Abstract
We present a catalog of 9888 M, L and T dwarfs detected in the Pan-STARRS1 3π Survey (PS1), covering three-quarters of the sky. Our catalog contains nearly all known objects of spectral types L0–T2 in the PS1 field, with objects as early as M0 and as late as T9, and includes PS1, 2MASS, AllWISE, and Gaia DR1 photometry. We analyze the different types of photometry reported by PS1 and use two types in our catalog in order to maximize both depth and accuracy. Using parallaxes from the literature, we construct empirical SEDs for field ultracool dwarfs spanning 0.5–12 μm. We determine typical colors of M0–T9 dwarfs and highlight the distinctive colors of subdwarfs and young objects. We combine astrometry from PS1, 2MASS, and Gaia DR1 to calculate new proper motions for our catalog. We achieve a median precision of 2.9 mas yr−1, a factor of ≈3−10 improvement over previous large catalogs. Our catalog contains proper motions for 2405 M6–T9 dwarfs and includes the largest set of homogeneous proper motions for L and T dwarfs published to date, 406 objects for which there were no previous measurements, and 1176 objects for which we improve upon previous literature values. We analyze the kinematics of ultracool dwarfs in our catalog and find evidence that bluer but otherwise generic late-M and L field dwarfs (i.e., not subdwarfs) tend to have tangential velocities higher than those of typical field objects. With the public release of the PS1 data, this survey will continue to be an essential tool for characterizing the ultracool dwarf population.
Multidimensional Models of Type Ia Supernova Nebular Spectra: Strong Emission Lines from Stripped Companion Gas Rule Out Classic Single-degenerate Systems
Authors: Botyánszki János , Kasen Daniel , Plewa Tomasz 
Published: December 2017

Abstract
The classic single-degenerate model for the progenitors of Type Ia supernova (SN Ia) predicts that the supernova ejecta should be enriched with solar-like abundance material stripped from the companion star. Spectroscopic observations of normal SNe Ia at late times, however, have not resulted in definite detection of hydrogen. In this Letter, we study line formation in SNe Ia at nebular times using non-LTE spectral modeling. We present, for the first time, multidimensional radiative transfer calculations of SNe Ia with stripped material mixed in the ejecta core, based on hydrodynamical simulations of ejecta–companion interaction. We find that interaction models with main-sequence companions produce significant Hα emission at late times, ruling out these types of binaries being viable progenitors of SNe Ia. We also predict significant He i line emission at optical and near-infrared wavelengths for both hydrogen-rich or helium-rich material, providing an additional observational probe of stripped ejecta. We produce models with reduced stripped masses and find a more stringent mass limit of M

Bright Merger-nova Emission Powered by Magnetic Wind from a Newborn Black Hole

Published: December 2017

Abstract
Mergers of neutron star–neutron star (NS–NS) or neutron star–black hole (NS–BH) binaries are candidate sources of gravitational waves (GWs). At least a fraction of the merger remnants should be a stellar mass BH with sub-relativistic ejecta. A collimated jet is launched via the Blandford–Znajek mechanism from the central BH to trigger a short gamma-ray burst (sGRB). At the same time, a near-isotropic wind may be driven by the Blandford–Payne mechanism (BP). In previous work, additional energy injection to the ejecta from the BP mechanism was ignored, and radioactive decay has long been thought to be the main source of the kilonova energy. In this Letter, we propose that the wind driven by the BP mechanism from the newborn BH’s disk can heat up and push the ejecta during the prompt emission phase or even at late times when there is fall-back accretion. Such a BP-powered merger-nova could be bright in the optical band even for a low-luminosity sGRB. The detection of a GW merger event with a BH clearly identified as a remnant, accompanied by a bright merger-nova, would provide robust confirmation of our model.

