description: In this paper, we first construct the homogeneous $q$-shift operator $\widetilde{E}(a,b;D_{q})$ and the homogeneous $q$-difference operator $\widetilde{L}(a,b; θ_{xy})$. We then apply these operators in order to represent and investigate generalized Cauchy and a general form of Hahn polynomials. We derive some $q$-identities such as: generating functions, extended generating functions, Mehler's formula and Roger's formula for these $q$-polynomials.

description: Georg-August-University Göttingen, Geosciences Center, Germany (1); Keele University, School of Geography, Geology and the Environment, UK (2) Understanding the occurrence, extent, and lithological variability of UHP metamorphic domains is fundamental to plate tectonics and its evolution through geologic time. In the central Saxonian Erzgebirge (Germany), the highest metamorphic conditions are recorded in the “Gneiss-Eclogite Unit”, a heterogeneous nappe comprising MP to UHP rocks. Although extensively investigated, UHP rocks were only locally confirmed by the occurrence of coesite in eclogite (e.g., Massonne 2001, Eur. J. Mineral.; Gose Schmädicke 2018, J. Petrol.) and diamond in paragneiss (e.g., Nasdala Massonne 2000, Eur. J. Mineral). This leads to the major question whether the metamorphic rocks of the area are a product of different peak metamorphic conditions or whether they share a joint P-T path but equilibrated and/or re-equilibrated at a different metamorphic stage. In order to screen the variety of poorly exposed rocks in the area, we present a comprehensive dataset of mineral inclusions occurring in 2100 detrital garnet grains. Based on the findings of diamond, coesite, and nanogranitoid inclusions (including cristobalite, kokchetavite, kumdykolite), and by comparing the chemical composition of detrital garnet with that of garnet from crystalline rocks, we show that (i) UHP rocks occur in a wider area than previously expected, (ii) UHP rocks comprise not only eclogite and paragneiss lenses but also their surrounding felsic country rocks, and (iii) the country rocks extensively re-equilibrated at high-temperature conditions during exhumation (Schönig et al. 2019, Geology; Schönig et al. 2020, Gondwana Res.). Thus, we conclude that the metamorphic rocks of the area were subducted to UHP conditions as a largely coherent slab. The results highlight the potential of detrital garnet to tackle major questions arising in UHP research, even in well-studied regions like the Erzgebirge.

description: In recent years, the infinite time-evolution block decimation (iTEBD) method has been demonstrated to be one of the most efficient and powerful numerical schemes for time-evolution in one-dimensional quantum many-body systems. However, a major shortcoming of the method, along with other state-of-the-art algorithms for many-body dynamics, has been their restriction to one spatial dimension. We present an algorithm based on a \textit{hybrid} extension of iTEBD where finite blocks of a chain are first locally time-evolved before an iTEBD-like method combines these processes globally. This in turn permits simulating the dynamics of many-body systems in the thermodynamic limit in $d\geq1$ dimensions including in the presence of long-range interactions. Our work paves the way for simulating the dynamics of many-body phenomena that occur exclusively in higher dimensions, and whose numerical treatments have hitherto been limited to exact diagonalization of small systems, which fundamentally limits a proper investigation of dynamical criticality. We expect the algorithm presented here to be of significant importance to validating and guiding investigations in state-of-the-art ion-trap and ultracold-atom experiments.

Potential Direct Single-Star Mass Measurement

description: We analyze the lightcurve of the microlensing event OGLE-2003-BLG-175/MOA-2003-BLG-45 and show that it has two properties that, when combined with future high resolution astrometry, could lead to a direct, accurate measurement of the lens mass. First, the lightcurve shows clear signs of distortion due to the Earth's accelerated motion, which yields a measurement of the projected Einstein radius \tilde r_E. Second, from precise astrometric measurements, we show that the blended light in the event is coincident with the microlensed source to within about 15 mas. This argues strongly that this blended light is the lens and hence opens the possibility of directly measuring the lens-source relative proper motion \vecμ_\rel and so the mass M=(c^2/4G)μ_\rel t_E \tilde r_E, where t_E is the measured Einstein timescale. While the lightcurve-based measurement of \tilde r_E is, by itself, severely degenerate, we show that this degeneracy can be completely resolved by measuring the direction of proper motion \vecμ_\rel.

