Authors: Pandit Drabindra , Chapagain Narayan P. , Adhikari Binod , Mishra Roshan K. 
Published: November 2018

AbstractThe Sun is an active star and its magnetic field fluctuates from a fraction of a second to a long period of time. The solar wind, CME, solar prominence, solar flares, solar particle and solar filament are the direct result of solar magnetic activity effects on the interplanetary space, Earth’s magnetosphere and ionosphere. The intensity of irruption of these phenomena from the Sun’s surface depends upon its phases. The extreme events affect technology both in space and on the ground.The data obtained from series of observations can help to predict solar activities and safekeeping to the space technology. In this study the cross correlations between IMF Bz, solar wind velocity(Vsw) and interplanetary electric field(Ey) with AE and SYM-H are studied. The results reveal that strong geomagnetic disturbances have high impact on the components of space weather than weak disturbances have.
A study on universality, non-extensivity and Lévy statistics of solar wind turbulence
Authors: Santhosh Kumar G. , Gopinath Sumesh , Prince P. R. 
Published: November 2018

AbstractA number of complex systems arising in diverse disciplines may have certain quantitative features that are surprisingly similar which are classified under the paradigm of “universality”. The non-extensive Tsallis stastical mechanics and Lévy flight patterns provide a novel basis for analyzing non-equilibrium complex systems that may exhibit long-range correlations. The present work studies the scope of employing non-extensive Gutenberg-Richter (G-R) type law for the magnitude distribution of energy of solar wind, in order to investigate the existence of a universal behavior as well as to compute the relations of degree of non-extensivity and Lévy statistics in solar wind turbulence with heliographic distance during different solar cycles.

Published: November 2018

AbstractThe recalibration of the sunspot number series has established a new standard version for sunspot time series that requires updating of prior results based on the calibration. These recent sunspot number corrections mean a change in the results of the previous correlational studies of ISSN with geomagnetic indices, such as the aa-index. In this paper, we investigate the correlation between the old and new sunspot numbers ISSN and SN and their relationship with the aa index through time series, using the methods of Echer et. al (2004), Verma & Trippathi (2016), Stamper et. al (1996), and Feynman (1982).
Distribution of hemispheric solar activity during various phases of solar cycles
Authors: Jayalekshmi G. L. , Prince P. R. 
Published: November 2018

AbstractHemispheric asymmetry is one of the significant parameters related to the action of solar dynamo. Comparison of hemispheric activities during various phases are found out for solar cycles 12 to 23. Asymmetry of solar activity shows extremum values during the cycles 14 and 19. Lowest and highest levels of north-south asymmetry are mainly observed during minimum and maximum phases respectively of solar cycles. A change of phase is found to be existing between the asymmetries at solar maxima and the whole cycle, after solar cycle 15 and 18. Also, for cycles 17-19, the behaviour of the asymmetry is observed to be peculiar and different from that of the other cycles. Periodic behaviour of north-south asymmetry mainly occurs in 8.8 years and noticed very high during the cycles 18-22.

AbstractAimsIn low- and middle-income countries (LMIC) in general and sub-Sahara African (SSA) countries in particular, there is both a large treatment gap for mental disorders and a relative paucity of empirical evidence about how to fill this gap. This is more so for severe mental disorders, such as psychosis, which impose an additional vulnerability for human rights abuse on its sufferers. A major factor for the lack of evidence is the few numbers of active mental health (MH) researchers on the continent and the distance between the little evidence generated and the policy-making process.MethodsThe Partnership for Mental Health Development in Africa (PaM-D) aimed to bring together diverse MH stakeholders in SSA, working collaboratively with colleagues from the global north, to create an infrastructure to develop MH research capacity in SSA, advance global MH science by conducting innovative public health-relevant MH research in the region and work to link research to policy development. Participating SSA countries were Ghana, Kenya, Liberia, Nigeria and South Africa. The research component of PaM-D focused on the development and assessment of a collaborative shared care (CSC) program between traditional and faith healers (T&amp;FHs) and biomedical providers for the treatment of psychotic disorders, as a way of improving the outcome of persons suffering from these conditions. The capacity building component aimed to develop research capacity and appreciation of the value of research in a broad range of stakeholders through bespoke workshops and fellowships targeting specific skill-sets as well as mentoring for early career researchers.ResultsIn the research component of PaM-D, a series of formative studies were implemented to inform the development of an intervention package consisting of the essential features of a CSC for psychosis implemented by primary care providers and T&amp;FHs. A cluster randomised controlled trial was next designed to test the effectiveness of this package on the outcome of psychosis. In the capacity-building component, 35 early and mid-career researchers participated in the training workshops and several established mentor-mentee relationships with senior PaM-D members. At the end of the funding period, 60 papers have been published and 21 successful grant applications made.ConclusionThe success of PaM-D in energising young researchers and implementing a cutting-edge research program attests to the importance of partnership among researchers in the global south working with those from the north in developing MH research and service in LMIC.
Teaching Socrates to First-year Philosophy Students in Iran, Based on Plato's Euthyphro
Authors: Forghani Maryam , Koutlaki Sofia A 
Published: November 2018

