description: A quantum theory of gravity implies a fine-grained structure of spacetime, which can be conveniently modeled as some form of pixelation at the Planck scale, with potentially observable consequences. In this work, we build upon previous results to investigate the effect of pixelation on the quantum vacuum, making use of the framework of Doubly Special Relativity (DSR). At the center of the DSR approach is an observer dependent length scale, defining the pixelation of spacetime. A key feature of quantum field theory in DSR is the dispersive nature of the vacuum state and the associated appearance of curvature in momentum space. As a result, the standard treatment of the renormalized stress-energy-momentum tensor acquires correction terms. As an illustration, we present here a calculation of the thermal vacuum and modified Casimir effect, using both modified propagators and momentum measures. We choose a consistent choice of momentum space metric that both generates the modified dispersion relations we use and preserves the Lorentz invariant character of the results obtained. Put together this constitutes a consistent calculation framework we can apply to other more complex scenarios.

description: In this paper, we prove the following result. Let $α$ be any real number between $0$ and $2$. Assume that $u$ is a solution of $$ \left\{\begin{array}{ll} (-Δ)^{α/2} u(x) = 0 , \;\; x \in \mathbb{R}^n ,\\ \displaystyle\underset{|x| \to \infty}{\underline{\lim}} \frac{u(x)}{|x|^γ} \geq 0 , \end{array} \right. $$ for some $0 \leq γ\leq 1$ and $γ< α$. Then $u$ must be constant throughout $\mathbb{R}^n$. This is a Liouville Theorem for $α$-harmonic functions under a much weaker condition. For this theorem we have two different proofs by using two different methods: One is a direct approach using potential theory. The other is by Fourier analysis as a corollary of the fact that the only $α$-harmonic functions are affine.

description: It is well accepted that adoption of innovations are described by S-curves (slow start, accelerating period, and slow end). In this paper, we analyze how much information on the dynamics of innovation spreading can be obtained from a quantitative description of S-curves. We focus on the adoption of linguistic innovations for which detailed databases of written texts from the last 200 years allow for an unprecedented statistical precision. Combining data analysis with simulations of simple models (e.g., the Bass dynamics on complex networks) we identify signatures of endogenous and exogenous factors in the S-curves of adoption. We propose a measure to quantify the strength of these factors and three different methods to estimate it from S-curves. We obtain cases in which the exogenous factors are dominant (in the adoption of German orthographic reforms and of one irregular verb) and cases in which endogenous factors are dominant (in the adoption of conventions for romanization of Russian names and in the regularization of most studied verbs). These results show that the shape of S-curve is not universal and contains information on the adoption mechanism. (published at "J. R. Soc.

QCD $θ$-vacua from the chiral limit to the quenched limit

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We investigate the dependence of the QCD vacuum structure on the $θ$-angle and quark mass, using the Di-Vecchia--Veneziano model. Although the Di-Vecchia--Veneziano model is a chiral effective model, it contains the topological properties of the pure Yang--Mills theory. It is shown that within this model, the ground state energies for all $θ$ are continuous functions of quark mass from the chiral limit to the quenched limit, even including the first order phase transition at $θ= π$. Based on this effective model, we discuss (i) how the ground state depends on quark mass, and (ii) why the phase transition at $θ= π$ is present both in the chiral and quenched limit. In order to analyze the relation between quark mass and the $θ$-vacua, we calculate the chiral condensate as a function of quark mass. Also, considering the presence of the innate metastable states included in the QCD $θ$-vacuum, we also give a unified understanding of the phase transitions at $θ= π$ in the chiral and quenched limit.

description: Stochastic optimization is a vital field in the realm of mathematical optimization, finding applications in diverse areas ranging from operations research to machine learning. In this paper, we introduce a novel first-order optimization algorithm designed for scenarios where Markovian noise is present, incorporating Nesterov acceleration for enhanced efficiency. The convergence analysis is performed using an assumption on noise depending on the distance to the solution. We also delve into the consensus problem over Markov-varying networks, exploring how this algorithm can be applied to achieve agreement among multiple agents with differing objectives during changes in the communication system. To show the performance of our method on the problem above, we conduct experiments to demonstrate the superiority over the classic approach.

