Using machine learning to speed up new and upgrade detector studies: a calorimeter case

In this paper, we discuss the way advanced machine learning techniques allow physicists to perform in-depth studies of the realistic operating modes of the detectors during the stage of their design. Proposed approach can be applied to both design concept (CDR) and technical design (TDR) phases of future detectors and existing detectors if upgraded. The machine learning approaches may speed up the verification of the possible detector configurations and will automate the entire detector R\&D, which is often accompanied by a large number of scattered studies. We present the approach of using machine learning for detector R\&D and its optimisation cycle with an emphasis on the project of the electromagnetic calorimeter upgrade for the LHCb detector\cite{lhcls3}. The spatial reconstruction and time of arrival properties for the electromagnetic calorimeter were demonstrated.Comment: Talk presented on CHEP 2019 conferenc

Проблемы экспорта транспортно-логистических услуг в контексте интеграционных процессов

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The example of establishment and operation of the joint-stock company «TransContainer» shows the inevitable transformation of economic relations and relations in the system of transport and logistics services that are integrated into the markets of foreign countries when transporting goods by rail. In particular, the question is raised about the scientific interpretation of the commodity essence of the service as an object of civil law and transport logistics as a type of commercial work. Keywords: transport market, transport-logistical service, organizational and legal bases, transport logistics.Текст аннотации на англ. языке и полный текст статьи на англ. языке находится в прилагаемом файле ПДФ (англ. версия следует после русской версии).На примере создания и функционирования акционерного общества «ТрансКонтейнер» показана неизбежная трансформация экономических связей и отношений в системе транспортно- логистических услуг, интегрируемых на рынки зарубежных стран при перевозке грузов по железной дороге. В частности, ставится вопрос о научной трактовке товарной сущности услуги как объекта гражданского права и транспортной логистике как вида коммерческой работы

Formation of Cu, Ag and Au nanofiims under the influence of hydrogen atoms

Due to their electrical properties, thin metallic films are widely used in modern micro- and nanoelectronics. These properties allow solving fundamental problems of surface and solid state physics. Up-to-date methods of producing thin films involve high vacuum or multi-stage processes, which calls for complicated equipment. The authors propose an alternative method of producing thin metallic films using atomic hydrogen. Exothermal reaction of atoms recombination in a molecule (about 4.5 eV / recombination act) initiated on the solid surface by atomic hydrogen may stimulate local heating, spraying and surface atoms transfer. We investigated the process of atomic hydrogen treatment of Cu, Ag and Au metal films, obtained by thermal vacuum evaporation. There are two methods of obtaining nanofilms using atomic hydrogen treatment: sputtering and vapor-phase epitaxy. In the first method, a film is formed by reducing the thickness of the starting film. This method allows obtaining a film as thick as the monolayer. In the second method, a nanofilm is formed by deposition of metal atoms from the vapor phase. This method allows obtaining a film thickness from monolayer to ~10 nm. These methods allow creating nanofilms with controlled parameters and metal thickness. Such films would be technologically pure and have good adhesion

Hydrogen-stimulated migration of metal atoms in «metal — semiconductor» structures

The article presents experimental results of the effect atomic hydrogen has on the Cu—Ge and Ni—Ge structures. It has been shown experimentally that the treatment of structures at room temperature is accompanied by the introduction of metal atoms with an abnormally high concentration in the surface layers of thickness up to 1 mm
