description: We have measured the non-local resistance of aluminum-iron spin-valve structures fabricated by e-beam lithography and shadow evaporation. The sample geometry consists of an aluminum bar with two or more ferromagnetic wires forming point contacts to the aluminum at varying distances from each other. In the normal state of aluminum, we observe a spin-valve signal which allows us to control the relative orientation of the magnetizations of the ferromagnetic contacts. In the superconducting state, at low temperatures and excitation voltages well below the gap, we observe a spin-dependent non-local resistance which decays on a smaller length scale than the normal-state spin-valve signal. The sign, magnitude and decay length of this signal is consistent with predictions made for crossed Andreev reflection (CAR).

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: Three groups of farmers on the Transvaal Highveld were compared: Full-time farmers, part-time farmers entering the industry with the aim of eventually becoming full-time farmers and persons intending to farm part-time on a permanent basis. Management indices based on production functions indicate that full-time farmers were most efficient entrepreneurs and those who intend to farm part-time permanently the least efficient. The general organisation of full-time farmers appears to be better than that of part-time farmers. The difference between the two groups of part-time farmers appears to be operational in nature. Those intending to become full-time farmers fared better in most individual enterprises than permanent part-time farmers.

description: Heavy quarkonium theory has seen significant progress over the past years. Not only has the community steadily improved the understanding of fully equilibrated quarkonium using first principles lattice QCD studies, but it has taken major steps towards developing a genuine dynamical understanding of quark-antiquark pairs immersed in a hot medium by embracing the paradigm of open quantum systems. We review recent developments, placing an emphasis on quarkonium real-time dynamics.

The Contribution of Different Supernova Populations to the Galactic Gamma-Ray Background

description: The contribution of Source Cosmic Rays (SCRs), accelerated and still confined in Supernova Remnants (SNRs), to the diffuse high energy \gr emission above 1 GeV from the Galactic disk is studied. The \grs produced by the SCRs have a much harder spectrum than those generated by the Galactic Cosmic Rays (GCRs). Extending a previous paper, a simple SNR population synthesis is considered and the Inverse Compton emission from the SCR electrons is evaluated in greater detail. Then the combined spectrum of \gr emission from the Galactic Supernova Remnant population is calculated and this emission at low Galactic latitudes is compared with the diffuse \gr emission observed by the EGRET and ground based instruments. The average contribution of SCRs is comparable to the GCR contribution already at GeV energies, due to Supernovae of types II and Ib exploding into the wind bubbles of quite massive progenitor stars, and becomes dominant at \gr energies above 100 GeV. At TeV energies the dominant contribution is from SCRs in SNRs that expand into a uniform interstellar medium. In fact, the sum of hadronic and Inverse Compton \grs would exceed the limits given by the existing experimental data, unless the confinement time $T_{SN}$, i.e. the time until which SNRs confine the main fraction of accelerated SCRs, is as small as $T_{SN}\sim 10^4$ yr and the typical magnetic field strength in SNRs as large as 30 $μ$G. Both situations are however possible as a result of field amplification through CR backreaction in the acceleration process. It is pointed out that accurate measurements of the low-latitude diffuse Galactic \gr spectrum at TeV-energies can serve as a unique consistency test for CR origin from the Supernova Remnant population as a whole.

description: The purpose of this article is to evaluate the present situation of farm management (FM) in South Africa in its professional context. The evolution of FM in the USA, the UK and Australia has been used as the norm to evaluate the progress of FM teaching and research in South Africa. In order to review the development of FM in South Africa over the past 60 years, the period has been divided into three phases. The outstanding feature of FM in Phase I (1925 - 1950) was its multidisciplinary nature in contrast with the dominating role of production economics in FM in Phase 11 (1950 - 1970). The last 15 years (Phase III) in the evolution of FM is typified by the greater role played by management science in FM. As in the USA, the UK and Australia, it can be said that FM is regarded basically as FM economics (narrower approach) in South Africa today, but attempts are being made to integrate the various disciplines. As far as FM teaching is concerned, the integration is accomplished in two alternative ways. In contrast to the case in the USA, FM research was given the highest priority than other fields of agricultural economics during Phase III. The progress made in FM in SA over the past 15 years was satisfactory on the whole. However, the progress was far from ideal, because there were no strong international leaders in FM during this period. FM will remain a key field of agricultural economics in future, but it can be expected that the relative importance of FM will decline as it did in the USA.

