High-mobility poly-Si thin-film transistors fabricated by a novel excimer laser crystallization method

High-mobility poly-Si thin-film transistors (TFTs) were fabricated by a novel excimer laser crystallization method based on dual-beam irradiation. The new method can reduce the solidification velocity of the top Si layer by heating the bottom Si layer of the Si/SiO/sub 2//Si/glass substrate structure by means of laser irradiation not only from the front side but also from the back side. The grain size of poly-Si film was enlarged up to 2 mu m. The field-effect mobilities of the TFT exceeded 380 cm/sup 2//V-s for electrons and 100 cm/sup 2//V-s for holes. >
Quantifizierung von Brain-Shift-Effekten in MR-Aufnahmen

EINLEITUNG Bei neurochirurgischen Eingriffen kommen heute häufig computergestützte Navigationssysteme zum Einsatz. Diese Lokalisationshilfen übertragen den Operationsplan, den der Chirurg anhand präoperativ gewonnener CToder MR-Aufnahmen ausgearbeitet hat, während des Eingriffs in das Koordinatensystem des Patienten. Auf diese Weise können im Sinne einer minimalen Schädigung des Patienten optimale Zugangswege eingehalten werden, und die Identifizierung von Tumorgrenzen wird vereinfacht. Die Neuronavigation geht bislang von der Annahme aus, daß das Gehirn ein starrer Körper ist, der sich zwischen dem Zeitpunkt der präoperativen Aufnahme und der Operation nicht verformt. Diese Voraussetzung ist allerdings in der Realität nicht erfüllt: Das Hirngewebe ist elastisch und kann sich durch mechanische Einwirkungen verformen. Bei der Trepanation und der Eröffnung der Dura fließt Hirnflüssigkeit (CSF Cerebro Spinal Fluid) ab, und das Gehirn verschiebt sich aufgrund der Schwerkraft. Ebenso hat die Tumorresektion Veränderungen an der Hirngeometrie zur Folge. Für alle derartigen Effekte wurde der Begriff "Brain-Shift" geprägt. Ziel der vorliegenden Arbeit war es, qualitative und quantitative Aussagen über Brain-Shift zu machen. Erfahrungswerte über das Ausmaß und die Lokalisation von Veränderungen sollen es dem Arzt ermöglichen, die Abweichungen zwischen OP-Plan und Patient besser einschätzen zu können.
LAPAROSCOPY IN PAEDIATRIC SURGERY – OUR EXPERIENCE AT SRMC

Resistance to contemporary broad spectrum âlactams mediated by extended spectrum âlactamases (ESBL) is an increasing problem world wide. The epidemiology of ESBL producing Enterobacteriaceae and the genotypic determinants in an ICU setting in India is largely unknown. The available phenotype tests can sometimes be misleading as more than one type of resistance can be detected in a single isolate or more than one gene is harbored by the same isolate. In the present study, fourteen isolates of E. coli and K. pneumoniae that were antibiotic resistant in a E-strip test were selected. Presence of the blaTEM and blaSHV genotypes among these isolates was screened by PCR. While, four resistant isolates showed no specific amplicons for these two genes, four others carried both the genes. The others either carried the TEM or the SHV type only. This first report from India, clearly highlight the epidemiology of the prevalent genes among the isolates from our ICU.
Isothermal and isochronal annealing experiments on irradiated commercial power VDMOSFETs

The paper presents results of a study of post-irradiation effects in two types of gamma-ray irradiated power VDMOSFETS, commercially available from different manufacturers. Isothermal annealing with constant and switching gate bias, as well as isochronal annealing have been performed. The application of charge-pumping measurements in commercial three-terminal VDMOSFETs is also discussed. Besides enabling insight into the post-irradiation response of investigated devices, obtained results point out some interesting post-irradiation phenomena.
The Impact of Macroeconomic Factors on Banks Liquidity Risk: Evidence From Pakistan

The aim of the study is to identify the factors that influence liquidity risks of the banks by considering the panel of 18 top listed banks in Pakistan during a period of 2010 -2016. The study employed panel random effect regression model to absorb time-invariant shocks, which gives robust inferences. The results of liquidity risk confirmed that the country’s economic growth and price inflation further escalates liquidly risk while, FDI inflows reduces liquidity risks in Pakistani’s banks, thus it is concluded that bank’s liquidity risks required easy monetary policy to advancing loans and charging low interest rate, which ultimately will increase ROA, and ROE, while it would helpful to decrease high risk of bank’s liquidly in a given country.
Unemployment across the Euro Area: The Role of Shocks and Labor Market Institutions

