description: N-body codes to perform simulations of the origin and evolution of the Large Scale Structure of the Universe have improved significantly over the past decade both in terms of the resolution achieved and of reduction of the CPU time. However, state-of-the-art N-body codes hardly allow one to deal with particle numbers larger than a few 10^7, even on the largest parallel systems. In order to allow simulations with larger resolution, we have first re-considered the grouping strategy as described in Barnes (1990) (hereafter B90) and applied it with some modifications to our WDSH-PT (Work and Data SHaring - Parallel Tree) code. In the first part of this paper we will give a short description of the code adopting the Barnes and Hut algorithm \cite{barh86} (hereafter BH), and in particular of the memory and work distribution strategy applied to describe the {\it data distribution} on a CC-NUMA machine like the CRAY-T3E system. In the second part of the paper we describe the modification to the Barnes grouping strategy we have devised to improve the performance of the WDSH-PT code. We will use the property that nearby particles have similar interaction list. This idea has been checked in B90, where an interaction list is builded which applies everywhere within a cell C_{group} containing a little number of particles N_{crit}. B90 reuses this interaction list for each particle $ p \in C_{group}$ in the cell in turn. We will assume each particle p to have the same interaction list. Thus it has been possible to reduce the CPU time increasing the performances. This leads us to run simulations with a large number of particles (N ~ 10^7/10^9) in non-prohibitive times.

Kaon Absorption from Kaonic Atoms and Formation Spectra of Kaonic Nuclei

description: We considered the kaon absorption from atomic states into nucleus. We found that the nuclear density probed by the atomic kaon significantly depends on the kaon orbit. Then, we reexamined the meanings of the observed strengths of one-body and two-body kaon absorption, and investigated the effects to the formation spectra of kaon bound states by in-flight ($K^-,p$) reactions. As a natural consequence, if the atomic kaon probes the smaller nuclear density, the ratio of the two-body absorption at nuclear center is larger than the observed value, and the depth of the imaginary potential is deeper even at smaller kaon energies as in kaonic nuclear states because of the large phase space for the two-body processes.

description: Multilateral and private sector organizations in international development and industrial policy have increasingly been investing into the governance of extractive industries in recent decades. This manifests in a series of accountability mechanisms through which implementing and financing institutions commit themselves to transnational minimum standards. However, mediating between these abstract standards and their concrete implementation proofs to be problematic. We trace this problem by investigating accountability mechanisms in practice. We show how mining companies and international development banks outsource their accountability obligations to third parties, and how these entities mediate between abstract standards and implementation. We argue that the implementation of standards is paradoxically undermined by the proliferation of these mediating entities; a finding we explain referring to studies on transnational bureaucratic rule. In this paper we first introduce our understanding of mediation as bureaucratic practice in an internationalized order of rule. We then show how the mining company AngloGold Ashanti and the International Finance Corporation externalize accountability through mediation.
title: The assessment of the spawning-stock biomass of sprat in the Gotland Basin (Eastern Baltic Sea) with the Hensen - Apstein method with some innovations

description: No abstracts are to be cited without prior reference to the author.Spawning-stock biomass of sprat (Sprattus sprattus balticus Schneider) has been calculated with the seasonal production method for the year 2005 from 6 ichthyoplankton surveys performed in the Gotland Basin from April to August. The temperature of ambient water and thus the duration of the developmental stages were determined with the help of empirical model of vertical distribution of sprat eggs. Mortality rates were computed in a new way: these indices were calculated from the total amounts of sprat eggs on stages 1 and 2 in the investigated area. That amount was taken from the maps of distribution of eggs. This method allowed taking into account the drift of eggs during their incubation, and also avoiding the influence of the irregularities in the distribution of sampling positions. After the calculation of mortality rates we could draw the maps of horizontal distribution of daily production of sprat eggs on the 1st stage, and then calculated the seasonal production, which gave the number of spawning females in the investigated area. Fecundity of fishes was defined dependently on their mean weight in the spawning-stock for the year. The obtained result matched very well with the assessment from hydroacoustic surveys performed in May 2005. Also the assessment of spawning-stock biomass of sprat has been made based on the results of one ichthyoplankton survey in the peak of spawning season, when nearly all adult fishes must have been spawning. The assessment made by daily production method went out to be higher than the assessment made by the seasonal production method.

