description: We present a multi-frequency study of eclipse properties of a transitional redback millisecond pulsar J1227$-$4853 discovered in 2014 with the GMRT. Emission from this pulsar is eclipsed at 607 MHz for about 37% of its orbit around the superior conjunction. We observe eclipse ingress and egress transition which last 12% and 15% of its orbit respectively, resulting in only 36% of the orbit being unaffected by eclipsing material. We report an excess dispersion measure (DM) at eclipse boundaries of 0.079(3) pc cm$^{-3}$ and the corresponding electron column density (N$_e$) is 24.4(8) x 10$^{16}$ cm$^{-2}$. Simultaneous timing and imaging studies suggests that the eclipses in J1227$-$4853 are not caused by temporal smearing due to excess dispersion and scattering but could be caused by removal of pulsar flux due to cyclotron absorption of the pulsed signal by intra-binary material constraining the companion's magnetic field. Additionally, near inferior conjunction at orbital phase 0.71 and 0.82 the pulsed emission is significantly delayed which is associated with a fading of the pulsed and continuum flux densities. At orbital phase $\sim$0.82, we measure a change in DM of 0.035(3) pc cm$^{-3}$ and N$_e$ of 10.8(8) x 10$^{16}$ cm$^{-2}$ associated with a dimming of up to $\sim$30% of the peak flux density. Such flux fading around a fixed orbital phase is not reported for other eclipsing binaries. Moreover, this event around inferior conjunction could be caused by absorption of pulsed signal by fragmented blobs of plasma generated from mass loss through the L2 Lagrangian point.

description: We present early time high-resolution (VLT/UVES) and late time low-resolution (VLT/FORS) optical spectra of the normal type Ia supernova, SN 2001el. The high-resolution spectra were obtained at -9 and -2 days to allow the detection of narrow hydrogen and/or helium emission lines from the circumstellar medium of the SN. No such lines were detected, and we therefore use photoionisation models to derive upper limits of 9x10^-6 Msun/yr and 5x10^-5 Msun/yr for the mass loss rate from the progenitor system assuming velocities of 10 km/s and 50 km/s, respectively, for a wind extending to outside at least a few x 10^15 cm away from the SN explosion site. These limits exclude a symbiotic star in the upper mass loss rate regime from being the progenitor of SN 2001el. The low resolution spectrum was obtained in the nebular phase of the SN, 400 days after the maximum light, to search for any hydrogen rich gas originating from the SN progenitor system. However, we see no signs of Balmer lines in our spectrum. Therefore, we model the late time spectra to derive an upper limit of ~0.03 Msun for solar abundance material present at velocities lower than 1000 km/s within the SN explosion site. According to simulations of Marietta et al. (2000) this is less than the expected mass lost by a subgiant, red giant or main sequence secondary star at a small binary separation as a result of the SN explosion. Finally, we discuss the origin of high velocity Ca II lines. We see both the CaII IR triplet and the H&K lines in the -9 days spectrum at a very high velocity of up to 34000 km/s. The spectrum also shows a flat-bottomed Si II `6150 A' feature similar to the one previously observed in SN 1990N at -14 days. We compare these spectral features to those observed in SNe 1984A and 1990N at even higher velocities.

description: Taking seriously the interpretation of black hole entropy as the logarithm of the number of microstates, we argue that thermal gravitons may undergo a phase transition to a kind of black hole condensate. The phase transition proceeds via nucleation of black holes at a rate governed by a saddlepoint configuration whose free energy is of order the inverse temperature in Planck units. Whether the universe remains in a low entropy state as opposed to the high entropy black hole condensate depends sensitively on its thermal history. Our results may clarify an old observation of Penrose regarding the very low entropy state of the universe.

