The Lepton Flavour Violating Higgs Decays at the HL-LHC and the ILC

Run-I results from the CMS collaboration show an excess of events in the
decay $h \to \mu \tau_e$ with a local significances of 2.4$\sigma$. This could
be the first hint of flavour violation in the Higgs sector. We summarise the
bounds on the flavour violating Yukawa couplings from direct searches, low
energy measurements and projected future experiments. We discuss the
sensitivity of upcoming HL-LHC runs and future lepton colliders in measuring
lepton-flavour violating couplings using an effective field theory framework.
For the HL-LHC we find limits on BR($h\to \mu \tau$) and BR$(h\to e \tau)
\lesssim \mathcal{O}(0.5)\%$ and on BR($h \to e \mu) \lesssim
\mathcal{O}(0.02)\%$. For an ILC with center-of-mass energy of 1 TeV we expect
BR($h \to e \tau$) and BR($h\to \mu \tau$) to be measurable down to
$\mathcal{O}(0.2)\%$.Comment: 27 pages, 1 figure and 13 tables; v2 : Minor corrections, conclusions

Search for supersymmetry in pp collisions at sqrt(s) = 13 TeV in the
  single-lepton final state using the sum of masses of large-radius jets

Results are reported from a search for supersymmetric particles in
proton-proton collisions in the final state with a single, high transverse
momentum lepton; multiple jets, including at least one b-tagged jet; and large
missing transverse momentum. The data sample corresponds to an integrated
luminosity of 2.3 inverse femtobarns at sqrt(s) = 13 TeV, recorded by the CMS
experiment at the LHC. The search focuses on processes leading to high jet
multiplicities, such as gluino pair production with gluinos to t t-bar
neutralino[1]. The quantity M[J], defined as the sum of the masses of the
large-radius jets in the event, is used in conjunction with other kinematic
variables to provide discrimination between signal and background and as a key
part of the background estimation method. The observed event yields in the
signal regions in data are consistent with those expected for standard model
backgrounds, estimated from control regions in data. Exclusion limits are
obtained for a simplified model corresponding to gluino pair production with
three-body decays into top quarks and neutralinos. Gluinos with a mass below
1600 GeV are excluded at a 95% confidence level for scenarios with low
neutralino[1] mass, and neutralinos with a mass below 800 GeV are excluded for
a gluino mass of about 1300 GeV. For models with two-body gluino decays
producing on-shell top squarks, the excluded region is only weakly sensitive to
the top squark mass.Comment: Replaced with published version. Added the journal reference and DOI.

Multiwavelength study of the fast rotating supergiant high-mass X-ray
  binary IGR J16465-4507

Since its launch, the X-ray and gamma-ray observatory INTEGRAL satellite has
revealed a new class of high-mass X-ray binaries (HMXB) displaying fast flares
and hosting supergiant companion stars. Optical and infrared (OIR) observations
in a multi-wavelength context are essential to understand the nature and
evolution of these newly discovered celestial objects. The goal of this
multiwavelength study (from ultraviolet to infrared) is to characterise the
properties of IGR J16465-4507, to confirm its HMXB nature and that it hosts a
supergiant star. We analysed all OIR, photometric and spectroscopic
observations taken on this source, carried out at ESO facilities. Using
spectroscopic data, we constrained the spectral type of the companion star
between B0.5 and B1 Ib, settling the debate on the true nature of this source.
We measured a high rotation velocity of v = 320 +/- 8 km/s from fitting
absorption and emission lines in a stellar spectral model. We then built a
spectral energy distribution from photometric observations to evaluate the
origin of the different components radiating at each energy range. We finally
show that, having accurately determined the spectral type of the early-B
supergiant in IGR J16465-4507, we firmly support its classification as an
intermediate supergiant fast X-ray transient (SFXT).Comment: A&A in press, 14 pages, 15 tables, 13 figure
Determinants of contractor satistaction

