Photometric evolution of seven recent novae and the double-component characterizing the light curve of those emitting in gamma rays

The BVI lightcurves of seven recent novae have been extensively mapped with daily robotic observations from Atacama (Chile). They are V1534 Sco, V1535 Sco, V2949 Oph, V3661 Oph, MASTER OT J010603.18-744715.8, TCP J1734475-240942 and ASASSN-16ma. Five belong to the Bulge, one to SMC and another is a Galactic disk object. The two program novae detected in gamma-rays by Fermi-LAT (TCP J1734475-240942 and ASASSN-16ma) are Bulge objects with unevolved companions. They distinguish themselves in showing a double-component optical lightcurve. The first component to develop is the fireball from freely-expanding, ballistic-launched ejecta with the time of passage through maximum which is strongly dependent on wavelength (~1 day delay between B and I bands). The second component, emerging simultaneously with the nova detection in gamma-rays, evolves at a slower pace, its optical brightness being proportional to the gamma-ray flux, and its passage through maximum not dependent on wavelength. The fact that gamma-rays are detected at peak flux level differing by 4x from novae at the distance of the Bulge seems to suggest that gamma-ray emission is not a widespread property of normal novae. We discuss the advantages offered by high-quality photometric observations collected with only one telescope (as opposed to data provided by a number of different instruments), and observe the effects of: wavelength dependence of a fireball expansion, recombination in the flashed wind of a giant companion, subtle presence of hiccups, super-soft X-ray emission on and off. Four program novae (V2949 Oph, V3661 Oph, TCP J18102829-2729590, and ASASSN-16ma) are found to have normal dwarf companions, while V1534 Sco contains an M3III giant, V1535 Sco a K-type giant, and MASTER OT J010603.18-744715.8 a sub-giant.
Spatial Relations in the Indonesian Locative Preposition of “Di Atas”: a Study of Cognitive Semantics

This study examines the spatial relation of the preposition "di atas" (above, over, on) in Indonesian using cognitive semantic theory. This study aims to discover (i) the conceptual structure of the preposition “ di atas ” spatial relation and (ii) its extended use in the conceptual mapping. This study used descriptive qualitative method. The cognitive data were collected from three groups of subjects, each consisting of ten people. These three groups of subjects are also used as the source triangulation to elicit the conceptual structure of the preposition "di atas" (above, over, on). Meanwhile, the data on the preposition’s extended use in the conceptual mapping were collected from online media. The results suggest that the conceptual structure of the preposition "di atas" (above, over, on) has two kinds of image schemas, namely (i) the VERTICALITY image schema which is based on its orientation and (ii) the ANTARA image schema and the TOPANGAN image schema which are based on its topology. The two kinds of image schemas are general in nature and are specified as definitive lingual units based on the speaker's different perceptions of the position of the related entities. Another important research finding is that prepositions that have been seen as closed words can be used metaphorically through conceptual mapping. This shows that prepositions have an important role in structuring human mind. The results of the study also found and reinforced the construal nature of meaning conceptualization. results of the data analy sis show that the preposition “ di atas ” is also used to represent spatial relations in which there are abstract entities such as sample data (7).
Depression, Acculturative Stress, and Social Connectedness among International University Students in Japan: A Statistical Investigation

(1) This study aims to examine the prevalence of depression and its correlation with Acculturative Stress and Social Connectedness among domestic and international students in an international university in Japan. (2) Methods: A Web-based survey was distributed among several classes of students of the university, which yielded 268 responses. On the survey, a nine-item tool from the Patient Health Questionnaire (PHQ-9), the Social Connectedness Scale (SCS) and Acculturative Stress Scale for International Students (ASSIS) were used together with socio-demographic data. (3) Results: The prevalence of depression was higher among international than domestic students (37.81% and 29.85%, respectively). English language proficiency and student age (20 years old) showed a significant correlation with depression among domestic students (β = −1.63, p = 0.038 and β = 2.24, p = 0.048). Stay length (third year) also displayed a significant correlation with depression among international students (β = 1.08, p = 0.032). Among international and domestic students, a statistically significant positive correlation between depression and acculturative stress, and negative associations of social connectedness with depression and acculturative stress were also found. (4) Conclusions: The high prevalence of depression, and its association with Acculturation stress and Social Connectedness, among the students in this study highlight the importance of implementing support programs which consider the role of Acculturation and Social Connectedness.
Actions and Conceptions: Exploring Initial Literacy Teaching Practice for Adults

