Quasi-10 d wave activity in the southern high-latitude mesosphere and lower thermosphere (MLT) region and its relation to large-scale instability and gravity wave drag
Autor: W. Lee, I.-S. Song, B.-G. Song, Y. H. Kim
Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 3559-3575 (2024)
Seasonal variation in westward-propagating quasi-10 d waves (Q10DWs) in the mesosphere and lower thermosphere of the Southern Hemisphere (SH) high-latitude regions is investigated using meteor radar (MR) observations for the period of 2012–2016 and

Ultrafast Martensitic Phase Transition Driven by Intense Terahertz Pulses
Autor: B. Q. Song, X. Yang, C. Sundahl, J.-H. Kang, M. Mootz, Y. Yao, I. E. Perakis, L. Luo, C. B. Eom, J. Wang
Publikováno v: Ultrafast Science, Vol 3 (2023)
We report on an ultrafast nonequilibrium phase transition with a strikingly long-lived martensitic anomaly driven by above-threshold single-cycle terahertz pulses with a peak field of more than 1 MV/cm. A nonthermal, terahertz-induced depletion of lo

Propagation of gravity waves and its effects on pseudomomentum flux in a sudden stratospheric warming event
Autor: I.-S. Song, C. Lee, H.-Y. Chun, J.-H. Kim, G. Jee, B.-G. Song, J. T. Bacmeister
Publikováno v: Atmospheric Chemistry and Physics, Vol 20, Pp 7617-7644 (2020)
Effects of realistic propagation of gravity waves (GWs) on distribution of GW pseudomomentum fluxes are explored using a global ray-tracing model for the 2009 sudden stratospheric warming (SSW) event. Four-dimensional (4D; x–z and t) and two-dimens

Magnetostructural transitions in V-doped MnCoGe compounds
Autor: J. H. Shi, H. G. Zhang, Imam Hidayah, B. T. Song, H. Yao, M. Yue, Z. Altounian
Publikováno v: AIP Advances, Vol 10, Iss 2, Pp 025325-025325-6 (2020)
MnCoGe1-xVx (x = 0.005, 0.01, 0.015, 0.02, 0.03, and 0.04) compounds were synthesized and investigated in view of the effect of transition metals on main-group-element sites to the magnetostructural transition. A small amount of V doping results in a

Estimating Incumbency Effects Using Regression Discontinuity Design
Autor: B. K. Song
Publikováno v: Research & Politics, Vol 5 (2018)
In recent years, research on the incumbency effect using a regression discontinuity design has flourished. Although the regression discontinuity design has allowed scholars to examine the incumbency effect in various electoral settings, previous stud

Effects of different cryoprotectants on the cryopreservation of cattle testicular tissue
Autor: S. Hu, Q.-C. Zhu, C. Han, X.-G. Zhang, B. Y. Song, D.-Q. Xie, S.-Y. Wei, J.-H. Hu
Publikováno v: Archives Animal Breeding, Vol 58, Iss 2, Pp 433-439 (2015)
Cryopreservation of testicular tissue is a new option in fertility preservation for prepubertal male animals. The purpose of this study was to explore the effects of different cryoprotectant agents (CPAs) at various concentrations on testes after the
