The Dynamics of Truncated Black Hole Accretion Disks. I. Viscous Hydrodynamic Case
Authors: Hogg J. Drew , Reynolds Christopher S. 
Published: July 2017

Abstract
Truncated accretion disks are commonly invoked to explain the spectro-temporal variability in accreting black holes in both small systems, i.e., state transitions in galactic black hole binaries (GBHBs), and large systems, i.e., low-luminosity active galactic nuclei (LLAGNs). In the canonical truncated disk model of moderately low accretion rate systems, gas in the inner region of the accretion disk occupies a hot, radiatively inefficient phase, which leads to a geometrically thick disk, while the gas in the outer region occupies a cooler, radiatively efficient phase that resides in the standard geometrically thin disk. Observationally, there is strong empirical evidence to support this phenomenological model, but a detailed understanding of the dynamics of truncated disks is lacking. We present a well-resolved viscous, hydrodynamic simulation that uses an ad hoc cooling prescription to drive a thermal instability and, hence, produce the first sustained truncated accretion disk. With this simulation, we perform a study of the dynamics, angular momentum transport, and energetics of a truncated disk. We find that the time variability introduced by the quasi-periodic transition of gas from efficient cooling to inefficient cooling impacts the evolution of the simulated disk. A consequence of the thermal instability is that an outflow is launched from the hot/cold gas interface, which drives large, sub-Keplerian convective cells into the disk atmosphere. The convective cells introduce a viscous θ − ϕ stress that is less than the generic r − ϕ viscous stress component, but greatly influences the evolution of the disk. In the truncated disk, we find that the bulk of the accreted gas is in the hot phase.

Abstract
For lensed galaxy SGAS J111020.0+645950.8 at redshift z = 2.481, which is magnified by a factor of 28 ± 8, we analyze the morphology of star formation, as traced by rest-frame ultraviolet emission, in both the highly magnified source plane and simulations of how this galaxy would appear without lensing magnification. Were this galaxy not lensed, but rather drawn from a Hubble Space Telescope deep field, we would conclude that almost all its star formation arises from an exponential disk (Sérsic index of 1.0 ± 0.4) with an effective radius of

measured from two-dimensional fitting to F606W using Galfit, and

measured by fitting a radial profile to F606W elliptical isophotes. At the normal spatial resolution of the deep fields, there is no sign of clumpy star formation within SGAS J111020.0+645950.8. However, the enhanced spatial resolution enabled by gravitational lensing tells a very different story; much of the star formation arises in two dozen clumps with sizes of r = 30–50 pc spread across the 7 kpc length of the galaxy. The color and spatial distribution of the diffuse component suggests that still-smaller clumps are unresolved. Despite this clumpy, messy morphology, the radial profile is still well-characterized by an exponential profile. In this lensed galaxy, stars are forming in complexes with sizes well below 100 pc; such sizes are wholly unexplored by surveys of galaxy evolution at

Abstract
We present measurements of the surface density of star formation, the star-forming clump luminosity function, and the clump size distribution function, for the lensed galaxy SGAS J111020.0+645950.8 at a redshift of z = 2.481. The physical size scales that we probe, radii r = 30–50 pc, are considerably smaller scales than have yet been studied at these redshifts. The star formation surface density we find within these small clumps is consistent with surface densities measured previously for other lensed galaxies at similar redshift. Twenty-two percent of the rest-frame ultraviolet light in this lensed galaxy arises from small clumps, with

pc. Within the range of overlap, the clump luminosity function measured for this lensed galaxy is remarkably similar to those of

galaxies. In this galaxy, star-forming regions smaller than 100 pc—physical scales not usually resolved at these redshifts by current telescopes—are important locations of star formation in the distant universe. If this galaxy is representative, this may contradict the theoretical picture in which the critical size scale for star formation in the distant universe is of the order of 1 kpc. Instead, our results suggest that current telescopes have not yet resolved the critical size scales of star-forming activity in galaxies over most of cosmic time.

Published: July 2017

PURPOSE:
To present the Tomographic and Biomechanical Index (TBI), which combines Scheimpflugbased corneal tomography and biomechanics for enhancing ectasia detection.

METHODS:
Patients from different continents were retrospectively studied. The normal group included 1 eye randomly selected from 480 patients with normal corneas and the keratoconus group included 1 eye randomly selected from 204 patients with keratoconus. There were two groups: 72 ectatic eyes with no surgery from 94 patients with very asymmetric ectasia (VAE-E group) and the fellow eyes of these patients with normal topography (VAE-NT group). Pentacam HR and Corvis ST (Oculus Optikgeräte GmbH, Wetzlar, Germany) parameters were analyzed and combined using different artificial intelligence methods. The accuracies for detecting ectasia of the Belin/Ambrósio Deviation (BAD-D) and Corvis Biomechanical Index (CBI) were compared to the TBI, considering the areas under receiver operating characteristic curves (AUROCs).

