Authors: Morimoto Masahiro , Ozawa Yuya , Naka Shigeki , Okada Hiroyuki
Published: May 2021

Polymer light-emitting diodes (PLEDs) are generally fabricated using the wet process. Although it is difficult to stack multiple layers by the wet process, it is compatible with the lamination process that can be used to fabricate multi-layer tandem type devices. We fabricate tandem type PLEDs composed of two transparent substrates using the lamination process. Stacked red and green PLEDs exhibit additive color mixed emission resulting in orange emission. By careful selection of materials, similar emission is observed from both substrates of the semi-transparent tandem PLEDs because the over-layer does not absorb the emission from the under-layer.

Outer-sphere electron transfer (OS-ET) is a cornerstone elementary electrochemical reaction, yet microscopic understanding is largely based on idealized theories, developed in isolation from experiments that themselves are often close to the kinetic (diffusion) limit. Focusing on graphene as-grown on a copper substrate as a model 2D material/metal-supported electrode system, this study resolves the key electronic interactions in OS-ET, and identifies the role of graphene in modulating the electronic properties of the electrode/electrolyte interface. An integrated experimental-theoretical approach combining co-located multi-microscopy, centered on scanning electrochemical cell microscopy (SECCM), with Raman microscopy and field emission-scanning electron microscopy, together with rate theory and density functional theory (DFT) calculations is used to address OS-ET kinetics of hexaamineruthenium (III/II) chloride, [Ru(NH3)6]3+/2+. The experimental methodology allows spatially-resolved electrochemical measurements to be targeted at distinct regions of monolayer, bilayer and multilayer graphene on copper, with high diffusion rates, to reveal ET kinetics in the order: monolayer > bilayer > multilayer. To rationalize these findings we extended the Schmickler-Newns-Anderson model Hamiltonian for electron transfer and parametrized it using constant potential DFT. Combining this model with rate theory reveals that the difference in kinetics at monolayer and bilayer graphene can be rationalized in the context of a dominantly adiabatic mechanism, where the addition of subsequent graphene layers increases the contact potential, producing an increase in the effective barrier to electron transfer. This study provides a roadmap for the integration of experiments, theory, and simulations in order to understand the nature of heterogeneous electron transfer at complex nanostructured electrode materials.
Expanded Ensemble Methods Can Be Used to Accurately Predict Protein-Ligand Relative Binding Free Energies
Authors: Zhang Si , Hahn David , Shirts Michael R. , Voelz Vincent
Published: May 2021

Alchemical free energy methods have become indispensable in computational drug discovery for their ability to calculate highly accurate estimates of protein-ligand affinities. Expanded ensemble (EE) methods, which involve single simulations visiting all of the alchemical intermediates, have some key advantages for alchemical free energy calculation. However, there have been relatively few examples published in the literature of using expanded ensemble simulations for free energies of protein-ligand binding. In this paper, as a test of expanded ensemble methods, we computed relative binding free energies using the Open Force Field Initiative force field (codename “Parsley”) for twenty-four pairs of Tyk2 inhibitors derived from a congeneric series of 16 compounds. The EE predictions agree well with the experimental values (RMSE of 0.94 ± 0.13 kcal mol−1 and MUE of 0.75 ± 0.12 kcal mol−1). We find that while increasing the number of alchemical intermediates can improve the phase space overlap, faster convergence can be obtained with fewer intermediates, as long as the acceptance rates are sufficient. We find that convergence can be improved using more aggressive updating of the biases, and that estimates can be improved by performing multiple independent EE calculations. This work demonstrates that EE is a viable option for alchemical free energy calculation. We discuss the implications of these findings for rational drug design, as well as future directions for improvement.
Hydroxylamine as a Superior Organocatalyst for Morita-Baylis-Hillman Reaction
Authors: Yadav Veejendra
Published: May 2021