description: A recent experiment [Nature Physics 10, 1 (2019)] has realized a dynamical gauge system with $\mathbb{Z}_2$ gauge symmetry in a double-well potential. In this work we propose a method to generalize this model from a single double well to a one-dimensional chain. We show that although there is no disordered potential in the original model, the phenomenon of many-body localization can occur. The key ingredient is that different symmetry sectors with different local gauge charges play the role of different disorder configurations, which becomes clear after exactly mapping our model to a transverse Ising model in a random longitudinal field. We show that both the ergodic regime and the many-body localized regime exist in this model from four different metrics, which include level statistics, volume law versus area law of entanglement entropy of eigenstates, quench dynamics of entanglement entropy and physical observables.

description: Superconducting double transition in PrOs_4_Sb_12 is investigated by analyzing the anisotropy of the upper critical field H_c2 in the ab-plane, and the possible pairing state is discussed. When mixing due to gradient coupling is active, the twofold-symmetric component is necessarily induced in the fourfold symmetric phase, leading to the twofold oscillation of H_c2, contrary to the experimental result. To avoid the mixing effect, the weak spin-orbit coupling triplet pairing state is considered as a likely pairing function, where time-reversal symmetry is broken.

description: The accuracy of Burr approximations of critical values and p-values is evaluated for the usual tests of the general linear regression model. These include tests for coefficients and autocorrelation and heteroscedasticity, based both on standard distributions and those for which the distribution is unknown. The results suggest that the Burr approximations are reasonably accurate and should prove useful both in applied research and in teaching.

description: The measurement-device-independent quantum key distribution (MDI-QKD) protocol plays an important role in quantum communications due to its high level of security and practicability. It can be immune to all side-channel attacks directed on the detecting devices. However, the protocol still contains strict requirements during state preparation in most existing MDI-QKD schemes, e.g., perfect state preparation or perfectly characterized sources, which are very hard to realize in practice. In this letter, we investigate uncharacterized MDI-QKD by utilizing a three-state method, greatly reducing the finite-size effect. The only requirement for state preparation is that the state are prepared in a bidimensional Hilbert space. Furthermore, a proof-of-principle demonstration over a 170 km transmission distance is achieved, representing the longest transmission distance under the same security level on record.

description: There is an argument that policing practices exacerbate HIV risk, particularly for female sex workers. Interventions that mobilize sex workers to seek changes in laws and law enforcement practices have been prominent in India and have received considerable scholarly attention. Yet, there are few studies on the strategies sex worker advocates use to modify police behavior or the struggles they face in challenging state institutions. This paper draws upon contemporary theories of governance and non-state regulation to analyze the evolving strategies of an HIV prevention non-governmental organization (NGO) and female sex worker community-based organizations (CBOs) to reform police practices in southern India. Using detailed ethnographic observations of NGO and CBO activities over a two year period, and key informant interviews with various actors in the sex trade, this paper shows how a powerless group of marginalized and stigmatized women were able to leverage the combined forces of community empowerment, collective action and network-based governance to regulate a powerful state actor, and considers the impact of the advocacy strategies on sex worker well-being.

description: The electronic structure of the first Pu based superconductor PuCoGa5 is explored using photoelectron spectroscopy and a novel theoretical scheme. Exceptional agreement between calculation and experiment defines a path forward for understanding electronic structure aspects of Pu based materials. The photoemission results show two separate regions of 5f electron spectral intensity, one at the Fermi energy and another centered 1.2 eV below the Fermi level. The results for PuCoGa5 clearly indicate 5f electron behavior on the threshold between localized and itinerant. Comparisons to delta phase Pu metal show a broader framework for understanding the fundamental electronic properties of the Pu 5f levels in general within two configurations, one localized and one itinerant.