ABSTRACT Given that it is a delicate task to meet the educational needs of adult emergent readers in a second language setting, this study serves to explore the teaching practice of teachers working with learners of initial literacy and second language. Based on a situated learning perspective, data from 16 lesson observations of nine teachers is analysed. The findings show that teachers initiate and negotiate learning activities, strive to get the students to understand words and other symbols, facilitate participation within and outside the classroom and negotiate the acceptable student behaviour. These findings suggest that Literacy Education and Second Language Learning for Adults (LESLLA) teaching and learning is a particular practice, where the teachers’ actions are intertwined with those of the learners and with the teachers’ conceptions of the learners. In that way, the teachers’ actions do not only speak of the learners, but also of their own professional identity.
Relative Age Effect in Handball Players of Spain

This study analyzes the effect of relative age in the selection process of handball players for licensed club teams in the Murcia region and the Murcia Regional Handball teams. To this end we studied gender, date of birth and player category in a total of 846 handball players (762 of them in licensed clubs from the Murcia Regional Handball Federation, henceforth FBRM and 84 players in Murcia regional teams respectively) in the children’s, junior and youth categories. Comparisons were made and differences were analyzed with χ2 and Z tests and the Bonferroni correction. The analysis of results according to quarter and semester of birth revealed statistically significant differences both for licensed clubs and for Murcia Regional handball team players. The gender and player category analysis showed statistically significant results only in the case of category in regional teams. Thus RAE is confirmed in the samples analyzed, this effect being stronger amongst regional team players.
Evaluation of antioxidant and antibacterial interactions between resveratrol and eugenol in carboxymethyl cellulose biodegradable film

Abstract The aim of present study was to compare the in vitro antioxidant and antibacterial properties of carboxymethyl cellulose (CMC) films containing resveratrol (RES) and eugenol (EUG), alone and in combination, and to calculate the dose interactions between them. At first, the total phenolic content of CMC films was evaluated. Then, their antioxidant and antibacterial effects of films were determined using DPPH, reducing power, disk diffusion, and broth dilution methods. Finally, concentrations of RES and EUG which showed better results in the CMC films were added in combination forms to calculate their antioxidant and antibacterial interactions. The results showed that addition of RES and/or EUG to CMC films increased the total phenolic content, free radicals scavenging activity, reducing power, and antibacterial activities of the films (p ≤ .05). Gram‐positive bacteria were more susceptible than Gram‐negatives. In addition, the combined use of RES and EUG in CMC films had synergistic antioxidant and antagonistic antibacterial effects. The best results belonged to the film containing RES (8 µg/ml) + EUG (8 mg/ml) (p ≤ .05). Considering the results of the present research, we can utilize CMC biodegradable film containing RES and EUG as a natural active packaging in food industry.
One-sided ideals and derivations of prime rings

The action of derivations on right ideals of prime rings is considered. INTRODUCTION AND STATEMENT OF THE RESULTS Over the last twenty years there has been a great deal of work concerning derivations of prime rings. A number of authors have proved theorems which, roughly speaking, show that the existence of a derivation satisfying certain relations implies that either the ring or the derivation is very special. Also, there are many results giving conditions under which a derivation of a prime ring can be completely determined by the action on some subsets of the ring (such as (two-sided) ideals, Lie ideals, symmetric or skew elements of a ring with involution, etc.). The purpose of this note is to look at the action of derivations on one-sided ideals. The following three theorems present a motivation for the results in this paper. Let R be a prime ring, I be a nonzero (two-sided) ideal of R, and d be a derivation of R. Then: (A) If d3 : O, then the subring generated by d(I) contains a nonzero ideal of R. (B) If charR :# 2 and 3 is another derivation of R such that Ad(I) = 0, then either d = 0 or 3 = 0. (C) If there exists a positive integer n such that d(x)n = 0 for all x E I, then d = 0. The fundamental case of (A) when I = R was proved by Herstein [7, Theorem 1]; a generalization to Lie ideals was obtained by Bergen, Herstein, and Kerr [1, Theorem 3]. The study of compositions of derivations was initiated by a well-known theorem of Posner [10, Theorem 1] which is related to (B). A generalization of (B) to Lie ideals can be, for instance, found in [ 1, Theorem 4]. (C) is due to Giambruno and Herstein [4, Theorem 2] (see also [2, 3]).

