description: We have used the Sydney University Stellar Interferometer (SUSI) to measure the angular diameter of beta Hydri. This star is a nearby G2 subgiant whose mean density was recently measured with high precision using asteroseismology. We determine the radius and effective temperature of the star to be 1.814+/-0.017 R_sun (0.9%) and 5872+/-44 K (0.7%) respectively. By combining this value with the mean density, as estimated from asteroseismology, we make a direct estimate of the stellar mass. We find a value of 1.07+/-0.03 M_sun (2.8%), which agrees with published estimates based on fitting in the H-R diagram, but has much higher precision. These results place valuable constraints on theoretical models of beta Hyi and its oscillation frequencies.

description: Simple mathematical models have been unable to predict the conditions leading to instabilities in a tuneable ring laser. Here, we propose a nonlinear iterative map model for tuneable ring lasers. Solving a reduced nonlinear Schrödinger equation for each component in the laser cavity, we obtain an algebraic map for each component. Iterating through the maps gives the total effect of one round trip. By neglecting the nonlinearity, we find a linearly chirped Gaussian to be the analytic fixed point solution, which we analyze asymptotically. We then numerically solve the full nonlinear model, allowing us to probe the underlying interplay of dispersion, modulation, and nonlinearity as the pulse evolves over hundreds of round trips of the cavity. In the nonlinear case, we find the chirp saturates, and the Fourier transform of the pulse becomes more rectangular in shape. Finally, for a nominal plane in the parameter space, we uncover a rich, sharp boundary separating the stable region and the unstable region where modulation instability degrades the pulse into an unsustainable state.

description: We reveal a novel regime of photon-pair generation driven by the interplay of multiple bound states in the continuum resonances in nonlinear metasurfaces. This non-degenerate photon-pair generation is derived from the hyperbolic topology of the transverse phase-matching and can enable orders-of-magnitude enhancement of the photon rate and spectral brightness, as compared to the degenerate regime. We show that the entanglement of the photon-pairs can be tuned by varying the pump polarization, which can underpin future advances and applications of ultra-compact quantum light sources.

Calogero-Sutherland model

description: We study the trigonometric quantum spin-Calogero-Sutherland model, and the Haldane-Shastry spin chain as a special case, using a Bethe-ansatz analysis. We harness the model's Yangian symmetry to import the standard tools of integrability for Heisenberg spin chains into the world of integrable long-range models with spins. From the transfer matrix with a diagonal twist we construct Heisenberg-style symmetries (Bethe algebra) that refine the usual hierarchy of commuting Hamiltonians (quantum determinant) of the spin-Calogero-Sutherland model. We compute the first few of these new conserved charges explicitly, and diagonalise them by Bethe ansatz inside each irreducible Yangian representation. This yields a new eigenbasis for the spin-Calogero-Sutherland model that generalises the Yangian Gelfand-Tsetlin basis of Takemura and Uglov. The Bethe-ansatz analysis involves non-generic values of the inhomogeneities. Our review of the inhomogeneous Heisenberg XXX chain, with special attention to how the Bethe ansatz works in the presence of fusion, may be of independent interest.
Identical response of insulators to irradiations by swift heavy ions: application to experiments on Gd2Ti2O7

Year: 2021

description: Track radii Re induced by swift heavy ions are studied. The experimental track data are analyzed in Gd2Ti2O7 pyrochlore in the range Se=6-54 keV/nm (Se - electronic stopping power) including irradiations by low and high velocity ions. The Analytical Thermal Spike Model (ATSM) is applied whose main features are reviewed. The track data of Gd2Ti2O7 exhibit scaling features which mean simple quantitative relationships with track sizes of other insulators controlled only by a single materials parameter (MP), the melting temperature Tm. The Re2-Se track evolution curve is described in the whole range of Se without the application of any individual fitting parameter and MPs apart Tm; the threshold for track formation Set=6.1/14.4 keV/nm for E<2 MeV/nucleon and E>8 MeV/nucleon, respectively. The unique role of Tm is a highly important limitation for the mechanism of track formation. The practical consequences of the results are discussed with respect of the estimation of irradiation parameters

