Published: September 2017

Abstract
Background: Imposter syndrome (IS) first described in 1978 is recently gaining more importance due to its long lasting, strong and detrimental implications on the Medical students as well as the institutions and society. The sufferers are competent objectively but they have a secret fear in them, that they are inadequate in the skills and knowledge and this secret will be open to others anytime. It is strongly associated with burnout phenomenon, anxiety, depression, many other psychological effects and many significant implications on medical education and training. Suffering students develop different styles of learning and find it difficult to learn through conventional or usual teaching strategies.
Objectives: This study objective was to find out the frequency of IS among Pakistani medical students.
Methodology: This was a cross sectional, descriptive study, conducted in a private medical college of Lahore, Pakistan in November 2016. Sampling technique was convenient non-probability type and study instrument was 08 items questionnaire. The students who answered “Yes” for five or more out of eight questions were considered positive for Imposter Syndrome.
Results: Out of 143 final year MBBS students 58.7% were females & 41.3% males. Sixty eight (68) students (47.5%) were found having Imposter Syndrome according to the Young Imposter scale (YIS) used as questionnaire. Out of these 45 (53.5%) were females and 23 (38.9%) males.
Conclusion: Imposter syndrome or phenomenon may be present in significant frequencies and number among medical students. This may have detrimental effects on body, mind, personalities and academic as well as professional developments. Efforts should be made to find out IS/IP among students and to train both students and teachers.
Quantifying the contribution of flood intensity indicators with the projection pursuit model
Authors: Wang Lina , Lian Yanqing , Chen Xiaohong 
Published: September 2017

Abstract
Identifying the various factors that affect the intensity of a flood event, such as its duration and volume, is essential for strategic planning and flood management. Further, quantifying the impacts of these major factors on flood intensity using the contribution rate is essential, but technically challenging. In this study, the authors have adopted the projection pursuit model to quantify the contribution rates of peak flood stage and peak flood discharge, flood duration, and total flood volume (the maximum 12-, 24-, and 72-hour flood volumes) in the Wujiang River in Southern China. This study showed that peak flood discharge and total flood volume were the two dominant factors impacting flood intensity. Although flood duration can be a major factor for some flood events, it contributed the least to flood intensity for most of the historic flood events studied. Likewise, the maximum 24-hour and 72-hour flood volumes contributed little to flood intensity. Findings from this study not only demonstrated the successful adoption of the projection pursuit model for contribution rates, but also provided critical information for planning and managing the regional hydraulic resources in the Wujiang River.

Published: September 2017

Fish protein is oxidased easily during storage. The oxidation reaction rate can be approached through the order to zero or first order. The objective of this research was to study the oxidation rate during storage by determining the amount of activation energy (Ea) and constant change (k). The results showed that the increased of temperature storage from 0 °C to 40oC can increased the k value from 0.0617 to 0.311. The carbonyl content of red snapper protein isolate can be increased to higher level as storage temperature increase to 40 °C with higher level increase at higher temperature. The activation energy of oxidation reactions that cause oxidation of the protein is 42.015 Kj/mol.K to zero order. Kinetics increase in protein carbonyls: the higher the temperature storage protein isolate red snapper (Lutjanus sp), the greater the value of a constant (k) is obtained. Kinetics studies show that an increase in the rate of reaction of oxidative damage fish protein (Lutjanus sp) during storage by following zero order reactions.

Do Firms Strategically Disseminate? Evidence from Corporate Use of Social Media
Authors: Jung Michael J. , Naughton James P. , Tahoun Ahmed , Wang Clare 
Published: September 2017

ABSTRACT
We examine whether firms use social media to strategically disseminate financial information. Analyzing S&P 1500 firms' use of Twitter to disseminate quarterly earnings announcements, we find that firms are less likely to disseminate when the news is bad and when the magnitude of the bad news is worse, consistent with strategic behavior. Furthermore, firms tend to send fewer earnings announcement tweets and “rehash” tweets when the news is bad. Cross-sectional analyses suggest that incentives for strategic dissemination are higher for firms with a lower level of investor sophistication and firms with a larger social media audience. We also find that strategic dissemination behavior is detectable in high litigation risk firms, but not low litigation risk firms. Finally, we find that the tweeting of bad news and the subsequent retweeting of that news by a firm's followers are associated with more negative news articles written about the firm by the traditional media, highlighting a potential downside to Twitter dissemination.

