ABSTRACT
Until recently, only a handful of dusty, star-forming galaxies (DSFGs) were known at z > 4, most of them significantly amplified by gravitational lensing. Here, we have increased the number of such DSFGs substantially, selecting galaxies from the uniquely wide 250, 350, and 500 μm Herschel-ATLAS imaging survey on the basis of their extremely red far-infrared colors and faint 350 and 500 μm flux densities, based on which, they are expected to be largely unlensed, luminous, rare, and very distant. The addition of ground-based continuum photometry at longer wavelengths from the James Clerk Maxwell Telescope and the Atacama Pathfinder Experiment allows us to identify the dust peak in their spectral energy distributions (SEDs), with which we can better constrain their redshifts. We select the SED templates that are best able to determine photometric redshifts using a sample of 69 high-redshift, lensed DSFGs, then perform checks to assess the impact of the CMB on our technique, and to quantify the systematic uncertainty associated with our photometric redshifts, σ = 0.14 (1 + z), using a sample of 25 galaxies with spectroscopic redshifts, each consistent with our color selection.

ON THE WHITE DWARF MASS PROBLEM OF CATACLYSMIC VARIABLES
Authors: Liu Wei-Min , Li Xiang-Dong 
Published: November 2016

ABSTRACT
Recent observations show that white dwarfs (WDs) in cataclysmic variables (CVs) have an average mass significantly higher than isolated WDs and WDs in post-common envelope binaries (PCEBs), which are thought to be the progenitors of CVs. This suggests that either the WDs have grown in mass during the PCEB/CV evolution or the binaries with low-mass WDs are unable to evolve to be CVs. In this paper, we calculate the evolution of accreting WD binaries with updated hydrogen accumulation efficiency and angular momentum loss (AML) prescriptions. We show that thermal-timescale mass transfer is not effective in changing the average WD mass distribution. The WD mass discrepancy is most likely related to unstable mass transfer in WD binaries, in which an efficient mechanism of AML is required.
SN2002es-LIKE SUPERNOVAE FROM DIFFERENT VIEWING ANGLES

ABSTRACT
In this article, we compare optical light curves of two SN2002es-like Type Ia supernovae (SNe), iPTF14atg and iPTF14dpk, from the intermediate Palomar Transient Factory. Although the two light curves resemble each other around and after maximum, they show distinct early-phase rise behavior in the r-band. On the one hand, iPTF14atg revealed a slow and steady rise that lasted for 22 days with a mean rise rate of 0.2–0.3 mag day–1, before it reached the R-band peak (−18.05 mag). On the other hand, iPTF14dpk rose rapidly to −17 mag within a day of discovery with a rise rate

, and then rose slowly to its peak (−18.19 mag) with a rise rate similar to iPTF14atg. The apparent total rise time of iPTF14dpk is therefore only 16 days. We show that emission from iPTF14atg before −17 days with respect to its maximum can be entirely attributed to radiation produced by collision between the SN and its companion star. Such emission is absent from iPTF14dpk probably because of an unfavored viewing angle, provided that SN2002es-like events arise from the same progenitor channel. We further show that an SN2002es-like SN may experience a dark phase after the explosion but before its radioactively powered light curve becomes visible. This dark phase may be lit by radiation from supernova–companion interaction.
MEASURING NEUTRON STAR RADII VIA PULSE PROFILE MODELING WITH NICER

Published: November 2016

ABSTRACT
The Neutron-star Interior Composition Explorer is an X-ray astrophysics payload that will be placed on the International Space Station. Its primary science goal is to measure with high accuracy the pulse profiles that arise from the non-uniform thermal surface emission of rotation-powered pulsars. Modeling general relativistic effects on the profiles will lead to measuring the radii of these neutron stars and to constraining their equation of state. Achieving this goal will depend, among other things, on accurate knowledge of the source, sky, and instrument backgrounds. We use here simple analytic estimates to quantify the level at which these backgrounds need to be known in order for the upcoming measurements to provide significant constraints on the properties of neutron stars. We show that, even in the minimal-information scenario, knowledge of the background at a few percent level for a background-to-source countrate ratio of 0.2 allows for a measurement of the neutron star compactness to better than 10% uncertainty for most of the parameter space. These constraints improve further when more realistic assumptions are made about the neutron star emission and spin, and when additional information about the source itself, such as its mass or distance, are incorporated.