This paper analyses the impact of shocks and labor market institutions on unemployment across the Euro Area (EA) from 1999 to 2013. Specifically, I apply an empirical methodology to identify the direct effects of shocks and labor market institutions on unemployment, on the one hand, and the indirect effects of labor market institutions on changing the transmission of shocks to unemployment, on the other hand. The shocks consist of: 1) total factor productivity (TFP) shocks, 2) the real long-term interest rate, 3) labor demand shocks, 4) ECB money supply shocks and 5) ECB unsystematic monetary policy shocks. The labor market institutions cover the unemployment benefit system, active labor market policies (ALMPs), employment protection laws (EPLs), the system of wage determination and the labor tax wedge. The results suggest that the real interest rate and labor demand shocks significantly affect the unemployment rate in the EA. As for labor market institutions, EPLs play a favorable role in reducing unemployment. In contrast, a higher tax wedge tends to have an adverse effect on unemployment, not only directly increasing unemployment but also indirectly amplifying the effects of shocks on unemployment.
TOPICAL ISSUES OF PHILOSOPHICAL ANTHROPOLOGY

Purpose. The article is aimed to substantiate the view on the phenomenon of laughter as a subject of semiotic analysis, which leads to the following tasks: to reveal the possibilities of semiotics application in the study of laughter nature; to analyze the phenomenon of laughter as a cultural and natural phenomenon, as a sign and as an attribute; to consider the place of laughter in culture, which is understood as a sign system. Theoretical basis. The semiotic approach proceeds from the fact that human lives in the world of signs, all the surrounding reality can be interpreted as a sign system. The basic concept of semiotics is the concept of a sign. The theoretical basis of the article is understanding the culture as a sign-symbolic system. Laughter is considered as a phenomenon ontologically rooted in human culture. At the same time, laughter is on the edge of culture. The research is based on the work of semiotic authors, cultural researchers, and the researchers of laughter. Originality. The originality lies in the application of the semiotic method to the research of laughter phenomenon, consideration of the dialectics of natural and cultural, signedness and non-signedness, manifested in the phenomenon of laughter. Conclusions. Laughter is considered as a psychophysiological phenomenon (attribute) and as a cultural phenomenon (sign). Laughter acts as an emotional manifestation, a physiological reaction, but socially and culturally mediated. In any case, laughter indicates an emotional or cognitive state of a human. Laughter acts as a process and result of the interpretation of a sign, a reaction to a sign. Laughter is a form and a means of communication. Being a natural phenomenon, in the process of social evolution, laughter acquires signedness, is integrated by culture as a sign system, and, at the same time, maintains a connection with nature. Thus, laughter occupies an ambivalent position between nature and culture. In the phenomenon of laughter, the dual state of human is revealed. In laughter, boundaries are blurred, the unity and opposition of natural and cultural, biological and social, soul and body, thought and feeling, sign and attribute are manifested.
Assessment of Seasonal Energy Efficiency Strategies of a Double Skin Façade in a Monsoon Climate Region

As climate change and global warming have become two of the most significant environmental issues today, the double-skin facade (DSF) is getting considerable attention as an energy-efficient passive design. This study is aimed at assessing the seasonal energy efficiency strategies of a DSF targeting library facilities in the climate region with hot summers and cold winters. Toward this end, this study was conducted in four steps: (i) establishment of seasonal energy-efficient strategies; (ii) application of seasonal energy-efficient strategies; (iii) analysis of energy saving effect by season; and (iv) life cycle cost and life cycle CO 2 analyses for selecting an optimal DSF. Results show that a shaft box DSF energy model (EM S ) #2, which applied winter strategies, was optimal with an energy saving rate of 4.13%, while a multi-story DSF energy model (EM M ) #5, which applied summer strategies, was optimal with an energy saving rate of 12.67%. In terms of savings to investment ratio (SIR 40 ) and breakeven point (BEP 40 ), the multi-story DSF (3.20; 9 years) was superior. The results of this study can be used for (i) seasonal energy efficiency strategies of a DSF in East Asian monsoon climates, and (ii) as a guideline for the application of a DSF both in existing and new buildings.

Taking Stock: A Meta-Analysis of Work Engagement in the Hospitality and Tourism Context

Although a number of empirical studies on work engagement have been conducted in the context of hospitality and tourism, few efforts have been made to consolidate previous findings in this area. Hence, this article explores the current stage of work engagement studies and meta-analyses the relations of work engagement with its antecedents and outcomes in the hospitality and tourism context. Through a systematic review, 134 empirical studies (N = 43,043) published from 2008 to September 2020 were identified. Given that the findings include the trends within work engagement studies and the effect sizes and variabilities of associated relationships, this study contributes to the hospitality and tourism literature by providing a useful reference for future researchers. The findings are discussed in light of their theoretical and practical implications.
Determining the Effect of Pod and Grain Moisture Content on Threshing Loss and Damage of Navy Beans