description: Dans le cadre de l’action Amélioration des connaissances scientifiques - Volet Identification de Stocks du projet IPERDMX, une étude pour déterminer si La Réunion montre une population ou plusieurs groupes séparés, a été réalisée chez 13 espèces de poissons (Aphareus rutilans, Aprion virescens, Cephalopholis aurantia, Epinephelus fasciatus, Etelis carbunculus, Lethrinus rubrioperculatus, Lutjanus kasmira, Lutjanus notatus, Mulloidichthys pfluegeri, Pristipomoides argyrogrammicus, Pristipomoides filamentosus, Variola albimarginata, Variola louti). L’outil pour déterminer s’il existe une ou plusieurs populations est l’otolithe, pièce calcifiée de l’oreille interne des poissons. Sa forme est le résultat des effets de la génétique de l’individu et de l’environnement qu’il a rencontré au cours de sa vie. Pour cette étude, 2392 otolithes ont été prélevés et analysés. Parmi les espèces, 544 otolithes ont été analysés pour Lutjanus kasmira et à l’inverse, seuls 31 otolithes ont été échantillonnés et traités pour Aprion virescens. Pour chaque espèce, l’analyse a été réalisée en 2 étapes en regardant premièrement les effets confondants potentiels sur la forme des otolithes que sont la taille du poisson, la symétrie des otolithes droit et gauche, le dimorphisme sexuel et l’effet géographique. Cette première étape permet de comprendre l’importance des différents effets qui influencent la forme de l’otolithe pour les intégrer dans la deuxième étape de façon à ne tester que l’effet géographique sur la forme des otolithes. Lorsque cet effet géographique est significatif lors de la première étape, la deuxième étape consiste à quantifier et comprendre cet effet avec 2 approches utilisées en parallèle que sont la Classification Ascendante Hiérarchique (CAH, n’utilisant pas d’informations préalables de classification) et l’Analyse Discriminante Linéaire (LDA, utilisant les positions géographiques pour définir les groupes à tester). Parmi les 13 espèces testées, seuls les résultats chez 2 espèces (Etelis carbunculus et Pristipomoides filamentosus) montrent 2 sous-ensembles géographiques pouvant laisser à penser à 2 unités de gestion/stocks présentes autour de l’île de La Réunion. Pour les 11 autres espèces, l’ile de La Réunion semble former une seule unité de gestion par espèce. Cependant, tous ces résultats mériteront d’être complétés dans le futur via un échantillonnage spatial plus important.

title: Reciprocal Preferences in Matching Markets

Publisher: name: Universitätsbibliothek der Ludwig-Maximilians-Universität München
Year: 2023

description: Agents with reciprocal preferences prefer to be matched to a partner who also likes to collaborate with them. In this paper, we introduce and formalize reciprocal preferences, apply them to matching markets, and analyze the implications for mechanism design. Formally, the preferences of an agent can depend on the preferences of potential partners and there is incomplete information about the partners’ preferences. We find that there is no stable mechanism in standard two-sided markets. Observing the final allocation of the mechanism enables agents to learn about each other's preferences, leading to instability. However, in a school choice setting with one side of the market being non-strategic, modified versions of the deferred acceptance mechanism can achieve stability. These results provide insights into non-standard preferences in matching markets, and their implications for efficient information and mechanism design.
Cooperative decay of an ensemble of atoms in a one-dimensional chain with a single excitation
Creators: name: Piovella, Nicola
Publisher: name: arXiv
Year: 2024
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We propose a new expression of the cooperative decay rate of a one-dimensional chain of N two-level atoms in the single-excitation configuration. From it, the interference nature of superradiance and subradiance arises naturally, without the need of solving the eigenvalue problem of the atom-atom interaction Green function. The cooperative decay rate can be interpreted as the imaginary part of the expectation value of the effective non-Hermitian Hamiltonian of the system, evaluated over a generalized Dicke state of N atoms in the single-excitation manifold. Whereas the subradiant decay rate is zero for an infinite chain, it decreases as 1/N for a finite chain. A simple approximated expression for the cooperative decay rate is obtained as a function of the lattice constant d and the atomic number N. The results are obtained first for the scalar model and then extended to the vectorial light model, assuming all the dipoles aligned.