AbstractIs it possible to teach philosophy to first-year philosophy students in a way similar to the one Socrates used to teach his interlocutors in the early dialogues? Socrates conducted challenging discussions in the agora of Athens; he began with examining everyday routine concepts, subjected his interlocutors to scrutiny—ἒλεγχος— showed the contradictions in their thinking, and often finally arrived at both his and their ignorance. The starting point of this paper is whether is it possible to teach Socratic philosophy following the Socratic Method. Here, we defend this possibility based on our practical experience of teaching Plato's Euthyphro to first-year students. In particular, the first author taught three groups of first-year philosophy students, for three semesters—Autumn 2016, Spring and Autumn 2017—in the Department of Philosophy at ATU (Allameh Tabataba'i University, Tehran, Iran).
Marking Latin Unseen Translations
Authors: Tuckfield John 
Published: November 2018

The unseen translation - translation of a passage of Latin that the student has not seen before, under constraints of time and with limited access to resources - is a persistent element of Latin courses, especially at school level. It is present in A Level courses in England (for example, OCR 2017), in the Scottish Highers (SQA, 2017), in the New Zealand curriculum (NZQA, 2017), and in Australia (VCAA, 2004; Board of Studies, 2009), to name but a few examples. In Victoria, courses have undergone various changes in the last 30 years, but the unseen has remained a constant: there seems to be a consensus among teachers and examiners that the ability to translate a passage of Latin on the spot is a rigorous and enduring test of at least one aspect of a student's skills in Latin.

Published: November 2018

AbstractThe experience of trauma could be considered a central event in one’s life, such that it could be a core component of one’s identity and life story. Indeed, trauma memories are well-remembered, vivid, intense, and easily accessible (Berntsen & Rubin, 2006). The present study investigated the mediating role of sensory-based trauma memory quality in the relationship between centrality of event and mental health outcomes among child and adolescent survivors of a natural disaster (N= 225) in its immediate aftermath. Results of mediation analyses revealed that centrality of trauma event is related to symptoms of acute stress disorder and depression through sensory-based trauma memory quality (indirect effect 95% C.I. [.06, .11] and [.04, .10], respectively). These findings support the contention that centrality of event is associated to heightened accessibility and vividness of sensory-based trauma memory quality, which in turn is related to an increase in trauma-related symptoms in the immediate aftermath of a natural disaster, where the reminders of trauma are particularly salient in the survivors’ environment and daily activities.

AbstractPersonality characteristics such as extraversion, low agreeableness and low conscientiousness are relevant for alcohol use during adolescence. In addition, having friends who use alcohol is one of the strongest predictors of adolescent alcohol consumption and its negative outcomes. The selection model posits that friends display similar alcohol consumption when their friendships are formed on the basis of common characteristics as, among others, personality. Thus, the aim of this study was to examine the mediation role of peers in the association between the five-factor model of personality and adolescent alcohol use in two cultures. One hundred and twenty Scottish and 221 Spanish respondents, all aged 12-15 years, answered the Alcohol Intake Scale (AIS). Adolescents were asked about the alcohol used at the weekend and also about the alcohol consumed by their friends. Scottish adolescents’ personality was measured by the NEO Personality Inventory-3 (NEO–PI–3). The Junior Spanish version of the Revised NEO Personality Inventory (JS NEO) was used to assess personality in the Spanish sample. Low agreeableness and low conscientiousness correlated with own alcohol quantity in both countries. We performed an independent structural equation modeling for each country. Extraversion (β = .205, p < .05) and low agreeableness (β = –.196, p < .01) for Scottish adolescents, and low conscientiousness (β = –.175, p < .05) for Spanish youths, predicted alcohol use through peer alcohol consumption at weekends. These findings support the relevance of personality traits and peer affiliation in relation to alcohol consumption in adolescence.

