2. Aerodynamic imaging by mosquitoes inspires a surface detector for autonomous flying vehicles

Abstract

Some flying animals use active sensing to perceive and avoid obstacles. Nocturnal mosquitoes exhibit a behavioral response to divert away from surfaces when vision is unavailable, indicating a short-range, mechanosensory collision-avoidance mechanism. We suggest that this behavior is mediated by perceiving modulations of their self-induced airflow patterns as they enter a ground or wall effect. We used computational fluid dynamics simulations of low-altitude and near-wall flights based on in vivo high-speed kinematic measurements to quantify changes in the self-generated pressure and velocity cues at the sensitive mechanosensory antennae. We validated the principle that encoding aerodynamic information can enable collision avoidance by developing a quadcopter with a sensory system inspired by the mosquito. Such low-power sensing systems have major potential for future use in safer rotorcraft control systems.

Abstract

International audience; The multidrug-resistant Staphylococcus capitis NRCS-A clone is responsible for sepsis in preterm infants in neonatal intensive care units (NICUs) worldwide. Here, to retrace the spread of this clone and to identify drivers of its specific success, we investigated a representative collection of 250 S. capitis isolates from adults and newborns. Bayesian analyses confirmed the spread of the NRCS-A clone and enabled us to date its emergence in the late 1960s and its expansion during the 1980s, coinciding with the establishment of NICUs and the increasing use of vancomycin in these units, respectively. This dynamic was accompanied by the acquisition of mutations in antimicrobial resistance- and bacteriocin-encoding genes. Furthermore, combined statistical tools and a genome-wide association study convergently point to vancomycin resistance as a major driver of NRCS-A success. We also identified another S. capitis subclade (alpha clade) that emerged independently, showing parallel evolution towards NICU specialization and non-susceptibility to vancomycin, indicating convergent evolution in NICU-associated pathogens. These findings illustrate how the broad use of antibiotics can repeatedly lead initially commensal drug-susceptible bacteria to evolve into multidrug-resistant clones that are able to successfully spread worldwide and become pathogenic for highly vulnerable patients.

Abstract

This paper introduces a complex representation for spacelike surfaces in the Lorentz-Minkowski space $L^4$, based in two complex valued functions which can be assumed to be holomorphic or anti-holomorphic. When the immersion is contained in quadrics of $L^4$, the representation then allows us to obtain interesting partial differential equations with holomorphic or anti-holomorphic parameters, within which we find the partial Riccati Equation. Using then theory of holomorphic complex functions we construct explicitly new local solutions for those PDEs together with its associated geometric solutions. So, several explicit examples are given. As geometric consequence, through of our approach we characterize all conformal totally umbilical spacelike immersions into $L^4$, and in addition, we also show that for each conformal immersion in $L^4$ which satisfies the partial Riccati equation there exists a Bryant immersion in $H^3$, both immersions being congruent by a translation vector.

