Towards Energy Neutrality in Energy Harvesting Wireless Sensor Networks: A Case for Distributed Compressive Sensing?

This paper advocates the use of the emerging distributed compressive sensing (DCS) paradigm in order to deploy energy harvesting (EH) wireless sensor networks (WSN) with practical network lifetime and data gathering rates that are substantially higher than the state-of-the-art. In particular, we argue that there are two fundamental mechanisms in an EH WSN: i) the energy diversity associated with the EH process that entails that the harvested energy can vary from sensor node to sensor node, and ii) the sensing diversity associated with the DCS process that entails that the energy consumption can also vary across the sensor nodes without compromising data recovery. We also argue that such mechanisms offer the means to match closely the energy demand to the energy supply in order to unlock the possibility for energy-neutral WSNs that leverage EH capability. A number of analytic and simulation results are presented in order to illustrate the potential of the approach.Comment: 6 pages.

A inclusão digital como corolário do Direito à Educação: análise dos impactos da pandemia de COVID-19 no Brasil

On March 11, 2021, WHO assessed COVID-19 as a pandemic, disease caused by the new coronavirus. Since then, Brazil, as a society and state, saw itself with the need to revaluate its social structure in its many aspects, especially education. As such, this research aims to analyze digital inclusion as a corollary of the right to education, focusing on the developments and adversities manifested in the teaching-learning processes, carried out by the Internet and Information and Communication Technologies (ICT) in remote education. Initially, the concept of education in the national legal system is presented along with the legal nature and the constitutional foundations of the social right to education, treated as access, permanence and quality, as well as its relationship with digital inclusion. Therefore, the multiple dimensions that aggregate the debate on digital exclusion/inclusion are discussed, followed by the presentation and analysis of concrete data about the student reality in remote education, together with the subsequent discussion on the legal basis for digital inclusion. Finally, considering the thoughts of Paulo Freire and Edgar Morin about education for autonomy and in the planetary society, digital inclusion is analyzed as a corollary right to the right to education based on its humanistic contributions.Trabalho de Conclusão de Curso (Graduação)Em 11 de março de 2020, a Organização Mundial da Saúde decretou o estado de pandemia da COVID-19, doença causada pelo novo coronavírus. A partir de então, o Brasil, enquanto sociedade e Estado, se deparou com a necessidade de reavaliação da estrutura social em seus diversos aspectos, sobretudo na educação. Nesse contexto, a presente pesquisa possui como objetivo analisar a inclusão digital como corolário do direito à educação com enfoque nos desdobramentos e adversidades manifestados nos processos de ensino-aprendizagem protagonizados pela Internet e Tecnologias de Informação e Comunicação (TIC) no ensino remoto. Primeiramente, é apresentado o conceito de educação no ordenamento jurídico pátrio junto à natureza jurídica e os fundamentos constitucionais do direito social à educação, tratado enquanto acesso, permanência e qualidade, assim como sua relação com a inclusão digital. Por conseguinte, são discorridas as múltiplas dimensões que agregam o debate sobre a exclusão/inclusão digital, seguidas pela apresentação e análise de dados concretos acerca da realidade estudantil no ensino remoto, junto a subsequente discussão sobre a fundamentação legal voltada à inclusão digital. Por fim, considerando os pensamentos de Paulo Freire e Edgar Morin acerca da pedagogia da autonomia e da educação na era planetária, passa-se a analisar a inclusão digital como direito corolário ao direito à educação a partir de suas contribuições humanísticas

Dichotomous parvalbumin interneuron populations in dorsolateral and dorsomedial striatum

There are two electrophysiological dichotomous populations of parvalbumin (PV) interneurons located in the dorsal striatum. Striatal PV interneurons in medial and lateral regions differ significantly in their intrinsic excitability. Parvalbumin interneurons in the dorsomedial striatum, but not in the dorsolateral striatum, receive afferent glutamatergic input from cingulate cortex.Stanley Center for Psychiatric Research at the Broad Institute of MIT and Harvard and a doctoral fellowship from the Portuguese Foundation for Science and Technology to P.M.
