forward to reform the household registration system, to improve the cultural quality of rural labor force, to develop rural secondary and tertiary industries, to promote the rapid and harmonious development of economic society in underdeveloped regions, and to provide scientific reference for the sustainable development of regional economy and the construction of new socialist countryside in Liaocheng City.

description: Sources of entangled electromagnetic radiation are a cornerstone in quantum information processing and offer unique opportunities for the study of quantum many-body physics in a controlled experimental setting. While multi-mode entangled states of radiation have been generated in various platforms, all previous experiments are either probabilistic or restricted to generate specific types of states with a moderate entanglement length. Here, we demonstrate the fully deterministic generation of purely photonic entangled states such as the cluster, GHZ, and W state by sequentially emitting microwave photons from a controlled auxiliary system into a waveguide. We tomographically reconstruct the entire quantum many-body state for up to $N=4$ photonic modes and infer the quantum state for even larger $N$ from process tomography. We estimate that localizable entanglement persists over a distance of approximately ten photonic qubits, outperforming any previous deterministic scheme.

description: Farmland and capital are an important and rapidly expanding component of the agricultural economy, and empirical evidence suggests that these assets are quasi-fixed in that adjustment costs are incurred when holdings are altered. Increased interest in the rate of return for investing in farmland suggests that an important consideration is the effect of adjustment costs on this return. A novel theoretical model is developed that ties together contributions from the farmland pricing and adjustment cost literatures, and the first order conditions for a utility maximizing decision maker are rearranged into intertemporal arbitrage equations that are similar in spirit to traditional finance models. The common assumptions that land and capital are quasi-fixed assets, and that production is characterized by constant returns to scale are tested and the evidence supports these assumptions. An empirical application of the arbitrage equations provides evidence that risk aversion and adjustment costs are jointly significant components of agricultural production, and that adjustment costs generate significant changes in the rate of return to farmland. The results have important policy implications as sluggish supply response due to quasi-fixity can lead to dramatically inflated commodity prices, and an accurate measure of the farmland return can help determine how far the extensive margin will expand or contract in response to a variety of policy scenarios, such as the subsidization of corn for ethanol, an increase in the variety of subsidized crop insurance products, or the introduction of new revenue support programs such as ACRE.

description: One of the most fundamental and traditional risk management tools available to agricultural producers is a savings account. Cash reserves in savings provide a safety net for producers, allowing financial obligations and living expenses to be met when unexpected shortfalls in income occur. Crop insurance, another risk management tool, likely reduces the cash reserves required to be held in savings as it aids in mitigating risks ranging from total disasters to uncertainties in market conditions. This study utilizes a stochastic farm level simulation model in a representative farm framework to evaluate the impacts of alternative crop insurance scenarios on levels of savings necessary to maintain target ending cash reserve numbers for producers in major production areas of the Southern United States.

description: Research background: In the current competitive agricultural market, where substantial capital investment is required to pursue growth related competitive strategies, agricultural cooperatives’ performance mainly relies on members’ willingness to contribute equity capital. Members are the single and most important source of investment capital. Purpose of the article: This study investigated factors influencing members’ willingness to contribute equity capital to their agricultural cooperatives in Ethiopia with the intention of providing empirical evidences to decision makers with regard to specific measures to be taken to enhance members’ willingness to contribute equity capital, and thereby improve agricultural cooperatives’ performance. Methods: Multi-stage random sampling technique was employed to select the study districts, farmer associations, agricultural cooperatives and respondent households. Semi-structured questionnaire was employed to collect cross-sectional data from randomly selected 214 households. The data were analysed using binary logistic regression model. Findings & value added: We found that education level; past role as a committee member; trust on other members’ commitment and directors’ leadership – influence positively and significantly members’ willingness to contribute equity capital. While age and perception on the cooperatives’ weaknesses affect negatively and significantly members’ willingness. The important policy recommendations are developing and fostering trust among members and between members and directors; re-orienting service provisions in line with the needs and interests of their members; assessing agricultural cooperatives’ performance depending on the values that their members expect to obtain from membership. This study investigated the influence of trust on members’ willingness to contribute equity capital, and hence will add value to better understanding of the role of trust in enhancing members’ commitment in cooperative organizations. Lastly, this cross-sectional survey study subjected to limitations associated with this type of study. Hence the generalizability of its results to other areas of agricultural cooperatives needs further investigation.

