Nonlinear Schrodinger equation with chaotic, random, and nonperiodic nonlinearity

In this paper we deal with a nonlinear Schr\"{o}dinger equation with chaotic, random, and nonperiodic cubic nonlinearity. Our goal is to study the soliton evolution, with the strength of the nonlinearity perturbed in the space and time coordinates and to check its robustness under these conditions. Comparing with a real system, the perturbation can be related to, e.g., impurities in crystalline structures, or coupling to a thermal reservoir which, on the average, enhances the nonlinearity. We also discuss the relevance of such random perturbations to the dynamics of Bose-Einstein Condensates and their collective excitations and transport.Comment: 4 pages, 6 figure

Com o objetivo de apoiar as pesquisas da Embrapa, que visam a seleção e adaptação de novas cultivares de videira para consumo in natura no Submédio do Vale do São Francisco, este trabalho avaliou a aceitação junto híbridos potenciais e de variedades de uvas com semente que não são comumente comercializadas na região

Effect of pressure on the quantum spin ladder material IPA-CuCl3

Inelastic neutron scattering and bulk magnetic susceptibility studies of the quantum S=1/2 spin ladder system IPA-CuCl3 are performed under hydrostatic pressure. The pressure dependence of the spin gap $\Delta$ is determined. At $P=1.5$ GPa it is reduced to $\Delta=0.79$ meV from $\Delta=1.17$ meV at ambient pressure. The results allow us to predict a soft-mode quantum phase transition in this system at P$_\mathrm{c}\sim 4$ GPa. The measurements are complicated by a proximity of a structural phase transition that leads to a deterioration of the sample.Comment: 5 pages, 4 figure

A systematic review of agent-based model for flood risk management and assessment using the ODD protocol

Recently, applications of agent-based model (ABM) have been used to understand the interaction between social and hydrological systems. These systems are dynamic and co-evolving, which can be captured through different decision-making entities in an ABM simulation. Therefore, this review aims to better understand the use of ABM for flood risk management and assessment (FRMA). The review comprises a systematic selection of literature using the PRISMA method, which is then assessed using an adapted version of the overview, design, and detail (ODD) protocol to better understand the ABM model development process for FRMA. The review finds that the use of the ODD protocol was only seen in 25% of the studies. The studies which did not explicitly use the ODD had a comprehensive description of the models, albeit done in a non-standardised way. Modellers continue to face the dilemma between parsimony and the breadth of the model as identified from the design component of the ODD. The hydrological component is mainly captured in the sub-model process of the ODD, however, improvements in the definition of the sub-model component may warrant a more comprehensive description of the processes and facilitate comparison across studies. The applications of ABM have shown promise to understand long term flood risks, test the efficacy of policies and better understand the factors that affect warning response during the flood evacuation process. ODD adopted for this review may consequently allow for the adoption and more coherent use of the protocol to document models in FRMA

A entrega de um filho em adoção e as vicissitudes de ser mãe

This study aimed to investigate the feelings and experiences of motherhood of a woman who delivered two daughters for adoption. Furthermore, investigate their experiences in relation to her other children not delivered and with the condition of being a mother in this context. Using a semi-structured interview, we conducted a single case study, qualitative, through clinical report. The main results indicated the social and emotional vulnerability of the participant as an important influence on the delivery and a differentiation between children who remained in their care and daughters delivered for adoption. It was also noted the maternal role strongly related to maternal care and the different emotional reactions to experiences of delivery. We conclude the relevance of providing space for these mothers elaborate their stories, beyond the need for public policies that give legal and emotional support to mothers/families who wish to make delivery of children