Authors: Camacho Judith Elena Kurmen 
Published: September 2017

La astaxantina es un pigmento natural ampliamente distribuido en la naturaleza y de gran interés comercial como colorante y por sus diversas propiedades como pigmento y bioactivas. El Haematococcus pluvialis es un alga verde que acumula carotenoides, principalmente astaxantina cuando es expuesto a condiciones de estrés. Sin embargo, en la literatura no se encuentran estudios sistemáticos que permitan determinar las condiciones de estrés que mejor favorezcan la acumulación de astaxantina para una producción industrial más rentable. Para tal fin se debe establecer inicialmente la línea base de comportamiento de H. pluviales a condiciones de cultivo estándar, propósito del presente trabajo mediante la revisión teórica de las diferentes condiciones de crecimiento de H. pluviales en los medios de cultivo reportados relacionados con la mayor producción de astaxantina, para lo cual se tienen en cuenta valores de pH, temperatura, CO2, aireación, luz, ciclos luz/oscuridad, agitación, deficiencia de nitrógeno y fósforo.

Authors: Siswoyo Damper Dwijo , Utami Endang Sri 
Published: September 2017

Mekanisme perdagangan di Bursa Efek Indonesia menjadi salah satu instrumen bagi pelaku pasar modal untuk masuk ke dunia investasi di Indonesia. Dalam perkembangannya BEI Self Regulatory Organization (SRO) berusaha untuk membuat kebijakan yang terbaik bagi pasar modal di Indonesia. Pada tanggal 6 januari 2014 sistem perdagangan tentang satuan perdagangan dan fraksi harga saham dirubah oleh BEI. Menurut studi peristiwa, suatu pengumuman atau informasi di pasar modal diukur untuk membuktikan apakah informasi yang masuk ke pasar menimbulkan reaksi pasar. Oleh karena itu penelitian ini bertujuan untuk memperoleh bukti empiris mengenai reaksi pasar terhadap suatu pengumuman yang diukur dengan abnormal return dan trading volume activity. Penelitian ini termasuk studi peristiwa, menggunakan metode market adjusted method dalam mencari abnormal returnnya. Periode jendela yang digunakan adalah 8 hari sebelum peristiwa, 1 hari saat peristiwa dan 8 hari sesudah peristiwa. Jumlah sampel sebanyak 59 emiten dari sepuluh sektor industri berdasarkan JASICA, yang terdaftar di BEI Tahun 2014. Data yang digunakan sekunder dari data pasar Bursa Efek Indonesia yang kemudian diolah dengan one sampel kolmogorov-smirnov dan paired sampel t-test untuk mengetahui ada tidaknya perbedaan average abnormal return (AAR), rerata trading volume activity(TVA) sebelum dan sesudah peristiwa. Hasil dari penelitian ini membuktikan bahwa sepanjang periode pengamatan tidak terdapat perbedaan antara AAR sebelum dan AAR sesudah peristiwa. Dan terdapat perbedaan rerata TVA sebelum dan rerata TVA sesudah peristiwa pada lima sektor industri yaitu sektor pertanian, sektor aneka industri, sektor industri barang konsumsi, sektor properti dan real estate, dan sektor insfratruktur, utilitas dan transportasi. Kelima sektor ini menunjukan aktivitas volume perdagangan yang meningkat sesudah terjadinya peristiwa. Secara garis besar penelitian ini membuktikan bahwa pengumuman tidak sepenuhnya mempunyai kandungan informasi yang material untuk membuat pasar bereaksi sehingga menambah keuntungan bagi investor dan meningkatkan likuiditas saham.

Time-dependent Perpendicular Transport of Energetic Particles for Different Turbulence Configurations and Parallel Transport Models
Authors: Lasuik J. , Shalchi A. 
Published: September 2017

Abstract
Recently, a new theory for the transport of energetic particles across a mean magnetic field was presented. Compared to other nonlinear theories the new approach has the advantage that it provides a full time-dependent description of the transport. Furthermore, a diffusion approximation is no longer part of that theory. The purpose of this paper is to combine this new approach with a time-dependent model for parallel transport and different turbulence configurations in order to explore the parameter regimes for which we get ballistic transport, compound subdiffusion, and normal Markovian diffusion.
Stellar Mass Function of Active and Quiescent Galaxies via the Continuity Equation
Authors: Lapi A. , Mancuso C. , Bressan A. , Danese L. 
Published: September 2017

Abstract
The continuity equation is developed for the stellar mass content of galaxies and exploited to derive the stellar mass function of active and quiescent galaxies over the redshift range

. The continuity equation requires two specific inputs gauged from observations: (i) the star formation rate functions determined on the basis of the latest UV+far-IR/submillimeter/radio measurements and (ii) average star formation histories for individual galaxies, with different prescriptions for disks and spheroids. The continuity equation also includes a source term taking into account (dry) mergers, based on recent numerical simulations and consistent with observations. The stellar mass function derived from the continuity equation is coupled with the halo mass function and with the SFR functions to derive the star formation efficiency and the main sequence of star-forming galaxies via the abundance-matching technique. A remarkable agreement of the resulting stellar mass functions for active and quiescent galaxies of the galaxy main sequence, and of the star formation efficiency with current observations is found; the comparison with data also allows the characteristic timescales for star formation and quiescence of massive galaxies, the star formation history of their progenitors, and the amount of stellar mass added by in situ star formation versus that contributed by external merger events to be robustly constrained. The continuity equation is shown to yield quantitative outcomes that detailed physical models must comply with, that can provide a basis for improving the (subgrid) physical recipes implemented in theoretical approaches and numerical simulations, and that can offer a benchmark for forecasts on future observations with multiband coverage, as will become routinely achievable in the era of JWST.
Retrieval Analysis of the Emission Spectrum of WASP-12b: Sensitivity of Outcomes to Prior Assumptions and Implications for Formation History