description: The metasurface concept has emerged as an advantageous reconfigurable antenna architecture for beam forming and wavefront shaping, with applications that include satellite and terrestrial communications, radar, imaging, and wireless power transfer. The metasurface antenna consists of an array of metamaterial elements distributed over an electrically large structure, each subwavelength in dimension and with subwavelength separation between elements. In the antenna configuration we consider here, the metasurface is excited by the fields from an attached waveguide. Each metamaterial element can be modeled as a polarizable dipole that couples the waveguide mode to radiation modes. Distinct from the phased array and electronically scanned antenna (ESA) architectures, a dynamic metasurface antenna does not require active phase shifters and amplifiers, but rather achieves reconfigurability by shifting the resonance frequency of each individual metamaterial element. Here we derive the basic properties of a one-dimensional waveguide-fed metasurface antenna in the approximation that the metamaterial elements do not perturb the waveguide mode and are non-interacting. We derive analytical approximations for the array factors of the 1D antenna, including the effective polarizabilities needed for amplitude-only, phase-only, and binary constraints. Using full-wave numerical simulations, we confirm the analysis, modeling waveguides with slots or complementary metamaterial elements patterned into one of the surfaces.

description: Two metal coordination polymers, namely {[Co(MIBA)2]·2H2O}n (SNUT-3) and {[Cu(MIBA)2]·2H2O}n (SNUT-4), where HMIBA = 4-(1H-2-methylimidazol-1-yl)benzoic acid, were prepared by hydrothermal methods. Single-crystal X-ray analysis revealed that the structure of SNUT-3 exhibits a 3D→3D fourfold interpenetrating structure with diamondoid frameworks, while SNUT-4 shows a 2D + 2D → 3D inclined polycatenation structure. The gas adsorption property of SNUT-3 and photocatalytic activity of SNUT-4 for the degradation of Rhodamine B has been explored.

description: We suggest that generalized parton distributions can be probed in charged current meson production process, $ep\toν_{e}π^{-}p$. In contrast to pion photoproduction, this process is sensitive to the unpolarized GPDs $H,\,E$, and for this reason has a very small contamination by higher twist and Bethe-Heitler type contributions. Since all produced hadrons are charged, we expect that the kinematics of this process could be easily reconstructed. We estimated the cross-sections in the kinematics of upgraded 12 GeV Jefferson Laboratory experiments and found that thanks to large luminosity the process can be measured with reasonable statistics.

description: We consider the current fluctuations in a mesoscopic circuit consisting of nodes connected by arbitrary connectors, in a setup with multiple normal or superconducting terminals. In the limit of weak superconducting proximity effect, simplified equations for the second-order cross-correlators can be derived from the general counting field theory, and the result coincides with the semiclassical principle of minimal correlations. We discuss the derivation of this result in a multi-dot case.

description: The fractional Laplacian in R^d has multiple equivalent characterizations. Moreover, in bounded domains, boundary conditions must be incorporated in these characterizations in mathematically distinct ways, and there is currently no consensus in the literature as to which definition of the fractional Laplacian in bounded domains is most appropriate for a given application. The Riesz (or integral) definition, for example, admits a nonlocal boundary condition, where the value of a function u(x) must be prescribed on the entire exterior of the domain in order to compute its fractional Laplacian. In contrast, the spectral definition requires only the standard local boundary condition. These differences, among others, lead us to ask the question: "What is the fractional Laplacian?" We compare several commonly used definitions of the fractional Laplacian (the Riesz, spectral, directional, and horizon-based nonlocal definitions), and we use a joint theoretical and computational approach to examining their different characteristics by studying solutions of related fractional Poisson equations formulated on bounded domains. In this work, we provide new numerical methods as well as a self-contained discussion of state-of-the-art methods for discretizing the fractional Laplacian, and we present new results on the differences in features, regularity, and boundary behaviors of solutions to equations posed with these different definitions. We present stochastic interpretations and demonstrate the equivalence between some recent formulations. Through our efforts, we aim to further engage the research community in open problems and assist practitioners in identifying the most appropriate definition and computational approach to use for their mathematical models in addressing anomalous transport in diverse applications.

description: The finite reorient-time of swimmers leads to a finite run length $\ell$ and the kinetic accumulation boundary layer on the microscopic length scale $δ$ on a non-penetrating wall. That boundary layer is the microscopic origin of the swim pressure, and is impacted by the geometry of the boundary [Yan \& Brady, \textit{J. Fluid. Mech.}, 2015, \textbf{785}, R1]. In this work we extend the analysis to analytically solve the boundary layer on an arbitrary-shaped body distorted by the local mean curvature. The solution gives the swim pressure distribution and the total force (torque) on an arbitrarily shaped body immersed in swimmers, with a general scaling of the curvature effect $Π^{swim}\simλδ^2/L$.

