The effects of deformation parameter on thermal width of moving quarkonia in plasma

In general we can say that the thermal width of quarkonia corresponds to imaginary part of it’s potential. Gravity dual of theories give explicit form of potential as V Q Q ¯ $$ {V}_{{}_{Q\overline{Q}}} $$ . Since there is an explicit formula for Im V Q Q ¯ $$ {V}_{{}_{Q\overline{Q}}} $$ one can consider different gravity duals and study the results of contribution of various parameters. Variable gravity duals of moving pair in plasma have different results for potential. Our paper shows that defor-mation parameter c in warp factor leads to new results that we present them for arbitrary angles of the pair with respect to it’s velocity. We compare our results with the case that no deformation parameter is in metric background. We will see that the thermal width of the pair increases with increasing deformation parameter. Also, for nonzero values of de-formation parameter the pair feels moving plasma in all distances. In addition our results indicate that contribution of deformation parameter leads to larger dissociation length for the moving pair reverse to the effect of the pair’s velocity in the plasma
Turbulent strings in AdS/CFT

We study nonlinear dynamics of the flux tube between an external quark-antiquark pair in N = 4 $$ +AFw-mathcal{N} = 4 $$ super Yang-Mills theory using the AdS/CFT duality. In the gravity side, the flux tube is realized by a fundamental string whose endpoints are attached to the AdS boundary. We perturb the endpoints in various ways and numerically compute the time evolution of the nonlinearly oscillating string. As a result, cusps can form on the string, accompanied by weak turbulence and power law behavior in the energy spectrum. When cusps traveling on the string reach the boundary, we observe the divergence of the force between the quark and antiquark. Minimal amplitude of the perturbation below which cusps do not form is also investigated. No cusp formation is found when the string moves in all four AdS space directions, and in this case an inverse energy cascade follows a direct cascade
Exact SU(5) Yukawa matrix unification in the general flavour violating MSSM

We investigate the possibility of satisfying the SU(5) boundary condition Y d = Y eT at the GUT scale within the renormalizable R -parity conserving Minimal Supersymmetric Standard Model (MSSM). Working in the super-CKM basis, we consider non-zero flavour off-diagonal entries in the soft SUSY-breaking mass matrices and the A -terms. At the same time, the diagonal A -terms are assumed to be suppressed by the respective Yukawa couplings. We show that a non-trivial flavour structure of the soft SUSY-breaking sector can contribute to achieving precise Yukawa coupling unification for all three families, and that the relevant flavour-violating parameters are m d ˜ 2 23 $$ \left({m}_{\tilde{d}}^2\right)23 $$ , m d ˜ 2 12 $$ \left({m}_{\tilde{d}}^2\right)12 $$ , m d ˜ 2 13 $$ \left({m}_{\tilde{d}}^2\right)13 $$ and A 12/21 d . We indicate the parameter space regions where the Yukawa unification condition can be satisfied, and we demonstrate that it is consistent with a wide set of experimental constraints, including flavour and electroweak observables, Higgs physics and the LHC bounds. However, as a consequence of the down-electron Yukawa unification requirement, the MSSM vacuum in our scenario is metastable, though long-lived. We also point out that the lightest neutralino needs to be almost purely bino-like and relatively light, with the mass in the ballpark of 250 GeV. Since the proper value of the dark matter relic density is in this case obtained through co-annihilation with a sneutrino, at least one generation of sleptons must be light. Such a clear experimental prediction makes the flavour-violating SU(5) Yukawa unification scenario fully testable at the LHC s = 14 $$ \sqrt{s}=14 $$ TeV with the 3-lepton searches for electroweakino production
Thermoelectric DC conductivities with momentum dissipation from higher derivative gravity

