description: Le CAR (Crustacean Algae Replacement) se substitue totalement aux algues pour un dosage et une fréquence de distribution déterminés. Les résultats de survie à Zoé3 restent malgré tout variables. La raison essentielle semble être la qualité bactériologique de l'eau de mer. Les artémias peuvent être remplacés à 50% par du CD3 (Crustacean Diet), ce taux de substitution offre le meilleur compromis survie et qualité des PL.

description: Ultracold atoms trapped in laser-generated optical lattices serve as a versatile platform for quantum simulations. However, as these lattices are infinitely stiff, they do not allow to emulate phonon degrees of freedom. This restriction can be lifted in emerged optical lattices inside multimode cavities. Motivated by recent experimental progress in multimode cavity QED, we propose a scheme to implement and study supersolid and droplet states with phonon-like lattice excitations by coupling a Bose gas to many longitudinal modes of a ring cavity. The interplay between contact collisional and tunable-range cavity-mediated interactions leads to a rich phase diagram, which includes elastic supersolid as well as insulating droplet phases exhibiting roton-type mode softening for a continuous range of momenta across the superradiant phase transition. The non-trivial dynamic response of the system to local density perturbations further proves the existence of phonon-like modes.

description: Cette étude financée par le Ministère de l’Outre-Mer est une collaboration de l’Ifremer avec l’Université de Polynésie Française et l’Institut Louis Malardé. Cette étude a permis l’acquisition de connaissances nouvelles sur la nutrition de l’huître perlière Pinctada margaritifera dans le milieu naturel, et ainsi, de mieux envisager les besoins nutritionnels pendant la reproduction. Les besoins en lipides, acides gras et stérols, ont été spécifiquement étudiés.
La composition en acides gras neutres et polaires des gonades femelles ne subit pas de variations significatives au cours de l’ovogenèse. En revanche, la composition des oeufs après la ponte subit des modifications significatives au sein des lipides neutres et polaires. Cependant ces modifications concernent très peu d’acides gras : 3 acides gras neutres et 6 acides gras polaires. Les teneurs en stérols reflètent particulièrement bien l’évolution de l’ovogenèse et cet effet se traduit particulièrement au niveau du cholestérol et du rapport ester de stérols/stérols totaux.
Cette étude fait apparaître des différences spatio-temporelles dans la composition lipidique des oeufs. En effet, les oeufs obtenus à Vairao et ceux obtenus à Rangiroa ont des différences significatives de la teneur en acides gras neutres et polaires et au sein des stérols. Ces différences résultent probablement de la différence de composition des particules alimentaires filtrées par les huîtres propres à chaque lagon.
Les souches d’algues cultivées en laboratoire au Centre Océanologique du Pacifique ont été analysées pour leur contenu en acides gras et stérols afin d’être en mesure d’élaborer le régime alimentaire, un cocktail d’algues, permettant de fournir les éléments essentiels en terme d’acides gras essentiels et de stérols détectés dans les gonades des huîtres femelles et les oeufs.

description: We study the extent of the spin liquid phases in the Kitaev-Heisenberg model using infinite Projected Entangled-Pair States tensor network ansatz wave functions directly in the thermodynamic limit. To assess the accuracy of the ansatz wave functions we perform benchmarks against exact results for the Kitaev model and find very good agreement for various observables. In the case of the Kitaev-Heisenberg model we confirm the existence of 6 different phases: Néel, stripy, ferromagnetic, zigzag and two spin liquid phases. We find finite extents for both spin liquid phases and discontinuous phase transitions connecting them to symmetry-broken phases.

description: Congestion controls that focus on achieving a low queuing delay, such as the novel TCP LoLa, can significantly improve the quality-of-experience for delay-sensitive applications. The gradual deployment of such congestion controls, however, is challenging because their data flows get suppressed by flows that use a legacy loss-based congestion control (e.g. CUBIC TCP). This demo shows the advantages of TCP LoLa for interactive applications at the example of a network-enabled version of the well-known PONG game. In addition to that, the demo shows how SDN technology can be used to facilitate the coexistence between low delay and loss-based congestion controls.

