description: Os resultados preliminares do Censo Agropecuário mostraram que o rebanho caprino no Brasil é menor do que apontavam estudos anteriores. Para compreender esse resultado é necessário, entre outros estudos, verificar a evolução do efetivo no período. O objetivo do presente trabalho foi mensurar a concentração do rebanho caprino no Brasil, nos anos de 1995/96 e 2006. Para tanto, utilizou-se a metodologia do índice T de Theil e da análise tabular dos dados. Os resultados demonstraram redução da concentração do rebanho entre as Unidades da Federação. Apesar de se verificar concentração do rebanho pela análise tabular, esta não foi fortemente caracterizada pelo índice T de Theil, que mensurou a distribuição do rebanho em relação à área das Unidades da Federação. -------------------------------------------Preliminary results of the agricultural census showed that the sheep in Brazil is lower than previous studies indicated. This article aims to mensurate goat herd concentration in Brazil, in the years of 1995/96 and 2006. Tabular analysis, estimation of Theil T index were used as the basic analytical techniques for the study. The results showed reduction of the concentration of the goat herd among units of the Federation. Analyzing by Theil index, this concentration was not strongly characterized. They differ because the Theil index consider the relationship between the sheep distribution and the area of the units of the Federation.

description: We discuss the gluing construction of class $\mathcal{S}$ chiral algebras in derived setting. The gluing construction in non-derived setting was introduced by Arakawa to construct a family of vertex algebras of which the associated varieties give genus zero Moore-Tachikawa symplectic varieties. Motivated by the higher genus case, we introduce a dg vertex algebra version $\mathsf{MT}_{\mathrm{ch}}$ of the category of Moore-Tachikawa symplectic varieties, where a morphism is given by a dg vertex algebra equipped with action of the universal affine vertex algebra, and composition of morphisms is given by the BRST reduction. We also show that the procedure taking the associated scheme of gives a functor from $\mathsf{MT}_{\mathrm{ch}}$ to the category $\mathsf{MT}$ of derived Moore-Tachikawa varieties, which would imply compatibility of gluing constructions in both categories.

description: China's construction market has been booming in last decades due to economic growth and the privatization of the housing sector. This construction market is currently dominated by structural materials of concrete, steel, and masonry with little wood use. Wood frame construction is new to the Chinese market and therefore, the acceptance and knowledge of architects, structural engineers, and developers about wood products are important to the successful introduction of wood products in China. This study investigated Chinese specifiers' current knowledge about structural and non-structural wood materials, their perceptions about wood, contributions on material specification, and information sources about new building products and technologies. A mail survey of 800 Chinese specifiers was completed in the major urban areas of Shanghai City, Jiangsu and Guangdong Provinces and 373 responses were received. Results indicated that the major building types in these regions were concrete residential buildings with a height of 4 to 20 stories and 5,000 to 20,000 m² in building space. The market share of wood houses was very small. Engineers had the greatest contribution on structural material specification (42.3%) followed by architects (23.6%). For non-structural material specification, architects had the greatest contribution (43.3%) followed by developers (23.8%) and builders (20.3%). Engineers indicated that they had little knowledge about structural wood products. Architects had slightly more knowledge about non-structural wood materials compared to engineers' knowledge about structural wood materials. Specifiers were most concerned about burning and rotting of wood materials followed by costs and lack of acceptance both by developers and the marketplace. Technical reading and corporate promotional materials were the most important information sources and were used by over 50% of respondents. Other channels, such as manuals, codes and standards, association promotional materials, computerized information, and physical examples, were also used by a substantial number of specifiers. Due to the co-operator's lack of market research experience and the reluctance of professionals to share their knowledge, substantial challenges had were faced in this marketing survey and recommendations were given to facilitate future studies and to improve data quality.

description: We consider a semiconductor quantum-well placed in a wave guide microcavity and interacting with the broadband squeezed vacuum radiation, which fills one mode of the wave guide with a large average occupation. The wave guide modifies the optical density of states so that the quantum well interacts mostly with the squeezed vacuum. The vacuum is squeezed around the externally controlled central frequency $\om_0$, which is tuned above the electron-hole gap $E_g$, and induces fluctuations in the interband polarization of the quantum-well. The power spectrum of scattered light exhibits a peak around $\om_0$, which is moreover non-Lorentzian and is a result of both the squeezing and the particle-hole continuum. The squeezing spectrum is qualitatively different from the atomic case. We discuss the possibility to observe the above phenomena in the presence of additional non-radiative (e-e, phonon) dephasing.

