description: A crucial ingredient in population synthesis studies involving massive stars is the determination of whether they explode or implode in the end. While the final fate of a massive star is sensitive to its core structure at the onset of collapse, the existing binary population synthesis studies do not reach core-collapse. Instead, they employ simple prescriptions to infer their final fates without knowing the presupernova core structure. We explore a potential solution to this problem by treating the carbon-oxygen (CO) core independently from the rest of the star. Using the implicit hydrodynamics code KEPLER, we have computed an extensive grid of 3496 CO-core models from a diverse range of initial conditions, each evolved from carbon ignition until core-collapse. The final core structure, and thus the explodability, varies non-monotonically and depends sensitively on both the mass and initial composition of the CO-core. Although bare CO-cores are not perfect substitutes for cores embedded in massive stars, our models compare well both with MESA and full hydrogenic and helium star calculations. Our results can be used to infer the presupernova core structures from population synthesis estimates of CO-core properties, thus to determine the final outcomes based on the results of modern neutrino-driven explosion simulations. A sample application is presented for a population of Type-IIb supernova progenitors. All of our models are available at https://doi.org/10.5281/zenodo.3785377.

description: We investigate the microwave electrodynamic properties of a single superconducting thin film split-ring resonator (SRR). The experiments were performed in an all-Nb waveguide, with Nb wires and Nb SRRs. Transmission data showed a high-Q stopband for a single Nb SRR ($Q \sim 4.5\times10^4$ at 4.2 K) below $T_c$, and no such feature for a Cu SRR, or closed Nb loops, of similar dimensions. Adding SRRs increased the bandwidth, but decreased the insertion loss of the features. Placing the Nb SRR into an array of wires produced a single, elementary negative-index passband ($Q \sim 2.26\times10^4$ at 4.2 K). Changes in the features due to the superconducting kinetic inductance were observed. Models for the SRR permeability, and the wire dielectric response, were used to fit the data.

description: It is well known that spin angular momentum of light, and therefore that of photons, is directly related to their circular polarization. Naturally, for totally unpolarized light, polarization is undefined and the spin vanishes. However, for nonparaxial light, the recently discovered transverse spin component, orthogonal to the main propagation direction, is largely independent of the polarization state of the wave. Here we demonstrate, both theoretically and experimentally, that this transverse spin survives even in nonparaxial fields (e.g., tightly focused or evanescent) generated from a totally unpolarized light source. This counterintuitive phenomenon is closely related to the fundamental difference between the degrees of polarization for 2D paraxial and 3D nonparaxial fields. Our results open an avenue for studies of spin-related phenomena and optical manipulation using unpolarized light.

description: This paper examines the impact of transgenic technology adoption on varietal diversity. Transgenic pest-resistant varieties are hypothesized to reduce farmers’ demand for on-farm diversity through an act of substitution, as both serve as production risk reducing instruments. This adverse agro-biodiversity impact might be partially counteracted by an expanding seed sector, supplying a large number of transgenic varieties. The case of Bt cotton in India is taken for empirical illustration. The production function analyses show that both Bt technology and on-farm varietal diversity enhance yield, while reducing the production risk. With few Bt varieties available in the first years, technology adoption entailed a reduction in on-farm varietal diversity. This effect, however, was partially offset by more Bt varieties becoming available over time.

description: We present CCD BVI photometry of the old open cluster Berkeley 29, located in the anticentre direction. Using the synthetic Colour - Magnitude Diagrams technique we estimate at the same time its age, reddening, distance, and approximate metallicity using three types of stellar evolutionary tracks. The best solutions give: age=3.4 or 3.7 Gyr, (m-M)_0 = 15.6 or 15.8 with E(B-V) = 0.13 or 0.10, and metallicity lower than solar (Z=0.006 or 0.004), depending on the adopted stellar models. Using these derived values, Be 29 turns out to be the most distant open cluster known, with Galactocentric distance R_GC= 21.4 to 22.6 kpc. Hence, Be 29 qualitatively follows both the age-metallicity relation and the metal abundance gradient typical of Galactic disc objects. The cluster position and radial velocity, however, appear to link Be 29 to the family of the Canis Major debris.

description: We consider a baryogenesis scenario, where the difference of baryon (B) and lepton (L) number is conserved in such a way that the B-L asymmetry in the standard model sector is compensated by an asymmetry of opposite sign stored in the dark energy sector. Therefore, we introduce a toy-model in which a complex quintessence field carries a B-L asymmetry at late times. We determine the produced baryon asymmetry in the visible sector for a large range of initial conditions and find it easy to achieve a value of the observed order of magnitude. While the size of the produced baryon asymmetry depends on details of the underlying inflationary model, it turns out to be independent of the reheating temperature in many cases. We also discuss possible sources of instability like the formation of Q-Balls.

