    Abstract This work addresses the problem of motion planning for a group of nonholonomic robots under Visible Light Communication (VLC) connectivity requirements. In particular, we consider an inspection task performed by a Robot Chain Control System (RCCS), where a leader must visit relevant regions of an environment while the remaining robots operate as relays, maintaining the connectivity between the leader and a base station. We leverage Mixed-Integer Linear Programming (MILP) to design a trajectory planner that can coordinate the RCCS, minimizing time and control effort while also handling the issues of directed Line-Of-Sight (LOS), connectivity over directed networks, and the nonlinearity of the robots' dynamics. The efficacy of the proposal is demonstrated with realistic simulations in the Gazebo environment using the Turtlebot3 robot platform.

    Abstract Studies involving endophytic fungi aim to identify organisms inhabiting extreme and relatively unexplored environments, as these fungi possess unique characteristics and uncommon biochemical pathways that enable them to produce compounds with biotechnological potential. Among various enzymes, L-Asparaginase is employed in the treatment of Acute Lymphoblastic Leukemia. In this study, we identified endophytic fungi from Sanionia uncinata and Polytrichastrum alpinum collected on King George Island in Antarctica. The fungi were categorized into morphological groups based on their characteristics, molecularly identified, and assessed for L-Asparaginase (L-ASNase) enzyme production. Subsequently, production optimization was conducted. A total of 161 endophytes were isolated from 504 moss gametophytes, with 107 originating from P. alpinum and 54 from S. uncinata. These isolates were categorized into 31 morphotypes. Fungi exhibiting high enzyme production were identified molecularly. Among them, nine identified isolates belonged to the genera Aspergillus, Collariella, Diaporthe, Epicoccum, Peroneutypa, Xylaria, and Trametes. Three of these isolates were identified at the species level through multigene phylogeny, namely Epicoccum nigrum, Collariella virescens, and Peroneutypa scoparia. All 31 fungi were subjected to solid media testing for L-ASNase enzyme production, with 22 isolates demonstrating production capability, and 13 of them produced L-ASNase free from Urease and Glutaminase. The isolates displaying solid media production underwent further testing in liquid media, all of which exhibited enzyme production ranging from 0.75 to 1.29 U g

    Abstract A preguiça-comum (Bradypus variegatus) tem sido vítima das investidas antrópicas desordenadas, o que tem elevado o número de acidentes e doenças para a espécie. Propôs-se com esse estudo, realizar uma descrição das artérias coronárias, assim como apontar os achados histopatológicos do coração do bicho-preguiça, a fim de favorecer o diagnóstico por imagem, semiologia e clínica médica das espécies. Foram dissecados 18 exemplares de B. variegatus obtidos após morte natural. Quinze deles, sendo 5 machos e 9 fêmeas adultas e 1 jovem, foram fixados com formaldeído e conservados em solução salina. Em 2 machos e 1 fêmea, foi injetado, a partir da artéria carótida comum esquerda, látex corado em vermelho, para tornar as coronárias mais evidentes. Na fêmea também foi injetado através da veia jugular externa direita, látex corado em azul, para evitar equívoco na identificação arterial. Os animais tiveram o tórax aberto a fim de avaliar e retirar o coração para descrição detalhada das artérias coronárias. Para análise histopatológica, foram confeccionadas lâminas histológicas oriundas de corações coletados de 4 animais (3 adultos e 1 jovem). Com base nas análises arteriais, as preguiças possuem duas coronárias: uma a direita e uma a esquerda, que irrigam suas respectivas faces. O coração é composto por endocárdio, miocárdio e epicárdio, semelhante aos mamíferos em geral. Todavia, observou-se necroses endocárdicas, de fibras musculares cardíacas, além de degenerações mixomatosas de válvulas e trombos no lúmen vascular. Esses eventos necróticos, mais extensos, estão relacionados a infartos, enquanto os mais discretos podem ser associados a situações de estresse vivenciadas pelos espécimes.

    Abstract This work is concerned with the problem of planning trajectories and assigning tasks for a Multi-Agent System (MAS) comprised of differential drive robots. We propose a multirate hierarchical control structure that employs a planner based on robust Model Predictive Control (MPC) with mixed-integer programming (MIP) encoding. The planner computes trajectories and assigns tasks for each element of the group in real-time, while also guaranteeing the communication network of the MAS to be robustly connected at all times. Additionally, we provide a data-based methodology to estimate the disturbances sets required by the robust MPC formulation. The results are demonstrated with experiments in two obstacle-filled scenarios

    Abstract O poder de negociar e distribuir atenção é um recurso essencial para os meios de comunicação. Durante períodos eleitorais, a exposição midiática tradicionalmente era construída por duas lógicas institucionalizadas: a do jornalismo e da política. Na internet, todavia, outros atores ocupam a cena para criar e circular conteúdos. A disputa pela visibilidade em mídias sociais envolve fontes jornalísticas, políticos, partidos, movimentos sociais, além de veículos jornalísticos nativos digitais, blogueiros e atores emergentes que desafiam as classificações. O objetivo desse artigo é comparar os compartilhamentos obtidos por veículos da imprensa com páginas de esquerda e de direita no Facebook. Esta pesquisa investiga 82.915 publicações realizadas por 30 fan-pages no Facebook durante a eleição de 2018 para compreender o rearranjo do estatuto da visibilidade no sistema midiático híbrido. Resultados indicam que veículos da imprensa jornalística tradicional convertem boa parte de sua audiência para o Facebook e possuem a maior média de seguidores entre as categorias estudadas. A média de compartilhamento, no entanto, é consideravelmente menor, sugerindo uma ameaça à sua hegemonia da concentração da atenção do público. Ao final do artigo, discutimos as implicações dos achados para a comunicação político-eleitoral, indicamos limitações e apontamos possíveis caminhos para outras pesquisas.