title: A Cockney Catullus: the reception of Catullus in the Romantic era
Creators: name: Stead, Henry
Publisher: name: The Open University
Year: 2012

description: This thesis explores the reception of Catullus in Britain between 1780 and 1830. After a brief summary of attitudes towards classical culture in Romantic Britain, the first chapter begins by examining the key translations of Catullus in the English language, by John Nott and George Lamb. Chapter one ends with a discussion of the translations of Catullus 64 by Charles Abraham Elton and Frank Sayers. The second chapter addresses the Catullan receptions of Wordsworth, Byron and Thomas Moore. The third is focused on the "uses" of Catullus' text by 'the King of the Cockneys,' Leigh Hunt. Chapter four returns to Romantic engagements with Catullus 64, identifying a symbolic allegory in the Cockney treatment of the Ariadne myth. The thesis ends with an exploration of the textual relationship between Catullus and John Keats.

description: There are many different brands associated with the University of British Columbia (UBC) food service system. A brand is defined as “a distinctive kind or variety” (Steinmetz, 2002). Some examples of branding at UBC are the use of Coca-Cola cold beverages on campus, different franchise outlets, and the selling of Starbucks coffee. The impact of franchises on the sustainability of the UBC campus is addressed in this analytical report. A franchise is defined as “the right granted to an individual or group to market a company’s goods or services in a particular territory” (Babcock, 1986). Generally, the owner of a franchise retail outlet must purchase the right to use the company name, purchase products from the company, and pay royalties to the company. While there are financial commitments associated with franchises, the use of a company’s name often provides selling power due to consumer recognition. The impacts of franchises are examined by comparing franchises with non-franchises. Currently, all franchises are operated by UBC Food Services (UBCFS); thus the comparison was made between food outlets operated by UBCFS only. In particular, Bread Garden was compared to Trekkers for specific analyses because both cafeteria-style outlets serve similar foods in a comparable atmosphere. UBCFS is a self-funded operation that has food service outlets throughout the UBC campus. Its mission is to “promote and support the university and the greater community by providing good food, friendly services, and value, while maintaining financial integrity through dedicated and skilled employees.” (UBCFS, 1997). In addition to UBCFS outlets, UBCFS has been introducing different franchises to the UBC campus since 1998 (UBCFS, 2001).

description: Community Based HIV/AIDS Research: Guidelines for Successful Partnerships was created to highlight local models of community based research (CBR). The Center for Interdisciplinary Research on AIDS (CIRA) Community Research (CR) Core developed the Guidelines with assistance from community partners and scientists through a series of workshops to reflect on and document local models of CBR that represented some successful community based HIV/AIDS initiatives conducted in Connecticut since the start of the epidemic. The Guidelines summarize the broad themes that emerged during the course of the workshops, including various strengths and weaknesses of the collaborations in order to distinguish common features contributing to the formation, success, and continued maintenance of CBR. The Guidelines address the components needed to establish strong, practical, productive collaborations between researchers and communities in order to yield outcomes likely to meet the objectives of all parties while maintaining best practices in public health research. It also identifies potential gaps that should be addressed in future research efforts. We anticipate that research endeavors utilizing CBR techniques can and will benefit from reviewing and integrating principles from the Guidelines. Each case study describes specific strengths and weaknesses associated with conducting CBR based on their particular research collaboration. However, there were recurrent themes across all of the models. The workshop on challenging collaborations and the IDU research participant workshop added further depth to our understanding of the collaborative research process of CBR. The following are our recommended Guidelines for Successful Partnerships on Community Based HIV/AIDS Research.
Isometries from gauge transformations

description: In four dimensions one can use the chiral part of the spin connection as the main object that encodes geometry. The metric is then recovered algebraically from the curvature of this connection. We address the question of how isometries can be identified in this "pure connection" formalism. We show that isometries are recovered from gauge transformation parameters satisfying the requirement that the Lie derivative of the connection along a vector field generating an isometry is a gauge transformation. This requirement can be rewritten as a first order differential equation involving the gauge transformation parameter only. Once a gauge transformation satisfying this equation is found, the isometry generating vector field is recovered algebraically. We work out examples of the new formalism being used to determine isometries, and also prove a general statement: a negative definite connection on a compact manifold does not have symmetries. This is the precise "pure connection" analog of the well-known Riemannian geometry statement that there are no Killing vector fields on compact manifolds with negative Ricci curvature.

