ABSTRACT
In the sixth of a series of papers reporting on a large reverberation mapping (RM) campaign of active galactic nuclei (AGNs) with high accretion rates, we present velocity-resolved time lags of Hβ emission lines for nine objects observed in the campaign during 2012–2013. In order to correct the line broadening caused by seeing and instruments before analyzing the velocity-resolved RM, we adopt the Richardson–Lucy deconvolution to reconstruct their Hβ profiles. The validity and effectiveness of the deconvolution are checked using Monte Carlo simulation. Five among the nine objects show clear dependence of the time delay on velocity. Mrk 335 and Mrk 486 show signatures of gas inflow whereas the clouds in the broad-line regions (BLRs) of Mrk 142 and MCG +06-26-012 tend to be radial outflowing. Mrk 1044 is consistent with having virialized motions. The lags of the remaining four are not velocity-resolvable. The velocity-resolved RM of super-Eddington accreting massive black holes (SEAMBHs) shows that they have diverse kinematics in their BLRs. Comparing with the AGNs with sub-Eddington accretion rates, we do not find significant differences in the BLR kinematics of SEAMBHs.

ABSTRACT
A historical problem for indirect exoplanet detection has been contending with the intrinsic variability of the host star. If the variability is periodic, it can easily mimic various exoplanet signatures, such as radial velocity (RV) variations that originate with the stellar surface rather than the presence of a planet. Here we present an update for the HD 99492 planetary system, using new RV and photometric measurements from the Transit Ephemeris Refinement and Monitoring Survey. Our extended time series and subsequent analyses of the Ca ii H&K emission lines show that the host star has an activity cycle of ∼13 years. The activity cycle correlates with the purported orbital period of the outer planet, the signature of which is thus likely due to the host star activity. We further include a revised Keplerian orbital solution for the remaining planet, along with a new transit ephemeris. Our transit-search observations were inconclusive.
ON THE ORIGIN OF THE SUB-JOVIAN DESERT IN THE ORBITAL-PERIOD–PLANETARY-MASS PLANE
Authors: Matsakos Titos , Königl Arieh 
Published: March 2016

ABSTRACT
Transit and radial velocity observations indicate a dearth of sub-Jupiter-mass planets on short-period orbits, outlined roughly by two oppositely sloped lines in the period–mass plane. We interpret this feature in terms of high-eccentricity migration of planets that arrive in the vicinity of the Roche limit, where their orbits are tidally circularized, long after the dispersal of their natal disk. We demonstrate that the two distinct segments of the boundary are a direct consequence of the different slopes of the empirical mass–radius relation for small and large planets, and show that this relation also fixes the mass coordinate of the intersection point. The period coordinate of this point, as well as the detailed shape of the lower boundary, can be reproduced with a plausible choice of a key parameter in the underlying migration model. The detailed shape of the upper boundary, on the other hand, is determined by the post-circularization tidal exchange of angular momentum with the star and can be reproduced with a stellar tidal quality factor

Effect of root-extracts of Ficus benghalensis (Banyan) in pain in animal models
Authors: Panday Dipesh Raj , Rauniar Gajendra Prasad 
Published: March 2016

