CMS dashboard task monitoring: A user-centric monitoring view

We are now in a phase change of the CMS experiment where people are turning more intensely to physics analysis and away from construction. This brings a lot of challenging issues with respect to monitoring of the user analysis. The physicists must be able to monitor the execution status, application and grid-level messages of their tasks that may run at any site within the CMS Virtual Organisation. The CMS Dashboard Task Monitoring project provides this information towards individual analysis users by collecting and exposing a user-centric set of information regarding submitted tasks including reason of failure, distribution by site and over time, consumed time and efficiency. The development was user-driven with physicists invited to test the prototype in order to assemble further requirements and identify weaknesses with the application

Technology of growing silicon nanotubes

© 2018 Institute of Physics Publishing. All rights reserved. The paper presents the results of studies on silicon nanotubes production in an arc discharge. The features of the experiments, the description of the experimental setup are given. A description of the obtained nanostructures studied on an electron microscope is presented. It is unequivocal to assert that the obtained silicon nanotubes are single-walled, it is not yet possible. But the fact of obtaining silicon nanotubes is indisputable

Discharge creeping along the surface in the process for producing nanomaterials

© Published under licence by IOP Publishing Ltd. In this paper, we propose a new principle of assembling carbon nanoparticles in the plasma of a glow discharge creeping along the surface. In this paper, it is shown that carbon nanoparticles (fullerenes and nanotubes), as well as light fractions of oil, can be produced by means of a glow discharge on the surface of the fuel oil. Single-walled carbon nanotubes of about 10 μm in length were obtained

Search for a signal on intermediate baryon systems formation in hadron-nuclear and nuclear-nuclear interactions at high energies

We have analyzed the behavior of different characteristics of hadron-nuclear and nuclear-nuclear interactions as a function of centrality to get a signal on the formation of intermediate baryon systems. We observed that the data demonstrate the regime change and saturation. The angular distributions of slow particles exhibit some structure in the above mentioned reactions at low energy. We believe that the structure could be connected with the formation and decay of the percolation cluster. With increasing the mass of colliding nuclei, the structure starts to become weak and almost disappears ultimately. This shows that the number of secondary internuclear interactions increases with increasing the mass of the colliding nuclei. The latter could be a reason of the disintegration of any intermediate formations as well as clusters, which decrease their influence on the angular distribution of the emitted particles.Comment: 2 pages and one figur

Carbon nanotubes formation in the decomposition of heavy hydrocarbons creeping along the surface of the glow discharge

The possibility of heavy hydrocarbons decomposition in the plasma of the creeping glow discharge in a magnetic field is investigated. An electron microscopic analysis of carbon deposit on the electrodes and the walls of the discharge chamber, and gas chromatographic analysis formed in the course of the experiment is carried out. The grown carbon nanotubes have a length of about 6,17μm and a diameter of about 18nm

Scientific Communication 2.0: Features of Presenting Scientific Content on German Popular Science YouTube Channels

The article is devoted to the feature’s analysis of the presentation of scientific content on the German-language popular science YouTube channels maiLab and Terra X Lesch & Co. It has been established that, in general, the popular science YouTube channels maiLab and Terra X Lesch & Co. are oriented towards the strategies and forms of presentation of scientific content adopted in the field of science: types of thematic progression characteristic of theoretical discourse (descriptive, explicative and argumentative) are used, as well as scheme of an argumentative statement. It is shown that, in contrast to the objectification mechanism of information exchange, which determines the presentation of scientific content within the scientific community, a personalization mechanism operates in the network of popular science communication, which is determined by the peculiarities of the interaction of the participants in network communication and the polymodality of the Internet as a medium. The authors consider in detail the techniques of intimization, emotionalization, dialogization, metaphorization, visualization and implementation of a narrative pattern. It is noted that these techniques allow bloggers to maintain the attention and interest of their channel subscribers, as well as simplify the presentation of scientific content, making it easier to understand. It is proved that the use of the strategy of personalization of information exchange, which is characteristic of mass media discourse, leads to a consistent violation of the prohibitions existing in theoretical discourse on any explicit manifestation of the subject of speech in a statement. The analysis of the material allows the authors to conclude about the active interaction of different discourses — theoretical and mass media — in their peripheral zones and describe the mechanisms of this interaction
