CONSTRUCTIVE RELATIONS IN ELECTRIC MACHINES OF MECHATRONIC SYSTEMS WITH CONCENTRATED STATOR WINDINGS AND A TOOTHE NON-WINDING ROTOR
Authors: Korchagin O. 
Published: April 2024

The issues of substantiation and selection of basic design relationships of induction machines with single-tooth windings, which can be part of newly developed mechatronic systems, are considered.
The relationships substantiated in this work can be applied in the development of new mechatronic systems, especially when the task of developing mechatronic modules for specified dimensions is often encountered in practice, which requires the development of both motors, new angle and speed sensors. In addition, this task becomes more urgent when setting harsh operating conditions, such as low and high temperatures, shocks, vibrations, and operation in submersible servos filled with oil. All this makes it difficult or impossible to use a number of other non-electromechanical sensors, such as optical, discrete Hall sensors, which further narrows the range of purchased products for embedding in the specified dimensions of the module. The considered ratios allows to implement sensors not only for different product dimensions, but also to take into account the purpose, accuracy requirements, and design meters with different electrical reduction, with different number of phases. An additional advantage of developing sensors according to these ratios is manufacturability, simplicity and speed of development and the ability to quickly launch into production.
In addition, the derived ratios make it possible to design an angle sensors, speed sensors, as well as electric motors and generators, which may be in demand in a number of special cases, for example, if it is necessary to minimize the moment of inertia of the motor rotor and to build high-speed machines.

Authors: Afsar Anum , Yasmin Rifat , Hussain Huma , Shah Syed Asim Ali , Abidi Syeda Turab Fatima , Ul Qadir Aziz 
Published: April 2024

Objective: Neutrophil-to-lymphocyte and lymphocyte-to-C-reactive protein ratios are important prognostic indicators for disease severity measurement among coronavirus patients. To predict the disease severity, CURB-65 scores, and outcome after 14 days of admission using two proxy biomarkers (neutrophil lymphocyte and lymphocyte C-reactive protein ratios) in COVID-19 patients.
Methodology: A prospective study was done at the Department of Medicine, Pakistan Ordinance Factory (POF) hospital, Wah Cantt, Pakistan, from April to August 2022. A total of 123 coronavirus patients were included. Patients with clinical manifestations, decreased lymphocyte and leukocyte counts, imaging characteristics of pneumonia, etiological evidence of a positive real time PCR test of blood or respiratory samples, and viral gene sequencing similar to known COVID-19 were measured. Patients underwent laboratory measurements and imaging analysis for biomarker indications. The analysis of the data was conducted using SPSS version 23.
Results: The patients mean age was 53.83±16.2 years. Among 123 COVID-19 patients, 80 (65%) were males and 43 (35%) were females. It was found to have high NLR and low LCR in severe disease (p = 0.05, p = 0.01). NLR and LCR showed 11% variance for disease severity (β = 0.143, p = 0.00, and β = -0.293, p = 0.01). NLR and LCR showed 29% variance for CURB 65 scores (β = 0.48, p = 0.634, and β = -0.159, p = 0.08). NLR and LCR showed 22% variance for outcome after 14 days of admission (β=-0.53, p=0.562, & β=-0.132, p=0.149).
Conclusion: Neutrophil to lymphocyte and lymphocyte to C-reactive protein ratios are effective prognostic biomarkers for measuring the severity of disease in COVID-19 patients. High neutrophil-to-lymphocyte and low lymphocyte-to-C-reactive protein ratios significantly predict disease severity.
First-principles study on edge–edge interactions of bilayer zigzag SiC nanoribbons
Authors: Sharifi Jawahir Ali , Sun Rongyao , Nakamura Jun 
Published: April 2024

Abstract
We have identified a complex interplay of van der Waals, coulombic, and direct edge-to-edge covalent interactions as key factors in determining the stability of bilayer zigzag SiC nanoribbons (ZSiCNRs). The Si–Si edge of the homo-AA-stacked ZSiCNR displays a unique bond angle, indicative of sp
3-like covalent bonds. In contrast, the C–C edge shows a flat structure, suggesting a formation of the pseudo-chemical bonding between p

z
orbitals at the edge like bilayer graphene NRs. The homo-AA-stacked ZSiCNR is nonmagnetic and metallic, although the monolayer ZSiCNR exhibits magnetic properties due to spin-polarized p

z
orbitals localized at the edge Si and C atoms. In contrast, the hetero-AA-stacked ZSiCNR is more stable than the homo one and is indicative of semiconductor properties with a finite band gap, since the topology of the edge states originating from p

z
orbitals is no longer preserved.
Fabry–Perot interference temperature sensor integrated high-power-laser optical fiber probe for laser ablation
Authors: Fukano Hideki , Ooshima Kazuma 
Published: April 2024