Finally, a characterization of the shape derivative as a solution of a modified transmission problem is given.

description: The habitability of the exoplanet has a strong dependence on the stellar activity of the host star. M-dwarf stars constitute a large fraction of the stellar population, therefore they are of primary interest in searching potentially habitable exoplanets. It is easier to detect planets around low-mass stars since they have effectively smaller radii and low temperatures due to which we can easily detect planet transits. The stellar flares from the host star may play a crucial role in triggering prebiotic chemistry on the exoplanet, whereas large frequency flares and CMEs would lead to atmospheric erosion and ozone depletion. The stellar flares sometimes are associated with Coronal Mass Ejections, which may directly impact the exoplanetary atmospheres and affect habitability. Here, we present a case - study of the flaring activity of an M-dwarf star and its impact on its orbiting exoplanet in the habitable zone. We utilized the light-curve data from TESS. We used the AltaiPony python-based package to identify flares. We further analyze and quantify the flare activity to understand its possible impact on the exoplanet environment around the habitable zone.

description: No abstracts are to be cited without prior reference to the author.The mainstream ICES stock assessment methods were evaluated in their conceptual ability to provide quantitative measures of uncertainty about variables of management interest. Probability statements generated about future of the stock were found to be conceptually inconsistent with the statistical methods used. The Bayesian approach to statistical inference is recommended to substitute the current uncertainty methods in order to achieve consistent probability statements about the consequences of alternative management actions.

Calculations of properties of the largest fragment resulting from multifragmentation are rare. In this paper we compute these properties and compare them with the data for the case of gold on carbon. We use the canonical thermodynamic model. The model also gives a bimodal distribution for the largest fragment in a narrow energy range.

description: In this article we study an almost $f$-cosymplectic manifold admitting a Ricci soliton. We first prove that there do not exist Ricci solitons on an almost cosymplectic $(κ,μ)$-manifold. Further, we consider an almost $f$-cosymplectic manifold admitting a Ricci soliton whose potential vector field is the Reeb vector field and show that a three dimesional almost $f$-cosymplectic is a cosymplectic manifold. Finally we classify a three dimensional $η$-Einstein almost $f$-cosymplectic manifold admitting a Ricci soliton.

description: While it is well-known that the standard integral operator K of (stationary) diffuse-gray radiation, as it occurs in the radiosity equation, is compact if the domain of radiative interaction is sufficiently regular, we show noncompactness of the operator if the domain is polyhedral. We also show that a stationary operator is never compact when reinterpreted in a transient setting. Moreover, we provide new proofs, which do not use the compactness of K, for 1 being a simple eigenvalue of K for connected enclosures, and for I-(1-e)K being invertible, provided the emissivity e does not vanish identically.

description: A comprehensive study of impurity-induced magnetism in nonmagnetically (Mg${}^{2+}$) and magnetically (Co${}^{2+}$) doped PbNi${}_{2}$V${}_{2}$O${}_{8}$ compounds is given, using both macroscopic dc susceptibility and local-probe electron spin resonance (ESR) techniques. Magnetic coupling between impurity-liberated spins is estimated from a linewidth of low-temperature ESR signal in Mg-doped samples. In addition, in the case of magnetic cobalt dopants the impurity-host magnetic exchange is evaluated from the Co-induced contribution to the linewidth in the paramagnetic phase. The experimentally observed severe broadening of the ESR lines in the magnetically doped compounds with respect to nonmagnetic doping is attributed to a rapid spin-lattice relaxation of the Co${}^{2+}$ ions, which results in a bottleneck-type of temperature dependence of the induced linewidth. The exchange parameters obtained from the ESR analysis offer a satisfactory explanation of the observed low-temperature magnetization in doped samples.