description: We present generalization of the Bloom variety theorem of ordered algebras in fuzzy setting. We introduce algebras with fuzzy orders which consist of sets of functions which are compatible with particular binary fuzzy relations called fuzzy orders. Fuzzy orders are defined on universe sets of algebras using complete residuated lattices as structures of degrees. In this setting, we show that classes of models of fuzzy sets of inequalities are closed under suitably defined formations of subalgebras, homomorphic images, and direct products. Conversely, we prove that classes having these closure properties are definable by fuzzy sets of inequalities.

description: Dans le cadre du programme Reproduction de l’huître perlière Pinctada margaritifera, dont l’objectif est la maîtrise des croisements, le conditionnement en laboratoire des reproducteurs est une étape nécessaire pour espérer contrôler et synchroniser la maturation de ces reproducteurs. Les facteurs présumés qui permettront de contrôler la maturation sont d’ordre environnemental : l’alimentation et la température. Cependant avant d’espérer établir la relation entre la fonction physiologique et les facteurs qui contrôlent cette fonction, il est indispensable de mettre en œuvre une zootechnie adaptée aux besoins vitaux de façon à assurer la survie et une bonne croissance. Cette étude a pour objectif de tester la survie et la croissance des huîtres perlières dans une enceinte expérimentale que nous cherchons à valider. L’enceinte testée est un raceway où les conditions hydrodynamiques satisfont les besoins environnementaux des huîtres. L’expérience consiste à mettre en élevage pendant une période de 3 mois des huîtres de petite taille d’environ 5 cm de hauteur extérieure, à les alimenter avec des algues et à observer la croissance par une approche biométrique. Un échantillonnage hebdomadaire est fait pour déterminer la croissance coquillière et somatique. Le lot mis en élevage en laboratoire est comparé avec un autre lot de même origine placé dans le lagon.
Un autre aspect de l’objectif de cette étude qui est un préliminaire au Projet Conditionnement est d’obtenir des informations d’ordres statistiques sur la variabilité de la réponse. Les plans expérimentaux à venir seront conçus en fonction de la variabilité obtenue, permettant ainsi d’optimiser les cheptels en expérimentation.
Cette expérimentation a duré 3 mois. Les animaux ont été fournis par l’antenne du service de la perliculture de Takapoto. Pour des raisons pratiques, nous avons choisi de travailler avec des petites huîtres puisque la consommation alimentaire est moins importante que celles des grandes, et surtout pour la plus forte amplitude de croissance.

description: Particulate air pollution is taking a huge toll on modern society, being associated with more than three million deaths per year. In addition, airborne infectious microorganism can spread dangerous diseases, further elevating the problem. A common way to mitigate the risks of airborne particles is by air filtration. However, conventional air filters usually do not provide any functionality beyond particle removal. They are unable to inactivate accumulated contaminants and therefore need periodic maintenance and replacement to remain operational and safe. This work presents a multifunctional, self-cleaning air filtration system which utilizes a novel graphene-enhanced air filter medium (GeFM). The hybrid network of the GeFM combines the passive structure-based air filtration properties of an underlying ceramic network with additional active features based on the functional properties of a graphene thin film. The GeFM is able to capture >95 % of microorganisms and particles larger than 1 $μ$m and can be repetitively Joule-heated to >300 °C for several hours without signs of degradation. Hereby, built-up organic particulate matter and microbial contaminants are effectively decomposed, regenerating the GeFM. Additionally, the GeFM provides unique options to monitor the filter's air troughput and loading status during operation. The active features of the GeFM can drastically improve filter life-time and safety, offering great potential for the development of safer and more sustainable air filtration solutions to face the future challenges of air pollution and pandemics.