La Chine entre dans une phase ambitieuse de nationalisme « aux caractéristiques chinoises ». Les défis que doit relever la Chine et son leader restent cependant nombreux, et l’issue de la lutte des systèmes qui se met en place entre la Chine et l’Occident reste incertaine.
La presse officielle chinoise à l’ère des nouveaux médias
Authors: He Qian 
Published: December 2017

Les médias officiels chinois sont contraints par les réseaux sociaux à s’adapter et à jouer un jeu concurrentiel auquel ils ne sont pas habitués. Amenés par de nouvelles règles du jeu à descendre dans une arène qui n’est pas la leur, ils sont souvent distancés par des opérateurs privés. S’ils bénéficient des subventions de l’État pour affronter dans de bonnes conditions la concurrence, la nécessité d’être encadrée par les directives qui régissent l’action des médias officiels constitue un obstacle dans cette lutte acharnée pour séduire les internautes chinois. La notion de « nouvelles faussées » devient un enjeu pour les médias officiels pour reprendre l’avantage et restaurer leur autorité menacée.
L’atlantisme est-il un anachronisme ? Le nécessaire débat sur l’avenir de la politique étrangère de la France
Authors: Courmont Barthélemy 
Published: December 2017

L’arrivée au pouvoir d’Emmanuel Macron bouleverse profondément le paysage politique français. Elle annonce également une refonte du projet européen, chère au président de la République, et une tentative de réaffirmation d’une politique étrangère indépendante, qu’il a exprimée à plusieurs occasions. Dans un contexte international également marqué par un risque de retrait des États-Unis et un isolement du Royaume-Uni, mais aussi par l’émergence de nouveaux acteurs politico-stratégiques et d’enjeux sécuritaires globaux, l’atlantisme comme grille de lecture trouve-t-il encore sa pertinence dans son accompagnement de la politique étrangère française ? Plus que jamais, la question doit être posée, intégrer des éléments de réflexion libérés de tout dogme et être élargie au monde universitaire et aux think tanks .
Consideration of Problem-Based Learning in Athletic Training Education
Authors: Gillette Cordial M. 
Published: December 2017

Context:
Athletic training educators are faced with the tasks of assessing learning styles, preparing and delivering content, and assessing student learning. Within content delivery, some educators may subscribe to certain learning theories and teaching strategies. One teaching strategy that holds potential for athletic training education is problem-based learning, which is grounded in cognitive theory and aligns with the way in which athletic training students learn by constructing knowledge based on previous experiences.

Objective:
To describe problem-based learning, the theoretical basis for using problem-based learning in athletic training education, and provide examples of incorporating problem-based learning activities into an evaluation course.

Background:
Problem-based learning was first introduced at McMaster University in an attempt to better transition between what medical students were learning in the classroom and what they were experiencing in their clinical settings. Problem-based learning has been studied and found to be effective in health care education and can be considered by athletic training educators.

Description:
Problem-based learning is a philosophy as well as a teaching strategy that uses problem solving to learn both content and clinical skills. Students work independently and in small groups to acquire knowledge through problem solving. Problem-based learning challenges the idea that students need a reservoir of knowledge before being able to solve a complex problem.

Clinical Advantage(s):
Based on theory and research in health care education, problem-based learning can be used in athletic training education to improve students' abilities to construct knowledge, to be active learners, to collaborate, and to give them the skills to be lifelong learners.

Conclusion(s):
Athletic training educators can consider implementing problem-based learning into their curriculums to integrate the learning of content and clinical skills.

ABSTRACT
The esthetic and functional rehabilitation of the patients with palatal defects using obturator poses challenge to the clinician. The use of existing teeth along with implants helps in providing good retention, support, and stability to the prosthesis. Ball-socket type of attachments offer efficient, yet economical alternative to these patients. This case report describes management of a hemimaxillectomy adult patient with a class II palatal defect using tooth implant-supported obturator. Osseointegrated implants and direct overdenture post with ball-socket type of attachments were used to construct a definitive obturator for prosthetic rehabilitation of this patient.

Materiales y métodos: Los embriones se obtuvieron de frutos maduros de A. aculeata, recolectados en individuos de una población nativa, próxima a la ciudad de San Lorenzo, Departamento Central, Paraguay. El estudio morfoanatómico se hizo mediante la fijación, deshidratación e inclusión de los embriones en bloques de resina y análisis cualitativo mediante microscopía. Resultados y discusión: El embrión es pequeño de color amarillo verdoso y de forma lanceolada. En el extremo proximal se localiza el cotiledón, y en el distal, el limbo o haustorio. El embrión presenta una hendidura longitudinal o ventana cotiledonar que permitirá la emergencia de la plántula (radicula y plúmula). La plúmula, bien diferenciada, está situada en ángulo con respecto al eje longitudinal del embrión; en forma opuesta se encuentra la zona meristemática, donde se desarrollará la radícula. La plúmula consta de dos primordios foliares y un ápice, con el esbozo de un tercer primordio. Conclusión: En general, el embrión de A. aculeata es semejante al de otras palmas del mismo grupo, en cuanto a forma e inclusión en el endosperma.
Derecho, soberanía y Pluralismo constitucional en el contexto de la globalización. Un análisis de sus tensiones y complejidades | Law, Sovereignty and Legal Pluralism in The Context of Globalization. An Analysis of its Tensions and Complexities
Authors: Martínez de Bringas Asier 
Published: December 2017

