description: Estimation and prediction risk are shown to influence the optimal storage decision of a dominant firm facing a competitive fringe. The presence of risk with respect to demand estimation and supply prediction results in increased storage by a dominant firm exercising market power in a two period profit maximization scenario. Bayesian numerical integration is employed to derive the optimal storage decision for a hypothetical cooperative of Georgia pecan growers facing demand estimation risk, supply prediction risk and a combination of the two.

description: An exact solution of a Landau model of an order-disorder transition with activated critical dynamics is presented. The model describes a funnel-shaped topography of the order parameter space in which the number of energy lowering trajectories rapidly diminishes as the ordered ground-state is approached. This leads to an asymmetry in the effective transition rates which results in a non-exponential relaxation of the order-parameter fluctuations and a Vogel-Fulcher-Tammann divergence of the relaxation times, typical of a glass transition. We argue that the Landau model provides a general framework for studying glassy dynamics in a variety of systems.

Gauge Problem in the Gravitational Self-Force II. First Post Newtonian Force under Regge-Wheeler Gauge

description: We discuss the gravitational self-force on a particle in a black hole space-time. For a point particle, the full (bare) self-force diverges. It is known that the metric perturbation induced by a particle can be divided into two parts, the direct part (or the S part) and the tail part (or the R part), in the harmonic gauge, and the regularized self-force is derived from the R part which is regular and satisfies the source-free perturbed Einstein equations. In this paper, we consider a gauge transformation from the harmonic gauge to the Regge-Wheeler gauge in which the full metric perturbation can be calculated, and present a method to derive the regularized self-force for a particle in circular orbit around a Schwarzschild black hole in the Regge-Wheeler gauge. As a first application of this method, we then calculate the self-force to first post-Newtonian order. We find the correction to the total mass of the system due to the presence of the particle is correctly reproduced in the force at the Newtonian order.

Year: 2012
Subjects: Crop Production/Industries

description: This paper looks at the experiences of agricultural input retailers in Malawi as a result of the Agricultural Input Subsidy Program. In particular, it focuses on the impact of excluding private sector retailers from participation in the subsidy program. Using a difference-in-difference approach to modeling fertilizer sales, it attempts to evaluate how retailers who were allowed to participate for part of the duration of the program but were then excluded experienced this policy change in comparison to retailers who were not allowed to participate at any point in the program. Furthermore, by looking at survey attrition over a two-year period, this paper looks at the evidence for and against the case that the subsidy program is driving private sector retailers out of business entirely. Due to known problems with the data and the results of testing done in the process of this research, this paper goes on to discuss the ideal methods that could produce the data needed to more accurately and comprehensively address the questions discussed in the first parts of the paper.

description: The media are under increasing pressure by states to adopt a regime-friendly editorial line in many countries globally, raising the importance of understanding the conditions of successful and failed media capture. Unfortunately, the standard measurement of media capture – annual expert surveys – neither distinguishes between outlets nor offers the needed resolution to assess, e.g., the immediate impact of a new gag law. To remedy these shortcomings, we develop a computational measurement of media capture based on a comparison of nominally independent outlets and regime-owned outlets regarding media agenda and tone when referring to the regime. By relying on two unsupervised measurement methods – topic modelling and sentiment classification – the new method can assess the loss of editorial independence at the level of individual outlets on a monthly or even weekly basis. The methodology is validated by applying it to recent data from Nicaragua. There the two-pronged approach shows how outlets respond differently to regime pressure. While there still are limitations to consider, if further editorial aspects of media capture such as issue framing are added to the methodology, it has the potential of transforming the future study of media capture.

