description: Core collapse supernovae are a promising source of detectable gravitational waves. Most of the existing (multidimensional) numerical simulations of core collapse in general relativity have been done using approximations of the Einstein field equations. As recently shown by Dimmelmeier et al (2002a,b), one of the most interesting such approximation is the so-called conformal flatness condition (CFC) of Isenberg, Wilson and Mathews. Building on this previous work we present here new results from numerical simulations of relativistic rotational core collapse in axisymmetry, aiming at improving the dynamics and the gravitational waveforms. The computer code used for these simulations evolves the coupled system of metric and fluid equations using the 3+1 formalism, specialized to a new framework for the gravitational field equations which we call CFC+. In this approach we add new degrees of freedom to the original CFC equations, which extend them by terms of second post-Newtonian order. The corrections for CFC+ are computed solving a system of elliptic linear equations. The new formalism is assessed with time evolutions of both rotating neutron stars in equilibrium and gravitational core collapse of rotating polytropes. Gravitational wave signals for a comprehensive sample of collapse models are extracted using either the quadrupole formula or directly from the metric. We discuss our results on the dynamics and the gravitational wave emission through a detailed comparison between CFC and CFC+ simulations. The main conclusion is that, for the neutron star spacetimes analyzed in the present work, no significant differences are found among CFC, CFC+, and full general relativity, which highlights the suitability of the former.

description: O presente artigo procura mostrar quais são os fatores que levam os produtores rurais de Mato Grosso a plantar a soja transgênica em detrimento da convencional, uma vez que a adoção da soja RR traz mudanças na governança dos produtores dentro dessa cadeia. Apesar de haver indícios de que a soja transgênica vai dominar o mercado nacional, é importante saber se isso já está sendo consolidado em Mato Grosso, pois esse é um dos mais representativos no plantio de soja do Brasil, sendo a região de Sorriso a maior produtora mundial em área dessa commoditie. Como aporte teórico para dar sustentação ao trabalho, utilizou-se a Economia dos Custos de Transação (ECT). Diante dos resultados encontrados junto a alguns produtores de Mato Grosso, pode-se inferir que a área plantada com soja transgênica não aumentará muito na safra 2007/8 e que um dos fatores que levaram ao não aumento dessa área foi a baixa produtividade da soja transgênica frente à convencional.------------------------------------------------This paper shearch to show which is the factors that take the agricultural producers of the Mato Grosso to plant the transgenic soybean in detriment of the conventional, a time that the adoption of soybean RR change the form of governance of the producers inside of this chain. Although to have indications of that the transgenic soybean goes to dominate the market national, it is importante to know if this already is being consolidated in Mato Grosso, since this state is one of most representative in the plantation of soybean of Brazil, being the region of Sorriso world-wide the producing greater of this commoditie in area. As it arrives in port theoretical to give sustentation to the work, we use the Economy of the Costs of Transactions (ECT). Ahead of the joined results together to some producers of Mato Grosso, it can be inferred that the area planted with transgenic soybean will not increase very in harvest 2007/8 and that one of the factors that had led to not increase of this area was low the productivity of the transgenic soybean front to the conventional.

description: O complexo carnes é um dos principais componentes da pauta de exportação brasileira. O objetivo do artigo é analisar a evolução e a competitividade das exportações do complexo carnes brasileiro e os sub-complexos após 1990. Os procedimentos metodológicos envolvem a realização de uma revisão da literatura sobre competitividade e comércio internacional e coleta e tratamento de dados do complexo carnes a partir das bases da FAO, MDIC/SECEX e IBGE, para o cálculo das taxas de crescimento geométrica das exportações do complexo carnes, do índice Herfindahl-Hirschman e a identificação dos fatores de crescimento das exportações do modelo “Constant-Market-Share” no período de estudo. Os resultados permitem inferir o padrão das exportações brasileiras e a competitividade do complexo brasileiro de carnes agregado, de carne bovina, carne de frango, carne suína, carne de eqüinos e carne de perus, entre 1990 e 2005. A existência de competitividade no complexo carnes agregado e nas carnes selecionadas é confirmada a partir da análise dos resultados do modelo CMS dos complexos brasileiros. -------------------------------------------------The meat complex is one of main components of Brazilian exportation. The objective of the research is analyze the evolution and the competitiveness of Brazilian meat complex and sub-complexes after 1990, as well the factors that could determine the Brazilian exportation performance. We used the following methodological procedures: geometric growth ratios with regression, Index Herfindahl-Hirschman and the analysis of exportations growth using “Constant-Market-Share” model, that decomposes the sources of exportations growth in agro-industrial complexes in various components: “world-wide market growth”, “guideline composition of exportation”, “exportation destination” and “competitiveness” and are capable to express the behavior and standard of the exportations in studied period. The results of model CMS allow to infer the existence of high competitiveness in the Brazilian complexes, responsible to found raised market-share in segments of period.

