In this study, the human visual field test technology is established by using an optoelectrical system consisting of a translucent ellipsoid, an area light source, and a landscape scene with an indicator. during the test, the subjects stared at the indicator directly in front of them with one eye and kept their eyeballs still, scanning the light strip with peripheral vision and using the mouse button plus the playback program to record the start and end positions of the scanning light strip in the landscape scene. This method is tested subjectively, and the subject needs to respond during the test. Therefore, before the test, the subject needs to understand the test process and be trained in advance to improve the exam accuracy. In the experiment, fifteen subjects with normal vision and no eye disease were selected. Their visual fields were confirmed normal after a preliminary assessment. The test results showed that the subjects' eyes were within the normal visual field, indicating that this method was feasible. In this research, a digital optical platform for the near visual field is proposed to establish an optoelectric visual field measurement technology. The proposed method is characterized by small size, rapid operation, and easy portability. With the digital LCd and visual imaging technology, both dynamic and static visual fields can be tested. The test data on the eyes' upper, lower, nasal, and temporal sides were consistent with the normal visual field. This shows that this method is feasible and worthy of promotion in the optometry industry. © 2023 IEEE.

VANET (Vehicular Ad Hoc Network) was developed to address the unique challenges of communication in a mobile vehicular environment. This technology can enhance driving safety and traffic control. Moreover, similar principles can be applied to unmanned aerial vehicles and robotics. When transmitting data in moving vehicles, it is challenging as access points and base stations keep changing, requiring handovers between different access points and base stations. Clustering is a popular approach used to address this challenge. Common clustering strategies are based on the proximity, communication range, the density, the application requirements of the moving vehicles, or hybrid of them. In this paper, we propose a clustering strategy based on the application sublayer in the vehicle communication protocol. If two computing devices on the move run the same application, they can be grouped together. The contribution of this research is to develop a clustering mechanism based on the application with very low overhead. We also validate the proposed method through simulations. The simulation results indicate that the proposed method is feasible. © 2023 IEEE.

Today, the world's power system is in transition towards "green" generation in line with the Paris climate agreement of 2015. Emergence of this technology alters existing consumption pattern for mineral resources. Today, center stage is taken by such crucial elements as copper, nickel, lithium, cobalt and, of course, REMs. Permanent REM magnets are pivotal to transition to green and renewable energy. Therefore, in new circumstances the global power system needs different approaches to production and supply chains for key natural resources. Russia's FEC is the world's second largest (after the USA) producer of power resources and third largest in-country consumer of the same (trailing the USA and China). However, there is no full-cycle production of individual REMs and REM-based alloys inside the country, despite one of the largest mineral resource bases of REMs in the world. A clearly apparent global trend shows that the pace of developing new MR sources and the necessary investments do not match acceleration in production of such high tech products as solar batteries, wind power generators (WPG), and electric cars. This is due to the fact that many key MRs (especially REMs) come from a small number of producers located in just a few countries. With this in mind, the paper presents a study of the production chain of NdFeB magnets and electric engines based on them, seen as essential to development of Russia's wind power. Also, economic feasibility of some generation technologies in connection with the ever-increasing power of generators is considered. Basic topologies of electric machines are analyzed as well. The key question of the study is whether rare earth MRs become an incentive for transition to a new energy system in Russia or a bottleneck in the process. © 2023

Self-explanatory artificial intelligence has lately gained prominence as researchers and practitioners strive to make their methodologies more understandable. It is not contentious to assert that researching how individuals explain to one another may be a useful beginning point for explanation in artificial intelligence, given that the majority of this research has focused on publicly explaining decisions or actions to a human observer. However, it is reasonable to say that the vast bulk of self-explanatory artificial intelligence research is based solely on the researchers’ subjective opinions of what constitutes a "good" explanation. Extensive and essential study in science and technology has been conducted on the definition, creation, selection, assessment, and presentation of explanations by humans. This study contends that people use certain cognitive biases and social expectations in the explanation process. This paper covers relevant studies from several fields and makes the case that self-explainable artificial intelligence should expand on some current research. It highlights several key results and explores how they may be combined with research on self-explainable artificial intelligence. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This study introduces a successfully manufactured U-shaped optical fiber sensor integrated with a microfluidics system to detect varying glucose concentrations. It outlines the fabrication process of the microfluidics system, accomplished using a CO2 laser on polymethyl methacrylate (PMMA) material. Through three cycles of experiments involving different glucose concentrations, the results indicate a consistent trend in both resonance wavelength and transmission loss, showing an increase as glucose concentration rises from 5% to 50%. The system demonstrates a high wavelength sensitivity coefficient of 0.114 nm/% with ${R}^{{2}} =0.95$ and a notable transmission loss sensitivity of 0.09 dB/% and ${R}^{{2}} =0.94$ . This advanced system proves to be effective in achieving rapid, sensitive, and cost-efficient glucose monitoring. Consequently, the microfluidics system is deemed suitable for its intended purpose.