RESULTS:

The random forest method with leave-one-out cross-validation (RF/LOOCV) provided the best artificial intelligence model. The AUROC for detecting ectasia (keratoconus, VAE-E, and VAE-NT groups) of the TBI was 0.996, which was statistically higher (DeLong et al.,
P
< .001) than the BAD-D (0.956) and CBI (0.936). The TBI cut-off value of 0.79 provided 100% sensitivity for detecting clinical ectasia (keratoconus and VAE-E groups) with 100% specificity. The AUROCs for the TBI, BAD-D, and CBI were 0.985, 0.839, and 0.822 in the VAE-NT group (DeLong et al.,
P
< .001). An optimized TBI cut-off value of 0.29 provided 90.4% sensitivity with 96% specificity in the VAE-NT group.

CONCLUSIONS:
The TBI generated by the RF/LOOCV provided greater accuracy for detecting ectasia than other techniques. The TBI was sensitive for detecting subclinical (fruste) ectasia among eyes with normal topography in very asymmetric patients. The TBI may also confirm unilateral ectasia, potentially characterizing the inherent ectasia susceptibility of the cornea, which should be the subject of future studies.

Puzzling the Jesus of the Parables: A response to Ruben Zimmermann
Authors: Howes Llewellyn 
Published: July 2017

This article responds to Ruben Zimmermann’s latest book, Puzzling the Parables of Jesus (2015). In particular, one aspect of his proposed method is challenged, namely, his conscious attempt to do away with considerations of the pre-Easter context when interpreting the parables. The article finishes by proposing a variant methodology of parable interpretation, featuring the parable of the Good Samaritan as a working example.
The empirical relationship between the managerial conduct and internal control activities in South African small, medium and micro enterprises
Authors: Bruwer Juan-Pierre , Coetzee Philna , Meiring Jacolize 
Published: July 2017

Background: Although South African small, medium and micro enterprises (SMMEs) play an imperative role in the stimulation of the national economy, previous research studies show that these business entities have severe sustainability problems as approximately 75% of them fail after being in operation for only 3 years. The latter dispensation is pinned on the belief that South African SMMEs make use of inadequate and ineffective internal control systems.Aim: Since a system of internal control comprises five inter-related elements, while also taking into consideration that management is ultimately responsible for the internal control in their respective business entities, which is greatly influenced by their managerial conduct, this research study placed focus on determining the relationship which exist between the managerial conduct and the internal control activities evident in South African SMMEs.Setting: This study was conducted in the Cape Metropole, South Africa by obtaining responses from 240 stakeholders of SMMEs: 120 members of management and 120 employees.Methods: In order to achieve the latter, quantitative data were collected through a questionnaire and analysed accordingly through both descriptive statistics and inferential statistics.Results: From the results, a very weak negative statistically significant relationship was identified between the managerial conduct and the internal control activities evident in South African SMMEs.Conclusion: Essentially, management and employees should revisit the internal control activities evident in their respective SMMEs through placing emphasis on those internal control activities which can be built on their control environment.
Successful Endoscopic Removal of 42 Magnetic Balls
Authors: Dole Michael , Hiremath Girish 
Published: July 2017

ABSTRACTForeign body ingestion in pediatric patients is a common emergency department presentation. Despite a ban and recall in 2014 for the magnetic toy “Buckyballs” due to posing a deadly risk if ingested, clinical cases continue to occur. The need for surgical management in the setting of multiple magnet ingestions is related to compromised blood supply when at least two magnets are attracted while separated by gastrointestinal mucosa, and previous studies have indicated that the majority of multiple magnet ingestions require surgical intervention. In the setting of a known recent ingestion, endoscopic removal can potentially safely avoid the morbidity and mortality associated with surgical procedures. We present an interesting clinical case of multiple magnetic ingestion managed with endoscopic procedure.
An Essential Extension of the Finite-Energy Condition for Extended Runge-Kutta-Nyström Integrators when Applied to Nonlinear Wave Equations
Authors: Mei Lijie , Liu Changying , Wu Xinyuan 
Published: July 2017

AbstractThis paper is devoted to an extension of the finite-energy condition for extended Runge-Kutta-Nyström (ERKN) integrators and applications to nonlinear wave equations. We begin with an error analysis for the integrators for multi-frequency highly oscillatory systems, whereMis positive semi-definite,. The highly oscillatory system is due to the semi-discretisation of conservative, or dissipative, nonlinear wave equations. The structure of such a matrixMand initial conditions are based on particular spatial discretisations. Similarly to the error analysis for Gaustchi-type methods of order two, where a finite-energy condition bounding amplitudes of high oscillations is satisfied by the solution, a finite-energy condition for the semi-discretisation of nonlinear wave equations is introduced and analysed. These ensure that the error bound of ERKN methods is independent of. Since stepsizes are not restricted by frequencies ofM, large stepsizes can be employed by our ERKN integrators of arbitrary high order. Numerical experiments provided in this paper have demonstrated that our results are truly promising, and consistent with our analysis and prediction.

