Information Analysis Support for Decision-Making in Scientific and Technological Development

This paper presents the development of an information and analytical system to foster scientific and technological development in a given scientific field. In this work, the main software tools for implementing distributed computing, which involves a set of software components for collecting, processing, and analyzing large amounts of data, are considered. In addition, various approaches for task coordination between different sets of software are discussed and techniques for storing large amounts of data are described. The system architecture and database schema are designed and tested. Nowadays, the intellectualization of individual software agents is a key aspect of a new generation of multiagent systems. For this reason, this paper develops an approach that can organize activities of a large number of software agents to increase system intellectualization through swarm intelligence at the level of individual agents. Three remote servers were used to build and test the system deployment, comprising such components as a platform for monitoring and scheduling workflow, data storage, and a graphical user interface that enables data retrieval and interaction on the Internet

Effect of probiotics on height and weight parameters of young cattle

The main direction of agriculture is the search for effective methods of production to provide the population with the provision and to ensure the food independence of the Russian Federation. The purpose of this study was to determine the effect of feed yeast produced in Russia and abroad on the growth of calves up to six months of age. The scientific and production experiment was carried out on the dairy farm of "Gigant" Agricultural Production Cooperative Collective Farm of the Stavropol Territory. Four groups of ten heads of black-and-white calves were formed according to the principle of analogues. The animals were ten days old. Together with the main diet the calves of the 1st experimental group received I-SAK1026 drug in the amount of 11 g per animal per day, the animals of the second experimental group were fed with "Levisil SC+" drug in the amount of 5 g per animal per day, and the calves of the third experimental group received "Optisaf" drug in the amount of 15 g per animal per day. Changes of linear measurements of growth rate with age were different. The animals of the third experimental group had an advantage in most of the measurements. Compared to the control, they showed more significant results. Based on the results of the study, the following was established. Calves of the third experimental group that received "Optisaf" probiotic were characterized by more significant activity of metabolic processes. The calves of this group were ahead of the control calves in terms of development and growth

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Biological Earth observation with animal sensors

Space-based tracking technology using low-cost miniature tags is now delivering data on fine-scale animal movement at near-global scale. Linked with remotely sensed environmental data, this offers a biological lens on habitat integrity and connectivity for conservation and human health; a global network of animal sentinels of environmen-tal change