Arbitrary polarization conversion for pure vortex generation with a single metasurface

Publisher: name: arXiv
Year: 2020
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: The purity of an optical vortex beam depends on the spread of its energy among different azimuthal and radial modes. The smaller is this spread, the higher is the vortex purity and the more efficient are its creation and detection. There are several methods to generate vortex beams with well-defined orbital angular momentum but only few exist allowing to select a pure radial mode. These typically consist of many optical elements with rather complex arrangements, including active cavity resonators. Here we show that it is possible to generate pure vortex beams using a single metasurface plate in combination with a polarizer. We generalize an existing theory of independent phase and amplitude control with birefringent nanopillars considering arbitrary input polarization states. The high purity, sizeable creation efficiency and impassable compactness make the presented approach a powerful complex amplitude modulation tool for pure vortex generation, even in the case of large topological charges.

description: We present a new library of integrated spectra of 40 Galactic globular clusters, obtained with the Blanco 4-m telescope and the R-C spectrograph at the Cerro Tololo Interamerican Observatory. The spectra cover the range ~ 3350 -- 6430 A with ~ 3.1 A (FWHM) resolution. The spectroscopic observations and data reduction were designed to integrate the full projected area within the cluster core radii in order to properly sample the light from stars in all relevant evolutionary stages. The S/N values of the flux-calibrated spectra range from 50 to 240/A at 4000 A and from 125 to 500/A at 5000 A. The selected targets span a wide range of cluster parameters, including metallicity, horizontal-branch morphology, Galactic coordinates, Galactocentric distance, and concentration. The total sample is thus fairly representative of the entire Galactic globular cluster population and should be valuable for comparison with similar integrated spectra of unresolved stellar populations in remote systems. For most of the library clusters, our spectra can be coupled with deep color-magnitude diagrams and reliable metal abundances from the literature to enable the calibration of stellar population synthesis models. In this paper we present a detailed account of the observations and data reduction. The spectral library is publicly available in electronic format from the National Optical Astronomical Observatory website.

description: The natural variation in climate around the world means that periods of severe shortfall of rainfall are inevitable, and some times occur on a large geographical scale. Human settlements have adapted to this reality in many different ways, including the development of agricultural systems that feature variously robust aspects in the face of drought. As climates change under the influence of modified atmospheric composition, it seems likely that many parts of the world will face increased incidence of drought and thus more challenging tasks for farm managers, managers of non- farm enterprises that are sensitive to drought, national policy makers and, last but not least, households in rural areas that are close to subsistence levels even in non-drought seasons. The agricultural economics profession must continue to contribute to better dealing with all these challenges.

description: By decomposing the Coulomb interaction into a long distance component appropriate for mean-field theory, and a nonmean-field short distance component, we compute the counterion density near a charged surface for all values of the counterion coupling parameter. A modified strong-coupling expansion that is manifestly finite at all coupling strengths is used to treat the short distance component. We find a nonperturbative correction related to the lateral counterion correlations that modifies the density at intermediate coupling.

description: The objective of this paper is to examine the role of the factors expected to influence the success potential of small holder irrigation projects as they apply in the South African context. The study was conducted in six smallholder irrigation schemes in three provinces namely: Eastern Cape, Limpopo and Mpumalanga. To determine the farmers' potential success (dependent variable), a cluster analysis was conducted yielding two groups of farmers - the less successful and more successful. The principal component regression (PCR) tool was used to analyse the data and deal with the problem of multicollinearity, transforming the explanatory variables into principal component estimators. There were fourteen explanatory variables. Out of the nine statistically significant variables, seven have the expected sign. These are infrastructure, market access, research & development, off-farm income and extension (significant at the 1% level) while planning and transport are significant at the 5% level. The study has shown which areas should receive specific attention to improve the success potential in South African smallholder irrigation projects.

