CompHEP-PYTHIA interface: integrated package for the collision events generation based on exact matrix elements

CompHEP, as a partonic event generator, and PYTHIA, as a generator of final states of detectable objects, are interfaced. Thus, integrated tool is proposed for simulation of (almost) arbitrary collision processes at the level of detectable particles. Exact (multiparticle) matrix elements, convolution with structure functions, decays, partons hadronization and (optionally) parton shower evolution are basic stages of calculations. The PEVLIB library of event generators for LHC processes is described.Comment: Standard LaTeX, 4 pages.

Identification of Trace Element-Containing Proteins in Genomic Databases

Development of bioinformatics tools provided researchers with the ability to identify full sets of trace element–containing proteins in organisms for which complete genomic sequences are available. Recently, independent bioinformatics methods were used to identify all, or almost all, genes encoding selenocysteine-containing proteins in human, mouse, and Drosophila genomes, characterizing entire selenoproteomes in these organisms. It also should be possible to search for entire sets of other trace element–associated proteins, such as metal-containing proteins, although methods for their identification are still in development

Production of Welding Fluxes Using Waste Slag Formed in Silicomanganese Smelting

The possibility in principle of using slag, which is formed in the silicon-manganese smelting process, in producing welding fluxes is shown. The composition of and technology used for a new fused flux has been designed. A comparative evaluation of the new flux and the widely used AN-348 type flux was done. It has been proved that the new flux has high strength properties

Some Aspects of Oxidation-Reduction Reactions under Carbon-Bearing Flux Welding

The authors have completed thermodynamic calculations of oxidation-reduction processes under submerged arc welding with application of carbon containing additive. The calculations have shown that carbon, due to its high reducing properties under Т=1950-2200 K, introduced into the system can significantly decrease the amount of non-metallic inclusions in the weld metal and so improve its mechanical properties

Comparison of the Endoscopic Picture in Case of Complications of the upper Gastrointestinal Tract Caused by the Use of Antithrombotic Agents and Non-Steroidal Anti-Inflammatory Drugs

Intaking antithrombotic funds (ATA) and non-steroidal anti-inflammatory drugs (NSAIDs) is one of the most frequent causes of pathology in gastrointestinal (GI) tract.The purpose of the study: comparison of pathological changes of the mucous membrane in the upper GI tract, that occur against the background of ATA and NSAIDs admission.Material and methods. Endoscopic data of two groups of patients taking ATA and NSAIDS have been compared. The first group of 448 patients from the 10th Gastrointestinal Department in N.N. Burdenko Main Military Clinical Hospital was on record from 2013 to 2017. The patients had erosive ulcerous changes of gastrointestinal mucosa, occurred against the background of the ATA admission. The second group comprised 6431 patients with rheumatic diseases. They were hospitalized in the clinic of V.A. Nasonova Research Institute of Rheumatology in the period from 2007 to 2016 and took NSAIDs regularly.Results. Duodenal and gastric ulcer changes in gastric mucosa and duodenal ulcers were identified in 168 (37.5 %) patients taking ATA and in 1691 (26.3 %) patient treated with NSAIDS. Structure of pathology varied. So, against the background of ATA and NSAIDS admission, the number of acute gastric ulceration amounted to 6.5 % and 15.5 % (p < 0.001); acute ulcers duodenal was 2.9 % and 4.9 %; combined ulcerative lesions of gastric and duodenal was 2.9 % and 2.0 %; multiple erosions of gastroduodenal mucosa were 52.4 % and 15.7 % (p < 0.001); single erosion was 35. 1% and 61.6 %. The factor of ulcer history and age ≥ 65 years old increased significantly the risk of duodenal and gastric ulcer changes in patients taking ATA and NSAIDs: OR 5.182 (95% CI 2.701–9.942) and 3.24 (95% CI 2.19–5.34), 4.537 (95% CI 2.036–10.11) and 2.016 (95% CI 1.230–2.917) respectively. Intaking of proton pump inhibitor (PPI) reduced significantly the risk of complications for both ATA and NSAIDs: OR 0.329 (95% CI 0.199–0.546) and 0.317 (95% CI 0.210–0.428) respectively.Conclusion. The structure of pathology of mucous in the upper gastrointestinal tract that arose against the backdrop of ATA and NSAIDs admission is different. The first is characterized by a multiple erosion, while the second one has single acute distal gastric ulcers. The ulcerative history and advanced age of patients increase significantly the risk of complications concerning the gastroduodenal mucosa when using ATA and NSAIDs. PPI is the effective means of preventing this pathology

IMPROVING THE EFFICIENCY OF MASTERING DISTRIBUTED INFORMATION SYSTEMS IN A VIRTUAL COMPUTER LAB BASED ON THE USE OF CONTAINERIZATION AND CONTAINER ORCHESTRATION TECHNOLOGIES

This article discusses issues surrounding the training of specialists in distributed information systems using innovative methods and technologies in a virtual computer lab environment with an integrated knowledge management system. The article clearly shows how complex knowledge, skills, and professional competencies should be taught to IT specialists. It provides a detailed exploration of the architecture of the Virtual Computer Lab (VCL) and describes the successful experience of using the VCL in classes taught by the Department of Systems Analysis and Control at the Dubna State University. The new practice with containers is different compared to hardware virtualization case and effectively complements it for a wide range of practical educational tasks dedicated to the mastering distributed information systems in a virtual computer lab. For the underlying operating system kernel can be used for all containers and improves payload on the north of a similar configuration. The article provides a detailed description of containerization technology to improve the efficiency of IT-training and features of container management in a distributed environment
