description: The results of Hubble Space Telescope and UKIRT imaging observations are presented for a sample of 11 6C radio galaxies with redshifts 0.85 < z < 1.5. The observations of the 6C sources reveal a variety of different features, similar to those observed around the higher luminosity of the aligned emission appears less extreme in the case of the 6C radio galaxies. For both samples, the aligned emission clearly cannot be explained by a single emission mechanism; line emission and related nebular continuum emission, however, often provide a significant contribution to the aligned emission.

description: We evaluate the large-$N$ behavior of the superconformal indices of toric quiver gauge theories, and use it to find the entropy functions of the dual electrically charged rotating $\mathrm{AdS}_5$ black holes. To this end, we employ the recently proposed Bethe Ansatz method, and find a certain set of solutions to the Bethe Ansatz Equations of toric theories. This, in turn, allows us to compute the large-$N$ behavior of the index for these theories, including the infinite families $Y^{pq}$, $X^{pq}$ and $L^{pqr}$ of quiver gauge theories. Our results are in perfect agreement with the predictions made recently using the Cardy-like limit of the superconformal index. We also explore the index structure in the space of chemical potentials and describe the pattern of Stokes lines arising in the conifold theory case.

description: We investigate the motion of a tagged spin in a ferromagnetic Ising chain evolving under Kawasaki dynamics. At equilibrium, the displacement is Gaussian, with a variance growing as $A t^{1/2}$. The temperature dependence of the prefactor $A$ is derived exactly. At low temperature, where the static correlation length $ξ$ is large, the mean square displacement grows as $(t/ξ^2)^{2/3}$ in the coarsening regime, i.e., as a finite fraction of the mean square domain length. The case of totally asymmetric dynamics, where $(+)$ (resp. $(-)$) spins move only to the right (resp. to the left), is also considered. In the steady state, the displacement variance grows as $B t^{2/3}$. The temperature dependence of the prefactor $B$ is derived exactly, using the Kardar-Parisi-Zhang theory. At low temperature, the displacement variance grows as $t/ξ^2$ in the coarsening regime, again proportionally to the mean square domain length.

Photometry and the Metallicity Distribution of the Outer Halo of M31. II. The 30 Kpc Field

description: We present the results of a wide-field (V,I) photometric study of the red-giant branch (RGB) stars in the outer halo of M31, in a field located 30 to 35 kpc from the center of the galaxy along the southeast minor axis. At this remote location, we find that RGB stars belonging to M31 are sparsely but definitely present, after statistical subtraction of field contamination. We derive the metallicity distribution (MDF) for the halo stars using interpolation within a standard (I,V-I) grid of RGB evolutionary tracks. The halo MDF is quite broad but dominated by a moderately high-metallicity population peaking at [m/H] ~ -0.5, strikingly different from the [m/H] ~ -1.3 level which characterizes the outer halo of the Milky Way. However,the shape and peak metallicity for this region are entirely similar to those found in other studies for the inner regions of the M31 halo, particularly our previous study of a 20-kpc region (Durrell, Harris, & Pritchet 2001) employing similar data. In summary, we find no evidence for a metallicity gradient or systematic change in the MDF out to quite large distances in the M31 halo: it appears to be a homogeneous and moderately metal-rich subsystem of the galaxy at all locations. The star counts in the 30-kpc field are also consistent with the r^1/4 law that fits the interior regions of the M31 spheroid surface brightness profile. The metal-rich MDF and the r^1/4 spheroid suggests M31 more strongly resembles a giant elliptical galaxy than other, Milky-Way-like, spirals.

description: We investigate pattern revivals in specially designed optical structures that combine different transverse modes. In general, the resulting pattern is not preserved under free propagation and gets transformed due to non synchronized Gouy phases. However, it is possible to build structures in which the Gouy phases synchronize at specific fractional values, thus recovering the initial pattern at the corresponding longitudinal positions. This effect is illustrated with a radially structured light spot in which the beam energy can be addressed to different positions without the need of intermediate optical components, what can be useful for optical communications and optical tweezing with structured beams.