description: The integrated Sachs-Wolfe (ISW) effect in a Lambda dominated universe can be an important factor in the evolution of cosmic microwave background fluctuations. With the inclusion of cosmological constant we present the complete analytic solution of the covariant linear perturbations of the Einstein equations in the Newtonian gauge, in the case of a spatially flat (K=0), Friedman-Robertson-Walker (FRW) universe, filled with pressureless ideal fluid. We use the analytic time dependence of the perturbation potentials to derive the anisotropy power spectrum of the late ISW effect. We choose the scale invariant Harrison-Zeldovich spectrum for obtaining the C_l momenta and show the agreement of our results with earlier, numeric calculations.

description: A detailed analysis of damping and noise due to a {\it sd}-interaction in a thin ferromagnetic film sandwiched between two large normal metal layers is carried out. The magnetization is shown to obey in general a non-local equation of motion which differs from the the Gilbert equation and is extended to the non-adiabatic regime. To lowest order in the exchange interaction and in the limit where the Gilbert equation applies, we show that the damping term is enhanced due to interfacial effects but it also shows oscillations as a function of the film thickness. The noise calculation is however carried out to all orders in the exchange coupling constant. The ellipticity of the precession of the magnetization is taken into account. The damping is shown to have a Gilbert form only in the adiabatic limit while the relaxation time becomes strongly dependent on the geometry of the thin film. It is also shown that the induced noise characteristic of sd-exchange is inherently colored in character and depends on the symmetry of the Hamiltonian of the magnetization in the film. We show that the sd-noise can be represented in terms of an external stochastic field which is white only in the adiabatic regime. The temperature is also renormalized by the spin accumulation in the system. For large intra-atomic exchange interactions, the Gilbert-Brown equation is no longer valid.

description: We describe an approach to the quantization of (2+1)--dimensional gravity with topology R x T^2 and negative cosmological constant, which uses two quantum holonomy matrices satisfying a q--commutation relation. Solutions of diagonal and upper--triangular form are constructed, which in the latter case exhibit additional, non--trivial internal relations for each holonomy matrix. This leads to the notion of quantum matrix pairs. These are pairs of matrices with non-commuting entries, which have the same pattern of internal relations, q-commute with each other under matrix multiplication, and are such that products of powers of the matrices obey the same pattern of internal relations as the original pair. This has implications for the classical moduli space, described by ordered pairs of commuting SL(2,R) matrices modulo simultaneous conjugation by SL(2,R) matrices.

description: Type-I proton superconducting cores of neutron stars break up in a magnetic field into alternating domains of superconducting and normal fluids. We examine two channels of superfluid-normal fluid friction where (i) rotational vortices are decoupled from the non-superconducting domains and the interaction is due to the strong force between protons and neutrons; (ii) the non-superconducting domains are dynamically coupled to the vortices and the vortex motion generates transverse electric fields within them, causing electronic current flow and Ohmic dissipation. The obtained dissipation coefficients are consistent with the Eulerian precession.

description: Faced with a dynamic change in U.S. trout imports, this study tried to identify how trout imports affect the domestic trout industry in the United States. In doing so, this study analyzed the quantity effect and exchange rate effect on domestic trout price using a modified LDI-AIDS model. According to the results of this study, we found five important facts related to trout imports during this sample period of time. First, a low farm price of domestic trout might be due to reasons other than trout imports because empirical results show that the net effects of imported trout products are complementary rather than substitutionary in effect. Second, domestic trout price decreases with an increase in total trout supply into domestic market. Third, imported frozen products are gross-substitutes for domestic product, while imported fresh products are gross-complements for domestic product. Fourth, for domestic trout, the intensity of substitutable interaction of imported products is as follows: frozen fillets > frozen whole trout > fresh whole trout > rainbow trout. Finally, depreciation of the U.S. Dollar relative to the Chilean Peso reduces the negative impact of Chilean imported trout on domestic trout price.