Pishkash II (location same as above), 28 September 2005, 1 sexually active ♂ ad. netted at the entrance of a small cave in a limestone gorge. The morphological identification of this species was confirmed by genetic analysis (A. Kiefer, pers. comm.).
 The two records of bats from the genus Plecotus (Lamani 1970) could not be assigned to any particular species because of the lack of a detailed description and measurements. For the supposed Pl. kolombatovici record from the Treni Cave, at the Micro Prespa Lake in Albania (24–25 September 2012), no evidence has been provided to support the species identification and exclusion of other Plecotus species (Scheffler et al. 2013). Plecotus kolombatovici has one of the smallest geographic ranges among the European bats; it has only been confirmed in Greece and along the Adriatic coast of Croatia (Đulić 1980; Spitzenberger et al. 2006). The supposed records from Bosnia and Herzegovina are based on external and cranial measurements (Đulić 1980; Červený and Kryštufek 1988) and apparently require confirmation with genetic methods. This new Albanian record indicates a wider occurrence of this species in the southwestern Balkans and its syntopic presence with Pl. austriacus.

description: This paper develops a stochastic model for estimating the probability density function of the Average Crop Revenue Election (ACRE), a revenue-based commodity support payment that is offered under the 2008 Farm Act as an alternative to the traditional suite of price-based commodity payments, that is, marketing loan benefits and counter-cyclical payments. We minimize the potential for miss-specification bias in the model by using nonparametric and semi-nonparametric approaches as specification checks in the model. Our simulation results show that adding ACRE revenue payments to gross revenue reduced the downside risk in revenue for corn, wheat, and soybean farmers in 2009 in the four locations examined, with reductions ranging from 4% to 25%. Integrating Federal crop insurance with ACRE lowered insurance premiums from 10% to 40%, depending on the crop and location. A utility maximization approach is used to assess potential moral hazard effects of ACRE, and suggest little potential impact on acreage in the Heartland.

description: Let X be a complex analytic manifold and D \subset X a free divisor. Integrable logarithmic connections along D can be seen as locally free {\cal O}_X-modules endowed with a (left) module structure over the ring of logarithmic differential operators {\cal D}_X(\log D). In this paper we study two related results: the relationship between the duals of any integrable logarithmic connection over the base rings {\cal D}_X and {\cal D}_X(\log D), and a differential criterion for the logarithmic comparison theorem. We also generalize a formula of Esnault-Viehweg in the normal crossing case for the Verdier dual of a logarithmic de Rham complex.

description: Let $\mathbf{M}_n$ be the Simpson compactification of twisted ideal sheaves $\mathcal{I}_{L,Q}(1)$ where $Q$ is a rank $4$ quardric hypersurface in $\mathbb{P}^n$ and $L$ is a linear subspace of dimension $n-2$. This paper calculates the intersection Poincaré polynomial of $\mathbf{M}_n$ using Kirwan's desingularization method. We obtain the intersection Poincaré polynomial of the moduli space for one-dimensional sheaves on del Pezzo surfaces of degree $\geq 8$ by considering wall-crossings of stable pairs and complexes.

description: In this study, the problem of automatically classifying pulmonary diseases, including the recently emerged COVID-19, from X-Ray images, is considered. While the spread of COVID-19 is increased, new, automatic, and reliable methods for accurate detection are essential to reduce the exposure of the medical experts to the outbreak. X-ray imaging, although limited to specific visualizations, may be helpful for the diagnosis. Deep Learning has proven to be a remarkable method to extract massive high-dimensional features from medical images. Specifically, in this paper, the state-of-the-art Convolutional Neural Network called Mobile Net is employed and trained from scratch to investigate the importance of the extracted features for the classification task. A large-scale dataset of 3905 X-Ray images, corresponding to 6 diseases is utilized for training MobileNet v2, which has been proven to achieve remarkable results in related tasks. The results suggest that training CNNs from scratch may reveal vital biomarkers related but not limited to the COVID-19 disease, while an overall classification accuracy of the seven classes reaches 87.66%. Besides, this method achieves 99.18% accuracy, 97.36% Sensitivity, and 99.42% Specificity in the detection of COVID-19.