Published: November 2018

AbstractThe purpose was to assess the psychometric properties of the French version of the Young Schema Questionnaire - Short Form 3 (YSQ–S3). The main non-clinical sample (N = 605, M = 20.63, 78% women) was divided into two subsamples: One was used for exploratory factor analyses (EFA) and the other was used for confirmatory analyses. Next, internal consistency, convergent validity and criterion-related validity were studied. The EFA to each of the five domains was similar to the theoretical structure postulated by Young. The confirmatory analysis of each of the five domains appeared to favor our solution over a single-factor solution and Young’s solution. The confirmatory factor analyses of high-order structures did not give fully satisfactory results but appeared to favor our solution (RMSEA =.11, CFI =.76, TLI =.71, SRMR =.07, AIC = 58,566.44). In our best model, the reliability (> .70) was satisfactory for fourteen schemas. The relationships between the schemas and the neuroticism, extraversion and psychoticism scores went in the expected directions. Detrimental parental rearing behaviors were linked to high scores for the various schemas. Lastly, 4 schemas differentiated between the clinical and non-clinical groups. In conclusion, the overall psychometric qualities of the French version of the YSQ–S3 allow its use in clinical populations.
MacroH2A1 chromatin specification requires its docking domain and acetylation of H2B lysine 20
Authors: Ruiz Penelope D. , Gamble Matthew J. 
Published: November 2018

AbstractThe histone variant macroH2A1 localizes to two functionally distinct chromatin subtypes marked by either H3K27me3 or H2B acetylations, where it is thought to directly regulate transcription. The recent finding, that macroH2A1 regulates mitochondrial respiration by globally dampening PARP activity, requires the field to re-evaluate which functions of macroH2A1 are due to global effects on cellular metabolism and which are direct effects determined by macroH2A1 chromatin localization. Here, we demonstrate macroH2A1 incorporation into H2B-acetylated chromatin requires a feature in its histone-fold domain, distinguishing this process from incorporation into H3K27me3-containing chromatin in which multiple features of macroH2A1 are sufficient for targeting. In addition, we identify H2BK20 acetylation as a critical modification required to target macroH2A1 to H2B-acetylated chromatin. Our findings have allowed us to definitively establish that macroH2A1’s regulation of an important transcriptional program, the senescence-associated secretory phenotype (SASP), requires its accurate genomic localization.
Solar cell designs by maximizing energy production based on machine learning clustering of spectral variations
Authors: Ripalda J. M. , Buencuerpo J. , García I. 
Published: November 2018

AbstractDue to spectral sensitivity effects, using a single standard spectrum leads to a large uncertainty when estimating the yearly averaged photovoltaic efficiency or energy yield. Here we demonstrate how machine learning techniques can reduce the yearly spectral sets by three orders of magnitude to sets of a few characteristic spectra, and use the resulting proxy spectra to find the optimal solar cell designs maximizing the yearly energy production. When using standard conditions, our calculated efficiency limits show good agreement with current photovoltaic efficiency records, but solar cells designed for record efficiency under the current standard spectra are not optimal for maximizing the yearly energy yield. Our results show that more than 1 MWh m−2 year−1 can realistically be obtained from advanced multijunction systems making use of the direct, diffuse, and back-side albedo components of the irradiance.

Published: November 2018

AbstractThe exocyst is a conserved octameric complex that tethers exocytic vesicles to the plasma membrane prior to fusion. Exocyst assembly and delivery mechanisms remain unclear, especially in mammalian cells. Here we tagged multiple endogenous exocyst subunits with sfGFP or Halo using Cas9 gene-editing, to create single and double knock-in lines of mammary epithelial cells, and interrogated exocyst dynamics by high-speed imaging and correlation spectroscopy. We discovered that mammalian exocyst is comprised of tetrameric subcomplexes that can associate independently with vesicles and plasma membrane and are in dynamic equilibrium with octamer and monomers. Membrane arrival times are similar for subunits and vesicles, but with a small delay (~80msec) between subcomplexes. Departure of SEC3 occurs prior to fusion, whereas other subunits depart just after fusion. About 9 exocyst complexes are associated per vesicle. These data reveal the mammalian exocyst as a remarkably dynamic two-part complex and provide important insights into assembly/disassembly mechanisms.