ABSTRACT
Introduction: According to the WHO, 70–80% population in developing countries still relies on nonconventional medicine mainly of herbal origin. Even in developed countries, use of herbal medicine is growing each year. Pain is an unpleasant feeling often caused by intense or damaging stimuli. Traditionally, different plant parts of Ficus benghalensis are claimed to have several analgesic properties. Few scientific evidences support these uses. Interestingly, still others contradict these uses. It was shocking to find very scarce scientific studies trying to solve the mystery. Materials and Methods: It was a quantitative experimental study in Swiss albino mice of either sex. Sample size was calculated using free sample size calculating software G*Power version 3.1.9.2. Hot-plate test and tail-flick test were central antinociceptive paradigms. Writhing test was peripheral model for pain. Test drugs were aqueous root extracts of F. benghalensis at 100 mg/kg and 200 mg/kg mouse weight prepared by Soxhlet method. Suitable negative and positive controls were used. The experimental results were represented as mean ±standard deviation statistical level of significance was set at P < 0.05. For calculation, parametric test - one-way analysis of variance (ANOVA) or nonparametric test - Mann–Whitney U-test was appropriately used. Results: Hot-plate reaction time at 100 mg/kg (13.64 ±1.30 s) and 200 mg/kg (10.32 ±2.23 s) were nonsignificant (P = 0.425 and P = 0.498, respectively) compared to negative control (11.87 ±1.92 s). One-way ANOVA revealed nonsignificant (P = 0.178) between-group comparison in mean tail-flick reaction time. Test drug at 200 mg/kg produced statistically significant more writhing (36.00 ±14.85 in 10 min) than negative control, normal saline (11.83 ±12.43 in 10 min) or the positive control, Indomethacin (3.50 ±5.21 in 10 min), P value being 0.031 and 0.003, respectively. Conclusion: Aqueous root extracts of F. benghalensis at 200 mg/kg produces statistically significant writhing.

ABSTRACTSystemic lupus erythematosus (SLE) is an autoimmune disorder, primarily affect female in fertile age. Pregnancy in SLE female is a high-risk situation which can adversely affect maternal-fetal dyad. SLE can flare during pregnancy or in postpartum period. We describe a case of a young pregnant female who presented because of right hemiparesis due multiple hemorrhages in the brain. The first presentation of the SLE with multiple intracranial hemorrhages in pregnancy, preceding the other characteristic clinical symptoms is rare. Here, we high lighten the major neurological issues and maternal-fetal dyad issues in SLE pregnancy and treatment strategies for management of SLE in pregnancy.
A giant frontal cavernous malformation with review of literature
Authors: Sharma Arvind , Mittal Radhey Shyam 
Published: March 2016

ABSTRACTCavernous malformations (CMs) are vascular anomalies with dilated spaces called caverns. These spaces are lined by endothelial cells and collage and devoid of smooth muscle or intervening neural tissue, and filled with blood at various stages of stasis, thrombosis, organization, and calcification. Most CMs are relatively small in size but when they are large enough they can produce sing of mass effect and may simulate neoplastic, vascular, inflammatory pathology. Giant CM (size >6 cm) are very rare lesions and very few cases are reported in world literature. We are reporting such a rare case of a 16 year male. Our case is also unique in the sense that it is the largest reported CM in Indian population.
Feasibility of planned mini-laparotomy and adhesiolysis at the time of robotic-assisted radical prostatectomy in patients with prior major abdominal surgery

Published: March 2016

Introduction: Our aim was to report our experience on the feasibility of completing radical prostatectomy robotically after planned open adhesiolysis for prior major abdominal surgery with previous midline laparotomy scar.Methods: We searched our prospectively collected database of robotic assisted-radical prostatectomy (RARP) performed between October 2006 and October 2012 by a single fellowship-trained surgeon to identify all patients who underwent planned initial minilaparotomy for release of abdominal adhesions at time of RARP. Among 250 RARP patients, five patients fulfilled these criteria.Results: All patients had prostatectomy completed robotically. The mean values of patients’ demographics were as follows: Age 61.8 years (range 54‒69), body mass index 30.7 (range 24.3‒5.3), and prostate volume 41.5 ml (range 30.8‒54). Mean operative time was 245 min (range 190‒280) and estimated blood loss 410 ml (range 300‒650). Median hospital stay was one day (range 1‒7). Postoperatively, there was one prolonged ileus, which resolved spontaneously, and one myocardial infarction.Conclusions: Robotic completion of radical prostatectomy after open adhesiolysis is feasible. This approach maintains most minimally invasive advantages of RARP, despite a slightly longer hospital stay. In the best interest of patients, robotic surgeons are encouraged to finish the case robotically rather than attempting an open approach.
Exploration de la socialisation à l’écrit d’élèves créolophones scolarisés en français langue seconde
Authors: Fleuret Carole 
Published: March 2016