description: Diese Masterarbeit beschäftigt sich mit Selektionsprozessen der Deutschförderklassen und richtet ihren Fokus auf den Diskurs rund um die Deutschförderklassen sowie die Einstellungen und Erfahrungen von Eltern dazu. Im Mittelpunkt stehen die Diskurspositionen des politischen, wissenschaftlichen und fachöffentlichen Diskurses und die Positionierungen der Eltern zum Diskursspektrum. Die Elternstimmen zeigen wichtige Perspektiven auf, um die Komplexität der Selektionsprozesse in ihrer Gesamtheit verstehen zu können. Um die Forschungsfrage(n) dieser Arbeit zu beantworten, wurden in einem ersten Schritt die Diskurspositionen aus der Politik erhoben, um argumentativ die Vagheit politischer Positionen durch Wissenschaft und Fachöffentlichkeit aufzudecken und ihre diskriminierenden Folgen darzustellen. Die Schule als Exekutive des Staates vertritt dessen Interessen, indem sie selektiert, segregiert und Schüler*innen zurückstellt, gleichwohl dies für die Bildungs- und Berufslaufbahnen der Schüler*innen mit bedeutenden Benachteiligungen einhergeht. In einem zweiten Schritt wurden die Alltagserfahrungen und -interpretationen der Eltern zu den Positionen des Diskurses erhoben, was gleichzeitig neue Perspektiven auf das Thema und eine Erweiterung des Diskurses eröffnete. Die qualitative Studie zeigt, dass durch die gesetzliche Einführung der Deutschförderklassen eine gewollte Selektion angestoßen wird, deren negative Effekte in politischen Argumenten nicht offengelegt werden. Zudem wird der diskursive Ausschluss der Eltern deutlich, wenn die Diskriminierungsmechanismen, denen Eltern ausgesetzt sind, im Gespräch mit ihnen aufgedeckt werden.

description: Applying a macroscopic reduction procedure on the improved quantum molecular dynamics (ImQMD) model, the energy dependences of the nucleus-nucleus potential, the friction parameter, and the random force characterizing a one-dimensional Langevin-type description of the heavy-ion fusion process are investigated. Systematic calculations with the ImQMD model show that the fluctuation-dissipation relation found in the symmetric head-on fusion reactions at energies just above the Coulomb barrier fades out when the incident energy increases. It turns out that this dynamical change with increasing incident energy is caused by a specific behavior of the friction parameter which directly depends on the microscopic dynamical process, i.e., on how the collective energy of the relative motion is transferred into the intrinsic excitation energy. It is shown microscopically that the energy dissipation in the fusion process is governed by two mechanisms: One is caused by the nucleon exchanges between two fusing nuclei, and the other is due to a rearrangement of nucleons in the intrinsic system. The former mechanism monotonically increases the dissipative energy and shows a weak dependence on the incident energy, while the latter depends on both the relative distance between two fusing nuclei and the incident energy. It is shown that the latter mechanism is responsible for the energy dependence of the fusion potential and explains the fading out of the fluctuation-dissipation relation.

description: We study the damping of an oscillating scalar field in a Friedmann-Robertson-Walker spacetime by perturbative processes, taking into account the finite density effects that interactions with the plasma of decay products have on the damping rate. The scalar field may be identified with the inflaton, in which case this process leads to the reheating of the universe after inflation. It can also resemble a modulus that dominates the energy density of the universe at later times. We find that the finite density corrections to the damping rate can have a drastic effect on the thermal history and considerably increase both, the maximal temperature in the early universe and the reheating temperature at the onset of the radiation dominated era. As a result abundance of some Dark Matter candidates may be considerably larger than previously estimated. We give improved analytic estimates for the maximal and the reheating temperatures and confirm them numerically in a simple model.

description: Bei der weiblichen Genitalverstümmelung/-beschneidung (FGM/C) handelt es sich um eine tradierte, kulturelle, meist universelle Praxis, von der weltweit ungefähr 200 Millionen Mädchen und Frauen betroffen sind. Aufgrund steigender Migrationsbewegungen sind auch Länder wie Österreich mit diesem Thema konfrontiert. Diese Arbeit erfasst die Einstellungen afrikanischer Frauen, die aus einem praktizierenden Herkunftsland stammen und nach Wien migriert sind, gegenüber der weiblichen Genitalbeschneidung. Dabei sollen die Faktoren, die zu einer möglichen veränderten Einstellung führten, der Zusammenhang zwischen persönlicher Betroffenheit und der Einstellung, die Rolle von FGM/C in Wien, sowie die mögliche gegenseitige Beeinflussung zwischen den befragten Frauen und Personen im Herkunftsland untersucht werden.