Resumen: El texto realiza un análisis de las tendencias del Derecho en la globalización, como consecuencia de las transformaciones operadas en las maneras de entender el sentido y la naturaleza de la soberanía, poniendo énfasis en la dimensión paradójica que presenta el derecho en la UE en relación-tensión con el derecho constitucional de los Estados. Las relaciones jurídicas se han hecho mucho más complejas como consecuencia de la irrupción del inevitable pluralismo en la manera de entender el Derecho. Es lo que vamos a denominar como Pluralismo Constitucional, que en sus propias maneras de producción, distribución y aplicación opera según la lógica de la red, haciendo más complejo e interdisciplinar la interpretación de cualquier práctica jurídica.

Abstract: In this paper we will proceed with an analysis of trends in the globalization of law as a result of the transformations in the ways of understanding the meaning and nature of sovereignty, emphasizing the paradoxical dimension has the right in the EU in tension with the constitutional right of states. The legal relationships have become much more complex as a result of the inevitable emergence pluralism in the way of understanding the law. It is what we call as Constitutional Pluralism, which in its own ways of production, distribution and application operates as a network, making it more complex and interdisciplinary the interpretation of any legal practice. Some of the changes and transformations that occur as a result of this new paradigm of Legal Pluralism will be some of the scope of this writing.
Trends in reconstruction of three nucleus-encoded, plastid-localized pathways for the heme, chlorophyll a and isopentenyl diphosphate biosynthesises in two separate dinoflagellate lineages bearing non-canonical plastids
Authors: Matsuo Eriko , Inagaki Yuji 
Published: December 2017

Background: The ancestral dinoflagellate most likely established a peridinin-containing plastid, which have been inherited to the extant photosynthetic descendants. However, kareniacean dinoflagellates and Lepidodinium species were known to bear “non-canonical” plastids lacking peridinin, which were established through haptophyte and a green algal endosymbioses, respectively. For plastid function and maintenance, the aforementioned dinoflagellates were known to use nucleus-encoded proteins vertically inherited from the ancestral dinoflagellates (vertically inherited- or VI-type), and those acquired from non-dinoflagellate organisms (including the endosymbiont). These observations indicated that the proteomes of the non-canonical plastids derived from a haptophyte and a green alga were modified by “exogenous” genes acquired from non-dinoflagellate organisms. However, there was no systematic evaluation addressing how “exogenous” genes reshaped individual metabolic pathways localized in a non-canonical plastid.
Results: In this study, we surveyed transcriptomic data from two kareniacean species (Karenia brevis and Karlodinium veneficum) and Lepidodinium chlorophorum, and identified proteins involved in three plastid metabolic pathways synthesizing chlorophyll a (Chl a), heme and isoprene. The origins of the individual proteins of our interest were investigated, and assessed how the three pathways were modified before and after the algal endosymbioses, which gave rise to the current non-canonical plastids. We observed a clear difference in the contribution of VI-type proteins across the three pathways. In both Karenia/Karlodinium and Lepidodinium, we observed a substantial contribution of VI-type proteins to the isoprene and heme biosynthesises. In sharp contrast, VI-type protein was barely detected in the Chl a biosynthesis in the three dinoflagellates.
Discussion: Pioneering works hypothesized that the ancestral kareniacean species had lost the photosynthetic activity prior to haptophyte endosymbiosis. The absence of VI-type proteins in the Chl a biosynthetic pathway in Karenia or Karlodinium is in good agreement with the putative non-photosynthetic nature proposed for their ancestor. The dominance of proteins with haptophyte origin in the Karenia/Karlodinium pathway suggests that their ancestor rebuilt the particular pathway by genes acquired from the endosymbiont. Likewise, we here propose that the ancestral Lepidodinium likely experienced a non-photosynthetic period and discarded the entire Chl a biosynthetic pathway prior to the green algal endosymbiosis. Nevertheless, Lepidodinium rebuilt the pathway by genes transferred from phylogenetically diverse organisms, rather than the green algal endosymbiont. We explore the reasons why green algal genes were barely utilized to reconstruct the Lepidodinium pathway.
Fuel‐Free Bio‐photoelectrochemical Cells Based on a Water/Oxygen Circulation System with a Ni:FeOOH/BiVO4 Photoanode

