description: We apply heat kernel techniques in N=1 superspace to compute the one-loop effective action to order $F^5$ for chiral superfields coupled to a non-Abelian super Yang-Mills background. The results, when combined with those of hep-th/0210146, yield the one-loop effective action to order $F^5$ for any N=2 super Yang-Mills theory coupled to matter hypermultiplets.

description: Each day, each and every one of us becomes consumers; every selection done, gives direction to the market and the economy inside the country and worldwide. Today, we have the freedom to choose from a variety of products and brands that cover our needs and desires, but rarely, we stop to think about the people and the process that made possible the arrival of these products to the shelves where they are displayed. The truth is that the system leading the global supplies market is controlled by 20 corporations. In this system, the producer does not always obtain the payment that may suit the value of their done hard work in order to get the product, marginalizing the access of a decent life. The aim of this paper is to characterize an alternative trade system: "Fair Trade", which seeks to reward the producer for his work integrating the products price, the social, economic and environmental costs.

description: Local scalar QFT (in Weyl algebraic approach) is constructed on degenerate semi-Riemannian manifolds corresponding to Killing horizons in spacetime. Covariance properties of the $C^*$-algebra of observables with respect to the conformal group $PSL(2,\bR)$ are studied.It is shown that, in addition to the state studied by Guido, Longo, Roberts and Verch for bifurcated Killing horizons, which is conformally invariant and KMS at Hawking temperature with respect to the Killing flow and defines a conformal net of von Neumann algebras, there is a further wide class of algebraic (coherent) states representing spontaneous breaking of $PSL(2,\bR)$ symmetry. This class is labeled by functions in a suitable Hilbert space and their GNS representations enjoy remarkable properties. The states are non equivalent extremal KMS states at Hawking temperature with respect to the residual one-parameter subgroup of $PSL(2,\bR)$ associated with the Killing flow. The KMS property is valid for the two local sub algebras of observables uniquely determined by covariance and invariance under the residual symmetry unitarily represented. These algebras rely on the physical region of the manifold corresponding to a Killing horizon cleaned up by removing the unphysical points at infinity (necessary to describe the whole $PSL(2,\bR)$ action).Each of the found states can be interpreted as a different thermodynamic phase, containing Bose-Einstein condensate,for the considered quantum field. It is finally suggested that the found states could describe different black holes.

description: Goat production in Mexico is important by the amount of rural families who depend on this one, whom considered by the INEGI are 250 thousands. Nevertheless; traditionally, to support the activity, the Mexican government through SAGARPA considers that all the producers dedicated to goat production have equal technological conditions, and that all are dedicated to produce the same product. The reality is that the producers are different to each other, by regions, organizations and inclusive locally, reason why the type of supports that canalize themselves must be agreed to its needs and characteristics. The intention of this work is to present/display the projection of the economic and financial viability of a producing URP of milk and cabrito under an extensive production system formed for a cattle ranch of 100 belly of goats for period 2008-2018, in the municipality of Lerdo, Durango, located in the named Region Lagunera, taking as base year the economic behavior of the URP on 2008 and from it to identify which technological components must be modified to increase the yield of this productive system. The necessary data to carry out this study and to form the producing URP of milk and cabrito arose from producers panels, conducted in La Loma, Durango ejido. The economic analysis and simulation was carried out in the agri economic model named MexSim, whose results show a positive future behavior.

Growth and distribution of port-based global fishing effort within countries EEZs

Publisher: name: University of British Columbia

description: Analyzing spatio-temporal evolution of global fishing effort provides an insight into mechanisms driving fishing effort temporal and spatial expansions. It also enables contrasting fishing effort spatio-temporal trends against the well-documented fact of overall global depletion of major commercial fish stocks. This thesis presents analysis of the evolution and spatial distribution of port-based global fishing effort from 1970 to 2000. A fishing effort spatial distribution prediction model, involving qualitative filter criteria and quantitative weighting of fishing grounds, is developed to predict the spatial distribution of port-based global fishing effort within the EEZs of countries. Countries of the world were grouped into four regions for regional analysis and then pooled for an overall analysis of global spatio-temporal trends. The results of the analyses showed that, on global scale, effective fishing effort grew by 600% in the period between 1970 and 2000. This growth led to reduction of total catch per unit of effort (CPUE) by 80% over the same period. The results of the prediction of spatial distribution of port-based global fishing effort showed that the distribution of global fishing effort covered the continental shelves of the world's ocean in the 1990s, with intensely fished areas clustered along the coasts of major fishing nations. On top of offshore range expansion, the results revealed that the centers of massive fish catch and effort concentrations have gradually moved southward by 20° and 10° respectively. Additionally, fuel consumption rate of port-based global fishing fleets was estimated, using an independent estimate of global fisheries fuel consumption. The result gave a fuel consumption rate of 0.1-0.3 liters per horsepower-hour. When this rate is applied to time-series of global fishing fleet, the result showed that the fuel consumption of global fishing fleet grew by 85% between 1970 and 2000.