Due to migration, countries like Austria are also confronted with this issue. This study explores the attitudes of African women who migrated from a practicing country to Vienna towards FGM/C. In this context, the factors that led to possible changes in attitudes, the relationship between personal experiences and the attitude, the role of FGM/C in Vienna and the influence of the diaspora on the perspectives of people in their country of origin and vice versa are examined.
title: Wie kann die Europäische Kommission Desinformationen in digitalen Öffentlichkeiten regulieren und gleichzeitig die demokratischen Freiheiten wahren?
Creators: name: Opitz, Steffen
Year: 2021

description: Desinformationen versuchen gezielt Einfluss auf die Konsensbildung einer Gesellschaft in digitalen Öffentlichkeiten zu nehmen. Sie sind kein digitales oder neuartiges Problem, sondern können in jeder Form von Öffentlichkeit auftreten, jedoch haben sie sich im Internet als besonders effektiv gezeigt. Folgende Forschungsfrage wurde aufgestellt: Wie kann die Europäische Kommission Desinformationen in digitalen Öffentlichkeiten regulieren und gleichzeitig die demokratischen Freiheiten wahren? Ziel dieser literaturbasierten Arbeit ist, verschiedene Forschungsansätze miteinander zu verknüpfen und in einer Sekundärforschung ein Lösungsansatz zu präsentieren, der die Forschungsfrage beantworten kann. Hierzu wurden die Chancen von digitalen Öffentlichkeiten nach dem Konzept von Hannah Arendt und die Gefahren von Desinformationen nach der Konzeption von Clair Wardle und Hossein Derakhshan präsentiert, um anhand dieser ein Spannungsverhältnis aufzuzeigen, welches in dieser Form nicht bestehen bleiben soll. Diese Arbeit sieht die Selbstregulierung der Digitalkonzerne kritisch und betrachtet die Regulierung der Europäischen Kommission als einen temporären Kompromiss zum Schutz von Öffentlichkeit. Diese Arbeit hat daher die Effektivität von Regularien erklären wollen und als Antwort auf die Forschungsfrage einen alternativen Lösungsansatz präsentieren. Die Forschungsfrage kann mit zwei Strängen beantwortet werden. Der erste Strang beschreibt die verantwortungsvolle Regulierung, unter Wahrung der europäischen Freiheitswerte, von Plattformen und Digitalkonzernen durch die Europäische Kommission. Diese besitzt gesellschaftliche und politische Legitimation, um einen weitreichenden Eingriff auf die Plattformen und den digitalen Öffentlichkeiten vorzunehmen. Der zweite Strang verfolgt eine souveräne und medienkompetente europäische Gesellschaft, die gegenüber Desinformationen weniger anfällig ist.

description: We introduce several homotopy equivalence relations for proper holomorphic mappings between balls. We provide examples showing that the degree of a rational proper mapping between balls (in positive codimension) is not a homotopy invariant. In domain dimension at least 2, we prove that the set of homotopy classes of rational proper mappings from a ball to a higher dimensional ball is finite. By contrast, when the target dimension is at least twice the domain dimension, it is well known that there are uncountably many spherical equivalence classes. We generalize this result by proving that an arbitrary homotopy of rational maps whose endpoints are spherically inequivalent must contain uncountably many spherically inequivalent maps. We introduce Whitney sequences, a precise analogue (in higher dimensions) of the notion of finite Blaschke product (in one dimension). We show that terms in a Whitney sequence are homotopic to monomial mappings, and we establish an additional result about the target dimensions of such homotopies.

description: We discover new Voronoi formulae for automorphic forms on GL($n$) for $n\geq 4$. There are $[n/2]$ different Voronoi formulae on GL($n$), which are Poisson summation formulae weighted by Fourier coefficients of the automorphic form with twists by some hyper-Kloosterman sums.

description: The surface tension of compliant materials such as gels provides resistance to deformation in addition to and sometimes surpassing that due to elasticity. This article studies how surface tension changes the contact mechanics of a small hard sphere indenting a soft elastic substrate. Previous studies have examined the special case where the external load is zero, so contact is driven by adhesion alone. Here, we tackle the much more complicated problem where, in addition to adhesion, deformation is driven by an indentation force. We present an exact solution based on small strain theory. The relation between indentation force (displacement) and contact radius is found to depend on a single dimensionless parameter: $ω=σ(μR)^{-2/3}(9πW_{\textrm{ad}}/4)^{-1/3}$, where $σ$ and $μ$ are the surface tension and shear modulus of the substrate, $R$ is the sphere radius, and $W_{\textrm{ad}}$ is the interfacial work of adhesion. Our theory reduces to the Johnson-Kendall-Roberts theory and Young-Dupré equation in the limits of small and large $ω$ respectively, and compares well with existing experimental data. Our results show that, although surface tension can significantly affect the indentation force, the magnitude of the pull-off load in the partial wetting liquid-like limit is reduced only by 1/3 compared with the JKR limit, and the pull-off behavior is completely determined by $ω$.