description: It is commonly anticipated that an insulating state collapses in favor of an emergent metallic state at high pressures as the unit cell shrinks and the electronic bandwidth broadens to fill the insulating energy band gap. Here we report a rare insulating state that persists up to at least 185 GPa in the antiferromagnetic iridate Sr2IrO4, which is the archetypical spin-orbit-driven Jeff = 1/2 insulator. This study shows the electrical resistance of single-crystal Sr2IrO4 initially decreases with applied pressure, reaches a minimum in the range, 32 - 38 GPa, then abruptly rises to fully recover the insulating state with further pressure increases up to 185 GPa. Our synchrotron x-ray diffraction and Raman scattering data show the onset of the rapid increase in resistance is accompanied by a structural phase transition from the native tetragonal I41/acd phase to an orthorhombic Pbca phase (with much reduced symmetry) at 40.6 GPa. The clear-cut correspondence of these two anomalies is key to understanding the stability of the insulating state at megabar pressures: Pressure-induced, severe structural distortions prevent the expected metallization, despite the 26% volume compression attained at the highest pressure accessed in this study. Moreover, the resistance of Sr2IrO4 remains stable while the applied pressure is tripled from 61 GPa to 185 GPa. These results suggest that a novel type of electronic Coulomb correlation compensates the anticipated band broadening in strongly spin-orbit-coupled materials at megabar pressures.

description: Previous research on delegative democracy has predominantly emphasized its structural aspects, leaving the individual-level determinants of support for this governance relatively unexplored. While some studies have investigated the association between trust in the president and delegative democratic attitudes (DDA), the connection between technocratic beliefs, DDA, and the context of national emergencies has been minimally addressed. This study aims to fill this research gap by examining the correlation between technocratic beliefs and DDA, specifically focusing on how emergencies influence this relationship. Analysing data from the Asian Barometer Survey and the World Values Survey, the results indicate a robust connection between individuals’ technocratic beliefs and DDA. Moreover, this correlation exhibits greater strength as a country’s level of emergency escalates. These results may provide valuable insights into our understanding of both individual and structural factors associated with public support for delegative democracy.
Vortex states in 2D superconductor at high magnetic field in a periodic pinning potential

description: The effect of a periodic pinning array on the vortex state in a 2D superconductor at low temperatures is studied within the framework of the Ginzburg-Landau approach. It is shown that attractive interaction of vortex cores to a commensurate pin lattice stabilizes vortex solid phases with long range positional order against violent shear fluctuations. Exploiting a simple analytical method, based on the Landau orbitals description, we derive a rather detailed picture of the low temperatures vortex state phase diagram. It is predicted that for sufficiently clean samples application of an artificial periodic pinning array would enable one to directly detect the intrinsic shear stiffness anisotropy characterizing the ideal vortex lattice.

description: Some aspects of lasing at vibronic transitions in impurity crystals are theoretically studied. The threshold conditions for a vibronic laser are shown to be dependent on the strength of interaction of optical centers with a local vibration, which forms the vibronic spectrum, and the crystal lattice temperature. The theory can be easily generalized to the spectrum containing a structureless phonon sideband and well agrees with the experimental temperature dependence of the output power of a Mg2SiO4:Cr4+ forsterite laser.

description: We investigate a class of Cardassian scenarios of the universe evolution in notions of the qualitative theory of dynamical systems. This theory allows us to analyze all solutions for all possible initial conditions on the phase plane. In the Cardassian models we find that big-rip singularities are present as a typical behavior in the future if $n<0$. Some exact solutions for the flat Cardassian models as well as a duality relation were found. In turn from the statistical analysis of Knop's SNIa data, without any priors on matter content in the model, we obtain that at the 99% confidence level this big-rip scenario will reach. The potential function for the Hamiltonian description of dynamics is reconstructed from the SNIa data (inverse dynamical problem). We also pointed out the statistical analysis results depend oversensitively on the choice of the model parameter $\mathcal{M}$.

