Ionizing terahertz waves with 260 MV/cm from scalable optical rectification
Autor: Hyeongmun Kim, Chul Kang, Dogeun Jang, Yulan Roh, Sang Hwa Lee, Joong Wook Lee, Jae Hee Sung, Seong Ku Lee, Ki-Yong Kim
Publikováno v: Light: Science & Applications, Vol 13, Iss 1, Pp 1-13 (2024)
Abstract Terahertz (THz) waves, known as non-ionizing radiation owing to their low photon energies, can actually ionize atoms and molecules when a sufficiently large number of THz photons are concentrated in time and space. Here, we demonstrate the g

Investigation of terahertz radiation generation from laser-wakefield acceleration
Autor: Mohammad Rezaei-Pandari, Mohammad Mirzaie, Calin Ioan Hojbota, Ali Reza Niknam, Reza Massudi, Ki-Yong Kim, Chang Hee Nam
Publikováno v: AIP Advances, Vol 14, Iss 2, Pp 025347-025347-8 (2024)
We investigate the generation of terahertz (THz) radiation from laser-wakefield acceleration (LWFA) in a helium gas jet. We consider a three-dimensional setup incorporating a realistic gas density distribution and use particle-in-cell simulations to

Multi-millijoule terahertz emission from laser-wakefield-accelerated electrons
Autor: Taegyu Pak, Mohammad Rezaei-Pandari, Sang Beom Kim, Geonwoo Lee, Dae Hee Wi, Calin Ioan Hojbota, Mohammad Mirzaie, Hyeongmun Kim, Jae Hee Sung, Seong Ku Lee, Chul Kang, Ki-Yong Kim
Publikováno v: Light: Science & Applications, Vol 12, Iss 1, Pp 1-11 (2023)
The electrons, accelerated by the laser ponderomotive force and subsequent plasma wakefields, radiate broadband emission continuously along the laser propagation direction, resulting in multi-mJ THz radiation in the far field.

Functional improvement of bilateral frozen shoulder by unilateral intra-articular corticosteroid injection: a retrospective study
Autor: Minchul Kim, Ki-Yong Kim, Yool-Gang Huh, Sang Hyeok Ma, Kil-Yong Jeong, Seung-Hyun Yoon
Publikováno v: Journal of International Medical Research, Vol 49 (2021)
Objective Bilateral frozen shoulder (FS) is often treated with intra-articular corticosteroid injection (IACI). No studies have been performed to establish whether IACI must be administered in both shoulders or in only one shoulder to improve functio

Investigation of Solanum carolinense Dominance and Phytotoxic Effect in Festuca arundinacea with Special Reference to Allelochemical Identification, Analysis of Phytohormones and Antioxidant Mechanisms
Autor: Lee-Rang Kim, Arjun Adhikari, Yosep Kang, Ho-Jun Gam, Sang-Mo Kang, Ki-Yong Kim, In-Jung Lee
Publikováno v: Agronomy, Vol 12, Iss 8, p 1954 (2022)
Exposure to invasive weeds in pasturelands may result in significant losses and toxicity in forage crops. These species may also contain a compound that may be toxic as well as beneficial depending upon the effect induced. The Ministry of Environment

Phosphate-Solubilizing Enterobacter ludwigii AFFR02 and Bacillus megaterium Mj1212 Rescues Alfalfa’s Growth under Post-Drought Stress
Autor: Sang-Mo Kang, Muhammad-Aaqil Khan, Muhammad Hamayun, Lee-Rang Kim, Eun-Hae Kwon, Yo-Sep Kang, Ki-Yong Kim, Jae-Jeong Park, In-Jung Lee
Publikováno v: Agriculture, Vol 11, Iss 6, p 485 (2021)
Drought stress is a prevalent environmental stress that adversely affects agricultural industries worldwide. In this study, bacterial isolates, AFFR02 and Mj1212, showed tolerance to polyethylene glycol-induced (PEG) drought stress (approximately 15%

Publikováno v: Asian-Australasian Journal of Animal Sciences, Vol 25, Iss 6, Pp 818-823 (2012)
Tall fescue (Festuca arundinacea Schreb.) is an important cool season forage plant that is not well suited to extreme heat, salts, or heavy metals. To develop transgenic tall fescue plants with enhanced tolerance to abiotic stress, we introduced an a
