Published: October 2017

Abstract
We present observations of distinct UV spectral properties at different locations during an atypical X-shaped flare (SOL2014-11-09T15:32) observed by the Interface Region Imaging Spectrograph (IRIS). In this flare, four chromospheric ribbons appear and converge at an X-point where a separator is anchored. Above the X-point, two sets of non-coplanar coronal loops approach laterally and reconnect at the separator. The IRIS slit was located close to the X-point, cutting across some of the flare ribbons and loops. Near the location of the separator, the Si iv 1402.77 Å line exhibits significantly broadened line wings extending to 200 km s−1 with an unshifted line core. These spectral features suggest the presence of bidirectional flows possibly related to the separator reconnection. While at the flare ribbons, the hot Fe xxi 1354.08 Å line shows blueshifts and the cool Si iv 1402.77 Å, C ii 1335.71 Å, and Mg ii 2803.52 Å lines show evident redshifts up to a velocity of 80 km s−1, which are consistent with the scenario of chromospheric evaporation/condensation.

Abstract
This work presents the photochemistry of ultraviolet (UV) irradiated coronene in water ices at 15 K studied using mid-infrared Fourier transform (FTIR) spectroscopy for C24H12:H2O at concentrations of (1:50), (1:150), (1:200), (1:300), and (1:400). Previous UV irradiation studies of anthracene:H2O, pyrene:H2O, and benzo[ghi]perylene:H2O ices at 15 K have shown that aromatic alcohols and ketones, as well as CO2 and H2CO, are formed at very low temperatures. Likewise, here, in addition to the coronene cation, hydroxy-, keto-, and protonated coronene (coronene H+) are formed. The rate constants for the decay of neutral coronene and for the formation of photoproducts have been derived. It is shown that Polycyclic Aromatic Hydrocarbons (PAHs) and their UV induced PAH:H2O photoproducts have mid-infrared spectroscopic signatures in the 5–8 μm region that can contribute to the interstellar ice components described by Boogert et al. as C1–C5. Our results suggest that oxygenated and hydrogenated PAHs could be in UV-irradiated regions of the interstellar medium where water-rich ices are important.
Multipoles and Force on External Points for a Two-layered Spheroidal Liquid Mass Rotating Differentialy

Published: October 2017

Abstract
We recently reported on a series of equilibrium figures for a self-gravitating heterogeneous liquid body, consisting of two concentric distorted spheroids, “nucleus” and “atmosphere,” each endowed with its own internal motion of differential rotation. In our current work, we calculate the body’s force at external points and obtain a multipolar expansion of the potential. We also give an account of figures with prolate nuclei, which remained unnoticed by us in our former paper.

Abstract
We present near-IR spectroscopy of 22 luminous low-ionization broad absorption line quasars (LoBAL QSOs) at redshift

, with 12 objects at z ∼ 1.5 and 10 at z ∼ 2.3. The spectra cover the rest-frame Hα and Hβ line regions, allowing us to obtain robust black hole mass estimates based on the broad Hα line. We use these data, augmented by a lower-redshift sample from the Sloan Digital Sky Survey, to test the proposed youth scenario for LoBALs, which suggests that LoBALs constitute an early short-lived evolutionary stage of quasar activity, by probing for any difference in their masses, Eddington ratios, or rest-frame optical spectroscopic properties compared to normal quasars. In addition, we construct the UV to mid-IR spectral energy distributions (SEDs) for the LoBAL sample and a matched non-BAL quasar sample. We do not find any statistically significant difference between LoBAL QSOs and non-BAL QSOs in their black hole mass or Eddington ratio distributions. The mean UV to mid-IR SED of the LoBAL QSOs is consistent with non-BAL QSOs, apart from their stronger reddening. At

there is no clear difference in their optical emission line properties. We do not see particularly weak [O iii] or strong Fe ii emission. The LoBAL QSOs do not show a stronger prevalence of ionized gas outflows as traced by the [O iii] line, compared to normal QSOs of similar luminosity. We conclude that the optical–MIR properties of LoBAL QSOs are consistent with the general quasar population and do not support them to constitute a special phase of active galactic nucleus evolution.
What Causes the High Apparent Speeds in Chromospheric and Transition Region Spicules on the Sun?
Authors: De Pontieu Bart , Martínez-Sykora Juan , Chintzoglou Georgios 
Published: October 2017