In this model, particles cross each bond at rate $N^2$, except one particular bond, the slow bond, where the rate is $N$. Above, $N$ is the scaling parameter. This model has been considered in the context of hydrodynamic limits, fluctuations and large deviations. We investigate moderate deviations from hydrodynamics and obtain a moderate deviation principle.

description: Recent studies provide evidence for the multi-scale nature of magnetic turbulence in the plasma sheet. Wavelet methods represent modern time series analysis techniques suitable for the description of statistical characteristics of multi-scale turbulence. Cluster FGM (fluxgate magnetometer) magnetic field high-resolution (~67 Hz) measurements are studied during an interval in which the spacecraft are in the plasma sheet. As Cluster passes through different plasma regions, physical processes exhibit non-steady properties on magnetohydrodynamic (MHD) and small, possibly kinetic scales. As a consequence, the implementation of wavelet-based techniques becomes complicated due to the statistically transitory properties of magnetic fluctuations and finite size effects. Using a supervised multi-scale technique which allows existence test of moments, the robustness of higher-order statistics is investigated. On this basis the properties of magnetic turbulence are investigated for changing thickness of the plasma sheet.

description: SWOT analysis is used to define an academic group (CA) and its research lines (LGAC) for the International Agribusiness Bachelor degree program offered by the University of Veracruz (LAI-UV) in Veracruz, Mexico. The current context of agribusiness and agro-industrial CA registered by the Professorship Improvement Program (PROMEP) was analyzed. We identified 12 active CA in Mexico, of which only two are consolidated, two others are in process of consolidation, and the rest are at an initial stage. The numbers of LGAC by CA are very diverse, ranging from one to four. We identified the strengths, weaknesses, opportunities and threats of the LAI-UV program which allowed proposing the creation of the CA "Sustainable Agribusinesses” with one LGAC, namely: Agribusiness and agro-industrial chains. We conclude that the SWOT analysis is a useful tool for identifying areas of research in educational institutions.

description: Some of the most interesting Higgs-production processes at future e+ e- colliders are of the type e+ e- -> f anti-f H. We present a calculation of the complete O(alpha) corrections to these processes in the Standard Model for final-state neutrinos and top quarks. Initial-state radiation beyond O(alpha) at the leading-logarithmic level as well as QCD corrections are also included. The electroweak corrections turn out to be sizable and reach the order of +/-10% and will thus be an important part of precise theoretical predictions for future e+ e- colliders. Furthermore, an overview is given of a technique for a fast and reliable numerical calculation of multi-leg one-loop integrals. The method is numerically stable also for exceptional momentum configurations and easily allows the introduction of complex masses and the calculation of higher orders in the expansion around D=4.

description: The small farm in the region of Evora, one of the actors to whom they are directed many and varied government programs comes from a family that inherited a piece of land or works with other relatives, attend temporal properties, most of them with surface areas less than 15 hectares, sell their products in bulk, at market price. Most of them do not have their own machinery and those who possess it only perform obsolete equipment adaptations. It is proposed to operate within a Research University Center Rural Enterprise Services that fosters innovation, stimulating learning and productive efficiency, where contributions from research are used to spread the technical progress as a necessary condition for the survival of the production units and, in that way, increase competitiveness and innovation capacities in the most backward producers, so this paper seeks a model for those producers to achieve competitiveness through education and training of the family unit. The methodology is qualitative, through social research techniques: semi-structured interviews to representatives of producer organizations and institutions driving technological development, and individual producers. This is expected to contribute to regional development, and start construction of an emerging innovation system, contribute to the formation and training of producers in the region and strengthen ties between the university and the producers.