Performance in the construction industry is increasingly scrutinized as a result of the delays, cost overruns
and poor quality of the industry's products and services. Increasingly, disputes, conflicts and mismatches of
objectives among participants are contributory factors. Performance measurement approaches have been
developed to overcome these problems. However, these approaches focus primarily on objective measures to
the exclusion of subjective measures, particularly those concerning contractor satisfaction (Co-S). The contractor
satisfaction model (CoSMo) developed here is intended to rectify the situation. Data derived from a questionnaire survey of 75 large contractors in Malaysia in respect of a key project are analysed to identify
participant factors and their strength of relationship with Co-S dimensions. The results are presented in the
form of eight regression equations. The outcome is a tool for use by project participants to provide a better
understanding of how they, and the project, affect contractor satisfaction. The developed model sheds some
light on a hitherto unknown aspect of construction management in providing an increased awareness of the
importance of major Malaysian construction contractors' needs in the execution of successful projects
Annual maximum daily rainfall trends in the Midwest, southeast and southern Brazil in the last 71 years.

The aim of this study was to model, based on the overall distribution of extreme values, the probability of occurrence of a particular level of annual maximum daily rainfall in three Brazilian regions (Midwest, Southeast and South) and study their behavior over the past 71 years. The parameters of the general distribution of extreme values were estimated by the maximum likelihood method. The Mann-Kendall test showed that there is a positive trend in the annual maximum daily rainfall data series. The non-stationarity was rejected by the augmented Dickey-Fuller test supporting the use of the density function of extreme value distribution to describe the values of the occurrence of annual maximum daily rainfall. The Kolmogorov?Smirnov/Lilliefors goodness-of-fit test showed the good fit of the studied variable to the probability distribution function. The Midwest region has a return period of more frequent annual maximum daily rainfall below 300 mm in comparison with other regions. There is a clear change in the behavior of this extreme event in the Southern region. According to the literature, in past decades annual maximum daily rainfall of 248 mm has been estimated for a return period of 100 years for the state of Santa Catarina-South region, while the results found with the current series, annual maximum daily rainfall of 250 mm was estimated for a return period of 10 years. Extreme annual maximum daily rainfalls for return periods smaller were also found in other regions.201
Abelian Chern-Simons vortices and holomorphic Burgers hierarchy

We consider the Abelian Chern-Simons gauge field theory in 2+1 dimensions and its relation to the holomorphic Burgers hierarchy. We show that the relation between the complex potential and the complex gauge field as in incompressible and irrotational hydrodynamics has the meaning of the analytic Cole-Hopf transformation, linearizing the Burgers hierarchy and transforming it into the holomorphic Schrödinger hierarchy. The motion of planar vortices in Chern-Simons theory, which appear as pole singularities of the gauge field, then corresponds to the motion of zeros of the hierarchy. We use boost transformations of the complex Galilei group of the hierarchy to construct a rich set of exact solutions describing the integrable dynamics of planar vortices and vortex lattices in terms of generalized Kampe de Feriet and Hermite polynomials. We apply the results to the holomorphic reduction of the Ishimori model and the corresponding hierarchy, describing the dynamics of magnetic vortices and the corresponding lattices in terms of complexified Calogero-Moser models. We find corrections (in terms of Airy functions) to the two-vortex dynamics from the Moyal space-time noncommutativity
On some Challenges for Online Trust and Reputation Systems

<p>The Internet form a globally distributed network that provides a ubiquitous medium for interaction, the exchange of ideas, and commerce. The web is pervading our everyday lives in ways that were unimaginable even ten years ago. The evolving use of the web requires robust and efficient trust and reputation management mechanisms. During the past decade, online trust and reputation systems have provided cogent answers to emerging challenges in the global computing infrastructures relating to computer and network security, electronic commerce, virtual enterprises, social networks and cloud computing. The goal of these systems in such global computing infrastructures is to allow entities to reason about the trustworthiness of other entities and to make autonomous decisions on the basis of trust. This requires the development of computational trust models that enable entities to reason about trust and to verify the properties of a particular interaction. The robustness of these mechanisms, which is one of the critical factors for the success of this technology, is currently not being sufficiently addressed. The global computing infrastructure is highly dynamic with continuously appearing and disappearing entities and services. It is vital that the associated computational trust model is able to incorporate this dynamism and that equally flexible legislative and regulatory frameworks emerge. In this thesis, we present an overview of the characteristics of the existing characteristics of the existing online trust and reputation models and systems through a multidimensional framework, which can serve as a basis to understand the current state of the art in the area. The critical open challenges that limit the effectiveness of today’s trust and reputation systems are discussed by providing a comprehensive literature review. Furthermore, we present a set of our contributions as a way to address some of these challenges and propose prospectives for online trust and reputation systems.</p>PhD i informasjonsteknologiPhD in Information Technolog
Characterization of the expression of the hypoxia-induced genes neuritin, TXNIP and IGFBP3 in cancer.