description: We present the ensemble expectation values for the translation invariant, rank-2 Minkowski tensors in three-dimensions, for a linearly redshift space distorted Gaussian random field. The Minkowski tensors $W^{0,2}_{1}$, $W^{0,2}_{2}$ are sensitive to global anisotropic signals present within a field, and by extracting these statistics from the low redshift matter density one can place constraints on the redshift space distortion parameter $β= f/b$. We begin by reviewing the calculation of the ensemble expectation values $\langle W^{0,2}_{1} \rangle$, $\langle W^{0,2}_{2} \rangle $ for isotropic, Gaussian random fields, then consider how these results are modified by the presence of a linearly anisotropic signal. Under the assumption that all fields remain Gaussian, we calculate the anisotropic correction due to redshift space distortion in a coordinate system aligned with the line of sight, finding inequality between the diagonal elements of $\langle W^{0,2}_{1} \rangle $, $\langle W^{0,2}_{2} \rangle $. The ratio of diagonal elements of these matrices provides a set of statistics that are sensitive only to the redshift space distortion parameter $β$. We estimate the Fisher information that can be extracted from the Minkowski tensors, and find $W^{0,2}_{1}$ is more sensitive to $β$ than $W^{0,2}_{2}$, and a measurement of $W^{0,2}_{1}$ accurate to $\sim 1\%$ can yield a $\sim 4\%$ constraint on $β$. Finally, we discuss the difference between using the matrix elements of the Minkowski tensors directly against measuring the eigenvalues. For the purposes of cosmological parameter estimation we advocate the use of the matrix elements, to avoid spurious anisotropic signals that can be generated by the eigenvalue decomposition.

description: We present an algorithm which is designed to allow the efficient identification and preliminary dynamical analysis of thousands of structures and substructures in large N-body simulations. First we utilise a refined density gradient system (based on DENMAX) to identify the structures, and then apply an iterative approximate method to identify unbound particles, allowing fast calculation of bound substructures. After producing a catalog of separate energetically bound substructures we check to see which of these are energetically bound to adjacent substructures. For such bound complex subhalos, we combine components and check if additional free particles are also bound to the union, repeating the process iteratively until no further changes are found. Thus our subhalos can contain more than one density maximum, but the scheme is stable: starting with a small smoothing length initially produces small structures which must be combined later, and starting with a large smoothing length produces large structures within which sub-substructure is found. We apply this algorithm to three simulations. Two which are using the TPM algorithm by Bode et al. (2000) and one on a simulated halo by Diemand (2004). For all these halos we find about 5-8% of the mass in substructures.

description: Bis(dibenzyldithiocarbamato)Zn(II), [Zn(dbzdtc)2], was synthesized and characterized by spectroscopic techniques, elemental analysis and single crystal X-ray crystallography. The compound is crystallized in a monoclinic space group P21/n with Zn(II) located on crystallographic twofold symmetry and coordinated to two molecules of dibenzyl dithiocarbamato anions to form a rare four-coordinate mononuclear Zn(II) complex in a see-saw geometry. The cytotoxicity of the complex was evaluated by MTT assay against breast cancer cells (MCF-7) and human embryonic kidney cells (HEK293). The results showed that the complex is active against MCF-7 breast cancer cells with IC50 value of 6.41 and 4.423 μΜ against HEK293 cell line.

description: Predatory journals are Open Access journals of highly questionable scientific quality. Such journals pretend to use peer review for quality assurance, and spam academics with requests for submissions, in order to collect author payments. In recent years predatory journals have received a lot of negative media. While much has been said about the harm that such journals cause to academic publishing in general, an overlooked aspect is how much articles in such journals are actually read and in particular cited, that is if they have any significant impact on the research in their fields. Other studies have already demonstrated that only some of the articles in predatory journals contain faulty and directly harmful results, while a lot of the articles present mediocre and poorly reported studies. We studied citation statistics over a five-year period in Google Scholar for 250 random articles published in such journals in 2014, and found an average of 2,6 citations per article and that 60 % of the articles had no citations at all. For comparison a random sample of articles published in the approximately 25,000 peer reviewed journals included in the Scopus index had an average of 18,1 citations in the same period with only 9 % receiving no citations. We conclude that articles published in predatory journals have little scientific impact.

