Despite its prevalence, no definitive cure or therapy exists to halt its progression. PD symptoms majorly influence patients' everyday lives, so prompt identification is essential. Because the disease starts in the brain, we used electroencephalography (EEG) data in our research. We used the publicly accessible dataset ‘EEG: Simon Conflict in Parkinson's’, which consists of EEG recordings from 28 people with PD (ON–OFF medication) and 28 healthy people (CTL). Due to the sensitivity of EEG signals, noise components were removed using Independent Component Analysis (ICA) combined with the IClabel model. Cleaned signals were reconstructed and analyzed into five primary frequency bands: delta, theta, beta, alpha, and gamma with statistical features. Boosting methods from the ensemble algorithm family were applied to evaluate classification performance. The classification results are presented for two labels (healthy individuals and PD) and three (healthy individuals, PD in ON medication, and PD in OFF medication). The XGBoost model achieved the best classification performance, achieving high accuracy, sensitivity, and specificity within a reasonable computation time. The XGBoost model combined with ICA-ICLabel achieved 99.71% accuracy in PD-CTL classification and 91.35% accuracy in three-class classification (CTL-ON-OFF). © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"20 11","pages":"1862-1867"},"PeriodicalIF":1.1,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results confirmed that the current generated during two-fluid spraying exhibits positive polarity and that the droplet charge increases with droplet velocity. We further demonstrated that the charging of pure-water droplets can be controlled by installing an inductive charging element immediately downstream of the pure-water jet.

This method uses electroencephalography (EEG) to capture and understand neural processes relevant to taste perception, revealing how the brain stores sensory information. Understanding the neurological foundation of taste can help medical professionals diagnose and treat taste-related abnormalities caused by aging, trauma, or illnesses like COVID-19, Parkinson's disease, and Alzheimer's disease. This information may enhance product development in the industrial sector, particularly in the food and beverage industry, by tailoring goods to better meet customer preferences based on a deeper understanding of taste reactions. In scientific studies, deciphering brain signals associated with taste experiences is critical for neuroscience research, as it improves our understanding of how the brain processes information. The paper's originality stems from its multidisciplinary approach. It integrates information and methodologies from several domains, including neuroscience, biotechnology, and machine learning, to provide a novel way to decipher brain processes.

The field phase velocity data in the frequency domain, achieved after traditionally processing field seismic data in the time–distance domain, is inverted to build the true shear velocity model. We conducted two MASW surveys to understand the geological environment at M'Drak District, Dak Lak Province, Vietnam. The results can reveal three layers with a depth of up to 30 m. In the interest area, the first layer is interpreted as loose clay soil up to 20 m deep, with its shear velocity range from 200 to 500 m/s, which can be responsible for landslides. Being considered as an extremely weathered fault rock, the second layer can have a thickness and shear wave velocity of 3–5 m and 500–800 m/s, respectively. The third one is analyzed as moderately weathered fault rock, firm, and stable thanks to its high shear wave velocity values. The MASW method helps to detect the low velocity layer that may relate to a weak soil zone. This near-surface loose clay soil in the survey area needs reinforcement before construction because of safety. Comprehensive foundation preparation work is necessary to prevent future landslides and ground subsidence. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"20 11","pages":"1896-1900"},"PeriodicalIF":1.1,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With advancements in healthcare and a growing focus on enhancing quality of life, traditional invasive glucose monitoring methods are increasingly viewed as outdated and uncomfortable. Saliva, as a non-invasive and easily accessible biofluid, has shown a strong correlation between glucose levels in saliva and blood, especially in diabetes patients, presenting a promising alternative for glucose monitoring. Impedance analysis, a technique known for its non-invasive, label-free, real-time, and cost-effective nature, aligns perfectly with the demand for more patient-friendly approaches. This study investigates the feasibility of applying impedance analysis to identify and quantify glucose levels in saliva samples. The findings demonstrate that impedance measurements at 1.19 MHz effectively distinguish between saliva samples with and without glucose, measurements at 480 Hz and 10.1 kHz can effectively identify the glucose sample with concentration as low as 2 mg/dl, while measurements at 85 kHz exhibit a strong correlation (R2 = 0.9959) between impedance values and glucose concentration with a LOD of 1.5 mg/dl. These results suggest that impedance analysis has significant potential as a comfortable, accessible, and reliable method for glucose monitoring, paving the way for improved diabetes management and patient care. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"20 11","pages":"1901-1906"},"PeriodicalIF":1.1,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Petri net is a discrete graphical modeling tool which can visualize the relationships and flows between the manufacturing processes and resource allocations. The flexible adaptation and extension capabilities of Petri net can accurately describe the resource flows in resource allocation processes. At the same time, the combination of Petri nets and bisimulation methods allows the construction of simulation processes that require qualitative allocation of flexible resources, which ensures that resource flows are accurately allocated into specific manufacturing cells. This paper aims to model how the four-color theorem and the Petri net based bisimulation approach can be fully combined to simulate a subnet composed of manufacturing units where flexible resources need to be allocated in a targeted and private manner. In this paper, we apply the four-color theorem as a theory tool to combine with Petri net based bisimulation to ensure resource independences and privacies among manufacturing units in the flexible resource allocation. The Petri net modeling with the four-color theorem is proposed, and definitions of Petri net based bisimulation with non-interference combining with the four-color theorem are given. We also give the mathematical proofs and validations for BNDPN with the Four-Color Theorem. Furthermore, we evaluate the performance of the strategy of BNDPN with the Four-Color Theorem in flexible resource allocation and compare the evaluation results with existing works. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"20 11","pages":"1717-1729"},"PeriodicalIF":1.1,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