Motivation and emotion dysregulation associated with pathological exercise among individuals with eating disorder psychopathology
Creators: name: Coniglio, Kathryn Ann
Publisher: name: No Publisher Supplied
Year: 2019

description: Pathological exercise, or exercise that is pursued in a rigid, compulsive, or extreme fashion, is omnipresent in eating disorder psychopathology. Despite this, minimal guidance exists in current treatment manuals for shaping pathological exercise behavior, which has led clinicians to prescribe total abstinence until treatment concludes. The purpose of this study was to better characterize pathological exercise using two relevant descriptive constructs – emotion regulation and motivation – to increase the specificity with which both pathological and healthy exercise is described, to ultimately inform treatment interventions. The present study aimed to identify types of motivation associated with exercise in a sample of college women (n=200) and a sample of adult women in the community with eating disorder psychopathology (n=211).  Latent profile analysis was used to characterize homogenous groups of individuals based on exercise motivation. These profiles were then compared on levels of eating and general psychopathology and emotion regulation difficulties. Three profiles emerged describing a sedentary, athlete, and eating disordered group in the first sample, and five profiles describing a sedentary, athlete, AN-like, weight loss, and healthy group were identified in the second sample. In both samples, the athlete group exhibited intrinsic motivation for exercise and scored significantly lower than the other groups on levels of general psychopathology, while the eating disordered groups displayed identified and extrinsic motivation for exercise and scored significantly higher than the other groups on body dissatisfaction and cognitive restraint. Findings indicate that motivation style may be a salient factor in defining pathological exercise and may also therefore be a clinically useful treatment target. Future studies should investigate the dynamic nature of motivation longitudinal throughout the course of illness.
Rational agency

Publisher: name: University of British Columbia
Year: 2010

description: It is claimed that action discourse provides us with a criterion of adequacy for a theory of action; that with action discourse we have a family of concepts which a theory of action must accommodate. After an exegesis of Davidson's essay "Agency", it is argued that his semantics of action is incompatible with our concepts of motivation and responsibility for action and of attributions of action and agency, and must, therefore, be rejected. A theory of rational agency is presented within which are to be found accounts of intention, coming to intend, intentional action, and an alternative semantics of action which connects the action essentially to agency. The theory of rational agency is then used to illuminate the concepts of trying, compulsion, autonomy and involuntariness, mistake, accident, and the so-called active-passive distinction.
Experiences of People with Intellectual Disabilities and Caregivers in Kenya: An Inclusive Research Study
Creators: name: Wanjagua, Rachael Wachera
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Voices of people with disabilities in Kenya have yet to influence disability services and the issues affecting their lives. This is in part due to the dominance of disability discourses from Global North contexts from which international policies on disability such as the United Nations Convention on the Rights of People with Disabilities borrow their guiding frameworks. People with intellectual disabilities face a much greater problem as they do not enjoy human and disability rights in much the same way their disabled and non-disabled counterparts. It is therefore critical to create knowledge about intellectual disabilities that is informed by perspectives from embodied experiences and reimagine discourses on intellectual disabilities.
The aim of this dissertation was to determine support needs and services of people with intellectual disabilities and caregivers in Laikipia County in Kenya. This was done through exploring their lived experiences, determining the barriers and facilitators to receiving services, resources and supports, and determining the factors that influenced availability or lack of services. The research was inclusive and participatory and used ethnographic qualitative methods of inquiry using interviews and focus group discussions with 10 people with intellectual disabilities and 10 caregivers. Additionally, two people with intellectual disabilities received research and ethics training and participated in data collection and dissemination as Research Assistants.
The key themes found were: representation, meaningful life, increased access to services, increased organizing and advocacy efforts, stigma, discrimination, colonization and exploitation. Future research needs to attend to cultural adaption of co-researcher training, empowerment of people with intellectual disabilities in all research processes, working with support personnel who have the interest to empower researchers with intellectual disabilities, and a more intentional focus on decolonization, cultural and systems-levels barriers facing people with intellectual disabilities and their caregivers as well as their full participation in research.