Com destaque para os ganhos médios de produtividade que foram cerca de duas vezes superior aos da média nacional. Dessa maneira, o objetivo deste trabalho foi mensurar a produtividade total dos fatores (PTF) no cultivo de algodão, arroz, feijão, milho e soja, para o estado de São Paulo, no período de 1985 a 2001. Especificamente, pretendeu-se verificar se os ganhos de produtividade das culturas selecionadas são advindos de ganhos de eficiência e, ou, de mudança tecnológica e se esses ganhos são maiores para o período posterior à abertura da economia brasileira. Para isso, utilizaram-se os modelos de Análise Envoltória de Dados (DEA). Os resultados apontaram para ganhos tanto de eficiência técnica quanto de mudança tecnológica. Ademais, para períodos posteriores à abertura da economia brasileira foram constatados maiores indicadores de mudanças tecnológicas, principalmente para culturas de exportação. Assim, foi possível concluir que a abertura comercial influenciou positivamente a PTF na agricultura do estado de São Paulo. -----------------------------------------------------In agriculture Paulo were recorded in some years of the 1990s, significant productivity gains.

Specifically, we sought to verify whether the gains in crop productivity Featured are coming from efficiency gains and, or, technological change and if these gains are higher for the period following the opening of the Brazilian economy. For this, used the models Data envelopment analysis (DEA). The results showed gains for both technical efficiency as technological change. Further, for periods after the opening of the Brazilian economy was verified larger indicators technological changes, particularly for export crops. Thus it was possible conclude that trade liberalization had a positive influence on agricultural TFP State São Paulo.

description: Hierarchical linker thermolysis has been used to enhance the porosity of monolithic UiO-66-based metal-organic frameworks (MOFs) containing 30 wt% 2-aminoterephthalic acid (BDC-NH2) linker. In this multivariate (i.e. mixed-linker) MOF, the thermolabile BDC-NH2 linker decomposed at ∼350 °C, inducing mesopore formation. The nitrogen sorption of these monolithic MOFs was probed, and an increase in gas uptake of more than 200 cm3 g−1 was observed after activation by heating, together with an increase in pore volume and mean pore width, indicating the creation of mesopores. Water sorption studies were conducted on these monoliths to explore their performance in that context. Before heating, monoUiO-66-NH2-30%-B showed maximum water vapour uptake of 61.0 wt%, which exceeded that reported for either parent monolith, while the highly mesoporous monolith (monoUiO-66-NH2-30%-A) had a lower maximum water vapour uptake of 36.2 wt%. This work extends the idea of hierarchical linker thermolysis, which has been applied to powder MOFs, to monolithic MOFs for the first time and supports the theory that it can enhance pore sizes in these materials. It also demonstrates the importance of hydrophilic functional groups (in this case, NH2) for improving water uptake in materials.

description: The newly discovered superconductivity in MgCNi3, though with Tc<8 K lower than that of the celebrated MgB2, is probably even more interesting in its many puzzling physical properties. MgCNi3 has been theoretically speculated to be unstable towards ferromagnetism. However, there are numerous evidences from the specific heat C(T), Tunneling spectroscopy and NMR experiments indicating conventional s-wave superconductivity in MgCNi3. The Hall effect and the thermoelectric power experiments suggest that the carriers responsible for the transport properties are electrons, in obvious contrast to holes predicated by the band structure calculations. In this article, we report the results of C(T) experiments, upper critical field Hc2 measurements, and the pressure effects on MgCNi3. These experimental evidences clearly demonstrate that superconductivity in MgCNi3 is well explained within the conventional electron-phonon interaction scenario, at most with minor modifications from the magnetic interaction. The thermodynamic data C(T) is consistent with the conventional s-wave order parameter. Hc2 of all samples follows a universal WHH relation . Surprisingly, dTc/dP is positive which leaves room for further improvements in band structure calculations. There are other serious discrepancies between experiments and theory like in the transport properties and x-ray photoemission. The possible reconciliation within the two-band model and the consequent difficulties are discussed.