Abstract

The European Solar Telescope (EST)1 is a research infrastructure for solar physics. It is planned to be an on-axis solar telescope with an aperture of 4m and equipped with an innovative suite of spectro-polarimetric and imaging post-focus instrumentation. The EST project was initiated and is driven by EAST2, the European Association for Solar Telescopes. EAST was founded in 2006 as an association of 14 European countries. Today, as of December 2019, EAST consists of 26 European research institutes from 18 European countries. The Preliminary Design Phase of EST was accomplished between 2008 and 2011. During this phase, in 2010, the first version of the EST Science Requirement Document (SRD)was published. After EST became a project on the ESFRI3 roadmap 2016, the preparatory phase started. This phase is partially supported by EU funding through the PRE-EST H2020 project4. The goal of the preparatory phase is to accomplish a final design for the telescope and the legal governance structure of EST. A major milestone on this path is to revisit and update the Science Requirement Document (SRD). The EST Science Advisory Group (SAG) has been constituted by EAST and the Board of the PRE-EST4 EU project in November 2017 and has been charged with the task of providing with a final statement on the science requirements for EST. Based on the conceptual design, the SRD update takes into account recent technical and scientific developments, to ensure that EST provides significant advancement beyond the current state-of-the-art. The present update of the EST SRD has been developed and discussed during a series of EST SAG meetings: 1st telecon meeting on Nov 5th, 2017 2nd meeting in Freiburg, Nov 24, 2017 3rd telecon meeting, Dec 15, 2017 4th telecon meeting, March 26, 2018 5th meeting in Belfast, April 16 & 17, 2018 6th meeting in Naxos, June 16, 2018 7th telecon meeting, January 14, 2019 8th telecon meeting, October 11, 2019 9th telecon meeting, October 22, 2019 10th telecon meeting, December 3, 2019 The SRD develops the top-level science objectives of EST into individual science cases. Identifying critical science requirements is one of its main goals. Those requirements will define the capabilities of EST and the post-focus instrument suite. The technical requirements for the final design of EST will be derived from the SRD. The science cases presented in Part II (Sects. 1 to 8) are not intended to cover all the science questions to be addressed with EST, but rather to provide a precise overview of the capabilities that will make of EST a competitive state-of-the-art telescope to push the boundaries of our knowledge over the next few decades. The science cases contain detailed observing programmes specifying the type of observations needed to solve specific science problems. An eort is being made to define the parameters of the required observations as accurately as possible, taking into account both present capabilities and technological developments expected in the near future. The tables of the observing programmes corresponding to the science cases are compiled in Sect. 10. The EST science cases represent challenging observations that put strong constraints on the telescope and its instrument suite. Ultimately, they will be translated into Technical Requirement Document (TRD) leading to the final EST design to be implemented during the construction phase. The unique design advantages of the EST concept is presented in Section 11. The eect of the science cases on the EST design are discussed in Section 12 and summarized in Section 13., This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 739 500

Abstract

Cloud computing enables the on-demand delivery of resources for a multitude of services and gives the opportunity for small agile companies to compete with large industries. In the telco world, cloud computing is currently mostly used by Mobile Network Operators (MNO) for hosting non-critical support services and selling cloud services such as applications and data storage. MNOs are investigating the use of cloud computing to deliver key telecommunication services in the access and core networks. Without this, MNOs lose the opportunities of both combining this with over-the-top (OTT) and value-added services to their fundamental service offerings and leveraging cost-effective commodity hardware. Being able to leverage cloud computing technology effectively for the telco world is the focus of Mobile Cloud Networking (MCN) This paper presents the key results of MCN integrated project that includes its architecture advancements, prototype implementation and evaluation. Results show the efficiency and the simplicity that a MNO can deploy and manage the complete service lifecycle of fully cloudified, composed services that combine OTT/IT- and mobile-network-based services running on commodity hardware. The extensive performance evaluation of MCN using two key Proof-of-Concept scenarios that compose together many services to deliver novel converged elastic, ondemand mobile-based but innovative OTT services proves the feasibility of such fully virtualized deployments. Results show that it is beneficial to extend cloud computing to telco usage and run fully cloudified mobile-network-based systems with clear advantages and new service opportunities for MNOs and endusers.

Abstract

Solar observations in the infrared domain can bring important clues on the response of the low solar atmosphere to primary energy released during flares. At present the infrared continuum has been detected at 30 THz (10 $��$m) in only a few flares. In this work we present a detailed multi-frequency analysis of SOL2012-03-13, including observations at radio millimeter and sub-millimeter wavelengths, in hard X-rays (HXR), gamma-rays (GR), H-alpha, and white-light. HXR/GR spectral analysis shows that the event is a GR line flare and allows estimating the numbers of and energy contents in electrons, protons and alpha particles produced during the flare. The energy spectrum of the electrons producing the HXR/GR continuum is consistent with a broken power-law with an energy break at ~800 keV. It is shown that the high-energy part (above ~800 keV) of this distribution is responsible for the high-frequency radio emission (> 20 GHz) detected during the flare. By comparing the 30 THz emission expected from semi-empirical and time-independent models of the quiet and flare atmospheres, we find that most (~80%) of the observed 30 THz radiation can be attributed to thermal free-free emission of an optically-thin source. Using the F2 flare atmospheric model this thin source is found to be at temperatures T~8000 K and is located well above the minimum temperature region. We argue that the chromospheric heating, which results in 80% of the 30 THz excess radiation, can be due to energy deposition by non-thermal flare accelerated electrons, protons and alpha particles. The remaining 20% of the 30 THz excess emission is found to be radiated from an optically-thick atmospheric layer at T~5000 K, below the temperature minimum region, where direct heating by non-thermal particles is insufficient to account for the observed infrared radiation., 22 pages, 7 figures, accepted for publication in Solar Physics

