Authors: Wei Wei , Nong Jinpeng , Zhang Guiwen , Tang Linlong , Jiang Xiao , Chen Na , Luo Suqin , Lan Guilian , Zhu Yong
Published: December 2016

A graphene-based long-period fiber grating (LPFG) surface plasmon resonance (SPR) sensor is proposed. A monolayer of graphene is coated onto the Ag film surface of the LPFG SPR sensor, which increases the intensity of the evanescent field on the surface of the fiber and thereby enhances the interaction between the SPR wave and molecules. Such features significantly improve the sensitivity of the sensor. The experimental results demonstrate that the sensitivity of the graphene-based LPFG SPR sensor can reach 0.344 nm%−1 for methane, which is improved 2.96 and 1.31 times with respect to the traditional LPFG sensor and Ag-coated LPFG SPR sensor, respectively. Meanwhile, the graphene-based LPFG SPR sensor exhibits excellent response characteristics and repeatability. Such a SPR sensing scheme offers a promising platform to achieve high sensitivity for gas-sensing applications.
Measurement and Geometric Modelling of Human Spine Posture for Medical Rehabilitation Purposes Using a Wearable Monitoring System Based on Inertial Sensors
Authors: Voinea Gheorghe-Daniel , Butnariu Silviu , Mogan Gheorghe
Published: December 2016

This paper presents a mathematical model that can be used to virtually reconstruct the posture of the human spine. By using orientation angles from a wearable monitoring system based on inertial sensors, the model calculates and represents the curvature of the spine. Several hypotheses are taken into consideration to increase the model precision. An estimation of the postures that can be calculated is also presented. A non-invasive solution to identify the human back shape can help reducing the time needed for medical rehabilitation sessions. Moreover, it prevents future problems caused by poor posture.

Published: December 2016

This study examined the performance of a flexible polymer/multi-walled carbon nanotube (MWCNT) composite sensor array as a function of operating temperature. The response magnitudes of a cost-effective flexible gas sensor array equipped with a heater were measured with respect to five different operating temperatures (room temperature, 40 °C, 50 °C, 60 °C, and 70 °C) via impedance spectrum measurement and sensing response experiments. The selected polymers that were droplet cast to coat a MWCNT conductive layer to form two-layer polymer/MWCNT composite sensing films included ethyl cellulose (EC), polyethylene oxide (PEO), and polyvinylpyrrolidone (PVP). Electrical characterization of impedance, sensing response magnitude, and scanning electron microscope (SEM) morphology of each type of polymer/MWCNT composite film was performed at different operating temperatures. With respect to ethanol, the response magnitude of the sensor decreased with increasing operating temperatures. The results indicated that the higher operating temperature could reduce the response and influence the sensitivity of the polymer/MWCNT gas sensor array. The morphology of polymer/MWCNT composite films revealed that there were changes in the porous film after volatile organic compound (VOC) testing.

Published: December 2016

This paper proposes a view-invariant gait recognition framework that employs a unique view invariant model that profits from the dimensionality reduction provided by Direct Linear Discriminant Analysis (DLDA). The framework, which employs gait energy images (GEIs), creates a single joint model that accurately classifies GEIs captured at different angles. Moreover, the proposed framework also helps to reduce the under-sampling problem (USP) that usually appears when the number of training samples is much smaller than the dimension of the feature space. Evaluation experiments compare the proposed framework’s computational complexity and recognition accuracy against those of other view-invariant methods. Results show improvements in both computational complexity and recognition accuracy.

Published: December 2016

An increasing number of countries are requiring an extended learner permit prior to independent driving. The question of when drivers begin the learner permit period, and how long they hold the permit before advancing to independent licensure has received little research attention. Licensure timing is likely to be related to “push” and “pull” factors which may encourage or inhibit the process. To examine this question, we recruited a sample of 90 novice drivers (49 females and 41 males, average age of 15.6 years) soon after they obtained a learner permit and instrumented their vehicles to collect a range of driving data. Participants completed a series of surveys at recruitment related to factors that may influence licensure timing. Two distinct findings emerged from the time-to-event analysis that tested these push and pull factors in relation to licensure timing. The first can be conceptualized as teens’ motivation to drive (push), reflected in a younger age when obtaining a learner permit and extensive pre-permit driving experience. The second finding was teens’ perceptions of their parents’ knowledge of their activities (pull); a proxy for a parents’ attentiveness to their teens’ lives. Teens who reported higher levels of their parents’ knowledge of their activities took longer to advance to independent driving. These findings suggest time-to-licensure may be related to teens’ internal motivation to drive, and the ability of parents to facilitate or impede early licensure.
Why Take Young Children Outside? A Critical Consideration of the Professed Aims for Outdoor Learning in the Early Years by Teachers from England and Wales
Authors: Bilton Helen , Waters Jane
Published: December 2016