description: Continuous submodular functions are a category of generally non-convex/non-concave functions with a wide spectrum of applications. The celebrated property of this class of functions - continuous submodularity - enables both exact minimization and approximate maximization in poly. time. Continuous submodularity is obtained by generalizing the notion of submodularity from discrete domains to continuous domains. It intuitively captures a repulsive effect amongst different dimensions of the defined multivariate function.
In this paper, we systematically study continuous submodularity and a class of non-convex optimization problems: continuous submodular function maximization. We start by a thorough characterization of the class of continuous submodular functions, and show that continuous submodularity is equivalent to a weak version of the diminishing returns (DR) property. Thus we also derive a subclass of continuous submodular functions, termed continuous DR-submodular functions, which enjoys the full DR property. Then we present operations that preserve continuous (DR-)submodularity, thus yielding general rules for composing new submodular functions. We establish intriguing properties for the problem of constrained DR-submodular maximization, such as the local-global relation. We identify several applications of continuous submodular optimization, ranging from influence maximization, MAP inference for DPPs to provable mean field inference. For these applications, continuous submodularity formalizes valuable domain knowledge relevant for optimizing this class of objectives. We present inapproximability results and provable algorithms for two problem settings: constrained monotone DR-submodular maximization and constrained non-monotone DR-submodular maximization. Finally, we extensively evaluate the effectiveness of the proposed algorithms.

description: Glipizide is known to stimulate insulin secretion by β-cells of the pancreas. It is a second-generation sulfonylurea drug used in the management of type 2 diabetes. The shorter biological half-life makes it a suitable candidate to be designed as a controlled release formulation. Human serum albumin (HSA), a major plasma protein plays a crucial role in the transportation of drugs, hormones, fatty acids, and many other molecules and determines their physiological fate and biodistribution. In this study, the interaction of glipizide with HSA was investigated under physiological conditions using multi-spectroscopic techniques corroborated with molecular docking and dynamics approach. It was found that glipizide integrates to HSA with a binding constant in the order of 105 M-1. The mode of fluorescence quenching by glipizide is static in nature with one binding site. Glipizide preferentially interacts with sub-domain IIA of HSA and their complexion is thermodynamically favorable. This interaction results in the loss of α-helical content of HSA. The energy transfer efficiency from HSA to glipizide was found to be 26.72%. In silico molecular docking and simulation studies ratified in vitro findings and revealed that hydrogen bonds and hydrophobic interactions are accountable for glipizide-HSA complex formation.

description: We formulate the quark meson coupling model as a many-body effective Hamiltonian. This leads naturally to the appearance of many-body forces. We investigate the zero range limit of the model and compare its Hartree-Fock Hamiltonian to that corresponding to the Skyrme effective force. By fixing the three parameters of the model to reproduce the binding and symmetry energy of nuclear matter, we find that it allows a very satisfactory interpretation of the Skyrme force.

description: O objetivo deste trabalho foi obter, através do uso da programação linear, sistemas de produção agrícola capazes de otimizar os recursos de agricultores familiares das regiões Norte e Noroeste Fluminense, e proporcionar-lhes aumento de renda. Foram estudados alguns casos de agricultores pertencentes aos grupos A, C e D do Pronaf, dos quais foram obtidas as informações sobre dotação dos recursos, bem como sobre custos e margens brutas, necessárias à programação. Numa primeira análise, em que os riscos foram desconsiderados, o cultivo da goiaba destacou-se como a melhor opção para otimização dos recursos e geração de renda. Quando foram considerados os riscos de redução das margens brutas, decorrentes de queda nos preços dos produtos, planos ótimos alternativos foram obtidos. Constatou-se que, com a opção por sistemas de produção envolvendo o cultivo simultâneo de maracujá e goiaba, principalmente, haveria redução dos riscos, sem grave comprometimento da renda gerada. Constatou-se, ainda, que os recursos de custeio do Pronaf contribuíram para elevar o uso da terra, aumentar o retorno das atividades e para a contratação de trabalhadores adicionais, principalmente em se tratando de agricultores pertencentes aos grupos A e D.