Effective composite-fermion filling factors up to $ν^* = 4$ are visible and higher order composite-fermion states (with four flux quanta attached) start to emerge at the highest fields. Our results show that the quantum mobility of CVD-grown graphene is comparable to that of exfoliated graphene and, more specifically, that the $p/3$ fractional quantum Hall states have energy gaps of up to 30 K, well comparable to those observed in other silicon-gated devices based on exfoliated graphene.

For demonstration, we reproduce the well-known result for the one-loop induced Fayet-Iliopoulos term in rigidly supersymmetric Abelian gauge theory, and generalize it to the case where soft supersymmetry breaking mass terms for the bulk scalar fields are present on the branes.

description: A solução dos problemas na Amazônia não são independentes, mas conectada com outras partes do País e do mundo. A redução dos desmatamentos e queimadas na Amazônia depende do desenvolvimento de atividades agrícolas adequadas nas áreas já desmatadas e que tenham mercado, em vez do uso “sustentável” da floresta e de direitos difusos. Nesse sentido, uma política agrícola teria efeitos mais positivos do que uma política ambiental, que não pode ser efetuada de maneira isolada das demais regiões do País, sob risco de transferir contingentes populacionais de outras localidades. Há necessidade de elevar a produtividade das atividades agrícolas na Amazônia, reduzirem a pressão sobre os recursos naturais com risco de esgotamento, incentivar plantios racionais de recursos extrativos potenciais, substituir as importações de produtos tropicais (seringueira, dendê, cacau, etc.), melhorarem as relações de troca dos produtos amazônicos versus produtos importados da Zona Franca de Manaus, efetuar a recuperação das áreas que não deveriam ter sido desmatadas e plena utilização potencial das áreas já desmatadas, entre outras.--------------------------------------------The solution of the problems in the Amazon is not independent, but connected with other parts of Brazil and the world. The reduction of deforestation and fire in the Amazon depends on the development of appropriate agricultural activities in areas already deforested and that they have market, instead of the “sustainable” use of the forest and of diffuse rights. In that sense, an agricultural policy would have more positive effects than an environmental policy, which cannot be made in an isolated way of the other areas of the country, under the risk of transferring population contingents from other places. There is the need to elevate the productivity of the agricultural activities in the Amazon, to reduce the pressure over the natural resources under exhaustion risk, to motivate rational plantings of potential extractive resources, to substitute the imports of tropical products (rubber, oil palm, cocoa, etc.), to improve the exchange relationship of Amazonian products versus those imported from the Manaus Free Zone, promote the reclamation of areas that should not have been deforested and promote the full potential use of the areas already deforested, among others.

description: We investigate self-avoiding walk models of linear block copolymers adsorbed at a surface and desorbed by the action of a force. We rigorously establish the dependence of the free energy on the adsorption and force parameters, and the form of the phase diagram for several cases, including $AB$-diblock copolymers and $ABA$-triblock copolymers, pulled from an end vertex and from the central vertex. Our interest in block copolymers is partly motivated by the occurrence of a novel mixed phase in a directed walk model of diblock copolymers \cite{Iliev} and we believe that this paper is the first rigorous treatment of a self-avoiding walk model of the situation.

description: When analyzing bilateral trade flow data, zero trade flows are quite common and problematic when a gravity equation is estimated with a log-linear functional form. This has caused many researchers to either ignore the zero trade flows or to replace zero with a small positive number. Both of these actions bias the resulting parameter estimates of the gravity equation. In this study we correct for this misspecification by using the Heckman selection model to estimate the bilateral trade flows for 46 agrifood products, for the period 1990 to 2000, for 52 countries. In our sample, selection bias rarely affects the signs of variables but often has a substantial effect on the magnitude, statistical significance and economic interpretation of the marginal effects. Hence, treating zero trade flows properly is important from both a statistical and an economics perspective.----------------------------------------------------------------------Revised and published as: Haq, Zahoor Ul, Karl Meilke and John Cranfield. 2013. “Selection bias in a gravity model of agrifood trade.” European Review of Agricultural Economics 40(2):331-360.

