The paper describes a cloud-based ontological framework for designing hybrid cloud software systems and services for predicting patient conditions and assessing the risk of critical conditions and events. The proposed solution is based on integrated semantic models for the formation of knowledge, documents, hypotheses and reasoned decisions in medicine. These complexes combine several types of sources for the formation of knowledge bases and various methods and approaches to solving such problems (mathematical modeling, machine learning, and knowledge engineering). For a group of diseases or a section of medicine, knowledge bases are formed about diseases that have passed the verification procedure or that doctors are ready to trust a priori. The means of declarative description of the rules of interpretation of knowledge about the dynamics of the development of diseases and numerical values from predictive models are provided.

The work is devoted to the development of a computing node for processing satellite and spatial data for earth sciences by the example of its implementation as part of the Information and Analytical Environment to support scientific research in geology of the Vernadsky State Geological Museum (SGM ras). The prerequisites for the creation of such a computing node and the requirements for it to solve geological problems are given. An overview of cloud platforms for access to satellite and spatial data and its processing has been presented. Based on the overview a conceptual diagram of a computing node has been proposed and the list of modern technologies required for building it has been determined. The developed node provides tools for searching data from external cloud providers, processing them with various built-in and custom algorithms, as well as tools for visualizing the results. It is an independent web service, although it is part of the Computational and Analytical Geological Environment of SGM ras and is integrated with its services. This allows a wide range of users to access data and processing algorithms provided by computing node, including integrating it into other information systems as a third-party application for processing satellite and spatial data. © 2021 Copyright for this paper by its authors.

In this paper, the gasification of solid fuels in a combined charge of a low-temperature gas generator for flying vehicle equipped with a ramjet engine is considered. The gas generator includes a sequential arrangement of a propellant and a fuel for generation of hydrocarbon gases used to cool the engine before burning in the combustion chamber. A computational model has been developed to simulate the gasification process of porous or granular materials, which uses the laws of conservation of energy, momentum and mass for each phase and takes into account the change in the molar mass of the gas mixture. To implement this model, OpenFOAM has been chosen, which is the leading free, open-source software for computational fluid dynamics and heat transfer. The developed numerical model and OpenFOAM solver have been verified using data from experiments on hexamethylenetetramine (urotropine) gasification;the verification has showed a good agreement between the calculation results and experimental data. A numerical study of the effect of gasifier length on the gasification process at varying inlet gas temperature and inlet gas flow rate has been carried out using polyethylene, polymethyl methacrylate, and urotropine as fuels. It has been shown that as the length of the gasifier increases, its operating time increases not proportionally but less. Moreover, the ratio of the relative change in the length of the gasifier to the corresponding relative change in its operating time may be different for different fuels. It has been revealed that the reason for the disproportionate dependence of the operating time on the gasifier length is the delay in the gasification process at the initial time, while the velocity of the gasification wave doesn’t depend on the gasifier length. An important law has been discovered that when the change in the length of the gasifier is the same as the change in the filtration flow rate of the incoming gas (that is, when the corresponding Strouhal num

Quantum dot synthesis is an increasingly popular technology for the development of optoelectronic devices [1]. Specifically, colloidal quantum dots have shown promise in the infrared range, offering opportunities for the advancement of telecommunications and the creation of infrared light-emitting diodes [2]. One possible approach to enhance the interaction between light and matter is through the use of nanostructures, such as plasmon resonances [3]. However, plasmon resonances often suffer from low quality factors due to internal losses. To overcome this limitation, researchers have explored the use of periodic plasmonic systems, which can significantly increase the quality factors of existing modes [3]. Additionally, metasurfaces, which possess bound states in the continuum (BIC), offer the advantage of infinite radiative quality factors [4]. In this context, a recent study focused on the efficient tuning of a plasmonic metasurface that supports bound states in the continuum. This tuning approach aims to enhance the photoluminescence of HgTe colloidal quantum dots in the infrared region. By leveraging the technological simplicity of this plasmonic metasurface, the researchers were able to achieve improved performance in terms of photoluminescence. Overall, this work demonstrates the potential of plasmonic metasurfaces and bound states in the continuum for enhancing the interaction between light and matter in quantum dot systems. This research opens up new avenues for the development of advanced infrared optoelectronic devices with improved performance and scalability. © 2024 IEEE.

A highly ordered, Pb-dense 14×3-Pb overlayer was grown on Si(111) using the two-step procedure with formation of the 7×3−Pb surface [displaying the 1×1 structure at room temperature (RT)] at the first step and RT deposition of additional Pb at the second step until formation of the 14×3−Pb phase with 1.286 monolayers of Pb is completed. The single-domain orientation of the 14×3−Pb layer persists along the entire surface of the terraces which are typically as wide as dozens of nanometers and in the selected areas might exceed a hundred nanometers. The 14×3−Pb phase hosts the superconductivity with the critical temperature Tc=2.08 K which exceeds all ever reported values for the single-atom Pb layers on Si(111).

Optical fibers sensors have various advantages for precise measurements of wide spectra of parameters. Currently, the deep-learning usage enhances the morphological analysis of the specklegram images. In this study, the design of the full-length optical fiber integration with firm pigtails fixation was used. The Siamese neural network with four convolutional and two fullyconnected layers per each tower was built for assessment of the deformation. The non-loaded specimen specklegram as the first input and image of the specklegram at the loaded state as the second input were used. The accuracy of the trained network with three sets of hyperparameters ranged from 77% to 82.8%. © 2024 IEEE.

Laser-induced periodic surface structures (LIPSS) offer a simple, single-step technique for creating periodic patterns on solids in an ambient air. Combined with metals like gold or silver, LIPSS enhances grating-assisted refractive index (RI) sensors using surface plasmon resonance (SPR). This study analyzes an SPR sensor in the Kretschmann configuration with a periodically modulated silver layer. The modulation is created by LIPSS formed on a titanium-coated glass prism using femtosecond laser pulses, followed by a silver coating. Reflection spectra for wavelengths λ = 600-1700 nm were calculated for various angles of incidence and RI values (1.33-1.4). Unlike a flat sensor with a single resonance, the LIPSS-based sensor shows multiple resonances (λ = 1000-1700 nm) due to modes on inner and outer interfaces. LIPSS reduces resonance spectral width by an order of magnitude, but also reduces sensitivity similarly, weakly affecting the Figure of Merit. The LIPSS-assisted sensor was also tested experimentally. © 2024 SPIE.