description: Microfluidic paper combines pump-free water transport at low cost with a high degree of sustainability, as well as good availability of the paper-forming cellulosic material, thus making it an attractive candidate for point-of-care (POC) analytics and diagnostics. Although a number of interesting demonstrators for such paper devices have been reported to date, a number of challenges still exist, which limit a successful transfer into marketable applications. A strong limitation in this respect is the (unspecific) adsorption of protein analytes to the paper fibers during the lateral flow assay. This interaction may significantly reduce the amount of analyte that reaches the detection zone of the microfluidic paper-based analytical device (µPAD), thereby reducing its overall sensitivity. Here, we introduce a novel approach on reducing the nonspecific adsorption of proteins to lab-made paper sheets for the use in µPADs. To this, cotton linter fibers in lab-formed additive-free paper sheets are modified with a surrounding thin hydrogel layer generated from photo-crosslinked, benzophenone functionalized copolymers based on poly-(oligo-ethylene glycol methacrylate) (POEGMA) and poly-dimethyl acrylamide (PDMAA). This, as we show in tests similar to lateral flow assays, significantly reduces unspecific binding of model proteins. Furthermore, by evaporating the transport fluid during the microfluidic run at the end of the paper strip through local heating, model proteins can almost quantitatively be accumulated in that zone. The possibility of complete, almost quantitative protein transport in a µPAD opens up new opportunities to significantly improve the signal-to-noise (S/N) ratio of paper-based lateral flow assays.

description: The superconducting gap structure of recently discovered heavy fermion CePt_3Si without spatial inversion symmetry was investigated by thermal transport measurements down to 40 mK. In zero field a residual T-linear term was clearly resolved as T-> 0, with a magnitude in good agreement with the value expected for a residual normal fluid with a nodal gap structure, together with a T^2-dependence at high temperatures. With an applied magnetic fields, the thermal conductivity grows rapidly, in dramatic contrast to fully gapped superconductors, and exhibits one-parameter scaling with T/sqrt{H}. These results place an important constraint on the order parameter symmetry, that is CePt_3Si is most likely to have line nodes.

Spectral Formation in X-Ray Pulsar Accretion Columns

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: We present the first self-consistent model for the dynamics and the radiative transfer occurring in bright X-ray pulsar accretion columns, with a special focus on the role of the shock in energizing the emerging X-rays. The pressure inside the accretion column of a luminous X-ray pulsar is dominated by the photons, and consequently the equations describing the coupled radiative-dynamical structure must be solved simultaneously. Spectral formation in these sources is therefore a complex, nonlinear phenomenon. We obtain the analytical solution for the Green's function describing the upscattering of monochromatic radiation injected into the column from the thermal mound located near the base of the flow. The Green's function is convolved with a Planck distribution to model the X-ray spectrum resulting from the reprocessing of blackbody photons produced in the thermal mound. These photons diffuse through the infalling gas and eventually escape out the walls of the column, forming the observed X-ray spectrum. We show that the resulting column-integrated, phase-averaged spectrum has a power-law shape at high energies and a blackbody shape at low energies, in agreement with the observational data for many X-ray pulsars.

description: Although the key concept of a quota is simple - to set a limit on production - the market and welfare implications of operating a quota system are relatively complex. The purpose of the analysis reported in this paper is to address two aspects relevant to an evaluation of quota systems. First, quota is typically contingent on the existence of another policy, namely market price support, and as such, interacts with other policy tools in pursuing defined policy objectives. The paper examines analytically and empirically the trade-offs that exist among the individual policy tools for a given policy objective. Second, the paper discusses some important welfare effects of quota systems that are not often considered in the literature. It illustrates that if parts of the primary factors of production are not owned by the milk farmer and prices for purchase farm inputs are not perfectly elastic the conventionally used measure of producer surplus may understate net benefits to farmers of a quota system. Under the quota, the share of benefits flowing to owners of farm resources is magnified at the expense of input suppliers and the rent accruing to quota reduces the surplus accruing to traditional resources. A fact that aggravates the vested interests inherent to a quota.

description: In this paper, the design of water markets for the management of irrigation-induced salinity in Australia is addressed. Indeed, this setting exhibits complex interactions between the different features of the resource water. Quality, quantity of surface and ground-water interact in ways that produce coupled environmental externalities. It is then difficult to design efficient policy instruments to tackle all the issues at stake. This paper provides a preliminary analysis of three types of water market mechanisms, involving diversion rights and recharge rights.

