Authors: Jablonka Kevin Maik , Melpatti Jothiappan Giriprasad , Wang Shefang , Smit Berend , Yoo Brian 
Published: November 2020

The design rules for materials are clear for applications with a single objective. For most applications, however, there are often multiple, sometimes competing objectives where there is no single best material, and the design rules change to finding the set of Pareto optimal materials. In this work, we introduce an active learning algorithm that directly uses the Pareto dominance relation to compute the set of Pareto optimal materials with desirable accuracy. We apply our algorithm to de novo polymer design with a prohibitively large search space.Using molecular simulations, we compute key descriptors for dispersant applications and reduce the number of materials that need to be evaluated to reconstruct the Pareto front with a desired confidence by over 98% compared to random search.This work showcases how simulation and machine learning techniques can be coupled to discover materials within a design space that would be intractable using conventional screening approaches.

Coronavirus is an RNA virus, positive stranded, and enveloped was first isolated in 1965, can cause symptoms like common cold, severe respiratory symptoms, gastrointestinal, liver and CNS symptoms. WHO announced the original name of coronavirus as COVID 19 in December 2019. This virus has been named as Severe Acute Respiratory Syndrome cov 2 currently and WHO has now declared this virus as emergency of public health concern. More than seventy thousand people in China and 25 other countries have been infected. The confirmed cases of Covid 19 Infection, up to 14th April, 2020 in India were 11,487 and out of which 393 have been deceased and most number of cases were found to be confirmed in Maharashtra (2,684). Animals like camels, cattles, cats, bats probably serve as hosts for coronavirus. Various laboratory investigations like CBC, Real Time-PCR, D-dimer levels, cell culture, electron microscopy, Low platelet count, ESR, CRP levels, Chest CT, X ray, Liver and Kidney Function tests, SOFA (sequential organ failure assessment) score have been useful in diagnosing the causative agent. Since no antiviral treatment has been effective till now, so the transmission can be slowed down by preventive measures like self quarantine, isolation, maintaning distance from one another and use of personal equipments.

Authors: Bodony M. A. 
Published: November 2020

Introduction. The organization of the educational process involves the implementation of ongoing assessment, which provides support for students’ educational activities and the impact on the educational process to improve its effectiveness. One of the elements of the teacher's assessment activity is an assessment judgment, which is formulated by the teacher in the current process of monitoring, diagnosing, analyzing and interpreting the results of students' learning activities and is aimed at informing students about the degree of the planned result achievement, students’ motivation, approval, remark, etc. The study of the teacher's assessment judgments in the context of formative assessment correlates with the problem of reliability, which ensures the consistency, objectivity, fairness and stability of the results of assessment activities.Materials and Methods. The material for the research includes 20 articles published from 2017 to 2020 and devoted to the problems of teachers’ assessment judgments during the process of formative assessment. They were collected by using keywords in the full-text databases of published scientific research which were ScienceDirect and Wiley Online Library. The selected articles were analyzed and summarized from the point of view of considering the factors that influence the teacher's assessment judgments and create conditions for reducing reliability.Results. As a result of the analysis of publications, we identified the following groups of factors that affect the reliability of the teacher's assessment judgments: factors caused by the components of the assessment situation, which include factors related to the subject and object of the assessment, assessment target, scope of the assessment, the basis of the assessment, as well as the use of the assessment tool; factors related to the assessment judgment; external factors.Discussion and Conclusions. The study of the factors influencing the reliability of the teacher's assessment judgments determines the possibilities of increasing the effectiveness of the assessment activities in the process of formative assessment. Understanding the role of each factor creates conditions for preparing recommendations for the teacher to improve the reliability of the current assessment. In addition, on the basis of the classification under consideration, it is possible to conduct empirical studies to clarify the specifics of activating certain factors depending on the goals, conditions and individual characteristics of all participants of the educational process in order to increase the effectiveness of monitoring the achievements of planned educational results and support the educational process.

Published: November 2020

Introduction: Anxiety and depression are both associated with increased morbidity in diabetic population, especially those afflicted with foot ulcer, whereas Erectile Dysfunction (“ED”) and Female Sexual Dysfunction (“FSD”) are amongst the common complication found in diabetes. This study aimed to determine the prevalence of anxiety and depression as primary outcome and sexual dysfunction (“SD”) as a secondary outcome in diabetic patients with and without foot ulcer (“DFU”). Methods: A cross-sectional study was conducted in Hospital Raja Permaisuri Bainun Ipoh, Perak, where 164 diabetic patients were recruited for the purpose of this study. Hospital Anxiety and Depression Scale (“HADS”) were utilised to measure anxiety and depression. International Index for Erectile Function 5 (“IIEF-5”) and the Malay version of Female Sexual Function Index (“MVFSFI”) were used to detect SD. Simple and multiple logistic regressions were referred to in order to evaluate the factors associated with anxiety, depression and SD. Results: In the group with foot ulcer, 36.8% had depressive and anxiety risk respectively compared to without the foot ulcer, 37.5% and 38.5% respectively. Male gender (AOR=6.3,p=0.002,95%CI 1.975, 20.205) and having lower education status (AOR=6.0,p=0.018,95%CI1.36,26.59,) was associated with foot ulcer. High prevalence of SD found in foot ulcer group (52.6%,p=0.006). Those with depression (OR=4.421,95% CI 1.08,18.16,p=0.039) and male gender (OR=18.42,p<0.01,95%CI5.5,-61.62) predicts present of SD. Conclusion: Depression and anxiety prevalent were similar for both with and without diabetic foot ulcer. Several significant predictor factors were identified for DFU group, for anxiety and depression risk and for SD in a diabetes patient. Further studies are required to establish the directional nature of this relationship.