Computational investigations indicate that the use of N,N-dimethylhydroxylamine as organocatalyst enhances the rate of Morita-Baylis-Hillman reaction by lowering the activation energy of the rate-controlling aldol step. The rate enhancement is understood to originate from the a-effect of oxygen on nitrogen in hydroxylamine, which enhances the nucleophilicity of the nitrogen and results in its more effective conjugate addition to the enone to form an advanced and, thus, reactive enolate to participate in the aldol process. The activation energy of the aldol reaction is therefore reduced.
Vacuum-Field Catalysis: Accelerated Reactions by Vibrational Ultra Strong Coupling
Authors: Hiura Hidefumi , Shalabney Atef
Published: May 2021

In conventional catalysis, the reactants interact with specific sites of the catalyst in such a way that the reaction barrier is lowered by changing the reaction path, causing the reaction rate to be accelerated. Here we take a radically different

approach to catalysis by ultra-strongly coupling the vibrations of the reactants to the infrared vacuum electromagnetic field. To demonstrate the possibility of such

vacuum-field catalysis (or cavity catalysis), we have studied hydrolysis reactions under the vibrational ultra strong coupling (V-USC) of the OH stretching mode of water to a Fabry-Pérot microfluidic cavity mode. This results in a giant Rabi splitting energy (92 meV), indicating the system is in the V-USC regime. We have found that V-USC water enhances the hydrolysis reaction rate of cyanate ions by

102-fold and that of ammonia borane by 104-fold. This catalytic ability is found to depend upon the coupling ratio of the vibrational light-matter interaction. Given the vital importance of water for life and human activities, we expect that our finding not only offers an unconventional way of controlling chemical reactions by vacuum-field catalysis but also brings a fresh perspective to science and technology.
Fixation of Closed Transverse Patella Fracture with Cannulated Cancellous Screws and Anterior Tension Band Wiring- A Prospective Study
Authors: Senthil Loganathan  , Raghavendran B  , Thiyagarajan U  , Pradeep J
Published: May 2021

Patella fractures accounts for 1% of all skeletal injuries.  Patella fractures usually need to be treated with accurate reduction and fixation to obtain optimal knee function. Improper reduction of the articular fragments leads to complications like arthritis and quadriceps dysfunction. Tension band wiring and pasting are commonly performed fixation methods. Tension band wiring with K-wires is associated with wire prominence and soft tissue irritation. Cannulated cancellous screw fixation of the fracture and tension band wiring through the cannulated screws avoid the complication of wire migration and breakage.   In our study, we fixed these fractures with cannulated cancellous screws and tension band. This is a prospective study done in SRMC from 2012-2017. A total of 17 Patients with transverse patella fracture are taken into a study, 4mm cannulated cancellous screws with 18 mm stainless steel wire is used for anterior tension band wiring. Extensor retinaculum closure is done for all these patients. All patients had excellent knee function, according to KSS. There was no case of implant prominence or soft issue irritation in any of these patients. One patient had extensor lag. Cannulated cancellous screw with anterior tension band wiring is a reliable, effective and reproducible technique in treating transverse patella fractures.
Violence and abuse among working children in urban and suburban areas of lower Sindh, Pakistan
Authors: Iqbal Meesha , Fatmi Zafar , Khan Kausar , Nafees Asaad
Published: May 2021

Background: Child labourers are exposed to an insecure environment and higher risk of violence. Violence among child labourers is an under-studied phenomenon which requires contextual assessment. Aims: We applied Bronfenbrenner’s ecological model (micro-, exo- and macro-system) to understand the interplay of individual, community, societal and policy context fuelling violence. Methods: Focus group discussions and family ethnographies of child-labourers working in common occupational sectors of suburban areas of Sindh were carried out to gain in-depth understanding of their immediate environment and abuse (micro-system). Frequency of emotional, physical and sexual violence (5–14 years; n = 634) was also determined. Indepth interviews with employers (exo-system, n = 4) and key-informant-interviews of prominent stakeholders in Pakistan (macro-system, n = 4) working against labour/violence were carried out Thematic-content analysis was performed using MAXQDA, version 8.0. Results: We estimated that 21%, 19% and 9% of children suffered from emotional, physical and sexual violence respectively. Child labourers’ interviews indicated the existence of all forms of abuse at home and in the workplace; sexual violence by grandfathers was highlighted (micro-system). Children reported frequent scolding and insults in the workplace along with physical violence that could be fatal (exo-system). The legal environment of violence in Pakistan was considered deficient as it did not address the hidden forms (touching, kissing, etc.; macro-system). Conclusion: We documented that all forms of violence were rampant among the child labourers, and improved efforts and comprehensive legislation is direly needed to alleviate the situation.