Coordinación de competencias transversales en asignaturas de ámbito nuclear en el Grado de Ingeniero de la Energía
Authors: Gallardo Bermell Sergio , Carlos Sofía , Martorell Sebastián , Ródenas José 
Published: July 2017

Después de la implantación de los nuevos Grados y Másteres, la Universitat Politècnica de València (UPV) publicó una lista de competencias genéricas para agrupar los diferentes perfiles competenciales. Esta lista consta de un total de 13 competencias que deben trabajarse y evaluarse en las diferentes materias. En este marco, se debe mejorar la coordinación entre las asignaturas para asegurar que todas las competencias se trabajan a lo largo de la titulación. La coordinación debe considerar el diseño y la evaluación de las actividades. En las asignaturas de ámbito nuclear, se propone potenciar la relación entre asignaturas aprovechando las sinergias que exiten entre ellas. Una manera de conseguirlo es diseñando actividades que estén relacionadas con otras asignaturas, de forma que una misma competencia transversal pueda trabajarse en una asignatura pero estableciendo conexiones con otras. Partiendo de esta premisa, en este trabajo se presentan los beneficios de la coordinación en materia de competencias transversales y su repercusión en la integración de las asignaturas de ámbito nuclear. Palabras clave: competencia transversal, grado ingeniero de la energía, asignaturas de ámbito nuclear.
Una propuesta de mejora para el auto aprendizaje de la Competencia Comunicativa Oral en español: R/ele/CCO
Authors: Romero Forteza Francesca , Sáinz González María Del Mar 
Published: July 2017

Este trabajo se centra en la falta de recursos web centrados en el auto aprendizaje de la competencia comunicativa oral en español, que pensamos, podemos hacer extensible a otras lenguas. La competencia comunicativa oral es, según el MCERL, el fin en si mismo cuando aprendemos una lengua. Los recursos web están centrados en el aprendizaje de lenguas basados en ejercicios de prueba y error y repetición, dejando de lado el plano comunicativo de la lengua. Por ende, proponemos un recurso web para el auto aprendizaje de español como lengua extranjera centrado en el aprendizaje de rasgos conversacionales en español.

El presente trabajo muestra el desarrollo de un proyecto de innovación docente llevado a cabo con alumnos de dos grados, Estudios Hispánicos y Lenguas Modernas y Traducción, en la Universidad de Alcalá. El objetivo de estas páginas es exponer el desarrollo y resultados de este proyecto que surge de la visión de un aspecto fundamental: la vocación literaria de algunos alumnos de ambos grados. Partiendo de esta base, se propuso la realización de un poemario bilingüe en el que los alumnos del grado en Estudios Hispánicos crearan poemas que pudieran ser traducidos o, más bien, “re-creados”, por parte de los alumnos traductores. Los objetivos principales de este proyecto interdisciplinar son los de fomentar la creatividad y aumentar la motivación de los alumnos de ambos grados, así como reforzar el uso de la lengua extranjera y la práctica de la traducción literaria con textos originales creados por otros compañeros, fomentando así el trabajo colaborativo. Además, otro de los puntos innovadores de este proyecto es que los alumnos pudieran trabajar juntos a través de las nuevas tecnologías, utilizando, entre otras, la herramienta Blackboard Collaborate, que les permitiera estar en contacto, compartir documentos y opiniones en tiempo real.

Preface: The Oligotrophy to the UlTra-oligotrophy PACific Experiment (OUTPACE cruise, 18 February to 3 April 2015)

Abstract. The overall goal of OUTPACE (Oligotrophy to UlTra-oligotrophy PACific Experiment) was to obtain a successful representation of the interactions between planktonic organisms and the cycle of biogenic elements in the western tropical South Pacific Ocean across trophic and N2 fixation gradients. Within the context of climate change, it is necessary to better quantify the ability of the oligotrophic ocean to sequester carbon through biological processes. OUTPACE was organized around three main objectives, which were (1) to perform a zonal characterization of the biogeochemistry and biological diversity of the western tropical South Pacific during austral summer conditions, (2) to study the production and fate of organic matter (including carbon export) in three contrasting trophic regimes (increasing oligotrophy) with a particular emphasis on the role of dinitrogen fixation, and (3) to obtain a representation of the main biogeochemical fluxes and dynamics of the planktonic trophic network. The international OUTPACE cruise took place between 18 February and 3 April 2015 aboard the RV L'Atalante and involved 60 scientists (30 onboard). The west–east transect covered  ∼  4000 km from the western part of the Melanesian archipelago (New Caledonia) to the western boundary of the South Pacific gyre (French Polynesia). Following an adaptive strategy, the transect initially designed along the 19° S parallel was adapted along-route to incorporate information coming from satellite measurements of sea surface temperature, chlorophyll a concentration, currents, and diazotroph quantification. After providing a general context and describing previous work done in this area, this introductory paper elucidates the objectives of OUTPACE, the implementation plan of the cruise and water mass and climatological characteristics and concludes with a general overview of the other papers that will be published in this special issue.