We present a mechanism of momentum relaxation in higher derivative gravity by adding linear scalar fields to the Gauss-Bonnet theory. We analytically computed all of the DC thermoelectric conductivities in this theory by adopting the method given by Donos and Gauntlett in [ arXiv:1406.4742 ]. The results show that the DC electric conductivity is not a monotonic function of the effective impurity parameter β : in the small β limit, the DC conductivity is dominated by the coherent phase, while for larger β , pair creation contribution to the conductivity becomes dominant, signaling an incoherent phase. In addition, the DC heat conductivity is found independent of the Gauss-Bonnet coupling constant
Localization and mass spectra of various matter fields on scalar-tensor brane

Recently, a new scalar-tensor braneworld model was presented   in [Phys. Rev. D 86 (2012) 127502]. It not only solves the   gauge hierarchy problem but also reproduces a correct Friedmann-like   equation on the brane.  In this new model, there are two different   brane solutions, for which the mass spectra of gravity on the brane   are the same.  In this paper, we investigate localization and mass   spectra of various bulk matter fields (i.e., scalar, vector,   Kalb-Ramond, and fermion fields) on the brane. It is shown that the   zero modes of all the matter fields can be localized on the positive   tension brane under some conditions, and the mass spectra of each   kind of bulk matter field for the two brane solutions are different   except for some special cases, which implies that the two brane   solutions are not physically equivalent. When the coupling constants   between the dilaton and bulk matter fields take special values, the   mass spectra for both solutions are the same, and the scalar and   vector zero modes are localized on the negative tension brane, while   the KR zero mode is still localized on the positive tension brane
The Higgs legacy of the LHC Run I

Based on Run I data we present a comprehensive analysis of Higgs couplings. For the first time this SFitter analysis includes independent tests of the Higgs-gluon and top Yukawa couplings, Higgs decays to invisible particles, and off-shell Higgs measurements. The observed Higgs boson is fully consistent with the Standard Model, both in terms of coupling modifications and effective field theory. Based only on Higgs total rates the results using both approaches are essentially equivalent, with the exception of strong correlations in the parameter space induced by effective operators. These correlations can be controlled through additional experimental input, namely kinematic distributions. Including kinematic distributions the typical Run I reach for weakly interacting new physics now reaches 300 to 500 GeV
What are Clusters in High Dimensions and are they Difficult to Find?

The distribution of distances between points in a high-dimensional data set tends to look quite different from the distribution of the distances in a low-dimensional data set. Concentration of norm is one of the phenomena from which high-dimensional data sets can suffer. It means that in high dimensions – under certain general assumptions – the relative distances from any point to its closest and farthest neighbour tend to be almost identical. Since cluster analysis is usually based on distances, such effects must be taken into account and their influence on cluster analysis needs to be considered. This paper investigates consequences that the special properties of high-dimensional data have for cluster analysis. We discuss questions like when clustering in high dimensions is meaningful at all, can the clusters just be artifacts and what are the algorithmic problems for clustering methods in high dimensions
Liquid-gas phase transition in nuclear matter from realistic many-body approaches

The existence of a liquid-gas phase transition for hot nuclear systems at subsaturation densities is a well-established prediction of finite-temperature nuclear many-body theory. In this paper, we discuss for the first time the properties of such a phase transition for homogeneous nuclear matter within the self-consistent Green's function approach. We find a substantial decrease of the critical temperature with respect to the Brueckner-Hartree-Fock approximation. Even within the same approximation, the use of two different realistic nucleon-nucleon interactions gives rise to large differences in the properties of the critical point
Toxicity Assessment of Contaminated Soils from a Mining Area in Northeast Italy by Using Lipid Peroxidation Assay.