description: Using resonant interaction of three Rydberg atoms with a single-mode microwave cavity, we consider a realization of three-qubit Grover search algorithm in the presence of weak cavity decay, based on a previous idea for three-qubit quantum gate [Phys. Rev. A 73, 064304 (2006)]. We simulate the searching process under the influence of the cavity decay and show that our scheme could be achieved efficiently to find the marked state with high fidelity. The required operations are very close to the reach with current cavity QED techniques.

description: Societal biases resonate in the retrieved contents of information retrieval (IR) systems, resulting in reinforcing existing stereotypes. Approaching this issue requires established measures of fairness in respect to the representation of various social groups in retrieval results, as well as methods to mitigate such biases, particularly in the light of the advances in deep ranking models. In this work, we first provide a novel framework to measure the fairness in the retrieved text contents of ranking models. Introducing a ranker-agnostic measurement, the framework also enables the disentanglement of the effect on fairness of collection from that of rankers. To mitigate these biases, we propose AdvBert, a ranking model achieved by adapting adversarial bias mitigation for IR, which jointly learns to predict relevance and remove protected attributes. We conduct experiments on two passage retrieval collections (MSMARCO Passage Re-ranking and TREC Deep Learning 2019 Passage Re-ranking), which we extend by fairness annotations of a selected subset of queries regarding gender attributes. Our results on the MSMARCO benchmark show that, (1) all ranking models are less fair in comparison with ranker-agnostic baselines, and (2) the fairness of Bert rankers significantly improves when using the proposed AdvBert models. Lastly, we investigate the trade-off between fairness and utility, showing that we can maintain the significant improvements in fairness without any significant loss in utility.

Interface dynamics of microscopic cavities in water

description: An analytical description of the interface motion of a collapsing nanometer-sized spherical cavity in water is presented by a modification of the Rayleigh-Plesset equation in conjunction with explicit solvent molecular dynamics simulations. Quantitative agreement is found between the two approaches for the time-dependent cavity radius $R(t)$ at different solvent conditions while in the continuum picture the solvent viscosity has to be corrected for curvature effects. The typical magnitude of the interface or collapse velocity is found to be given by the ratio of surface tension and fluid viscosity, $v\simeqγ/η$, while the curvature correction accelerates collapse dynamics on length scales below the equilibrium crossover scales ($\sim$1nm). The study offers a starting point for an efficient implicit modeling of water dynamics in aqueous nanoassembly and protein systems in nonequilibrium.