Cet article explore la socialisation à l’écrit de 11 élèves créolophones scolarisés en français langue seconde. Les résultats montrent que les élèves ont des connaissances du code alphabétique, mais qu’elles demeurent fragiles pour certains d’entre eux. Quant à la clarté cognitive du français écrit, une fluctuation plus grande apparaît dans les résultats. Les élèves ont une conscience de l’écrit, mais elle demande aussi à être renforcée. Pour soutenir la socialisation à l’écrit des élèves, nous pensons que la mise en place de programmes de littératie qui tiennent compte de l’habitus culturel de l’élève et de son environnement familial favoriserait le développement de leurs connaissances linguistiques en français langue seconde.
Les défis de l’intégration sociale et scolaire de jeunes d’origine haïtienne immigrés au Québec après le séisme survenu en Haïti en janvier 2010
Authors: Lafortune Gina 
Published: March 2016

Cet article présente les résultats d’une recherche qui a documenté le cheminement socioscolaire d’une quarantaine de jeunes d’origine haïtienne immigrés au Québec après le séisme survenu en Haïti en janvier 2010. Des entretiens individuels ont été réalisés avec les jeunes, quelques parents, des enseignants et des intervenants psychosociaux ou communautaires. Ils ont permis de retracer le vécu socioscolaire des jeunes avant et après l’immigration, les besoins qu’ils ont manifestés à l’arrivée au Québec et les formes de soutien reçues de leur environnement. Les résultats montrent la grande résilience des jeunes qui essaient de surmonter les deuils, les traumas et les séparations générés par le séisme en s’investissant dans leur cheminement scolaire. Plusieurs ont pu s’intégrer remarquablement à l’école québécoise. D’autres présentent un cumul de vulnérabilités. Cet article discute de ces résultats.
Rap, langues, « québéquicité » et rapports sociaux de sexe : pratiques et expériences de rappeuses montréalaises d’origine haïtienne
Authors: Lesacher Claire 
Published: March 2016

Depuis les récits retraçant ses premières heures, la scène rap montréalaise apparaît particulièrement investie par des acteurs d’origine haïtienne : un fait notamment palpable à travers les textes de rap, qui présentent fréquemment des occurrences en créole haïtien. Prenant acte de cette caractéristique du rap montréalais, nous proposons une réflexion sur les enjeux de la visibilité des migrants et descendants de migrants haïtiens au sein de l’espace public québécois, à travers une focalisation sur les pratiques et expériences de rappeuses montréalaises d’origine haïtienne. Dans cette contribution, qui vise à entrevoir les processus de majoration et de minoration à l’oeuvre dans le contexte montréalais et québécois, nous envisagerons notamment la manière dont les vecteurs de différenciation impliquant ce qui relève du linguistique, de la « québéquicité » ou des rapports sociaux de sexe s’actualisent et se reproduisent dans le cadre de la médiatisation des productions artistiques.