Contamination by heavy metals in soils may strongly affect the environmental quality. Lipid peroxidation
caused by heavy metals in plants was investigated as a relevant bioassay of toxicity. Soils and wild plants
(dandelion and willow) were collected from an abandoned mine area in northeast Italy, and the concentration
of different heavy metals (Ni, Cr, Cu, Pb, Zn, Fe and Mn) were measured and analyzed. Soils affected by
mining activities presented total Zn, Cu, and Pb concentrations (2566, 3975, 20,815 mg kg−1 respectively)
above toxic thresholds, and 58% for Fe. Heavy metal-induced oxidative stress was evidenced by the generation
of reactive radicals, followed by an increase in malondialdehyde (MDA) production up to 41.64 μM in
willow leaves. We found that MDA concentration in plant tissues differed significantly among species and
plant organs. The higher concentration of metal in soil corresponded with the higher concentration of
MDA in the plant. The combined results of metal concentration, MDA content and translocation coefficients
in plants show that the investigated plants are rather highly tolerant towards environmental pollution.
This suggests that they could be useful in phytoremediation of metal contaminated sites
Tethered Monte Carlo: computing the effective potential without critical slowing down

We present Tethered Monte Carlo, a simple, general purpose method of computing the effective potential of the order parameter (Helmholtz free energy). This formalism is based on a new statistical ensemble, closely related to the micromagnetic one, but with an extended configuration space (through Creutz-like demons). Canonical averages for arbitrary values of the external magnetic field are computed without additional simulations. The method is put to work in the two-dimensional Ising model, where the existence of exact results enables us to perform high precision checks. A rather peculiar feature of our implementation, which employs a local Metropolis algorithm, is the total absence, within errors, of critical slowing down for magnetic observables. Indeed, high accuracy results are presented for lattices as large as L = 1024
Comparison of charged particle identification using pulse shape discrimination and ΔE−E methods between front and rear side injection in silicon detectors

The response of silicon-silicon-CsI(Tl) telescopes, developed within the FAZIA collaboration, to fragments produced in nuclear reactions 84Kr+120-124Sn at 35 A MeV, has been used to study ion identification methods. Two techniques are considered for the identification of the nuclear products in the silicon stages. The standard ΔE−E one requires signals induced in two detection layers by ions punching through the first one. Conversely, the digital Pulse Shape Analysis (PSA) allows the identification of ions stopped in the first silicon layer. The capabilities of these two identification methods have been compared for different mountings of the silicons, i.e. rear (particles entering through the low electric field side) or front (particles entering through the high electric field side) side injection. The ΔE−E identification method gives exactly the same results in both configurations. At variance, the pulse shape discrimination is very sensitive to the detector mounting. In case of rear side injection, the identification with the "energy vs. charge rise time" PSA method presents energy thresholds which are significantly lower than in the case of front side injection
Limit Behavior of the Multi-Agent Rotor-Router System

International audiencehe rotor-router model, also called the Propp machine, was introduced as a deterministic alternative to the random walk. In this model, a group of identical tokens are initially placed at nodes of the graph. Each node maintains a cyclic ordering of the outgoing arcs, and during consecutive turns the tokens are propagated along arcs chosen according to this ordering in round-robin fashion. The behavior of the model is fully deterministic. Yanovski et al.(2003) proved that a single rotor-router walk on any graph with m edges and diameter D stabilizes to a traversal of an Eulerian circuit on the set of all 2m directed arcs on the edge set of the graph, and that such periodic behaviour of the system is achieved after an initial transient phase of at most 2mD steps.The case of multiple parallel rotor-routers was studied experimentally, leading Yanovski et al. to the experimental observation that a system of k > 1 parallel walks also stabilizes with a period of length at most 2m steps. In this work we disprove this observation, showing that the period of parallel rotor-router walks can in fact, be superpolynomial in the size of graph. On the positive side, we provide a characterization of the periodic behavior of parallel router walks, in terms of a structural property of stable states called a subcycle decomposition. This property provides us the tools to efficiently detect whether a given system configuration corresponds to the transient or to the limit behavior of the system. Moreover, we provide polynomial upper bounds of O(m^4D^2 + mD log k) and O(m^5k^2) on the number of steps it takes for the system to stabilize. Thus, we are able to predict any future behavior of the system using an algorithm that takes polynomial time and space. In addition, we show that there exists a separation between the stabilization time of the single-walk and multiple-walk rotor-router systems, and that for some graphs the latter can be asymptotically larger even for the case of k = 2 walks
Hepatocellular adenoma displaying a HNF1alpha inactivation in a patient with familial adenomatous polyposis coli.

