Abstract
A new model describing the transport and evolution of turbulence in the quiet solar corona is presented. In the low plasma beta environment, transverse photospheric convective fluid motions drive predominantly quasi-2D (nonpropagating) turbulence in the mixed-polarity “magnetic carpet,” together with a minority slab (Alfvénic) component. We use a simplified sub-Alfvénic flow velocity profile to solve transport equations describing the evolution and dissipation of turbulence from

(including the Alfvén surface). Typical coronal base parameters are used, although one model uses correlation lengths derived observationally by Abramenko et al., and the other assumes values 10 times larger. The model predicts that (1) the majority quasi-2D turbulence evolves from a balanced state at the coronal base to an imbalanced state, with outward fluctuations dominating, at and beyond the Alfvén surface, i.e., inward turbulent fluctuations are dissipated preferentially; (2) the initially imbalanced slab component remains imbalanced throughout the solar corona, being dominated by outwardly propagating Alfvén waves, and wave reflection is weak; (3) quasi-2D turbulence becomes increasingly magnetized, and beyond

, the kinetic energy is mainly in slab fluctuations; (4) there is no accumulation of inward energy at the Alfvén surface; (5) inertial range quasi-2D rather than slab fluctuations are preferentially dissipated within

; and (6) turbulent dissipation of quasi-2D fluctuations is sufficient to heat the corona to temperatures

K within

Abstract
The multiplexing capability of slitless spectroscopy is a powerful asset in creating large spectroscopic data sets, but issues such as spectral confusion make the interpretation of the data challenging. Here we present a new method to search for emission lines in the slitless spectroscopic data from the 3D-HST survey utilizing the Wide-Field Camera 3 on board the Hubble Space Telescope. Using a novel statistical technique, we can detect compact (extended) emission lines at 90% completeness down to fluxes of

, close to the noise level of the grism exposures, for objects detected in the deep ancillary photometric data. Unlike previous methods, the Bayesian nature allows for probabilistic line identifications, namely redshift estimates, based on secondary emission line detections and/or photometric redshift priors. As a first application, we measure the comoving number density of Extreme Emission Line Galaxies (restframe [O iii] λ5007 equivalent widths in excess of 500 Å). We find that these galaxies are nearly 10× more common above z ∼ 1.5 than at z ≲ 0.5. With upcoming large grism surveys such as Euclid and WFIRST, as well as grisms featured prominently on the NIRISS and NIRCam instruments on the James Webb Space Telescope, methods like the one presented here will be crucial for constructing emission line redshift catalogs in an automated and well-understood manner.
The Variable Fast Soft X-Ray Wind in PG 1211+143
Authors: Reeves J. N. , Lobban A. , Pounds K. A. 
Published: February 2018

Abstract
The analysis of a series of seven observations of the nearby (z = 0.0809) QSO PG 1211+143, taken with the Reflection Grating Spectrometer (RGS) onboard XMM-Newton in 2014, are presented. The high-resolution soft X-ray spectrum, with a total exposure exceeding 600 ks, shows a series of blueshifted absorption lines from the He and H-like transitions of N, O, and Ne, as well as from L-shell Fe. The strongest absorption lines are all systematically blueshifted by −0.06c, originating in two absorption zones from low- and high-ionization gas. Both zones are variable on timescales of days, with the variations in absorber opacity effectively explained by either column density changes or the absorber ionization responding directly to the continuum flux. We find that the soft X-ray absorbers probably exist in a two-phase wind at a radial distance of ∼1017–1018 cm from the black hole with the lower-ionization gas as denser clumps embedded within a higher-ionization outflow. The overall mass outflow rate of the soft X-ray wind may be as high as

yr−1, close to the Eddington rate for PG 1211+143 and similar to that previously deduced from the Fe K absorption.