description: No abstracts are to be cited without prior reference to the author.Research fisheries surveys are now implemented as monitoring programs of fish stocks and provide a large set of measurements on the evolution of their state. Here we show how fishery-independent diagnostics of fish stocks can be achieved using a comprehensive set of indices and analysis procedures inspired from environmental monitoring. We present fish stock indices, analysis procedures and diagnostics results for nine stocks in European waters. The set of indices considered comprises two population abundance indices, four indices for population vital traits and nine indices for spatial organisation by age. The indices are combined and selected using multivariate techniques that maximise correlation between variables and also continuity in time. Trend detection and quality control techniques are then applied on the time series of the combined and selected indices. Based on these analyses diagnostic tables are filled, leading to comprehensive indicator-based diagnostics of fish stocks. Similar analysis procedures are applied to all case studies and results are reported using standardised templates. The application to a wide range of fish stocks in different health conditions with different behaviours and past histories demonstrates the potential of the tools and indices for delivering diagnostics in operational mode. The paper is intended to be a manual summarising the results of the EU-project Fisboat (Fishery-independent survey-based operational assessment tools) for general use outside the project.

description: It is a general belief that the only possible way to consistently deform the Pauli-Fierz action, changing also the gauge algebra, is general relativity. Here we show that a different type of deformation exists in three dimensions if one allows for PT non-invariant terms. The new gauge algebra is different from that of diffeomorphisms. Furthermore, this deformation can be generalized to the case of a collection of massless spin-two fields. In this case it describes a consistent interaction among them.

description: A large family of words must contain two words that are similar. We investigate several problems where the measure of similarity is the length of a common subsequence. We construct a family of n 1/3 permutations on n letters, such that LCS of any two of them is only cn1/3 , improving a construction of Beame, Blais, and Huynh-Ngoc. We relate the problem of constructing many permutations with small LCS to the twin word problem of Axenovich, Person and Puzynina. In particular, we show that every word of length n over a k-letter alphabet contains two disjoint equal subsequences of length cnk−2/3 . Connections to other extremal questions on common subsequences are exhibited. Many problems are left open.

description: In this article, we present new ideas concerning Non-Gaussian Component Analysis (NGCA). We use the structural assumption that a high-dimensional random vector $vX$ can be represented as a sum of two components - a low-dimensional signal $vS$ and a noise component $vN$. We show that this assumption enables us for a special representation for the density function of $vX$. Similar facts are proven in original papers about NGCA, but our representation differs from the previous versions. The new form helps us to provide a strong theoretical support for the algorithm; moreover, it gives some ideas about new approaches in multidimensional statistical analysis. In this paper, we establish important results for the NGCA procedure using the new representation, and show benefits of our method.

description: Let $B_i^{(k)}$ be the $k$-uniform hypergraph whose vertex set is of the form $S\cup T$, where $|S|=i$, $|T|=k-1$, and $S\cap T=\emptyset$, and whose edges are the $k$-subsets of $S\cup T$ that contain either $S$ or $T$. We derive upper and lower bounds for the Turán density of $B_i^{(k)}$ that are close to each other as $k\to\infty$. We also obtain asymptotically tight bounds for the Turán density of several other infinite families of hypergraphs. The constructions that imply the lower bounds are derived from elementary number theory by probabilistic arguments, and the upper bounds follow from some results of de Caen, Sidorenko, and Keevash.
Two-dimensional anisotropic Heisenberg antiferromagnet in a field

description: The classical, square lattice, uniaxially anisotropic Heisenberg antiferromagnet in a magnetic field parallel to the easy axis is studied using Monte Carlo techniques. The model displays a long-range ordered antiferromagnetic, an algebraically ordered spin-flop, and a paramagnetic phase. The simulations indicate that a narrow disordered phase intervenes between the ordered phases down to quite low temperatures. Results are compared to previous, partially conflicting findings on related classical models as well as the quantum variant with spin S=1/2.

Pointlike Hopf defects in Abelian projections
Creators: name: Bruckmann, Falk
Publisher: name: arXiv
Year: 2000
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We present a new kind of defect in Abelian Projections, stemming from pointlike zeros of second order. The corresponding topological quantity is the Hopf invariant pi_3(S^2) (rather than the winding number pi_2(S^2) for magnetic monopoles). We give a visualisation of this quantity and discuss the simplest non-trivial example, the Hopf map. Such defects occur in the Laplacian Abelian gauge in a non-trivial instanton sector. For general Abelian projections we show how an ensemble of Hopf defects accounts for the instanton number.