Impact of Rumination on Cognitive Reappraisal Neural Activity in Social Anxiety and Major Depression
Creators: name: Davey, Delaney
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Major depressive disorder (MDD) and social anxiety disorder (SAD) are highly prevalent internalizing disorders characterized by poor emotion regulation. Both disorders are associated with high use of maladaptive emotion regulation approaches (e.g., rumination) and low use of adaptive regulation approaches (e.g., reappraisal). Emerging research indicates that rumination may interfere with cognitive reappraisal; yet, the impact of rumination on brain response during reappraisal is under-researched. We hypothesized that individuals with MDD or SAD would exhibit elevated levels of rumination and report less reappraisal than a healthy control (HC) group and predicted that these two emotion regulation strategies would be negatively correlated in the diagnostic groups. Additionally, we expected that self-reported rumination would correspond with activity in prefrontal cognitive control regions implicated in reappraisal. To test hypotheses, self-reported rumination and reappraisal from diagnostic groups [MDD (n = 60), SAD (n = 50), HC (n = 38)] were submitted to analyses of variance (ANOVAs). Partial correlations were conducted within the clinical groups controlling for symptom severity to evaluate the relationships between these two types of emotion regulation strategies. During fMRI, participants completed a validated emotion regulation task which involved reappraising (i.e., decreasing negative affect) as compared to viewing aversive images. Regression analysis was used to investigate whether self-reported rumination modulated activity in brain regions implicated in cognitive reappraisal during reappraisal. ANOVA results showed MDD and SAD groups exhibited elevated levels of rumination relative to the HC group, whereas reappraisal was lower among the clinical groups compared to the HC group. MDD and SAD groups reported similar levels of rumination and reappraisal. Partial correlations did not reveal an association between self-reported rumination and reappraisal. Thus, hypotheses were partially supported. Finally, fMRI analysis showed self-reported rumination modulated dorsolateral prefrontal cortex activity during reappraisal among the clinical groups (MDD, SAD), such that higher levels of rumination were associated with less dorsolateral prefrontal cortex activation. In line with our hypotheses, neuroimaging results suggest that rumination, a maladaptive cognitive strategy, may interfere with more adaptive forms of emotion regulation. Findings have the potential to increase our understanding of emotion regulation in MDD and SAD and inform interventions.

description: We review recent progress in applying the AdS/CFT correspondence to finite-temperature field theory. In particular, we show how the hydrodynamic behavior of field theory is reflected in the low-momentum limit of correlation functions computed through a real-time AdS/CFT prescription, which we formulate. We also show how the hydrodynamic modes in field theory correspond to the low-lying quasinormal modes of the AdS black p-brane metric. We provide a proof of the universality of the viscosity/entropy ratio within a class of theories with gravity duals and formulate a viscosity bound conjecture. Possible implications for real systems are mentioned.

description: Dans le golfe de Gascogne, sur le rebord du plateau aquitain à des profondeurs d’eau comprises entre 140 m et 220 m, des bulles de méthane s’échappent du fond de le mer. Le ROV Victor, robot câblé télé-opéré depuis le navire Pourquoi pas ? a pu photographier au cours de la campagne GAZCOGNE2 en 2013 ces sites d’émissions dits de fluides froids (dénommés « cold seeps » en anglais). Ces sites sont de véritables oasis de vie avec une activité microbienne intense. Les sédiments apparaissent ici et là noirs (car réduits) et recouverts partiellement de tapis microbiens (filaments blancs). Le paysage sous-marin du rebord du plateau aquitain correspond à des structures carbonatées authigènes dérivées du méthane ; ces carbonates ont en effet pu précipiter grâce à la circulation de méthane en subsurface. La faune benthique est relativement abondante et variée, profitant de ce substrat dur, qu’offrent les carbonates, pour s’y abriter ou s’y fixer. De nombreux organismes suspensivores (e. g. éponges et huîtres Gryphaeidae) ont pu être observés pendant ces plongées, ainsi qu’une forte densité de poissons (chinchards et sangliers). Différents outils de mesures et prélèvements ont été déployés par le ROV Victor dont le Pegaz, un préleveur conique de gaz sous pression.

description: I investigate superconducting states in a quasi-2D Holstein model using the dynamical cluster approximation (DCA). The effects of spatial fluctuations (non-local corrections) are examined and approximations neglecting and incorporating lowest-order vertex corrections are computed. The approximation is expected to be valid for electron-phonon couplings of less than the bandwidth. The phase diagram and superconducting order parameter are calculated. Effects which can only be attributed to theories beyond Migdal--Eliashberg theory are present. In particular, the order parameter shows momentum dependence on the Fermi-surface with a modulated form and s-wave order is suppressed at half-filling. The results are discussed in relation to Hohenberg's theorem and the BCS approximation.