description: Bodies concerned with conservation need funds to carry out their conservation activities. This requires them to communicate effectively with potential donors or lenders. Economic factors can influence choices in this regard. Most donors like to see value for money or resources used so it is important to present a 'prospectus' or case well in this respect. The prospectus for "Heritage Fund of the Bahamas National Trust (1992) provides an excellent example of a well presented case for financial support. Some economic guidelines for presenting arguments to donors (or lenders) in relation to value for money are presented. Risk in relation to funding and investment portfolios for protected areas is discussed and the role of economists in providing financial advice is outlined.

description: Primary adrenal insufficiency due to tumor involvement is very rare. We herein report a case of adrenal insufficiency caused by cancer metastasis to a remaining single adrenal gland in a renal cell carcinoma patient who had undergone radical nephrectomy including removal of the right adrenal gland. The patient presented with abdominal discomfort, nausea, and vomiting which had begun about 3 months earlier. A rapid adrenocorticotropic hormone (ACTH) test showed no cortisol response with upper normal level of baseline ACTH. The patient was treated with prednisolone after diagnosis of primary adrenal insufficiency due to adrenal metastasis. The symptoms improved after prednisolone replacement. The case reminds clinicians the diagnosis of primary adrenal insufficiency due to tumor metastasis should be considered in patients with nonspecific gastrointestinal symptoms.

description: This paper has the purpose of testing the expectations hypothesis of the term structure for two corporate bond yields. A new test is developed based on an ARIMA data generation process of the short rate, and on the derivation of a relation between the change in the long rate and revisions of expectations of future short rates. The paper makes the point that adjustment of the change in the long rate to short rate news does not occur instantaneously but is dynamic over time. For this reason a polynomial distributed lag of the rate news, which provides support to the expectations hypothesis, is estimated. This is quite remarkable because the liquidity, term, and default risk premiums are left out of the analysis.

title: New approaches to measuring economic and social well-being in Chile

description: I propose three new measures of social and economic well-being using different approaches. These measures are applied to Chile using two household surveys: the Panel CASEN and the Financial Survey. First, I use an income positions persistence approach to estimate the persistence of households in different positions of the income distribution. The application of this measure enables us to understand the mechanisms that explain why those at the lower end of the income distribution have a low probability of moving up (sticky floor), and those at the higher end of the income distribution have less chance of moving down (glass floor). The results show that income mobility is particularly high for all groups in the income distribution. Second, I use a low-income dynamic approach to estimate degrees of vulnerability to poverty. This measure enables us to obtain two vulnerability lines that measure the risk of non-poor households falling into poverty in the next period. This enables the identification of three types of households: those with high, moderate and low vulnerability. The latter corresponds to the income-secure middle class. The results show that vulnerability to poverty affects a significant part of the population that exited poverty in the last decade. Third, I use a multidimensional approach to measure economic insecurity at the household level. I build an index that combines four indicators of economic insecurity that cause stress and anxiety: unexpected economic shocks, unprotected employment, over-indebtedness and asset poverty. In this way, the index offers a measure that directly relates economic uncertainty to stress due to the lack of social protection and household buffers to face an unexpected economic shock. The results show that households in the entire income distribution

description: Our community has greatly improved the efficiency of deep learning applications, including by exploiting sparsity in inputs. Most of that work, though, is for inference, where weight sparsity is known statically, and/or for specialized hardware. We propose a scheme to leverage dynamic sparsity during training. In particular, we exploit zeros introduced by the ReLU activation function to both feature maps and their gradients. This is challenging because the sparsity degree is moderate and the locations of zeros change over time. We also rely purely on software. We identify zeros in a dense data representation without transforming the data and performs conventional vectorized computation. Variations of the scheme are applicable to all major components of training: forward propagation, backward propagation by inputs, and backward propagation by weights. Our method significantly outperforms a highly-optimized dense direct convolution on several popular deep neural networks. At realistic sparsity, we speed up the training of the non-initial convolutional layers in VGG16, ResNet-34, ResNet-50, and Fixup ResNet-50 by 2.19x, 1.37x, 1.31x, and 1.51x respectively on an Intel Skylake-X CPU.
Quasi-Periodic Oscillations from Low-Mass X-Ray Binaries with Neutron Stars