Abstract
In this study, an optical fiber probe with an extremely short integrated temperature sensor for high-power laser ablation was proposed and successfully fabricated. Both optical mode and wavelength multiplication were performed simultaneously using a double-clad fiber with a wavelength-division multiplication technique. The wavelength shift with temperature showed a linear relationship with a sensitivity of 10 pm/°C. High-power laser irradiation of 1000 mW or more using multimode transmission and fine temperature monitoring using single-mode transmission were performed simultaneously with a system response time of a few seconds. The laser wavelength selection and power variation can increase the variability of the heating region required for medical applications.
Quantitative analysis of optical emission spectroscopy for plasma process monitoring
Authors: Akatsuka Hiroshi 
Published: April 2024

Abstract
In the field of plasma materials processing, various plasma parameters should be evaluated quantitatively and precisely to control the plasma process adequately, particularly with non-invasive methods, one of which is optical emission spectroscopy (OES) measurement. It has sufficient scientific feasibility to derive the electron density N
e, electron temperature T
e, and the electron energy distribution function (EEDF) even for various processing plasmas in a state of non-equilibrium. In this review, previous studies are reviewed to measure the N
e, T
e, and EEDF values of argon plasma with low-electron temperature (T
e ≃ 1–10 eV) under not only low-pressure conditions but also atmospheric-pressure discharge using the OES measurement. First, to diagnose low-pressure discharge argon plasmas, we explain the basics and applications of the “collisional radiative model”, which models the population kinetics of the excited states in plasma at the elementary process level in non-equilibrium plasma. Methods for analyzing the plasma parameters are shown from the actual measurement results of emission spectra, including machine learning analysis of the excited-state populations. Next, the research results of the method to measure N
e, T
e, and EEDF are introduced for the measurement of atmospheric-pressure non-equilibrium plasmas using OES measurement of continuum emission, which also includes methods based on machine learning and data-scientific methods for the analysis of the OES data observed as bremsstrahlung of free electrons scattered against neutral molecules.
Scanning strategy-dependent etching rate in the formation of through-via holes by femtosecond laser-assisted etching
Authors: Matsuda Shogo , Matsuo Shigeki 
Published: April 2024

Abstract
In this study, we used femtosecond laser-assisted etching (FLAE) to drill through glass vias (TGVs) in 0.3 mm thick non-alkali glass substrates. In FLAE, the focus of the femtosecond laser pulses is scanned to modify the material along a preprogrammed pattern, and the modified region is preferentially removed by chemical etching. We found that the scanning strategy affected the etching rate along the laser-modified lines. Among four types of scanning strategies tested, the strategy 〈du〉—that is, scanning in a downward direction followed by an upward direction—obtained the highest etching rate. In this case, the etching rate along the laser-modified line was approximately 10 times larger than that of the unmodified region.

Cost-Effectiveness of an Intensive Upper Limb Rehabilitation Therapy for Children With Unilateral Cerebral Palsy: An Economic Evaluation of a Randomized Controlled Trial
Authors: David Michael C. , Higashi Hideki 
Published: April 2024

Background: Unilateral cerebral palsy is a major cause of childhood disability and a substantial economic burden. Intensive group-based therapy, consisting of hybrid constraint-induced movement and bimanual therapies, has been shown to be effective in improving specific quality-of-life domains in children with this disability. Our objective in this study was to assess if this intervention was cost-effective compared with standard care. Methods: An open-label, parallel, randomized controlled trial with an embedded economic evaluation of the intervention was conducted. A total of 47 children were randomized to either the intervention group (n = 27) or the standard care (n = 20) group. The effectiveness of the intervention was assessed using the Cerebral Palsy Quality of Life (Child) questionnaire across several domains. Nonparametric bootstrapping was used to quantify uncertainty intervals (UIs) for incremental cost-effectiveness ratios. Results: The incremental cost-effectiveness ratios for the intervention were $273 (95% UI: $107 to $945) for Pain and Impact of Disability, $1071 (95% UI: -$5718 to $4606) for Family Health and $1732 (95% UI: -$6448 to $8775) for Access to Services. For the 4 remaining domains, the intervention was dominated by standard care. At a willingness-to-pay threshold of $1000, only for the Pain and Impact of Disability domain was the intervention likely to have a probability of being cost-effective exceeding 0.75. Conclusions: Other than the Pain and Impact of Disability domain, there was insufficient evidence demonstrating the intervention to be cost-effective over a 13-week time horizon.
