Effects of alcohols and dissolved gases on sonochemical generation of hydrogen in a 300 kHz sonoreactor

Autor: Jongbok Choi, Seokho Yoon, Younggyu Son

Publikováno v: Ultrasonics Sonochemistry, Vol 101, Iss , Pp 106660- (2023)

The sonochemical generation of hydrogen (H2) was investigated using various water/alcohol solutions under argon (Ar) 100 % in a 300 kHz sonoreactor. Five types of alcohols–methanol, ethanol, isopropanol, n-propanol, and n-butanol–were used at var

Order statistics and recursive updating with aging factor for cooperative cognitive radio networks under SSDF attacks

Autor: Seungwon Lee, Yalei Zhang, Seokho Yoon, Iickho Song

Publikováno v: ICT Express, Vol 6, Iss 1, Pp 3-6 (2020)

For detecting the presence of the primary user under malicious attacks in cooperative cognitive radio networks, we propose a detection scheme based on the order statistics and recursive updating algorithm with aging factor. The aging factor not only

Case Report: Acute Kidney Injury Due to Chronic Milk-Alkali Syndrome in a Patient With Colon Cancer

Autor: Hyo Jin Lee, Seokho Yoon, Bong-Hoi Choi, Seunghye Lee, Sehyun Jung, Ha Nee Jang, Se-Ho Chang, Hyun-Jung Kim

Publikováno v: Frontiers in Medicine, Vol 9 (2022)

BackgroundCommon causes of hypercalcemia include primary hyperparathyroidism and paraneoplastic syndrome of malignancy. Because of this, physicians can easily miss extrinsic causes of hypercalcemia such as milk-alkali syndrome in patients with cancer

Neurocomputational mechanism of controllability inference under a multi-agent setting

Autor: Jaejoong Kim, Sang Wan Lee, Seokho Yoon, Haeorm Park, Bumseok Jeong

Publikováno v: PLoS Computational Biology, Vol 17, Iss 11 (2021)

Controllability perception significantly influences motivated behavior and emotion and requires an estimation of one’s influence on an environment. Previous studies have shown that an agent can infer controllability by observing contingency between

Unambiguous Tracking Technique Based on Sub-Carrier Pulse Grouping for TMBOC-Modulated Signals in GPS

Autor: Keunhong Chae, Seungsoo Yoo, Sun Yong Kim, Gyu-In Jee, Dong-Jin Yeom, Seokho Yoon

Publikováno v: IEEE Access, Vol 4, Pp 7785-7794 (2016)

Based on grouping the pulses that compose the sub-carrier of the time-multiplexed binary offset carrier (TMBOC), we present an unambiguous correlation function that has no side-peaks causing the ambiguity in the TMBOC signal tracking, and also, that