International audienceBy triggering an adaptive response to hypoxia which is a common feature of tumor microenvironments, endothelial cells contribute to the onset of angiogenic responses involved in tumor growth. Therefore, identifying hypoxic markers represent a challenge for a better understanding of tumor angiogenesis and for the optimization of anti-angiogenic therapeutic strategy. Using representational difference analysis combined with microarray, we here report the identification of 133 hypoxia-induced transcripts in human microendothelial cells (HMEC-1). By Northern blot, we confirm hypoxia-induced expression of insulin-like growth factor binding protein 3 (igfbp3), thioredoxin-interacting protein (txnip), neuritin (nrn1). Finally, by performing in situ hybridization on several types of human tumors, we provide evidence for nrn1 and txnip as hypoxic perinecrotic markers and for igfbp3 as a tumor endothelial marker. We propose these hypoxia-induced genes could represent relevant prognostic tools and targets for therapeutic intervention in cancers
Landau-Ginzburg Limit of Black Hole's Quantum Portrait: Self Similarity
  and Critical Exponent

Recently we have suggested that the microscopic quantum description of a
black hole is an overpacked self-sustained Bose-condensate of N
weakly-interacting soft gravitons, which obeys the rules of 't Hooft's large-N
physics. In this note we derive an effective Landau-Ginzburg Lagrangian for the
condensate and show that it becomes an exact description in a semi-classical
limit that serves as the black hole analog of 't Hooft's planar limit. The role
of a weakly-coupled Landau-Ginzburg order parameter is played by N. This
description consistently reproduces the known properties of black holes in
semi-classical limit. Hawking radiation, as the quantum depletion of the
condensate, is described by the slow-roll of the field N. In the semiclassical
limit, where black holes of arbitrarily small size are allowed, the equation of
depletion is self similar leading to a scaling law for the black hole size with
critical exponent 1/3.Comment: 7 pages, late
Resolutions, higher extensions and the relative Mal'tsev axiom

We study how the concept of higher-dimensional extension which comes from
categorical Galois theory relates to simplicial resolutions. For instance, an
augmented simplicial object is a resolution if and only if its truncation in
every dimension gives a higher extension, in which sense resolutions are
infinite-dimensional extensions or higher extensions are finite-dimensional
resolutions. We also relate certain stability conditions of extensions to the
Kan property for simplicial objects. This gives a new proof of the fact that a
regular category is Mal'tsev if and only if every simplicial object is Kan,
using a relative setting of extensions.Comment: Dedicated to James Gray and Tamar Janelidze on the occasion of their

Which fundamental constants for cosmic microwave background and baryon-acoustic oscillation?

International audienceWe use the three-scale framework of Hu et al. to show how the cosmic microwave background (CMB) anisotropy spectrum depends on the fundamental constants. As expected, the spectrum depends only on dimensionless combinations of the constants, and we emphasize the points that make this generally true for cosmological observables. Our analysis suggests that the CMB spectrum shape is mostly determined by α2me/mp and by mp/mχ, the proton-CDM-particle mass ratio. The distance to the last-scattering surface depends on Gmpmχ/ ħc, so published CMB observational limits on time variations of the constants implicitly assume the time independence of this quantity, as well as a flat-ΛCDM  cosmological model. On the other hand, low-redshift baryon-acoustic oscillation, H0, and baryon-mass-fraction measurements can be combined with the shape of the CMB spectrum to give information that is largely independent of these assumptions. In particular, we show that the pre-recombination values of Gm2χ/ħc, mp/mχ, and α2me/mp are equal to their present values at a precision of ~15%
Complete list of Darboux integrable chains of the form t1x = tx +d (t, t1)

