An Independent Asteroseismic Analysis of the Fundamental Parameters and Internal Structure of the Solar-like Oscillator KIC 6225718
Authors: Wu Tao , Li Yan 
Published: August 2017

Abstract
Asteroseismology is a useful tool that is usually used to probe stellar interiors and to determine stellar fundamental parameters, such as stellar mass, radius, and surface gravity. In order to probe stellar interiors, making comparisons between observations and models is usually used with the

χ

-minimization method. The work of Wu & Li reported that the best parameter determined by the

χ

2

-matching process is the acoustic radius for pure p-mode oscillations. In the present work, based on the theoretical calculations of Wu & Li, we will independently analyze the seismic observations of KIC 6225718 to determine its fundamental parameters and to investigate its interior properties. First, in order to test the method, we use it in the Sun to determine its fundamental parameters and to investigate interiors. Second, we independently determine the fundamental parameters of KIC 6225718 without any other non-seismic constraint. Therefore, those determined fundamental parameters are independent of those determined by other methods. They can be regarded as independent references in other analyses. Finally, we analyze the stellar internal structure and find that KIC 6225718 has a convective core with the size of 0.078–0.092

The Formation of IRIS Diagnostics. IX. The Formation of the C i 135.58 NM Line in the Solar Atmosphere
Authors: Lin Hsiao-Hsuan , Carlsson Mats , Leenaarts Jorrit 
Published: August 2017

Abstract
The C i 135.58 nm line is located in the wavelength range of NASA’s Interface Region Imaging Spectrograph (IRIS) small explorer mission. We study the formation and diagnostic potential of this line by means of non local-thermodynamic-equilibrium modeling, employing both 1D and 3D radiation-magnetohydrodynamic models. The C i/C ii ionization balance is strongly influenced by photoionization by Lyα emission. The emission in the C i 135.58 nm line is dominated by a recombination cascade and the line forming region is optically thick. The Doppler shift of the line correlates strongly with the vertical velocity in its line forming region, which is typically located at 1.5 Mm height. With IRIS, the C i 135.58 nm line is usually observed together with the O i 135.56 nm line, and from the Doppler shift of both lines, we obtain the velocity difference between the line forming regions of the two lines. From the ratio of the C i/O i line core intensity, we can determine the distance between the C i and the O i forming layers. Combined with the velocity difference, the velocity gradient at mid-chromospheric heights can be derived. The C i/O i total intensity line ratio is correlated with the inverse of the electron density in the mid-chromosphere. We conclude that the C i 135.58 nm line is an excellent probe of the middle chromosphere by itself, and together with the O i 135.56 nm line the two lines provide even more information, which complements other powerful chromospheric diagnostics of IRIS such as the Mg ii h and k lines and the C ii lines around 133.5 nm.

Abstract
The spatial distribution of oxygen in the interstellar medium of galaxies is the key to understanding how efficiently metals that are synthesized in massive stars can be redistributed across a galaxy. We present here a case study in the nearby spiral galaxy NGC 1365 using 3D optical data obtained in the TYPHOON Program. We find systematic azimuthal variations of the H ii region oxygen abundance imprinted on a negative radial gradient. The 0.2 dex azimuthal variations occur over a wide radial range of 0.3–0.7 R
25 and peak at the two spiral arms in NGC 1365. We show that the azimuthal variations can be explained by two physical processes: gas undergoes localized, sub-kiloparsec-scale self-enrichment when orbiting in the inter-arm region, and experiences efficient, kiloparsec-scale mixing-induced dilution when spiral density waves pass through. We construct a simple chemical evolution model to quantitatively test this picture and find that our toy model can reproduce the observations. This result suggests that the observed abundance variations in NGC 1365 are a snapshot of the dynamical local enrichment of oxygen modulated by spiral-driven, periodic mixing and dilution.
Light-curve Analysis of Ordinary Type IIP Supernovae Based on Neutrino-driven Explosion Simulations in Three Dimensions
Authors: Utrobin V. P. , Wongwathanarat A. , Janka H.-Th. , Müller E. 
Published: August 2017