Published: March 2016

IntroductionLiver disease related to hepatitis B (HBV) and hepatitis C (HCV) may temper the success of antiretroviral therapy (ART) in China. Limited data exist on their prevalence in HIV‐positive Chinese. A multi‐centre, cross‐sectional study was carried out to determine the prevalence and disease characteristics of HBV and HCV co‐infection in HIV‐positive patients across 12 provinces.MethodsHIV‐positive ART‐naïve patients were recruited from two parent cohorts established during November 2008–January 2010 and August 2012–September 2014. Hepatitis B surface antigen (HBsAg), hepatitis B e antigen and HCV antibody (anti‐HCV) status were retrieved from parent databases at the visit prior to ART initiation. HBV DNA was then determined in HBsAg+ patients. HCV RNA was quantified in anti‐HCV+ patients. Aspartate aminotransferase‐to‐platelet ratio index (APRI) and the fibrosis‐4 (FIB4) were calculated. Chi‐square test, Kruskal–Wallis test and logistic regression were used for statistical analysis, as appropriate.ResultsOf 1944 HIV‐positive patients, 186 (9.5%) were HIV–HBV co‐infected and 161 (8.3%) were HIV–HCV co‐infected. The highest HIV–HBV prevalence (14.5%) was in Eastern China while the highest HIV–HCV prevalence was in the Central region (28.2%). HIV–HBV patients had lower median CD4 + T cell count (205 cells/μL) than either HIV monoinfected (242 cells/μL, P=0.01) or HIV–HCV patients (274 cells/μL, P=0.001). Moderate‐to‐significant liver disease was present in >65% of the HIV–HCV, ~35% of the HIV–HBV and ~20% of the HIV monoinfected patients. Independent associations with moderate‐to‐significant liver disease based on APRI included HBV (Odds ratio, OR 2.37, P < 0.001), HCV (OR 9.64, P<0.001), CD4 count≤200 cells/μL (OR 2.55, P<0.001) and age ≥30 years (OR 1.80, P=0.001).ConclusionsHBV and HCV prevalence is high in HIV‐positive Chinese and differs by geographic region. HBV and HCV co‐infection and HIV monoinfection are risks for moderate‐to‐significant liver disease. Only HIV–HBV is associated with greater HIV‐related immunosuppression. Incorporating screening and management of hepatitis virus infections into Chinese HIV programmes is needed.
Label-free detection of low-molecular-weight samples using a terahertz chemical microscope
Authors: Kuwana Takuya , Ogawa Masahiro , Sakai Kenji , Kiwa Toshihiko , Tsukada Keiji 
Published: March 2016

Abstract
A terahertz chemical microscope (TCM) has been proposed and developed to visualize the distribution of biomolecular interactions on a sensing plate without any labels. In this study, the concanavalin A (Con A)–d-(+)-mannose (mannose) interaction was detected using the TCM with mannose applied as the analyte and Con A immobilized on the sensing plate. To demonstrate this interaction, the amplitude of terahertz pulses as a function of Con A–mannose interaction time, as well as the Con A–mannose coupling concentration, was evaluated. The results suggest that coupling kinetics may be evaluated using a TCM.

Published: March 2016

Abstract
Transistors with low-power operation and sufficient signal processing speed have been widely required especially for mobile applications. To meet these requirements, we propose a novel tunneling- and diffusion-current hybrid MOSFETs which utilize both a small S-factor of tunneling-current and a high current drivability of diffusion-current. On the basis of the device concept and the working principle that we propose, device structures and parameters of the hybrid MOSFET were examined in detail with device simulation. We investigated the optimum structure of the tunneling and diffusion parts, and the effects of various structural parameters. In particular, we found that the threshold voltage adjustment of each current and the suppression of leakage current were the most important to maximize the characteristics of the hybrid MOSFET. From the result of structural parameter optimization, a minimum S-factor of 20 mV/decade and a high current drivability of 500 µA/µm were obtained simultaneously. In addition, a process flow idea to fabricate three-dimensional structure hybrid MOSFETs with tunneling-current side channels and diffusion-current top channel is presented.

Published: March 2016

Abstract
Field emitters with nanoscale tips and a fabrication technique using a nanoscale gap are described. Each fabrication technique makes it possible to form emitters on a meter-scale glass substrate. The emitter has a configuration with one side gate to reduce the electron scattering losses at the counter electrode to improve the emission efficiency. All thin film layers constituting the emitter are fabricated by plasma-enhanced chemical vapor deposition and sputtering deposition. Nanoscale tips are formed between a shallow gap less than 7 nm deep by the joule heating of a Mo complex oxide, which is produced by the electro chemical etching of a deposited Mo layer. To our knowledge, this is the first work that shows a uniform efficiency of 5% or more achieved at an anode voltage of 10 kV and an operation voltage of 23 V.
Analyzing charge distribution in the termination area of 4H-SiC diodes by measuring depletion-layer capacitance

Published: March 2016

Abstract
The distribution of positive-charge density at the SiO2/SiC interface of the termination area (Q
TM) was analyzed by measuring the depletion-layer capacitance of 4H-SiC PN diodes with different termination structures. A change in Q
TM induced by reverse-bias stressing (ΔQ
TM) caused a change in the breakdown voltage of the diodes. By comparing the measured depletion-layer capacitance to the simulated value, the initial Q
TM (

) and the distribution of ΔQ
TM were clarified. It is concluded from these results that the distribution of ΔQ
TM was not uniform but that positive charges mostly accumulated in the termination area under a high applied electric field.