description: Through the use of "Total Quality Control," it is possible for businesses to generate better products or services at a lower cost, thus becoming top companies. Because of this, we seek to promote the study and application of this technique among agroindustrial companies. This research was conducted in an agroindustrial business devoted to the production of meat products. In order to generate data the UALAE based methodology was utilized as a strategic management tool, which was used to obtain an assessment of the company that subsequently applied the Seven Basic Tools of Quality Management. A questionnaire aimed primarily at the production process was created to complement the aforementioned tools, and finally with the achieved results a design of a Total Quality Control model was developed that served to improve operational procedures of this particular company.

description: The food retail sector is characterized by a competition among multi-market retailers that is highly localized. Multi-store retailers either price discriminate spatially or adopt a uniform pricing strategy among local markets. We analyze theoretically the effects of both pricing strategies (local or uniform) on merger control. We show that when one retailer adopts uniform pricing across stores, the anticompetitive effect of the merger on consumer welfare spreads on markets non directly affected by the merger. In addition, the effect of the merger on directly affected markets is enhanced when these markets are sufficiently more competitive than markets non directly affected by the merger. These results lead to reconsiderate the definition of relevant markets in merger control when one multi-market retailer uses local pricing.

description: Context: Telescopes like the Extremely Large Telescope (ELT) and the Giant Magellan Telescope (GMT) will be used together with extreme adaptive optics (AO) instruments to directly image Earth-like planets. The AO systems will need to perform at the fundamental limit in order to image Earth twins. A crucial component is the wavefront sensor. Interferometric wavefront sensors, such as the Zernike wavefront sensor (ZWFS), have been shown to perform close to the fundamental sensitivity limit. However, sensitivity comes at the cost of linearity; the ZWFS has strong nonlinear behavior. Aims: The aim of this work is to increase the dynamic range of Zernike-like wavefront sensors by using nonlinear reconstruction algorithms combined with phase sorting interferometry (PSI) and multi-wavelength measurements. Methods: The response of the ZWFS is explored analytically and numerically. Results: The proposed iterative (non)linear reconstructors reach the machine precision for small aberrations (<0.25 rad rms). Coupling the nonlinear reconstruction algorithm with PSI increases the dynamic range of the ZWFS by a factor of three to about 0.75 rad rms. Adding multiple wavebands doubles the dynamic range again, to 1.4 radians rms. Conclusion: The ZWFS is one of the most sensitive wavefront sensors, but has a limited dynamic range. The ZWFS will be an ideal second-stage wavefront sensor if it is combined with the proposed nonlinear reconstruction algorithm.

description: Here we comprehensively investigate Landau levels, Hofstadter butterfly and transport properties of a semi-Dirac nanoribbon in a perpendicular magnetic field using a recently developed real-space implementation of the Kubo formula based on Kernel Polynomial Method. A Dirac ribbon is considered to compare and contrast our results for a semi-Dirac system. We find that the Landau levels being non-equidistant from each other for the semi-Dirac case (true for a Dirac as well), the flatness of the energy bands vanishes in the bulk and becomes dispersive for a semi-Dirac ribbon in contrast to a Dirac system. This feature is most discernible for intermediate values of the external field. We further compute the longitudinal ($σ_{xx}$ and $σ_{yy}$) and the transverse or Hall ($σ_{xy}$) conductivities where the Hall conductivity shows a familiar quantization, namely, $σ_{xy} \propto 2n$ (the factor `2' includes the spin degeneracy) which is highly distinct from a Dirac system, such as graphene. We also observe anisotropic behavior in magneto-transport in a semi-Dirac ribbon owing to the dispersion anomalies in two different longitudinal directions. Our studies may have important ramifications for monolayer phosphorene.

description: We theoretically investigate the spin Hall conductivity (SHC) in topological Dirac semimetals (TDSMs) whose Dirac points are protected by rotational symmetry. On the basis of a general phase diagram of the system with time-reversal, inversion and four-fold rotational symmetries, we reveal that the SHC is sensitive to the phase to which the system belong. The phase and the SHC are characterized by the mirror Chern numbers and the presence or absence of gapless bulk Dirac points. It is also found that the representative TDSM Cd$_3$As$_2$ supports a large and negative SHC $σ_{xy}^z\sim -10^4 (\hbar/e) (Ω.\textrm{m})^{-1}$. The principle behind the dependency of SHC on the phase diagram is also explained.