This comparative study between Wales and England was undertaken to better understand what influences or drives the professed aims for outdoor provision of early years teachers; specifically the extent to which professed aims reflect the research-based literature common to both countries, and/or statutory curricular, which differs in each country. The research gathered quantitative and qualitative data through an online survey. Participants were teachers of children aged four to five years working in the respective country’s University partnership schools. Partnership schools are those who work with the University to train teachers. The findings suggest Welsh teachers aim and plan to use their outdoor spaces explicitly for curriculum-related learning more so than their English counterparts who appear not to identify such specific curriculum-related learning outcomes but to emphasise personal/social/dispositional aspects of development for young children when outside. This research indicates how the divergence of education-related policy and curriculum appears to have impacted upon the way practitioners express their aims for outdoor learning in England and Wales. The values underpinning the relative curricular documentation appear to emerge in the intended practice of early years teachers in both countries. The values underpinning the academic discourse related to provision for outdoor activity is much less prominent in the responses to the surveys from English and Welsh teachers.
A Review of Heavy Metal Concentration and Potential Health Implications of Beverages Consumed in Nigeria
Authors: Izah Sylvester , Inyang Iniobong , Angaye Tariwari , Okowa Ifeoma
Published: December 2016

Beverages are consumed in Nigeria irrespective of age, sex, and socioeconomic status. Beverages may be alcoholic (wine, spirits, and beers) or non-alcoholic (soft drink, energy drinks, candies, chocolates, milks). Notwithstanding, most beverages are packed in cans, bottles, and plastics. This paper reviews the concentration of heavy metals from some commercially-packaged beverages consumed in Nigeria. The study found that heavy metal concentrations, including iron, mercury, tin, antimony, cadmium, zinc, copper, chromium, lead, and manganese, seldom exceed the maximum contaminant level recommended by the Standard Organization of Nigeria (SON) and the World Health Organization (WHO) as applicable to drinking water resources. The occurrence of heavy metals in the beverages could have resulted from the feedstocks and water used in their production. Consumption of beverages high in heavy metal could be toxic and cause adverse effect to human health, depending on the rate of exposure and accumulation dosage. This study concludes by suggesting that heavy metal concentration in the feedstocks and water should be monitored by producers, and its concentration in beverages should also be monitored by appropriate regulatory agencies.

Bacillus subtilis ANSB060 isolated from fish gut is very effective in detoxifying aflatoxins in feed and feed ingredients. The purpose of this research was to investigate the effects of B. subtilis ANSB060 on growth performance, body antioxidant functions, and aflatoxin residues in ducks fed moldy maize naturally contaminated with aflatoxins. A total of 1500 18-d-old male Cherry Valley ducks with similar body weight were randomly assigned to five treatments with six replicates of 50 ducks per repeat. The experiment design consisted of five dietary treatments labeled as C0 (basal diet containing 60% normal maize), M0 (basal diet containing 60% moldy maize contaminated with aflatoxins substituted for normal maize), M500, M1000, and M2000 (M0 +500, 1000 or 2000 g/t aflatoxin biodegradation preparation mainly consisted of B. subtilis ANSB060). The results showed that ducks fed 22.44 ± 2.46 μg/kg of AFB1 (M0) exhibited a decreasing tendency in average daily gain (ADG) and total superoxide dismutase (T-SOD) activity in serum, and T-SOD and glutathione peroxidase (GSH-Px) activities in the liver significantly decreased along with the appearance of AFB1 and AFM1 compared with those in Group C0. The supplementation of B. subtilis ANSB060 into aflatoxin-contaminated diets increased the ADG of ducks (p > 0.05), significantly improved antioxidant enzyme activities, and reduced aflatoxin accumulation in duck liver. In conclusion, Bacillus subtilis ANSB060 in diets showed an ameliorating effect to duck aflatoxicosis and may be a promising feed additive.

Published: December 2016

At present, Para rubber is an economical crop which provides a high priced product and is in demand by global markets. Consequently, the government of Thailand is promoting the expansion of Para rubber plantations throughout the country. Traditionally, Para rubber was planted and grown only in the southern areas of the country. However, due to the Government’s support and promotion as well as economic reasons, the expansion of Para rubber plantations in the northeast has increased rapidly. This support has occurred without accounting for suitable cultivation of Para rubber conditions, particularly in areas with steep slopes and other factors which have significant impacts on hydrology and water quality. This study presents the impacts of Para rubber expansion by applying the Soil and Water Assessment Tool (SWAT) hydrological model on the hydrology and water balance of the Nam Loei River Basin, Loei Province. The results showed that the displacement of original local field crops and disturbed forest land by Para rubber production resulted in an overall increase of evapotranspiration (ET) of roughly 3%. The major factors are the rubber canopy and precipitation. Moreover, the water balance results showed an annual reduction of about 3% in the basin average water yield, especially during the dry season.
Impact of Water Management on Rice Varieties, Yield, and Water Productivity under the System of Rice Intensification in Southern Taiwan
Authors: Pascual Victoriano , Wang Yu-Min
Published: December 2016