description: An N-component continuous-time dynamic system is considered whose components evolve autonomously all the time except for in discrete asynchronous instances of pairwise interactions. Examples include chaotically colliding billiard balls and combat models. A new efficient serial event-driven algorithm is described for simulating such systems. Rather than maintaining and updating the global state of the system, the algorithm tries to examine only essential events, i.e., component interactions. The events are processed in a non-decreasing order of time; new interactions are scheduled on the basis of the examined interactions using preintegrated equations of the evolutions of the components. If the components are distributed uniformly enough in the evolution space, so that this space can be subdivided into small sectors such that only O(1) sectors and O(1)$components are in the neighborhood of a sector, then the algorithm spends time O (log N) for processing an event which is the asymptotical minimum. The algorithm uses a simple strategy for handling data: only two states are maintained for each simulated component. Fast data access in this strategy assures the practical efficiency of the algorithm. It works noticeably faster than other algorithms proposed for this model.

description: Strongly squeezed light at telecommunication wavelengths is the necessary resource for one-sided device-independent quantum key distribution via fibre networks. Reducing the optical pump power that is required for its generation will advance this quantum technology towards efficient out-of-laboratory operation. Here, we investigate the second-harmonic pump power requirement for parametric generation of continuous-wave squeezed vacuum states at 1550nm in a state-of-the-art doubly-resonant standing-wave PPKTP cavity setup. We use coarse adjustment of the Gouy phase via the cavity length together with temperature fine-tuning for simultaneously achieving double resonance and (quasi) phase matching, and observe a squeeze factor of 13dB at 1550nm from just 12mW external pump power at 775nm. We anticipate that optimizing the cavity coupler reflectivity will reduce the external pump power to 3mW, without reducing the squeeze factor.

description: Massless flows from the coset model su(2)_k+1 \otimes su(2)_k /su(2)_2k+1 to the minimal model M_k+2 are studied from the viewpoint of form factors. These flows include in particular the flow from the Tricritical Ising model to the Ising model. By analogy with the magnetization operator in the flow TIM -> IM, we construct all form factors of an operator that flows to Φ_1,2 in the IR. We make a numerical estimation of the difference of conformal weights between the UV and the IR thanks to the Δ-sum rule; the results are consistent with the conformal weight of the operator Φ_2,2 in the UV. By analogy with the energy operator in the flow TIM -> IM, we construct all form factors of an operator that flows to Φ_2,1. We propose to identify the operator in the UV with σ_1Φ_1,2.

description: Um dos pontos importantes que devem ser atendidos por políticas públicas é como integrar o relacionamento de um determinado setor com a economia global, sendo que a questão a ser resolvida é sobre como gerar possibilidades para que o empresário local possa competir em um ambiente globalizado. A integração com o mercado globalizado é uma realidade para todas as cadeias produtivas dos países em desenvolvimento. Mesmo que não haja uma integração formal, as cadeias produtivas vêm, no mínimo sofrendo a concorrência das redes varejistas que constantemente oferecem produtos novos com origens diversas, dentro ou fora do país. Este estudo visa apresentar uma análise da cadeia produtiva da banana no Estado do Rio de Janeiro e sua interação com as cadeias produtivas globais. É importante que o ambiente de análise se estenda às redes globais de produção e distribuição, como forma de avaliar o impacto que uma determinada região produtiva sofre na competitividade dos seus produtos. Quanto maior for a distância entre a organização da produção local e as cadeias produtivas globais, mais importante será a elaboração de um sistema de inovação local efetivo, que inclua iniciativas coletivas privadas, bem como o suporte de organizações públicas.-----------------------------------------------One of the important issues to be regarded by public policies is how to integrate the relations of a certain sector to the global markets. The matter to be answered is how to create possibilities to the local entrepreneur become competitive in a globalized environment. The integration with global markets is a reality for every product chain at developing countries. Even though there is no formal integration, the local product chains are, at least, suffering the competition of the transnational retail chains that constantly offer products from various origins inside outside the country. This paper aims to present a analysis regarding the banana production chain at Rio de Janeiro State and its interaction with the global product chain. It is important that the analysis environment extends to the global production and distribution network, as a frame to evaluate tha impact suffer by the regional production over its product competitiveness. The biggest is the distance between the local production organization and the global product chains, the more important becomes de creation of an effective local innovation system, which includes collective private initiative, as well as good public policies.

