NUMERICAL SIMULATIONS OF KELVIN–HELMHOLTZ INSTABILITY: A TWO-DIMENSIONAL PARAMETRIC STUDY
Authors: Tian (田春林) Chunlin , Chen (陈耀) Yao 
Published: June 2016

ABSTRACT
Using two-dimensional simulations, we numerically explore the dependences of Kelvin–Helmholtz (KH) instability upon various physical parameters, including viscosity, the width of the sheared layer, flow speed, and magnetic field strength. In most cases, a multi-vortex phase exists between the initial growth phase and the final single-vortex phase. The parametric study shows that the evolutionary properties, such as phase duration and vortex dynamics, are generally sensitive to these parameters, except in certain regimes. An interesting result is that for supersonic flows, the phase durations and saturation of velocity growth approach constant values asymptotically as the sonic Mach number increases. We confirm that the linear coupling between magnetic field and KH modes is negligible if the magnetic field is weak enough. The morphological behavior suggests that the multi-vortex coalescence might be driven by the underlying wave–wave interaction. Based on these results, we present a preliminary discussion of several events observed in the solar corona. The numerical models need to be further improved to perform a practical diagnostic of the coronal plasma properties.
ON THE HOST GALAXY OF GRB 150101B AND THE ASSOCIATED ACTIVE GALACTIC NUCLEUS

Published: June 2016

ABSTRACT
We present a multi-wavelength analysis of the host galaxy of short-duration gamma-ray burst (GRB) 150101B. Follow-up optical and X-ray observations suggested that the host galaxy, 2MASX J12320498-1056010, likely harbors low-luminosity active galactic nuclei (AGNs). Our modeling of the spectral energy distribution has confirmed the nature of the AGN, making it the first reported GRB host that contains an AGN. We have also found the host galaxy is a massive elliptical galaxy with stellar population of ∼5.7 Gyr, one of the oldest among the short-duration GRB hosts. Our analysis suggests that the host galaxy can be classified as an X-ray bright, optically normal galaxy, and the central AGN is likely dominated by a radiatively inefficient accretion flow. Our work explores an interesting connection that may exist between GRB and AGN activities of the host galaxy, which can help in understanding the host environment of the GRB events and the roles of AGN feedback.
HOW ELSE CAN WE DETECT FAST RADIO BURSTS?
Authors: Lyutikov Maxim , Lorimer Duncan R. 
Published: June 2016

ABSTRACT
We discuss possible electromagnetic signals accompanying Fast Radio Bursts (FRBs) that are expected in the scenario where FRBs originate in neutron star magnetospheres. For models involving Crab-like giant pulses, no appreciable contemporaneous emission is expected at other wavelengths. However, magnetar giant flares, driven by the reconfiguration of the magnetosphere, can produce both contemporaneous bursts at other wavelengths as well as afterglow-like emission. We conclude that the best chances are: (i) prompt short GRB-like emission, (ii) a contemporaneous optical flash that can reach naked eye peak luminosity (but only for a few milliseconds), and (iii) a high-energy afterglow emission. Case (i) could be tested by coordinated radio and high-energy experiments. Case (ii) could be seen in a coordinated radio-optical surveys, e.g., by the Palomar Transient Factory in a 60 s frame as a transient object of m = 15–20 mag with an expected optical detection rate of about 0.1 hr−1, an order of magnitude higher than in radio. Shallow, but large-area sky surveys such as ASAS-SN and EVRYSCOPE could also detect prompt optical flashes from the more powerful Lorimer-burst clones. The best constraints on the optical to radio power for this kind of emission could be provided by future observations with facilities like Large Synoptic Survey Telescope. Case (iii) might be seen in relatively rare cases that the relativistically ejected magnetic blob is moving along the line of sight.
DETECTION OF PHOSPHORUS, SULPHUR, AND ZINC IN THE CARBON-ENHANCED METAL-POOR STAR BD+44 493*

Published: June 2016

ABSTRACT
The carbon-enhanced metal-poor star BD+44°493 ([Fe/H] = −3.9) has been proposed as a candidate second-generation star enriched by metals from a single Pop III star. We report the first detections of P and S and the second detection of Zn in any extremely metal-poor carbon-enhanced star, using new spectra of BD+44°493 collected by the Cosmic Origins Spectrograph on the Hubble Space Telescope. We derive [P/Fe] = −0.34 ± 0.21, [S/Fe] = +0.07 ± 0.41, and [Zn/Fe] = −0.10 ± 0.24. We increase by 10-fold the number of Si i lines detected in BD+44°493, yielding [Si/Fe] = +0.15 ± 0.22. The [S/Fe] and [Zn/Fe] ratios exclude the hypothesis that the abundance pattern in BD+44°493 results from depletion of refractory elements onto dust grains. Comparison with zero-metallicity supernova (SN) models suggests that the stellar progenitor that enriched BD+44°493 was massive and ejected much less than 0.07 M
⊙ of 56Ni, characteristic of a faint SN.