The system of rice intensification (SRI) uses less water and enhances rice yield through synergy among several agronomic management practices. This claim was investigated to determine the effects of crop growth, yield and irrigation water use, using two thirds of the recommended SRI practices and two rice varieties, namely Tainan11 (TN11) and Tidung30 (TD30). Irrigation regimes were (a) intermittent irrigation with three-day intervals (TD303 and TN113); (b) intermittent irrigation with seven-day intervals (TD307 and TN117) and (c) continuous flooding (TD30F and TN11F). Results showed that intermittent irrigation of three- and seven-day intervals produced water savings of 55% and 74% compared with continuous flooding. Total water productivity was greater with intermittent irrigation at seven-day intervals producing 0.35 kg·grain/m3 (TN117) and 0.46 kg·grain/m3 (TD307). Average daily headed panicle reduced by 166% and 196% for TN113 and TN117 compared with TN11F, with similar reduction recorded for TD303 (150%) and TD307 (156%) compared with TD30F. Grain yield of TD30 was comparable among irrigation regimes; however, it reduced by 30.29% in TN117 compared to TN11F. Plant height and leaf area were greater in plants exposed to intermittent irrigation of three-day intervals.

Published: December 2016

In recent years, risk stratification has sparked interest as an innovative approach to disease screening and prevention. The approach effectively personalizes individual risk, opening the way to screening and prevention interventions that are adapted to subpopulations. The international PERSPECTIVE project, which is developing risk stratification for breast cancer, aims to support the integration of its screening approach into clinical practice through comprehensive tool-building. Policies and guidelines for risk stratification—unlike those for population screening programs, which are currently well regulated—are still under development. Indeed, the development of guidelines for risk stratification reflects the translational aspects of PERSPECTIVE. Here, we describe the risk stratification process that was devised in the context of PERSPECTIVE, and we then explain the consensus-based method used to develop recommendations for breast cancer screening and prevention in a risk-stratification approach. Lastly, we discuss how the recommendations might affect current screening policies.

Published: December 2016

Purpose: In current fiscally constrained health care systems, the transition of cancer survivors to primary care from tertiary care settings is becoming more common and necessary. The purpose of our study was to explore the experiences of survivors who are transitioning from tertiary to primary care. Methods: One focus group and ten individual telephone interviews were conducted. Data saturation was reached with 13 participants. All sessions were audio-recorded, transcribed verbatim, and analyzed using a qualitative descriptive approach. Results: Eight categories relating to the main content category of transition readiness were identified in the analysis. Several factors affected participant transition readiness: how the transition was introduced, perceived continuity of care, support from health care providers, clarity of the timeline throughout the transition, and desire for a “roadmap.” Although all participants spoke about the effect of their relationships with health care providers (tertiary, transition, and primary care), their relationship with the primary care provider had the most influence on their transition readiness. Conclusions: Our study provided insights into survivor experiences during the transition to primary care. Transition readiness of survivors is affected by many factors, with their relationship with the primary care provider being particularly influential. Understanding transition readiness from the survivor perspective could prove useful in ensuring patient-centred care as transitions from tertiary to primary care become commonplace.
Sensor-Controlled Scalp Cooling to Prevent Chemotherapy-Induced Alopecia in Female Cancer Patients

Published: December 2016

Background: Scalp cooling has been used since the 1970s to prevent chemotherapy-induced alopecia, one of the most common and psychologically troubling side effects of chemotherapy. Currently available scalp cOf the 55 patients, 78% underwent scalp cooling untilooling systems demonstrate varying results in terms of effectiveness and tolerability. Methods: For the present prospective study, 55 women receiving neoadjuvant, adjuvant, or palliative chemotherapy were enrolled. The aim was to assess the effectiveness of a sensor-controlled scalp cooling system (DigniCap: Sysmex Europe GmbH, Norderstedt, Germany) to prevent chemotherapy-induced alopecia in breast or gynecologic cancer patients receiving 1 of 7 regimens. Clinical assessments, satisfaction questionnaires, and alopecia evaluations [World Health Organization (WHO) grading for toxicity] were completed at baseline, at each cycle, and at completion of chemotherapy. Results: Of the 55 patients, 78% underwent scalp cooling until completion of chemotherapy. In multivariate analysis, younger women and those receiving paclitaxel weekly or paclitaxel–carboplatin experienced less alopecia. The compound successful outcome (“no head covering” plus “WHO grade 0/1”) was observed in all patients 50 years of age and younger receiving 4 cycles of docetaxel–cyclophosphamide or 6 cycles of paclitaxel–carboplatin. Conversely, alopecia was experienced by all women receiving triplet polychemotherapy (6 cycles of docetaxel–doxorubicin–cyclophosphamide). For women receiving sequential polychemotherapy regimens (3 cycles of fluorouracil–epirubicin–cyclophosphamide followed by 3 cycles of docetaxel or 4 cycles of doxorubicin–cyclophosphamide followed by 4 cycles of docetaxel), the subgroup 50 years of age and younger experienced a 43% success rate compared with a 10% rate for the subgroup pf older women receiving the same regimens. Conclusions: The ability of scalp cooling to prevent chemotherapy-induced alopecia varies with the chemotherapy regimen and the age of the patient. Use of a compound endpoint with subjective and objective measures provides insightful and practical information when counselling patients.
Adjuvant Systemic Chemotherapy for Stages II and III Colon Cancer after Complete Resection: A Clinical Practice Guideline
Authors: Meyers B.M. , Cosby R. , Quereshy F. , Jonker D.
Published: December 2016