Connecting Star Formation Quenching with Galaxy Structure and Supermassive Black Holes through Gravitational Heating of Cooling Flows

Year: 2014
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

subject: FOS: Physical sciences

description: Recent observations suggested that star formation quenching in galaxies is related to galaxy structure. Here we propose a new mechanism to explain the physical origin of this correlation. We assume that while quiescent galaxies are maintained quenched by a feedback mechanism, cooling flows in the hot halo gas can still develop intermittently. We study cooling flows in a large suite of around 90 hydrodynamic simulations of an isolated galaxy group, and find that the flow development depends significantly on the gravitational potential well in the central galaxy. If the galaxy's gravity is not strong enough, cooling flows result in a central cooling catastrophe, supplying cold gas and feeding star formation to galactic bulges. When the bulge grows prominent enough, compressional heating starts to offset radiative cooling and maintains cooling flows in a long-term hot mode without producing cooling catastrophe. Our model thus describes a self-limited growth channel for galaxy bulges, and naturally explains the connection between quenching and bulge prominence. In particular, we explicitly demonstrate that $M_{*}/R_{\rm eff}^{1.5}$ is a good structural predictor of quenching. We further find that the gravity from the central supermassive black hole also affects the bimodal fate of cooling flows, and predict a more general quenching predictor to be $M_{\rm bh}^{1.6}M_{*}/R_{\rm eff}^{1.5}$, which may be tested in future observational studies.

description: Volume I of the PRE-COLUMBIAN BURIAL RITES series consists of a comprehensive examination and discussion of mortuary behaviors by the prehistoric inhabitants of the Southwest Region of North America. The study of burial practice is useful to the discussion of the complexities of population traits and characteristics because on a societal scale, similarity or differentiation of patterning in the disposal of the dead has been considered one of the basic identifying "signatures" used to distinguish cultural populations. Because burial of the dead is a ritually-oriented, ideologically-grounded rite of passage, its very nature is conservative, steeped in tradition and resistant to change. It is possible and vital, therefore, to identify repetitive characteristics of burial customs. For this purpose a mortuary sample of 17,587 burials from 385 mortuary sites was utilized to address the range of variability and consistency within the four subdivisions of the Southwest Region that includes the Hohokam, Mogollon, Ancestral Puebloan, and Northern Rio Grande populations.

description: Structural and dynamical behavior of SO$_2$ molecules within ZSM22 is studied using MD simulations, to understand the influence of orientational disorder (OD) and intercrystalline spacing in ZSM22 as a function of adsorbate loading. Addition of inter-crystalline space provides connectivity of isolated pores in ZSM22 and is shown to suppress both translational and rotational motion of SO$_2$. We infer that geometry and dimensionality of the connecting space is an important factor in determining the effects of pore connectivity on the adsorbed species behavior. As a function of OD, decrease in self diffusion coefficient of SO$_2$ in ZSM22 is observed. An increase in rotational correlation time t and a decrease in libration angle with OD is observed, due to the restriction imposed on the orientational freedom of the adsorbate by an increase in OD. The behavior of SO$_2$ result from an interplay of guest-host interactions and the dimensionality and confinement geometry.

description: Mortuary Practice Among Prehistoric North Americans: Plains Region, is Volume II of the five volume set entitled PRE-COLUMBIAN BURIAL RITES. Twelve years of research that covered North America between the Rockies and the Appalachians provided a comprehensive multi-regional database consisting of 97,821 deceased individuals from 3,678 prehistoric burial sites. From that database I formulated a Plains region database consisting of 13,104 deceased individuals from 1,229 burial sites within Montana, Wyoming, Colorado, North and South Dakota, Nebraska, Kansas, Oklahoma, and Texas. Built on the premise that analysis of mortuary practice is a valuable tool in the examination of prehistoric cultural entities, the variability and consistency of burial traits on the Plains establishes a pattern of conservative behaviors that are definitive in the detection of cohesive cultural groups. Burial traits that were thoroughly investigated included: MNI (minimum number of individuals), cremation, secondary inhumation, primary inhumation, bundling, position of deposition, placement, age and sex, artificial cranial flattening, time line, cultural affiliation, mortuary furniture specifics, head direction, mortuary facility, and in-site burial location. It was ascertained that multiple cultural populations exhibited ritually-oriented and conservatively-grounded patterns of behavior that differentiated their society's practice of burial ideology. The ritual patterns also indicated that over long spans of time, societal disruption occurred when cultures adapted to internally changing viewpoints, sometimes exacerbated by changing climate and geographic environments. Because the North American plains is a vast territory the detailed analysis of prehistoric burial characteristics was a complex and intricate web of sub-regional population movements through time that documented with some clarity how the different cultural groups dealt with the disposal of the deceased population on the prehistoric North American plains.

