Micro-récupération d'énergie des écoulements d'air par conversion électrostatique

Ce travail de these s’inscrit dans la grande problematique de la recuperation d’energie. Il s’agit plus precisement de convertir de petites quantites d’energie cinetique presentes dans un ecoulement d’air en energie electrique par l’intermediaire d’un convertisseur electrostatique. L’energie electrique convertie est ensuite destinee a alimenter des capteurs autonomes communicants pour le monitoring de structures, le suivi environnemental, le monitoring de sante…Le manuscrit comprend une etude des travaux anterieurs en recuperation d’energie des ecoulements d’air, la comprehension physique des phenomenes de conversion electrostatique, de mecanique des fluides et d’aerodynamique a tres faibles nombres de Reynolds, ainsi qu’une description des prototypes developpes et des resultats experimentaux obtenus.Les recuperateurs que nous avons developpes se divisent en deux grandes categories : (i) les recuperateurs rotatifs qui transforment l’energie cinetique de l’air en energie mecanique de rotation et (ii) les recuperateurs aeroelastiques qui puisent l’energie cinetique du vent pour produire de l’energie mecanique par oscillations periodiques. Ces deux types de recuperateurs ont ete associes a des convertisseurs electrostatiques dedies, polarises par l’ajout d’electrets ou auto-polarises par triboelectricite. Les recuperateurs d'energie ont ete optimises et nous avons notamment montre l'interet de la conversion electrostatique pour des dispositifs de petites dimensions (quelques cm²) fonctionnant a faible vitesse (<3m/s). Les densites surfaciques de puissance atteignent 5µW/cm2@1m/s pour les recuperateurs rotatifs et de l'ordre de 10µW/cm2@10m/s pour les recuperateurs aeroelastiques. Les micro-generateurs ont finalement ete combines a des circuits de gestion d'energie pour alimenter des capteurs autonomes communicants, validant la chaine complete de recuperation d'energie, montrant par la meme occasion l'interet des circuits de gestion d'energie actifs de type SECE (synchronous electric charge extraction) ou MPP (maximum power point).
An overview of cancer immunotherapy

The survival of patients with cancer has improved steadily but incrementally over the last century, with the advent of effective anticancer treatments such as chemotherapy and radiotherapy. However, the majority of patients with metastatic disease will not be cured by these measures and will eventually die of their disease. New and more effective methods of treating these patients are required urgently. The immune system is a potent force for rejecting transplanted organs or microbial pathogens, but effective spontaneous immunologically induced cancer remissions are very rare. In recent years, much has been discovered about the mechanisms by which the immune system recognizes and responds to cancers. The specific antigens involved have now been defined in many cases. Improved adjuvants are available. Means by which cancer cells overcome immunological attack can be exploited and overcome. Most importantly, the immunological control mechanisms responsible for initiating and maintaining an effective immune response are now much better understood. It is now possible to manipulate immunological effector cells or antigen‐presenting cells ex vivo in order to induce an effective antitumour response. At the same time, it is possible to recruit other aspects of the immune system, both specific (e.g. antibody responses) and innate (natural killer cells and granulocytes).
Design of narrowband microwave filters with mixed-topology

Narrow band microwave filters exhibiting transmission zeros in the response (either imaginary and/or complex) can be typically designed with cross-coupled or extracted pole topologies. These configurations present pro & cons which must be carefully considered during the choice of a specific topology. In some cases it could be however very convenient the choice of a mixed topology, i.e. part of the structure with extracted-pole and part with cross-coupled configuration. Unfortunately, even if several well established techniques are available in the literature for the cross-coupled or extracted-pole synthesis taken separately, nothing can be found for the design of mixed-topology filters (apart direct optimization)
Preclinical Lipid profile studies of a classical Ayurvedic preparation "Kutajarista" after chronic administration to male Sprague-Dawley rats

Kutajarista (KTJ) is an Ayurvedic preparation used as a traditional medicine in the South Asian countries for the treatment of diarrhoea, dysentery and irritable bowel syndrome. The effect of chronic administration of KTJ on the serum lipid profile was studied in this experiment. After 28 days of chronic administration of the KTJ preparation to the male Sprague-Dawley rats at a dose of 40 ml/kg the following biochemical changes were noted. There was a statistically very highly significant (p=0.001) increase in serum LDL-C level whereas a significant increase was noted in case of total cholesterol (TC) level (p=0.013). A significant (p=0.039) decrease was noticed in HDL-C level but in case of Non-HDL-C level, a highly significant (p=0.002) increase was noticed. Besides, a statistically very highly significant (p=0.001) decrease was noted in case of serum triglyceride (TG) and VLDL-C level; thus leading to a statistically highly significant increase (p=0.004) in Cardiac Risk Ratio (CRR) (TC/HDL-C) and Atherogenic Coefficient (AC) ((TC -HDL-C)/HDL-C), a statistically very highly significant (p=0.001) increase in Castelli's Risk Index-II (CRI- II) (LDL-C/HDL-C) but a statistically very highly significant decrease (p=0.001) in case of Atherogenic Index of Plasma (AIP) ((log
Evidence of a shift in the cyclicity of Antarctic seabird dynamics linked to climate