description: Quantum algorithms may be described by sequences of unitary transformations called quantum gates and measurements applied to the quantum register of n quantum bits, qubits. A collection of quantum gates is called universal if it can be used to construct any n-qubit gate. In 1995, the universality of the set of one-qubit gates and controlled NOT gate was shown by Barenco et al. using QR decomposition of unitary matrices. Almost ten years later the decomposition was improved to include essentially fewer elementary gates. In addition, the cosine-sine matrix decomposition was applied to efficiently implement decompositions of general quantum gates. In this chapter, we review the different types of general gate decompositions and slightly improve the best known gate count for the controlled NOT gates to (23/48)4^n in the leading order. In physical realizations, the interaction strength between the qubits can decrease strongly as a function of their distance. Therefore, we also discuss decompositions with the restriction to nearest-neighbor interactions in a linear chain of qubits.

Peer sexual harrassment : subtitle a social determinant of adolescent health?
Creators: name: Dahinten, Virginia Susan
Publisher: name: University of British Columbia
Year: 2009

description: The aim of this study was to expand our understanding of the experiences and health effects of school-based, peer sexual harassment among adolescents. The primary objective was to test a theoretical model of causal relationships between sexual harassment and psychological, physical, and behavioural health outcomes among female adolescents. A sub-objective was to examine the incidence and appraisal of peer sexual harassment by gender. The study employed a retrospective cross-sectional survey design. Data were obtained from male and female high school students in grades 9 through 11; participants were recruited from 12 schools in British Columbia and New Brunswick. Data from all respondents (N = 565) were used to describe the students' sexual harassment experiences, although investigation into the relationships between harassment and health was conducted only for the female respondents (n = 348). Structural equation modelling was used to test the proposed theoretical model. There were four major findings. First, sexual harassment was found to be pervasive among both male and female students in grades 9 through 11. However, female students experience a greater variety of harassment behaviours and more frequent harassment than male students, and they report being more upset by the harassment that they receive. Second, both male and female students report that, in general, gender harassment is more upsetting than unwanted sexual advances. Third, female students who experience more frequent and more upsetting sexual harassment also experience worse health outcomes. Sexual harassment was found to explain a good deal of the variance in negative health outcomes over and above the effects of other school-based stressors. Fourth, although female students are more likely to engage in behavioural coping responses as sexual harassment increases in frequency or degree of threat, these coping strategies do not necessarily mediate or reduce the harmful effects of sexual harassment. The results of this study suggest that we should be wary about trivializing the possible consequences of sexual harassment among adolescents, even though adults might perceive some of the incidents to be mundane experiences. The implications of these findings for school health programs and other preventive interventions are discussed.

description: A combination of quantitative and qualitative method was used to analyse the determinants of school completion/dropout of children from primary education. A Cox box proportional hazard model was used analyse the survival of children in primary education. The findings have important implications for the formulation and revising Ethiopian Poverty Reduction Strategy Paper. While the policy focus of the 1996-initiated ESDP and the SDPRP (2002-5) on increasing educational access for all has been broadly successful, children from poor and/or highly indebted families still face significant constraints because they have to contribute to household survival through paid and unpaid work. It is therefore imperative to increase efforts to improve the livelihood options of the poor, including greater income generation opportunities, particularly in rural areas and for women. However, such strategies need to be child sensitive. For instance, income generating opportunities for women should simultaneously be accompanied by community childcare systems in order to prevent older children from shouldering their mother's childcare burden.

description: E-commerce is penetrating agriculture, particularly for selling products directly to consumers. The wine industry is a case in point. The industry has long-term experience in direct marketing. Many wineries welcome patrons at their premises for wine tasting and for selling wine to them. Moreover, where the practice is allowed, shipping wine directly to consumers without the assistance of trade intermediaries is a significant sales channel. E-commerce was adopted early in the wine industries of wired high-income countries and the wine industry provides an opportunity for studying the adoption, use, and impact of e-commerce. Moreover, because e-commerce has not spread evenly through all branches of agriculture, lessons learned from the wine industry may provide useful insights for entrepreneurs and policy makers concerned with sections of agriculture or the food industry where e-commerce adoption lags behind. The specific objectives of the dissertation research project which we report here therefore were: (1) to assess the extent of e-commerce diffusion in the wine industries of Australia, California, Germany; (2) to identify e-commerce practices used by wineries for marketing wine; (3) to explain differences in wineries' e-commerce practices, and (4) to derive insights and implications for sections of agriculture that lag behind in ecommerce adoption.

