Authors: Martin-Sanchez Fernando J. , Lopez-Campos Guillermo H. , Almalki Manal , Merolli Mark , Gray Kathleen 
Published: October 2016

SummaryObjectives: The availability of internet-connected mobile, wearable and ambient consumer technologies, direct-to-consumer e-services and peer-to-peer social media sites far outstrips evidence about the efficiency, effectiveness and efficacy of using them in healthcare applications. The aim of this paper is to describe one approach to build a program of health informatics research, so as to generate rich and robust evidence about health data and information processing in self-quantification and associated healthcare and health outcomes.Methods: The paper summarises relevant health informatics research approaches in the literature and presents an example of developing a program of research in the Health and Biomedical Informatics Centre (HaBIC) at the University of Melbourne. The paper describes this program in terms of research infrastructure, conceptual models, research design, research reporting and knowledge sharing.Results: The paper identifies key outcomes from integrative and multiple-angle approaches to investigating the management of information and data generated by use of this Centre’s collection of wearable, mobiles and other devices in health self-monitoring experiments. These research results offer lessons for consumers, developers, clinical practitioners and biomedical and health informatics researchers.Conclusions: Health informatics is increasingly called upon to make sense of emerging self-quantification and other digital health phenomena that are well beyond the conventions of healthcare in which the field of informatics originated and consolidated. To make a substantial contribution to optimise the aims, processes and outcomes of health self-quantification needs further work at scale in multi-centre collaborations for this Centre and for health informatics researchers generally.
Technology in Rehabilitation: Evaluating the Single Leg Squat Exercise with Wearable Inertial Measurement Units

Published: October 2016

SummaryBackground: The single leg squat (SLS) is a common lower limb rehabilitation exercise. It is also frequently used as an evaluative exercise to screen for an increased risk of lower limb injury. To date athlete/patient SLS technique has been assessed using expensive laboratory equipment or subjective clinical judgement; both of which are not without shortcomings. Inertial measurement units (IMUs) may offer a low cost solution for the objective evaluation of athlete/patient SLS technique.Objectives: The aims of this study were to determine if in combination or in isolation IMUs positioned on the lumbar spine, thigh and shank are capable of: (a) distinguishing between acceptable and aberrant SLS technique; (b) identifying specific deviations from acceptable SLS technique.Methods: Eighty-three healthy volunteers participated (60 males, 23 females, age: 24.68 +/− 4.91 years, height: 1.75 +/− 0.09 m, body mass: 76.01 +/− 13.29 kg). All participants performed 10 SLSs on their left leg. IMUs were positioned on participants’ lumbar spine, left shank and left thigh. These were utilized to record tri-axial accelerometer, gyroscope and magnetometer data during all repetitions of the SLS. SLS technique was labelled by a Chartered Physiotherapist using an evaluation framework. Features were extracted from the labelled sensor data. These features were used to train and evaluate a variety of random-forests classifiers that assessed SLS technique.Results: A three IMU system was moderately successful in detecting the overall quality of SLS performance (77% accuracy, 77% sensitivity and 78% specificity). A single IMU worn on the shank can complete the same analysis with 76% accuracy, 75% sensitivity and 76% specificity. Single sensors also produce competitive classification scores relative to multi-sensor systems in identifying specific deviations from acceptable SLS technique.Conclusions: A single IMU positioned on the shank can differentiate between acceptable and aberrant SLS technique with moderate levels of accuracy. It can also capably identify specific deviations from optimal SLS performance. IMUs may offer a low cost solution for the objective evaluation of SLS performance. Additionally, the classifiers described may provide useful input to an exercise biofeed-back application.