Phase transitions in nanosystems caused by interface motion: The Ising bi-pyramid with competing surface fields

description: The phase behavior of a large but finite Ising ferromagnet in the presence of competing surface magnetic fields +/- H_s is studied by Monte Carlo simulations and by phenomenological theory. Specifically, the geometry of a double pyramid of height 2L is considered, such that the surface field is positive on the four upper triangular surfaces of the bi-pyramid and negative on the lower ones. It is shown that the total spontaneous magnetization vanishes (for L -> infinity) at the temperature T_f(H), related to the "filling transition" of a semi-infinite pyramid, which can be well below the critical temperature of the bulk. The discontinuous vanishing of the magnetization is accompanied by a susceptibility that diverges with a Curie-Weiss power law, when the transition is approached from either side. A Landau theory with size-dependent critical amplitudes is proposed to explain these observations, and confirmed by finite size scaling analysis of the simulation results. The extension of these results to other nanosystems (gas-liquid systems, binary mixtures, etc.) is briefly discussed.

description: The effect exchange rates have on local prices may induce a change in relative prices and import demand. This study shows that substitutability, endogeneity of foreign price, elasticity of substitution, and degree of returns to scale influence the impacts exchange rates have on relative prices and import demand. In an empirical examination of the Korean beef market, this study found a decrease in relative prices and an increase in import demand when the U.S. dollar depreciates, and an increase in relative prices and a decrease in import demand when the U.S. dollar appreciates. However, the effect on relative prices is greater than the effect on import demand, implying that the foreign price elasticity of import demand is less than one.
description: The purpose of this study is to determine the impact the exchange rate has on local prices and import demand.

description: Playa lakes are very important to the Texas High Plains. They provide habitat for a wide variety of wildlife, and are the Ogallala Aquifer’s primary recharge source. Plowing and sedimentation have caused substantial damage to the overall health of many playas. A need exists to protect this resource for future generations. Several government programs are available to assist landowners with playa preservation including CP23A, the Wetlands Reserve Program, and the Wildlife Habitat Incentive Program. This study evaluates each conservation program and weighs the economic benefits and costs of program implementation.

description: Spontaneous chiral symmetry breaking, mesons and baryons are illustrated in the language of the Dirac theory. Various forces acting between quarks inside baryons are discussed. I explain why the naive quark models typically overestimate pentaquark masses by some 500 MeV and why in the fully relativistic approach to baryons pentaquarks turn out to be light. I discuss briefly why it can be easier to produce pentaquarks at low than at high energies.

description: We study the cross-correlation between 212 MgII quasar absorption systems and \~20,000 Luminous Red Galaxies (LRGs) selected from the Sloan Digital Sky Survey Data Release 1 in the redshift range 0.4=1.0 Angstrom and identifications confirmed by the FeII 2600 or MgI 2852 lines. Over comoving scales 0.05--13 h^-1 Mpc, the MgII--LRG cross-correlation has an amplitude 0.69+/-0.09 times that of the LRG--LRG auto-correlation. Since LRGs have halo-masses greater than 3.5 x 10^12 solar masses for M_R=0.3 Angstrom are associated with ~0.7 L^*_B galaxies.

description: The COVID-19 pandemic has highlighted the importance of in-silico epidemiological modelling in predicting the dynamics of infectious diseases to inform health policy and decision makers about suitable prevention and containment strategies. Work in this setting involves solving challenging inference and control problems in individual-based models of ever increasing complexity. Here we discuss recent breakthroughs in machine learning, specifically in simulation-based inference, and explore its potential as a novel venue for model calibration to support the design and evaluation of public health interventions. To further stimulate research, we are developing software interfaces that turn two cornerstone COVID-19 and malaria epidemiology models COVID-sim, (https://github.com/mrc-ide/covid-sim/) and OpenMalaria (https://github.com/SwissTPH/openmalaria) into probabilistic programs, enabling efficient interpretable Bayesian inference within those simulators.

description: Nonlinear topological photonics, which explores topics common to the fields of topological phases and nonlinear optics, is expected to open up a new paradigm in topological photonics. Here, we demonstrate second-harmonic generation (SHG) via nonlinear interaction of double topological valley-Hall kink modes in all-dielectric photonic crystals (PhCs). We first show that two topological frequency bandgaps can be created around a pair of frequencies, $ω_0$ and $2ω_0$, by gapping out the corresponding Dirac points in two-dimensional honeycomb PhCs. Valley-Hall kink modes along a kink-type domain wall interface between two PhCs placed together in a mirror-symmetric manner are generated within the two frequency bandgaps. Importantly, through full-wave simulations and mode dispersion analysis, we demonstrate that tunable, bi-directional phase-matched SHG via nonlinear interaction of the valley-Hall kink modes inside the two bandgaps can be achieved. In particular, by using Stokes parameters associated to the magnetic part of the valley-Hall kink modes, we introduce a new concept, SHG directional dichroism, which is employed to characterize optical probes for sensing chiral molecules. Our work opens up new avenues towards topologically protected nonlinear frequency mixing and active photonic devices implemented in all-dielectric material platforms.