Abstract

Context: Transverse loop oscillations and loop contractions are commonly associated with solar flares, but the two types of motion have traditionally been regarded as separate phenomena. Aims: We present an observation of coronal loops contracting and oscillating following onset of a flare. We aim to explain why both behaviours are seen together and why only some of the loops oscillate. Methods: A time sequence of SDO/AIA 171 \r{A} images is analysed to identify positions of coronal loops following the onset of M6.4 flare SOL2012-03-09T03:53. We focus on five loops in particular, all of which contract during the flare, with three of them oscillating as well. A simple model is then developed for contraction and oscillation of a coronal loop. Results: We propose that coronal loop contractions and oscillations can occur in a single response to removal of magnetic energy from the corona. Our model reproduces the various types of loop motion observed and explains why the highest loops oscillate during their contraction while no oscillation is detected for the shortest contracting loops. The proposed framework suggests that loop motions can be used as a diagnostic for the removal of coronal magnetic energy by flares, while rapid decrease of coronal magnetic energy is a newly-identified excitation mechanism for transverse loop oscillations.

Abstract

Over the past 15 years, SCT has emerged as a promising treatment option for patients with severe autoimmune diseases (ADs). Mechanistic studies recently provided the proof-of-concept that restoration of immunological tolerance can be achieved by haematopoietic SCT in chronic autoimmunity through eradication of the pathologic, immunologic memory and profound reconfiguration of the immune system, that is, immune ‘resetting’. Nevertheless, a number of areas remain unresolved and warrant further investigation to refine our understanding of the underlying mechanisms of action and to optimize clinical SCT protocols. Due to the low number of patients transplanted in each centre, it is essential to adequately collect and analyse biological samples in a larger cohort of patients under standardized conditions. The European society for blood and marrow transplantation Autoimmune Diseases and Immunobiology Working Parties have, therefore, undertaken a joint initiative to develop and implement guidelines for ‘good laboratory practice’ in relation to procurement, processing, storage and analysis of biological specimens for immune reconstitution studies in AD patients before, during and after SCT. The aim of this document is to provide practical recommendations for biobanking of samples and laboratory immune monitoring in patients with ADs undergoing SCT, both for routine supportive care purposes and investigational studies.

Critical Infrastructures
Abstract

In the last few years we have witnessed a strong interest in the protection of Critical Infrastructures (CIs) such as power distribution networks, power plants, refineries, water distribution, transportation systems, hospitals or telecommunication networks. Despite their relevance for public safety and security, these infrastructures are highly exposed to a large number of threats, including natural hazards, component failure, criminal threats and terrorism. Several research projects address this topic. Many of them focus on building CI simulators for preventive analysis of system vulnerabilities, while others try to proactively strengthen partial sections of the CIs (such as fault tolerant components or secure control networks). Nevertheless, despite their positive results, those projects seldom provide mechanisms to assess, in real time, the risk level associated with each of the services provided by the addressed CI. Moreover, they do not take into account the high level of interdependency between heterogeneous CIs (power distribution failures, for instance, have a direct impact on telecommunication networks, which also affect other critical infrastructures and so on) or, when they do, they have to make compromises at the level of scalability, performance of the privacy of sensitive information. In this paper we present a CI alerting system that takes a step further, when compared to those approaches, by estimating in real time the risk level associated with each service provided by the CI (i.e. the current likelihood of service degradation or service shutdown induced on a given CI by undesired events occurred in that CI and/or other interdependent CIs).