Year: 2004

description: The high-energy scattering amplitude of two colour-singlet quark-antiquark pairs is governed by the correlation function of two Wilson loops, which follow the classical straight lines for quark (antiquark) trajectories. This quantity is expected to be free of IR divergences, differently from what happens for the parton-parton scattering amplitude, described, in the high-energy limit, by the expectation value of two Wilson lines. We shall explicitly test this IR finitness by a direct non-perturbative computation of the loop-loop scattering amplitudes in the (pedagogic, but surely physically interesting) case of quenched QED. The results obtained for the Abelian case will be generalized to the case of a non-Abelian gauge theory with N_c colours, but stopping to the fourth order in perturbation theory. In connection with the above-mentioned IR finitness, we shall also discuss some analytic properties of the loop-loop scattering amplitudes in both Abelian and non-Abelian gauge theories, when going from Minkowskian to Euclidean theory, which can be relevant to the still unsolved problem of the s-dependence of hadron-hadron total cross-sections.

description: O objetivo principal deste trabalho foi estimar custos e lucro líquido nas etapas de campo (incluindo a elaboração de cera de origem) do extrativismo da carnaúba. A coleta dos dados ocorreu ao longo dos anos de 2005 e 2006, por meio de entrevistas abertas e observação de campo, ocasião em que se realizou um diagnóstico amplo do setor. A motivação para esta empreitada é decorrente das dificuldades de obtenção de informações sistematizadas para respaldar cálculos de custos de produção, rentabilidade e lucratividade. Observou-se que a escolha feita pelo produtor na contratação dos serviços em campo implica diretamente no resultado final em termos econômicos, com variações significativas para mais e para menos no lucro final. Nas condições atuais de descapitalização, a maioria dos produtores/rendeiros não tem acesso a recursos de instituições oficiais e, por isso, recorre ao mercado paralelo, a taxas de juros que podem chegar a 8% ao mês. Tal situação, somada à questão tecnológica, inviabiliza a exploração, principalmente quando explora somente a produção de cera de origem. Uma política direcionada para o setor, com juros compatíveis com a realidade, contribuiria para a recuperação no médio e longo prazo. No caso do BNB, os recursos já existem. Mas é preciso encontrar formas que permitam o acesso de uma quantidade maior de extrativistas.----------------------------------------------The main objective of this work was to estimate costs and net profit in the field stages (including the craft of origin wax) of the carnauba extractivism. The data collection took place along the years of 2005 and 2006, through open interviews and field observation. What motivated this work was the difficulty in obtaining systemized information to endorse calculation of production costs, lucrativeness and profitability. In the current condition of decapitalization, the majority of the producers/renter does not have access to financial resources from official institutions and, therefore, has to call upon the parallel market, where they obtain funds at interest rates that can get to 8% per month. This situation, added by the technological matter, makes the exploitation impracticable, mainly when the producer only exploits the production of origin wax. A policy directed to the sector, with interest rates that are compatible with reality would contribute to the recovery in the short and mid terms. In the BNB case, resources already exist, but it’s necessary to find ways that allow access to more extractivists.