description: China’s transition into a developed economy is driving changes in consumer preferences and demand for foods. To evaluate consumer preferences for U.S. pork in urban China, primary data were collected in two metropolitan areas- Beijing and Shanghai. Estimated logit models revealed that an individual’s age, shopping location and food safety concerns significantly influenced their willingness-to-pay for U.S. pork. A proportional linear model was developed to evaluate factors affecting purchasing behavior of western-style pork cuts vs. traditional Chinese cuts. Food safety concerns were linked to a previous lean-meat additive scare and a lack of consumer confidence on the Chinese food inspection system.

description: This study uses a unique firm-level dataset to examine how falling trade costs from 1993-2001 affected entry, exit, productivity, and exporting in the Korean manufacturing sector. We verify many of the predictions of recent heterogeneous-firm models of international trade. For example, falling trade costs reduced entry by new Korean firms, increased their probability of exit, and reduced the market share of surviving firms. We also find that small firms had a particularly high level of dynamism over the sample period. Small firms were more likely to enter and exit, and marginally more likely to gain market share, enter export markets for the first time, and improve their productivity.

description: Atmospheric retrievals are now a standard tool to analyze observations of exoplanet atmospheres. This data-driven approach quantitatively compares atmospheric models to observations in order to estimate atmospheric properties and their uncertainties. In this paper, we introduce a new retrieval package, the PHOENIX Exoplanet Retrieval Analysis (PETRA). PETRA places the PHOENIX atmosphere model in a retrieval framework, allowing us to combine the strengths of a well-tested and widely-used atmosphere model with the advantages of retrieval algorithms. We validate PETRA by retrieving on simulated data for which the true atmospheric state is known. We also show that PETRA can successfully reproduce results from previously published retrievals of WASP-43b and HD 209458b. For the WASP-43b results, we show the effect that different line lists and line profile treatments have on the retrieved atmospheric properties. Lastly, we describe a novel technique for retrieving the temperature structure and $e^{-}$ density in ultra-hot Jupiters using H$^{-}$ opacity, allowing us to probe atmospheres devoid of most molecular features with JWST.

Parents of adolescents : the relationship between parent involvement and parent efficacy
Creators: name: Amaral, Deborah
Publisher: name: University of British Columbia
Year: 2009

description: Several researchers have suggested that parent efficacy has greater influence on parent involvement than status variables. This study examined the relationship between parent involvement and parent efficacy among 377 parents in four high schools of one school district in British Columbia. Through a mail survey parents reported their involvement in their adolescent's learning and their self-efficacy for helping their children in school. The findings reveal a small but significant relationship between parent efficacy and parent involvement. The results demonstrated that parent involvement at home is greater than parent involvement at school. Multiple regression analyses demonstrated that parent efficacy explained more of the variation in parent involvement than the status variables; however, much of the variability associated with parent involvement is due to factors other than those specified in the model.

description: This paper investigates the pricing and vertical organization of differentiated products under imperfect competition. In a multiproduct context, a Cournot model is used to examine how substitution/complementarity relationships among products and vertical structures can affect the exercise of market power. This motivates a generalization of the Herfindahl-Hirschman index (termed VHHI) capturing how market concentration and vertical structures interact to influence prices of differentiated products. The analysis is applied to pricing of soybean seeds in the US over the period 2000-2007. The analysis considers two vertical structures employed by biotech firms: vertical integration and licensing. The econometric analysis finds evidence that vertical organization has significant effects on seed prices. These effects are found to vary depending on the institutional setup and the bundling of genetic material. The empirical evidence shows that complementarity and economies of scope can reduce the effects of market concentration on prices.

description: Since lattice strain and charge density affect various material properties of graphene, a reliable and efficient method is required for quantification of the two variables. While Raman spectroscopy is sensitive and non-destructive, its validity towards precise quantification of chemical charge doping has not been tested. In this work, we quantified in-situ the fractional frequency change of 2D and G peaks in response of charge density induced by sulfuric acid solution as well as native lattice strain. Based on the experimental data and theoretical corroboration, we presented an optical method that simultaneously determines strain and chemically-induced charge density for three popular excitation wavelengths of 457, 514 and 633 nm. In order to expedite intercalation of dopant species through the graphene-SiO2 substrates, dense arrays of nanopores were precisely generated in graphene by thermal oxidation. The nano-perforated graphene membrane system was robust for multiple cycles of doping and undoping processes, and will be useful in studying various types of chemical interactions with graphene.