Abstract
We analyze the emission spectrum of the hot Jupiter WASP-12b using our HELIOS-R retrieval code and HELIOS-K opacity calculator. When interpreting Hubble and Spitzer data, the retrieval outcomes are found to be prior-dominated. When the prior distributions of the molecular abundances are assumed to be log-uniform, the volume mixing ratio of HCN is found to be implausibly high. A VULCAN chemical kinetics model of WASP-12b suggests that chemical equilibrium is a reasonable assumption even when atmospheric mixing is implausibly rigorous. Guided by (exo)planet formation theory, we set Gaussian priors on the elemental abundances of carbon, oxygen, and nitrogen with the Gaussian peaks being centered on the measured C/H, O/H, and N/H values of the star. By enforcing chemical equilibrium, we find substellar O/H and stellar to slightly superstellar C/H for the dayside atmosphere of WASP-12b. The superstellar carbon-to-oxygen ratio is just above unity, regardless of whether clouds are included in the retrieval analysis, consistent with Madhusudhan et al. Furthermore, whether a temperature inversion exists in the atmosphere depends on one’s assumption for the Gaussian width of the priors. Our retrieved posterior distributions are consistent with the formation of WASP-12b in a solar-composition protoplanetary disk, beyond the water iceline, via gravitational instability or pebble accretion (without core erosion) and migration inward to its present orbital location via a disk-free mechanism, and are inconsistent with both in situ formation and core accretion with disk migration, as predicted by Madhusudhan et al. We predict that the interpretation of James Webb Space Telescope WASP-12b data will not be prior-dominated.

Abstract
TCR signaling pathways cooperate to activate the inducible transcription factors NF-κB, NFAT, and AP-1. In this study, using the calcium ionophore ionomycin and/or PMA on Jurkat T cells, we show that the gene expression program associated with activation of TCR signaling is closely related to specific chromatin landscapes. We find that calcium and kinase signaling cooperate to induce chromatin remodeling at ∼2100 chromatin regions, which demonstrate enriched binding motifs for inducible factors and correlate with target gene expression. We found that these regions typically function as inducible enhancers. Many of these elements contain composite NFAT/AP-1 sites, which typically support cooperative binding, thus further reinforcing the need for cooperation between calcium and kinase signaling in the activation of genes in T cells. In contrast, treatment with PMA or ionomycin alone induces chromatin remodeling at far fewer regions (∼600 and ∼350, respectively), which mostly represent a subset of those induced by costimulation. This suggests that the integration of TCR signaling largely occurs at the level of chromatin, which we propose plays a crucial role in regulating T cell activation.

Authors: Azémar Marc , Hildenbrand Bernd , Haering Brigitte , Heim Manfred E. , Unger Clemens 
Published: September 2017

Purpose We conducted a pilot trial to assess the tolerability, clinical benefit and antitumoral efficacy of modified (hydrolysed) citrus pectin (MCP) in 49 patients with various solid tumors in an advanced state of progression. MCP are hydrolysed from polysaccharide pectin fibers, derived from citrus fruits and acting as a ligand for Galectin-3. Preclinical investigations revealed an efficient inhibition of tumor development and metastasis in various tumor models. Patients and Methods The treatment consisted of the oral intake of 5 g MCP three times a day. One cycle of therapy was defined as 4 weeks of treatment. Objectives were clinical benefit (pain, functional performance, weight change), safety, tumor response (RESIST criteria) and quality of life (EORTC QLQ30). Results 49 patients were enrolled, 29 patients were able to be evaluated for clinical benefit after 2 cycles of treatment. All patients tolerated the therapy well without any severe therapy-related adverse events. After 2 cycles of oral intake of MCP, 6/29 patients (20.7%) had an overall clinical benefit response associated with a stabilization or improvement of life quality. On an intent to treat basis 11/49 patients (22,5%) showed a stable disease (SD) after 2 cycles and 6/49 patients (12,3%) had a SD for a period longer than 24 weeks. One patient suffering from metastasized prostate carcinoma showed a 50% decrease in serum PSA level after 16 weeks of treatment associated with a significant increase of clinical benefit, quality of life and decrease in pain. Conclusion MCP seems to have positive impacts especially regarding clinical benefit and life quality for patients with far advanced solid tumors. The presented preliminary data encourage us to further investigate the role of MCP in cancer prevention and treatment.