description: Planetary systems that show single-transit events are a critical pathway to increasing the yield of long-period exoplanets from transit surveys. From the primary Kepler mission, KIC 5951458b (Kepler-456b) was thought to be a single-transit giant planet with an orbital period of 1310 days. However, radial velocity (RV) observations of KIC 5951458 from the HIRES instrument on the Keck telescope suggest that the system is far more complicated. To extract precise RVs for this $V\approx13$ star, we develop a novel matched-template technique that takes advantage of a broad library of template spectra acquired with HIRES. We validate this technique and measure its noise floor to be 4 - 8 m s$^{-1}$ (in addition to internal RV error) for most stars that would be targeted for precision RVs. For KIC 5951458, we detect a long-term RV trend that suggests the existence of a stellar companion with an orbital period greater than a few thousand days. We also detect an additional signal in the RVs that is possibly caused by a planetary or brown dwarf companion with mass in the range of 0.6 - 82 $M_{\rm J}$ and orbital period below a few thousand days. Curiously, from just the data on hand, it is not possible to determine which object caused the single "transit" event. We demonstrate how a modest set of RVs allows us to update the properties of this unusual system and predict the optimal timing for future observations.

description: The tension wood (TW) properties of a 70 year-old Acer sieboldianum Miq were analyzed by using the G-fiber model which was proposed in our previous paper. The roles of the G-layer on the origins of (1) a high large tensile growth stress, (2) a large longitudinal Young's modulus, and (3) a high longitudinal drying shrinkage in the tension wood xylem were discussed on the basis of the simulations using the G-fiber model. The results suggest that the G-layer generates a high tensile stress in the longitudinal direction during the xylem maturation; the longitudinal Young's modulus of the green G-layer becomes significantly higher than that of the lignified layer; furthermore, the G-layer tends to shrink extraordinarily higher than that of the lignified layer during the moisture desorption.

description: This paper presents the Quanta Prime Sequence (QPS) and its foundational theorem, showcasing a unique class of polynomials with substantial implications. The study uncovers profound connections between Quanta Prime numbers and essential sequences in number theory and cryptography. The investigation highlights the sequence's contribution to the emergence of new primes and its embodiment of core mathematical constructs, including Mersenne numbers, Fermat numbers, Lucas numbers, Fibonacci numbers, the Chebyshev sequence, and the Dickson sequence. The comprehensive analysis emphasizes the sequence's intrinsic relevance to the Lucas-Lehmer primality test. This research positions the Quanta Prime sequence as a pivotal tool in cryptographic applications, offering novel representations of critical mathematical structures. Additionally, a new result linking the Quanta Prime sequence to the Harmonic series is introduced, hinting at potential progress in understanding the Riemann Hypothesis.

description: Opportunity of the solar flares (SF's) prediction observing the solar neutrino fluxes is investigated. In three neutrino generations the evolution of the neutrino flux traveling the coupled sunspots (CS's) which are the SF source is considered. It is assumed that the neutrinos possess both the dipole magnetic moment and the anapole moment while the magnetic field above the CS's may reach the values $10^5-10^6$ Gs, displays the twisting nature and has the nonpotential character. The possible resonance conversions of the solar neutrino flux are examined. Since the $ν_{eL}\to ν_{μL}$ resonance takes place before the convective zone, its existence can in no way be connected with the SF. However, when the solar neutrino flux moves through the CS's in the preflare period, then it may undergo the additional resonance conversions and, as a result, depleting the electron neutrinos flux may be observed.

description: Breast cancer screening plays a pivotal role in early detection and subsequent effective management of the disease, impacting patient outcomes and survival rates. This study aims to assess breast cancer screening rates nationwide in the United States and investigate the impact of social determinants of health on these screening rates. Data on mammography screening at the census tract level for 2018 and 2020 were collected from the Behavioral Risk Factor Surveillance System. We developed a large dataset of social determinants of health, comprising 13 variables for 72337 census tracts. Spatial analysis employing Getis-Ord Gi statistics was used to identify clusters of high and low breast cancer screening rates. To evaluate the influence of these social determinants, we implemented a random forest model, with the aim of comparing its performance to linear regression and support vector machine models. The models were evaluated using R2 and root mean squared error metrics. Shapley Additive Explanations values were subsequently used to assess the significance of variables and direction of their influence. Geospatial analysis revealed elevated screening rates in the eastern and northern United States, while central and midwestern regions exhibited lower rates. The random forest model demonstrated superior performance, with an R2=64.53 and root mean squared error of 2.06 compared to linear regression and support vector machine models. Shapley Additive Explanations values indicated that the percentage of the Black population, the number of mammography facilities within a 10-mile radius, and the percentage of the population with at least a bachelor's degree were the most influential variables, all positively associated with mammography screening rates.