description: We present the HI observations of 94 flat spiral galaxies from RFGC (the Revised Flat Galaxy Catalog) and 14 galaxies from 2MFGC (the 2MASS selected Flat Galaxy Catalog) performed with the 100-m radio telescope in Effelsberg (Germany). HI fluxes, heliocentric radial velocities, and HI line widths are given for 65 detected galaxies. We present a mosaic of HI profiles. We calculated some of the global parameters of the galaxies and analyzed the linear correlations between them. The ratios of the total (indicative) masses of the galaxies to their luminosities lie within the range 0.4 with a mean of 3.8 ($M_{\sun}/L_{\sun}$), and the mean mass fraction of neutral hydrogen is 13%. Upper limits are given for the radio fluxes from 43 undetected galaxies.

description: Economic reform in the Central and Eastern European countries in the 1980s helped transform the structure and volume of agricultural production, consumption and trade, and resulted in significant agricultural productivity improvements. However, there are large differences among the transition countries in the magnitude and direction of these changes. The main objective of this study is to measure and compare the levels and trends in agricultural productivity in transition countries with those of the European Union (EU) countries making use of the most recent data available from the Food and Agriculture Organization (FAO). This study employs a parametric distance function approach to measure Malmquist productivity index as well as the magnitude and direction of technical change. The Malmquist productivity index is decomposed into technical change (TC), technical efficiency change (TEC) and scale efficiency change (SEC) in which TC is decomposed into input- and output- biased TC. These measures provide insightful information for researchers in designing policies to achieve a high growth rate in transition countries.

description: We report on two sub-band transport in double gate SiO$_2$-Si-SiO$_2$ quantum well with 14 nm thick Si layer at 270 mK. At symmetric well potential the experimental sub-band spacing changes monotonically from 2.3 to 0.3 meV when the total density is adjusted by gate voltages between $\sim 0.7\times 10^{16}$ $-3.0\times 10^{16}$ m$^{-2}$. The conductivity is mapped in large gate bias window and it shows strong non-monotonic features. At symmetric well potential and high density these features are addressed to sub-band wave function delocalization in the quantization direction and to different disorder of the top and bottom interfaces of the Si well. Close to bi-layer/second sub-band threshold the non-monotonic behavior is interpreted to arise from scattering from localized band tail electrons.

description: Metastasis is one of the most significant independent risk factors that can negatively affect prostate cancer (PCa) patients. However, the exact mechanisms have not been fully elucidated. To illustrate the mechanisms underlying PCa metastasis, we conducted a series of integrated bioinformatics analyses. The essential genes involved in PCa metastasis were obtained by analyzing differentially expressed genes (DEGs) between metastatic PCa and localized PCa. Gene Ontology and KEGG pathway enrichment analysis were performed for functional annotation. Protein-protein interaction networks were constructed for hub gene selection. Three transcription factor genes (FOS, CENPA, and FOXM1) were identiﬁed by integrating the hub genes with human transcription factors from The Human Transcription Factors database. Moreover, expression validation and prognostic analysis of the three transcription factor genes were carried out on GEO, TCGA, GEPIA, and the Human Protein Atlas, respectively. Further verification showed that expression variation of the three transcription factor genes existed between metastatic PCa and localized PCa as well as between localized PCa and normal prostate. In addition, different expressions of the three transcription factor genes were associated with the prognosis of localized PCa. In summary, the three transcription factor genes can serve as potential prognostic biomarkers as well as therapeutic targets for PCa.

description: A simple method to deal with four dimensional Hamilton-Jacobi equation for null hypersurfaces is introduced. This method allows to find simple geometrical conditions which give rise to the failure of the WKB approximation on curved spacetimes. The relation between such failure, extreme blackholes and the Cosmic Censor hypothesis is briefly discussed.
