These results confirm the assignment of the sub-ps time constants of previous experimental studies and constitute the first computational evidence for the ultrafast formation of the charge-separated states in Re-sensitized azurin. © The Author(s) 2020.We study the evolution equations for a regularized version of Dirac-harmonic maps from closed Riemannian surfaces. We establish the existence of a global weak solution for the regularized problem, which is smooth away from finitely many singularities. Moreover, we discuss the convergence of the evolution equations and address the question if we can remove the regularization in the end. © The Author(s) 2020.In this work we show that if the frame property of a Gabor frame with window in Feichtinger's algebra and a fixed lattice only depends on the parity of the window, then the lattice can be replaced by any other lattice of the same density without losing the frame property. As a byproduct we derive a generalization of a result of Lyubarskii and Nes, who could show that any Gabor system consisting of an odd window function from Feichtinger's algebra and any separable lattice of density n + 1 n , n ∈ N + , cannot be a Gabor frame for the Hilbert space of square-integrable functions on the real line. We extend this result by removing the assumption that the lattice has to be separable. This is achieved by exploiting the interplay between the symplectic and the metaplectic group. © The Author(s) 2019.We provide several new q-congruences for truncated basic hypergeometric series with the base being an even power of q. Our results mainly concern congruences modulo the square or the cube of a cyclotomic polynomial and complement corresponding ones of an earlier paper containing q-congruences for truncated basic hypergeometric series with the base being an odd power of q. We also give a number of related conjectures including q-congruences modulo the fifth power of a cyclotomic polynomial and a congruence for a truncated ordinary hypergeometric series modulo the seventh power of a prime greater than 3. © The Author(s) 2019.Objective To compare age and protein-energy malnutrition (PEM) - the predispositions - and fever and abnormal leukocyte count (ALC) - the SIRS criteria - in hospitalized children with and without diarrhea. Design A prospective case-control study. Setting A pediatric ward of a general hospital in a low-resource setting. Participants Totally, 445 consecutive admissions to the pediatric ward of a general hospital over a period of 1 year were included in this prospective case-control study; hemodynamically unstable subjects (11) were excluded. Interventions Age, PEM, fever, and ALC were assessed in 59 patients with diarrhea and compared with 375 control patients without diarrhea. Odds ratios with confidence intervals were determined; the chi-square test and binary logistic regression analysis were also performed. Main Outcome Measures Associations of diarrhea with age, PEM, fever and ALC singly and various combinations of predispositions and SIRS parameters. Results Infancy and ALC were significantly associated with diarrhea. PEM or fever alone was not significantly associated with diarrhea; however, the probability of developing diarrhea was significantly higher when a combination of ALC and PEM was observed. The combination of infancy, PEM, and ALC carried a sensitivity of 81·36%; for other combinations, sensitivity varied between 70% and 80%. The combination of infancy and ALC had the lowest sensitivity (59·32%) but the best specificity (61·07%). Conclusion The association/presence of a combination of SIRS parameters (fever and ALC) and predispositions (infancy and PEM) in children with diarrhea may help in deciding whether antibiotic therapy should be initiated. © 2020 Daga et al.Introduction According to rapid growth of innovation in use of technologies in education and learning, blended learning has become an effective method in the student's education. The purpose of this study was to extract the factors related to effective blended learning and compare the viewpoints of students and instructors in this regard. Methods Mixed method model was used in this study. A content analysis approach was employed in the qualitative phase of the study. Seven faculty members and eight master's students of medical sciences selected through purposive sampling participated in the qualitative phase. Individual semi-structured interviews were conducted for data collection. In the quantitative phase, appropriate and relevant items were designed based on the main concepts of theoretical and practical definitions that were extracted in the qualitative phase. Results The results of the qualitative phase were 5 categories and 40 subcategories, including student's capabilities, teacher merits, technological aspects, pedagogic topics and supportive environment. https://www.selleckchem.com/products/crt0066101-dihydrochloride.html Discussion The results of the questionnaire analysis showed no significant difference in student capabilities and supportive environment between the viewpoints of students and faculty members while there were significant differences in other categories. Although new technologies have offered promising opportunities, they do not result in effective education. The results of the present study suggest that a major revision in student and instructor admission and provision of required technical facilities can promote the status of this type of education. On the other hand, instructor empowerment programs in this field can enhance the effectiveness of virtual education. © 2020 Mirmoghtadaie et al.This study explores the perspectives of doctors, nurses, and technicians on the medical clown. A total of 35 subjects were interviewed one on one. Interviews were transcribed and analyzed for common themes. Medical staff outlined novel limitations and views of future directions for the field of medical clowning. Most importantly, many previously unpublished benefits of medical clowns were described. These reported benefits included cost-saving measures for the hospital, increases in staff efficiency, better patient outcomes, and lower stress in medical staff. Given that most of the limitations on medical clowning are financial in nature, these findings have substantial implications for the future of the field. As medical clowning continues to grow, this study outlines the potential for various future research projects within this field of study. © The Author(s) 2020.