description: Within the European Data Collection Framework (DCF) regulation, member States are obliged to collect and provide socio-economic data on fisheries as a basis for advice on fisheries managements or for other uses. In mainland France, the data producer is the Service de la Statistique et de la Prospective (SSP) of the Ministry of Agriculture and Food. The SSP relies on its two partners for data collection: Ifremer, which carries out fieldworks surveys, and the Laboratoire d'Economie et de Management de Nantes-Atlantique (Lemna), which collects accounting data from management centers. This document presents the steps for the construction of the annual sampling plan that will be used for the collection of economic data. This is the first step in the construction of socio-economic indicators, prior to data collection and validation.

description: We investigate the CO excitation of normal star forming disk galaxies at z=1.5 using IRAM PdBI observations of the CO[2-1], CO[3-2] and CO[5-4] transitions for 4 galaxies, including VLA observations of CO[1-0] for 3 of them, with the aim of constraining the average state of H2 gas. Exploiting prior knowledge of the velocity range, spatial extent and size of the CO emission we measure reliable line fluxes with S/N>4-7 for individual transitions. While the average CO Spectral Line Energy Distribution (SLED) has a sub-thermal excitation similar to the Milky Way (MW) up to CO[3-2], we show that the average CO[5-4] emission is four times stronger than assuming MW excitation. This demonstrates the presence of an additional component of more excited, denser and possibly warmer molecular gas. The ratio of CO[5-4] to lower-J CO emission is lower than in local (U)LIRGs and high-redshift SMGs, correlating closely with the average intensity of the radiation field and with the star formation surface density, but not with the SF efficiency (SFE). The CO[5-4] luminosity correlates linearly with LIR over 4 orders of magnitudes, with z=1.5 BzK galaxies following the same trend as local spirals and (U)LIRGs and high redshift star bursting SMGs. The CO[5-4] luminosity is thus empirically related to the dense gas, and might be a more convenient way to probe it than standard high--density tracers that are much fainter than CO. We see excitation variations among our sample galaxies, that can be linked to their evolutionary state and clumpiness in optical rest frame images. In one galaxy we see spatially resolved excitation variations, where the more highly excited part of the galaxy corresponds to the location of massive SF clumps. This supports to models that suggest that giant clumps are the main source of the high excitation CO emission in high redshift disk-like galaxies.

description: Hierarchical uncertainty quantification can reduce the computational cost of stochastic circuit simulation by employing spectral methods at different levels. This paper presents an efficient framework to simulate hierarchically some challenging stochastic circuits/systems that include high-dimensional subsystems. Due to the high parameter dimensionality, it is challenging to both extract surrogate models at the low level of the design hierarchy and to handle them in the high-level simulation. In this paper, we develop an efficient ANOVA-based stochastic circuit/MEMS simulator to extract efficiently the surrogate models at the low level. In order to avoid the curse of dimensionality, we employ tensor-train decomposition at the high level to construct the basis functions and Gauss quadrature points. As a demonstration, we verify our algorithm on a stochastic oscillator with four MEMS capacitors and 184 random parameters. This challenging example is simulated efficiently by our simulator at the cost of only 10 minutes in MATLAB on a regular personal computer.

description: Les nourriceries, soutenues par la productivité des zones estuariennes, permettent le renouvellement des populations et en particulier des ressources halieutiques. En estuaire de Seine et dans la baie de Seine orientale, l’étude de la fonctionnalité des habitats de nourriceries s’appuie sur des suivis de poissons en milieux estuariens (DCE) et côtiers (DCSMM) pour calculer des indicateurs du bon état écologique. Les programmes de surveillance de la DCSMM et de la DCE sont distincts mais des similarités dans leurs protocoles, la zone d’échantillonnage et la période de réalisation des campagnes scientifiques suggèrent qu’une mutualisation partielle serait possible. Nous proposons dans ce rapport de mener une réflexion autour des protocoles DCSMM et DCE afin de rationaliser les suivis des communautés de poissons en estuaire de Seine et dans la baie de Seine orientale. Une mutualisation des campagnes DCSMM-DCE permettrait de pérenniser les suivis déjà existants, de valoriser les données déjà acquises et d’étendre la résolution spatiale de l’échantillonnage. Ces connaissances seront indispensables pour mieux comprendre le fonctionnement des écosystèmes et pour produire un indice de bon état écologique commun, incluant les écosystèmes estuariens et côtiers. En plus de l’avantage scientifique, l’harmonisation et la mutualisation des campagnes DCSMM-DCE permettra de limiter les impacts environnementaux résultant des recherches scientifiques et de rationaliser le financement des différentes campagnes par les agences de l’eau.