description: This study introduces a novel method for inpainting normal maps using a generative adversarial network (GAN). Normal maps, often derived from a lightstage, are crucial in performance capture but can have obscured areas due to movement (e.g., by arms, hair, or props). Inpainting fills these missing areas with plausible data. Our approach extends previous general image inpainting techniques, employing a bow tie-like generator network and a discriminator network, with alternating training phases. The generator aims to synthesize images aligning with the ground truth and deceive the discriminator, which differentiates between real and processed images. Periodically, the discriminator undergoes retraining to enhance its ability to identify processed images. Importantly, our method adapts to the unique characteristics of normal map data, necessitating modifications to the loss function. We utilize a cosine loss instead of mean squared error loss for generator training. Limited training data availability, even with synthetic datasets, demands significant augmentation, considering the specific nature of the input data. This includes appropriate image flipping and in-plane rotations to accurately alter normal vectors. Throughout training, we monitored key metrics such as average loss, Structural Similarity Index Measure (SSIM), and Peak Signal-to-Noise Ratio (PSNR) for the generator, along with average loss and accuracy for the discriminator. Our findings suggest that the proposed model effectively generates high-quality, realistic inpainted normal maps, suitable for performance capture applications. These results establish a foundation for future research, potentially involving more advanced networks and comparisons with inpainting of source images used to create the normal maps.

description: The article aims to present particular views on family farm in economic and social thought, suggesting that this subject has been attracting growing interest in the research communities of these areas in Brazil, at different times. The trajectory seeks to highlight the way in which many authors emphasized, in their analysis, the nature, characteristics and fundaments of family farming. The research methodology is bibliographic and guided by economics and sociology comparative analysis, aiming a contextualized historical reconstruction, concerning theoretical and empirical approaches on family farming. This methodological procedure brought as a hypothesis that Chayanov’s theory was seminal for countless approaches, with repercussions into different schools of thought, interested in family farming research. In addition, the research method also permits to conjecture about family farm specificities, to constitute, organize and survive throughout history. The text aims to bring some contribution to the current debate on the role and the importance of family farming in the Brazilian countryside, particularly on its resilience in a scenario of productive concentration and rural depopulation. It also suggests that the quality of this discussion depends on: 1) advances in the conceptual area, 2) more empirical research and 3) new looks on sectorial and regional diversity in Brazil and its influence on family farming varieties and arrangements.

description: We introduce an efficient, quasideterministic scheme to generate maximally entangled states of two atomic ensembles. The scheme is based on quantum nondemolition measurements of total atomic populations and on adiabatic quantum feedback conditioned by the measurements outputs. The high efficiency of the scheme is tested and confirmed numerically for ideal photodetection as well as in the presence of losses.

description: The present paper aims at a reflection on the process of building the family farm category in contemporary Brazil. The reflection synthesized here is based on revisiting the main academic papers which have contributed to define the field of reflection of family farming in Brazil, documentary analysis and interviews with leaders and advisors of unionism family farming. It is argued that there were three sets of actors who promoted the construction of the category family farming in Brazil: some academic work that provided the basis for rethinking the theoretical location of this farm in the history and development of the country; State policies and legal regulations that gave visibility and operationally defined as comprising this category, and organizations of family farmers who have identified this category as their project and the use of agriculture as a political identity.

description: This article aims to show the diversity of Brazilian agriculture, which is composed by a highly productive and efficient segment made of corporations, a segment also efficient and profitable, entrepreneurial family, and a segment of poor family farmers or peasants who produce for consumption, lives in the establishment, generates jobs for the children, and that does not migrate because its opportunity cost to migrate is low. The absence of economies of scale in agriculture, the low profitability of activity according to the low turnover of fixed capital, the competitive environment of the agricultural market and the risks affecting the activity (climate, pests and rates), do not cause interest in dominating it by a single sector producers, and this makes room for peaceful coexistence between heterogeneous rural sectors, each with its own logic and its own interests and demands.