description: In this paper, we study the interaction between two two-level atoms and two coupled modes of a quantized radiation field in the form of parametric frequency converter injecting within an optical cavity enclosed by a medium with Kerr nonlinearity. It is demonstrated that, by applying the Bogoliubov-Valatin canonical transformation, the introduced model is reduced to a well-known form of the generalized Jaynes-Cummings model. Then, under particular initial conditions which may be prepared for the atoms (in a coherent superposition of its ground and upper states) and the fields (in a standard coherent state), the time evolution of state vector of the entire system is analytically evaluated. In order to understand the degree of entanglement between subsystems (atom-field and atom-atom), the dynamics of entanglement through different measures, namely, von Neumann reduced entropy, concurrence and negativity is evaluated. In each case, the effects of Kerr nonlinearity and detuning parameter on the above criteria are numerically analyzed, in detail. It is illustrated that the amount of the degree of entanglement can be tuned by choosing the evolved parameters, appropriately.

description: We develop a model for quantum computation with Rydberg atom arrays, which only relies on global driving, without the need of local addressing of the qubits: any circuit is executed by a sequence of global, resonant laser pulses on a static atomic arrangement. We present two constructions: for the first, the circuit is imprinted in the trap positions of the atoms and executed by the pulses; for the second, the atom arrangement is circuit-independent, and the algorithm is entirely encoded in the global driving sequence. Our results show in particular that a quadratic overhead in atom number is sufficient to eliminate the need for local control to realize a universal quantum processor. We give explicit protocols for all steps of an arbitrary quantum computation, and discuss strategies for error suppression specific to our model. Our scheme is based on dual-species processors with atoms subjected to Rydberg blockade constraints, but it might be transposed to other setups as well.

description: Laser-induced breakdown spectroscopy (LIBS) show enhancement in its signal, when the laser-induced plasma is confined/decelerated under the effect of an external steady magnetic field or in a small cavity. An enhancement in LIBS signal has been observed ~2 times in the case of magnetic confinement. Combination of magnetic and spatial confinement provide enhancement by an order of magnitude. Theoretical analysis of the decelerated plasma has been found in agreement with the experimental observations. The enhancement in LIBS signal is found dependent on the efficiency of plasma confinement as well as on the time duration of laser. The saturation in LIBS signal at higher laser intensity is found correlated with electron-ion collision frequency as well as on the dynamics and instability of plasma plume. Possibility of further enhancement in emission has also been discussed.

For twenty years, the survey takes place in July, best compromise between enough growing of the group 1 shells, faster in the Bay of Seine than in the Saint-Brieuc Bay, allowing their capture by sampling dredges, and early expertise which allows to stakeholders (administrative, market organization, professional committee, ...) to take the best measures suited to the reality perceived through the survey’s results. The results are presented in distinguishing the off-shore part of the Bay of Seine, located beyond the French territorial waters, and the classified Seine Bay, entirely located inside the territorial waters and subjected to highly regulation of fisheries.

In July 2012, the estimation of exploitable biomass is very high this year, and reach a historically record level. It is mainly composed of the 2 years old King scallops cohort, which arrive this year as recruitment in the fishery. These scallops’ size is under the medium decade size. The exploitable biomass is quite well distributed in both parts of the bay of Seine. The pre-recruitment (one year old scallops) is at a medium level.
description: Les campagnes d’évaluation du stock de coquilles Saint-Jacques Pecten maximus de la baie de Seine (COMOR) ont pour objectif principal d’établir un diagnostic annuel de l’état de la ressource (abondance par classes d’âge, croissance observée, répartition sur le fond) avant l’ouverture de la saison de pêche. Depuis une vingtaine d’années la campagne a lieu en juillet, meilleur compromis entre une pousse suffisante des coquilles du groupe 1, plus rapide en baie de Seine qu’en baie de St-Brieuc et permettant leur capture par les dragues, et l'élaboration précoce d'une expertise permettant aux acteurs (administratifs, organisation de marché, commission professionnelle, …) de prendre les mesures les mieux adaptées à la réalité perçue à travers les résultats de la campagne. Les résultats obtenus sont présentés en distinguant la partie extérieure de la baie de Seine, située au-delà des eaux territoriales françaises, du gisement classé de la baie de Seine, entièrement situé dans les eaux territoriales, et soumis à une réglementation des pêches plus stricte.