description: Relativistic simulations in 3+1 dimensions typically monitor the Hamiltonian and momentum constraints during evolution, with significant violations of these constraints indicating the presence of instabilities. In this paper we rewrite the momentum constraints as first-order evolution equations, and show that the popular BSSN formulation of the Einstein equations explicitly uses the momentum constraints as evolution equations. We conjecture that this feature is a key reason for the relative success of the BSSN formulation in numerical relativity.

description: We analyze the properties of the quasiparticle excitations of metallic antiferromagnetic states in a strongly correlated electron system. The study is based on dynamical mean field theory (DMFT) for the infinite dimensional Hubbard model with antiferromagnetic symmetry breaking. Self-consistent solutions of the DMFT equations are calculated using the numerical renormalization group (NRG). The low energy behavior in these results is then analyzed in terms of renormalized quasiparticles. The parameters for these quasiparticles are calculated directly from the NRG derived self-energy, and also from the low energy fixed point of the effective impurity. They are found to be in good agreement. We show that the main low energy features of the $\bf k$-resolved spectral density can be understood in terms of the quasiparticle picture. We also find that Luttinger's theorem is satisfied for the total electron number in the doped antiferromagnetic state.

description: We present results from a suite of binary merging cluster simulations. The hydrodynamical cluster simulations are performed employing a smoothed particle hydrodynamics (SPH) formulation in which gradient errors are strongly reduced by means of an integral approach. We consider adiabatic as well as radiative simulations, in which we include gas cooling, star formation and energy feedback from supernovae. We explore the effects of merging on the thermodynamic structure of the intracluster gas of the final merger remnant. In particular, we study how core entropy is generated during the merging and the stability properties of the initial cool-core profile against disruption. To this end, we consider a range of initial mass ratio and impact parameters. Final entropy profiles of our adiabatic merging simulations are in good accord with previous findings (ZuHone 2011), with cool-cores being disrupted for all of the initial merging setups. For equal-mass off-axis mergers, we find that a significant contribution to the final primary core entropy is due to hydrodynamic instabilities generated by rotational motions, which are induced by tidal torques during the first pericenter passage. In radiative simulations, cool-cores are more resilient against heating processes; nonetheless, they are able to maintain their integrity only in the case of off-axis mergers with very unequal masses. We suggest that these results are robust against changes in the gas physical modeling, in particular to the inclusion of AGN thermal feedback. Our findings support the view that the observed core cluster morphology emerges naturally in a merging cluster context, and conclude that the merging angular momentum is a key parameter in shaping the thermodynamical properties of the final merger remnant.

description: The standard argument for the Lorentz invariance of the thermodynamic entropy in equilibrium is based on the assumption that it is possible to perform an adiabatic transformation whose only outcome is to accelerate a macroscopic body, keeping its rest mass unchanged. The validity of this assumption constitutes the very foundation of relativistic thermodynamics and needs to be tested in greater detail. We show that, indeed, such a transformation is always possible, at least in principle. The only two assumptions invoked in the proof are that there is at least one inertial reference frame in which the second law of thermodynamics is valid and that the microscopic theory describing the internal dynamics of the body is a field theory, with Lorentz invariant Lagrangian density. The proof makes no reference to the connection between entropy and probabilities and is valid both within classical and quantum physics. To avoid any risk of circular reasoning, we do not postulate that the laws of thermodynamics are the same in every reference frame, but we obtain this fact as a direct consequence of the Lorentz invariance of the entropy.

We find that for magnetic (Fe, Co and Ni) and non-magnetic (Si and Ge) solids, the exact-exchange current-spin-density functional approach does not significantly improve the accuracy of the corresponding spin-density functional results.