Demand and Price Analysis

description: Um modelo econômico que explica a alocação das disponibilidades do produto entre os períodos de safra e entressafra foi desenvolvido para avaliar o impacto dos instrumentos de sustentação de preços utilizados pelo Governo Federal sobre o mercado de arroz em casca. O modelo é aplicado para analisar a experiência da safra 2004/2005. Os resultados mostram que através das compras diretas o governo é capaz de reduzir a oferta dentro do ano safra, o que faz com que os preços do mercado se elevem. Os contratos de opção de venda, tanto públicos como privados, têm um importante papel na redução do risco de retenção da produção após a safra, garantindo assim, que os preços sigam trajetória compatível com o armazenamento competitivo. A crise que o mercado de arroz viveu na safra 2004/2005 mostra que as dificuldades do governo em liberar os recursos para assegurar a garantia de preços em tempo hábil e na programação dos leilões permanecem.

description: O estudo efetua análise da evolução do perfil das condições de saúde e acesso a serviços em saúde entre as pessoas ocupadas no setor agrícola, industrial e serviços, para o agregado do Brasil e suas grandes regiões entre os anos de 1998 e 2003, procurando destacar as diferenças regionais. A base de dados se constitui de informações extraídas da Pesquisa Nacional por Amostra de Domicílios (PNAD), que nos anos de 1998 e 2003 contemplou em seu Suplemento Especial o tema da Saúde. A análise da condição da saúde e do perfil de acesso e utilização dos serviços em saúde é desenvolvida através de análise exploratória de dados, fundamentada em métodos da estatística descritiva. De um modo geral, verificou-se que não houve substanciais diferenças intersetoriais e regionais quanto ao estado de saúde, obtido através do ponto de vista da própria pessoa. Entre 1998 e 2003 houve um aumento relativo do número de pessoas que declararam possuir o hábito de procurar pelo mesmo serviço de saúde, indicando que uma maior parcela de pessoas foram incorporadas ao sistema de saúde brasileiro, seja privado ou público, em todas as regiões do país. Com relação ao perfil da utilização e financiamento por serviços de saúde, as regiões Norte e Nordeste colocam-se em direções opostas ao estado de São Paulo e regiões Sul e Centro-Oeste. São Paulo, o estado que mais se beneficiou de todo o processo de expansão industrial do país, destaca-se por apresentar financiamento de seus serviços de internação hospitalar através de planos de saúde e pela maior concentração de pessoas possuidores de planos e seguros de saúde. Segue-se a esse estado a região Sul, os demais estados do Sudeste e Centro-Oeste. De modo geral é preciso destacar a inequívoca dependência dos trabalhadores ocupados nos setores industrial e serviços, e principalmente, entre os agricultores, relativamente ao sistema público de saúde, o que implica que o SUS é essencialmente importante no financiamento de saúde entre esses trabalhadores, pois percentuais elevados de pessoas recorrem a esse sistema para atendimento básico de saúde e atendimento de média e alta complexidade.

description: A criação de suínos em escala industrial resulta em intensa produção de dejetos nas propriedades rurais. Essas conseqüências se manifestam no solo, no ar, na fauna, na flora e no ambiente socioeconômico. Nesse contexto, essas externalidades negativas interagem com externalidades positivas. Duas dessas últimas externalidades, são: gastos com preservação do meio ambiente e, em particular em Mato Grosso, a participação no Programa Granja de Qualidade, um instrumento estadual de renúncia fiscal. Neste trabalho, depois de se estimar índices de eficiência técnica com dados de dez suinoculturas situadas em Mato Grosso a partir de função de produção cujas variáveis independentes são consumo de água, de eletricidade e da quantidade de trabalhadores diretamente vinculados no processo produtivo, verifica-se que os gastos com a preservação do meio ambiente exercem efeitos positivos sobre os índices de eficiência técnica, enquanto a participação no Programa Grande de Qualidade, diferentemente da variável anterior, revela-se estatisticamente não significativa.

description: India has enjoyed rapid economic growth over the past forty years, GDP per capita (PPP$) accelerating from less than 1% in the 1970s to over 5.8% in the 2000s. As incomes have risen, consumer demand has shifted from staple grains toward higher valued foods, such as horticultural and livestock products. Indian farmers appear to be meeting these new growth opportunities. But as production shifts, questions are being raised about agriculture’s ability to meet the basic food needs of India’s 1.24 billion citizens. Central to these questions has been the waning impact of cereal grain technologies typified by the Green Revolution. Our purpose is to examine the productivity growth implications of farmers’ decisions to diversify production and to assess new sources of growth in Indian agriculture. In doing so, we construct new production and productivity accounts and evaluate total factor productivity (TFP) growth, from 1980 to 2008, at the national, regional, and state levels. Results suggest renewed growth in aggregate TFP growth despite a slowdown in cereal grain yield growth. TFP growth appears to have shifted to the Indian South and West, led by growth in horticultural and livestock products.