description: The ferroelectric properties of disorder Pb(Zr$_{0.5}$Ti$_{0.5}$)O$_{3}$ thin films are investigated with Monte Carlo simulations on the basis of a first-principles-derived Hamitonian. It is found that there exists a critical thickness of about three unit cells ($\sim$12 Å) below which the ferroelectricity disappears under the condition that the in-plane polarizations are suppressed by sufficient clamping effect. Above the critical thickness, periodic $180^{\circ}$ stripe domains with out-of-plane polarizations are formed in the systems in order to minimize the energy of the depolarizaing field. The stripe period increases with increasing film thickness. The microscopic mechanism responsible for these phenomena is discussed.

description: This is a talk given at Computers in High Energy Physics in Adelaide, South Australia, Australia in November 2019. It is partially intended to explain the context of DUNE Computing for computing specialists. The DUNE collaboration consists of over 180 institutions from 33 countries. The experiment is in preparation now with commissioning of the first 10kT fiducial volume Liquid Argon TPC expected over the period 2025-2028 and a long data taking run with 4 modules expected from 2029 and beyond. An active prototyping program is already in place with a short test beam run with a 700T, 15,360 channel prototype of single-phase readout at the neutrino platform at CERN in late 2018 and tests of a similar sized dual-phase detector scheduled for mid-2019. The 2018 test beam run was a valuable live test of our computing model. The detector produced raw data at rates of up to ~2GB/s. These data were stored at full rate on tape at CERN and Fermilab and replicated at sites in the UK and Czech Republic. In total 1.2 PB of raw data from beam and cosmic triggers were produced and reconstructed during the six week test beam run. Baseline predictions for the full DUNE detector data, starting in the late 2020's are 30-60 PB of raw data per year. In contrast to traditional HEP computational problems, DUNE's Liquid Argon TPC data consist of simple but very large (many GB) 2D data objects which share many characteristics with astrophysical images. This presents opportunities to use advances in machine learning and pattern recognition as a frontier user of High Performance Computing facilities capable of massively parallel processing.

description: We present a modified version of the Koide formula from a scalar potential model or from a Yukawaon model, based on scalar fields set up in a nonet representation of the SU(3) flavor symmetry in the Standard Model. The Koide's character, which involves the Standard Model fermion mass ratios, is derived from the vacuum expectation value of the nonet field in either model. The scalar potential in the scalar potential model or the superpotential in the Yukawaon model is constructed with all terms invariant under symmetries. The resulting Koide's character, which is modified by two effective parameters, can fit the experimental mass data of charged leptons, up quarks and down quarks. It offers a natural interpretation of the Standard Model fermion mass spectrum.

Section 2 and 3 are presented more clearly. v3: The distinction between mass singular values and eigenvalues is clarified. v4: Quark mass ratios excluding QCD renormalization factors are used to calculate the Koide's character for quarks in concluding remarks.

The lived experience of an eating disorder among gifted female adolescents : a phenomenological study
Creators: name: Bell, Alison J.
Publisher: name: University of British Columbia
Year: 2009

description: Although several recognized experts have alluded to eating disorders among gifted adolescents as an important topic, it has not been explored through rigorous research methodology. Descriptive phenomenological methodology was used to provide an in-depth description of the experience, core themes, and meaning of disordered eating among gifted female adolescents (ages 15-18). The research data were gained through in-depth interviews with six participants. A situated structure, based on the predominant themes for each individual participant, and an in-depth description of the core and common themes of all the participants' experiences of their eating disorders, were developed. These core and common themes were organized into themes and sub-themes, each elaborated on and supported through thick description, interview excerpts, and the words of the participants themselves. The phenomenological description o f the themes provided in-depth exploration of areas previously addressed in the relevant literature such as perfectionism, control, and low self-esteem. Themes that address the profound negative affective response, explicit connection of giftedness to psychological distress, identity issues, emotional restriction, awareness of multifaceted underlying factors, a de-emphasis on weight and thinness, and a sense of purpose and meaning in the eating disorder experience represent original research contributions that extend the current state of knowledge. The previously unexplored themes, and rich description of the lived experience of an eating disorder among gifted adolescents significantly contribute to clinical practice and psychoeducation in both the gifted and eating disorder fields. This study benefits clinicians, parents, researchers, and those who experience eating disorders by offering knowledge of the experience only gained through the perspective of those who struggle with it personally.

