Architecting the IoT Paradigm: A Middleware for Autonomous Distributed Sensor Networks

Actualizing Internet of Things undoubtedly constitutes a major challenge of modern computing and is a promising next step in realizing the unification of all seamlessly interacting entities, either human users or participating machines, under a shared, coherent architecture. While it has now become common belief that the related solutions should be based on compatible network infrastructure employing widely accepted communication schemes, the specifics of the intermediate system that would act as global interface for all involved “things” are yet to be determined. A rising trend to define such machine-based entities is through cyber-physical systems, in terms of collaborating elements with physical input and output. Certainly, sensor networks constitute the most representative realization of such systems. Taking these issues and opportunities under consideration, this work proposes a bioinspired distributed architecture for an Internet of Things that exhibits self-organization properties to enable efficient interaction between entities modeled as cyber-physical systems, mainly focusing on sensor networks. Furthermore, a middleware has been implemented according to the proposed architecture, which serves the role of the backbone of this network as a multiagent and autonomous distributed system. The evaluation results demonstrate the self-optimization properties of the introduced scheme and indicate global network convergence

The ART-XC telescope on board the SRG observatory

ART-XC (Astronomical Roentgen Telescope - X-ray Concentrator) is the hard X-ray instrument with grazing incidence imaging optics on board the Spektr-Roentgen-Gamma (SRG) observatory. The SRG observatory is the flagship astrophysical mission of the Russian Federal Space Program, which was successively launched into orbit around the second Lagrangian point (L2) of the Earth-Sun system with a Proton rocket from the Baikonur cosmodrome on 13 July 2019. The ART-XC telescope will provide the first ever true imaging all-sky survey performed with grazing incidence optics in the 4-30 keV energy band and will obtain the deepest and sharpest map of the sky in the energy range of 4-12 keV. Observations performed during the early calibration and performance verification phase as well as during the on-going all-sky survey that started on 12 Dec. 2019 have demonstrated that the in-flight characteristics of the ART-XC telescope are very close to expectations based on the results of ground calibrations. Upon completion of its 4-year all-sky survey, ART-XC is expected to detect ~5000 sources (~3000 active galactic nuclei, including heavily obscured ones, several hundred clusters of galaxies, ~1000 cataclysmic variables and other Galactic sources), and to provide a high-quality map of the Galactic background emission in the 4-12 keV energy band. ART-XC is also well suited for discovering transient X-ray sources. In this paper, we describe the telescope, results of its ground calibrations, major aspects of the mission, the in-flight performance of ART-XC and first scientific results.Comment: 19 pages, 30 figures, accepted for publication in Astronomy and Astrophysic

Inclusion criteria: age from 18 to 60 years, 1–2 coma stage (Glasgow-Pittsburgh coma scale of 14–27), ethanol in the blood of more than 2.5%. The patients were randomized into 2 groups: the Study Drug group (SD group) — 67 patients who, in addition to the standard therapy, were injected with the study drug - inosine glycyl-cysteinyl-glutamate disodium in a dose of 3.0 mg/kg; and the Placebo group — 66 patients who, in addition to the standard therapy, were injected with 0.9% sodium chloride solution in a dose of 3.0 mg/kg. Comparative intergroup and intragroup analyses were carried out according to the main clinical, laboratory parameters and EEG monitoring data.Results The study showed a positive effect of the study drug — a reduction in the coma period was noted (from 137 (75; 180) minutes to 78 (50; 155) minutes (p<0.001)), higher values of the Glasgow-Pittsburgh scale were recorded after 3 and 6 hours from the start of the therapy (p<0.01), a reduction in the time of formation of EEG awakening patterns in patients with delta coma activity from 192.2 (161.9; 222.5) minutes to 112.5 (97.6; 127.6) minutes (p<0.001), a decrease in heart rate (p<0.02), a decrease in the number of complaints of weakness and dizziness (p<0.005), in patients with high ALT levels, the frequency of development and severity of tremor decreased (p<0.01). The hepatoprotective effect of the drug was revealed, it was manifested by a decrease in ALT (p<0.001), AST (p<0.001) and direct bilirubin (p<0.03); the effect of the drug on metabolic processes — a decrease in lactate (p<0.02), an increase in BE-ECF (p<0.01), glucose (p<0.01) 3 hours after drug administration, an increase in potassium after 24 hours (p<0.03). The analysis of safety data did not reveal statistically significant differences between the treatment groups, no serious adverse events were recorded.Conclusion The study demonstrated the efficacy and safety of inosine glycyl-cysteinyl-glutamate disodium (Molixan®) in the treatment of severe ethanol poisoning in a single dose of 3.0 mg/kg administered intravenouslyРезюме В статье представлены результаты многоцентрового, рандомизированного, двойного слепого, плацебо-контролируемого клинического исследования эффективности и безопасности препарата инозина глицил-цистеинил-глутамат динатрия (Моликсан®) в терапии острых тяжелых отравлений этанолом.Цель исследования Оценка эффективности и безопасности применения препарата инозина глицил-цистеинил-глутамат динатрия в новом режиме дозировании в терапии тяжелых отравлений этанолом.Материал и методы Материал исследования — данные 133 пациентов с тяжелым отравлением этанолом.

Generation of perturbations by a localized vibrator in the boundary layer of a nonswept wing

Origination and development of perturbations generated by a three-dimensional vibrating surface in the boundary layer on an airfoil with a zero sweep angle is experimentally studied. Surface vibrations were generated by a three-dimensional membrane. It is shown that high-amplitude vibrations of a three-dimensional surface lead to simultaneous formation of two types of perturbations in the boundary layer: quasi-stationary streamwise structures and wave packets accompanying them. The presence of regions with favourable and adverse pressure gradients does not exert a significant effect on evolution of streamwise structures but leads first to attenuation and then to amplification of wave packets