Abstract
Type II-plateau supernovae (SNe IIP) are the most numerous subclass of core-collapse SNe originating from massive stars. In the framework of the neutrino-driven explosion mechanism, we study the properties of the SN outburst for a red supergiant progenitor model and compare the corresponding light curves with observations of the ordinary Type IIP SN 1999em. Three-dimensional (3D) simulations of (parametrically triggered) neutrino-driven explosions are performed with the (explicit, finite-volume, Eulerian, multifluid hydrodynamics) code Prometheus, using a presupernova model of a 15 M
⊙ star as initial data. On approaching homologous expansion, the hydrodynamic and composition variables of the 3D models are mapped to a spherically symmetric configuration, and the simulations are continued with the (implicit, Lagrangian, radiation hydrodynamics) code Crab to follow the evolution of the blast wave during the SN outburst. Our 3D neutrino-driven explosion model with an explosion energy of about

erg produces 56Ni in rough agreement with the amount deduced from fitting the radioactively powered light-curve tail of SN 1999em. The considered presupernova model, 3D explosion simulations, and light-curve calculations can explain the basic observational features of SN 1999em, except for those connected to the presupernova structure of the outer stellar layers. Our 3D simulations show that the distribution of 56Ni-rich matter in velocity space is asymmetric with a strong dipole component that is consistent with the observations of SN 1999em. The monotonic decline in luminosity from the plateau to the radioactive tail in ordinary SNe IIP is a manifestation of the intense turbulent mixing at the He/H composition interface.
James Curran : l’athlète écossais aérien et la légende américaine du coaching
Authors: Adams Iain , Laffage-Cosnier Sébastien 
Published: August 2017

De même que pour beaucoup de coachs professionnels de l’ère édouardienne (1901-1910, sic), il y a très peu de traces de Jimmy Curran dans les documents : il est habituellement décrit comme un ancien athlète professionnel qui a détecté le talent de coureur de Wyndham Halswelle alors qu’il servait dans l’infanterie légère écossaise lors de la guerre des Boers. Curran convainc Halswelle de prendre l’athlétisme au sérieux lorsque le régiment retourne en Angleterre et le coache avec succès dans l’épreuve du 880 yards lors de la compétition militaire en 1904, et lors des deux titres écossais et anglais du 440 yards en 1905. Halswelle a continué en gagnant le controversé 400 mètres aux JO de 1908 à Londres. Curran est parti pour l’Amérique en 1907 laissant son camarade ex-soldat et professionnel Jack Dalziel au coach Halswelle. Aujourd’hui, Curran est célébré en Amérique comme le légendaire coach de Mercersburg Academy qui a été impliqué dans l’entraînement de 13 athlètes olympiques en athlétisme entre 1912 et 1964 ; ils ont gagné six médailles d’or, une d’argent et deux de bronze. Cet article décrit la biographie de Curran en examinant plus particulièrement ses propres relations négociées entre l’amateurisme et le professionnalisme qui s’établissent à partir de l’étude de la bataille entre le système de valeurs de Charterhouse (Public school) et de Sandhurst (école militaire) : la première forme le gentleman amateur lieutenant Halswelle, et la seconde forge l’ouvrier et le militaire (Lancier), le caporal Curran. Le texte prend en compte le désir de Curran de s’expatrier en Amérique en 1907 et sa relation avec Mike Murphy, le coach de l’Université de Pennsylvania, devenu coach en chef de l’équipe olympique US de 1908, qui a recommandé Curran à l’Académie de Mercersburg comme coach d’athlétisme en 1910.
The vision of ‘Dry Bones’ in Ezekiel 37:1–28: Resonating Ezekiel’s message as the African prophet of hope
Authors: Biwul Joel K.T. 
Published: August 2017

