Bs0→Ds−a1+(Ds−→ϕπ−,Ds−→K∗0K−)B_s^0 \to D_s^-a_1^+(D_s^- \to \phi \pi^-, D_s^- \to K^{*0}K^-) decay channel in the ATLAS Bs0B_s^0-mixing studies

It is shown, using a track-level simulation, that the use of the $D_s^- \to K^{*0}K^-$ decay channel for $D_s^-$ reconstruction, in additioon with the previously studied $D_s^- \to \phi \pi^-$ mode, enables two fold gain in the ATLAS $B_s^0$-mixing signal statistics through $B_s^0 \to D_s^-a_1$ $B_s^0$-decay channel. A new modification of the amplitude fit method is suggested for the $x_s$ determination. Some general aspects of the $B_s^0$-mixing phenomenon is illustrated by pictures of Casimir Malevich, Maurits Cornelis Escher and Salvador Dali.Comment: 23 pages, LaTex, 7 figures and 4 picture

Management at the enterprise on the basis of ESG principles in the conditions of sanctions pressure

Market development trends that occur continuously provoke the emergence of new approaches, concepts and forms of management of business entities. Special attention should be paid to enterprises and small businesses that are the most flexible and adaptive to external and internal development factors, which is especially relevant at present for the ongoing transformational processes of the economy, market and digitalization of society. The purpose of the study is to improve the management system in small businesses through the new digital solutions for automating marketing in modern conditions. The study examined the prerequisites, prospects and practical experience of using digital solutions for automating marketing activities in the management system of small forms of entrepreneurship in Russia. The research methodology is based on scientific methods of cognition: methods of analysis and synthesis, a comparative method, and is also via the mathematical and statistical methods. The possibilities and potential of applying modern digital solutions by Russian small businesses entities in the country considered in the work will be an important direction for the development of entrepreneurship in the context of digital processes for managing the production and economic activities of domestic enterprises and companies

COMPARISON OF SEARCH ALGORITHM IN THE ORDERED ARRAY

The primary goal of our investigation was to compare the search algorithms on the basis of 'binary search' algorithm. We chose three algorithms - binary search, or dichotomy, golden section algorithm and Fibonacci search, and tested them in our application in the programming language C#. We compared algorithms by the amount of processor CPU cycles (ticks) which algorithm used to find a required element in unsorted array o f random elements, and found the best algorithm for this task

Comparative gustatory responses in four species of gerbilline rodents

Distribution and abundance of carangid larvae in the southeastern Brazilian Bight during 1975-1981

Distribution and abundance of the carangid larvae collected during ten survey cruises in the southeastern Brazilian Bight were analyzed. Trachurus lathami was the most abundant species in the surveyed area with 58.54 % of total carangids taken, followed by Chloroscombrus chrysurus with 15.22 % and Decapteruspunctatus with 12.17 %. Larvae of T lathami and D. punctatus were found all over the continental shelf while the distribution of C. chrysurus larvae was limited to the coastal region. Most of the species occurred all year-around but remarkably during spring and summer. This intensive spawning period of most carangid species seems to be related to the seasonal variation of the hydrographie structure of the southeastern coast of Brazil.No presente trabalho estudaram-se a distribuição e a abundância de larvas de peixes da família Carangidae da costa sudeste do Brasil, entre Cabo Frio (23ºS) e Cabo de Santa Marta Grande (29ºS). As amostras foram coletadas com rede Bongô (malhagens de 0,505 mm e 0,333mm) em arrastos oblíquos, durante dez cruzeiros oceanográficos com o N/Oc. "Prof.W.Besnard", do Instituto Oceanográfico da USP e com N/Oc. "Cruz dei Sur", da PDP-SUDEPE. Foram identificados cinco táxons ao nível de espécie (Trachurus lathami, Chloroscombrus chrysurus, Decapterus punctatus, Selene setapinnis e Selene vomer), além de quatro ao nível de gênero (Oligoplites, Caranx, Serioia e Trachinotus). A espécie mais abundante foi T lathami (58,44% do total de larvas da família Carangidae), seguida por C. chrysurus (15,22%) e D. punctatus (12,17%). T. lathami e D. punctatus apresentaram distribuição ampla por toda a região nerítica, enquanto que C. chrysurus restringiu-se apenas às regiões mais próximas da costa. As larvas de carangídeos foram encontradas durante todas as épocas do ano, mas na primavera e no verão observou-se a maior abundância, o que caracteriza maior intensidade de desova durante estas estações. Esse período de pico de desova relaciona-se, aparentemente, à variação da estrutura hidrográfica da região