description: We study a spin S=M/2--Kondo system coupled to electrons in an arbitrary nonequilibrium situation above Kondo temperature. Coupling to hot electrons leads to an increased inverse lifetime of pseudo particles, related to the Korringa width. This in turn is responsible for the increased inelastic relaxation rates of the electronic system. The rates are related to spin--spin correlation functions which are determined using a projection operator formalism. The results generalize recent findings for S=1/2--Kondo impurities which have been used to describe energy relaxation experiments in disordered mesoscopic wires.

description: This paper introduces a method of calculating and rendering shapes in a non-Euclidean 2D space. In order to achieve this, we developed a physics and graphics engine that uses hyperbolic trigonometry to calculate and subsequently render the shapes in a 2D space of constant negative or positive curvature in real-time. We have chosen to use polar coordinates to record the parameters of the objects as well as an azimuthal equidistant projection to render the space onto the screen because of the multiple useful properties they have. For example, polar coordinate system works well with trigonometric calculations, due to the distance from the reference point (analogous to origin in Cartesian coordinates) being one of the coordinates by definition. Azimuthal equidistant projection is not a typical projection, used for neither spherical nor hyperbolic space, however one of the main features of our engine relies on it: changing the curvature of the world in real-time without stopping the execution of the application in order to re-calculate the world. This is due to the projection properties that work identically for both spherical and hyperbolic space, as can be seen in the Figure 1 above. We will also be looking at the complexity analysis of this method as well as renderings that the engine produces. Finally we will be discussing the limitations and possible applications of the created engine as well as potential improvements of the described method.

description: Using a cellular automata model, we simulate the British Government Policy (BGP) in the 2001 foot and mouth epidemic in Great Britain. When clinical symptoms of the disease appeared on a farm, there is mandatory slaughter (culling) of all livestock on an infected premise (IP). Those farms that neighbor an IP (contiguous premise, CP), are also culled, aka nearest neighbor interaction. Farms where the disease may be prevalent from animal, human, vehicle or airborne transmission (dangerous contact, DC), are additionally culled, aka next-to-nearest neighbor iteractions and lightning factor. The resulting mathematical model possesses a phase transition, whereupon if the physical disease transmission kernel exceeds a critical value, catastrophic loss of animals ensues. The non-local disease transport probability can be as low as .01% per day and the disease can still be in the high mortality phase. We show that the fundamental equation for sustainable disease transport is the criticality equation for neutron fission cascade. Finally, we calculate that the percentage of culled animals that are actually healthy is ~ 30%.

description: A partir da última década do século XX a floricultura no Nordeste Brasileiro tem apresentando acentuado desenvolvimento, passando a repercutir nas ações do Banco do Nordeste do Brasil (BNB), que já conta com vários projetos financiados para produção e pesquisa tecnológica. Como principal órgão de desenvolvimento e de crédito do Nordeste, tornou-se necessário conhecer as características e os problemas da floricultura na Região, de forma a contribuir para o seu crescimento equilibrado. O objetivo geral desta pesquisa foi subsidiar a política do BNB e de outras agências de desenvolvimento para a atividade, caracterizando-a, de modo a possibilitar a geração de planos de ação a partir das sugestões contidas no estudo elaborado. As fontes de informações para a realização do trabalho foram entrevistas com técnicos de instituições públicas, produtores, varejistas, fornecedores de insumos, revisão bibliográfica da literatura especializada, páginas da Internet; além da aplicação de 2 tipos diferentes de questionários com questões abertas aplicados aos produtores e varejistas. Os resultados da pesquisa permitem concluir que a Região apresenta grande potencial para o desenvolvimento da atividade, mas existem ainda muitas barreiras que precisam ser eliminadas: Pequena oferta de insumos nas áreas produtoras, com reflexos na elevação dos custos de produção; Embora exista mão-de-obra abundante na Região, são pouco qualificadas; Grande quantidade de produtores informais atuando na Região, desorganizando o mercado; Produtores com pouca profissionalização e especialização; Concorrência dos produtos de outras regiões; Pequena dimensão do mercado regional, com grande disputa pela demanda; Baixo nível organizacional e associativo do produtor; Carência de técnicos com conhecimentos especializados; Poucas pesquisas sobre as espécies produzidas e estudos de mercado.