Against the background of a disenfranchised and hopeless exilic Israel, Ezekiel received the vision of ‘Dry Bones’, predicting an eschatological resuscitation and resurrection to life and restoration to the land of Yahweh’s covenant people. This article previews the political, social, economic and moral conditions of many African societies as being in a disenfranchised, hopeless exilic state. It nonetheless argues that the theological essence of Ezekiel’s visionary imagery of ‘Dry Bones’ resonates well with such deteriorating and hopeless African societies. It envisages the semblances, relatedness and relevance of Ezekiel’s hope principle of a restorative eschatological theology as a possible reality for Africa’s hopeless present ‘Dry Bones’ state. Upon this hope principle, the article proposes a theological framework of faith against despondency and despair for the realisation of such eschatological reality for Africa. It holds that God is equally capable of displaying his restorative power and sovereignty to reverse the hopeless conditions of African nations in demonstration of his love, compassion and care as he did for the apparently irreparable condition of exilic Israel.

Abstract. Active fault databases are a very powerful and useful tool in seismic hazard assessment, particularly when singular faults are considered seismogenic sources. Active fault databases are also a very relevant source of information for earth scientists, earthquake engineers and even teachers or journalists. Hence, active fault databases should be updated and thoroughly reviewed on a regular basis in order to keep a standard quality and uniformed criteria. Desirably, active fault databases should somehow indicate the quality of the geological data and, particularly, the reliability attributed to crucial fault-seismic parameters, such as maximum magnitude and recurrence interval. In this paper we explain how we tackled these issues during the process of updating and reviewing the Quaternary Active Fault Database of Iberia (QAFI) to its current version 3. We devote particular attention to describing the scheme devised for classifying the quality and representativeness of the geological evidence of Quaternary activity and the accuracy of the slip rate estimation in the database. Subsequently, we use this information as input for a straightforward rating of the level of reliability of maximum magnitude and recurrence interval fault seismic parameters. We conclude that QAFI v.3 is a much better database than version 2 either for proper use in seismic hazard applications or as an informative source for non-specialized users. However, we already envision new improvements for a future update.

Published: August 2017

Genotyping-by-sequencing (GBS) was used to survey genome-wide single-nucleotide polymorphisms (SNPs) in three biparental strawberry (Fragaria× ananassa) populations with the goal of evaluating this technique in a species with a complex octoploid genome. GBS sequence data were aligned to theF. vesca‘Fvb’ reference genome in order to call SNPs. Numbers of polymorphic SNPs per population ranged from 1,163 to 3,190. Linkage maps consisting of 30–65 linkage groups were produced from the SNP sets derived from each parent. The linkage groups covered 99% of theFvbreference genome, with three to seven linkage groups from a given parent aligned to any particular chromosome. A phylogenetic analysis performed using the POLiMAPS pipeline revealed linkage groups that were most similar to ancestral speciesF. vescafor each chromosome. Linkage groups that were most similar to a second ancestral species,F. iinumae, were only resolved forFvb4. The quantity of missing data and heterogeneity in genome coverage inherent in GBS complicated the analysis, but POLiMAPS resolvedF.× ananassachromosomal regions derived from diploid ancestorF. vesca.
Fourteen new species ofOecetisMcLachlan, 1877 (Trichoptera: Leptoceridae) from the Neotropical region
Authors: Quinteiro Fabio B. , Holzenthal Ralph W. 
Published: August 2017