En juillet 2012, la biomasse exploitable estimée est exceptionnelle et atteint un niveau jamais approché historiquement, tant dans la partie Extérieur baie de Seine que dans le gisement classé. Cette biomasse exceptionnelle correspond à l’arrivée dans la pêcherie de la cohorte 2010. Les coquilles de cette classe d’âge sont par contre de petite taille. La biomasse exploitable est de plus répartie sur le fond de façon relativement homogène sur toutes les zones. Le pré-recrutement (coquilles de 1 an) est moyen.

description: Genital herpes caused by herpes simplex virus (HSV) infection is one of the most prevalent sexually transmitted infections (STIs) and the most common cause of genital ulcer disease (GUD) in developed and developing countries. The monitoring of HSV‐2 seroprevalence in pregnant women can identify women at a higher risk of HIV and of neonatal HSV transmission. Very few data are available on type specific seroprevalence of HSV‐2 in China, with only one previous study from southern China. Consequently, we conducted a survey to determine type specific seroprevalence of HSV‐2 and associated risk factors in Fuzhou City, eastern China.

description: 209Bi nuclear magnetic resonance (NMR) spectroscopy was employed to probe potential spin-orbit effects on orbital diamagnetism in YPtBi and YPdBi crystals. The observed opposite sign and temperature dependent magnitude of 209Bi NMR shifts of both crystals reveal experimental signatures of enhanced orbital diamagnetism induced by spin-orbit interactions. This investigation indicates that NMR isotropic shifts might be beneficial in search of interesting spin-electronic phases among a vast number of topological nontrivial half-Heusler semimetals.

description: In the last years, the use of robotics technology in agriculture is constantly increasing. Robotic platforms are the application of automation and robotics in agriculture field to relieve manual and heavy tasks from workers. These devices have already started to transform many aspects of agriculture and are hesitantly finding their way to the market. Therefore, robotic solutions which can provide alternative routes to weed management may provide a transformational enabling technology to mitigate against biotic and abiotic stresses on crop production, for example automatic weeding robots are the preferable substitute for chemical herbicide to remove weeds. One of the most impacting abiotic factors in agriculture are weeds, causing important yield loss in every cultivation. Integrated weed management coupled with the use of robotic platforms (UGVs), allows the effectively weed management, us a beneficial methodology for the environment. The detection of weed spots in a cultivation can be achieved by combining image acquisition by UGV and further processing by specific algorithms. These algorithms can be used to weeds control by autonomous robotic systems via mechanical procedures or herbicide spray.
 The weed management is one of the major challenges in viticulture, as long as weeds can cause significant yield losses and severe competition to vines. One of the cheapest and effectiveness method remains the weed control with chemicals; however, several adverse effects and risks may arise. Different methods like tillage, thermal method, mulching and cover crops can be included in weed control strategy, depending on the environmental conditions, soil and crop. As it is known, the mechanical methods are the most cost-effective weed management methods in vineyards.
 Monitoring weed in different vineyards will provide a useful database for understanding the weed management practices. In this direction, this paper presents a system for a weeding detection robot. The objective is to be enabling the weed detection robot to navigate autonomously between the inter-row spaces of crop for automatic weed control, reduce labor cost and time. In this paper, various of image processing techniques with the implementation of an RGB-D camera was examined in order to: i) detect the path between two rows of vineyard and ii) allocate the weeds based on various a priori characteristics. As a pre-processing state, the real time data from the RGB-D camera transformed into different color spaces in order to denote the noise that could occur. Subsequently, the examined algorithms and techniques tested in numerous of aggregated data from real vineyards with different levels of weed development. Finally, the developed algorithm tested by implementing it on a UGV platform with promising results.

description: We consider disordered many-body systems with periodic time-dependent Hamiltonians in one spatial dimension. By studying the properties of the Floquet eigenstates, we identify two distinct phases: (i) a many-body localized (MBL) phase, in which almost all eigenstates have area-law entanglement entropy, and the eigenstate thermalization hypothesis (ETH) is violated, and (ii) a delocalized phase, in which eigenstates have volume-law entanglement and obey the ETH. MBL phase exhibits logarithmic in time growth of entanglement entropy for initial product states, which distinguishes it from the delocalized phase. We propose an effective model of the MBL phase in terms of an extensive number of emergent local integrals of motion (LIOM), which naturally explains the spectral and dynamical properties of this phase. Numerical data, obtained by exact diagonalization and time-evolving block decimation methods, suggests a direct transition between the two phases. Our results show that many-body localization is not destroyed by sufficiently weak periodic driving.