Cataloged from PDF version of article.We study differential-difference equation (d/dx) t (n+1,x) =f (t (n,x),t (n+1,x), (d/dx) t (n,x)) with unknown t (n,x) depending on continuous and discrete variables x and n. Equation of such kind is called Darboux integrable, if there exist two functions F and I of a finite number of arguments x, { t (n+k,x) } k=-∞ ∞, {(dk /d xk) t (n,x) } k=1 ∞, such that Dx F=0 and DI=I, where D x is the operator of total differentiation with respect to x and D is the shift operator: Dp (n) =p (n+1). Reformulation of Darboux integrability in terms of finiteness of two characteristic Lie algebras gives an effective tool for classification of integrable equations. The complete list of Darboux integrable equations is given in the case when the function f is of the special form f (u,v,w) =w+g (u,v). © 2009 American Institute of Physics
Issues with phase space characterization of laser-plasma generated\ud
electron beams

Plasma acceleration is the new frontier in particle beam accelerators. Using the strong electric fields inside a plasma it is possible to\ud
achieve accelerating gradients orders of magnitude larger with respect to current technologies. Different schemes, using completely\ud
different approaches, have been proposed and several already tested, producing beams of energy up to several GeV. Regardless of\ud
the technique used for acceleration a precise determination of the output beam parameters is mandatory for the fine tuning of the\ud
process. The measurement of these parameters, in particular the beam distribution in transverse and longitudinal phase space, is\ud
not trivial, mainly due to the large energy spread and to the tight focusing of these beams or to the background noise produced in\ud
the plasma channel. We illustrate the main problems related to the diagnostic of this kind of beams and some of the proposed or\ud
already realized solution
18-Fluoro-2-deoxyglucose positron emission tomography-computed tomography: an additional tool in the diagnosis of prosthetic valve endocarditis.

Abstract\ud
OBJECTIVES:\ud
To evaluate the role of 18-fluoro-2-deoxyglucose positron emission tomography-computed tomography ((18)F-FDG-PET-CT) in the diagnosis of infectious endocarditis (IE).\ud
METHODS:\ud
We retrospectively examined 27 consecutive patients who were admitted to the Infectious Diseases Department of Tor Vergata University Hospital between 2009 and 2013 with a suspicion of IE. The final IE diagnosis was defined according to the modified Duke criteria, and the microbiological and diagnostic results were collected for each patient.\ud
RESULTS:\ud
Twenty out of 27 patients had a suspected prosthetic valve endocarditis (PVE) and seven had a suspected native valve endocarditis (NVE). Twenty-five out of 27 patients (92%) had a confirmed diagnosis of IE (18/25 PVE and 7/25 NVE); 16 had a positive echocardiography evaluation and 16 had positive (18)F-FDG-PET-CT findings. Echocardiography showed a higher sensitivity as a diagnostic tool for the detection of IE compared to (18)F-FDG-PET-CT (80% vs. 55%). However, a greater number of PVE had positive (18)F-FDG-PET-CT results compared to those with positive echocardiography findings (11/13 vs. 9/13), and overall 89% (16/18) of confirmed PVE resulted (18)F-FDG-PET-CT positive. Analyzing only the cases who underwent transoesophageal echocardiography, (18)F-FDG-PET-CT showed a sensitivity of 85% in PVE (vs. 69% for echocardiography and 77% for the Duke criteria). All seven patients with NVE had a positive echocardiography and negative (18)F-FDG-PET-CT findings (p<0.001).\ud
CONCLUSIONS:\ud
The results of this study further highlight the limitations of echocardiography in the diagnosis of PVE and the potential advantages of (18)F-FDG-PET-CT in these cases
Local and global stability for Lotka-Volterra systems with distributed delays and instantaneous negative feedbacks