Abstract

The interrelation of hard X-ray (HXR) emitting sources and the underlying physics of electron acceleration and transport presents one of the major questions in high-energy solar flare physics. Spatially resolved observations of solar flares often demonstrate the presence of well-separated sources of bremsstrahlung emission, so-called coronal and footpoint sources. Using spatially resolved X-ray observations by the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) and recently improved imaging techniques, we investigate in detail the spatially resolved electron distributions in a few well-observed solar flares. The selected flares can be interpreted as having a standard geometry with chromospheric HXR footpoint sources related to thick-target X-ray emission and the coronal sources characterised by a combination of thermal and thin-target bremsstrahlung. Using imaging spectroscopy techniques, we deduce the characteristic electron rates and spectral indices required to explain the coronal and footpoint X-ray sources. We found that, during the impulsive phase, the electron rate at the looptop is several times (a factor of 1.7-8) higher than at the footpoints. The results suggest that a sufficient number of electrons accelerated in the looptop explain the precipitation into the footpoints and imply that electrons accumulate in the looptop. We discuss these results in terms of magnetic trapping, pitch-angle scattering, and injection properties. Our conclusion is that the accelerated electrons must be subject to magnetic trapping and/or pitch-angle scattering, keeping a fraction of the population trapped inside the coronal loops. These findings put strong constraints on the particle transport in the coronal source and provide quantitative limits on deka-keV electron trapping/scattering in the coronal source., 12 pages, 7 figures

Abstract

O presente artigo objetivou apresentar os procedimentos metodológicos e as técnicas de geoprocessamento utilizadas para a extração de dados de bases cartográficas temáticas e de modelos hídricos espacializados requeridos para o cálculo de indicadores de sustentabilidade hídrica da cultura canavieira em quatro Microrregiões do Estado de Goiás: Sudoeste de Goiás, Vale do Rio dos Bois, Quirinópolis e Meia Ponte. Os diversos dados espaciais em formato shape, adquiridos de fontes secundárias e de modelos especificamente elaborados para este fim foram introduzidos em um Sistema de Informações Geográficas (SIG), no qual, por meio de técnicas simples de geoprocessamento, foram ajustados e integrados para a obtenção dos dados (grandezas físicas) utilizados para a determinação de indicadores (índices) propostos pelo Sistema de Indicadores para a Avaliação do Potencial de Sustentabilidade Hídrica da Atividade Canavieira - SISH-Cana (FERRAZ, 2012). Os resultados demonstram a pertinência das técnicas utilizadas e do nível de precisão e detalhamento dos modelos espaciais adotados, considerando que os índices aplicam-se para a avaliação de unidades territoriais de analise em nível de microrregião com vistas a planejamentos territoriais e/ou setoriais em nível estratégico.

Abstract

This study explored the suitability of the Normalized Difference Vegetation Index (NDVI) from the Moderate Resolution Imaging Spectrometer (MODIS) obtained for six sugar management zones, over nine years (2002?2010), to forecast sugarcane yield on an annual and zonal base. To take into account the characteristics of the sugarcane crop management (15-month cycle for a ratoon, accompanied with continuous harvest in Western Kenya), the temporal series of NDVI was normalized through an original weighting method that considered the growth period of the sugarcane crop (wNDVI), and correlated it with historical yield datasets. Results when using wNDVI were consistent with historical yield and significant at P-value = 0.001, while results when using traditional annual NDVI integrated over the calendar year were not significant. This correlation between yield and wNDVI is mainly drawn by the spatial dimension of the data set (R2 = 0.53, when all years are aggregated together), rather than by the temporal dimension of the data set (R2 = 0.1, when all zones are aggregated). A test on 2012 yield estimation with this model realized a RMSE less than 5 t·ha?1. Despite progress in the methodology through the weighted NDVI, and an extensive spatio-temporal analysis, this paper shows the difficulty in forecasting sugarcane yield on an annual base using current satellite low-resolution data. This is particularly true in the context of small scale farmers with fields measuring less than the size of MODIS 250 m pixel, and in the context of a 15-month crop cycle with no seasonal cropping calendar. Future satellite missions should permit monitoring of sugarcane yields using image resolutions that facilitate extraction of crop phenology from a group of individual plots.