description: We selected a sample of eight bright unobscured (at least at the iron line energy) Seyfert Galaxies observed simultaneously by XMM-Newton and BeppoSAX, taking advantage of the complementary characteristics of the two missions. The main results of our analysis can be summarized as follows: narrow neutral iron lines are confirmed to be an ubiquitous component in Seyfert spectra; none of the analyzed sources shows unambiguously a broad relativistic iron line; all the sources of our sample (with a single exception) show the presence of a Compton reflection component; emission lines from ionized iron are observed in some sources; peculiar weak features around 5-6 keV (possibly arising from rotating spots on the accretion disk) are detected in two sources. The scenario emerging from these results strongly requires some corrections for the classical model of reprocessing from the accretion disk. As for materials farther away from the Black Hole, our results represent a positive test for the Unification Model, suggesting the presence of the torus in (almost) all sources, even if unobscured.

description: This paper proposes the use of a generalisation of the Logistic distribution, the Burr Type II distribution, as the error structure in a Type I (Standard) Tobit model. The use of the Burr II is motivated through both an heterogeneity argument and by noticing the need for potentially non-symmetric distributions in Tobit models. Tests for symmetry (the Logistic distribution) and its implied heterogeneity are also proposed. Finally the model is estimated using Australian data on alcohol expenditure.

description: Desirable features of a tax on agricultural land are that it is not a disincentive to effort, it does not distort resource allocation, it does not increase food prices and evasion is not possible. A land tax on these grounds is superior to an income tax. The tax, however, must be acceptable to the community. The administration of a land tax is costly as all properties need to be appraised individually and regularly. The rise in expenses and function of government has made such a tax inadequate to finance national government expenditure and land taxes are usually used to finance local government expenditure. Currently agriculture is heavily subsidised in developed countries which means that tax money is rechannelled into agriculture, after a portion of it is wasted (lost) in the administration of tax and subsidy schemes. More attention needs to be given to eliminating subsidies that do not meet efficiency and equity goals rather than embarking on new forms of taxation. In this context a subsidy on labour qualifies, whereas a subsidy on the purchase of land is an economic waste, as the subsidy becomes capitalised in higher land values.

description: Community Based HIV/AIDS Research: Guidelines for Successful Partnerships was created to highlight local models of community based research (CBR). The Center for Interdisciplinary Research on AIDS (CIRA) Community Research (CR) Core developed the Guidelines with assistance from community partners and scientists through a series of workshops to reflect on and document local models of CBR that represented some successful community based HIV/AIDS initiatives conducted in Connecticut since the start of the epidemic. The Guidelines summarize the broad themes that emerged during the course of the workshops, including various strengths and weaknesses of the collaborations in order to distinguish common features contributing to the formation, success, and continued maintenance of CBR. The Guidelines address the components needed to establish strong, practical, productive collaborations between researchers and communities in order to yield outcomes likely to meet the objectives of all parties while maintaining best practices in public health research. It also identifies potential gaps that should be addressed in future research efforts. We anticipate that research endeavors utilizing CBR techniques can and will benefit from reviewing and integrating principles from the Guidelines. Each case study describes specific strengths and weaknesses associated with conducting CBR based on their particular research collaboration. However, there were recurrent themes across all of the models. The workshop on challenging collaborations and the IDU research participant workshop added further depth to our understanding of the collaborative research process of CBR. The following are our recommended Guidelines for Successful Partnerships on Community Based HIV/AIDS Research.