BackgroundThe caddisfly genusOecetiscurrently contains 534 valid species. Its larval stages are found in freshwaters around the world. The adults can be distinguished from other Leptoceridae by the unbranched forewing M vein and the exceptionally long maxillary palps. In the Neotropical region, 55 species ofOecetishave been recorded and most of them can be placed in one of the six species groups known from this biogeographical region: theavara-,falicia-,inconspicua-,punctata-,punctipennis-, andtestacea-groups. More than 50% of the known diversity of NeotropicalOecetishas been described in the past 40 years. Here, we describe an additional 14 new species ofOecetisto further document the diversity of this genus in the Neotropical region.MethodsThe descriptions and illustrations presented here are based on male specimens. Specimens were collected with Malaise traps or ultraviolet light traps. They were preserved in alcohol or pinned as stated in material examined section. Specimens had their genitalia prepared in 85% lactic acid to better observe internal characters and illustrations were aided by the use of a microscope with drawing tube attached.Results and DiscussionThis study raises the number of species ofOecetisin the Neotropics from 55 to 69. Eight of the new species presented here could not be reliably placed in one of the known species groups (Oecetis acuticlaspern. sp.,Oecetis flintin. sp.,Oecetis carinatan. sp.,Oecetis cassicoleatan. sp.,Oecetis blahnikin. sp.,Oecetis gibbosan. sp.,Oecetis licinan. sp., andOecetis pertican. sp.). The others are placed in thepunctata-group (Oecetis bidigitatan. sp.,Oecetis quasipunctatan. sp.),testacea-group (Oecetis plenuspinosan. sp.), andfalicia-group (Oecetis calorin. sp.,Oecetis hastapullan. sp.,Oecetis machaeran. sp.). Most of the diagnostic characters rely on structures of the inferior appendages and phallic apparatus, and the shape of tergum X.

Influence of Superparameterization and a Higher‐Order Turbulence Closure on Rainfall Bias Over Amazonia in Community Atmosphere Model Version 5

Published: August 2017

AbstractWe evaluate the Community Atmosphere Model Version 5 (CAM5) with a higher‐order turbulence closure scheme, named Cloud Layers Unified By Binomials (CLUBB), and a Multiscale Modeling Framework, referred to as the “superparameterization” (SP) with two different microphysics configurations to investigate their influences on rainfall simulations over southern Amazonia. The two different microphysics configurations in SP are the one‐moment cloud microphysics without aerosol treatment (SP1) and two‐moment cloud microphysics coupled with aerosol treatment (SP2). Results show that both SP2 and CLUBB effectively reduce the low biases of rainfall, mainly during the wet season, and reduce low biases of humidity in the lower troposphere with further reduced shallow clouds and increased surface solar flux. These changes increase moist static energy in the lower atmosphere and contribute to stronger convection and more rainfall. SP2 appears to realistically capture the observed increase of relative humidity prior to deep convection, and it significantly increases rainfall in the afternoon; CLUBB significantly delays the afternoon peak rainfall and produces more precipitation in the early morning, due to more gradual transition between shallow and deep convection. In CAM5 and CAM5 with CLUBB, occurrence of more deep convection appears to be a result of stronger heating rather than higher relative humidity.
Sodium‐Salt‐Promoted Growth of Self‐Supported Copper Oxides with Comparative Supercapacitive Properties
Authors: Chen Jun Song , Huang Song Peng , Xu Le , Blackwood Daniel John 
Published: August 2017

AbstractIn this work, we developed a facile hydrothermal system to synthesize self‐supported copper oxides with different nanostructures. In this system, we used copper foam as both the substrate and the copper source, and selected a wide range of sodium salts to serve as directing agents, promoting the formation of copper oxide with different nanostructures. We first show that, at 30 mM of sodium fluoride, we can successfully grow nanocubes on the copper foam substrate that comprise both CuO and Cu2O. Such a mixed composition is unique among the investigated salts. However, if a lower concentration of NaF or a different salt is used, Cu2O nanocrystals of different structures, such as nanoplatelets or irregular particles, can be obtained. When these samples were tested in supercapacitors, they demonstrated contrasting pseudocapacitive properties where the initial mixed Cu2O/CuO nanocube sample demonstrated a very stable reversible capacitance of about 400 mF cm−2 for 1600 cycles. This is significantly higher than that for the other samples, as well as advantageous compared to other copper‐oxide‐based electrode materials. The impedance analysis suggested that such a performance could be attributed to the low diffusion resistance of this sample.