AbstractThe role of mitochondria dynamics and its molecular regulators remains largely unknown during naïve-to-primed pluripotent cell interconversion. Here we report that mitochondrial MTCH2 is a regulator of mitochondrial fusion, essential for the naïve-to-primed interconversion of murine embryonic stem cells (ESCs). During this interconversion, wild-type ESCs elongate their mitochondria and slightly alter their glutamine utilization. In contrast, MTCH2−/− ESCs fail to elongate their mitochondria and to alter their metabolism, maintaining high levels of histone acetylation and expression of naïve pluripotency markers. Importantly, enforced mitochondria elongation by the pro-fusion protein Mitofusin (MFN) 2 or by a dominant negative form of the pro-fission protein dynamin-related protein (DRP) 1 is sufficient to drive the exit from naïve pluripotency of both MTCH2−/− and wild-type ESCs. Taken together, our data indicate that mitochondria elongation, governed by MTCH2, plays a critical role and constitutes an early driving force in the naïve-to-primed pluripotency interconversion of murine ESCs.
Replication of Resting State-Task Network Correspondence and Novel Findings on Brain Network Activation During Task fMRI in the Human Connectome Project Study
Authors: Nickerson Lisa D. 
Published: November 2018

AbstractThere have been many recent reports highlighting a crisis in replication and reliability of research in psychology, neuroscience, and neuroimaging. After a series of reports uncovered various methodological problems with functional magnetic resonance imaging (fMRI) research, considerable attention has been given to principles and practices to improve reproducibility of neuroimaging findings, including promotion of openness, transparency, and data sharing. However, much less attention has been given to use of open access neuroimaging datasets to conduct replication studies. A major barrier to reproducing neuroimaging studies is their high cost, in money and labor, and utilizing such datasets is an obvious solution for breaking down this barrier. The Human Connectome Project (HCP) is an open access dataset consisting of extensive neurological, behavioral, and genetics assessments and neuroimaging data from over 1,100 individuals. In the present study, findings supporting the replication of a highly cited neuroimaging study that showed correspondence between resting state and task brain networks, and novel findings on activation of brain networks during task performance that arose with this exercise are presented as a demonstration of use of the HCP for replication studies.
Silicon germanium photo-blocking layers for a-IGZO based industrial display

Published: November 2018

AbstractAmorphous indium- gallium-zinc oxide (a-IGZO) has been intensively studied for the application to active matrix flat-panel display because of its superior electrical and optical properties. However, the characteristics of a-IGZO were found to be very sensitive to external circumstance such as light illumination, which dramatically degrades the device performance and stability practically required for display applications. Here, we suggest the use for silicon-germanium (Si-Ge) films grown plasma-enhanced chemical vapour deposition (PECVD) as photo-blocking layers in the a-IGZO thin film transistors (TFTs). The charge mobility and threshold voltage (Vth) of the TFTs depend on the thickness of the Si-Ge films and dielectric buffer layers (SiNX), which were carefully optimized to be ~200 nm and ~300 nm, respectively. As a result, even after 1,000 s illumination time, the Vth and electron mobility of the TFTs remain unchanged, which was enabled by the photo-blocking effect of the Si-Ge layers for a-IGZO films. Considering the simple fabrication process by PECVD with outstanding scalability, we expect that this method can be widely applied to TFT devices that are sensitive to light illumination.
Temperature Dependence of Hourly, Daily, and Event-based Precipitation Extremes Over China

Published: November 2018

AbstractTheoretically, precipitation extremes will increase at a rate of 6–7% with temperature increasing, namely the Clausius-Clapeyron relationship. However, many gauge observations suggest a peak structure of the relationship between precipitation extremes and atmospheric temperature, deviating from the Clausius-Clapeyron relationship. In this study, a comprehensive investigation about the temperature dependence of precipitation extremes (hourly, daily, and event-based) across China is implemented. The results confirm the widespread existence of the peak structure for daily and hourly precipitation extremes and show that (1) there is a generally positive spatial correlation between the precipitation extremes at the peak and temperature at the peak, and this scaling rate is close to the C-C rate; (2) the scaling of event-based extremes for precipitation amount with temperature follows a similar pattern to the daily precipitation extremes while the event-based precipitation intensity does not show a peak structure; (3) the decrease of rain duration is the main cause for the peak structure of the rain amount scaling.