description: Предметом исследования является восприятие в российском обществе образа России, созданного британским писателем С. Грэхемом в годы Первой мировой войны. Он отстаивал самобытность России, а ее силу видел в сохранении религиозно-консервативных устоев. Подобный подход вызвал серьезную критику со стороны представителей буржуазно-демократических кругов, которые считали, что такой образ России не только не соответствует действительности, но и вредит союзническим отношениям. Вредным такой взгляд для самой России считал известный писатель М. Горький.
description: The article examines the Russian society’s perception of the image of Russia created by the British traveller and writer S. Graham during the First World War. He advocated originality of Russia and saw her power in conservative traditions and deep religiosity. Although in bourgeois-democratic circles his writings were heavily criticized because his perception of Russia was wrong and caused damage to Russian-British relationship. A famous writer Maxim Gorky also considered such image to be bad for Russia.
The peculiar circumstellar environment of NGC2024-IRS2

description: We re-examine the nature of NGC2024-IRS2 in light of the recent discovery of the late O-type star, IRS2b, located 5 arcsec from IRS2. Using L-band spectroscopy, we set a lower limit of Av = 27.0 mag on the visual extinction towards IRS2. Arguments based on the nature of the circumstellar material, favor an Av of 31.5 mag. IRS2 is associated with the UCHII region G206.543-16.347 and the infrared source IRAS 05393-0156. We show that much of the mid-infrared emission towards IRS2, as well as the far infrared emission peaking at ~ 100 micron, do not originate in the direct surroundings of IRS2, but instead from an extended molecular cloud. Using new K-, L- and L'-band spectroscopy and a comprehensive set of infrared and radio continuum measurements from the literature, we apply diagnostics based on the radio slope, the strength of the infrared hydrogen recombination lines, and the presence of CO band-heads to constrain the nature and spatial distribution of the circumstellar material of IRS2. Using simple gaseous and/or dust models of prescribed geometry, we find strong indications that the infrared flux originating in the circumstellar material of IRS2 is dominated by emission from a dense gaseous disk with a radius of about 0.6 AU. At radio wavelengths the flux density distribution is best described by a stellar wind recombining at a radius of about 100 AU. Although NGC2024/IRS2 shares many similarities with BN-like objects, we do not find evidence for the presence of a dust shell surrounding this object. Therefore, IRS2 is likely more evolved.

description: A quantum integrability index was proposed in \cite{KMS}. It systematizes the Goldschmidt and Witten's operator counting argument \cite{GW} by using the conformal symmetry. In this work we compute the quantum integrability indexes for the symmetric coset models ${SU(N)}/{SO(N)}$ and $SO(2N)/{SO(N)\times SO(N)}$. The indexes of these theories are all non-positive except for the case of ${SO(4)}/{SO(2)\times SO(2)}$. Moreover we extend the analysis to the theories with fermions and consider a concrete theory: the $\mathbb{CP}^N$ model coupled with a massless Dirac fermion. We find that the indexes for this class of models are non-positive as well.

description: The prevalence of HIV infection in correctional settings is several-fold higher than found in community settings. New approaches to identifying HIV infection among prisoners are urgently needed. In order to determine the HIV seroprevalence and to identify the correlates of HIV infection among female prisoners, an anonymous, but linked HIV serosurvey was conducted at Connecticut’s sole correctional facility for women (census=1,100). After removing all individual identifiers for inmates’ standardized clinical and risk behavior information, data are linked by a third source to blinded HIV-testing information by a third party. This three-step sequential process allows for anonymous HIV testing that can still be linked with deidentified clinical and behavioral data. Of the 3,315 subjects with complete information, 250 (7.5%) were HIV+. Of these, 157 (63%) selfreported being HIV+. Using multiple logistic regression analysis, having sex with a known HIV+ person [adjusted odds ratio (AOR)=9.1] and injection drug use (AOR=6.1) were the most highly correlated risk factors for HIV, whereas leukopenia (AOR=9.4) and hypoalbuminemia (AOR=7.2) were the most significant laboratory markers. Other independent correlates of HIV included self-report of syphilis (AOR=1.9) or genital herpes infection (AOR=2.7) and being Black (AOR=2.1) or Hispanic (AOR=2.2). The prevalence of HIV and HIV-risk behaviors is high among incarcerated women. Existing voluntary HIV counseling and testing programs do not completely target high-risk groups who remain part of the evolving epidemic. Defined demographic, behavioral, and clinical assessments may provide useful information for encouraging targeted counseling and testing. Newer targeted approaches merit further study to determine the effectiveness of this approach. Alternative methods of facilitating more widespread HIV testing, such as saliva tests, rapid serologic tests, and more routine testing in high HIV-prevalence areas should be considered both for clinical and for public health benefits.
