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 parameters of facial blood supply were studied in patients with systemic lupus erythematosus and systemic scleroderma using a non-contact imaging photoplethysmography method synchronized with an electrocardiogram. Statistically significant differences in the amplitude and time of arrival of the pulse wave to different areas of the face were revealed in sick patients compared with the control group. © 2024 IEEE.

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.

Dense single-atomic 14×3-reconstructed Pb layer on Si(111): Structural and superconducting properties

Physical Review B 2023年第11期108卷 115428-115428页

作者： L. V. Bondarenko A. Y. Tupchaya Y. E. Vekovshinin D. V. Gruznev Tatiana V. Utas A. N. Mihalyuk N. V. Denisov A. V. Zotov A. A.

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.

Chlorophyll fluorescence parameters were assessed for three Zea mays cv. grown under polarized light. It is shown that there was no stress in groups grown under polarized radiation. The greater values of photosynthetic parameters were observed in Early ripening gourmet 121 and Golden Batam cv. grown under polarized light in comparison with plants grown under non-polarized treatment.

Highly regular thermochemical laser-induced periodic surface structures (TLIPSS) were produced on the thin Ti metal film deposited on a curved side surface of optical fiber using femtosecond IR laser pulses. The significant dependence of structures regularity on the laser polarization direction relative to the fiber axis was revealed. Results of TLIPSS formation on fiber tip and their practical applications are presented.

The necessity of integrating an intelligent decision support system (DSS) in the professional activities of laser-based additive manufacturing (LBAM) process engineers is discussed. The advantages of applying an ontological two-level approach to the formation of semantic information for developing an ontology-based DSS are highlighted. Its key feature is that ontological models are clearly separated from databases and knowledge bases formed on their basis. A set of related ontological models is presented as the basis for the intelligent DSS that is currently being developed. The composition of the set of models, the purpose of its components, and the possible types of relations between them are described. The set includes ontologies of reference databases on LBAM equipment and materials, an ontology for an archive of laser processing technological operation protocols, an ontology of a knowledge bases on the settings of laser processing modes and an ontology of the mathematical model database. The ensemble of ontological models is implemented on the IACPaaS cloud platform using its tools. Ontologies, databases and knowledge base, as well as DSS, are part of the LBAM knowledge portal, which was created and is being developed on the platform. This portal is intended to accumulate and further use the knowledge and experience collected by different technologists. In the future, it will facilitate the reduction of the number of preliminary experiments required to identify a suitable solution.

The article presents the results of the development of a method for the automatic formation of reference speeds for autonomous unmanned aerial vehicles of multirotor type, performing specified missions (such as monitoring of the sea and coastal territory in order to track populations of rare and endangered species, as well as evaluating the potential volumes of biological resources) singly or as part of a group (in formation). At the same time, the trajectories of these aircraft are set by smooth spatial curves - parametric splines of the third order, which makes it easy to adjust the specified trajectories during the mission. In order to maintain a high speed of movement of vehicles along trajectories with high accuracy of movement and saving formation, it is proposed to adjust the specified speed directly during the mission in such a way that the thrusters can ensure their required movements, taking into account the restrictions on the thrust vectors. At the same time, a simplified model of the dynamics of a quadcopter was used to calculate the values of reference speeds, taking into account the influence of wind force, environmental resistance, gravity and the total thrust vector of the propellers. The systems synthesized on the basis of this method can be implemented even on low-power onboard computing devices of unmanned aerial vehicles.