Patients with familial adenomatous polyposis coli (FAP) may rarely develop hepatocellular adenoma. Here we report the case of a 37-year-old FAP woman presenting a hepatocellular adenoma after oestroprogestative oral contraception use. In this steatotic adenoma, we identified an inactivating biallelic mutation of HNF1alpha. In addition to the known germline APC mutation Q1062fs, we did not find an inactivation of the second APC allele nor an activation of the beta-catenin target genes GLUL and GPR49. Our findings contrast with two hepatocellular adenoma cases related to FAP, for which a biallelic inactivation of the APC gene was previously described. Altogether, these results suggest that benign hepatocellular carcinogenesis may be dependent on or independent of the Wnt/beta-catenin pathway in patients with FAP
International representations of Balkan wars: a socio-anthropological account in international relations perspective

International audienceThis article introduces the socio-anthropological concept of international representations to examine the relationship between a civilizational rhetoric, the West European and the international politics of otherization and containment of Southeast Europe, and an essentialist and timeless bias in international relations theory, including both radical and constructivist trends. We first explore the different narrative perspectives on the Balkan wars from the beginning to the end of twentieth century. Their subsequent problematization is aimed at challenging the way how they have constructed commonplace and time-worn representations, which international society shares with different consequences in international affairs. This is a limited conception since international representations as a socio-anthropological concept are always socially, culturally and politically constructed, contested and negotiated. They do not neutrally refer to a reality in the world; they create a reality of their own. Moreover, this limited conception ignores the fact that how, by whom and in whose interest international representations are constructed is itself a form of power in international relations. Therefore, the way international representations are constructed can be problematized as an example of political and ideological projects that operate in the West as well as in the Southeast European countries that are the object of Western foreign policy
Commissioning of the ATLAS detector and combined beam test results

A paraître dans NIMThe ATLAS detector is a large and complex experiment. Commissioning of the various components, both separately and together, is a challenging task which requires a methodology and a sustained and detailed plan of work. The commissioning stages of ATLAS will be described, together with an overview of results obtained during the construction and the integration so far. Once installed and functional the various parts of the detectors are operated with cosmic particles in several combinations. The performance of the detector components, both individually and in combination, has been also measured in a series of test beam data taken over the last years
Policing the internal Schengen borders – managing the double bind between free movement and migration control

International audienceAnalyses of security practices at borders have focused on the dematerialisation and de-territorialisation of control of individuals’ mobility. This paper explores the nature of the control the state still exercises over individuals’ mobility at national borders. It focuses on a border that is supposed to have been opened, between France and Italy, inside the Schengen Area. It is based on analysis of the practices, representations and organisation of French border police officers, beginning with the legal and organisational transformations due to implementation of the Schengen Convention at the France–Italy border. It then turns to the study of border police officers’ targeting practices, using Heyman's notion of a ‘plausible story’. Finally, it assesses the influence of deportation practices on the territoriality of the control of individuals’ mobility, as well as its effects on targeting practices. These borders are at the core of the interaction between the construction of a new, European political centre, and the affirmation of an older one, the national, political centre. This paper demonstrates that border police officers are in charge of dealing with the tension, a double bind of sorts, emerging from this interaction. National, internal borders are still a site in which the state manages individuals’ mobility
Public risk perception of relaxation of transmissible spongiform encephalopathies (tse) measures in Europe