ABSTRACT
We present a mass–luminosity relation (MLR) for red dwarfs spanning a range of masses from 0.62

to the end of the stellar main sequence at 0.08

. The relation is based on 47 stars for which dynamical masses have been determined, primarily using astrometric data from Fine Guidance Sensors (FGS) 3 and 1r, white-light interferometers on the Hubble Space Telescope (HST), and radial velocity data from McDonald Observatory. For our HST/FGS sample of 15 binaries, component mass errors range from 0.4% to 4.0% with a median error of 1.8%. With these and masses from other sources, we construct a V-band MLR for the lower main sequence with 47 stars and a K-band MLR with 45 stars with fit residuals half of those of the V band. We use GJ 831 AB as an example, obtaining an absolute trigonometric parallax, π
abs = 125.3 ± 0.3 mas, with orbital elements yielding

and

. The mass precision rivals that derived for eclipsing binaries. A remaining major task is the interpretation of the intrinsic cosmic scatter in the observed MLR for low-mass stars in terms of physical effects. In the meantime, useful mass values can be estimated from the MLR for the ubiquitous red dwarfs that account for 75% of all stars, with applications ranging from the characterization of exoplanet host stars to the contribution of red dwarfs to the mass of the universe.
FROM NEUTRON STAR OBSERVABLES TO THE EQUATION OF STATE. I. AN OPTIMAL PARAMETRIZATION
Authors: Raithel Carolyn A. , Özel Feryal , Psaltis Dimitrios 
Published: October 2016

ABSTRACT
The increasing number and precision of measurements of neutron star masses, radii, and, in the near future, moments of inertia offer the possibility of precisely determining the neutron star equation of state (EOS). One way to facilitate the mapping of observables to the EOS is through a parametrization of the latter. We present here a generic method for optimizing the parametrization of any physically allowed EOS. We use mock EOS that incorporate physically diverse and extreme behavior to test how well our parametrization reproduces the global properties of the stars, by minimizing the errors in the observables of mass, radius, and the moment of inertia. We find that using piecewise polytropes and sampling the EOS with five fiducial densities between ∼1–8 times the nuclear saturation density results in optimal errors for the smallest number of parameters. Specifically, it recreates the radii of the assumed EOS to within less than 0.5 km for the extreme mock EOS and to within less than 0.12 km for 95% of a sample of 42 proposed, physically motivated EOS. Such a parametrization is also able to reproduce the maximum mass to within 0.04

and the moment of inertia of a 1.338

neutron star to within less than 10% for 95% of the proposed sample of EOS.
THE BLOB CONNECTION: SEARCHING FOR LOW CORONAL SIGNATURES OF SOLAR POST-CME BLOBS
Authors: Schanche Nicole E , Reeves Katharine K , Webb David F. 
Published: October 2016

ABSTRACT
Bright linear structures, thought to be indicators of a current sheet (CS), are often seen in Large Angle and Spectrometric Coronagraph (LASCO) on the Solar and Heliospheric Observatory (SOHO) white-light data in the wake of coronal mass ejections (CMEs). In a subset of these post-CME structures, relatively bright blobs are seen moving outward along the rays. These blobs have been interpreted as consequences of the plasmoid instability in the CS, and can help us to understand the dynamics of the reconnection. We examine several instances, taken largely from the SOHO/LASCO CME-rays Catalog, where these blobs are clearly visible in white-light data. Using radially filtered, difference, wavelet enhanced, and multiscale Gaussian normalized images to visually inspect Solar Dynamics Observatory/Atmospheric Imaging Assembly (AIA) data in multiple wavelengths, we look for signatures of material that correspond both temporally and spatially to the later appearance of the blobs in LASCO/C2. Constraints from measurements of the blobs allow us to predict the expected count rates in DN pixel−1 s−1 for each AIA channel. The resulting values would make the blobs bright enough to be detectable at 1.2 R
⊙. However, we do not see conclusive evidence for corresponding blobs in the AIA data in any of the events. We do the same calculation for the “cartwheel CME,” an event in which blobs were seen in X-rays, and find that our estimated count rates are close to those observed. We suggest several possibilities for the absence of the EUV blobs including the formation of the blob higher than the AIA field of view, blob coalescence, and overestimation of blob densities.
FROM EXOPLANETS TO QUASARS: DETECTION OF POTENTIAL DAMPED Lyα ABSORBING GALAXIES USING ANGULAR DIFFERENTIAL IMAGING