ABSTRACT
We present cosmological parameter constraints obtained from galaxy clusters identified by their Sunyaev–Zel’dovich effect signature in the 2500 square-degree South Pole Telescope Sunyaev Zel’dovich (SPT-SZ) survey. We consider the 377 cluster candidates identified at

with a detection significance greater than five, corresponding to the 95% purity threshold for the survey. We compute constraints on cosmological models using the measured cluster abundance as a function of mass and redshift. We include additional constraints from multi-wavelength observations, including Chandra X-ray data for 82 clusters and a weak lensing-based prior on the normalization of the mass-observable scaling relations. Assuming a spatially flat ΛCDM cosmology, we combine the cluster data with a prior on H

ABSTRACT
The central region of the Virgo Cluster of galaxies contains thousands of globular clusters (GCs), an order of magnitude more than the number of clusters found in the Local Group. Relics of early star formation epochs in the universe, these GCs also provide ideal targets to test our understanding of the spectral energy distributions (SEDs) of old stellar populations. Based on photometric data from the Next Generation Virgo Cluster Survey (NGVS) and its near-infrared counterpart NGVS-IR, we select a robust sample of

GCs with excellent photometry and tha span the full range of colors present in the Virgo core. The selection exploits the well-defined locus of GCs in the uiK diagram and the fact that the GCs are marginally resolved in the images. We show that the GCs define a narrow sequence in five-dimensional color space, with limited but real dispersion around the mean sequence. The comparison of these SEDs with the predictions of 11 widely used population synthesis models highlights differences between the models and also shows that no single model adequately matches the data in all colors. We discuss possible causes for some of these discrepancies. Forthcoming papers of this series will examine how best to estimate photometric metallicities in this context, and compare the Virgo GC colors with those in other environments.
ROCKY PLANETESIMAL FORMATION VIA FLUFFY AGGREGATES OF NANOGRAINS
Authors: Arakawa Sota , Nakamoto Taishi 
Published: November 2016

ABSTRACT
Several pieces of evidence suggest that silicate grains in primitive meteorites are not interstellar grains but condensates formed in the early solar system. Moreover, the size distribution of matrix grains in chondrites implies that these condensates might be formed as nanometer-sized grains. Therefore, we propose a novel scenario for rocky planetesimal formation in which nanometer-sized silicate grains are produced by evaporation and recondensation events in early solar nebula, and rocky planetesimals are formed via aggregation of these nanograins. We reveal that silicate nanograins can grow into rocky planetesimals via direct aggregation without catastrophic fragmentation and serious radial drift, and our results provide a suitable condition for protoplanet formation in our solar system.
Hemophilia in Sports: A Case Report and Prophylactic Protocol
Authors: Maffet Mark , Roton Jimmy 
Published: November 2016

Objective: To describe a successful prophylactic protocol for managing an athlete with hemophilia playing at a high level of contact sports.
Background: Published data show that team physicians are not comfortable either treating athletes with bleeding disorders or allowing them to participate in contact sports. Much of the literature historically has recommended against allowing athletes with bleeding disorders to play sports at all and certainly against playing contact sports. Hemophilia treatment can now include prophylactic injections of recombinant factor VIII to prevent bleeding episodes. Modern treatments hold the promise of allowing athletes with hemophilia to participate in contact sports.
Differential Diagnosis: Mild, moderate, or severe hemophilia; von Willebrand disease; other factor deficiencies.
Treatment: A treatment protocol was developed that included prophylactic factor VIII injections on a regular basis and when the athlete was injured.
Uniqueness: This is the first published case report of an athlete with known hemophilia being successfully treated and participating in National Collegiate Athletic Association collegiate basketball for 2 full seasons.
Conclusions: Sports medicine teams can successfully manage an athlete with hemophilia playing a contact sport.
Towards Maturity in 1 Peter: Freedom, Holiness, Immortality
Authors: Decock Paul B. 
Published: November 2016

Growth towards maturity is dependent on the presence of freedom, holiness and immortality. These are presented as divine qualities that are utterly lacking in human beings. However, while human beings are ignorant and weak, sinful and mortal the addressees of 1 Peter1 are reminded that they have also been begotten anew by the imperishable seed of God’s Word, the Good News of Jesus Christ in order to share immortal life. This article looks first at human beings who as God’s creatures are ‘flesh’, but are also enabled to acknowledge their ‘fleshly’ state, to appreciate (‘desire’ and ‘taste’) (2:2–3) the Gospel and to submit to God. The second part considers the saving role of Christ as the powerful yet rejected ‘stone’ placed and offered by God as the model and means to transcend the ‘flesh’ in the flesh (4:1–2). A final part focuses on the new birth and the growth process in which the fleshly desires and ways of living give way to a manner of life, which is a witness to God’s saving power.