Background Updated practice guidelines on adjuvant chemotherapy for completely resected colon cancer are lacking. In 2008, Cancer Care Ontario’s Program in Evidence-Based Care developed a guideline on adjuvant therapy for stages ii and iii colon cancer. With newer regimens being assessed in this patient population and older agents being either abandoned because of non-effectiveness or replaced by agents that are more efficacious, a full update of the original guideline was undertaken. Methods Literature searches (January 1987 to August 2015) of MEDLINE, EMBASE, and the Cochrane Library were conducted; in addition, abstracts from the American Society of Clinical Oncology, the European Society for Medical Oncology, and the European Cancer Congress were reviewed (the latter for January 2007 to August 2015). A practice guideline was drafted that was then scrutinized by internal and external reviewers whose comments were incorporated into the final guideline. Results Twenty-six unique reports of eighteen randomized controlled trials and thirteen unique reports of twelve meta-analyses or pooled analyses were included in the evidence base. The 5 recommendations developed included 3 for stage ii colon cancer and 2 for stage iii colon cancer. Conclusions Patients with completely resected stage iii colon cancer should be offered adjuvant 5-fluorouracil (5FU)–based chemotherapy with or without oxaliplatin (based on definitive data for improvements in survival and disease-free survival). Patients with resected stage ii colon cancer without “high-risk” features should not receive adjuvant chemotherapy. For patients with “high-risk” features, 5FU-based chemotherapy with or without oxaliplatin should be offered, although no clinical trials have been conducted to conclusively demonstrate the same benefits seen in stage iii colon cancer.
Annual Surveillance Mammography After Early-Stage Breast Cancer and Breast Cancer Mortality
Authors: Paszat L.F. , Sutradhar R. , Gu S. , Rakovitch E.
Published: December 2016

Background: After treatment for early-stage breast cancer (bca), annual surveillance mammography (asm) is recommended based on the assumption that early detection of an invasive ipsilateral breast tumour recurrence or subsequent invasive contralateral primary bca reduces bca mortality. Methods: We studied women with unilateral early-stage bca treated by breast-conserving surgery from 1994 to 1997 who subsequently developed an ipsilateral recurrence or contralateral primary more than 24 months after initial diagnosis, without prior regional or distant metastases. Annual surveillance mammography was defined as 2 episodes of bilateral mammography 11–18 months apart during the 2 years preceding the ipsilateral recurrence or contralateral primary. The association between asm and bca death was evaluated using a Cox proportional hazards model. Results: We identified 669 women who experienced invasive ipsilateral recurrence (n = 455) or a contralateral primary (n = 214) at a median interval of 53 months [interquartile range (iqr): 37–72 months] after initial diagnosis, 64.7% of whom had received asm during the preceding 2 years. The median interval between the 2 bilateral mammograms was 12.3 months (iqr: 11.9–13.0 months), and the median interval between the 2nd mammogram and histopathologic confirmation of ipsilateral recurrence or contralateral primary was 1.5 months (iqr: 0.8–3.9 months). Median followup after ipsilateral recurrence or contralateral primary was 7.76 years (iqr: 3.68–9.81 years). The adjusted hazard ratio for bca death associated with asm was 0.86 (95% confidence limits: 0.63, 1.16). Conclusions: Annual surveillance mammography was associated with a modestly lowered hazard ratio for bca death.