Abstract
Spicules are the most ubuiquitous type of jets in the solar atmosphere. The advent of high-resolution imaging and spectroscopy from the Interface Region Imaging Spectrograph (IRIS) and ground-based observatories has revealed the presence of very high apparent motions of order 100–300 km s−1 in spicules, as measured in the plane of the sky. However, line of sight measurements of such high speeds have been difficult to obtain, with values deduced from Doppler shifts in spectral lines typically of order 30–70 km s−1. In this work, we resolve this long-standing discrepancy using recent 2.5D radiative MHD simulations. This simulation has revealed a novel driving mechanism for spicules in which ambipolar diffusion resulting from ion-neutral interactions plays a key role. In our simulation, we often see that the upward propagation of magnetic waves and electrical currents from the low chromosphere into already existing spicules can lead to rapid heating when the currents are rapidly dissipated by ambipolar diffusion. The combination of rapid heating and the propagation of these currents at Alfvénic speeds in excess of 100 km s−1 leads to the very rapid apparent motions, and often wholesale appearance, of spicules at chromospheric and transition region temperatures. In our simulation, the observed fast apparent motions in such jets are actually a signature of a heating front, and much higher than the mass flows, which are of order 30–70 km s−1. Our results can explain the behavior of transition region “network jets” and the very high apparent speeds reported for some chromospheric spicules.
Se créer des doubles de soi
Authors: Guinard Frédérik 
Published: October 2017

Dans l’axe des recherches en clinique de la création, l’auteur propose d’envisager l’expérience cinématographique comme un mouvement auto-réfléxif de l’art humain qui prolonge les courants les plus réalistes de l’art pictural. A partir du récit de l’origine du cinématographe et de l’analyse de trois films : Dans la peau de John Malkovich, Le mystère Picasso et Fados , l’auteur explorera tout le jeu de paradoxalité qu’implique cette saisie de l’homme par lui-même au travers d’une expérience d’enregistrement scénarisée et de re-vision différée. Il montrera que le dispositif technique de l’art cinématographique constitue son propre angle mort et qu’il doit nécessairement se tourner vers d’autres arts pour évoluer d’un fantasme de saisie réaliste et holistique de l’identité humaine à une expérience auto-subjective empreinte de profondeur et de vérité.
Jeunesse populaire et État en Argentine
Authors: Martinez Candice 
Published: October 2017

En Argentine, la lutte contre la délinquance juvénile se constitue en objet de l’action publique avec l’arrivée au pouvoir du président Fernando de la Rúa, candidat de la coalition de partis appelée l’« Alliance », élu en 1999. Ce gouvernement centriste adopte un plan de prévention de la délinquance qui comprend un programme de prévention sociale ciblé sur les jeunes issus des quartiers dits marginaux, considérés en risque de devenir délinquants ou déjà engagés dans des activités illicites. Mais cette stratégie se heurte à la résistance des populations ciblées par cette politique publique, mettant au jour la difficile question du rapport entre l’État, les quartiers défavorisés et la jeunesse populaire. Cet article revient sur la place accordée à la jeunesse populaire dans l’action publique depuis le retour de la démocratie. Ensuite, à partir d’une enquête de terrain portant sur la mise en œuvre du programme « Communautés vulnérables » dans une villa miseria de la province de Buenos Aires, il réinterroge le rapport entre État, engagement politique et jeunesse populaire en Argentine à partir du point de vue des jeunes.
Introduction à une politique des frontières
Authors: Causse Jean-Daniel 
Published: October 2017