Abstract

This paper illustrates the activities under development within the FP7 EU MICIE project. The project is devoted to design and implement an on-line alerting system, able to evaluate, in real time, the level of risk of interdependent Critical Infrastructures (CIs). Such a risk is generated by undesired events and by the high level of interconnection of the different infrastructures. Heterogeneous models are under development to perform short term predictions of the Quality of Service (QoS) of each CI according to the QoS of the others, to the level of interdependency among the Infrastructures, and according to the undesired events identified in the reference scenario.

Abstract

In this demonstration we present the MICIE platform for on-line risk assessment in scenarios with heterogeneous interdependent Critical Infrastructures (CIs) such as power distribution networks, power plants, refineries, water distribution networks, transportation systems and telecommunication networks. These CIs are highly exposed to a large number of threats, including natural hazards, component failures and intentional attacks. Moreover, the increasing interdependence between CIs amplifies the effects of such threats and adds novel challenges to risk assessment tools. In this context, MICIE is the first systematic approach to integrate CI interdependence factors in on-line risk assessment, addressing both the development of on-line risk assessment models and the development of an information sharing platform for continuous exchange of relevant risk information between interdependent CIs.

Abstract

A expansão da cultura da soja no sul da Amazonia Brasileira na decada de 1990 permitiu a emergência de novos territórios integrados a “economia mundial” depois da fase pioneira das décadas de 1970 e 1980. Mas, a queda dos preços, a “ferrugem asiática” (doença da soja), a variabilidade climática e as tensões ambientais levaram o setor agrícola a uma crise profunda entre 2004 e 2007. Esta crise demonstrou os limites deste modelo de desenvolvimento bem ilustrado pelo município de Sorriso (maior produtor de soja do Brasil). Os produtores procuram agora aproveitar as lições aprendidas a partir dos fracassos do passado e adaptar-se as novas normas impostas pela sociedade civil e os mercados internacionais (certificação ambiental, aplicação do código florestal, dentre outros). Vários esforços estão sendo realizados para intensificar e diversificar as produções, principalmente através da cultura do milho e do algodão. Enfim, projetos locais de desenvolvimento sustentável baseados na educação ambiental e sensibilização ao reflorestamento estão sendo criados. Isto comprova a vontade de parte dos atores locais de mudar o padrão de desenvolvimento da região.After the pioneer phase that occurred during the 1970's and 1980's, the expansion of mechanized agriculture (especially soybean crops) in the Southern part of the Brazilian Amazon basin led to the emergence of new territories integrated in " the world economy". However, low prices, the "Asian rust" (soybean's disease), the climatic variability and the environmental tensions pulled the agricultural sector in a deep crisis between 2004 and 2007. This crisis highlighted the limits of this model of development, well illustrated by the county of Sorriso (first soybean's producing county in Brazil). The producers are now learning from past failures in order to adapt themselves to the new standards imposed by the civil society and the international markets (environmental certification, forest code application, to mention some). Numerous efforts for the intensification and diversification of productions, especially by corn and cotton crops, were done. Furthermore, local sustainability projects based on environmental education and incentives to replantation are being developed. They illustrate the desire of part of the local actors to change the regional way of development., L'expansion de la culture du soja au sud de l'Amazonie brésilienne dans les années 1990 a permis l'émergence de nouveaux territoires intégrés à « l'économie monde » après la phase pionnière des décennies 1970 et 1980. Cependant, la baisse des cours, la « rouille asiatique » (maladie du soja), la variabilité climatique et les tensions environnementales ont entraîné la filière agricole dans une crise profonde entre 2004 et 2007. Cette crise a alors mis en exergue les limites de ce modèle de développement, bien illustré par la commune de Sorriso (première commune productrice de soja du Brésil). Les producteurs cherchent à présent à tirer les leçons des échecs du passé et à s'adapter aux nouvelles normes imposées par la société civile et les marchés internationaux (certification environnementale, application du code forestier,...). De nombreux efforts pour l'intensification et la diversification des productions notamment par le maïs et le coton sont réalisés. De plus, des projets locaux de développement durable axés sur l'éducation environnementale et l'incitation au reboisement voient le jour et témoignent également de la volonté d'une partie des acteurs locaux de changer le mode de développement de la région.