Published: December 2016

With no treatment standard having been established for relapsed and refractory follicular lymphoma, a number of therapeutic approaches are used in Canada. In patients who relapse early or who eventually become resistant to subsequent treatment, prognosis is poor, and new approaches are needed. A number of novel therapies are being examined in this setting, including monoclonal antibodies, immunoconjugates, immunomodulatory agents, and signal transduction inhibitors. With the body of evidence for those emerging therapies accumulating and the standard upfront treatment changing from rituximab and chop (cyclophosphamide–doxorubicin–vincristine–prednisone) or rituximab and cvp (cyclophosphamide–vincristine–prednisone) to bendamustine and rituximab, treatment decisions in the relapsed and refractory setting have become more complex. The choice of subsequent treatment must consider type of upfront treatment; duration of remission; and patient-related factors such as age, comorbidities, and treatment preferences. This paper summarizes the evidence for novel therapies and proposes recommendations for subsequent treatment options by remission duration after induction and maintenance.

A series of SnO2–ZnO composite nanostructured (thin) films with different amounts of SnO2 (from 0 to 50 wt %) was prepared and deposited on a miniaturized porous alumina transducer using the sol–gel and dip coating method. The transducer, developed by our research group, contains Au interdigital electrodes on one side and a Pt heater on the other side. The sensing films were characterized using SEM and AFM techniques. Highly toxic and flammable gases (CO, CO2, CH4, and C3H8) were tested under lab conditions (carrier gas was dry air) using a special gas sensing cell developed by our research group. The gas concentrations varied between 5 and 2000 ppm and the optimum working temperatures were in the range of 210–300 °C. It was found that the sensing performance was influenced by the amount of oxide components present in the composite material. Improved sensing performance was achieved for the ZnO (98 wt %)–SnO2 (2 wt %) composite as compared to the sensors containing only the pristine oxides. The sensor response, cross-response and recovery characteristics of the analyzed materials are reported. The high sensitivity (RS = 1.21) to low amounts of CO (5 ppm) was reported for the sensor containing a composite sensitive film with ZnO (98 wt %)–SnO2 (2 wt %). This sensor response to CO was five times higher as compared to its response to CO2, CH4, and C3H8, thus the sensor is considered to be selective for CO under these test conditions.

828 mas yr−1 and 3.85

8.47. Among these are 58 systems from the SuperCOSMOS-RECONS search, discovered via our proper motion trawls of the SuperCOSMOS digitized archival photographic plates, while the remaining stars were suspected via photometric distance estimates to lie nearby. Sixteen systems were newly discovered via astrometric perturbations to be binaries, many of which are ideal for accurate mass determinations due to their proximity and orbital periods on the order of a decade. A variability analysis of the stars presented, two-thirds of which are new results, shows six of the stars to vary by more than 20 mmag. This effort brings the total number of parallaxes for M dwarf systems measured by RECONS to nearly 500 and increases by 26% the number of southern M dwarf systems with accurate trigonometric parallaxes placing them within 25 pc.
RESURRECTION OF (3200) PHAETHON IN 2016
Authors: Hui(許文韜) Man-To , Li(李京) Jing
Published: December 2016

We present a study of the active asteroid (3200) Phaethon in the 2016 apparition using the Solar and Terrestrial Relations Observatory (STEREO) spacecraft and compare the results with data from the previous two perihelia in 2009 and 2012. Once again, Phaethon brightened by ∼2 mag soon after its perihelion passage, contradicting expectations from the phase function of a macroscopic monolithic body. Subsequently, a short antisolar tail of ∼0.°1 in length was formed within ∼1 day and quickly disappeared. No trail was seen. Our syndyne-synchrone analysis indicates that the tail was comprised of submicron to micron particles and can be approximated by a synchrone coinciding with the outburst. We estimate that the outburst has released a mass of ∼104–105 kg, comparable to the two mass ejections in 2009 and 2012, and that the average mass-loss rate is ∼0.1–1 kg s−1. The forward-scattering effect hinted at low level activity of Phaethon prior to the outburst, which increased the effective cross section by merely ≲1 km2. Without the forward-scattering enhancement, detecting such activity at side-scattering phase angles is very difficult. The forward-scattering effect also reinforces the idea that the ejected dust grains rather than gas emissions were responsible for the activity of Phaethon. Despite Phaethon's reactivation, it is highly unlikely that the Geminid meteoroid stream can be sustained by similar perihelion mass-loss events.

We determine probabilities of physical association for stars in blended Kepler Objects of Interest (KOIs), and find that

This produces a better understanding of potential false positives in the Kepler catalog and will guide models of planet formation in binary systems. Physical association is determined through two methods of calculating multi-band photometric parallax using visible and near-infrared adaptive optics observations of 84 KOI systems with 104 contaminating companions within ∼4″. We find no evidence that KOI companions with separations of less than 1″ are more likely to be physically associated than KOI companions generally. We also reinterpret transit depths for 94 planet candidates, and calculate that 2.6% ± 0.4% of transits have

THE INCLINATION OF THE PLANETARY SYSTEM RELATIVE TO THE SOLAR EQUATOR MAY BE EXPLAINED BY THE PRESENCE OF PLANET 9
Authors: Gomes Rodney , Deienno Rogerio , Morbidelli Alessandro
Published: December 2016