En introduction du dossier, Jean-Daniel Causse pose le problème de la frontière à l’articulation de la conjoncture et de la structure. En effet, si les questions de notre temps, liées à un contexte donné, sont particulières, il ne faut pas occulter ce qui fait de la frontière une élaboration propre au monde des humains. Trois éléments sont évoqués : d’abord, un exil, qui est certes celui que connaissent les hommes et les femmes qui par choix ou par nécessité émigrent, mais qui est également le fait que chacun habite d’emblée dans le lieu de l’Autre ; ensuite, la positivité de l’idée de frontière contre les fantasmes d’un monde sans limite et en même temps le drame d’une frontière qui sert à construire des identités par différenciation avec une tendance à persécuter ce qui n’est pas soi ; enfin, la notion de frontière interprétée en fonction d’un franchissement qui donne une certaine valeur éthique à l’idée même de transgression.
Effect of Vitamin D therapy on urinary albumin excretion, renal functions, and plasma renin among patients with diabetic nephropathy
Authors: Liyanage PLGC , Lekamwasam S , Weerarathna TP , Liyanage C 
Published: October 2017

Background:
Despite different management strategies, progression of proteinuria occurs in a sizable category of patients with diabetic nephropathy (DN). Increase in serum renin levels induced by the renin–angiotensin system (RAS) may contribute to this. Vitamin D therapy is found to have an inhibitory effect on the RAS. We aimed to study the effects of Vitamin D therapy on renal functions of patients with DN.

Methods:
This was a double-blind, randomized, placebo-controlled study. Patients with DN (urinary albumin [UA] >30 mg/g of creatinine) whose estimated glomerular filtration rate (eGFR) was more than 30 mL/min were selected and their plasma renin, parathyroid hormone, serum Vitamin D, serum calcium, serum creatinine, fasting blood sugar were done as baseline measurements. Subjects were randomized into two groups and treatment group was given Vitamin D, 50000 IU (0.25 ml) intramuscularly (IM) monthly for 6 months; control group received distilled water IM. Investigations were repeated after 6 months of therapy.

Results:
Of 155 patients invited, 85 were randomly assigned to two groups. After 6 months, mean reduction of UA to creatinine ratio in the treatment and control group was 51.8 mg/g (95% confidence interval [CI]; 66.1–−37.5, P ≤ 0.001); 22.4 mg/g (95% CI; −45.7–0.8, P = 0.06), respectively (between group difference P = 0.001). Significant increase in the eGFR observed in the treatment group while eGFR remained unchanged in the control group (P = 0.03 for the between-group difference). Mean reduction in plasma renin in treatment group and control group was 5.85 pg/mL (95% CI; −6.7–−4.6) (P < 0.001) and 0.95 pg/mL (95% CI; −1.4–−0.14, P = 0.02), respectively.

Conclusions:
Vitamin D 50000 IU given IM monthly for 6 months reduces urine albumin, serum creatinine, and renin levels in patients with DN.
Comparison of stress and burnout among anesthesia and surgical residents in a tertiary care teaching hospital in North India
Authors: Gandhi K , Sahni N , Padhy SK , Mathew PJ 
Published: October 2017

Objective:
The residents undergoing training at hospitals in our country face challenges in terms of infrastructure and high workload with undefined working hours. The aim of the study was to compare the stress and burnout levels in trainee doctors doing residency in surgical fields and anesthesia at a tertiary care academic center in North India.

Materials and Methods:
A comparative, observational study was conducted in a tertiary care teaching hospital in North India. After Ethics Committee approval, 200 residents (100 each from surgical branches and anesthesia) were required to fill a questionnaire with information about age, sex, year of residency, marital status, and the Perceived Stress Scale-10, and Burnout Clinical Subtype Questionnaire-12. Burnout and perceived stress were compared between residents of anesthesia and surgical specialties.