Background: Lebanon is part of the global DISCOVER study, a global, noninterventional, multicentre, prospective study with 3-years of follow-up. Aims: The aim of this study is to describe real-world clinical practice in terms of type 2 diabetes mellitus (T2DM) disease management and treatment patterns within Lebanon. Methods: Baseline demographic and clinical parameters were captured on a standardized case report form, according to routine clinical practice at each clinical site. Results: We recruited 348 patients. At the initiation of second-line therapy, mean duration of diabetes was 6.7 [standard deviation (SD) 6.5] years; mean HbA1c and fasting plasma glucose levels were 8.5% (SD 1.6%) and 178.7 (SD 56.5) mg/dL respectively. Almost half the patients were hypertensive (45.1%) or had dyslipidaemia (48.6%). Metformin monotherapy was used as first-line therapy in 56.9% of the patients and upfront dual therapy in 25%. The primary reason for changing first-line therapy was poor glycaemic control. The main factors in choosing the second-line therapy were efficacy, tolerability and hypoglycaemia. Conclusion: Clinical inertia was evident in this cohort of patients as they had suboptimal glycaemic control at the time of enrolment and the initiation of second-line therapy. Treatment intensification is required to reduce diabetes-related adverse outcomes.
Witold Gombrowicz i Bruno Schulz. Biografie równoległe
Authors: Skiba Tymoteusz
Published: May 2021

This article gives an account of the overlapping biographies of Witold Gombrowicz and Bruno Schulz. It frames the events which brought the two writers together with a discussion of their literary debuts in 1933, which preceded their first meeting, and the post-war memories of Gombrowicz, who kept reminiscing about his “deceased friend”. The author describes the meetings and conversations between Schulz and Gombrowicz that took place at the latter’s apartment or in Zofia Nałkowska’s salon, their joint undertakings, such as the publication of open letters in Studio magazine, and their battle with literary critics, whose spiteful comments and attacks were aimed at what they called “young literature”. The article presents testimonies of Gombrowicz and Schulz’s mutual inspirations and interpretations, and discusses texts and events which echo their vigorous correspondence, mostly lost during the Second World War. This mosaic of dispersed facts and memories depicts a great friendship between two artists, who approached each other with curiosity and respect, but also with their typical penchant for self-irony. The idea of parallel biographies was born during the author’s work on the research project Calendar of the Life, Work, and Reception of Bruno Schulz.

Authors: Muslihah Isnawati , Muqorobin Muqorobin
Published: May 2021

Face recognition is an identification system that uses the characteristics of a person's face for processing. There is a feature in the face image so that it can be distinguished between one face and another face. One way to recognize face images is to analyze the texture of the face image. Texture analysis generally requires a feature extraction process. In different images, the characteristics will also differ. This characteristic will be the basis for the recognition of facial images. However, existing face recognition methods experience efficiency problems and rely heavily on the extraction of the right features. This study aims to study the texture characteristics of the extraction results using the Local Binary Pattern (LBP) method which is applied to deal with the introduction of Probabilistic Linear Discriminant Analysis (PLDA). The data used in this study are human face images from the AR Faces database, consisting of 136 objects (76 men and 60 women), each of which has 7 types of images Based on the results of testing shows the LBP method can produce the highest accuracy with a value of 95.53% in the introduction of PLDA.
Importance of Interkingdom Interactions Among Oral Microbiome Towards Caries Development – A Review
Authors: Balakrishnan Kalpana , Sivanesan Divya , Mohan Gaanappriya , Gunthe Sachin , Verma Rama
Published: May 2021