Blind search for radio-quiet and radio-loud gamma-ray pulsars with Fermi-LAT data

description: The Fermi Large Area Telescope (LAT) has observed more than a hundred of gamma-ray pulsars, about one third of which are radio-quiet, i.e. not detected at radio frequencies. The most of radio-loud pulsars are detected by Fermi LAT by using the radio timing models, while the radio-quiet ones are discovered in a blind search. The difference in the techniques introduces an observational selection bias and, consequently, the direct comparison of populations is complicated. In order to produce an unbiased sample, we perform a blind search of gamma-ray pulsations using Fermi-LAT data alone. No radio data or observations at optical or X-ray frequencies are involved in the search process. We produce a gamma-ray selected catalog of 25 non-recycled gamma-ray pulsars found in a blind search, including 16 radio-quiet and 9 radio-loud pulsars. This results in the direct measurement of the fraction of radio-quiet pulsars $\varepsilon_{RQ} = 64\pm 10\%$, which is in agreement with the existing estimates from the population modeling in the outer magnetosphere model. The Polar cap models are disfavored due to a lower expected fraction and the prediction of age dependence. The age, gamma-ray energy flux, spin-down luminosity and sky location distributions of the radio-loud and radio-quiet pulsars from the catalog do not demonstrate any statistically significant difference. The results indicate that the radio-quiet and radio-loud pulsars belong to one and the same population. The catalog shows no evidence for the radio beam evolution.

description: We work entirely in the smooth category. An embedding $f:(S^2\times S^1)\sqcup S^3\rightarrow {\mathbb R}^6$ is {\it Brunnian}, if the restriction of $f$ to each component is isotopic to the standard embedding. For each triple of integers $k,m,n$ such that $m\equiv n \pmod{2}$, we explicitly construct a Brunnian embedding $f_{k,m,n}:(S^2\times S^1)\sqcup S^3 \rightarrow {\mathbb R}^6$ such that the following theorem holds. Theorem: Any Brunnian embedding $f:(S^2\times S^1)\sqcup S^3\rightarrow {\mathbb R}^6$ is isotopic to $f_{k,m,n}$ for some integers $k,m,n$ such that $m\equiv n \pmod{2}$. Two embeddings $f_{k,m,n}$ and $f_{k',m',n'}$ are isotopic if and only if $k=k'$, $m\equiv m' \pmod{2k}$ and $n\equiv n' \pmod{2k}$. We use Haefliger's classification of embeddings $S^3\sqcup S^3\rightarrow {\mathbb R}^6$ in our proof. The following corollary shows that the relation between the embeddings $(S^2\times S^1)\sqcup S^3\rightarrow {\mathbb R}^6$ and $S^3\sqcup S^3\rightarrow {\mathbb R}^6$ is not trivial. Corollary: There exist embeddings $f:(S^2\times S^1)\sqcup S^3\rightarrow {\mathbb R}^6$ and $g,g':S^3\sqcup S^3\rightarrow {\mathbb R}^6$ such that the componentwise embedded connected sum $f\#g$ is isotopic to $f\#g'$ but $g$ is not isotopic to $g'$.

Etat des masses d'eau

description: Dans le cadre de la DCE, un état des lieux de la qualité des masses d'eau de La Réunion est réalisé pour chaque cycle de gestion de 6 ans, et validé par le Comité de l'eau et de la Biodiversité. L'évaluation de l'état des masses d'eau est basée sur les grilles de qualité DCE locales et repose sur les données acquises par les suivis du Réseau de Contrôle de Surveillance et validées. Afin de suivre régulièrement l'évolution de la qualité des masses d'eau, pendant les 6 ans du plan de gestion, des estimations de l'état sont produites annuellement et diffusées sur l'atlas interactif DCE. Une fiche pour chacune des 12 masses d'eau de La Réunion synthétise les résultats pour les différents éléments de qualité et apporte des précisions sur l'évaluation. Le présent rapport regroupe les 12 fiches "masses d'eau" établies selon les données acquises jusqu'au 31/12/2021. Ce bilan, basé sur les critères DCE 2000/60/CE, est réalisé à partir des derniers résultats validés. Il ne se substitue pas à l'état des lieux officiel des masses d'eau disponible en ligne sur le site du Comité de Bassin de La Réunion.