An immobilized hydrogen-producing consortium investigated biohydrogen production from food waste using a combination of sodium alginate and cassava rhizome biochar. We investigated the effect of varying the biochar concentration from 0 to 3% and the size of immobilized cells from 1 to 7 mm. Immobilized cells were prepared using 50% (v/v) enriched hydrogen-producing consortium, 2% (w/v) sodium alginate, and 0 to 3% (w/v) cassava rhizome biochar. The optimal conditions for achieving the highest hydrogen production in the batch fermentation reactor were identified as a biochar concentration of 2% (w/v) and an immobilized cell size of 2 mm. The highest hydrogen yield, maximum hydrogen production rate, and lag time recorded were 0.69 mmol H2/g-COd, 0.02 mmol H2/g-COd.h, and 41.51 h, respectively. This research highlights the potential of cassava biochar technology for efficient biohydrogen production from food waste, contributing to renewable energy generation and sustainable waste management. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

In this paper, we have presented our experiment results including (a) use a slowly thermal spray process deposition an yttrium oxide (Y2O3) film with thickness of $200\ \mu\mathrm{m}$ on the aluminum alloy (AA6061). The image analysis showed that the porosity of Y2O3 film can be reduced to less than 2%. The further aerosol deposition can be used filling the pores and can reduce the porosity of the film to less than 0.5%. This low-porosity Y2O3 film will be able to meet the increasingly stringent requirements for surface coating protection of semiconductor vacuum chamber. (b) Compared the corrosion characterization in 3.5 wt. % NaCl solution between naked AA6061 and AA6061 with Y2O3 coating, a high corrosion reactivity ($\mathrm{I}_{\text{corr}}=10^{-3.3}\mathrm{A}/\text{cm}^{2}$) of naked AA6061 then AA6061 with Y2O3 coating ($\mathrm{I}_{\text{corr}}=10^{-5.8}\mathrm{A}/\text{cm}^{2}$). The corrosion reactivity of AA6061 with Y2O3 is reduced by 316 times to a naked AA6061. © 2024 IEEE.

Purpose: We investigated the volumetric changes in the components of the cholinergic pathway for patients with early mild cognitive impairment (EMCI) and those with late mild cognitive impairment (LMCI). The effect of patients’ apolipoprotein 4 (APOE-ε4) allele status on the structural changes were analyzed. Methods: Structural magnetic resonance imaging data were collected. Patients’ demographic information, plasma data, and validated global cognitive composite scores were included. Relevant features were extracted for constructing machine learning models to differentiate between EMCI (n = 312) and LMCI (n = 541) and predict patients’ neurocognitive function. The data were analyzed primarily through one-way analysis of variance and two-way analysis of covariance. Results: Considerable differences were observed in cholinergic structural changes between patients with EMCI and LMCI. Cholinergic atrophy was more prominent in the LMCI cohort than in the EMCI cohort (P < 0.05 family-wise error corrected). APOE-ε4 differentially affected cholinergic atrophy in the LMCI and EMCI cohorts. For LMCI cohort, APOE-ε4 carriers exhibited increased brain atrophy (left amygdala: P = 0.001;right amygdala: P = 0.006, and right Ch123, P = 0.032). EMCI and LCMI patients showed distinctive associations of gray matter volumes in cholinergic regions with executive (R² = 0.063 and 0.030 for EMCI and LMCI, respectively) and language (R² = 0.095 and 0.042 for EMCI and LMCI, respectively) function. Conclusions: Our data confirmed significant cholinergic atrophy differences between early and late stages of mild cognitive impairment. The impact of the APOE-ε4 allele on cholinergic atrophy varied between the LMCI and EMCI groups. © 2024, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