Guide d’évaluation des impacts environnementaux pour les technologies hydroliennes en mer : GHYDRO
Guide to the environmental impact evaluation of tidal stream technologies at sea : GHYDRO
Creators: name: Marines, France Energies
Publisher: name: France Energies Marines
Year: 2013

description: The main objective of this guide is to promote the environmental integration of a new type of construction at sea, for which there is very little feedback about the potential ecological impacts.

Due to the lack of French feedback (some exists at the international level) and the continued lack of knowledge concerning the marine environments targeted by tidal stream turbine technologies, the structural context in which environmental monitoring of the tidal stream projects will be developed is still in draft form. In terms of the environmental knowledge (physical and biological), as well as the regulatory and technological aspects (machines, installation, maintenance...), the assessment of the environmental impacts of tidal stream projects is still in its infancy. This guide proposes recommendations and methods that allow, for the first time, these different aspects to be taken into account. It makes recommendations on the choice of location, the description of the initial state and the ecological monitoring of tidal stream projects. The methodological guide currently represents a summary of the recommendations concerning the diverse physical parameters and biological compartments of the ecosystems that are potentially affected. The guide in no way represents a regulatory document for impact studies of tidal stream projects.
description: L'objectif principal de ce guide est de favoriser l'insertion environnementale d'un nouveau type d'aménagement en mer pour lequel il n'existe que très peu de retours d'expérience sur les incidences écologiques potentielles.

Du fait du manque de retours d'expérience français (quelques-uns à l'international) et de la méconnaissance, encore à ce jour, des milieux marins ciblés par les technologies hydroliennes, le contexte structurel dans lequel seront développés les suivis environnementaux des projets hydroliens est encore à l'état d'ébauche. Aussi bien pour la connaissance du milieu (physique et biologique), que pour les aspects réglementaires et technologiques (machines, installation, maintenance…), l'évaluation des impacts environnementaux des projets hydroliens n'en est qu'à ses prémices. Le présent guide propose des recommandations et des méthodes permettant une première prise en compte de ces différents aspects. Il formule des recommandations sur le choix d'implantation, la description de l'état initial et le suivi écologique des projets hydroliens. Ce guide méthodologique constitue à ce jour une synthèse de recommandations se rapportant aux divers paramètres physiques et compartiments biologiques de l'écosystème potentiellement impactés. Ce guide ne constitue en aucun cas un document réglementaire sur les études d'impacts des projets hydroliens.

description: Quantum teleportation has become a fundamental building block of quantum technologies, playing a vital role in the development of quantum communication networks. Here, we present a bidirectional quantum teleportation (BQT) protocol that enables even and odd coherent states to be transmitted and reconstructed over arbitrary distances in two directions. To this end, we employ the multipartite Glauber coherent state, comprising the Greenberger-Horne-Zeilinger, ground and Werner states, as a quantum resource linking distant partners Alice and Bob. The pairwise entanglement existing in symmetric and antisymmetric multipartite coherent states is explored, and by controlling the overlap and number of probes constructing various types of quantum channels, the teleportation efficiency of teleported states in both directions may be maximized. Besides, Alice's and Bob's trigger phases are estimated to explore their roles in our protocol using two kinds of quantum statistical speed referred to as quantum Fisher information (QFI) and Hilbert-Schmidt speed (HSS). Specifically, we show that the lower bound of the statistical estimation error, quantified by QFI and HSS, corresponds to the highest fidelity from Alice to Bob and conversely from Bob to Alice, and that the choice of the pre-shared quantum channel has a critical role in achieving high BQT efficiency. Finally, we show how to implement the suggested scheme on current experimental tools, where Alice can transfer her even coherent state to Bob, and at the same time, Bob can transfer his odd coherent state to Alice.