The authors thank the members of the "NeuroPrion Risk Control Group" for various comments and helpful hints. They also thank all of the interviewees who contributed information and enabled this study. Last but not least, the authors are grateful for many invaluable comments provided by three reviewers of a previous version of this article.International audienceThe so-called "TSE roadmap" was published by the European Commission on July 15, 2005. The transmissible spongiform encephalopathy (TSE) roadmap suggests relaxation of bovine spongiform encephalopathy (BSE) in cattle and other animal transmissible spongiform encephalopathies measures in the short, medium, and long term. According to the TSE roadmap, "Any relaxation of BSE measures following the scientific assessment should be initiated by an open discussion with all stakeholders and supported by a strong communication strategy" (European Commission 2005, 5). Bearing this in mind, a social scientific project as designed to (1) involve different stakeholder groups, governmental risk managers, and their scientific advisors and (2) obtain their perception of the TSE roadmap and of its implications for precautionary consumer protection in five European Union (EU) Member States. This study describes the risk perception and risk management of TSE in Europe as exemplified by the TSE roadmap. The following query guided the international comparative study: How is TSE risk perceived by four interviewed stakeholder groups in five studied countries? The risk perceptions of TSE of risk managers from the ministries in charge in Belgium, France, Germany, Italy, and the United Kingdom, as well as their scientific advisors and stakeholder groups, were determined. The stakeholder groups were from three different areas involved with TSE, including farmers, consumers, and the meat/food industry. The issue to be addressed is roadmapping an adequate instrument for stakeholder involvement and for risk decision making
REJUVENATING NANOCLUSTERS WITH 'SLEEPING ANCHORS': PRE-ADAPTATION AND LIFE CYCLE

Working paper serie RMT (WPS 10-11) , 28 p.International audienceThis article investigates how anchor firms sustain high tech clusters rejuvenation by means of technological pre-adaptation. Based on evidences are drawn from the comparison of the evolution of two nano-electronics clusters, i.e., Grenoble (France) and Catania (Italy) clusters which are sharing the same anchor tenant firm STMicroelectronics. Cluster rejuvenation comes from pre-adaptation of actors (scientific and technological diversity), competition amongst anchor tenant firms, competition and overlap amongst networks and the mobilization of sleeping anchors tenant organizations to renew actors and technologies. As soon as the process of specialization (asset specificity, network specificity, technology speciation) starts, it is important to stimulate pre-adaptation to avoid lock-in of the cluster on one technological trajector
Sustainable agriculture as a central science to solve global society issues

Serious global issues such as poverty, illness, food prices, climate changes, global market, pollution, pest adaptation and resistance, soil degradation, decreasing biodiversity and desertiﬁcation can be explained by the increasing artiﬁcialization of human society. Since most issues are now intertwined they cannot be solved anymore by the classical ﬁreman approach. In that respect, the structure of actual science and governmental institutions are probably outdated and should evolve to meet global challenges. Unexpectedly, agronomy appears as a central science to solve current societal issues because agronomists are trained to manage the input of many disciplines such as plant biology, soil science, climate sciences, ecology and chemistry
Generating a condensed representation for association rules

International audienceAssociation rule extraction from operational datasets often produces several tens of thousands, and even millions, of association rules. Moreover, many of these rules are redundant and thus useless. Using a semantic based on the closure of the Galois connection, we define a condensed representation for association rules. This representation is characterized by frequent closed itemsets and their generators. It contains the non-redundant association rules having minimal antecedent and maximal consequent, called min-max association rules. We think that these rules are the most relevant since they are the most general non-redundant association rules. Furthermore, this representation is a basis, i.e., a generating set for all association rules, their supports and their confidences, and all of them can be retrieved needless accessing the data. We introduce algorithms for extracting this basis and for reconstructing all association rules. Results of experiments carried out on real datasets show the usefulness of this approach. In order to generate this basis when an algorithm for extracting frequent itemsets—such as Apriori for instance—is used, we also present an algorithm for deriving frequent closed itemsets and their generators from frequent itemsets without using the dataset