Abstract
We present the K2 light curves of a large sample of untargeted main-belt asteroids (MBAs) detected with the Kepler Space Telescope. The asteroids were observed within the Uranus superstamp, a relatively large, continuous field with a low stellar background designed to cover the planet Uranus and its moons during Campaign 8 of the K2 mission. The superstamp offered the possibility of obtaining precise, uninterrupted light curves of a large number of MBAs and thus determining unambiguous rotation rates for them. We obtained photometry for 608 MBAs, and were able to determine or estimate rotation rates for 90 targets, of which 86 had no known values before. In an additional 16 targets we detected incomplete cycles and/or eclipse-like events. We found the median rotation rate to be significantly longer than that of the ground-based observations, indicating that the latter are biased toward shorter rotation rates. Our study highlights the need and benefits of further continuous photometry of asteroids.

À partir du cadre théorique de la niche d’activité professionnelle et d’études effectuées au Québec, un portrait des pratiques et représentations du travail avec interprètes dans les soins est dressé. Ce portrait est d’abord fait pour les contextes non sensibles aux dimensions linguistiques et culturelles des soins. Il est ensuite dépeint plus en détail avec deux études menées en contextes sensibles. Cette comparaison permet de mettre en évidence les niveaux de contexte qu’il est nécessaire de prendre en compte pour l’intégration des interprètes dans les équipes de soins et pour établir une collaboration interprète-praticien de qualité : politique, institutionnelle (qui inclut les dimensions structurelle et collaborative), de formation et déontologique. Pour chacun d’eux, les conditions idéales pour établir une collaboration interprète-praticien-usager constructive sont décrites.

Abstract. Accurate and long-term rainfall estimates are the main inputs for several applications, from crop modeling to climate analysis. In this study, we present a new rainfall data set (SM2RAIN-CCI) obtained from the inversion of the satellite soil moisture (SM) observations derived from the ESA Climate Change Initiative (CCI) via SM2RAIN (Brocca et al., 2014). Daily rainfall estimates are generated for an 18-year long period (1998–2015), with a spatial sampling of 0.25° on a global scale, and are based on the integration of the ACTIVE and the PASSIVE ESA CCI SM data sets.The quality of the SM2RAIN-CCI rainfall data set is evaluated by comparing it with two state-of-the-art rainfall satellite products, i.e. the Tropical Measurement Mission Multi-satellite Precipitation Analysis 3B42 real-time product (TMPA 3B42RT) and the Climate Prediction Center Morphing Technique (CMORPH), and one modeled data set (ERA-Interim). A quality check is carried out on a global scale at 1° of spatial sampling and 5 days of temporal sampling by comparing these products with the gauge-based Global Precipitation Climatology Centre Full Data Daily (GPCC-FDD) product. SM2RAIN-CCI shows relatively good results in terms of correlation coefficient (median value  >  0.56), root mean square difference (RMSD, median value  <  10.34 mm over 5 days) and bias (median value  <  −14.44 %) during the evaluation period. The validation has been carried out at original resolution (0.25°) over Europe, Australia and five other areas worldwide to test the capabilities of the data set to correctly identify rainfall events under different climate and precipitation regimes.The SM2RAIN-CCI rainfall data set is freely available at https://doi.org/10.5281/zenodo.846259.

Published: February 2018

En el presente trabajo abordamos la figura del eslogan, como elemento destacado de la comunicación publicitaria, sobre todo en relación al papel que puede desempeñar en la formación o modificación de actitudes del consumidor hacía la marca. Para ello, se presenta un estudio con el que se trata de comprobar si la presentación de determinadas marcas, junto a su eslogan correspondiente, da como resultado unas medidas actitudinales más favorables a dichas marcas que las que se pudieran obtener ante la presentación de las mismas sin estar acompañadas por sus eslóganes. Finalmente, se deja patente la dificultad empírica que encontra­ mos en este ámbito, así como el largo camino que queda por trazar y recorrer en la investigación científica del proceso comunicativo publicitario si queremos enten­ der más profundamente el mecanismo de funcionamiento no ya del eslogan, sino de todo el mensaje publicitario.