Ecosystems and populations are known to be influenced not only by long-term climatic trends, but also by other short-term climatic modes, such as interannual and decadal-scale variabilities. Because interactions between climatic forcing, biotic and abiotic components of ecosystems are subtle and complex, analysis of long-term series of both biological and physical factors is essential to understanding these interactions. Here, we apply a wavelet analysis simultaneously to long-term datasets on the environment and on the populations and breeding success of three Antarctic seabirds (southern fulmar, snow petrel, emperor penguin) breeding in Terre Adélie, to study the effects of climate fluctuations on Antarctic marine ecosystems. We show that over the past 40 years, populations and demographic parameters of the three species fluctuate with a periodicity of 3–5 years that was also detected in sea-ice extent and the Southern Oscillation Index. Although the major periodicity of these interannual fluctuations is not common to different species and environmental variables, their cyclic characteristics reveal a significant change since 1980. Moreover, sliding-correlation analysis highlighted the relationships between environmental variables and the demography of the three species, with important change of correlation occurring between the end of the 1970s and the beginning of the 1980s. These results suggest that a regime shift has probably occurred during this period, significantly affecting the Antarctic ecosystem, but with contrasted effects on the three species.
Paris Agreement on Climate Change: A Booster to Enable Sustainable Global Development and Beyond

The global warming and its adverse effects on the atmosphere, the biosphere, the lithosphere, and the hydrosphere are obvious. Based on this fact, the international community is fully convinced that we need to fix the problem urgently for our survival, good health, and wellbeing. The aim of this article is to promote the awareness about the United Nations (UN) historic ‘Paris Agreement on Climate Change (PACC)’ which entered into-force on 4 November 2016. The expected impact of PACC on the global average temperature rise by 2100 as well as its role in enabling accomplishment of global sustainable development goals (SDGs) for the people and planet is also highlighted.

Indoor localization in home environments using appearance frequency information

Recognizing the location of an individual in a home environment is crucial in order to enable various context-aware home applications such as elderly health monitoring and in home appliance automation. However, due to the limited number of dedicated Wi-Fi access points (APs), it is challenging to guarantee the reliable localization performance in a home environment by using the traditional Wi-Fi fingerprinting (WF) technique. In this paper, we propose a room-level localization system for the typical residential home environments which comprise of a living room, a kitchen, a bathroom, and a bedroom. Specifically, we make use of appearance frequency (AF) information of APs at each location in order to narrow down the number of candidate locations before performing the Wi-Fi Fingerprinting scheme. Our system improves the localization performance by up to 17.5 % (11.29 % on average) over that of the traditional WF-based approach which does not exploit AF information. We achieved the room-level positioning accuracy of 84.76% on the dataset of 6 home environments.
17-β-Estradiol-Dependent Regulation of Somatostatin Receptor Subtype Expression in the 7315b Prolactin Secreting Rat Pituitary Tumor in Vitro and in Vivo.

In the present study, we have investigated the role of estrogens in the regulation of somatostatin receptor subtype (sst) expression in 7315b PRL-secreting rat pituitary tumor cells in vitro and in vivo. sst were undetectable in freshly dispersed cells of the transplantable 7315b tumor. When 7315b cells were cultured in medium containing 10% FCS, the number of high affinity sst increased with prolonged culture time. However, when the medium was supplemented with 10% horse serum (HS) instead of FCS, no sst were detectable on 7315b cells even after three weeks of culturing. In contrast to HS, FCS contains high E2-levels (HS, 8 pm; FCS, 134 pm). The antiestrogen tamoxifen (0.5 μm) significantly inhibited the sst number to 50.5% of the value of untreated FCS-grown cells, suggesting that E2 stimulates sst expression in 7315b rat pituitary tumor cells. E2 (10 nm) induced a rapid increase in sst number in HS-grown 7315b cells. Octreotide (1 μm) significantly inhibited PRL release and the intracellular PRL concen.
Building a Conceptual Graph Bank for Chinese Language

In this paper, we introduce a new semantic resource, i.e., conceptual graph bank, for Chinese language. The resource is to provide conceptual information for each sample sentence, which includes concepts, conceptual relationship, head, and conceptual hierarchies. Compared with treebanks, the resource focuses on static semantic information. We also introduce recursive graph to denote the conceptual information.
Lower risk of stent thrombosis and restenosis with unrestricted use of 'new-generation' drug-eluting stents: a report from the nationwide Swedish Coronary Angiography and Angioplasty Registry (SCAAR).