description: Gauge field theories play a central role in modern physics and are at the heart of the Standard Model of elementary particles and interactions. Despite significant progress in applying classical computational techniques to simulate gauge theories, it has remained a challenging task to compute the real-time dynamics of systems described by gauge theories. An exciting possibility that has been explored in recent years is the use of highly-controlled quantum systems to simulate, in an analog fashion, properties of a target system whose dynamics are difficult to compute. Engineered atom-laser interactions in a linear crystal of trapped ions offer a wide range of possibilities for quantum simulations of complex physical systems. Here, we devise practical proposals for analog simulation of simple lattice gauge theories whose dynamics can be mapped onto spin-spin interactions in any dimension. These include 1+1D quantum electrodynamics, 2+1D Abelian Chern-Simons theory coupled to fermions, and 2+1D pure Z2 gauge theory. The scheme proposed, along with the optimization protocol applied, will have applications beyond the examples presented in this work, and will enable scalable analog quantum simulation of Heisenberg spin models in any number of dimensions and with arbitrary interaction strengths.

description: Recently, interesting braneworld cosmologies in the Randall-Sundrum scenario have been constructed using a bulk spacetime which corresponds to a charged AdS black hole. In particular, these solutions appear to `bounce', making a smooth transition from a contracting to an expanding phase. By considering the spacetime geometry more carefully, we demonstrate that generically in these solutions the brane will encounter a singularity in the transition region.

description: Global agriculture must significantly increase production to meet by mid-century the demands for food, feed, and fiber posed by the world’s enlarging population. An important requirement to meeting those demands is a lifting of agricultural total factor productivity (TFP) growth rates. The present analysis evaluates the impact global agricultural TFP growth may have on food security in developing countries over the next decade. The results present an encouraging picture of developing countries’ food security status, especially in Asia and Africa. It finds that a continuation of last decade’s agricultural performance significantly accelerates food security reductions, highlighting the important role agricultural productivity plays in a country’s food security strategy. It also finds that TFP growth alleviates food insecurity primarily through a balanced approach between production and trade in Asia and Latin America but gains in Africa appear heavily tilted toward imports. There are, however, limitations to our approach, such as possible overestimation of import capacity in some countries.

description: This paper employs matching techniques to investigate the effects of facility export status on environmental performance. Using facility-level criteria air emission data in the U.S. manufacturing industry, we find the industry-specific effects of export status on emission intensity, measured by emissions per value of sale. In some industries, there is consistent and robust evidence supporting the superior environmental performance of exporters relative to non-exporters in terms of emission intensity for all criteria air pollutants tracked in the paper. In other industries, we find evidence that exporters appear to have higher emission intensity than non-exporters for some pollutants but not all.

description: In this paper, we use quadratic forms diagonalization methods applied to the function thermodynamic energy to analyze the stability of physical systems. Taylor's expansion was useful to write a quadratic expression for the energy function. We consider the same methodology to expanding the thermodynamic entropy and investigate the signs of the second-order derivatives of the entropy as well as previously to the thermodynamic energy function. The signs of the second-order derivatives to the Helmholtz, enthalpy and Gibbs functions are also analysed. We show the immediate consequences on the stability of physical systems due to the signs or curvatures of the second-order derivatives of these thermodynamic functions. The thermodynamic potentials are presented and constructed pedagogically as well as demonstrated the main mathematical aspects these surfaces. We demonstrate the power of superposition of mathematical and physical aspects to understand the stability of thermodynamic systems. Besides, we provide a consistent mathematical demonstration of the minimum, maximum, and saddle conditions of the potentials. We present here a detailed approach on aspects related to the curvature of the thermodynamic functions of physical interest with consequences on stability. This work can be useful as a part or supplement material of the traditional physics curriculum that requires a solid formation in thermodynamics, particularly about formal aspects on the stability.

description: The purpose of this paper to provide added insight into clustering as it pertains to the United States organic sector. I identify clusters of United States certified organic operations by showing how a formal definition of spatial clusters can emerge from an estimated model that accounts for spatial dependency. I also analyze how county-level variables impact the distribution of certified organic operations while controlling for spatial autocorrelation. My results indicate that the spatial distribution of certified organic operations displays statistically significant spatial autocorrelation as well as spatial heterogeneity. The results also indicate that county-level factors related to policy, economics, demographics, and land assets impact the distribution of certified organic operations. As research on firm and industry agglomeration, in general, typically finds that clustering benefits economic development, the results of this paper provide motivation for further research on the formation and impact of clustering in the U.S. organic sector.

description: We simulate the merger of binary neutron stars and analyze the spectral properties of their gravitational waveforms. For the stars we construct hybrid equations of state (EoSs) with a standard nuclear matter EoS at low densities, transitioning to a state-of-the-art holographic EoS in the otherwise intractable high density regime. Depending on the transition density the characteristic frequencies in the spectrum produced from the hybrid EoSs are shifted to significantly lower values as compared to the pure nuclear matter EoS. The highest rest-mass density reached outside a possible black hole horizon is approximately $1.1 \cdot 10^{15}$ g/cm$^3$, which for the holographic model is below the density of the deconfined quark matter phase.