Published: March 2016

Background.Obesity has reached epidemic proportions in dogs and, as in humans, cost of care has increased due to associated comorbidities. In humans, asymptomatic urinary tract infections (UTI) may be more prevalent in the obese. Asymptomatic bacteriuria (AB) is the term used when UTI are asymptomatic. We hypothesized that morbidly obese dogs are similarly more likely to have asymptomatic bacteriuria than lean, overweight, and moderately obese dogs.Methods.A retrospective study was undertaken to explore a possible association between obesity and asymptomatic bacteriuria. Records from lean, overweight, and obese dogs receiving both a dual energy absorptiometry (DXA) scan and urine culture were included.Results.Six positive urine cultures were identified among 46 dogs fulfilling search criteria. All six positive cultures were found in dogs with body fat percentage of >45%. In dogs with body fat percentage of <45%, there were no positive urine cultures.Discussion.There was an increased prevalence of asymptomatic bacteriuria in the morbidly obese dogs in this study compared to those that were lean, overweight, or moderately obese. Whether antibiotic therapy is necessary in such cases is still being debated, but because asymptomatic bacteriuria may be associated with ascending infections, uroliths, or other complications, the data reported herein support the screening of obese patients for bacteriuria.
Seismic shear waves as Foucault pendulum
Authors: Snieder Roel , Sens‐Schönfelder Christoph , Ruigrok Elmer , Shiomi Katsuhiko 
Published: March 2016

AbstractEarth's rotation causes splitting of normal modes. Wave fronts and rays are, however, not affected by Earth's rotation, as we show theoretically and with observations made with USArray. We derive that the Coriolis force causes a small transverse component for P waves and a small longitudinal component for S waves. More importantly, Earth's rotation leads to a slow rotation of the transverse polarization of S waves; during the propagation of S waves the particle motion behaves just like a Foucault pendulum. The polarization plane of shear waves counteracts Earth's rotation and rotates clockwise in the Northern Hemisphere. The rotation rate is independent of the wave frequency and is purely geometric, like the Berry phase. Using the polarization of ScS and ScS2 waves, we show that the Foucault‐like rotation of the S wave polarization can be observed. This can affect the determination of source mechanisms and the interpretation of observed SKS splitting.
Evaluation of landfalling atmospheric rivers along the U.S. West Coast in reanalysis data sets

Published: March 2016

AbstractAn intercomparison of landfalling atmospheric rivers (ARs) between four reanalysis data sets using one satellite‐derived AR detection method as a metric to characterize landfalling atmospheric rivers (ARs) along the U.S. West Coast is performed over 15 cool seasons (October–March) during the period from water years 1998 to 2012. The four reanalysis data sets analyzed in this study are the Climate System Forecast Reanalysis (CFSR), Modern‐Era Retrospective Analysis for Research and Applications (MERRA), ERA‐Interim (ERA‐I), and the Twentieth Century Reanalysis version 2 (20CR) data set. The Atmospheric River Detection Tool is used to identify AR features in the total vertically integrated water vapor (IWV) data of the reanalysis data, and validation of the reanalysis AR data are compared with AR data derived from satellite IWV observations. The AR landfall data from reanalysis were generally found to be in good agreement with satellite observations. Reanalysis data with less (CFSR) or no assimilation (20CR) of the satellite data used in this study had greater bias with AR characteristics such as IWV, width, and landfall location. The 20CR ensemble data were found to better characterize the AR landfall characteristics than the 20CR ensemble mean although all 20CR data underestimated AR landfalls particularly in the southern section of the U.S. West Coast. Overall AR landfall detections for the 15 year cool season period were within 5% of the satellite for the CFSR, MERRA, and ERA‐I data.
