Research on commutation failure of Jinsu DC transmission project caused by a complex AC fault
The Journal of Engineering, 2019 Commutation failure is an important factor on safe and stable operation of the receiving-end power grid for high voltage direct current (HVDC) project. A commutation failure event in Jinsu DC transmission project caused by a complex AC failure was taken ...

The Effect of Voluntary Staying at Home on Japanese Female Suicide During the COVID‐19 Pandemic
Health Economics, EarlyView.ABSTRACT In Japan, female suicide increased during the COVID‐19 pandemic. This study evaluated how pandemic‐related home confinement affected female suicide. We employed a shift‐share instrumental variable design to assess whether differential exposure to the pandemic caused changes in suicide incidence.

Disparities in Proton Radiation Utilization for HPV‐Associated Oropharyngeal Cancer Following TORS
Head &Neck, EarlyView.ABSTRACT Introduction Racial, socioeconomic, and geographic disparities in receipt of proton radiation have been reported. Whether disparities exist for oropharyngeal squamous cell carcinoma (OPSCC) is not well studied. Methods Patients with HPV‐associated OPSCC treated with transoral robotic surgery (TORS) and adjuvant radiation from 2016 to 2023 were

Feasibility of applying inductive filtering technology to the HVDC transmission system
The Journal of Engineering, 2018 This study explores the feasibility of applying inductive filtering technology to high-voltage direct-current (HVDC) transmission system since only filtering in the net side may lead to a lot of harmonics in the converter transformer. Basic principles of

Land Use Policy and Racial Segregation
International Studies of Economics, EarlyView.ABSTRACT Land use policies, though seemingly race‐neutral, can inadvertently contribute to racial segregation. Our study focuses on examining the impact of minimum lot size regulations on the likelihood of ethnic minorities integrating into a community, which reveals compelling evidence suggesting that black households exhibit a preference for smaller ...

GELFOND-LEONTYEV GENERAL DIFFERETIATION OPERATORS AND BRENKE POLYNOMIALS
Advanced Engineering Research, 2010 Natural connection between Gelfond-Leontyev generalized derivation operators (GDO) and Brenke polynomials is established. Operator extension criterion commuting with GDO up to continuous H(G) space is derived.

Journal of Consumer Psychology, EarlyView.Abstract Although consumers who engage in the same sustainable behaviors objectively have the same environmental impact, this research finds that people's perceptions of that impact are subjective and systematically shaped by political ideology. Seven studies demonstrate that conservatives tend to perceive their sustainable actions to have less of a ...

The HVDC commutation failure mechanism impacted by harmonics and its suppression method
Frontiers in Energy ResearchHarmonics are an important cause of voltage distortion, and voltage reduction and voltage distortion are the main causes of commutation failure. But most of the current research studies on commutation failure are based on the drop in fundamental voltage ...