description: People at home and trade negotiators in Geneva cannot bargain what they do not understand, and what they bargain must be based on consensual understanding among the relevant actors, whether or not they agree on what to do about it. Consensual understanding is endogenous, arising in an argumentative process of learning structured by constitutive principles of a regime. In a departure from both rationalist and constructivist approaches to negotiation analysis in political science, my goal in this paper is to try to advance analysis of these questions by exploring the contribution that deliberation or arguing makes to learning. My proposition is that something happens at the multilateral negotiation table in addition to bargaining, something that alters either the understanding of themselves and their interests that participants brought to the table, or how they understand the nature of social reality in a domain. Such learning would be endogenous to the negotiations, because it happens through interaction. This approach requires distinguishing simple learning (acquisition of new information about the context, or the preferences of others) from complex learning (new understanding of cause/effect relations in a domain), which also requires distinguishing consensual understanding from a mutual adjustment of positions. I then specify how this model might be susceptible to empirical investigation. I show how individual issues within a negotiation can be treated as cases susceptible to comparative analysis at a moment in time. I explore this possibility in a comparison of the contribution of consensual understanding to the outcome of negotiation of selected issues in the current Doha Round of multilateral trade negotiations in the World Trade Organization. I then infer the results of arguing from the textual deposits left by negotiations in order to assess the presence or absence of consensual understanding. Finally, I attempt to correlate consensual understanding with the negotiation status of the issues as of the end of the failed Doha Round ministerial of July 2008.

description: A collective system of atoms in a high quality cavity can be described by a nonlinear interaction which arises due to the Lamb shift of the energy levels due to the cavity vacuum [Agarwal et al., Phys. Rev. A 56, 2249 (1997)]. We show how this collective interaction can be used to perform quantum logic. In particular we produce schemes to realize CNOT gates not only for two-qubit but also for three-qubit systems. We also discuss realizations of Toffoli gates. Our effective Hamiltonian is also realized in other systems such as trapped ions or magnetic molecules.

We explicitly construct the latter class of solutions by uplifting a class of four-dimensional rotating black holes. We provide a microscopic explanation of the entropy of such black holes by using a charged version of the Cardy formula.

description: Recent empirical studies have estimated the trade flow effect of membership in the World Trade Organization (WTO) and its predecessor, the General Agreement on Tariffs and Trade (GATT). One important, although largely untested, conclusion from this literature is that the GATT/WTO has worked well if we ignore trade in agriculture – one of the institution’s seemingly apparent failures. This article investigates this conclusion using a large panel of agricultural and non-agricultural trade flows, the latter of which serves as our benchmark. The results are impressive: the multilateral institution has delivered significant positive effects on members’ agricultural trade relative to trade between non-members. Further, despite their special and differential treatment, membership has provided important trade flow benefits for developing and least-developed country agricultural exports. These findings are robust across a large number of specifications and slices of the data. Although there are few sectors as politically sensitive, participation in the GATT/WTO appears to be a significant determinant of agricultural trade flows.

description: We investigate the stability of Pexiderized mappings in Banach modules over a unital Banach algebra. As a consequence, we establish the Hyers--Ulam stability of the orthogonal Cauchy functional equation of Pexider type $f_1(x+y)=f_2(x)+f_3(y)$, $x\perp y$ in which $\perp$ is the orthogonality in the sense of Ratz.

description: The degree to which countries are pursuing regional trade agreements (RTAs) has been nothing short of extraordinary. The latest wave of regional integration, however, is “breeding concern” among academics and policymakers as to the extra‐regional effects of these agreements and their impact on North American agricultural exporters who are party to relatively few RTAs in world trade. This study constructs and uses an updated database of agricultural trade flows from 1992‐2008 to shed light on the degree to which outsiders status affects U.S. and Canadian agricultural exports and its competing suppliers. Regarding outsider status, the existing dummy‐variable approach is modified by incorporating region‐specific extra‐bloc trade flow variables to examine the degree to which RTAs divert trade from specific regions of the world, including Canadian agricultural exports. The results are quite illuminating. While RTAs may not be trade diverting on net, all RTAs considered exhibit trade diversion with respect to at least some regions. The results have important policy implications for nations that are not actively participating in the latest wave of regionalism.

On the Nature of Feedback Heating in Cooling Flow Clusters

description: We study the feedback between heating and cooling of the intra-cluster medium (ICM) in cooling flow (CF) galaxies and clusters. We adopt the popular view that the heating is due to an active galactic nucleus (AGN), i.e. a central black hole accreting mass and launching jets and/or winds. We propose that the feedback occurs with the entire cool inner region (r ~2 cool fast and are removed from the ICM before experiencing the next major AGN heating event. We term this scenario "cold-feedback". Some of these blobs cool and sink toward the central black hole, while others might form stars and cold molecular clouds. We derive the conditions under which the dense blobs formed by perturbations might cool to low temperatures (T

