Exact time-localized solutions in Vacuum String Field Theory

We address the problem of finding star algebra projectors that exhibit localized time profiles. We use the double Wick rotation method, starting from an Euclidean (unconventional) lump solution, which is characterized by the Neumann matrix being the conventional one for the continuous spectrum, while the inverse of the conventional one for the discrete spectrum. This is still a solution of the projector equation and we show that, after inverse Wick-rotation, its time profile has the desired localized time dependence. We study it in detail in the low energy regime (field theory limit) and in the extreme high energy regime (tensionless limit) and show its similarities with the rolling tachyon solution.Comment: 27 pages, 2 figures. v2: typos corrected, ref added, comment added in last section, to appear on NP

Bubbling AdS and Vacuum String Field Theory

We show that a family of 1/2--BPS states of $\N=4$ SYM is in correspondence with a family of classical solutions of VSFT with a $B$--field playing the role of the inverse Planck constant. We show this correspondence by relating the Wigner distributions of the $N$ fermion systems representing such states, to low energy space profiles of systems of VSFT D-branes. In this context the Pauli exclusion principle appears as a consequence of the VSFT projector equation. The family of 1/2--BPS states maps through coarse--graining to droplet LLM supergravity solutions. We discuss the possible meaning of the corresponding coarse graining in the VSFT side.Comment: 23 pages, subsection 4.1 added, Appendix suppressed. to be published in NP

TRY plant trait database – enhanced coverage and open access

Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits—almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

O agente comunitário de saúde e aconsolidação do Sistema Único de Saúde: reflexões contemporâneas The community health agent and the consolidation of the Unified Health System: contemporary reflections

Os agentes comunitários de saúde (ACS) são personagens-chave na implantação de políticas voltadas para a reorientação do modelo de saúde, tendo como base a atenção primária. Este estudo apresenta uma revisão de literatura, dirigida à análise crítica sobre a contribuição deste profissional para a consolidação do Sistema Único de Saúde (SUS). Considerando que as concepções acerca do processo saúde-doença dão sentido à prática sanitária e às ações dos profissionais de saúde, inicialmente discutiu-se a evolução dos paradigmas sanitários e a influência das correntes de pensamentos neste processo, apresentando as principais diferenças entre o paradigma flexneriano e o paradigma da produção social da saúde. Neste contexto, o SUS desponta como um novo sistema de saúde, com princípios e diretrizes que configuram o Programa Saúde da Família como estratégia revolucionária, por apresentar respostas aos problemas não solucionados pelo sistema sanitário hegemônico, baseado no paradigma até então dominante. Assim, por colocar em foco o cuidado, a atenção primária, a prática sanitária da vigilância à saúde e o trabalho em equipe multiprofissional, a formação dos profissionais para a abordagem do processo saúde-doença com enfoque em saúde da família surge como desafio para o êxito do modelo sanitário proposto. Destarte, a reflexão crítica sobre a função do ACS aponta para conflitos entre pressupostos teóricos do modelo e a prática deste profissional, destacando a necessidade de capacitação permanente, crítico-reflexiva e baseada em metodologias problematizadoras, como estratégia de potencialização para a efetiva mudança do modelo de saúde, no contexto da práxis do PSF.<br>The community health agents (ACS) are key players in the implementation of policies related to the reorientation of health model, based on primary care. This study presents a literature review, led to critical analysis on the contribution of this work for the consolidation of the Unified Health System (SUS). Whereas the conception of health-disease process gives meaning to the practice and actions of health professionals, first we discussed the evolution of the paradigms of health and the influence of currents of thought in this process, presenting the main differences between the paradigm and Flexnerian paradigm of social production of health. In this context, the SUS emerged as a new health system, with principles and guidelines that make up the Family Health Program a revolutionary strategy which presents answers to the unsolved problems by the hegemonic health system, based on the paradigm dominant so far. So, focusing on care, primary care, health surveillance practices and multi-professional teamwork, professional training to address the health-disease process with a focus on family health poses a challenge to the success of the proposed public health model. Thus, critical reflection on the role of the ACS points to conflicts between the theoretical model and professional practice, highlighting the need for ongoing training, critical and reflective and based on questionable methodology, such as augmentation strategy for the effective change in the health model in the context of the praxis of the Family Health Program

Guidelines for the use of flow cytometry and cell sorting in immunological studies (second edition)

These guidelines are a consensus work of a considerable number of members of the immunology and flow cytometry community. They provide the theory and key practical aspects of flow cytometry enabling immunologists to avoid the common errors that often undermine immunological data. Notably, there are comprehensive sections of all major immune cell types with helpful Tables detailing phenotypes in murine and human cells. The latest flow cytometry techniques and applications are also described, featuring examples of the data that can be generated and, importantly, how the data can be analysed. Furthermore, there are sections detailing tips, tricks and pitfalls to avoid, all written and peer-reviewed by leading experts in the field, making this an essential research companion
