Smart and networking underwater robots in cooperation meshes : the swarms ECSEL : H2020 project

The work presented on this paper is aimed to explain the role that unmanned underwater vehicles (AUVs/ROVs) plays in the ECSEL-H2020 SWARMS project. The main goal of the project is to reduce the operational cost and increase the safety of tasks assigned to divers in these operations. This will be achieved enabling the AUVs/ROVs to work in a cooperative mesh. The challenge is to design and develop an integrated platform (a set of Software/Hardware components), incorporated into the current generation of underwater vehicles in order to improve autonomy, cooperation, robustness, cost-effectiveness, and reliability of the offshore operations. The first demonstration of the project will be performed at PLOCAN (Oceanic Platform of the Canary Islands) where these technologies will be validated on its first stage.Peer Reviewe

UM MÉTODO PARA APOIAR A CAPTURA DE INCIDENTES PARA ANÁLISE DE EMERGÊNCIAS

The organizations responsible to emergency management seek to improve their processes and response time, supported by operational plans where responsibilities and actions to be performed on are defined. However, incidents defined as adverse events and unexpected changes in the emergency plan often occur. The knowledge that team members develop dealing with these incidents is very valuable for the organizations. This paper presents the development of a capturing method of incidents not covered by the emergency plans to be implemented on the ongoing emergency through of observational techniques derived from Ethnography, Cognitive Task Analysis (CTA), and Critical Incident Technique (ICT) combined with elements of command and control.As organizações encarregadas da gestão de emergências procuram melhorar seus processos e o tempo de resposta apoiadas em planos operacionais onde são definidas responsabilidades e ações a serem executadas. Entretanto, muitas vezes ocorrem incidentes entendidos como eventos adversos e alterações não previstas pelo plano de emergência. O conhecimento que os membros das equipes desenvolvem ao lidar com estes incidentes é muito valioso para estas organizações. Neste trabalho é apresentado o desenvolvimento de um método de captura de incidentes não previstos pelo plano de emergência a ser aplicado no andamento da mesma através de técnicas observacionais oriundas da Etnografia, Análise de Tarefas Cognitivas (ATC), e Técnica do Incidente Crítico (TIC) combinadas com elementos de comando e controle

Integrative metabolomics to identify molecular signatures of responses to vaccines and infections

Approaches to the identification of metabolites have progressed from early biochemical pathway evaluation to modern high-dimensional metabolomics, a powerful tool to identify and characterize biomarkers of health and disease. In addition to its relevance to classic metabolic diseases, metabolomics has been key to the emergence of immunometabolism, an important area of study, as leukocytes generate and are impacted by key metabolites important to innate and adaptive immunity. Herein, we discuss the metabolomic signatures and pathways perturbed by the activation of the human immune system during infection and vaccination. For example, infection induces changes in lipid (e.g., free fatty acids, sphingolipids, and lysophosphatidylcholines) and amino acid pathways (e.g., tryptophan, serine, and threonine), while vaccination can trigger changes in carbohydrate and bile acid pathways. Amino acid, carbohydrate, lipid, and nucleotide metabolism is relevant to immunity and is perturbed by both infections and vaccinations. Metabolomics holds substantial promise to provide fresh insight into the molecular mechanisms underlying the host immune response. Its integration with other systems biology platforms will enhance studies of human health and disease

Short Sales Constraints and Financial Stability: Evidence from the Spanish 2011 Ban

This paper studies the main effects of the short sales ban implemented in August 2011 in the Spanish stock market along two dimensions: financial stability and market performance. Regarding the first, we show that short positions were a significant determinant of the probability of default of medium-sized banks before the ban. We find that, by weakening the contagion effect coming from the sovereign risk, the ban helped stabilise the probability of default of medium-sized banks, an effect which is not significant in the case of the largest banks and non-financials. Nonetheless, the stabilising power of the ban came at the cost of a large decline in the relative liquidity, trading volumes and price information efficiency of medium-sized banks stocks