Results:
Residents of both surgical and anesthesia branches scored high in perceived stress, namely 21 and 18, respectively. The score was significantly higher in surgical residents (P = 0.03) and increased progressively with the year of residency. The majority of residents (90% surgical, 80% anesthesia) felt that they were being overloaded with work. However, only 20%–30% of respondents felt that there was lack of development of individual skills and still fewer (<10%) reported giving up in view of difficulties.

Conclusion:
There is high level of stress and overload dimension of burnout among the residents of anesthesia and surgical branches at our tertiary care academic institution and the surgical residents score marginally higher than anesthesia residents.
Earthquake response of heavily damaged historical masonry mosques after restoration
Authors: Altunışık Ahmet Can , Genç Ali Fuat 
Published: October 2017

Abstract. Restoration works have been accelerated substantially in Turkey in the last decade. Many historical buildings, mosques, minaret, bridges, towers and structures have been restored. With these restorations an important issue arises, namely how restoration work affects the structure. For this reason, we aimed to investigate the restoration effect on the earthquake response of a historical masonry mosque considering the openings on the masonry dome. For this purpose, we used the Hüsrev Pasha Mosque, which is located in the Ortakapı district in the old city of Van, Turkey. The region of Van is in an active seismic zone; therefore, earthquake analyses were performed in this study. Firstly a finite element model of the mosque was constructed considering the restoration drawings and 16 window openings on the dome. Then model was constructed with eight window openings. Structural analyses were performed under dead load and earthquake load, and the mode superposition method was used in analyses. Maximum displacements, maximum–minimum principal stresses and shear stresses are given with contours diagrams. The results are analyzed according to Turkish Earthquake Code (TEC, 2007) and compared between 8 and 16 window openings cases. The results show that reduction of the window openings affected the structural behavior of the mosque positively.
Jewish Humor and Woody Allen's Short Fiction
Authors: Precup Amelia 
Published: October 2017

ABSTRACT
Woody Allen's short fiction has received much less scholarly attention than his films. Scholars who have investigated the humorous qualities of Allen's short stories and casual pieces have noted his penchant for absurdity and non sequitur, his use of the Little Man as a vehicle for humor, and the linguistic dimensions of his joke scripts rather than his Jewish comic sensibilities. Beginning with a brief overview on how Jewish humor has contributed to the comic achievements of American culture and drawing on analyses of the main characteristics of Jewish humor, this article adds to the scholarship by exploring the influence of Jewish humorous traditions on Woody Allen's short fiction.

Abstract
The Thermo Scientific RapidFinder™ Salmonella Species, Typhimurium, and Enteritidis Multiplex PCR Kit (candidate method) is a real-time PCR assay for the detection and differentiation of Salmonella spp., and the serovars S. Typhimurium, and S. Enteritidis from poultry, pork, and environmental samples. The method was validated in comparison to the U.S. Department of Agriculture Food Safety and Inspection Service and the U.S. Food and Drug Administration reference methods. Thermo Fisher Scientific (Basingstoke, United Kingdom) tested all matrixes. In addition, two matrixes were analyzed independently by Q Laboratories, Inc. (Cincinnati, OH). Few statistically significant differences were found between the candidate and reference methods when analyzed by probability of detection. When differences were observed, these were in favor of the candidate method. All 200 inclusivity strains and none of the 45 exclusivity strains were detected, which demonstrated that the RapidFinder Salmonella Species, Typhimurium, and Enteritidis Multiplex PCR Kit was able to detect all the major groups of Salmonella, the less common subspecies of S. enterica, and the rarely encountered S. bongori. None of the exclusivity isolates analyzed were detected. Robustness testing demonstrated that the assay gave reliable performance, with specific method deviations outside the recommended parameters. Accelerated stability testing was conducted, validating the assay shelf life.
Two Sources of Nonisotropic Radiation From Underground Explosions in Granite
Authors: Vorobiev O. Yu. 
Published: October 2017