The human microbiome plays a crucial role in health and disease conditions. These microbiomes constitute a structured, coordinated microbial network throughout the human body. The oral cavity harbors one of the extensively diverse bacteria in the human system. Although many studies emphasize bacteriome and its interaction with the host system, very little attention is given to candidate phyla radiation (CPR), fungal components, and its interkingdom interaction in the oral microecology even with advanced techniques. The interkingdom interactions among caries causing microbes trigger the pathogenesis of bacterial diseases and cause ecological shifts and affect the host system. Studying the complex relations among the diverse oral microbiome and its host, especially CPR phyla and fungi, would give a holistic view of the caries etiology. This review provides evidence on the interkingdom interaction that establishes a complex community that could help predict future oral and systemic diseases.

Crucial landmarks, connections, eloquent brain areas that related to the corticospinal tract were emphasized.

Conclusion: So that pointing the importance of such disorders to keep in mind as not to move forward with incorrect operation decision. Trajectory of one of the largest desending pathway, corticospinal tract and the relationship with different diagnosis should be considered.
The Politics of Funding: The Rockfeller Foundation and French Economics, 1945-1955
Authors: Benest Serge
Published: May 2021

Following World War II, the director of the Social Sciences Division at the Rockefeller Foundation, the industrial economist Joseph H. Willits, thought it important to extend its activities to Europe, especially France. His agenda was to strengthen institutional economics and to create modern research centers with a view to stabilizing the political situation. In the postwar decade, almost all economic research centers in France were funded by the Foundation, which helped provide greater autonomy to French economists within academia, but failed to reshape French economic training and research.
The Clinton Healthcare Reform Plan: A Resort to Place
Authors: Brown Tim , Moon Graham
Published: May 2021

Geographers have given little attention to the attempts by the Clinton administration to reform the US health care “system”. This paper considers the use of spatialized language in key documents and debates associated with the reform process. It considers the ways in which the administration exercised a Foucauldian form of governmentality appealing to interest groups and individuals on the basis of notions of place-in-society, place-in-life cycle, place-in-health care system and geographical place. These tactics are set in the context of the identified key principles underpinning the need for reform. The paper concludes by suggesting that whilst Clinton, in his attempts to achieve health care reform, may have appeared politically naive, his strategic use of sense of place was, on the contrary, very perceptive.

Published: May 2021

Video data are uniquely suited for research reuse and for documenting behavioral research methods and findings. However, curation of video data is a serious hurdle for researchers in the behavioral sciences, where data sharing is not the norm. To eliminate the onerous burden of post-hoc curation at the time of publication (or later), we describe best practices in active data curation—curation “as you go”—where data are uploaded immediately after each data collection to allow instantaneous sharing with one button press at any time. We address how to prepare for collecting and sharing identifiable video data; train researchers for accurate and efficient video data curation; and offer solutions when active curation of research video is impossible.
FVS 2.0: A Unifying Framework for Understanding the Factors of Visual-Attentional Processing
Authors: Huang Liqiang
Published: May 2021

Across a broad range of stimulus types and tasks (16 stimulus types × 26 tasks, 1744 observers in total), the present study employed an individual-item differences analysis to extract the factors of visual-attentional processing. Three orthogonal factors were identified and they can be summarized as an FVS 2.0 framework: featural, visual, and spatial strengths. Apart from one exception (low-level motion), the FVS 2.0 framework accounts for the vast majority (95.4%) of the variances in the 25 tasks. Therefore, the three straightforward factors provide a unifying framework for understanding the relationship between stimulus types as well as those between tasks. Combining these and other related results, the role of preattentive features seems to be rather different from the traditional view: visual features are general-purpose, exclusive, innate, constancy-based, and keyword-like. A GEICK conjecture is proposed which suggests that the features are conscious-level keywords generated by the specific brain area of V4 and/or IT and then used by all other brain areas.
Using open spatial data to investigate the importance of salmon streams in the Indigenous cultural landscapes of Southwest Alaska.
Authors: Lim Jonathan S. , Matás Gonzalo José Linares
Published: May 2021