Communication of Uncertainty about Preliminary Evidence and the Spread of Its Inferred Misinformation during the COVID-19 Pandemic—A Weibo Case Study

The rapid spread of preliminary scientific evidence is raising concerns on its role in producing misinformation during the COVID-19 pandemic. This research investigated how the communication of uncertainty about preliminary evidence affects the spread of its inferred misinformation in a Weibo case study. In total, 3439 Weibo posts and 10,380 reposts regarding the misinformation of pets transmitting COVID-19 were analyzed. The results showed that attitude ambiguity toward the preliminary evidence and the stage when the evidence was first released with uncertainty were associated with higher numbers of likes and retweets of misinformation posts. Our study highlights the internal sources of misinformation and revisits the contextual perspective in misinformation studies.
Antibiotic resistance in bacteria isolated from the skin of trout in León Province, Spain

Antibiotic resistance among fish pathogens has become a major concern. Integrons play an important role in dissemination of antibiotics resistance genes among the different species of bacteria. This study was designed to determine the antibiotic susceptibility of 20 bacterial isolates were isolated from the skin of brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss) collected from the rivers and fish farms in León Province, Spain and to detect class 1 and 2 integrons in these isolates by PCR to explore the role of these integrons in the antibiotic resistance. The investigated isolates included Pseudomonas fluorescens (P. fluorescens) (n=5), Aeromonas sobria (A. sobria) (n=3), Pantoea agglomerans (P. agglomerans) (n=3), Acinetobacter johnsonii (A. johnsonii) (n=2), Serratia fonticola (S. fonticola) (n=1), Staphylococcus equorum (S. equorum) (n=3), Yersinia kristensenii (Y. kristensenii) (n=2) and Xanthomonas retroflexus (X. retroflexus) (n=1). Antimicrobial susceptibility testing for the isolates revealed that they were sensitive to enrofloxacin (100%) and gentamicin (95%) while resistant to ampicillin (90%) and tetracycline (80%). PCR revealed that all the isolates didn’t harbor class 1 or 2 integrons. Therefore, the indiscriminate use of antibiotics must be restricted and more attention should be paid to biosecurity measures in aquaculture. Also, further studies are needed to assess role of integrons and other genetic elements in antimicrobial resistance in aquaculture.

Molecular Targets and Emerging Therapies for Advanced Gallbladder Cancer

Simple Summary Biliary tract cancers (BTCs) are rare tumors with devastating prognosis. Gallbladder cancer (GBC) is the most common BTC, and even though recent advances have been carried out in the field of clinical management, research for molecular targets for precision medicine is proceeding at slow steps. This review discuss the molecular targets highlighted to date, focusing on clinical trials exploring the efficacy of precision medicine and immunotherapeutic compounds for the treatment of advanced GBC. Points of strength and weakness of each molecular biomarker are discussed, designing new landscapes for new therapeutic approaches for this malignancy, and suggesting new roles for cytotoxic agents, to date considered the gold standard for patients’ clinical management. Abstract Biliary tract cancers (BTCs), for their low incidence, have been often considered together. Gallbladder cancer (GBC) is the most common biliary tract malignancy, characterized by late diagnosis and poor prognosis, and although it is considered a rare tumor in western countries, other areas of the world show considerable incidence rates. In 2010, results from the large phase III ABC-02 clinical trial on GBC identified the gemcitabine and cisplatin combination as the most effective first-line regimen for both GBC and other BTCs. Since then, various systemic therapies have proven active in BTCs in both first- and second-line settings. Molecular profiling has highlighted important genetic differences between GBC and other BTCs, opening new ways for targeted therapy in advanced disease where standard chemotherapies show marginal benefit. Genome-wide data analysis have shown that GBC molecular landscape offer possible strategies for precision medicine approaches, and a better molecular understanding of the GBC is needed to better stratify patients for treatment. In this review, we discuss the molecular targetable agents for GBC, including the results that emerged by clinical trials exploring new treatment strategies.
Precession effect of the gravitational self-force in a Schwarzschild spacetime and the effective one-body formalism