We evaluate the effects of a distant planet, commonly known as planet 9, on the dynamics of the giant planets of the solar system. We find that the dynamics of the giant planets can be decomposed into a classic Lagrange–Laplace dynamics relative to their own invariant plane and a slow precession of said plane relative to the total angular momentum vector of the solar system, including planet 9. Under specific configurations for planet 9, this precession can explain the current tilt of ∼6° between the invariant plane of the giant planets and the solar equator. An analytical model is developed to map the evolution of the inclination of the inner giant planets’ invariant plane as a function of the planet 9's mass and orbital elements, and numerical simulations of the equations of motion are performed to validate our analytical approach. The longitude of the ascending node of planet 9 is found to be linked to the longitude of the ascending node of the giant planets’ invariant plane, which also constrains the longitude of the node of planet 9 on the ecliptic. Some of the planet 9 configurations that allow the explanation of the current solar tilt are compatible with those proposed to explain the orbital confinement of distant Kuiper Belt objects. This work gives an elegant explanation for the current tilt between the invariant plane of the inner giant planets and the solar equator and also adds new constraints to the orbital elements of planet 9.
HIGH RESOLUTION He i 10830 Å NARROW-BAND IMAGING OF AN M-CLASS FLARE. I. ANALYSIS OF SUNSPOT DYNAMICS DURING FLARING

Published: December 2016

In this paper, we report our first-step results of high resolution He i 10830 Å narrow-band imaging (bandpass: 0.5 Å) of an M1.8 class two-ribbon flare on 2012 July 5. The flare was observed with the 1.6 m aperture New Solar Telescope at Big Bear Solar Observatory. For this unique data set, sunspot dynamics during flaring were analyzed for the first time. By directly imaging the upper chromosphere, running penumbral waves are clearly seen as an outward extension of umbral flashes; both take the form of absorption in the 10830 Å narrow-band images. From a space–time image made of a slit cutting across a flare ribbon and the sunspot, we find that the dark lanes for umbral flashes and penumbral waves are obviously broadened after the flare. The most prominent feature is the sudden appearance of an oscillating absorption strip inside the ribbon when it sweeps into the sunspot’s penumbral and umbral regions. During each oscillation, outwardly propagating umbral flashes and subsequent penumbral waves rush out into the inwardly sweeping ribbon, followed by a return of the absorption strip with similar speed. We tentatively explain the phenomena as the result of a sudden increase in the density of ortho-helium atoms in the area of the sunspot being excited by the flare’s extreme ultraviolet illumination. This explanation is based on the observation that 10830 Å absorption around the sunspot area gets enhanced during the flare. Nevertheless, questions are still open and we need further well-devised observations to investigate the behavior of sunspot dynamics during flares.
DOES A DIFFERENTIATED, CARBONATE-RICH, ROCKY OBJECT POLLUTE THE WHITE DWARF SDSS J104341.53+085558.2?

We present spectroscopic observations of the dust- and gas-enshrouded, polluted, single white dwarf star SDSS J104341.53+085558.2 (hereafter SDSS J1043+0855). Hubble Space Telescope Cosmic Origins Spectrograph far-ultraviolet spectra combined with deep Keck HIRES optical spectroscopy reveal the elements C, O, Mg, Al, Si, P, S, Ca, Fe, and Ni and enable useful limits for Sc, Ti, V, Cr, and Mn in the photosphere of SDSS J1043+0855. From this suite of elements we determine that the parent body being accreted by SDSS J1043+0855 is similar to the silicate Moon or the outer layers of Earth in that it is rocky and iron-poor. Combining this with comparison to other heavily polluted white dwarf stars, we are able to identify the material being accreted by SDSS J1043+0855 as likely to have come from the outermost layers of a differentiated object. Furthermore, we present evidence that some polluted white dwarfs (including SDSS J1043+0855) allow us to examine the structure of differentiated extrasolar rocky bodies. Enhanced levels of carbon in the body polluting SDSS J1043+0855 relative to the Earth–Moon system can be explained with a model where a significant amount of the accreted rocky minerals took the form of carbonates; specifically, through this model the accreted material could be up to 9% calcium-carbonate by mass.
EQUATION OF STATE FOR NUCLEONIC AND HYPERONIC NEUTRON STARS WITH MASS AND RADIUS CONSTRAINTS
Authors: Tolos Laura , Centelles Mario , Ramos Angels
Published: December 2016