This creates several challenges such as high communication latency between the end devices and the cloud while making the network busy by sending all the raw data continuously. In this thesis, we propose an alternative architecture for the IoT which processes part of the data in the fog to avoid all raw data to be sent to the cloud. However, the cloud processes intensive data analytics. We conduct a trade-off analysis to show the advantages of applying data fusion closer to the data source and then processing the intensive data analytics algorithms in the cloud. We explore the effectiveness of the available architectures including centralised, decentralised, and distributed architecture to propose the most effective data analytics architecture for the IoT. The trade-off analysisshows the effectiveness of various service decomposition strategies leading to an understanding the various balances between Fog and IoT processing and their effectiveness in data communications reduction and result accuracy allowing achievements of 70% data communication reduction while still achieving approximately 90% accuracy. We propose a service distribution strategy called Most Efficient IoT Node (MEIN), which aims to distribute the services to either cloud nodes or fog nodes based on their capabilities while maintaining the usage of resource in IoT architecture. This strategy selects the best nodes and distributes the services on nodes based on the demands of services and capabilities of nodes.

description: A common property of popular models of quintessence dark energy is the convergence to a common solution from a large range of the initial conditions. We re-examine the popular inverse power-law model of quintessence (where the common solution is dubbed as the 'tracker') with particular attention to the initial conditions for the field and their influence on the evolution. We find that previously derived limits on the parameters of the potential in this model are valid only in a range of initial conditions. A reasonably sharp boundary lies where the initial energy density of the scalar field is equal to that of the background radiation component. An initial quintessence energy density above this equipartition value lead to a solution that will not have joined the tracker solution by the present epoch. These non-tracker solutions possess the property that their present equation of state is very compatible with the observed bounds and independent of the exponent of the potential.

description: This paper adds to the recent literature on state-level incentive programs by evaluating the Quality Jobs Program in Oklahoma, which provides cash payments to businesses relocating to or expanding in the state. 70 communities across the state had a business that received QJ funding between 1994 and 2004, and we use multivariate regressions and matching techniques to compare their growth rates between 1990 and the 2005-09 ACS. The results provide no evidence that the QJ program contributed to growth among Oklahoma communities, but do provide limited evidence that, in comparison to otherwise similar Kansas communities, the program may have resulted in higher levels of income growth.

description: We theoretically investigate the collective excitation of multiple (sub)millimeter-sized ferromagnets mediated by waveguide photons. By the position of the magnets in the waveguide, the magnon-photon coupling can be tuned to be chiral, i.e., magnons only couple with photons propagating in one direction, leading to asymmetric transfer of angular momentum and energy between the magnets. A large imbalance in the magnon number distribution over the magnets can be achieved with a long chain of magnets, which concentrate at one edge. The chain also supports standing waves with low radiation efficiency that is inert to the chirality.

description: Additional file 1 Computational runtimes when testing similarity between presence-absence data upto m=10000. We ran the proposed 4 methods to compute p-values for a wide range of dimension m. For each m, 100 independent simulations are conducted. Note that for m≥1000, the exact solution did not compute in a reasonable time. The bootstrap and measure concentration algorithm (MCA) are orders of magnitude faster than the exact solution. The asymptotic solution is instantaneous regardless of m.

description: Using resonance-enhanced two-photon ionization, we detect ultracold, ground-state RbCs molecules formed via photoassociation in a laser-cooled mixture of 85Rb and 133Cs atoms. We obtain extensive bound-bound excitation spectra of these molecules, which provide detailed information about their vibrational distribution, as well as spectroscopic data on the RbCs ground a^3Σ^+ and excited (2)^3Σ^+, (1)^1Πstates. Analysis of this data allows us to predict strong transitions from observed excited levels to the absolute vibronic ground state of RbCs, potentially allowing the production of stable, ultracold polar molecules at rates as large as 10^7 s^{-1}.