description: In spite of many results in quantum information theory, the complex nature of compound systems is far from being clear. In general the information is a mixture of local, and non-local ("quantum") information. To make this point more clear, we develop and investigate the quantum information processing paradigm in which parties sharing a multipartite state distill local information. The amount of information which is lost because the parties must use a classical communication channel is the deficit. This scheme can be viewed as complementary to the notion of distilling entanglement. After reviewing the paradigm, we show that the upper bound for the deficit is given by the relative entropy distance to so-called psuedo-classically correlated states; the lower bound is the relative entropy of entanglement. This implies, in particular, that any entangled state is informationally nonlocal i.e. has nonzero deficit. We also apply the paradigm to defining the thermodynamical cost of erasing entanglement. We show the cost is bounded from below by relative entropy of entanglement. We demonstrate the existence of several other non-local phenomena. For example,we prove the existence of a form of non-locality without entanglement and with distinguishability. We analyze the deficit for several classes of multipartite pure states and obtain that in contrast to the GHZ state, the Aharonov state is extremely nonlocal (and in fact can be thought of as quasi-nonlocalisable). We also show that there do not exist states, for which the deficit is strictly equal to the whole informational content (bound local information). We then discuss complementary features of information in distributed quantum systems. Finally we discuss the physical and theoretical meaning of the results and pose many open questions.

description: This article presents a critical analysis of seven theses about the Brazilian rural area. In the beginning we explain these entire theses, and after then we wrote a very critical analysis that point out some inconsistent and contradictions that we saw in these theses. Finally, we present some general considerations highlighting the importance of this debate, but with the comprehension that this debate should be done according to the rural complexity situation, and without any exclusion of social segments that live in the rural area.

description: Additional file 5: Table S4. The fifteen lipids with highest loadings associated with the direction of each principal component. The first principal component is a contrast between selected TAGs and galactolipids, e.g. DGDG, meaning high values of principal component one (associated with nitrogen depletion), correspond to low galactolipid abundance, but high TAG response. The second principal component can be interpreted as an average of selected lipids (namely LPCs, PCs and DGTSs), thus high values of principal component two (associated with WT and DGAT strains) correspond to high abundance in these lipids.

description: Any search or sampling algorithm for solution of inverse problems needs guidance to be efficient. Many algorithms collect and apply information about the problem on the fly, and much improvement has been made in this way. However, as a consequence of the the No-Free-Lunch Theorem, the only way we can ensure a significantly better performance of search and sampling algorithms is to build in as much information about the problem as possible. In the special case of Markov Chain Monte Carlo sampling (MCMC) we review how this is done through the choice of proposal distribution, and we show how this way of adding more information about the problem can be made particularly efficient when based on an approximate physics model of the problem. A highly nonlinear inverse scattering problem with a high-dimensional model space serves as an illustration of the gain of efficiency through this approach.

description: We describe a phase transition for long-range entanglement in a three-dimensional cluster state affected by noise. The partially decohered state is modeled by the thermal state of a suitable Hamiltonian. We find that the temperature at which the entanglement length changes from infinite to finite is nonzero. We give an upper and lower bound to this transition temperature.

description: This article aims to analyze the trajectory of construction of public policies for family farming in Brazil, trying to emphasize the “generation” or public policy referentials strengthened in some key moments, the way these benchmarks were built and the relations between state and civil society. The analysis points to the emergence, in different periods and contexts, of three generations or public policy benchmarks for family farming, the first being guided by strengthening the agricultural and agrarian bias of these social group; the second focusing on social and welfare policies, and the third, by building market devices for food and nutritional security and enviromental sustainability. This analysis also highlights that the relations between state and civil society have changed and become more complex over time. From criticism and claiming positions, civil society actors came to be proactive and, more recently, also a partner in the implementation and management public policies. It is noteworthy that the three generations of public policies and various forms of relationship between civil society and state follow and coexist in public arenas till today.

description: Graph comparison is a fundamental operation in data mining and information retrieval. Due to the combinatorial nature of graphs, it is hard to balance the expressiveness of the similarity measure and its scalability. Spectral analysis provides quintessential tools for studying the multi-scale structure of graphs and is a well-suited foundation for reasoning about differences between graphs. However, computing full spectrum of large graphs is computationally prohibitive; thus, spectral graph comparison methods often rely on rough approximation techniques with weak error guarantees. In this work, we propose SLaQ, an efficient and effective approximation technique for computing spectral distances between graphs with billions of nodes and edges. We derive the corresponding error bounds and demonstrate that accurate computation is possible in time linear in the number of graph edges. In a thorough experimental evaluation, we show that SLaQ outperforms existing methods, oftentimes by several orders of magnitude in approximation accuracy, and maintains comparable performance, allowing to compare million-scale graphs in a matter of minutes on a single machine.