description: In this paper we propose a heterogeneous modeling framework which achieves individual-wise feature selection and heterogeneous covariates’ effects subgrouping simultaneously. In contrast to conventional model selection approaches, the new approach constructs a separation penalty with multi-directional shrinkages, which facilitates individualized modeling to distinguish strong signals from noisy ones and selects different relevant variables for different individuals. Meanwhile, the proposed model identifies subgroups among which individuals share similar covariates’ effects, and thus improves individualized estimation efficiency and feature selection accuracy. Moreover, the proposed model also incorporates within-individual correlation for longitudinal data to gain extra efficiency. We provide a general theoretical foundation under a double-divergence modeling framework where the number of individuals and the number of individual-wise measurements can both diverge, which enables inference on both an individual level and a population level. In particular, we establish a strong oracle property for the individualized estimator to ensure its optimal large sample property under various conditions. An efficient ADMM algorithm is developed for computational scalability. Simulation studies and applications to post-trauma mental disorder analysis with genetic variation and an HIV longitudinal treatment study are illustrated to compare the new approach to existing methods.

New Country Record. New Host Records.
 Cephaloleia consanguinea was previously known only from Guatemala, Costa Rica, and Panama (Staines 1996). Thus, these collections are new country records and extensions of the known range to include Belize. In the focus area for field work in southern Belize, four species of Heliconia occur (H. bourgaeana, H. collinsiana, H. latispatha, and H. wagneriana). Adults of C. consanguinea were common in the rolled, expanding leaves of all four species.
 Previously reported host plants for C. consanguinea are Heliconia imbricata (Kuntze) Baker, H. latispatha, H. mariae Hook., H. pogonantha Cuford, and H. tortuosa Griggs (Strong 1977). Staines (2004) mentioned that examination of Strong’s voucher specimens showed that the species studied was C. belti Baly rather than C. consanguinea. The collections cited are the first definitive hosts for C. consanguinea: H. bourgaeana, H. collinsiana, H. latispatha, and H. wagneriana. Given the collection of the beetle species from all locally available Heliconia species in Belize, C. consanguinea appears to be relatively general in its feeding preferences within the plant genus.

description: Multiple systems estimation strategies have recently been applied to quantify hard-to-reach populations, particularly when estimating the number of victims of human trafficking and modern slavery. In such contexts, it is not uncommon to see sparse or even no overlap between some of the lists on which the estimates are based. These create difficulties in model fitting and selection, and we develop inference procedures to address these challenges. The approach is based on Poisson log-linear regression modeling. Issues investigated in detail include taking proper account of data sparsity in the estimation procedure, as well as the existence and identifiability of maximum likelihood estimates. A stepwise method for choosing the most suitable parameters is developed, together with a bootstrap approach to finding confidence intervals for the total population size. We apply the strategy to two empirical datasets of trafficking in US regions, and find that the approach results in stable, reasonable estimates. An accompanying R software implementation has been made publicly available. Supplementary materials for this article are available online.

description: In this paper we present the V and I luminosity functions and color-magnitude diagrams derived from wide-field (23 arcmin by 23 arcmin) BVI photometry of the intermediate metallicity ([Fe/H]=-1.3) Galactic globular cluster M12. Using observed values (and ranges of values) for the cluster metallicity, reddening, distance modulus, and age we compare these data to recent alpha-enhanced stellar evolution models for low mass metal-poor stars. We describe several methods of making comparisons between theoretical and observed luminosity functions in order to isolate the evolutionary timescale information the luminosity functions contain. We find no significant evidence of excesses of stars on the red giant branch, although the morphology of the subgiant branch in the observed luminosity function does not match theoretical predictions in a satisfactory way. Current uncertainties in Teff-color transformations (and possibly also in other physics inputs to the models) make more detailed conclusions about the subgiant branch morphology impossible. Given the recent constraints on cluster ages from the WMAP experiment (Spergel et al. 2003), we find that good fitting models that do not include He diffusion (both color-magnitude diagrams and luminosity functions) are too old (by approximately 1-2 Gyr) to adequately represent the cluster luminosity function. The inclusion of helium diffusion in the models provides an age reduction (compared to non-diffusive models) that is consistent with the age of the universe being 13.7+/-0.2 Gyr (Bennett et al. 2003).