Calculating ultra-low-frequency wave power of the compressional magnetic field vs. &lt;i&gt;L&lt;/i&gt; and time: multi-spacecraft analysis using the Van Allen probes, THEMIS and GOES
Authors: Sarris Theodore E. , Li Xinlin 
Published: June 2016

Abstract. Ultra-low-frequency (ULF) pulsations are critical in radial diffusion processes of energetic particles, and the power spectral density (PSD) of these fluctuations is an integral part of the radial diffusion coefficients and of assimilative models of the radiation belts. Using simultaneous measurements from two Geostationary Operational Environmental Satellites (GOES) geosynchronous satellites, three satellites of the Time History of Events and Macroscale Interactions during Substorms (THEMIS) spacecraft constellation and the two Van Allen probes during a 10-day period of intense geomagnetic activity and ULF pulsations of October 2012, we calculate the PSDs of ULF pulsations at different L shells. By following the time history of measurements at different L it is shown that, during this time, ULF wave power is not enhanced uniformly throughout the magnetosphere but instead is mostly enhanced in the outer L shells, close to the magnetopause, and to a lesser extent in the inner magnetosphere, closer to the plasmapause. Furthermore, by using phase differences between two GOES geosynchronous satellite pairs, we estimate the daily-averaged distribution of power at different azimuthal wave numbers. These results can have significant implications in better defining the effect of radial diffusion in the phase space density of energetic particles for different wave numbers or L shell distributions of ULF power.

Published: June 2016

Purpose The prognostic impact of baseline C-reactive protein (CRP) in non-small-cell lung cancer (NSCLC) is debated. To evaluate this issue, we performed a systematic review and meta-analysis to explore the role of CRP value in predicting early-stage NSCLC survival. Methods Ten articles on early-stage NSCLC were eligible and included in our study. We performed a random-effects meta-analysis and assessed heterogeneity and publication bias. We pooled hazard ratio (HR) estimates and their 95% confidence intervals (CIs) on mortality for the comparison between the study-specific highest category of CRP level versus the lowest one. Results In overall analysis, elevated pretreatment CRP values were significantly associated with poor overall survival (HR 1.60, 95% CI 1.30-1.97, p<0.001, I2 = 71.9%). Similar results were observed across considered strata. However, higher mortality risk was reported in studies in which CRP was combined with other factors (HR 1.96, 95% CI 1.58-2.45) and in those using a cutoff value of 3 mg/L (HR 1.89, 95% CI 1.52-2.35). Conclusions Based on our analysis, baseline high CRP level is significantly associated with poor prognosis in early-stage NSCLC. Further prospective controlled studies are needed to confirm these data.

Two adjacent individual fibroepithelioma of Pinkus of the umbilicus—one pink, one pigmented—a case report and review of the literature
Authors: Inskip Mike , Longo Caterina , Haddad Afaf 
Published: June 2016

We present a unique case of separate and independent adjacent fibroepitheliomas of Pinkus (FeP) arising from the umbilicus in an 83-year-old man. Of further interest, one is pigmented and the other nonpigmented. Clinical, dermatoscopic and histopathological images are provided.
A review of the published literature is undertaken to attempt to assess the incidence of pigmented versus nonpigmented FeP. Of 24 published FeP cases, 10 (41.7%) have been pigmented. Thus to date pigmented FeP comprise approaching one-half of all reported cases.
Diet and acne: an exploratory survey study of patient beliefs
Authors: Nguyen Quynh-Giao , Markus Ramsey , Katta Rajani 
Published: June 2016

Background: In the past, medical literature reflected that diet was not a proven cause of acne. However, studies in recent years have substantiated a link between certain dietary factors and acne. It is unclear whether patients are aware of recent research findings.
Objectives: Acne patients were surveyed to explore beliefs regarding the link between diet and acne, to determine whether these beliefs translated into behavior change and to identify health information sources.
Patients/Methods: Upon Institutional Review Board (IRB) approval, surveys were administered to 50 acne patients at an academic dermatology clinic in 2014, with 49 completed in full and included in this analysis.
Results: Ninety-two percent of respondents believed that diet could affect acne. Seventy-one percent attempted to change their diet to improve acne. Seventy-one percent believed acne to be caused by fried or greasy foods, although chocolate (53%), dairy (47%), and soda drinks (35%) were highly implicated. Patients obtained information from Google searches (49%), dermatologists (43%), family members and TV (41% each), and medical websites (31%).
Conclusions: In this exploratory study, patients reported utilizing a diversity of information sources, a majority from the Internet. In those surveyed, there was a persistence of long-held belief that fried/greasy foods and chocolate may serve as acne triggers, and less belief in trigger foods supported by recent research, including refined carbohydrates and sugar. Given the multiplicity of beliefs and utilized sources among acne patients in our survey, there is a need to establish up-to-date and reliable methods to educate patients on diet and acne.
Spitz/Reed nevi: a review of clinical-dermatoscopic and histological correlation
Authors: Pedrosa Ana F. , Lopes Jose M. , Azevedo Filomena , Mota Alberto 
Published: June 2016

