Specifically, studies on microplastics (MPs) transport affected by the complex hydrodynamic conditions in the Mekong estuary are scarce. The study aims to understand the movement of MPs from the Hau estuaries (a branch of the Mekong River) to the East Sea during the Northeast and Southwest Monsoons (January 2024 and July 2023, respectively). Using the OpenDrift trajectory model with the DNORA dynamic downscaling tool, findings reveal that the monsoon climate significantly influences MP transport. Wave action primarily affects MPs dispersion near estuaries and coastal zones, while current dynamics are key to MP movement to the East Sea. A one-month simulation indicates that MPs accumulate in various locations, including the Ca Mau coast, Hon Khoai Island, Phu Quy Island, Do Lon Island, and the Truong Sa Archipelago, with notable concentrations along the Malaysian coast. Additionally, neighboring countries like Thailand and the Philippines face a substantial risk of MPs pollution from the Hau estuaries. © 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":"1914-1920"},"PeriodicalIF":1.1,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196942","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}

Between February and March, the region experienced three periods of increased saltwater intrusion, primarily driven by the El Niño phenomenon, which resulted in a striking lack of rainfall (60%–95% below normal levels). Extended sunny days led to considerable evaporation from fields, canals, rivers, and lakes. Concurrently, reduced upstream water flow into the Delta and heightened spring tide levels pushed saltwater deeper into rice fields, severely impacting local livelihoods and agriculture. To address this issue, the study aims to predict evapotranspiration and water demand using the CROPWAT 8.0 model in combination with simulating the growth and development of rice crops in An Giang province by utilizing the ORYZA model. This research will focus on the three main rice growing seasons: Winter–Spring, Summer-Autumn, and Autumn-Winter, utilizing a rice variety with a growth duration of 95–100 days. Forecasts for 2024 will rely on drought data from 2019, projecting continuous high temperatures (0.5 °C above 2019 levels) and no rainfall from January to May in 2024.

This study focuses on optimizing a GHz-range thin-film magnetic sensor by incorporating a slit pattern in the magnetic layer, which improves impedance matching and current distribution. Amorphous CoNbZr thin-film sensors with slit widths ranging from 0 μm (no slit) to 50 μm were fabricated. Among these, the 10 μm slit design exhibited the best impedance matching and magnetic field sensitivity. Additionally, a carrier suppression circuit was implemented to reduce phase noise, resulting in improved sensitivity, achieving a minimum detectable field of 1.41 × 10−11 T/√Hz. The sensor was employed for precise near-field measurements in wireless power transfer (WPT) systems, where it outperformed conventional loop antennas. Experimental results demonstrated superior sensitivity and enhanced spatial resolution, particularly near the ferromagnetic resonance under specific DC bias and carrier frequency conditions.

In liquid biopsy, there are various markers used to detect cancer, such as small nucleic acids and circulating tumor cells (CTCs), along with extracellular vesicles (EVs). Detecting CTCs in patients' blood is crucial, as it provides important information about proteins and sugar chains on their membranes and the nucleic acids inside. However, detecting CTCs is difficult because they are rare compared to the millions of blood cells present. To address this challenge, we propose a new method using ion-sensitive field-effect transistors (ISFETs) combined with chemical signal amplification through enzyme reactions to detect cell membrane proteins. We tested this method using breast cancer cell lines as models for CTCs and successfully detected human epidermal growth factor receptors (HER2 and EGFR) on their membranes using cell-based transistors. Initially, we demonstrated the detection of HER2 through an enzyme reaction using the BT474 breast cancer cell line. Then, we compared EGFR expression among four types of breast cancer cell lines using the cell-based transistors, and the results were consistent with fluorescence detection using fluorescence-activated cell sorting (FACS). These cell-based transistors offer advantages in terms of miniaturization and analyzing target molecules on cell and EV membranes in parallel. Their small size and cost-effectiveness for cancer testing could make them a reality in future liquid biopsy methods. In this review, we present our recent advancements in cell-based transistors. We will then explore the future prospects of cell-based transistors in liquid biopsy. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"20 10","pages":"1526-1533"},"PeriodicalIF":1.1,"publicationDate":"2025-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/tee.70124","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To understand the wind and ice response characteristics of the terminal tower-line system in a wind farm. A spatial finite element model of the terminal tower-line system of a 35 kV wind farm was established, and the harmonic superposition method was employed to simulate the fluctuating wind load time history of the system. By superimposing static wind loads, the characteristics of the wind-induced vibration response and the dynamic stability of the ice-covered tower-line system under different wind direction angles were analyzed. The results indicated that, compared to a single tower structure, the tower-line coupling effect has a more significant impact on the wind-induced vibration response of the terminal tower-line system. The most unfavorable wind direction is perpendicular to the conductor arrangement, and the maximum stress on the tower occurs on the windward side where the conductor is attached. The tension of the conductor has the greatest impact on the terminal tower, and this effect is further amplified by conductor icing and galloping. Finally, a method is proposed to assess the dynamic stability of terminal tower-line systems based on yield criteria. © 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":"1687-1694"},"PeriodicalIF":1.1,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197341","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}