All of these states have adopted more specialized field staff because specialization is a key for increased productivity. In this paper, the term “field specialists” will be used for all specialized Extension Educator positions that are: 1) located in the field and not on campus, 2) focus their work within an area of expertise, 3) work either throughout the state or in large multi-county regions and 4) are funded primarily from state and federal funds and/or grants rather than funded partially by counties. Many of the field specialists have very similar backgrounds and responsibilities as the M.S. level state specialists of the 1980s and 1990s.

description: Xanthocomus Guillebeau, 1893
 Xanthocomus Guillebeau 1893: 291. Type species: Xanthocomus striatus Guillebeau, 1893.
 Leptostilbus Casey 1916: 71. Type species: Leptostilbus rutilans Casey, 1916, here designated. New synonymy.
 Diagnosis. Recognized among North American phalacrids by the mandible having a ventral fold; ventral seta-lined ridge behind eye oblique (not transverse); prosternal process with apex arcuate and with row of stiff setae; metaventral postcoxal lines smoothly arcuate; posterior tarsi with tarsomere I short, tarsomere II much longer than I; presence of rows of rounded (not crescentiform) punctures on the elytra; the elongate body form (pronotum more than half as long as wide); reddish coloration; and microsculpture very weak or absent over most of the elytral disc.
 Notes. With the addition of species from Leptostilbus, the genus Xanthocomus contains nine described species collectively distributed from the northern United States south to Argentina. They are also widespread in the West Indies. After examining the types of X. striatus (Muséum National d’Histoire Naturelle, Paris), the type species of Xanthocomus, and those of several other species, I have concluded that these genera should be combined. All species share the diagnostic characters presented above with the exception of the species described as Stilbus elongatulus Casey (1890: 136). Casey (1916: 73) subsequently transferred this species to Leptostilbus based on the structure of the hind tarsi, but neglected to observe the state of the metaventral postcoxal lines, which are distinctly acuminate posteriorly in this species. Additionally, the elytra are microsculptured with dense transverse lines. It actually belongs in the genus Acylomus Sharp, as Acylomus elongatulus (Casey, 1890), comb. nov. Neither Casey nor any more recent workers have designated a type species for Leptostilbus, so I have rectified this situation.

description: We study the zero-temperature Ising chain evolving according to the Swendsen-Wang dynamics. We determine analytically the domain length distribution and various ``historical'' characteristics, e.g., the density of unreacted domains is shown to scale with the average domain length as ^{-d} with d=3/2 (for the q-state Potts model, d=1+1/q). We also compute the domain length distribution for the Ising chain endowed with the zero-temperature Wolff dynamics.

description: This paper is concerned with improving the empirical convergence speed of block-coordinate descent algorithms for approximate nonnegative tensor factorization (NTF). We propose an extrapolation strategy in-between block updates, referred to as heuristic extrapolation with restarts (HER). HER significantly accelerates the empirical convergence speed of most existing block-coordinate algorithms for dense NTF, in particular for challenging computational scenarios, while requiring a negligible additional computational budget.

Modelling Viral Reassortment in Structured Populations

structured coalescent
reassortment

description: Migration dynamics of viral sub-populations are usually analysed by applying the
structured coalescent theory to genetic sequence data. This is, however, not trivial
for reassorting viruses that have segmented genomes. Recently, a coalescent
with reassortment approach was developed, allowing to use the full segmented
genome for phylodynamic analysis. We combine the two techniques into the
structured coalescent with reassortment model for exact and approximate inference.
We show that this method can accurately estimate sub-population dependent
effective populations sizes, reassortment and migration rates. Additionally,
we apply the new model on a seasonal influenza A/H3N2 dataset with 150 genomic
sequences for four viral segments, sampled at three distinct locations. We
contrast our results with a structured coalescent without reassortment inference
conducted using genetic sequences of one out of four segments. This revealed that
taking into account segment reassortment and using sequencing data from several
viral segments for joint phylodynamic inference leads to different estimates for
effective population sizes, migration and evolutionary rates, and the height of a
segment tree root node.
The discussed model is implemented as Structured COalescent with REassortment
(SCORE) package for BEAST 2 and its source code available at