Background: Spitz/Reed nevi are melanocytic lesions that may mimic melanoma at clinical, dermatoscopic and histopathological levels. Management strategies of these lesions remain controversial.
Objectives: We aim a correlation among clinical-dermatoscopic and histological features of a series of Spitz/Reed nevi diagnosed during 7 years at the Department of Dermatology.
Methods: Clinical, dermatoscopic and histological features of Spitz/Reed nevi diagnosed at our tertiary hospital from 2008 to 2014 were reviewed in order to seek correlation.
Results: All described dermatoscopic patterns for Spitz/Reed nevi were found among the 47 enrolled patients; starburst and atypical/multicomponent patterns prevailed (57.4%). Reticular pattern predominated among children younger than 12 years, whereas homogeneous pattern was more frequent in patients older than 12 years, although these differences were not statistically significant (P=0.785). Among histological atypical lesions, all dermatoscopic patterns were represented, but the atypical/multicomponent predominated (56.3%). Two out of 11 dermatoscopically atypical lesions did not show histopathological counterpart.
Conclusions: The excision of Spitz/Reed nevi in adults is supported, given the inability to accurately predict those with histopathological atypia, based on clinical and dermatoscopic features, which may raise concern about malignancy.

The health and social costs of chronic kidney disease in Italy
Authors: Cicchetti Americo , Ruggeri Matteo , Codella Paola , Ridolfi Alessandro 
Published: June 2016

Chronic kidney disease is growing as a global public health problem throughout the world. In Italy, CKD is becoming increasingly common with 52,777 patients treated with dialysis in 2010, about 10,000 new patients/years in dialysis from 2010. The impact on the health care system includes € 2.1 billion/year for dialysis plus € 338 million for indirect costs. Aim of the present analysis was to explore socio-economical variables in the management of CKD, and assess direct and indirect health costs and NHS resources consumption. The overall cost for patients in dialysis is about 44,000 €/years for hemodialysis and 30,000 €/years for peritoneal dialysis with different resources consumption over the different stage disease. The possibility of reducing the progression of renal damaging and beginning of dialysis may induce a low expenditure for the Italian NHS.
Le théâtre immersif est-il interactif ? L’engagement du spectateur entre immersion et interactivité
Authors: Bouko Catherine 
Published: June 2016

Le concept d’immersion théâtrale rencontre aujourd’hui un succès grandissant, tant auprès des artistes que des chercheurs. Combiner les notions d’immersion et d’interactivité semble aller de soi lorsque l’on évoque le théâtre immersif, pour certains artistes, théoriciens ou journalistes, pour qui le spectateur est invité à habiter l’espace du spectacle. Est-il pourtant si naturel de combiner ces deux notions ? Comment combiner le développement d’une histoire, fut-elle non linéaire, et une organisation interactive ? Dans cet article, Catherine Bouko propose de traiter les rapports entre théâtre immersif et interactivité en trois points. Dans un premier temps, elle définit la notion d’interactivité, afin d’insister sur ce qu’elle est… et sur ce qu’elle n’est pas. Ensuite, elle présente rapidement une définition du théâtre immersif. Dans un troisième temps, elle aborde trois techniques dramaturgiques visant essentiellement une personnalisation des spectacles immersifs, sans pour autant toujours atteindre l’interactivité et une véritable intégration dans une image habitable.
La politique du citoyen (sur un passage orphelin du Contrat social)
Authors: Bernardi Bruno 
Published: June 2016

L’analyse d’un passage peu commenté du Contrat social (III, IX) montre que Rousseau aborde d’une façon singulière la problématique aussi classique qu’actuelle des rapports entre liberté et sécurité. La position de sujet (membre de l’État) et celle de citoyen (membre du peuple souverain) découlent toutes deux de la nature du corps politique. Elles sont porteuses de deux types d’exigences : la protection des personnes et des biens dans un cas, celle de la liberté civile et politique dans l’autre. Rousseau n’oppose pas ces exigences entre elles mais distingue les deux ordres de priorité qu’elles rendent possibles. La politique du citoyen consiste à faire de la liberté la condition de la sécurité.
Les propriétés du vide et de l’espace-temps
Authors: Le Bihan Baptiste 
Published: June 2016