AIMS To compare the long-term outcome after percutaneous coronary intervention with 'new-generation' drug-eluting stents (n-DES) to 'older generation' DES (o-DES), and bare-metal stents (BMS) in a real-world population. METHODS AND RESULTS We evaluated 94 384 consecutive stent implantations (BMS, n = 64 631; o-DES, n = 19 202; n-DES, n = 10 551) in Sweden from November 2006 to October 2010. All cases of definite stent thrombosis (ST) and restenosis were documented in the Swedish Coronary Angiography and Angioplasty Registry (SCAAR). Older generation DES were classified as: Cypher and Cypher Select (Cordis Corporation, Miami, FL, USA), Taxus Express and Taxus Liberté (Boston Scientific Corporation), and Endeavor (Medtronic Inc.) and n-DES as: Endeavor Resolute (Medtronic Inc.), XienceV, Xience Prime (Abbott Laboratories) and Promus, Promus Element (Boston Scientific Corporation). The Cox regression analyses unadjusted and adjusted for clinical and angiographic covariates showed a statistically significant lower risk of restenosis in n-DES compared with BMS [adjusted hazard ratio (HR) 0.29; 95% confidence interval (CI): 0.25-0.33] and o-DES (HR 0.62; 95% CI: 0.53-0.72). A lower risk of definite ST was found in n-DES compared with BMS (HR 0.38; 95% CI: 0.28-0.52) and o-DES (HR, 0.57; 95% CI: 0.41-0.79). The risk of death was significantly lower in n-DES compared with o-DES (adjusted HR: 0.77; 95% CI: 0.63-0.95) and BMS (adjusted HR: 0.55; 95% CI: 0.46-0.67). CONCLUSION Percutaneous coronary intervention with n-DES is associated with a 38% lower risk of clinically meaningful restenosis, a 43% lower risk of definite ST, and a 23% lower risk of death compared with o-DES in this observational study from a large real-world population.
Phytochromes function as thermosensors in Arabidopsis

Combining heat and light responses Plants integrate a variety of environmental signals to regulate growth patterns. Legris et al. and Jung et al. analyzed how the quality of light is interpreted through ambient temperature to regulate transcription and growth (see the Perspective by Halliday and Davis). The phytochromes responsible for reading the ratio of red to far-red light were also responsive to the small shifts in temperature that occur when dusk falls or when shade from neighboring plants cools the soil. Science, this issue p. 897, p. 886; see also p. 832 Red-light photoreceptors also act as temperature sensors in plants. Plants are responsive to temperature, and some species can distinguish differences of 1°C. In Arabidopsis, warmer temperature accelerates flowering and increases elongation growth (thermomorphogenesis). However, the mechanisms of temperature perception are largely unknown. We describe a major thermosensory role for the phytochromes (red light receptors) during the night. Phytochrome null plants display a constitutive warm-temperature response, and consistent with this, we show in this background that the warm-temperature transcriptome becomes derepressed at low temperatures. We found that phytochrome B (phyB) directly associates with the promoters of key target genes in a temperature-dependent manner. The rate of phyB inactivation is proportional to temperature in the dark, enabling phytochromes to function as thermal timers that integrate temperature information over the course of the night.
Siberian Peatlands a Net Carbon Sink and Global Methane Source Since the Early Holocene

Interpolar methane gradient (IPG) data from ice cores suggest the “switching on” of a major Northern Hemisphere methane source in the early Holocene. Extensive data from Russia's West Siberian Lowland show (i) explosive, widespread peatland establishment between 11.5 and 9 thousand years ago, predating comparable development in North America and synchronous with increased atmospheric methane concentrations and IPGs, (ii) larger carbon stocks than previously thought (70.2 Petagrams, up to ∼26% of all terrestrial carbon accumulated since the Last Glacial Maximum), and (iii) little evidence for catastrophic oxidation, suggesting the region represents a long-term carbon dioxide sink and global methane source since the early Holocene.
Methods to Enhance the Performance of InGaAs/InP Heterojunction Tunnel FETs

This paper presents a simulation study of In0.53Ga0. 47As/InP heterojunction gate-overlapped-source tunnel FETs (GoS-TFETs) with pocket counter-doping. The effect of channel quantization on the line tunneling is considered in the semiclassical simulations using a new model that modifies the band edge in the inversion layer. The small bandgap of the source material In0.53Ga0. 47As results in an improved tunnel rate, while the wide bandgap of the channel/drain material InP reduces ambipolar leakage. The simulations show that, for the case of perfectly aligned p-n-junction and heterojunction, the type-I band alignment and the large band offsets delay suppress lateral (point) tunneling relative to vertical (line) tunneling which improves the subthreshold swing (SS). The counter-doped pocket in the source region advances the onset of line tunneling relative to point tunneling which also assists in mitigating the effects of point tunneling. In this way, both large band offset and counter-doped pocket improve the subthreshold behavior of the TFET. Placing the p-n-junction inside the InP region makes the vertical tunneling even more dominant and, thus, reduces the SS. The suggested modifications might be useful to improve the device performance beyond that of the conventional GoS-TFETs.
The Fire Modeling Intercomparison Project (FireMIP), phase 1: Experimental and analytical protocols with detailed model descriptions