ABSTRACT TIMELY harvesting of navy beans is essential for low threshing loss, freedom from impact damage to the bean and good quality. Stepwise regression techniques were used to develop threshing loss and damage models from field data. Threshing loss depended upon pod moisture content and showed varietal differences. Damage, including split and checked beans as well as total dam-age, depended upon combine cylinder speed and grain moisture content. Careful adjustment of the combine during harvest is required to mini-mize both threshing loss and damage to the crop.
Evaluation of Telemedicine Use for Anesthesiology Pain Division: Retrospective, Observational Case Series Study

Background An increasing number of patients require outpatient and interventional pain management. To help meet the rising demand for anesthesia pain subspecialty care in rural and metropolitan areas, health care providers have used telemedicine for pain management of both interventional patients and those with chronic pain. Objective In this study, we aimed to describe the implementation of a telemedicine program for pain management in an academic pain division in a large metropolitan area. We also aimed to estimate patient cost savings from telemedicine, before and after the California COVID-19 “Safer at Home” directive, and to estimate patient satisfaction with telemedicine for pain management care. Methods This was a retrospective, observational case series study of telemedicine use in a pain division at an urban academic medical center. From August 2019 to June 2020, we evaluated 1398 patients and conducted 2948 video visits for remote pain management care. We used the publicly available Internal Revenue Service’s Statistics of Income data to estimate hourly earnings by zip code in order to estimate patient cost savings. We estimated median travel time and travel distance with Google Maps’ Distance Matrix application programming interface, direct cost of travel with median value for regular fuel cost in California, and time-based opportunity savings from estimated hourly earnings and round-trip time. We reported patient satisfaction scores derived from a postvisit satisfaction survey containing questions with responses on a 5-point Likert scale. Results Patients who attended telemedicine visits avoided an estimated median round-trip driving distance of 26 miles and a median travel time of 69 minutes during afternoon traffic conditions. Within the sample, their median hourly earnings were US $28 (IQR US $21-$39) per hour. Patients saved a median of US $22 on gas and parking and a median total of US $52 (IQR US $36-$75) per telemedicine visit based on estimated hourly earnings and travel time. Patients who were evaluated serially with telemedicine for medication management saved a median of US $156 over a median of 3 visits. A total of 91.4% (286/313) of patients surveyed were satisfied with their telemedicine experience. Conclusions Telemedicine use for pain management reduced travel distance, travel time, and travel and time-based opportunity costs for patients with pain. We achieved the successful implementation of telemedicine across a pain division in an urban academic medical center with high patient satisfaction and patient cost savings.
A Scalable Control Strategy for CHB Converters in Photovoltaic Applications

Renewable energy sources are becoming more relevant in recent decades in power generation, leading to investment in developing efficient systems. Specifically, in photovoltaic energy, modular converters are attracting interest since their characteristics enable them to work at high voltage and optimize the generated energy. However, the control strategies found the literature limit the scalability potential of modular converters. The main aim of this paper is to propose a scalable control strategy for a grid-tied CHB (Cascaded H-Bridge) converter for large-scale photovoltaic power plants. The control proposed is able to take full advantage of converter scalability and modularity, being based on the parameters needed for bipolar sinusoidal PWM (Pulse Width Modulation), and thus reducing the calculus required and simplifying its implementation. Power imbalances are overcome including the zero-sequence vector injection to allow power exchange between phases. Furthermore, the parameter used for power factor control has been discretized and discretization time analysis shows that the control strategy is stable and does not require a high-speed communication channel. For validation purposes, simulations are conducted on a downsized 12 H-bridge model.
Evaluation of Some Inflammatory Biomarkers and Environmental Predictors in Children with Acute Lymphoblastic Leukemia

Acute Lymphoblastic Leukemia in children became a public health concern due to great progress in cure rates. Inflammation plays a crucial role in disease induction and progression as well as in response to treatment. The aim of the present work is to screen the inflammatory status in a cohort of pediatric patients with ALL and to define any treatment or socio-demographic variables related to its aggravation. The study included 79 cases of pediatric cancer patients diagnosed with ALL at the out-patient clinic of the National Cancer Institute in Egypt. Participants responded with their parents to complete the designed questionnaire and a blood sample was taken for assessment of cortisol, C-reactive protein, serum alpha amylase, triglycerides and total cholesterol using ELISA and colorimetric techniques as applied. The study findings showed prominent decrease in cortisol level with mean value of 119 nmol/l, outstanding rise in CRP that reached the mean value of 84 mg/L and elevated level of triglycerides (183 mg/dl). The significant decrease in cortisol was found accompanying higher compliance to treatment, increased hospitalization and early stages of treatment Total cholesterol and alpha amylase showed to be within normal ranges (185 mg/dl and 26 U/L, respectively). As a conclusion, ALL pediatric cancer patients could be suffering from chronic stress that is attributed to both the disease manifestations and treatment procedures. The increased CRP level could be a consequence of the low cortisol level and could be disease and/or treatment related.
Measuring wood chatoyance