We obtain a new equation of state for the nucleonic and hyperonic inner core of neutron stars that fulfils the 2 M
⊙ observations as well as the recent determinations of stellar radii below 13 km. The nucleonic equation of state is obtained from a new parameterization of the FSU2 relativistic mean-field functional that satisfies these latest astrophysical constraints and, at the same time, reproduces the properties of nuclear matter and finite nuclei while fulfilling the restrictions on high-density matter deduced from heavy-ion collisions. On the one hand, the equation of state of neutron star matter is softened around saturation density, which increases the compactness of canonical neutron stars leading to stellar radii below 13 km. On the other hand, the equation of state is stiff enough at higher densities to fulfil the 2 M
⊙ limit. By a slight modification of the parameterization, we also find that the constraints of 2 M
⊙ neutron stars with radii around 13 km are satisfied when hyperons are considered. The inclusion of the high magnetic fields present in magnetars further stiffens the equation of state. Hyperonic magnetars with magnetic fields in the surface of ∼1015 G and with values of ∼1018 G in the interior can reach maximum masses of 2 M
⊙ with radii in the 12–13 km range.
X-RAY/GeV EMISSIONS FROM CRAB-LIKE PULSARS IN THE LMC
Authors: Takata J. , Cheng K. S.
Published: December 2016

We discuss X-ray and gamma-ray emissions from Crab-like pulsars, PSRs J0537-6910 and J0540-6919, in the Large Magellanic Cloud. Fermi-LAT observations have resolved the gamma-ray emissions from these two pulsars and found pulsed emissions from PSR J0540-6919. The total pulsed radiation in the X-ray/gamma-ray energy bands of PSR J0540-6919 is observed with efficiency

(in 4π sr), which is about a factor of ten larger than

of the Crab pulsar. Although PSR J0537-6910 has the highest spin-down power among currently known pulsars, the efficiency of the observed X-ray emissions is about two orders of magnitude smaller than that of PSR J0540-6919. This paper mainly discusses what causes the difference in the radiation efficiencies of these three energetic Crab-like pulsars. We discuss electron/positron acceleration and high-energy emission processes within the outer gap model. By solving the outer gap structure with the dipole magnetic field, we show that the radiation efficiency decreases as the inclination angle between the magnetic axis and the rotation axis increases. To explain the difference in the pulse profile and in the radiation efficiency, our model suggests that PSR J0540-6919 has an inclination angle much smaller than that of the Crab pulsar (here we assume the inclination angles of both pulsars are

). On the other hand, we speculate that the difference in the radiation efficiencies between PSRs J0537-6910 and J0549-6919 is mainly caused by the difference in the Earth viewing angle, and that we see PSR J0537-6910 with an Earth viewing angle

(or

) measured from the spin axis, while we see PSR J0540-6919 with

We present Keck/DEIMOS spectroscopy of individual stars in the relatively isolated Local Group dwarf galaxies Leo A, Aquarius, and the Sagittarius dwarf irregular galaxy. The three galaxies—but especially Leo A and Aquarius—share in common delayed star formation histories (SFHs) relative to many other isolated dwarf galaxies. The stars in all three galaxies are supported by dispersion. We found no evidence of stellar velocity structure, even for Aquarius, which has rotating H i gas. The velocity dispersions indicate that all three galaxies are dark-matter-dominated, with dark-to-baryonic mass ratios ranging from

(SagDIG) to

(Aquarius). Leo A and SagDIG have lower stellar metallicities than Aquarius, and they also have higher gas fractions, both of which would be expected if Aquarius were further along in its chemical evolution. The metallicity distribution of Leo A is inconsistent with a closed or leaky box model of chemical evolution, suggesting that the galaxy was pre-enriched or acquired external gas during star formation. The metallicities of stars increased steadily for all three galaxies, but possibly at different rates. The [α/Fe] ratios at a given [Fe/H] are lower than that of the Sculptor dwarf spheroidal galaxy, which indicates more extended SFHs than Sculptor, consistent with photometrically derived SFHs. Overall, the bulk kinematic and chemical properties for the late-forming dwarf galaxies do not diverge significantly from those of less delayed dwarf galaxies, including dwarf spheroidal galaxies.
Juger, est-ce interpréter ?
Authors: Regis Nicolas
Published: December 2016

Penser l’acte de décider en droit comme une opération mentale d’interprétation conduit bien souvent à en faire un objet métaphysique donné à la connaissance du droit et non construit par elle. Cette réification implique également de recourir à un modèle causal de la décision judiciaire, lequel recèle de nombreuses difficultés au regard du caractère proprement juridique d’une telle enquête. En appréhendant cette problématique de la décision par les outils de la philosophie analytique de l’esprit et de l’action, cet article entend défendre une autre approche qui, dans le prolongement des travaux du juriste Hans Kelsen, s’efforce de penser la décision judiciaire comme un acte de justification au sein d’un cadre de rationalité stipulé.
L'office du juge et la liturgie du juste
Authors: Bernabé Boris
Published: December 2016