description: We present new Very Long Baseline Interferometry observations of the LINER galaxy NGC 4278. The observations were taken with the Very Long Baseline Array (VLBA) and a single antenna of the Very Large Array (VLA) at 5 GHz and 8.4 GHz and have a linear resolution of <0.1 pc. Our radio data reveal a two sided structure, with symmetric S-shaped jets emerging from a flat spectrum core. We fit the jet brightness with gaussian components, which we identify from a previous observation taken five years before. By comparing the positions of the components in the two epochs, we measure motions between 0.45 +/- 0.14 and 3.76 +/- 0.65 mas, corresponding to apparent velocities < 0.2c, and to ages in the range 8.3 - 65.8 years. Assuming that the radio morphology is intrinsically symmetric and its appearance is governed by Doppler beaming effects, we find that NGC4278 has mildly relativistic jets (beta ~ 0.75), closely aligned to the line-of-sight (2 degrees < theta < 4 degrees). Alternatively, the source could be oriented at a larger angle and asymmetries could be related to the jet interaction with the surrounding medium. We also present new simultaneous VLA observations between 1.4 and 43 GHz, and a 5 GHz light curve between 1972 and 2003. The radio spectrum can be fit by a relatively steep power-law (alpha = 0.54). We find significant variability at 5 GHz. All these arguments indicate that the radiation from NGC 4278 is emitted via the synchrotron process by relativistic particles accelerated by a supermassive black hole. Despite a much lower power, this is the same process that takes place in ordinary radio loud AGNs.

description: The effect of advertising on market performance has been a long-standing debate. Advertising that increases the dispersion of consumers’ valuations for advertised goods raises the market power of firms, while advertising that decreases the dispersion of consumers’ valuations leads to narrower price-cost margins and superior performance in markets for advertised goods. Numerous challenges confound the empirical identification of advertising effects on market performance. This paper proposes a simple method that relies on the revealed preferences of firms participating in generic advertising programs. Generic advertising programs provide a unique window through which to observe advertising effects on market performance, because changes in the dispersion of consumers’ valuations systematically redistributes rents among firms according to observable characteristics on producer size. We examine producer attitudes towards generic advertising in the “Beef. It’s What’s for Dinner” campaign of the U.S. Beef Checkoff program and find the likelihood a producer favors an expansion of the advertising program increases in operating scale. This finding is consistent with advertising effects that have led to a decrease in the dispersion of consumers’ valuations for beef products and a commensurate increase in market performance.

description: We present a charge integration photon detector (CIPD) that enables the efficient measurement of photon number states at the telecom-fiber wavelengths with a quantum efficiency of 80% and a resolution less than 0.5 electrons at 1 Hz sampling. The CIPD consists of an InGaAs PIN photodiode and a GaAs JFET in a charge integration amplifier, which is cooled to 4.2 K to reduce thermal noise and leakage current. The charge integration amplifier exhibits a low noise level of 470 nV/Hz1/2. The dark count is as low as 500 electrons/hour.

description: Our paper looks at how price volatility in the Brazilian ethanol industry changes over time and across markets by using a new methodological approach suggested by Seo (2007). The main advantage of Seo’s proposal over previously existing methods is that it allows to jointly estimate the cointegration relationship between the price series investigated and the multivariate GARCH process. Our results suggest that crude oil prices not only influence ethanol price levels, but also their volatility. Increased volatility in crude oil markets results in increased volatility in ethanol markets. Ethanol prices, on the other hand, influence sugar price levels and an increase in their volatility levels also impacts, though less strongly, on sugar markets.

 Lura National Park (41°43.039 ʹ N, 20°11.908 ʹ E, 1430 m a.s.l.), 28 June 2011, 1 sexually active ♂ ad. netted over a road in an old mountain beech forest.
 This record fills the large gap in the distribution of this rarely recorded species in the western Balkans, where it was previously recorded only in Croatia (Kovač et al. 2011) and Greece (Hanák et al. 2001). As N. lasiopterus depends strongly on old hollow trees for roosting (Estók et al. 2007), it may be restricted to difficult-to-access mountain locations in Albania due to the heavy deforestation of lowland areas (Habili et al. 1997).