Susceptibility of planetary atmospheres to mass loss and growth by planetesimal impacts: the impact shoreline

description: This paper considers how planetesimal impacts affect planetary atmospheres. Atmosphere evolution depends on the ratio of gain from volatiles to loss from atmosphere stripping f_v; for constant bombardment, atmospheres with f_v<1 are destroyed in finite time, but grow linearly with time for f_v>1. An impact outcome prescription is used to characterise how f_v depends on planetesimal impact velocities, size distribution and composition. Planets that are low mass and/or close to the star have atmospheres that deplete in impacts, while high mass and/or distant planets grow secondary atmospheres. Dividing these outcomes is an fv=1 impact shoreline analogous to Zahnle & Catling's cosmic shoreline. The impact shoreline's location depends on assumed impacting planetesimal properties, so conclusions for the atmospheric evolution of a planet like Earth with f_v~1 are only as strong as those assumptions. Application to the exoplanet population shows the gap in the planet radius distribution at ~1.5R_earth is coincident with the impact shoreline, which has a similar dependence on orbital period and stellar mass to the observed gap. Given sufficient bombardment, planets below the gap would be expected to lose their atmospheres, while those above could have atmospheres enhanced in volatiles. The level of atmosphere alteration depends on the total bombardment a planet experiences, and so on the system's (usually unknown) other planets and planetesimals, though massive distant planets would have low accretion efficiency. Habitable zone planets around lower luminosity stars are more susceptible to atmosphere stripping, disfavouring M stars as hosts of life-bearing planets if Earth-like bombardment is conducive to the development of life.

 This species is probably most similar to M. paucispina, n. sp., M. pacuara (Flint), and M. zamora, n. sp., particularly in having a short dorsal phallic spine with sharply upturned apex and projecting lateral wing-like appendages. It can be distinguished from any of these species by the unusual and diagnostic pair of enlarged spiral endophallic spines.
 Adult —Length of forewing: male ca. 2.0 mm. Forewing venation not evident (pharate adult). Spur formula 0:3:4. Overall color (in alcohol) yellowish-brown. Scale-like setae on wings of male not evident, probably absent.
 Male genitalia —Ventral process of segment VI posteriorly projecting, narrow basally, length about 3½ times width at base. Segment IX with anterolateral margin rounded and distinctly produced in ventral ½, posterolateral margin nearly straight; segment deeply mesally excised dorsally and ventrally, forming lateral lobes, separated dorsomesally by less than ½ width of segment. Tergum X moderate in length, lateral margins subparallel; apex of tergum with deep Vshaped emargination, extending less than ½ length of tergum; apicolateral lobes not evident as such, formed by mesal invagination, apicolateral margin subtruncate; tergum, in lateral view, with weakly projecting ventrolateral lobes, more or less continuous with apicolateral margin. Inferior appendages hardly evident as such, strongly fused to phallic ensemble. Mesal pockets of inferior appendage with short, posterodorsally curved, spine-like, apicoventral projections. Paramere appendage short, narrow, nearly uniform in width, apex acute, extending about same length as apical inflection of dorsal phallic spine; Phallobase with short ventral rod-like projections, not flared apically. Dorsal phallic spine, as viewed laterally, short, strongly upturned in about apical 1/3, apex acute; as viewed dorsally, with distinct lateral wing-like appendages at about midlength. Phallicata very short and weakly sclerotized. Endophallic membrane with pair of prominent lateral, helically coiled, sclerites; phallotremal spines apparently absent.

description: Este trabalho teve como objetivo contribuir para o aumento da renda dos agricultores familiares dos assentamentos de Reforma Agrária de Unai – MG, através do acompanhamento da qualidade do leite com a técnica de contagem bacteriana total e a estruturação de um curso para a capacitação com enfoque na higiene da ordenha; dos utensílios envolvidos nessa; do ordenhador; das instalações e dos animais. O curso foi realizado durante um sábado do mês de junho e durou, aproximadamente, cinco horas, envolvendo os períodos da manhã e da tarde, contando com a participação dos professores, técnicos e de todos os estagiários do projeto Unaí e da Embrapa. A formulação do curso foi realizada de forma a envolver a comunidade e para a compreensão dos resultados. Pode-se perceber a mudança de atitude de muitos agricultores, onde seguiram muitas das medidas ensinadas nas oficinas e mudaram seu estilo de produção, adotando medidas mais higiênicas na hora da ordenha e ainda no armazenamento do leite no latão e aprenderam técnicas para o controle da mastite, permitindo, que o leite produzido em sua propriedade tivesse um decréscimo significativo na contagem bacteriana, resultando em maiores lucros.