Listening to our data users: A qualitative study to better know their perception of our data and metadata
Creators: name: Gallis, Quentin
Publisher: name: Zenodo

description: In the open science “era”, data centers are on the frontline of data sharing. Sharing data collected by itself and by and others, the French Center for Socio-Political Data (CDSP) faces multiple problematics concerning the usability of its services, especially those related to the FAIR principles. The CDSP has been using DDI to document its data since its creation in 2006. If the standard provides a rich documentation, up to the level of the variable, what are the other elements to be taken into consideration for a “good” data user experience? Does DDI answer to all of the four letters of FAIR? In order to get a better grasp of the secondary data users' point of view, we have undertaken a qualitative study: we conducted semi-directive interviews with people having downloading data at least once in the last year from the CDSP. This study has taught us that the documentation of data and metadata is perceived as a great strength of our data, permitting optimal reuse. However, if this fact is encouraging in regard to the academic world's efforts to open science, a practical limit emerges. This showed us that even if standards are a huge step to data dissemination, we still have efforts to do to make our data more accessible. This paper will present the outcomes of our survey, as well as our next steps to make our DDI metadata and our data more findable and discoverable.

description: We introduce a spin-orbit assisted electron-phonon (e-ph) coupling mechanism for carriers in semiconductor quantum wells and predict qualitatively the form and shape of anticrossings between the cyclotron resonance (CR) and optical (LO and TO) phonons. Since this e-ph interaction involves the electron spin it makes the predicted TO-CR anticrossing dependent on the filling factor and therefore on the polarization of the 2D electron gas in the quantum well.

description: We present the results of photometric and spectroscopic monitoring campaigns of the changing look AGN NGC 3516 carried out in 2018 to 2020 covering the wavelength range from the X-ray to the optical. The facilities included the telescopes of the CMO SAI MSU, the 2.3-m WIRO telescope, and the XRT and UVOT of Swift. We found that NGC 3516 brightened to a high state and could be classified as Sy1.5 during the late spring of 2020. We have measured time delays in the responses of the Balmer and He II 4686 lines to continuum variations. In the case of the best-characterized broad H-beta line, the delay to continuum variability is about 17 days in the blue wing and is clearly shorter, 9 days, in the red, which is suggestive of inflow. As the broad lines strengthened, the blue side came to dominate the Balmer lines, resulting in very asymmetric profiles with blueshifted peaks during this high state. During the outburst the X-ray flux reached its maximum on 1 April 2020 and it was the highest value ever observed for NGC 3516 by the Swift observatory. The X-ray hard photon index became softer, about 1.8 in the maximum on 21 Apr 2020 compared to the mean about 0.7 during earlier epochs before 2020. We have found that the UV and optical variations correlated well (with a small time delay of 1-2 days) with the X-ray until the beginning of April 2020, but later, until the end of Jun. 2020, these variations were not correlated. We suggest that this fact may be a consequence of partial obscuration by Compton-thick clouds crossing the line of sight.

One-loop MHV Rules and Pure Yang-Mills

description: It has been known for some time that the standard MHV diagram formulation of perturbative Yang-Mills theory is incomplete, as it misses rational terms in one-loop scattering amplitudes of pure Yang-Mills. We propose that certain Lorentz violating counterterms, when expressed in the field variables which give rise to standard MHV vertices, produce precisely these missing terms. These counterterms appear when Yang-Mills is treated with a regulator, introduced by Thorn and collaborators, which arises in worldsheet formulations of Yang-Mills theory in the lightcone gauge. As an illustration of our proposal, we show that a simple one-loop, two-point counterterm is the generating function for the infinite sequence of one-loop, all-plus helicity amplitudes in pure Yang-Mills, in complete agreement with known expressions.

