Two-dimensional layers of transition-metal dichalcogenides (TMDs) have been widely studied owing to their exciting potential for applications in advanced electronic and optoelectronic devices. Typically, monolayers of TMDs are produced either by mechanical exfoliation or chemical vapor deposition (CVD). While the former produces high-quality flakes with a size limited to a few micrometers, the latter gives large-area layers but with a nonuniform surface resulting from multiple defects and randomly oriented domains.

Graphene is a promising building block material for developing novel photonic and optoelectronic devices. Here, we report a comprehensive experimental study of chemical-vapor deposited (CVD) monolayer graphene's optical properties on three different substrates for ultraviolet, visible, and near-infrared spectral ranges (from 240 to 1000 nm). Importantly, our ellipsometric measurements are free from the assumptions of additional nanometer-thick layers of water or other media.

Objective: The purpose of this study was to analyze trends in alcohol consumption and mortality and their association with alcohol control measures in Russia between 1990 and 2017.

Method: Analysis of trends for all-cause mortality and alcohol-related mortality, life expectancy, and total adult per capita alcohol consumption and their relationship were conducted. A narrative literature review of alcohol control policies since 1990 was done.

Aim: To evaluate the quality of research articles in psychiatry and addiction medicine published in 2015.

Material And Methods: Five experts analyzed 51 research publications from 13 psychiatric and addiction medicine journals using a standardized questionnaire, which contains 4 general questions (type or results of the study) and 21 questions on the quality of the study.

Results: Only 2 articles (4%) met all criteria, 64% of the articles refer to the methodologically least demonstrative (uncontrolled/one-time, series of cases, non-randomized).

Aim: To evaluate the zero-citation sizes.

Material And Methods: Based on the data of the Russian Science Citation Index the publication activity of four leading institutes in the field of Psychiatry and Addiction is analyzed. The same indices in the field of Neurology were used as a control.

Aim: To compare publishing activities of six research institutes in the field of psychiatry and addiction for 2006-2014.

Material And Methods: An analysis of publishing activities was based on the data of the Russian Science Citation Index (RSCI) of 2006-2014.

Results And Conclusion: The institutes have published 9662 papers that have been cited 39 263 times (4.

Objective: To compare the publication activity of 6 psychiatric institutes based on the data from the Russian Citation Index (RCI).

Material And Methods: Weighted average data of the last five years was selected for analysis: number of publications and citations per author, number of citations per publication, impact factor of journals published the papers. The analysis of the dynamics of publication activity and citations for the period of 2006-2013 for 6 institutes has been performed.

An analysis of the chapter "Medical help for the substance abuses, clinic, treatment of the abusers, biological studies of the abuses' in the Proceedings of the last two Russian congresses of psychiatrists (XIII in 2000 and XIV in 2005) reveals the vast multiplicity of topics. The majority of topics featured in the XIII Congress does not provide any follow-up information in the materials of the XIV Congress thus not allowing to figure out the tendencies or consequences in the field of addiction studies. There is no uniformity in the vocabulary used in the chapter analyzed.

In order to evaluate the use of statistical methods, authors analyzed the articles in the "Korsakoff Journal of Neurology and Psychiatry" 2007-2008 (351 articles) and the "Social and Clinical Psychiatry" 2007 (73 articles). The data were compared to the results of the similar Russian study performed 15 and 20 years ago and the English-language study performed 25 years ago. It has been concluded that the share of articles without any statistical data analysis has decreased dramatically, the use of tables and graphs has become obligatory, t-test has become one of the most used (without any explication of its usage in many cases).

Interrelations of phenomena preconditioned by alcohol consumption were the starting prerequisite of the case study. The annual lethality rates due the to alcohol poisonings (AP) and alcoholic psychosis (APS) morbidity were investigated in 77 Russia's regions during 1991-1999, when the alcohol consumption used to be dynamic in the country--a sharp growth in 1991-1994, a drop in 1995-1998, and a new increase in 1999. The correlation of studied phenomena was observed only in 33 regions.

Aims: The estimation of alcohol-related human losses in Russia in the 1980s and 1990s.

Design: The estimation was made by comparing changes in the total number of deaths and in specific categories, and alcohol consumption in Russia during this time.

Setting: The anti-alcohol campaign, launched in 1985, and the market reforms launched in 1992 were associated with large and rapid changes of alcohol-consumption in Russia.