ABSTRACT
The advantages of angular differential imaging (ADI) have been previously untested in imaging the host galaxies of damped Lyα (DLA) systems. In this pilot study, we present the first application of ADI to directly image the host galaxy of the DLA seen toward the quasar J1431+3952. K-band imaging of the field surrounding J1431+3952 was obtained on the Gemini North telescope with an adaptive optics system and a laser guide star. We computed a sensitivity curve that demonstrates the sensitivity of our observations as a function of K-band magnitude, impact parameter and DLA angular size. For an impact parameter of 0.″5 (3.4 kpc at the redshift of the absorber) our mass sensitivity is log (M

/M

9.2 and drops to ∼9.0 at separations beyond ∼6 kpc for the smallest size model galaxy. Three candidate galaxies are identified within 5″. Stellar masses were computed from the K-band photometry yielding values of log (M

/M

9.9, 9.7 and 11.1 respectively. The likely identification of the absorbing galaxy is discussed, and we conclude that the galaxy with the largest impact parameter and highest stellar mass is unlikely to be the host, based on its inconsistency with the N(HI) impact parameter relation and inconsistent photometric redshift. While we cannot distinguish between the remaining two candidates as the DLA host, we note that, despite the low spin temperature and relatively high metallicity of the DLA, the host does not appear to be a particularly luminous (high-mass) galaxy.
HIGH-ENERGY ELECTRON IRRADIATION OF INTERSTELLAR CARBONACEOUS DUST ANALOGS: COSMIC-RAY EFFECTS ON THE CARRIERS OF THE 3.4 μm ABSORPTION BAND

Published: October 2016

ABSTRACT
The effects of cosmic rays on the carriers of the interstellar 3.4 μm absorption band have been investigated in the laboratory. This band is attributed to stretching vibrations of CH3 and CH2 in carbonaceous dust. It is widely observed in the diffuse interstellar medium, but disappears in dense clouds. Destruction of CH3 and CH2 by cosmic rays could become relevant in dense clouds, shielded from the external ultraviolet field. For the simulations, samples of hydrogenated amorphous carbon (a-C:H) have been irradiated with 5 keV electrons. The decay of the band intensity versus electron fluence reflects a-C:H dehydrogenation, which is well described by a model assuming that H2 molecules, formed by the recombination of H atoms liberated through CH bond breaking, diffuse out of the sample. The CH bond destruction rates derived from the present experiments are in good accordance with those from previous ion irradiation experiments of HAC. The experimental simplicity of electron bombardment has allowed the use of higher-energy doses than in the ion experiments. The effects of cosmic rays on the aliphatic components of cosmic dust are found to be small. The estimated cosmic-ray destruction times for the 3.4 μm band carriers lie in the 108 yr range and cannot account for the disappearance of this band in dense clouds, which have characteristic lifetimes of 3 × 107 yr. The results invite a more detailed investigation of the mechanisms of CH bond formation and breaking in the intermediate region between diffuse and dense clouds.
THE FORMATION OF A MILKY WAY-SIZED DISK GALAXY. I. A COMPARISON OF NUMERICAL METHODS
Authors: Zhu Qirong , Li Yuexing 
Published: October 2016

ABSTRACT
The long-standing challenge of creating a Milky Way- (MW-) like disk galaxy from cosmological simulations has motivated significant developments in both numerical methods and physical models. We investigate these two fundamental aspects in a new comparison project using a set of cosmological hydrodynamic simulations of an MW-sized galaxy. In this study, we focus on the comparison of two particle-based hydrodynamics methods: an improved smoothed particle hydrodynamics (SPH) code Gadget, and a Lagrangian Meshless Finite-Mass (MFM) code Gizmo. All the simulations in this paper use the same initial conditions and physical models, which include star formation, “energy-driven” outflows, metal-dependent cooling, stellar evolution, and metal enrichment. We find that both numerical schemes produce a late-type galaxy with extended gaseous and stellar disks. However, notable differences are present in a wide range of galaxy properties and their evolution, including star-formation history, gas content, disk structure, and kinematics. Compared to Gizmo, the Gadget simulation produced a larger fraction of cold, dense gas at high redshift which fuels rapid star formation and results in a higher stellar mass by 20% and a lower gas fraction by 10% at z = 0, and the resulting gas disk is smoother and more coherent in rotation due to damping of turbulent motion by the numerical viscosity in SPH, in contrast to the Gizmo simulation, which shows a more prominent spiral structure. Given its better convergence properties and lower computational cost, we argue that the MFM method is a promising alternative to SPH in cosmological hydrodynamic simulations.
A COMPREHENSIVE STUDY OF HYDROGEN ADSORBING TO AMORPHOUS WATER ICE: DEFINING ADSORPTION IN CLASSICAL MOLECULAR DYNAMICS