description: The gluon and ghost propagators in Landau Gauge Yang-Mills Theory are investigated. Self-consistent solutions are obtained from their equations of motion above and below the presumed phase transition. Gluon confinement is manifest in these solutions and can be read off the infrared behavior of the gluon and ghost propagators. Confinement prevails below the presumed phase transition. Above and in the infinite temperature limit, a qualitative change is observed: The chromoelectric sector exhibits screening, while long-range chromomagnetic interactions, mediated by soft modes, are still observed. At least part of the gluon spectrum is still confined. These findings agree with corresponding lattice results.

description: O propósito deste artigo é estabelecer uma comparação entre duas cidades importantes no cenário mundial de Clusters Ecológicos, no que se refere à geração de vantagens competitivas locais na Arena Competitiva dos Alimentos e Produtos Naturais e Orgânicos. Os resultados obtidos neste trabalho são decorrentes do emprego de uma visão teórica cunhada por Porter (1999) e complementada por Lima (2003) a respeito da formação de organizações em rede – clusters – em localidades no perímetro dos centros das cidades, com enfoque em produtos associados à idéia de conservação do meio-ambiente e às inovações em seu âmbito, circunscrita pelo método de análise documental. As cidades que integram a arena competitiva a ser tratada neste artigo são respectivamente: Boulder; estado do Colorado- EUA; e cidade do Rio de Janeiro – RJ/Brasil. O segmento em análise é o do varejo especializado circunscrito pela arena competitiva dos alimentos e produtos naturais e orgânicos. Foi verificada a importância da estrutura de governança para a coordenação da cadeia de valores do projeto de criação de vantagens competitivas dos centros das duas cidades.---------------------------------------------The aim of this paper is to establish a comparison between two relevant cities in the world’s ecological clusters context, related with the fostering of competitive advantage of the organic and natural food. The results provided by this paper are generated by the application of a theoretical vision created by Porter (1999) and complemented by Lima (2003) about the formation of network organizations – clusters – in downtown perimeter of the cities, with focus on products related with the environment conservation idea, and the innovations in your sphere, circumscribed by the documental analysis method. The cities that integrate the competitive arena mentioned in this paper are respectively: Boilder; Colorado state – USA; and Rio de Janeiro – RJ/Brazil. The segment of the analysis is the specialized retailer circumscribed by the competitive arena of the organic and natural food. It was verified the importance of the governance structure for the value chain coordination of the project of competitive advantage creation in downtown of the both cities.
The effects of streamside forest harvesting on aquatic macroinvertebrates and rainbow trout (Oncorhynchus mykiss): Diet in the central interior of British Columbia, Canada
Creators: name: Mackenzie, Kirsten Dawn

description: Timber harvesting has the potential to alter stream ecosystems in a variety of ways, impacting stream habitat, food resources, and ambient conditions for a variety of stream biota. While ample attention has been focused on salmonid-bearing streams in the coastal areas of British Columbia, comparatively little research has been applied to the interior regions of the province where climate, topography, and forest practices differ wildly from the wet, mountainous west coast. This thesis investigates the effect of streamside forest harvesting on the benthic and drift macroinvertebrate communities, and on the diets of stream-resident rainbow trout in three small, lake-headed streams in the central interior of B.C. Benthic invertebrate biomass and abundance, community composition, and functional feeding guild composition did not exhibit post-logging changes in the two treatment streams relative to the control. Similarly, the biomass, abundance, community composition, and functional feeding guild composition of the drift invertebrate community did not show marked differences between logged and unlogged streams. Rather, patterns within both of these communities tended to reflect natural temperature differences evident among the streams. Rainbow trout in the two logged streams exhibited significantly lower condition (weight for a given length) than trout in the unlogged control stream. Trout in the control stream ate a greater biomass and abundance of invertebrates than trout in the logged streams. Trout in the control stream also tended to eat larger invertebrates than fish in the logged streams; however, this did not reflect differences in the size of prey items available in the drift. Two families of invertebrates tended to dominate the biomass and abundance of the stomach contents of all fish: Ephemeroptera (mayflies) and Diptera (true flies). Neither the size, abundance, nor biomass of these primary prey organisms were affected by the logging treatment. The unique temperature regimes coupled with density dependence associated with these small lake-headed streams were likely the most important factors in regulating invertebrate communities and fish growth in these small streams.