description: We propose an extension of the evolutionary Prisoner's Dilemma cellular automata, introduced by Nowak and May \cite{nm92}, in which the pressure of the environment is taken into account. This is implemented by requiring that individuals need to collect a minimum score $U_{min}$, representing indispensable resources (nutrients, energy, money, etc.) to prosper in this environment. So the agents, instead of evolving just by adopting the behaviour of the most successful neighbour (who got $U^{msn}$), also take into account if $U^{msn}$ is above or below the threshold $U_{min}$. If $U^{msn}

description: We investigate the stability regions of hypothetical terrestrial planets around the Lagrangian equilibrium points L4 and L5 in some specific extrasolar planetary systems. The problem of their stability can be treated in the framework of the restricted three body problem where the host star and a massive Jupiter-like planet are the primary bodies and the terrestrial planet is regarded as being massless. From these theoretical investigations one cannot determine the extension of the stable zones around the equilibrium points. Using numerical experiments we determined their largeness for three test systems chosen from the table of the know extrasolar planets, where a giant planet is moving close to the so-called habitable zone around the host star in low eccentric orbits. The results show the dependence of the size and structure of this region, which shrinks significantly with the eccentricity of the known gas giant.

description: This paper examines the relationship between calving date and production costs on Irish dairy farms from 2000-2007. Using data from the National Farm Survey, the median calving dates of 400 dairy farms are studied each year using econometric analysis to determine the relationship between calving date and production costs. Farms are divided into five categories according to their median calving date. These categories are imputed into a panel dataset as dummy variables. Unobservable individual effects are controlled for using a fixed effect model; examples of such effects are land quality and managerial ability, Results suggest that when scale and those unobserved effects are controlled for, there was no significant difference in total cost of production per litre according to median calving date

 Gomsiqe e Epërme (location same as above), 6 August 2003, 1 non-lactating ♀ ad. netted over a river in a rocky gorge. Syri i Kalter I (39°55.440 ʹ N, 20°11.564 ʹ E, 175 m a.s.l.), 23 April 2004, time-expanded echolocation calls of commuting individuals recorded over a karstic spring surrounded by a riparian woodland with oriental plane. The frequency of maximum energy was 43.2–44.5 (mean 44.2, n = 7), and the probability of correct species identification by iBatsID software was 0.93–0.99 (mean 0.97).
 Due to the separation of P. pipistrellus and P. pygmaeus (Barratt et al. 1997; Dietz et al. 2009) and the lack of any characters allowing for species identification, the only previous record (Uhrin et al. 1996) has to be assigned to P. pipistrellus sensu lato (Sachanowicz et al. 2006).
 Although scarcely known until 2003 (21 species and unidentified representatives of three species complexes), the bat fauna of Albania is presently adequately surveyed with 32 recorded species. Our research has confirmed that Albania is one of the European countries with the highest bat species richness. In the geographic Balkans, where 35 bat species are known (Dietz and Kiefer 2014), a greater or equal number of species has only been recorded in Bulgaria with 33 species if an acoustic record of Myotis dasycneme (Boie, 1825) over the Danube river is included (Benda et al. 2003; Mayer et al. 2007; Niermann et al. 2007) and continental Greece with 32 species (Hanák et al. 2001; Mayer et al. 2007). For two of the rarest European bats, R. mehelyi and N. lasiopterus, but also for M. brandtii, Pl. kolombatovici and B. barbastellus, we greatly extended their known geographic ranges in the south of Europe (Dietz et al. 2009). The previous record of M. nattereri in Albania (Chytil and Vlašín 1994) was most probably of this species, which is the only representative of the M. nattereri complex confirmed in the Balkans so far (Salicini et al. 2013). Of the two Balkan species not recorded in Albania, Eptesicus nilssonii is only known from single localities in Bulgaria (Benda et al. 2003) and Croatia (Pavlinić and Tvrtković 2003) whereas the known range of M. aurascens (sensu Mayer et al. 2007) covers only a small area of northeast Bulgaria and extends to Romania, Ukraine and Russia (Dietz and Kiefer 2014).

description: We explore the possibility of inducing in heterostructures driven by an ac gate voltage the coherent current suppression recently found for nanoscale conductors in oscillating fields. The destruction of current is fairly independent of the transport voltage, but can be controlled by the driving amplitude and frequency. Within a tight-binding approximation, we obtain analytical results for the average current in the presence of driving. These results are compared against an exact numerical treatment based on a transfer-matrix approach.