Published: October 2016

ABSTRACT
Gas–grain and gas–phase reactions dominate the formation of molecules in the interstellar medium (ISM). Gas–grain reactions require a substrate (e.g., a dust or ice grain) on which the reaction is able to occur. The formation of molecular hydrogen (H2) in the ISM is the prototypical example of a gas–grain reaction. In these reactions, an atom of hydrogen will strike a surface, stick to it, and diffuse across it. When it encounters another adsorbed hydrogen atom, the two can react to form molecular hydrogen and then be ejected from the surface by the energy released in the reaction. We perform in-depth classical molecular dynamics simulations of hydrogen atoms interacting with an amorphous water-ice surface. This study focuses on the first step in the formation process; the sticking of the hydrogen atom to the substrate. We find that careful attention must be paid in dealing with the ambiguities in defining a sticking event. The technical definition of a sticking event will affect the computed sticking probabilities and coefficients. Here, using our new definition of a sticking event, we report sticking probabilities and sticking coefficients for nine different incident kinetic energies of hydrogen atoms [5–400 K] across seven different temperatures of dust grains [10–70 K]. We find that probabilities and coefficients vary both as a function of grain temperature and incident kinetic energy over the range of 0.99–0.22.

Published: October 2016

The checklist of Greek Cyanobacteria was created in the framework of the Greek Taxon Information System (GTIS), an initiative of the LifeWatchGreece Research Infrastructure (ESFRI) that has resumed efforts to compile a complete checklist of species reported from Greece. This list was created from exhaustive search of the scientific literature of the last 60 years. All records of taxa known to occur in Greece were taxonomically updated.
The checklist of Greek Cyanobacteria comprises 543 species, classified in 130 genera, 41 families, and 8 orders. The orders Synechococcales and Oscillatoriales have the highest number of species (158 and 153 species, respectively), whereas these two orders along with Nostocales and Chroococcales cover 93% of the known Greek cyanobacteria species. It is worth mentioning that 18 species have been initially described from Greek habitats. The marine epilithic Ammatoidea aegea described from Saronikos Gulf is considered endemic to this area. Our bibliographic review shows that Greece hosts a high diversity of cyanobacteria, suggesting that the Mediterranean area is also a hot spot for microbes.

Biodiversity data is characterized by its cross-disciplinary character, the extremely broad range of data types and structures, and the variety of semantic concepts that it encompasses. Furthermore there is a plethora of different data sources providing resources for the same piece of information in a heterogeneous way. Even if we restrict our attention to Greek biodiversity domain, it is easy to see that biodiversity data remains unconnected and widely distributed among different sources.
To cope with these issues, in the context of the LifeWatch Greece project, i) we supported cataloguing and publishing of all the relevant metadata information of the Greek biodiversity domain, ii) we integrated data from heterogeneous sources by supporting the definitions of appropriate models, iii) we provided means for efficiently discovering biodiversity data of interest and iv) we enabled the answering of complex queries that could not be answered from the individual sources. This work has been exploited, evaluated and scientificaly confirmed by the biodiversity community through the services provided by the LifeWatch Greece portal.
LifeWatchGreece Portal development: architecture, implementation and challenges for a biodiversity research e-infrastructure
Authors: Gougousis Alexandros , Bailly Nicolas 
Published: October 2016