En règle générale, l’office du juge est réduit aux possibilités techniques offertes au juge par les codes pour exercer sa fonction. Or, l’office du juge est bien plus que cela. Il est l’expression d’un pouvoir autonome d’une force considérable, distinct du pouvoir qui offre au juge sa légitimité. Qu’est-ce qui fonde alors ce pouvoir propre ? Il apparaît que ce « mystère », ainsi que l’évoquait Pierre Ayrault au XVI e siècle, se niche au cœur de la dimension liturgique de la forme de procéder . Or, cette théorie de l’office du juge prend un sens particulier aujourd’hui, dans un monde où l’autorité des normes se renverse.
Annotated Potron bibliography
Authors: Parys Wilfried
Published: December 2016

Maurice Potron (1872-1942) est un précurseur important de l’analyse Input-Output. Il n’a jamais publié dans des revues prestigieuses en économie et beaucoup de ses écrits sont difficiles à trouver. Pour toutes ces raisons, il est utile de fournir une bibliographie de ses écrits scientifiques, qu’ils aient été ou non publiés. Cette bibliographie intègre de nombreuses notes sur les écrits de Potron et les très rares références à ces écrits parues avant 2000 (année pendant laquelle un remarquable article de Lendjel a enfin attiré l’attention sur la pensée économique de Potron).
Equilibrium and economic policy in W. Leontief’s theory
Authors: Reyes Fidel Aroche
Published: December 2016

Leontief a peu écrit sur la politique économique, car il était fondamentalement un économiste appliqué, préoccupé de développer la théorie permettant d’expliquer des phénomènes réels. Ses contributions les plus importantes sont associées à des modèles d’équilibre qui rendent la politique publique inutile. Cependant, cet article explore quelques écrits de Leontief en rapport avec trois exemples concernant la politique économique, à savoir le programme d’aide du gouvernement des Etats-Unis destiné à lutter contre les effets de la récession des années 1930, la théorie de la demande effective de Keynes et l’étude des impacts économiques du désarmement. Tout bien considéré, il apparaît qu’avec l’âge ses opinions sur le rôle de la politique économique sont devenues plus flexibles, bien qu’il n’ait pas modifié ses conclusions antérieures sur l’équilibre économique.
Sortir de nos ornières mentales
Authors: Quentin Bertrand
Published: December 2016

Les contemporains dits valides sont bien souvent pris dans des ornières mentales qu’il nous faut décrire pour pouvoir mieux les dépasser. Repérons donc le va-et-vient entre physique et mental, le va-et-vient entre nécessaire énonciation d’une différence et reconnaissance d’identités, le va-et-vient entre universalisme exigeant et communautarisme protecteur. Enfin, repérons les graves conséquences dans notre rapport aux personnes handicapées de « l’empathie égocentrée » et des « compensations inopportunes ». Le handicap s’avère être un concept relatif et relationnel.
Les instituts médico-éducatifs à l’épreuve d’un environnement toujours plus exigeant
Authors: Pich-Traveset Sandrine
Published: December 2016

L’environnement dans lequel évoluent les ime les invite à une adaptation permanente de leurs modes d’organisation et de fonctionnement et des accompagnements proposés. Les contraintes sont nombreuses et pour répondre aux besoins nouveaux identifiés, les gestionnaires d’ ime doivent s’inscrire dans un cadre législatif et règlementaire rénové auquel est soumis le nouveau régime des autorisations. Les agences régionales de santé ont pour levier les appels à projets pour structurer l’offre médicosociale d’une façon globale, mais aussi les inspections qui donnent lieu à des mesures correctives.
Organiser l’orientation et la gestion des situations critiques en IME
Authors: Galet Jacques
Published: December 2016

Le tout évaluatif et l’empilement législatif n’ont pu éviter le maintien d’un grand nombre d’enfants ou d’adolescents dans des situations critiques. La déclinaison des valeurs qui fondent nos associations ne peut être circonscrite au seul discours tenu sur le handicap, dans une acception politique et concurrentielle. Un projet, qu’il soit individuel, d’établissement ou associatif, ne vaut que par l’effectivité de sa mise en œuvre. Dépasser les clivages sectoriels et associatifs pour passer du discours politique à l’élaboration d’une réponse accompagnée pour tous est une belle promesse qui va devoir engager tous les acteurs.
Mais à quoi ça sert un IME ?
Authors: Capdegelle Evelyne
Published: December 2016

Le secteur médicosocial est soumis à un cadre législatif et règlementaire qui est venu impacter les pratiques. Notre ime n’échappe pas à la règle : expérimental à l’origine, il continue, au sein d’un Pôle enfance mêlant médicosocial et sanitaire, à évoluer dans ses pratiques. Les troubles du public ont aussi évolué vers plus de soins : « C’est drôle, les enfants ont l’air normaux. » Aujourd’hui, une organisation particulière répond aux besoins spécifiques, à travers des passerelles, des parcours, un réseau partenarial solide et des projets pour demain.