description: Multiple systems estimation strategies have recently been applied to quantify hard-to-reach populations, particularly when estimating the number of victims of human trafficking and modern slavery. In such contexts, it is not uncommon to see sparse or even no overlap between some of the lists on which the estimates are based. These create difficulties in model fitting and selection, and we develop inference procedures to address these challenges. The approach is based on Poisson log-linear regression modeling. Issues investigated in detail include taking proper account of data sparsity in the estimation procedure, as well as the existence and identifiability of maximum likelihood estimates. A stepwise method for choosing the most suitable parameters is developed, together with a bootstrap approach to finding confidence intervals for the total population size. We apply the strategy to two empirical data sets of trafficking in US regions, and find that the approach results in stable, reasonable estimates. An accompanying R software implementation has been made publicly available. Supplementary materials for this paper are available online.

Effective Field Theories

description: Abstract: Pairs of Standard Model fermions form dimension-3 singlet operators that can couple to new dark sector states. This “fermion portal” is to be contrasted with the lower-dimensional Higgs, vector and neutrino singlet portals. We characterise its distinct phenomenology and place effective field theory bounds on this framework, focusing on the case of fermion portals to a pair of light dark sector fermions. We obtain current and projected limits on the dimension-6 effective operator scale from a variety of meson decay experiments, missing energy and long-lived particle searches at colliders, as well as astrophysical and cosmological bounds. The DarkEFT public code is made available for recasting these limits, which we illustrate with various examples including an integrated- out heavy dark photon.

Ballistic Spin Injection from Fe into ZnSe and GaAs with a (001), (111), and (110) orientation

description: We present first-principles calculations of ballistic spin injection in Fe/GaAs and Fe/ZnSe junctions with orientation (001), (111), and (110). We find that the symmetry mismatch of the Fe minority-spin states with the semiconductor conduction states can lead to extremely high spin polarization of the current through the (001) interface for hot and thermal injection processes. Such a symmetry mismatch does not exist for the (111) and (110) interfaces, where smaller spin injection efficiencies are found. The presence of interface states is found to lower the current spin polarization, both with and without a Schottky barrier. Finally, a higher bias can also affect the spin injection efficiency.

description: This resource includes paper-and-pen material meant to stimulate lexical-semantic abilities for experimental purposes.The material consists of three 1-page stories (i.e., 300-400 words each) about Mount Kilimanjaro, the Roswell Incident and the Challenger Expedition. Each story is provided in two versions: a "control" (or EASY) version, and an "experimental" (or HARD) version in which 150 terms (50 per story) were replaced with a synonym/alternative word characterised by a lower frequency of use, as per published UK normative data (doi: 10.1080/17470218.2013.850521). All frequency scores are included in the file.The material can be used to stimulate linguistic skills, but also memory processes (such as semantic memory), or executive functioning (such as set-shifting) for the purposes of an experimental manipulation. The rationale at the basis of the manipulation posits that exposure to the experimental condition will require deeper lexical semantic processing than exposure to the control condition, and this will in turn lead to better performance on a task administered immediately after.The procedure of administration is described in the document.The document also includes a brief demographic questionnaire.
The Impact of Agriculture and Farm Produce Prices on Human Capital Formation: Education Decisions of Young Americans in Agricultural Areas Before and During the Food Crisis 2000-2010

description: This study estimates the short-run effects of the structure of the local economy on high school dropout rates in agricultural areas in the United States from 2000 to 2010. Repeated cross-sections of census data are matched to state-level agricultural price indices and data on the regional composition of employment. Some authors theorise that human capital and land are substitutes, and increasing returns to land-intensive activities may lower human capital investments. I do not find empirical evidence of this in the rural United States. In fact, I find some evidence that as agriculture becomes more lucrative young people in areas with very high levels of agricultural employment become more likely to stay in school, not less, relative to those in areas with little or no agriculture within each state.