After an environmental assessment about gold mine’s operation, a mining company agreed to create a safe area for biodiversity offsets: Dékpa Botanical Reserve. We describe various steps conducted in order to its creation. The objective was to assess the plant diversity of this site, its value for flora conservation, availability of plants for traditional uses in the locality. The study also shows the partnership between scientific, the mining company and local people. Meetings with mining company and local communities of the 5 closest reserve villages, permits to have approval and membership of chiefs’ customary, chiefdoms. They selected 30 young people to serve as community liaisons. These will help in achieving the other development phases of the reserve. Botanical surveys identified 358 species of which 30 are among those classified as rare, threatened or different levels of endemism. These are species such as Cola lorougnonis and Drypetes singroboensis considered as very rare in Ivorian flora. Interviews of local people show that 24% of species can be used in the treatment of various diseases, for food, crafts use or timber. The creation of the Dekpa reserve was the source of improvements for the community and scientific advances. The study suggests that development of reserve activities should consider needs of local people, as their traditional knowledge may be a factor in the preservation of species.
Après une étude d’impact environnemental, une société minière a accepté de créer sur son périmètre d’exploitation, une zone refuge pour la biodiversité : la Réserve Forestière Dékpa. Nous décrivons la première phase de son plan d’aménagement, consacrée à sa diversité végétale, sa valeur pour la conservation de la flore, sa disponibilité en espèces végétales à usages locaux et le rôle joué par les populations locales, la société minière, les chercheurs et la police forestière pour sa création. Des réunions avec les Responsables coutumiers ont permis d’obtenir leur approbation et adhésion. 30 Relais Communautaires ont été proposés et formés pour les autres activités. Le site est riche de 358 espèces dont 30 figurent parmi celles classées rares, menacées ou endémiques. Cola lorougnonis et Drypetes singroboensis sont deux des espèces rares, considérées localement comme en voie de disparition. 24 % peuvent être utilisés dans le traitement de diverses maladies, pour la consommation, l’artisanat ou comme bois d'œuvre. La création de la réserve connait des progrès au plan communautaire et scientifique. L’étude suggère que les activités d'aménagement de la réserve, devront tenir compte des besoins des populations locales car leurs connaissances traditionnelles peuvent être un facteur de conservation de certaines espèces et donc de la forêt.
Performance of site-specific parameterizations of longwave radiation
Authors: Formetta Giuseppe , Bancheri Marialaura , David Olaf , Rigon Riccardo 
Published: November 2016

Abstract. In this work 10 algorithms for estimating downwelling longwave atmospheric radiation (L↓) and 1 for upwelling longwave radiation (L↑) are integrated into the JGrass-NewAge modelling system. The algorithms are tested against energy flux measurements available for 24 sites in North America to assess their reliability. These new JGrass-NewAge model components are used (i) to evaluate the performances of simplified models (SMs) of L↓, as presented in literature formulations, and (ii) to determine by automatic calibration the site-specific parameter sets for L↓ in SMs. For locations where calibration is not possible because of a lack of measured data, we perform a multiple regression using on-site variables, i.e. mean annual air temperature, relative humidity, precipitation, and altitude. The regressions are verified through a leave-one-out cross validation, which also gathers information about the possible errors of estimation. Most of the SMs, when executed with parameters derived from the multiple regressions, give enhanced performances compared to the corresponding literature formulation. A sensitivity analysis is carried out for each SM to understand how small variations of a given parameter influence SM performance. Regarding the L↓ simulations, the Brunt (1932) and Idso (1981) SMs, in their literature formulations, provide the best performances in many of the sites. The site-specific parameter calibration improves SM performances compared to their literature formulations. Specifically, the root mean square error (RMSE) is almost halved and the Kling–Gupta efficiency is improved at all sites. Also in this case, Brunt (1932) and Idso (1981) SMs provided the best performances. The L↑ SM is tested by using three different temperatures (surface soil temperature, air temperature at 2 m elevation, and soil temperature at 4 cm depth) and model performances are then assessed. Results show that the best performances are achieved using the surface soil temperature and the air temperature.
High-efficiency simultaneous three-photon absorption upconversion luminescence of a terbium-doped germanate glass
Authors: Zhang Liaolin , Yang Runlan , Zou Hui , Shen Xiao , Zheng Jiajin , Wei Wei 
Published: November 2016