Smart sensing interoperability platforms in the scope of Atlantos

This paper aims to demonstrate the capabilities of a Smart Cable which aims to convert any commercial non-PUCK-enabled sensor in a Smart PUCK-enabled device. Through this development, it can be easily integrated on a sensor web platform in order to access the data in real time, and so there is no need to rely on each sensor manufacturer to comply with Sensor Web Enablement standards. The results presented in this paper were acquired during some real field experiments performed between the 24th and 28th of September at PLOCAN facilities in Gran Canaria. During these days three Turner Designs Cyclops sensors were successfully integrated and tested in a mission using an observing surface vehicle such as the Wave Glider SV-2.Peer Reviewe

Evaluación de la nodulación espontanea en Vicia angustifolia en el pedemonte tucumano

Vicia angustifolia es una especie leguminosa que se ha naturalizado en la región del pedemonte tucumano debido a su producción de semillas y al poder de resiembra. Su crecimiento es inverno primaveral, de allí su oportunidad de uso en la producción animal, dado que concuerda con lo que se conoce como “el bache forrajero". Es muy palatable en verde por animales rumiantes (bovinos y caprinos). Esta leguminosa en nuestra región no ha sido evaluada ni mejorada. El objetivo específico en el presente trabajo es evaluar la capacidad de Vicia angustifolia de nodular espontáneamente en tres momentos de la estación de crecimiento (altura de la plata) con la caracterización de los nódulos por cantidad, ubicación (entre la raíz primaria y secundarias) y actividad. Se utilizaron ejemplares obtenidos en condiciones de campo en el predio Finca El Manantial, Facultad de Agronomía y Zootecnia (UNT). La totalidad de las plantas presentaron sistemas radiculares con nódulos. El análisis estadístico de los datos registrados se realizó con un modelo lineal generalizado de la familia binomial con función de enlace logit. Los resultados obtenidos pusieron en evidencia que la mayor proporción de nódulos activos se dan en la raíz primarias cuando las plantas son pequeñas (<10 cm) y, caso contrario, en las raíces secundarias cuando las plantas son medianas (10-20 cm) y grandes (>20 cm). Se considera que, por su capacidad para nodular espontáneamente, Vicia angustifolia tiene potencial como recurso para la alimentación del ganado y que la cantidad, ubicación y actividad de los nódulos esta correlacionada con la altura de la planta o sea con el avance de la estación de crecimientoFil: Martínez, R.E..

Intermittent maser flare around the high mass young stellar object G353.273+0.641 I: data & overview

We have performed VLBI and single-dish monitoring of 22 GHz H$_{2}$O maser emission from the high mass young stellar object G353.273+0.641 with VERA (VLBI Exploration of Radio Astrometry) and Tomakamai 11-m radio telescope. Two maser flares have been detected, separated almost two years. Frequent VLBI monitoring has revealed that these flare activities have been accompanied by structural change of the prominent shock front traced by H2O maser alignments. We have detected only blue-shifted emissions and all maser features have been distributed within very small area of 200 $\times$ 200 au$^{2}$ in spite of wide velocity range (> 100 km s$^{-1}$). The light curve shows notably intermittent variation and suggests that the H$_{2}$O masers in G353.273+0.641 are excited by episodic radio jet. The time-scale of \sim2 yr and characteristic velocity of \sim500 km s$^{-1}$ also support this interpretation. Two isolated velocity components of C50 (-53 \pm 7 km s$^{-1}$) and C70 (-73 \pm 7 km s$^{-1}$) have shown synchronised linear acceleration of the flux weighted V_{\rmn{LSR}} values (\sim-5 km s$^{-1}$ yr$^{-1}$) during the flare phase. This can be converted to the lower-limit momentum rate of 1.1 \times 10$^{-3}$ M_{\sun} km s$^{-1}$ yr$^{-1}$. Maser properties are quite similar to that of IRAS 20126+4104 especially. This corroborates the previous suggestion that G353.273+0.641 is a candidate of high mass protostellar object. The possible pole-on geometry of disc-jet system can be suitable for direct imaging of the accretion disc in this case.Comment: 13 pages, 5 figures accepted for publication in MNRA