Biodiversity data is characterized by its cross-disciplinary character, the extremely broad range of data types and structures, and the plethora of different data sources providing resources for the same piece of information in a heterogeneous way. Since the web inception two decades ago, there are multiple initiatives to connect, aggregate, share, and publish biodiversity data, and to establish data and work flows in order to analyze them. The European program LifeWatch aims at establishing a distributed network of nodes implementing virtual research environment in Europe to facilitate the work of biodiversity researchers and managers. LifeWatchGreece is one of these nodes where a portal was developed offering access to a suite of virtual laboratories and e-services.
Despite its strict definition in information technology, in practice "portal" is a fairly broad term that embraces many web architectures. In the biodiversity domain, the term "portal" is usually used to indicate either a web site that provides access to a single or an aggregation of data repositories (like: http://indiabiodiversity.org/, http://www.mountainbiodiversity.org/, http://data.freshwaterbiodiversity.eu), a web site that gathers information about various online biodiversity tools (like http://test-eubon.ebd.csic.es/, http://marine.lifewatch.eu/) or a web site that just gathers information and news about the biodiversity domain (like http://chm.moew.government.bg). LifeWatchGreece's portal takes the concept of a portal a step further. In strict IT terms, LifeWatchGreece's portal is partly a portal, partly a platform and partly an aggregator. It includes a number of biodiversity-related web tools integrated into a centrally-controlled software ecosystem. This ecosystem includes subsystems for access control, traffic monitoring, user notifications and web tool management. These subsystems are shared to all the web tools that have been integrated to the portal and thereby are part of this ecosystem. These web tools do not consist in external and completely independent web applications as it happens in most other portals. A quite obvious (to the user) indication of this is the Single-Sign-On (SSO) functionality for all tools and the common user interface wrapper that most of these tools use. Another example of a less obvious functionality is the common user profile that is shared and can be utilized by all tools (e.g user's timezone).
Indifférenciation sexuelle conjugale et confusion des rôles parentaux chez des sujets toxicomanes sous substitution
Authors: Guéguen Charlène , Golse Bernard , Missonnier Sylvain 
Published: October 2016

Dans la rare littérature dédiée à la dynamique conjugale des sujets toxicomanes, plusieurs particularités sont mises en avant : l’indifférenciation sexuelle, la structure conjugale en triade, mais aussi l’investissement du toxique comme « mythe fondateur » du couple. L’article tend à mettre en évidence, chez des couples sous traitement de substitution, de quelle façon l’accès à la parentalité peut être source de bouleversements intenses, notamment par la réintroduction brutale de la différenciation sexuelle. À partir d’entretiens conjugaux, il a été relevé un vécu corporellement et psychiquement effractant au moment de la naissance du premier enfant. On observe une réorganisation de la dynamique conjugale avec une impossibilité à poursuivre la vie conjugale sur le plan sexuel et une confusion des rôles parentaux.
Sexualité récréative des hommes handicapés moteurs
Authors: Mouget Anne-Cécile 
Published: October 2016

À quoi ressemble la sexualité des hommes handicapés moteurs ? Comment gèrent-ils les contraintes imposées par leur corps handicapé ? C’est à travers un ensemble de données (entretiens et données documentaires) que l’article décrit ce qu’ils en disent eux-mêmes. Analyser cette sexualité à partir du concept de « scripts sexuels » permet de comprendre comment l’impossibilité de coller aux normes leur permet de s’en détacher pour construire un répertoire personnel de scripts adaptés à leurs possibilités corporelles et à celles de leurs partenaires. Leur sexualité récréative emprunte à des répertoires variés, dont ceux d’autres groupes minorisés. Elle est marquée par la négociation entre les partenaires de la symbolique des parties du corps ou des pratiques, la souplesse des rôles masculins et féminins, la réciprocité. L’objectif du rapport est souvent la « connexion » entre les partenaires dans un plaisir qui se nourrit du plaisir de l’autre. Non prise en compte dans les recherches habituelles, la sexualité récréative des hommes handicapés moteurs ébranle les normes et montre un potentiel subversif.