description: Obesity problems are no longer limited to the USA as, in recent years, obesity rates in the EU countries have increased dramatically, leading to serious consequences in terms of direct health care costs and productivity losses, and indicating the existence of a negative externality connected with obesity. Several studies have investigated the private and social costs of obesity, and possible interventions to reduce this pathology. Moreover, a number of economic studies deals with the analysis of variables affecting overweight. Following this last approach and focusing on Italy, the purpose of this paper is to analyse the socio-economic variables affecting obesity, by means of a survey conducted on a sample of 955 consumers resident in Lombardy. The sample was stratified by the variables of gender, age, and residence of the interviewees and was representative of the Lombardy population. We used an ordinal regression model as the dependent variable is expressed in terms of BMI ordinal categories. The independent variables in the model are 14, and are connected to socio-demographic characteristics, nutritional claims, food product attributes, consumer healthy life attitude. The results show that the condition of the seriously overweight, and obese people, increases with age, and this is especially so in people over 65 where the obesity rate is quite high. Also gender is correlated with the pathology, those affected being more likely to be men. Furthermore, there is an inverse relation between obesity and education, obesity decreasing with increasing level of education. Therefore, the analysis underlined that disadvantaged social categories are more susceptible to obesity and overweight. Interestingly, it was found that an inverse relation exists between obesity and quality and marketing attributes of food products.

A History of Violence: Testing the ‘Culture of Honor’ in the US South

description: Using historical data on early settlers to the United States, this paper tests and confirms the “Culture of Honor” hypothesis by socio-psychologists Dov Cohen and Richard Nisbett (1994, 1996). This hypothesis argues that the high prevalence of homicides in the US South stems from the fact that it was a frontier region settled by people whose economy was based on herding: the Scotch-Irish. Herding societies develop cultures of honors for reasons having to do with their precariousness: violence is a necessary condition to preserve a reputation for toughness and deter animal theft. Using historical census data on waves of settlers from Europe and relating contemporaneous violence to early Scotch-Irish settlers, this paper provides a test of the link between Scotch-Irish settlers and the culture of honor. The results confirm that high numbers of Scotch-Irish immigrants to the US South by 1790 are associated with higher homicide rates today, including homicides by white offenders. Similar results do not hold for different origins of migrants or other violent crime or offenses. The effect is stronger in counties with high headcounts of pigs and sheep in the 19th century, confirming the herding origin of the culture of honor. An important contribution of this paper is to suggests an instrument for violence, based on past economic occupations and ecological suitability for herding vs. farming.

description: We explore the relationship between litigation rates and the number of lawyers, in a typical supplier-induced demand (SID) frame. Drawing on an original panel dataset for the 169 Italian courts of justice between 2000 and 2007, we first document that the number of lawyers is positively correlated with different measures of litigation rate. Then, using an instrumental variables strategy we find that a 10 percent increase of lawyers over population is associated with an increase between 1.6 to 6 percent in civil litigation rates. Thus, our empirical analysis supports the SID hypothesis for the Italian lawyers: following an increase in their relative number, lawyers may exploit their informational advantage to induce clients to access to courts even when litigation is unnecessary or ineffective.

description: A formalism for determining the massless spectrum of a class of realistic heterotic string vacua is presented. These vacua, which consist of SU(5) holomorphic bundles on torus-fibered Calabi-Yau threefolds with fundamental group Z_2, lead to low energy theories with standard model gauge group (SU(3)_C x SU(2)_L x U(1)_Y)/Z_6 and three families of quarks and leptons. A methodology for determining the sheaf cohomology of these bundles and the representation of Z_2 on each cohomology group is given. Combining these results with the action of a Z_2 Wilson line, we compute, tabulate and discuss the massless spectrum.

description: Despite its success in a wide range of applications, characterizing the generalization properties of stochastic gradient descent (SGD) in non-convex deep learning problems is still an important challenge. While modeling the trajectories of SGD via stochastic differential equations (SDE) under heavy-tailed gradient noise has recently shed light over several peculiar characteristics of SGD, a rigorous treatment of the generalization properties of such SDEs in a learning theoretical framework is still missing. Aiming to bridge this gap, in this paper, we prove generalization bounds for SGD under the assumption that its trajectories can be well-approximated by a \emph{Feller process}, which defines a rich class of Markov processes that include several recent SDE representations (both Brownian or heavy-tailed) as its special case. We show that the generalization error can be controlled by the \emph{Hausdorff dimension} of the trajectories, which is intimately linked to the tail behavior of the driving process. Our results imply that heavier-tailed processes should achieve better generalization; hence, the tail-index of the process can be used as a notion of "capacity metric". We support our theory with experiments on deep neural networks illustrating that the proposed capacity metric accurately estimates the generalization error, and it does not necessarily grow with the number of parameters unlike the existing capacity metrics in the literature.