AbstractSignificant tangential ground motion observed during underground explosions makes it difficult to distinguish them from natural earthquakes. Such motion can be generated by the source geometry and emplacement conditions, by the heterogeneous nature of the rock mass (mechanical properties may vary in space due to the presence of cracks, joints, faults, and various geologic layers) and also by the nonuniform in situ stress state. The last mechanism is increasingly important with depth when the difference in main principal stresses becomes significant. This paper is focused on the role of material strength of the rock mass in generation of nonradial motion during explosions in prestressed media. Numerical modeling of underground chemical explosions in granite at various depths has been conducted to compare two possible mechanisms of shear wave generation. The first, caused by rock mass anisotropy, is important at shallow depth. The second is related to elastic‐plastic relaxation around the cavity created by the explosion. Tangential motions for these two mechanisms have different signatures.
Separation of O/X Polarization Modes on Oblique Ionospheric Soundings

Published: October 2017

AbstractThe oblique‐incidence sounder (OIS) is a well‐established instrument for determining the state of the ionosphere, with several advantages over vertical‐incidence sounders (VIS). However, the processing and interpretation of OIS ionograms is more complicated than that of VIS ionograms. Due to the Earth's magnetic field, the ionosphere is birefringent at radio frequencies and a VIS or OIS will typically see two distinct ionospheric returns, known as the O and X modes. The separation of these two modes on a VIS, using a polarimetric receive antenna, is a well‐established technique. However, this process is more complicated on an OIS due to a variable separation in the phase difference between the two modes, as measured between the two arms of a polarimetric antenna. Using a polarimetric antenna that can be rotated and tilted, we show that this variation in phase separation within an ionogram is caused by the variation in incidence angle, with some configurations leading to greater variation in phase separation. We then develop an algorithm for separating O and X modes in oblique ionograms that can account for the variation in phase separation, and we demonstrate successful separation even in relatively difficult cases. The variation in phase separation can also be exploited to estimate the incident elevation, a technique which may be useful for other applications of HF radio.

AbstractAlumosilicate materials of different morphologies, such as platy and tubule nanoclays, may serve as an efficient, protective encasing for colored organic substances and nanoparticles. The adsorption of dyes onto the nanoclays increases their stability against thermal, oxidative, and acid–base‐induced decomposition. Natural organic dyes form stable composites with clays, thus allowing for “green” technology in production of industrial nanopigments. In the presence of high‐surface‐area alumosilicate materials, semiconductor nanoparticles known as quantum dots are stabilized against agglomeration during their colloid synthesis, resulting in safe colors. The highly dispersed nanoclays such as tubule halloysite can be employed as biocompatible carriers of quantum dots for the dual labeling of living human cells—both for dark‐field and fluorescence imaging. Therefore, complexation of dyes with nanoclays allows for new, stable, and inexpensive color formulations.
In Situ Carbon Homogeneous Doping on Ultrathin Bismuth Molybdate: A Dual‐Purpose Strategy for Efficient Molecular Oxygen Activation

Published: October 2017

AbstractSolar‐driven activation of molecular oxygen, which harnesses light to produce reactive oxygen species for the removal of pollutants, is the most green and low‐cost approach for environmental remediation. The energy coupling between photons, excitons, and oxygen is the crucial step in this reaction and still remains a challenge. In this study, a dual‐purpose strategy for enhanced molecular oxygen activation is established by in situ carbon homogeneous doping on ultrathin Bi2MoO6 nanosheets for the first time. The C‐doped ultrathin 2D material exhibits an enlarged bandgap straddling the electrochemical potential of O2 /•O2− and H2O /•OH, without any attenuation of light absorption. An internal electric field and shortened carrier‐transportation distance are also found in the longitude orientation of the nanosheets ([001] axis), leading to a higher density of effective photogenerated carriers localized on the exposed {001} surface. As applied for the nitric oxide removal, the reactive rate over the ultrathin C‐doped Bi2MoO6 nanosheets is 4.3 times higher than that over the bulk counterparts as a result of the increasing reactive oxygen species. This new proof‐of‐concept strategy not only realizes the band structure engineering and charge transportation regulation but also paves a new way to construct highly efficient photocatalytic materials.
