Stability of Tripartite Entangled State in Spin Trimer Coupled to a Magnetic Ion

C.-I. Kim, C.-H. Jong, T.S. So, C.-S. Yun et autres

Abstract A model of a spin-1/2 trimer coupled to a magnetic ion with spins ranging from 1/2 to 5/2 is introduced. We numerically calculate tripartite negativity of spin trimer. Numerical results show that the tripartite negativity has a nonzero plateau regardless of …

Reinforcement learning optimization of a 6 Li magneto-optical trap: DDPG versus SAC

Deok Young Lee, jaeha shin, Jae-yoon Choi

We report an experimental implementation of deep reinforcement learning (RL) for optimizing the loading stage of a 6 Li magneto-optical trap (MOT) in a high-dimensional continuous control space. An off-policy actor-critic agent observes in-situ fluorescence images at 111 ms intervals and updates …

Atypical MDM2 p53 Regulation and Chemosensitivity Induced by Proximal PAS Deletion

Minseo Kim, Celine Yoon, Jaewan Jun, Yumin Lee et autres

Abstract This study proposes a novel therapeutic strategy to suppress cancer growth by modulating the MDM2-p53 axis via Alternative Polyadenylation (APA). MDM2 normally promotes tumorigenesis by ubiquitinating and degrading the tumor suppressor p53. In cancer cells, preferential use of proximal polyadenylation signals …

Comparative effectiveness of pioglitazone and sitagliptin added to metformin and sulfonylurea in patients with type 2 diabetes

Tae Hyeon Kim, Yerin Hwang, Selin Woo, Kyeongmin Lee et autres

Dipeptidyl peptidase-4 inhibitors and thiazolidinediones are commonly used as add-ons in type 2 diabetes mellitus (T2DM) treatment, but comparative data are limited. This study emulated a target trial to compare sitagliptin and pioglitazone in patients on metformin and sulfonylurea, focusing on changes …

Crucial Role of Partial Fluorination in Modulation of Thermal Conductivity of Graphene Nanoribbon: Non-Equilibrium Molecular Dynamics Simulations

Yong-Chol Ju, Chol-Gun Choe, Nam-Chol Ri

Abstract Molecular dynamics simulations have been performed to investigate the modulation of the thermal conductivity of graphene nanoribbon as function of partial fluorographene nanoroad. Thermal conductivities of the hybrid systems keep stable value below 25 ps of simulation time. All hybrid graphene …

Confinement considerations for CRISPR toxin-antidote gene drive systems

Ziqian Xu, Yuna I Cho, Xinyue Zhang, Jackson Champer

Abstract Gene drives are potentially powerful tools, able to spread throughout target populations. They could be used to modify or suppress disease vectors, invasive species, and agricultural pests. Yet, in many scenarios, confinement of the drive to only a target population is …

Effective Micropropagation of Ailanthus altissima ‘Hongyechun’, an Ornamental and Economically-Important Tree of Simaroubaceae

K. W. Kim, H. G. Hong, U. H. Ryu, J. H. Kim et autres

Abstract This research developed an effective protocol for micropropagation of Ailanthus altissima ‘Hongyechun’. Axillary shoots from dormant twigs dipped in water were sterilized with 70% ethanol for 15 s and with 0.1% HgCl2 solution for 7 min, resulting in the survival rate …