The history of human activity in Southwest Alaska is inextricably linked to the exploitation of its many species of salmonid fish. Alaskan salmonids are anadromous, meaning they live most of their lives at sea, only to return to the river in which they were spawned to reproduce— this makes them a reliable seasonal resource in this environmentally marginal subarctic landscape. Salmonids form a major part of the subsistence lifestyle of modern Native Alaskans, and archaeological evidence suggests that their ancestors experienced population booms and cultural shifts coinciding with the adoption of mass fishing techniques. This was done primarily in response to climate changes, and to sustain burgeoning populations. Analyses of salmonid behavioural patterns are therefore crucial for understanding the lifeways of past peoples in Southwest Alaska. This work outlines a GIS-based methodology for processing an open spatial dataset— the Alaska Department of Fish and Game’s Anadromous Waters Catalog (AWC)— to make it suitable for use in archaeological and anthropological research. AWC shapefiles converted in this manner may be used to identify the most ecologically diverse (and, therefore, productive) anadromous waterways, and the relationship between heritage site distribution and salmon activity along the length of rivers. As a pilot study, we discuss the cultural landscape of the Yup’ik community of Quinhagak in the Yukon-Kuskokwim (Y-K) Delta, and its two active salmon streams— the Agalig (Arolik) and Qanirtuuq (Kanektok) Rivers. There appears to be a strong relationship between the presence of cultural sites associated with fishing (both historic and archaeological) near the mouths of both rivers where the salmon runs begin (the “initial lower course”, or, “ILC”). It also highlights the importance of such rivers as highways to access non-salmonid resources further inland, including hunting and plant harvesting areas. This methodology has a strong potential for assisting in the survey and characterisation of heritage sites elsewhere in Southwest Alaska.

This article discusses the improvement of liquidity regulation mechanisms for commercial banks in developed countries.  This article will consider such concepts as “liquidity”, “liquidity management”, “liquidity management mechanism”, and the existing approaches to its definition, as well as the bank’s information infrastructure, which is necessary and sufficient for the implementation of effective liquidity management. It should be noted that the emphasis will be placed on the aspects and approaches to liquidity management directly by the commercial bank itself, and not on prudential or other norms aimed at assessing the risk of a bank losing its liquidity. The purpose of this article is to consider the existing approaches to liquidity management, their advantages and disadvantages, for possible use in the future as basic ones for the planned study.
Gastric Adenomyoma: A Case Report and Comprehensive Review of the Modern Literature
Authors: D Trocha Steven , A Barré , Schammel Christine , H Fenton , AM Devane , D Trocha Steven
Published: May 2021

Gastric adenomyoma is a rare, benign neoplasm, often mistaken as a gastrointestinal stromal tumor and not properly identified until after surgical excision. The importance of defining the diagnosis in this entity is highlighted by the fact that these tumors do not require surgical excision. General knowledge of this neoplasm is lacking among physicians. In case reports, this tumor was either incidentally discovered and removed or found during workup for nonspecific GI symptoms and removed because of suspicion for gastrointestinal stromal tumor (GIST). Multiple papers state that surgical excision is necessary for diagnostic clarity. We present an updated review of the modern literature and a case of gastric adenomyoma, as well as define an algorithm using histology and immunohistochemical (IHC) stains (desmin, CKIT, DOG1, PDGF and CK7) for the diagnosis of gastric adenomyoma in a noninvasive manner in order to potentially avoid unnecessary surgery.