This paper addresses the local and global stability of n-dimensional Lotka-Volterra systems
with distributed delays and instantaneous negative feedbacks. Necessary and sufficient conditions for local stability independent of the choice of the delay functions are given, by imposing a weak nondelayed diagonal dominance which cancels the delayed competition effect. The global asymptotic
stability of positive equilibria is established under conditions slightly stronger than the ones
required for the linear stability. For the case of monotone interactions, however, sharper conditions are presented. This paper generalizes known results for discrete delays to systems with distributed delays. Several applications illustrate the results.Portugal-FEDERFundação para a Ciência e a Tecnologia (FCT) - programa POCI, projecto PDCT/

Late Palaeogene emplacement and late Neogene-Quaternary exhumation of the Kuril island-arc root (Kunashir island) constrained by multi-method thermochronometry

The Kuril islands constitute a volcanic island arc-trench system, stretching from eastern Hokkaido (Japan) to Kamchatka (Russia) along the northwestern Pacific subduction system. The current arc consists of several volcanic islands mainly with Neogene basement and capped by several, predominantly andesitic, active subduction stratovolcanoes. Kunashir Island is the southwestern-most island of the arc, just off the Hokkaido coast and represents the study area in this paper. The island is composed of a Lower Complex of mainly late Miocene to Pliocene volcanic rocks, covered by an Upper Complex of younger (basaltic) andesitic lava flows and tuffs on which currently four active volcanic edifices are built. In the Lower Complex sub-volcanic and deeper-seated intrusives of the so-called Prasolov and Dokuchaev magmatic complexes are found. More differentiated, tonalitic-granodioritic rocks were collected from these small intrusive bodies. An early Oligocene zircon LA-ICP-MS U/Pb age of 31 Ma for the Prasolov Complex was obtained, showing that the basement of Kunashir Island is older than previously thought. Thermochronometry (apatite fission-track and U-Th-Sm/He and zircon U-Th/He analyses) further shows that the magmatic basement of the island was rapidly exhumed in the Pleistocene to present levels in a differential pattern, with He-ages ranging from 1.9 to 0.8 Ma. It is shown that the northern section of the island was hereby exhumed more intensely. (C) 2015, China University of Geosciences (Beijing) and Peking Universit
Doctor–patient differences in risk and time preferences: a field experiment

We conduct a framed field experiment among patients and doctors to test whether the two groups have similar risk and time preferences. We elicit risk and time preferences using multiple price list tests and their adaptations to the healthcare context. Risk and time preferences are compared in terms of switching points in the tests and the structurally estimated behavioural parameters. We find that doctors and patients significantly differ in their time preferences: doctors discount future outcomes less heavily than patients. We find no evidence that doctors and patients systematically differ in their risk preferences in the healthcare domain
The internationalisation of higher education in Brazil: analysis of a Spanish-Brazilian scientific cooperation project in CAL.

Over the past few years, the internationalisation of Higher Education has become a priority in Brazilian educational policies. The importance of internationalisation has become apparent thanks to numerous initiatives, ranging from the increase in funding for graduate and postgraduate research stays abroad to projects of scientific cooperation between universities in different countries. In this context, this paper explores a scientific cooperation project developed by two universities in Brazil and Spain: the Universidade Estadual de Campinas (UNICAMP) and the Universitat Politècnica de València (UPV), relating to the field of Computer-Assisted Learning (CAL). First of all, the internationalisation of the Brazilian Higher Education will be discussed, and the different initiatives - such as the Ciência sem Fronteiras (Science without Borders) Programme launched by the Brazilian Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) - will be presented. Following that, the paper will focus on the original proposal for the ongoing cooperation project between the UNICAMP and the UPV and on the results obtained until now. Next, the initiative will be analysed with special attention to the importance and the impact that internationalisation has made on Brazilian higher education. Finally, the authors will further explore the ways in which cooperation projects such as the one dealt with in this paper contribute towards the improvement of education. This improvement is mainly due to factors such as: fostering the integration of Information and Communications Technologies (ICT) into teaching-learning practices; investing in teacher training in their home countries and abroad; and encouraging the development of high-quality multimedia materials and authoring tolos