Using a recently presented numerical code for calculating the Lorenz-gauge gravitational self-force (GSF), we compute the O(m) conservative correction to the precession rate of the small-eccentricity orbits of a particle of mass m moving around a Schwarzschild black hole of mass M? m. Specifically, we study the gauge-invariant function ? (x), where ? is defined as the O(m) part of the dimensionless ratio (? r/? )2 between the squares of the radial and azimuthal frequencies of the orbit, and where x=[Gc-3(M+m)? ]2/3 is a gauge-invariant measure of the dimensionless gravitational potential (mass over radius) associated with the mean circular orbit. Our GSF computation of the function ? (x) in the interval 0
Universals and Cultural Differences in Forming Personality Trait Judgments From Faces

Previous research has shown high cross-cultural consensus in personality trait judgments based on faces. However, the information that was provided in these studies included extrafacial features, such as hairstyle or clothes. Such styling information can be intentionally chosen by target persons to express who they are. Using a well-developed and validated Western face model, we were able to formalize the static facial information that is used to make certain personality trait judgments, namely, aggressiveness, extroversion, likeability, risk seeking, social skills, and trustworthiness judgments. We manipulated this information in photographs of Asian and Western faces with natural-looking results. Asian and Western participants identified the enhanced salience of all different personality traits in the faces. Asian participants, however, needed more time for this task. Moreover, faces with enhanced salience of aggressiveness, extroversion, social skills, and trustworthiness were better identified by Western than by Asian participants.
A Real-Time Steel Surface Defect Detection Approach With High Accuracy

Surface defect inspection is a key step to ensure the quality of the hot rolled steel surface. However, current advanced detection (DET) methods have high precision but low detection speed, which hinders the application of the detector in actual production. In this work, a real-time detection network (RDN) focusing on both speed and accuracy is proposed to solve the problem of steel surface defect detection. RDN takes ResNet-dcn, a modular encoding, and decoding network with light weights, as the basic convolutional architecture whose backbone is pretrained on ImageNet. To improve the detection accuracy, a skip layer connection module (SCM) and a pyramid feature fusion module (PFM) are involved into RDN. On the standard dataset NEU-DET, the proposed method can achieve the state-of-the-art recognition speed of 64 frames per second (FPS) and the mean average precision of 80.0% on a single GPU, which fully meets the requirements of the detection accuracy and speed in the actual production line.

Morphometric study of various foramina in the middle cranial fossa of the human skull

Purpose: To study the morphological details and analyse the morphometry of the various foramens in the dry human skulls of Indian population. Materials and Method: Sixty four dry skulls of unknown sex and of Indian origin were used in this study which was carried out at the Department of Anatomy and forensic medicine. The parameters used were incidence, longitudinal diameter, transverse diameter, distance from midline, distance from petrous apex, and distance between right and left foramen. Result: The mean sizes of the foramen ovale on the right and left sides were 7.45x1. 1 mm and 7.61x1. 15 mm. We found that completely ossified pterygospinous ligament passed immediately inferior to the foramen ovale and also presence of bony septa within the foramen. The foramen spinosum was present bilaterally in 90% of the skulls. The mean sizes on the right and left sides were 2.54x0. 8 mm and 1.97x0. 7 mm. Foramen Vesalius is one of the most inconsistent foramen of the skull. In this present study this foramen was present in only 25% of the studied skulls. Conclusion: Results shows comparison of mean and standard deviation of maximum dimensions of the right and left sided foramens of the middle cranial fossa. No statistically significant differences between both sides were observed except the carotid canal. The results of this study can be helpful for anatomists and surgeons who approach the middle cranial fossa for various procedures. Keywords: Foramina-Middle cranial fossa, Foramen rotundum, Foramen ovale, Foramen spinosum, Foramen of Vesalius
Optomechanical transducers for quantum-information processing

We discuss the implementation of optical quantum networks where the interface between stationary and photonic qubits is realized by optomechanical transducers [K. Stannigel et al., Phys. Rev. Lett. 105, 220501 (2010)]. This approach does not rely on the optical properties of the qubit and thereby enables optical quantum communication applications for a wide range of solid-state spin- and charge-based systems. We present an effective description of such networks for many qubits and give a derivation of a state transfer protocol for long-distance quantum communication. We also describe how to mediate local on-chip interactions by means of the optomechanical transducers that can be used for entangling gates. We finally discuss experimental systems for the realization of our proposal.