ABSTRACT Wood often shows visible colour anisotropy, appearing different when seen from different angles with respect to lighting and fibres direction. This phenomenon is commonly known as chatoyance, and it is practically invisible on some wood species (like olive) while being evident indeed on other species (like sapele). Generally, this phenomenon can be evaluated using a simple gonioreflectometer provided with a light source and a digital camera. This research is aimed at defining a method for quantifying chatoyance that can be replicated by any lab with generic tools. To this aim, the steps required for the measurement are explained and analysed one by one. The method is then tested against lighting intensity variation showing stability in a wide range. Then some tests are repeated with a different camera showing some difference but an overall similar set of results. Based on these preliminary results, the method is considered stable and repeatable. Once frozen, the method is systematically applied to obtain about 4600 measurements from specimens of 75 different wood species (or groups of species); some species systematically show high (or low) chatoyance.
Effectiveness of a chatbot for eating disorders prevention: A randomized clinical trial.

OBJECTIVE Prevention of eating disorders (EDs) is of high importance. However, digital programs with human moderation are unlikely to be disseminated widely. The aim of this study was to test whether a chatbot (i.e., computer program simulating human conversation) would significantly reduce ED risk factors (i.e., weight/shape concerns, thin-ideal internalization) in women at high risk for an ED, compared to waitlist control, as well as whether it would significantly reduce overall ED psychopathology, depression, and anxiety and prevent ED onset. METHOD Women who screened as high risk for an ED were randomized (N = 700) to (1) chatbot based on the StudentBodies© program; or (2) waitlist control. Participants were followed for 6 months. RESULTS For weight/shape concerns, there was a significantly greater reduction in intervention versus control at 3- (d = -0.20; p = .03) and 6-m-follow-up (d = -0.19; p = .04). There were no differences in change in thin-ideal internalization. The intervention was associated with significantly greater reductions than control in overall ED psychopathology at 3- (d = -0.29; p = .003) but not 6-month follow-up. There were no differences in change in depression or anxiety. The odds of remaining nonclinical for EDs were significantly higher in intervention versus control at both 3- (OR = 2.37, 95% CI [1.37, 4.11]) and 6-month follow-ups (OR = 2.13, 95% CI [1.26, 3.59]). DISCUSSION Findings provide support for the use of a chatbot-based EDs prevention program in reducing weight/shape concerns through 6-month follow-up, as well as in reducing overall ED psychopathology, at least in the shorter-term. Results also suggest the intervention may reduce ED onset. PUBLIC SIGNIFICANCE We found that a chatbot, or a computer program simulating human conversation, based on an established, cognitive-behavioral therapy-based eating disorders prevention program, was successful in reducing women's concerns about weight and shape through 6-month follow-up and that it may actually reduce eating disorder onset. These findings are important because this intervention, which uses a rather simple text-based approach, can easily be disseminated in order to prevent these deadly illnesses.

Indigenous Therapeutics of Alzheimer: A Review of Ayurvedic Herbs from its Ethnobotany to Phytotherapy

Ayurveda, often known as Ayurvedic medicine, is a customized system of the traditional system of medicine with historical roots in the Indian subcontinent. This alternative medicine system has been used for more than 5,000 years in India, and it is grounded on a holistic view of treatment that stimulates and supports equilibrium in diverse facets of human life: the body, soul, and mind. A great variety of herbs and plants are used in Ayurveda for numerous advantages; however, the popular Ayurvedic medicinal plants and formulations that are used to delay the aging of the human brain and improve memory consist of Ashwagandha (Withania somnifera), Turmeric (Curcuma longa), Brahmi (Bacopa monnieri), Shankhpushpi (Convolvulus pluricaulis, Evolvulus alsinoides, and other species), gotu kola (Centella asiatica), and guggulu (Commiphora mukul and correlated species) and a preparation identified as Brāhmī Ghṛita, containing Brahmi, Vacā (Acorus calamus), Kuṣṭha (Saussurea lappa), Shankhpushpi, and Purāṇa Ghṛita (old clarified butter/old ghee). One of the extremely common progressive neurodegenerative disorders is Alzheimer s disease (AD), which is characterized by profound memory loss ample enough to hinder social and occupational functioning. Globally, more than 20 million people are affected by this most common form of dementia. AD is characterized by a stealthy loss of memory, allied functional decline, and behavioral disturbances. With modern scientific methods, it is anticipated that this description can be further explored to disclose novel therapeutic pointers and push-start additional studies on the use of Ayurvedic medicine to prevent and treat AD. This paper reviews the clinical effects of a number of generally used types of herbal medicines to treat AD.