description: The 3rd EGRET Catalog of High-energy Gamma-ray Sources contains 170 unidentified sources, and there is great interest in the nature of these sources. One means of determining source class is the study of flux variability on time scales of days; pulsars are believed to be stable on these time scales while blazars are known to be highly variable. In addition, previous work has demonstrated that 3EG J0241-6103 and 3EG J1837-0606 are candidates for a new gamma-ray source class. These sources near the Galactic plane display transient behavior but cannot be associated with any known blazars. Although many instances of flaring AGN have been reported, the EGRET database has not been systematically searched for occurrences of short-timescale ($\sim1$ day) variability. These considerations have led us to conduct a systematic search for short-term variability in EGRET data, covering all viewing periods through proposal cycle 4. Six 3EG catalog sources are reported here to display variability on short time scales; four of them are unidentified. In addition, three non-catalog variable sources are discussed.

Modeling interactions of photons with pseudoscalar and vector mesons

description: We model interaction of photons, pseudoscalars and vector mesons within the resonance chiral symmetric theory with the SU(3) breaking. The couplings of the model are fitted to the experimental data. Within the developed model we predict the light-by-light contributions to the muon anomalous magnetic moment $a_μ^P = (82.8 \pm 3.4)\times 10^{-11}$. The error covers also the model dependence within the class of models considered in this paper. The model was implemented into the Monte Carlo event generator Ekhara to simulate the reactions $e^+e^-\to e^+e^- P$, $P=π^0,η,η'$ and into the Monte Carlo event generator Phokhara to simulate the reactions $e^+e^-\to Pγ(γ)$.

description: We analyze a quantum dot strongly coupled to the conducting leads via quantum point contacts - Fano regime of transport - and report a variety of resonant states which demonstrate the dominance of the interacting resonances in the scattering process in a low confining potential. There are resonant states similar to the eigenstates of the isolated dot, whose widths increase with increasing the coupling strength to the environment, and hybrid resonant states. The last ones are approximatively obtained as a linear combination of eigenstates with the same parity in the lateral direction, and the corresponding resonances show the phenomena of resonance trapping or level repulsion. The existence of the hybrid modes suggests that the open quantum dot behaves in the Fano regime like an artificial molecule.

description: A method for the calculation of translationally invariant wave functions for systems of identical fermions with arbitrary potential of pair interaction is developed. It is based on the well-known result that the essential dynamic part of the Hamiltonian for the system of identical particles is the Reduced Hamiltonian operator describing relative movement of two particles inside the system. The eigenfunctions of this operator take into account all correlations caused by interaction. These eigenfunctions are basic for the construction of the components (i.e. the functions with a lower degree of antisymmetry) of the system wave functions. The main problem of this approach appears to be antisymmetrization of the components. The developed universal algorithm for antisymmetrization gives a possibility to perform this operation in a simple way and keep numerical approximations under control.

description: We consider the problem of traveling among random points in Euclidean space, when only a random fraction of the pairs are joined by traversable connections. In particular, we show a threshold for a pair of points to be connected by a geodesic of length arbitrarily close to their Euclidean distance, and analyze the minimum length Traveling Salesperson Tour, extending the Beardwood-Halton-Hammersley theorem to this setting.

description: This article investigates the properties of the global attractor of hyperbolic balance laws on the circle, given by : u_t+f(u)_x=g(u). The new tool of sub-attractors is introduced. They contain all solutions on the global attractor up to a given number of zeros. The article proves finite dimensionality of all sub-attractors, provides a full parameterization of all sub-attractors and derives a system of ODEs for the embedding parameters that describes the full PDE dynamics on the sub-attractor.

description: Based on the initial state geometrical symmetry for collisions between two identical heavy ions at high energy, the general form for the one- and two-particle azimuthal distributions is deduced. Relation between these distributions and the usual flow parameters is discussed. New measures for the azimuthal correlations are suggested. Some numerical results on the values of the measures are shown from an event generator for Au+Au collisions with different colliding centralities at 200 GeV.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: A simple and commonly used method to approximate the total claim distribution of a (possible weakly dependent) insurance collective is the normal approximation. In this article, we investigate the error made when the normal approximation is plugged in a fairly general distribution-invariant risk measure. We focus on the rate of the convergence of the error relative to the number of clients, we specify the relative error's asymptotic distribution, and we illustrate our results by means of a numerical example. Regarding the risk measure, we take into account distortion risk measures as well as distribution-invariant coherent risk measures.