Authors: Kharkov L.V. , Egorov R.I. 
Published: November 2020

Relevance. Today there are more than 150 methods for eliminating congenital defects of the hard and soft palate. However, these techniques do not always lead to high functional results, which leads to repeated surgical interventions and long-term speech therapy rehabilitation. Therefore, there is a problem with the prognosis of such treatment. The search for a marker for assessing the prognosis of surgical intervention is relevant. One of these markers may be the state of the myogenic potential of stem cells.
Objective: to analyze the possibility of preliminary assessment of muscle regeneration, depending on the myogenic potential of stem cells, in order to increase the effectiveness of treatment of children with non-union of the soft palate.
Method. An analytical review of the literature on keywords from the scientometric databases PubMed, Scopus, Web of Science.
Results. Satellite cells represent an adequate system model for studying the biology of adult stem cells. Satellite cells can be considered candidates for cell therapy in muscle regeneration. First, they are one of the most abundant and most accessible cells in our body. Secondly, there is a panel of specific markers that can be used to isolate satellite cells. Third, satellite cells are localized within clear boundaries of the anatomical niche, and signaling mechanisms are currently being studied. Fourth, there is the possibility of recreating muscle injuries in which satellite cells can be studied. Future research aimed at increasing the purification of satellite cells so as to maintain their low differentiation, increase the engraftment potential, as well as new approaches aimed at obtaining satellite cells from iPS cells, will help accelerate the progress and development of drugs for cell therapy in the treatment of muscle degenerative diseases.
Conclusions. The data on the myogenic potential of stem cells, in muscle regeneration, obtained on satellite cell models, can be used to increase the effectiveness of the treatment of children with nonunion of the soft palate.

Authors:   Eye Research Center, Guilan University of Medical Sciences, Rasht, Iran., Medghalchi Abdolreza 
Published: November 2020

Inherited metabolic disorders (IMDs) are a class of genetic disorders. Each metabolic disorder may have different forms with different age of onset, clinical manifestations, severity, and even type of inheritance. Ideally, a group of different specialists, including ophthalmologists, pediatricians, biochemists, and medical geneticists are needed for the final diagnosis and management of IMDs. Because of the importance of the aforementioned issue, we investigated the effect of IMDs on the eye in this review. Metabolic disorders can induce abnormalities in conjunctiva, cornea, lens, retina, optic nerve, and eye motility. In this study, the authors aimed to address the effect of metabolic diseases of amino acids, carbohydrates, and lipids on eye metabolism. Because of the direct toxic mechanisms of abnormal metabolites on the eyes and regarding the effect of eye monitoring on follow-up, management, and treatment of IMDs, a detailed ophthalmological assessment is essential.

Published: November 2020

In the paper the diffraction and interference images received by numerical simulation and experimentally in solving fundamental and applied problems of photonics. Images are structures with a special intensity distribution formed by the initial field and the optical system. To increase the speed of processing of the image data compression method with further implementation in databases is developed. The method of diffraction and interference images compression is based on the intensity quantization. An algorithm for image quantization has been developed: target intensity values have been determined, which allow setting quantization levels, and data visualization techniques, which determine the threshold values for these levels. The algorithm also contains image segmentation by the size of the minimum size of the topological object. The vicinity of topological object is defined under the conditions of a visual registration form and do not crossing with other regions. The topological objects of the diffraction field determine as the maximum, minimum and zero intensity, and in the interference pattern such topological objects are the maximum, minimum and the region of the band splitting. Important parameters are the average value of the intensity of the whole image - which highlights its overall structure and the average value of the intensity of the local segment. The following results were obtained by compressing data from an 8-bit image in grayscale to 2 bits of color depth are enough for an interference image, and to 3 bits, which are enough for a diffraction image. The quantization differences for diffraction images and interference patterns are shown. Data compression ratios are calculated. On the one hand, the application of the obtained results and recommendations is possible in various fields of medicine, biology and pharmacy , which use laser technology, and on the other hand in the development of separate IT identification of topological objects in the light field, optical image processing and decision support in optical problems.
O SURGIMENTO E A IMPORTÂNCIA DA GEOGRAFIA DO TRABALHO
Authors: Cavalcanti Herodes Beserra Cavalcanti Beserra 
Published: November 2020

Esse texto preocupa-se com o tratamento teórico dado ao tema do trabalho na geografia no intuito de apontar sua relevância para compreensão do atual mundo do trabalho. Dentro do quadro da geografia, essa temática por muito tempo apareceu como um assunto periférico, diluído nas análises da geografia econômica. Constituído no plano formal como um objeto a ser descrito, não havia destaque nessas análises os conflitos entre capital e trabalho. No decorrer dos anos de 1970 e 1980, a geografia passa por intensas transformações provenientes da influência do marxismo que levaram a uma crescente discussão de problemáticas sociais no âmbito do espaço social. Com isso, a temática do trabalho começa a ganhar destaque, inicialmente diluída em análises sobre os impacto do desenvolvimento desigual do capital. Posteriormente, o foco das análises dirige-se a temas específicos acerca da organização dos trabalhadores, suas formas de luta e condições de trabalho. Palavras chaves: Geografia; trabalho; espaço; reestruturação produtiva.