description: Globally optimal solution describing a phase conjugated field of Raman scattering on the resonant $B\gets X$ transition of iodine $I_2$ is studied. Maximum optical coherence is found as a top eigenvalue problem. A reversibility theorem has been stated. This provides sufficient conditions for a tightly localized waveform and molecular hologram to exist. A noisy picosecond pulse has been computed to show how femtosecond polarization is regained at target time.

Particle sliding on a turntable in the presence of frictional forces

description: Motion of a point particle sliding on a turntable is studied. The equations of motion are derived assuming that the table exerts frictional force on the particle, which is of constant magnitude and directed opposite to the direction of motion of the particle relative to the turntable. After expressing the equations in terms of dimensionless variables, some of the general properties of the solutions are discussed. Approximate analytic solutions are found for the cases in which (i) the particle is released from rest with respect to the lab frame and, (ii) the particle is released from rest with respect to the turntable. The equations are then solved numerically to get a more complete understanding of the motion. It is found that one can define an escape speed for the particle which is the minimum speed required to get the particle to move off to infinity. The escape speed is a function of the distance from the center of the turntable and for a given distance from the center, it depends on the direction of initial velocity. A qualitative explanation of this behavior is given in terms of the fictitious forces. Numerical study also indicates an alternative way for measuring the coefficient of friction between the particle and the turntable.

description: In this paper I study levels and trends in agricultural output and productivity in 14 developing countries that account for a major portion of the Central American and Caribbean population and agricultural output. I make use of data of drawn from the Food and Agricultural Organization of the United Nations and my period study cover the period 1979-2008. The study uses data envelopment analysis (DEA) to derive Malmquist productivity indexes. The study examines trends in agricultural productivity over the period. Issues of catch-up and convergence, or in some cases possible divergence, in productivity in agriculture are examined within a global framework. The results show an annual growth in TFP of 1.5 %, with efficiency change (or catch-up) contributing 0.1 % per year and technical change (or frontier shift) providing the other 1.4 %. In terms of individual country performance, the most spectacular performance is posted by Dominican Republic with an average annual growth of 3.9 % in TFP over the study period. Other countries with strong performance are, among other, Cuba, Barbados, Costa Rica, Panama and Guatemala have posted a TFP growth rate of only 2.9 every one.

description: Using 324 numerically modelled galaxy clusters we investigate the radial and galaxy-halo alignment of dark matter subhaloes and satellite galaxies orbiting within and around them. We find that radial alignment depends on distance to the centre of the galaxy cluster but appears independent of the dynamical state of the central host cluster. Furthermore, we cannot find a relation between radial alignment of the halo or galaxy shape with its own mass. We report that backsplash galaxies, i.e. objects that have already passed through the cluster radius but are now located in the outskirts, show a stronger radial alignment than infalling objects. We further find that there exists a population of well radially aligned objects passing very close to the central cluster's centre which were found to be on highly radial orbit.

description: Kim and Chan have recently observed Non-Classical Rotational Inertia (NCRI) for solid $^4$He in Vycor glass, gold film, and bulk. Their low $T$ value of the superfluid fraction, $ρ_{s}/ρ\approx0.015$, is consistent with what is known of the atomic delocalization in this quantum solid. By including a lattice mass density $ρ_{L}$ distinct from the normal fluid density $ρ_{n}$, we argue that $ρ_{s}(T)\approxρ_{s}(0)-ρ_{n}(T)$, and we develop a model for the normal fluid density $ρ_{n}$ with contributions from longitudinal phonons and ``defectons'' (which dominate). The Bose-Einstein Condensation (BEC) and macroscopic phase inferred from NCRI implies quantum vortex lines and quantum vortex rings, which may explain the unusually low critical velocity and certain hysteretic phenomena.