Published: December 2017

AbstractA bio‐photoelectrochemical cell (BPEC) based on a fuel‐free self‐circulation water–oxygen–water system was fabricated. It consists of Ni:FeOOH modified n‐type bismuth vanadate (BiVO4) photoanode and laccase catalyzed biocathode. In this BPEC, irradiation of the photoanode generates photocurrent for photo‐oxidation of water to oxygen, which is reduced to water again at the laccase biocathode. Of note, the by‐products of two electrode reactions could continue to be reacted, which means the H2O and O2 molecules are retained in an infinite loop of water–oxygen–water without any sacrificial chemical components. As a result, the assembled fuel‐free BPEC exhibits good performance with an open‐circuit potential of 0.97 V and a maximum power density of 205 μW cm−2 at 0.44 V. This BPEC based on a self‐circulation system offers a fuel‐free model to enhance multiple energy conversion and application in reality.
A New Portal to SuFEx Click Chemistry: A Stable Fluorosulfuryl Imidazolium Salt Emerging as an “F−SO2+” Donor of Unprecedented Reactivity, Selectivity, and Scope

Published: December 2017

AbstractSulfuryl fluoride, SO2F2, has been found to derivatize phenols in all kinds of environments, even those in highly functional molecules. We now report that a solid fluorosulfuryl imidazolium triflate salt delivers the same “F−SO2+” fragment to Nu−H acceptor groups in the substrates. However, this triflate salt is a far more reactive fluorosulfurylating agent than SO2F2 and displays selectivity preferences of its own. Moreover, the new azolium triflate reagent reacts once with primary amines and anilines before the reaction stops. On the other hand, with triethylamine and two equivalents of the “F−SO2+” donor present, it proceeds on to the bis(fluorosulfuryl)imides in good yield—two important conversions that we have never seen with sulfuryl fluoride as the electrophile.

AbstractChemical conjugation between hydrophilic and hydrophobic components is difficult because of their extremely different solubility. Herein, we report a new versatile method with a solid‐phase‐assisted disulfide ligation to overcome the difficulty of conjugation attributed to solubility. The method involves two steps in a one‐pot process: 1) loading of a hydrophobic molecule onto a resin in an organic solvent, and 2) release of the solid‐supported hydrophobic molecule as a conjugate with a hydrophilic molecule into an aqueous solvent. This strategy allows the use of a suitable solvent system for the substrates in each step. Conjugates of a water‐insoluble drug, plinabulin, with hydrophilic carriers that could not be prepared by solution‐phase reactions were obtained in moderate yields (29–45 %). This strategy is widely applicable to the conjugation of compounds with solubility problems.
Stabilization of the Reductase Domain in the Catalytically Self‐Sufficient Cytochrome P450BM3 by Consensus‐Guided Mutagenesis

Published: December 2017

AbstractThe multidomain, catalytically self‐sufficient cytochrome P450 BM‐3 from Bacillus megaterium (P450BM3) constitutes a versatile enzyme for the oxyfunctionalization of organic molecules and natural products. However, the limited stability of the diflavin reductase domain limits the utility of this enzyme for synthetic applications. In this work, a consensus‐guided mutagenesis approach was applied to enhance the thermal stability of the reductase domain of P450BM3. Upon phylogenetic analysis of a set of distantly related P450s (>38 % identity), a total of 14 amino acid substitutions were identified and evaluated in terms of their stabilizing effects relative to the wild‐type reductase domain. Recombination of the six most stabilizing mutations generated two thermostable variants featuring up to tenfold longer half‐lives at 50 °C and increased catalytic performance at elevated temperatures. Further characterization of the engineered P450BM3 variants indicated that the introduced mutations increased the thermal stability of the FAD‐binding domain and that the optimal temperature (Topt) of the enzyme had shifted from 25 to 40 °C. This work demonstrates the effectiveness of consensus mutagenesis for enhancing the stability of the reductase component of a multidomain P450. The stabilized P450BM3 variants developed here could potentially provide more robust scaffolds for the engineering of oxidation biocatalysts.
