Application of the MST clustering to the high energy gamma-ray sky. III - New detections of gamma-ray emission from blazars

We present the results of a photon cluster search in the gamma-ray sky observed by the Fermi Large Area Telescope, using the new Pass 8 dataset, at energies higher than 10 GeV. By means of the Minimum Spanning Tree (MST) algorithm, we found 25 clusters associated with catalogued blazars not previously known as gamma-ray emitters. The properties of these sources are discussed.Comment: 10 pages, 3 figures. Accepted for publication in Astrophysics & Space Scienc

Application of the MST clustering to the high energy gamma-ray sky. I - New possible detection of high-energy gamma-ray emission associated with BL Lac objects

In this paper we show an application of the Minimum Spanning Tree (MST) clustering method to the high-energy gamma-ray sky observed at energies higher than 10 GeV in 6.3 years by the Fermi-Large Area Telescope. We report the detection of 19 new high-energy gamma-ray clusters with good selection parameters whose centroid coordinates were found matching the positions of known BL Lac objects in the 5th Edition of the Roma-BZCAT catalogue. A brief summary of the properties of these sources is presented.Comment: 11 pages, 7 figures. Accepted for publication in Astrophysics & Space Scienc

A new flaring high energy gamma-ray source

We report the detection of a new gamma-ray source in the Fermi-LAT sky using a source detection tool based on the Minimal Spanning Tree algorithm. The source, not reported in previous LAT catalogues but very recently observed in the X-rays and optical bands, is characterized by an increasing gamma-ray activity in 2012 June-September, reaching a weekly peak flux of (3.3+-0.6)*10^-7 photons cm^-2 s^-1. A search for a possible counterpart provides indication that it can be associated with the radio source NVSS J141828+354250 whose optical SDSS colours are typical of a blazar.Comment: 4 pages, 3 figures.

Minimum Spanning Tree cluster analysis of the LMC region above 10 GeV: detection of the SNRs N 49B and N 63A

We present the results of a cluster search in the gamma-ray sky images of the Large Magellanic Cloud region by means of the Minimum Spanning Tree algorithm at energies higher than 10 GeV, using 9 years of Fermi-LAT data. Several significant clusters were found, the majority of which associated with previously known gamma-ray sources. New significant clusters associated with the supernova remnants N 49B and N 63A are also found, and confirmed with a Maximum Likelihood analysis of the Fermi-LAT data.Comment: 11 pages, 3 figures.

A MST catalogue of γ-ray source candidates above 10 GeV and at Galactic latitudes higher than 20°

We describe a catalogue of γ-ray source candidates selected using the minimum spanning tree (MST) algorithm on the nine year Fermi-LAT sky (Pass 8) at energies higher than 10 GeV. The extragalactic sky at absolute Galactic latitudes above 20° has been investigated using rather restrictive selection criteria, resulting in a total sample of 1342 sources. Of these, 249 are new detections that have not been previously associated with γ-ray catalogues. A large portion of these candidates have interesting counterparts, which are most likely blazars. In this paper, we report the main results of the catalogue selection and search of counterparts. The catalogue is only available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (ftp://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/619/A2

Douleurs et travail : aider le patient à garder un emploi

Introduction.— A significant part of the workers suffer from musculoskeletal pain (back pain,upper limb). Some of them are at risk to ose their job due to their health condition. Objective. — The aim of the article is to describe synthetically what actors and measure can be used in order to help a patient keep his/her job in spite of the pain. Results.— First place measures include a visit with the occupational physician before work resumption, part-time return to work and workplace accommodation.Second place measures require that a professional project is built by the patient supported by a knowledgeable person. These measures depend on the funding agency.They are devoted to compensate the work disability situation, and/or to provide the training required by the patient’s project. Discussion and conclusion. — Work disability prevention faces many challenges due to barriers between the stakeholders, scattering of the knowledge and the complexity of legislative issues.However, it remains possible provided the patient is committed and supported by a case manager in charge of coordinating the information and the stakeholders. Confidence and collaboration are key issues in the process.

Two new high-energy γ-ray blazar candidates

We report the detection of two new γ-ray sources in the Fermi-Large Area Telescope sky (Pass 8) at energies higher than 20 GeV and confirmed at lower energies, using a source detection tool based on the Minimum Spanning Tree algorithm. One of these sources, at a Galactic latitude of about -4°, is a new discovery, while the other was previously reported above 50 GeV in the 2FHL catalogue. We searched for archival multiwavelength data of possible counterparts and found interesting candidates. Both objects are radio sources and their Wide-field Infrared Survey Explorer infrared colours are typical of blazars. While, for the former source, no optical spectra are available, for the latter, a puzzling optical spectrum corresponding to a white dwarf star is found in the 6dF data base. We discuss the spectral energy distributions of both sources and possible interpretations

Polos regionais de desenvolvimento do esporte e do lazer: a descentralização da gestão de uma Política de Estado

La implementación del Polo en la UPF es de extrema importancia para el desarrollo regional, permitiendo las políticas públicas de una forma descentralizada y articulada. Se compone de 151 municipios distribuidos en seis micro-regiones correspondientes a las Coordinadoras Regionales de Educación: 7ª, 9ª, 15ª, 20ª, 25ª y 39ª CRE. El polo actúa en sintonía con FUNDERGS como facilitador de acciones, estimulando el desarrollo deportivo en la región e incentivando nuevas alternativas y propuestas volcadas en el deporte y el ocio. En el caso de los municipios de su región, se cuenta con la infraestructura existente en sus dependencias en los diversos eventos propuestos por FUNDERGS y municipios de su región, recibiendo, interpretando, diagnosticando y ayudando a los gestores municipales en sus demandas, siendo el principal interlocutor del Estado. En los dos años de instalación, varias fueron las acciones propuestas por FUNDERGS y desarrolladas por el polo, teniendo públicos y variados objetivos.The implementation of the Pole at UPF is extremely important for regional development, allowing public policies in a decentralized and articulated way.

An ecological method for the sampling of nonverbal signalling behaviours of young children with profound and multiple learning disabilities (PMLD)

- Background: Profound and multiple learning disabilities (PMLD) are a complex range of disabilities that affect the general health and wellbeing of the individual and their capacity to interact and learn. - Method: We developed a new methodology to capture the nonsymbolic signalling behaviours of children with PMLD within the context of a face-to-face interaction with a caregiver to provide analysis at a micro-level of descriptive detail incorporating the use of the ELAN digital video software. - Conclusion: The signalling behaviours of participants in a natural, everyday interaction can be better understood with the use of this innovation in methodology, which is predicated on the ecology of communication. Recognition of the developmental ability of the participants is an integral factor within that ecology. The method presented establishes an advanced account of the modalities through which a child affected by PMLD is able to communicate

Advances in Human-Robot Handshaking

The use of social, anthropomorphic robots to support humans in various industries has been on the rise. During Human-Robot Interaction (HRI), physically interactive non-verbal behaviour is key for more natural interactions. Handshaking is one such natural interaction used commonly in many social contexts. It is one of the first non-verbal interactions which takes place and should, therefore, be part of the repertoire of a social robot. In this paper, we explore the existing state of Human-Robot Handshaking and discuss possible ways forward for such physically interactive behaviours.Comment: Accepted at The 12th International Conference on Social Robotics (ICSR 2020) 12 Pages, 1 Figur