Les propriétés matérielles sont généralement appréhendées comme les propriétés d’une substance matérielle : cette chemise possède la propriété d’être bleue, cette chaussure la propriété d’être en bon état. Pourtant, on peut trouver plusieurs raisons de douter que les propriétés soient nécessairement les propriétés d’une substance matérielle, à la fois en métaphysique avec la théorie du faisceau, et en physique contemporaine à travers les notions d’énergie du vide et de champ. Or, si les propriétés ne sont pas les propriétés de substances matérielles, on peut s’interroger sur la théorie de l’instanciation qu’implique une telle thèse. Dans cet essai, je m’emploierai à examiner la cohérence et la plausibilité de la thèse selon laquelle certaines, voir toutes les propriétés matérielles ne sont pas instanciées par une substance et la théorie de l’instanciation qui en découle.
Reconnaissance et justice éducative

Published: June 2016

Si les théories de la reconnaissance ont permis de renouveler plusieurs domaines de l’éthique, peu d’auteurs se sont intéressés jusqu’à présent à leur apport aux débats éducatifs. Or, que peut précisément le concept de reconnaissance pour l’éthique de l’éducation ? C’est la question posée par cet article. Examinant de prime abord plusieurs propositions faites par la littérature, cette étude leur oppose ensuite une vision plus exigeante de la reconnaissance, soit, le fondement légitime d’une théorie relationnelle de la justice éducative.
Loss reduction of leaky surface acoustic wave by loading with high-velocity thin film
Authors: Kakio Shoji , Hosaka Keiko 
Published: June 2016

Abstract
The propagation properties of a leaky surface acoustic wave (LSAW) on rotated Y-cut X-propagating lithium niobate (YX-LN) substrates loaded with an aluminum nitride (AlN) thin film with a higher phase velocity than that of the substrate were investigated theoretically and experimentally. From the theoretical calculation, it was found that the minimum attenuation can be obtained at a certain thickness of the AlN thin film for a cut angle ranging from 0 to 60° because the cut angle giving the minimum attenuation shifts toward a smaller cut angle as the film thickness is increased. The propagation properties of an LSAW on several rotated YX-LN substrates were measured by using an interdigital transducer (IDT) pair with a wavelength λ of 8 µm, and the predicted shifts of the minimum attenuation toward a smaller cut angle were demonstrated experimentally. For 0° and 10°YX-LN samples, the measured insertion loss and propagation loss were markedly reduced by loading with the AlN thin film. A larger electromechanical coupling factor (16.9%) than that at the cut angle giving zero attenuation without a film and a propagation loss less of 0.02 dB/λ were obtained simultaneously at a film thickness of 0.125 λ for the 10°YX-LN sample.
Induction thermal plasma synthesis of lithium oxide composite nanoparticles with a spinel structure

Published: June 2016

Abstract
Li–Mn composite oxide nanoparticles are synthesized using an induction thermal plasma, and the formation mechanism is investigated on the basis of the homogenous nucleation rate and thermodynamic considerations. Under a high O2 partial pressure, MnO crystals nucleate and Li oxide condenses on MnO nuclei at a relatively high rate, forming LiMn2O4 in a single phase. On the other hand, under a low partial pressure of O2, LiMnO2 is obtained owing to the low condensation rate of Li oxide. This study presents the successful selective synthesis of LiMn2O4 nanoparticles by controlling the partial pressure of O2.
Response of the hyporheic zone to transient groundwater fluctuations on the annual and storm event time scales
Authors: Malzone Jonathan M. , Lowry Christopher S. , Ward Adam S. 
Published: June 2016

AbstractThe volume of the water stored in and exchanged with the hyporheic zone is an important factor in stream metabolism and biogeochemical cycling. Previous studies have identified groundwater direction and magnitude as one key control on the volume of the hyporheic zone, suggesting that fluctuation in the riparian water table could induce large changes under certain seasonal conditions. In this study, we analyze the transient drivers that control the volume of the hyporheic zone by coupling the Brinkman‐Darcy equation to the Navier‐Stokes equations to simulate annual and storm induced groundwater fluctuations. The expansion and contraction of the hyporheic zone was quantified based on temporally dynamic scenarios simulating annual groundwater fluctuations in a humid temperate climate. The amplitude of the groundwater signal was varied between scenarios to represent a range of annual hydrologic forcing. Storm scenarios were then superimposed on the annual scenario to simulate the response to short‐term storm signals. Simulations used two different groundwater storm responses; one in‐phase with the surface water response and one 14 h out‐of‐phase with the surface water response to represent our observed site conditions. Results show that annual groundwater fluctuation is a dominant control on the volume of the hyporheic zone, where increasing groundwater fluctuation increases the amount of annual variation. Storm responses depended on the antecedent conditions determined by annual scenarios, where the time of year dictated the duration and magnitude of the storm induced response of the hyporheic zone.