description: Before the launch of the Rossi X-ray Timing Explorer (RXTE) it was recognized that neutron star accretion disks could extend inward to very near the neutron star surface, and thus be governed by millisecond timescales. Previous missions lacked the sensitivity to detect them. The kilohertz quasi-periodic oscillations (QPO) that RXTE discovered are often, but not always, evident in the X-ray flux. In 8 years RXTE has found kilohertz signals in about a fourth of 100 low-mass X-ray binaries (LMXB) containing neutron stars. The observed power spectra have simple dominant features, the two kilohertz oscillations, a low frequency oscillation, and band-limited white noise. They vary systematically with changes in other source properties and offer the possibility of comparison with model predictions. New information from the millisecond pulsars resolves some questions about the relations of the QPO and the spin. Coherence, energy spectrum and time lag measurements have indicated systematic behaviors, which should constrain mechanisms.

description: For the past few decades, the household healthcare expenditures have experienced a phenomenal growth in Singapore. This paper seeks to identify the underlying socio-economic factors that contribute towards this phenomenon by employing time series data to examine the household willingness to spend on healthcare from 1970 to 2006. The results from our log-linear regression show that the willingness to spend on healthcare is positively related to the proportion of Singapore's population who are elderly, the literacy rate, the ratio of price of other goods and services to the price of healthcare, and the establishment of Singapore's mandatory health savings plan, Medisave. In terms of their effects on the growth of Singapore's willingness to spend on healthcare, the most important factors are the ageing of the population and the increase in the literacy rate.

description: We study the chemodynamical evolution of elliptical galaxies and their X-ray and optical properties using high-resolution cosmological simulations. Our Tree N-body/SPH code includes a self-consistent treatment of radiative cooling, star formation, supernovae feedback, and chemical enrichment. We present a series of LCDM cosmological simulations which trace the spatial and temporal evolution of abundances of heavy element in both the stellar and gas components of galaxies. A giant elliptical galaxy formed in the simulations is quantitatively compared with the observational data in both the X-ray and optical regime. X-ray spectra of the hot gas are constructed via the use of the vmekal plasma model, and analysed using XSPEC with the XMM EPN response function. Optical properties are derived by the population synthesis for the stellar component. We find that radiative cooling is important to interpret the observed X-ray luminosity, temperature, and metallicity of the hot gas of elliptical galaxies. However, this cooled gas also leads to excessive star formation at low redshift, and therefore results in underlying galactic stellar populations which are too blue with respect to observations. Time variation and radial dependence of X-ray properties and abundance ratios, such as [O/Fe] and [Si/Fe], of the X-ray emitting hot gas are also discussed.

description: When time-reversal symmetry is broken on its surface, topological insulators exhibit a magnetoelectric response which is described by axion electrodynamics. A direct consequence of this theory is the appearance of a magnetic field that resembles the one produced by a magnetic image monopole when a point-like electric charge is located near the surface of the material. In this paper we investigate the more realistic problem when the point-like charge is replaced by a finite size sphere at constant potential. We calculate the electromagnetic fields using the potential formulation in a particular bispherical coordinate system. We find that the electromagnetic fields can be interpreted in terms of point electric and image magnetic charges as if the medium were the vacuum. As a manifestation of the magnetoelectric effect, we highlight the resulting magnetic field, which we analyze in detail along the symmetry axis, since such estimates could be useful in evaluating the experimental possibility of its measurement via sensible magnetometers. Our numerical estimates show that the proposed setup provides a magnetic field strength in the range of 10-100 mG, which is attainable with present day sensitivities in NV center-diamond magnetometers, for example.