Abstract
In this paper, high-efficiency green upconversion luminescence from a terbium (Tb3+)-doped germanate glass is reported. The upconversion luminescence involved a simultaneous three-photon absorption process. Compared with an emission spectrum excited at 377 nm, the upconversion luminescence bands of Tb3+ pumped by an fs laser showed a slight red-shift. This was ascribed to the redistribution of glass composition when the glass sample was exposed to the high-intensity laser, which results in the aggregation of Tb3+ around the laser-exposed focal region, which in turn results in the slight red-shift of luminescence. The upconversion luminescence intensities at 540, 590, and 620 nm strongly depended on the polarization angle of the femtosecond laser, which was ascribed to the different transmittances of a half-wavelength plate at different polarization angles, which results in the regularity change in fs laser power.
Correlation between steady-oscillatory flow transition and the interface inversion process during the Czochralski growth of semitransparent oxide crystal
Authors: Faiez Reza , Rezaei Yazdan 
Published: November 2016

Abstract
In this paper, steady-oscillatory transition of the convective flow in a Czochralski (Cz) growth system was numerically studied. In this configuration, rapid variations in density across narrow region of the flow in the vicinity of the crystallization front leads to an unstable stratification of the flow in this region. Time-dependent, finite volume method calculation of the momentum and heat transport equations shows that an instability mechanism, giving rise to the formation of cold plumes beneath the phase boundary, might be associated with an irreversible change in the convexity of the front. Dynamics of the crystallization front was found to be correlated with the periodic oscillation of the flow. It was shown that the interface inversion process occurs at a critical Reynolds number significantly (∼25%) lower than that predicted by the steady-state Cz-oxide model analysis. Consistently, the time-averaged maximum value of stream function was found to be larger than its corresponding steady-state value. This indicates that the mechanism behind the oscillatory transition of the flow has a positive feedback on the intensity of forced convection flow. These numerical results were attributed to the baroclinic instability mechanism characterized by oscillations of a cold plume appearing at the crystal periphery and descending along the symmetry axis. The time period of oscillations was found to be considerably (30–40%) decreases and, simultaneously, the inclination angle of isopycnals increases (∼48%) at a critical rotation rate of the crystal for which the interface inversion occurs.
Global geodynamic changes induced by all major earthquakes, 1976–2015
Authors: Chao Benjamin F. , Ding Hao 
Published: November 2016

AbstractUsing normal‐mode summations we calculate the coseismic changes in a suite of global geodynamic quantities produced by all the 43,304 major earthquakes that occurred during 1976–2015 from the Global Centroid Moment Tensor catalogue. We calculate changes for the Earth's inertia tensor elements and the ensuing Earth's rotation variations, as well as the monopolar changes of the volume ΔV(r), the total moment of inertia ΔT(r), and the gravitational energy ΔEg(r) as functions of the radius inside the Earth. The cumulative geodynamic changes are found to have strong statistical trends that are continuing from the past and further strengthened in recent years. Statistical analyses indicate that the thrust‐faulting earthquakes are predominantly responsible for these trends, as they are the dominant type overshadowing the normal‐faulting earthquakes that tend to produce the opposite effects. In particular, we report that the polar motion excitations due to the few greatest earthquakes since 2004 have facilitated the abrupt turn of the pole path observed during these years. For the monopolar parameters, we find an overall shrinkage in Earth's volume V(r) internally but an expansion near Earth's surface. The ensuing gravitational instability cannot be sustained over time and will be reversed by aseismic and interseismic deformations. The ΔT(r) and ΔEg(r) also exhibit trends where the coseismic action of earthquakes collectively makes the Earth more compact and dissipate a great amount of gravitational energy. Although aseismic effects are not addressed here, these coseismic trends are in keeping with the long‐term physical evolution of the Earth.