How Light‐Absorbing Properties of Organic Aerosol Modify the Asian Summer Monsoon Rainfall?
Authors: Chu Jung‐Eun , Kim Kyu‐Myong , Lau William K. M. , Ha Kyung‐Ja 
Published: February 2018

AbstractLight‐absorbing aerosols not only contribute to Earth's radiative balance but also influence regional climate by cooling the surface and warming the atmosphere. Following recent suggestions that organic aerosols (OAs) absorb substantial amount of solar radiation, we examine the role of light‐absorbing properties of OA on Asian summer monsoon rainfall redistribution using observational data and an atmospheric general circulation model experiment. Results suggest that the enhanced light absorption by OA in Southeast Asia and Northeast Asia is associated with the advance of the Indian summer monsoon in May and the southward shift of East Asian summer monsoon rainband in June. The rainfall redistribution in May is induced by elevated orographic effect with a warm‐core upper‐level anticyclone and surface warming of 1–2 °C over the Tibetan Plateau, whereas that of the East Asian summer monsoon in June is formed by stable conditions associated with surface cooling and atmospheric warming around 30°N.
Adaptive Node Parameterization for Dynamic Determination of Boundaries and Nodes of GNSS Tomographic Models
Authors: Ding N. , Zhang S. B. , Wu S. Q. , Wang X. M. , Zhang K. F. 
Published: February 2018

AbstractWater vapor is one of the primary greenhouse gases and significantly impacts the atmosphere. Water vapor is the most active meteorological element and varies rapidly in both the spatial and temporal domains. As a promising means, Global Navigation Satellite Systems (GNSS) tomography has been used to construct the 3D distribution of water vapor in high resolutions. Currently, in the most commonly used node parameterization approaches, the region for the 3D modeling has a preset fixed regular shape for all tomographic epochs. As a result, too many unknown parameters need to be estimated and thus to degrade the performance of the tomographic solution. In this study, an innovative node parameterization approach using a combination of three meshing techniques to dynamically adjust both the boundary of the tomographic region and the position of nodes at each tomographic epoch is proposed. The three meshing techniques were boundary extraction, Delaunay triangulation, and force‐displacement algorithm. The performance of the tomographic model resulting from the new approach was tested using one month GNSS data in May 2015 from the Hong Kong GNSS network and was compared against that of the conventional node parameterization approach. The reference for the validation of the accuracy of the test results were the radiosonde measurements from King's Park Meteorological Station (HKKP) in Hong Kong. Results showed that in terms of root‐mean‐square error the accuracy of the new approach significantly improved in comparison to the traditional approach.

Published: February 2018

AbstractThis study examined 34 lightning flashes within four separate thundersnow events derived from lightning mapping arrays (LMAs) in northern Alabama, central Oklahoma, and Washington DC. The goals were to characterize the in‐cloud component of each lightning flash, as well as the correspondence between the LMA observations and lightning data taken from national lightning networks like the National Lightning Detection Network (NLDN). Individual flashes were examined in detail to highlight several observations within the data set. The study results demonstrated that the structures of these flashes were primarily normal polarity. The mean area encompassed by this set of flashes is 375 km2, with a maximum flash extent of 2,300 km2, a minimum of 3 km2, and a median of 128 km2. An average of 2.29 NLDN flashes were recorded per LMA‐derived lightning flash. A maximum of 11 NLDN flashes were recorded in association with a single LMA‐derived flash on 10 January 2011. Additionally, seven of the 34 flashes in the study contain zero NLDN‐identified flashes. Eleven of the 34 flashes initiated from tall human‐made objects (e.g., communication towers). In at least six lightning flashes, the NLDN detected a return stroke from the cloud back to the tower and not the initial upward leader. This study also discusses lightning's interaction with the human‐built environment and provides an example of lightning within heavy snowfall observed by Geostationary Operational Environmental Satellite‐16's Geostationary Lightning Mapper.

Published: February 2018

AbstractAmyotrophic lateral sclerosis 8 (ALS8) is a rare progressive neurodegenerative disease resulting from mutation in the gene for vesicle‐associated membrane protein‐associated protein B. We evaluated a North American patient using exome sequencing, and identified a P56S mutation. The disease protein had similar subcellular localization and expression levels in the patient and control fibroblasts. Patient fibroblasts showed increased basal endoplasmic reticulum stress and dysfunction of nucleocytoplasmic transport as evidenced by impaired Ran trafficking. This finding extends the identification of ALS8 into North America, and indicates a cellular defect similar to other forms of hereditary motor neuron disease.