The important role of fire in regulating vegetation community composition and contributions to emissions of greenhouse gases and aerosols make it a critical component of dynamic global vegetation models and Earth system models. Over 2 decades of development, a wide variety of model structures and mechanisms have been designed and incorporated into global fire models, which have been linked to different vegetation models. However, there has not yet been a systematic examination of how these different strategies contribute to model performance. Here we describe the structure of the first phase of the Fire Model Intercomparison Project (FireMIP), which for the first time seeks to systematically compare a number of models. By combining a standardized set of input data and model experiments with a rigorous comparison of model outputs to each other and to observations, we will improve the understanding of what drives vegetation fire, how it can best be simulated, and what new or improved observational data could allow better constraints on model behavior. In this paper, we introduce the fire models used in the first phase of FireMIP, the simulation protocols applied, and the benchmarking system used to evaluate the models. We have also created supplementary tables that describe, in thorough mathematical detail, the structure of each model.

Una nueva técnica para evaluar sistemas conversacionales basada en la generación automática de diálogos

En este articulo se presenta una nueva tecnica que permite evaluar sistemas conversacionales mediante la simulacion de las interacciones que realizan los usuarios de los mismos. Creemos que la tecnica puede ser util para conocer aspectos de los sistemas conversacionales que se deben mejorar antes de que se encuentren operativos en condiciones reales. Utilizando esta tecnica, se ha evaluado el funcionamiento de un sistema conversacional desarrollado en nuestro laboratorio, el cual se encuentra en fase experimental actualmente. La evaluacion se ha realizado considerando diversas condiciones de ruido. Los resultados obtenidos muestran que el uso de una tecnica de compensacion de ruido mejora el funcionamiento del sistema. La tecnica propuesta ha permitido detectar errores de la estrategia utilizada por el sistema para procesar las confirmaciones de los usuarios.
LOW INTRASPECIFIC VARIATION FOR GENOMIC ISOLATION BETWEEN HYBRIDIZING SUNFLOWER SPECIES

Abstract Barriers to gene flow between species result from selection against foreign linkage blocks in hybrids. When the geographic ranges of taxa meet at multiple locations, the opportunity exists for variation in the genetic architecture of isolating barriers. Hybrid zones between two sunflower species (Helianthus annuus and H. petiolaris) in Nebraska and California exhibited remarkably similar patterns of introgression of mapped molecular markers. Congruence among hybrid zones may result from limited intraspecific variation at loci contributing to isolation and from similar selective effects of alleles in the heterospecific genetic background. The observed consistency of introgression patterns across distantly separated hybrid zones suggests that intrinsic forces predominate in determining hybrid zone dynamics and boundaries between these sunflower species.

The Eternal return: analysis of the temporal conception in the Dark series of Netflix

El presente trabajo analiza la conceptualizacion del tiempo tratada en la serie para television Dark (Daran bo Odar y Jantje Friese, 2017), transmitida por la plataforma digital Netflix. El argumento presenta la concepcion del tiempo como algo ciclico, fundamentada en la idea del eterno retorno, recogida por Friedrich Nietzsche en sus obras La gaya ciencia (1882) y Asi hablo Zaratustra (1883). A diferencia de la idea filosofica, Dark plantea la posibilidad real del funcionamiento del tiempo como un bucle eterno, lo cual produce la eliminacion de las concepciones clasicas de pasado, presente y futuro, debido a que los personajes pueden moverse entre estos tiempos e influir sobre los hechos que suceden antes o despues. A traves de los capitulos la serie fundamenta esta idea, se apoya en elementos de la ciencia ficcion como los viajes en el tiempo, los agujeros de gusano y las invenciones humanas orientadas a cambiar y alterar el curso de los hechos en una sola linea temporal para demostrar como las acciones de una persona en diferentes estados configuran la realidad en la que vivimos.
Pump interactions in a 100-nm bandwidth Raman amplifier

A design for a 100-nm bandwidth Raman amplifier is presented. The amplifier is pumped with eight, 130-mW lasers with wavelengths ranging from 1416 to 1502 nm. The peak-to-peak gain ripple is 1.1 dB. A new model was developed for this design that includes pump-to-pump and signal-to-signal interactions in addition to double Rayleigh scattering and amplified spontaneous emission. An understanding of the interactions among these various effects was essential to this design. These modeling results are based on measurements of the physical characteristics of the transmission fiber.