Particle interference as a test of Lorentz-violating electrodynamics

description: In Lorentz-violating electrodynamics a steady current (and similarly a static charge) generates both static magnetic and electric fields. These induced fields, acting on interfering particles, change the interference pattern. We find that particle interference experiments are sensitive to small Lorentz violating effects, and thus they can be used to improve current bounds on some Lorentz-violating parameters.

description: Le littoral Nord - Pas-de-Calais / Picardie montre de nombreux signes de dysfonctionnements induits principalement par l’activité anthropique. Ces signes se manifestent presque toujours par un déséquilibre des populations, qu’elles soient animales ou végétales. En effet, certaines espèces dominent. C’est le cas de la Prymnesiophycée Phaeocystis sp., une algue phytoplanctonique naturelle qui prolifère tous les ans au printemps. Le cycle de développement de l’espèce évolue depuis quelques années (modification de l’amplitude, de la durée et de l’extension graphique du bloom) et est fortement lié à la dynamique des sels nutritifs comme les nitrates et les phosphates par exemple. Dans le cadre de l’évaluation de l’influence des apports continentaux en éléments nutritifs sur d’éventuels processus d’eutrophisation du milieu marin, de l’estimation de l’efficacité des stations d’épuration à éliminer de telles substances et afin d’établir un suivi à long terme permettant de suivre l’évolution de la qualité des eaux littorales, le réseau de Suivi Régional des Nutriments (SRN) a été mis en place par l’Ifremer en collaboration avec l’Agence de l’Eau Artois- Picardie en 1992 afin de compléter le réseau REPHY (Réseau Phytoplancton et Phycotoxines). Ce rapport présente les principaux résultats de l’année 2024 en termes d’évolution temporelle des paramètres physico-chimiques et biologiques caractéristiques des masses d’eaux échantillonnées au niveau des points de surveillance de trois radiales situées à Dunkerque, à Boulogne-sur-Mer et en Baie de Somme.

description: De nombreuses personnes subissent des brûlures chaque année en Suisse et sont suivies en ergothérapie. Cette brûlure, bien que différente à chaque fois, peut avoir des conséquences psychologiques, physiques, et sociales pour l'enfant. Celui-ci doit développer des stratégies d'adaptation afin de passer à travers cette période douloureuse. Cette recherche vise à décrire la résilience telle que vécue par des personnes ayant subi une brûlure grave dans l'enfance et à explorer l'expérience des ergothérapeutes travaillant avec cette population. De plus, elle vise à identifier les difficultés et les facilitateurs des personnes ayant subi une brûlure. Elle ressort les stratégies utilisées par celles-ci pour s'adapter à leur nouvelle situation ainsi que l'apport des ergothérapeutes pour les y aider. Finalement, elle cherche à mettre en avant les mécanismes d'adaptation qui ont aidé cette population à développer une capacité de résilience ainsi que des recommandations pour la faciliter.

description: Installée dans la rade de Boulogne-sur-Mer et inaugurée le 25 novembre 2004, la station MAREL Carnot mesurait initialement, toutes les 20 minutes, la salinité, la température de l’eau et de l’air, la fluorescence, la turbidité, la concentration en oxygène dissous, le pourcentage de saturation en oxygène, le P.A.R., l’humidité relative, la direction et la vitesse du vent, la hauteur d’eau et toutes les 12 heures, la concentration en nitrate, en phosphate et en silicium. Depuis 2014 (2010 pour les nutriments) et jusqu’en 2024, les paramètres météo ainsi que le P.A.R. et les nutriments ne sont plus mesurés. Ce rapport vise à présenter les principaux éléments utiles à l’utilisateur des données afin de pouvoir adapter son étude en fonction de la disponibilité des données, de leur qualité et, bien entendu, de son objectif. Les résultats des paramètres température, salinité, turbidité, concentration et saturation en oxygène, fluorescence sont présentés de manière plus détaillée afin de mettre en évidence les cycles saisonniers caractéristiques de cet écosystème.

description: Here, we present theoretical studies of the temperature and magnetic field dependences of the Coulomb drag transresistivity between two parallel layers of two dimensional electron gases in quantum Hall regime near half filling of the lowest Landau level. It is shown that Fermi-liquid interactions between the relevant quasiparticles could give a significant effect on the transresistivity, providing its independence of the interlayer spacing for spacings taking on values reported in the experiments. Obtained results agree with the experimental evidence.