Vaccinations are very essential for the prevention of harmful diseases. However, the implementation rate of vaccination varies in different parts of the world. Many countries struggle to achieve the maximum immunization ratio due to their vaccination practices and methodologies. However, the authors have developed a solution to strengthen the vaccination procedure. SHIFAYAAB, Proposed Methodology in this paper provides a centralized platform for different healthcare organizations and hospitals, working on various vaccination programs. The idea is to collectively provide a centralized database for the vaccination programs by integrating the platform with the healthcare organizations and hospitals, to enhance and improve the vaccination procedure for the workers as well as the public. SHIFAYAAB proposes automation of the vaccination procedure by replacing the old school vaccine schedule card-reports with autonomous system[1]generated microplans. It will assemble the vaccination records and provide a user-friendly platform for the vaccinators to carry out the vaccination process. It will also provide children parents a platform to keep track of their vaccination progress by monitoring their microplan along with regular notification reminders from the platform.

Methodologies of heat calculation and selection of rational parameters of regenerative burners operation
Authors: Biryukov A. B.
Published: May 2021

Decrease of energy intensity of products is an actual task for all the industries, including steel industry. One of the best solutions to increase energy efficiency of heating facilities is application of recuperative and regenerative burners, which ensure high temperature of air heating. Such high temperatures cannot be achieved at application of heating systems based on central recuperator. It was shown that many countries accomplish studies to perfect recuperative burners and simulation of their thermal operation. However at present there are no universally recognized methodologies of calculation and designing of such equipment. Results of studies presented, which were implemented in three methodologies intended for heat calculation and selection of rational parameters of regenerative burners operation. The methodologies enable also to determine a fuel utilization coefficient for a furnace system based on regenerative burners, to estimate competitiveness of solutions at creation new and modernization existing furnaces comparing with utilization of modern central recuperators. Comparative simplicity of the mathematical apparatus used in the methodologies highlighted, as well as correspondence of the used calculated expressions to the physical nature of the processes taking place. Besides, the methodologies enable during calculation to set the values of important characteristics, which can be reached based on determination of values of basic structure parameters of lining. A scheme of joint application of the elaborated methodologies proposed.

Metallurgical production associates with such processes as crushing, drying and pneumatic transportation of raw materials, roasting, melting etc., in the process of which hard particles and harmful gaseous components are emitted into atmosphere. At pneumatic transportation of raw materials and sand, their concentration in the atmosphere as a rule exceeds maximum permissible concentrations. Existing facilities of dusty flows cleaning in some cases don’t ensure sanitary norms ГН 2.1.6.3492‒17. Technical solutions  proposed  to  clean  gases  in  a  centrifugal  filter,  a  facility  of  complex  gas  cleaning – cyclo-filter and two-stage  system  of high-concentrated gas-dust flows cleaning. Description of the centrifugal filter, cyclo-filter, two-stage facility of gas cleaning design presented. The facility comprises centrifugal filter and ceramic pulse filter. Industrial tests of the centrifugal filter ЦФ2-6-1 under conditions of a system of pneumatic transportation of sand established, that efficiency of gas-dust flows cleaning of sand particles in a  six-channel  filter  can  reach 98.65%.  Application of  two-stage  system  of  gas  cleaning  comprising  centrifugal  filter  and  ceramic pulse filter ФКИ enables to reach residual hard particles concentration at the exit of such a facility of 5 mg/m3, having initial dust level of 127878 mg/m3. Application of such a complex two-stage cleaning facility allows to reach values of 0.1 of maximum permissible concentrations near the source of emissions.

Published: May 2021

This paper investigates the inadequate evidence of usury in the economy in ASIA 5, including Indonesia, Malaysia, Thailand, China, and South Korea, to answer why major religions (Islam, Christianity, Judaism) prohibit usury. We use a qualitative research method of content analysis by collecting several justifiable evidence using source triangulation and method triangulation and combining with quantitative content analysis, which quantifies the qualitative findings and analyzes them quantitatively using Threshold Autoregressive. It is a proxy for forecasting future economic conditions considering each exchange rate regimes and the period of crisis experienced by the five countries. We found that the higher the riba proxied by the interest rate, the more burdening the five countries to recover from the crisis. Moreover, we find that the concept of sharia, which is proxied by direct investment, can boost the economy and can increase economic resilience against the financial crisis, which was evident in three countries, namely Thailand, Malaysia, and China, during the Asian crisis period (1997) to the digital economy era (2020).
