FEM-based plasma equilibrium reconstruction for transient and off-normal phases in KSTAR

Jeongwon Lee, Jayhyun Kim, J.G. Bak, S.H. Hahn et autres

In this study, we developed a finite element method (FEM)-based equilibrium reconstruction code for the KSTAR tokamak to analyze plasma behavior during highly transient phases, including early startup, pre-disruption, and vertical displacement events (VDEs), where conventional equilibrium fitting (EFIT) reconstructions often fail …

Validation of integrated modeling of KSTAR plasmas with carbon divertor using JINTRAC and prediction for tungsten divertor

Beomsu Kim, Sun Hee Kim, Florian Koechl, F. J. Casson et autres

Abstract The JINTRAC integrated modeling suite has been adapted for the KSTAR tokamak, with its primary goal being the establishment of a core-edge integrated modeling framework for predictive analysis of KSTAR plasmas. This framework was validated by benchmarking JINTRAC’s physics modules against …

On FIRE mode in KSTAR

Yong-Su Na, Sangjin Park, Hyunsun Han, J D Lee et autres

Abstract We report on the status of Fast Ion Regulated Enhancement (FIRE) mode experiments in the Korea Superconducting Tokamak Advanced Research. This regime is being developed for high-performance, steady-state operation which features a stationary ion internal transport barrier, enabling a central ion …

ER protein CLCC1 promotes nuclear envelope fusion in herpesviral and host processes

Bing Dai, Adrian W. Sperl, Lucas Polack, Isabel Mejia et autres

Herpesvirales are an ancient viral order that causes lifelong infections in species from mollusks to humans. They export their capsids from the nucleus to the cytoplasm by a noncanonical nuclear egress route that involves capsid budding at the inner nuclear membrane followed …

Development of a data-driven neural network model for electron thermal transport in NSTX

Chanyoung Lee, G. J. Choi, S. Kaye, B.P. LeBlanc et autres

Abstract A data-driven electron thermal transport neural network (ETT-NN) model, trained on TRANSP interpretative analysis results of National Spherical Torus Experiment (NSTX), was developed to enable faster and more accurate ETT computation for spherical tokamaks (STs). The model incorporates both convolutional NNs …

CLCC1 promotes membrane fusion during herpesvirus nuclear egress

Bing Dai, Lucas Polack, Adrian W. Sperl, Haley Dame et autres

are an ancient viral order that infects species from mollusks to humans for life. During infection, these viruses translocate their large capsids from the nucleus to the cytoplasm independently from the canonical route through the nuclear pore. Instead, capsids dock at the …

A control oriented strategy of disruption prediction to avoid the configuration collapse of tokamak reactors

A. Murari, Riccardo Rossi, T. Craciunescu, J. Vega et autres

The objective of thermonuclear fusion consists of producing electricity from the coalescence of light nuclei in high temperature plasmas. The most promising route to fusion envisages the confinement of such plasmas with magnetic fields, whose most studied configuration is the tokamak. Disruptions …

Cell Surface Modification-Mediated Primary Intestinal Epithelial Cell Culture Platforms for Assessing Host–Microbiota Interactions

Panida Sittipo, Laurensia Danis Anggradita, Hyunbum Kim, Chanyoung Lee et autres

Background: Intestinal epithelial cells (IECs) play a crucial role in regulating the symbiotic relationship between the host and the gut microbiota, thereby allowing them to modulate barrier function, mucus production, and aberrant inflammation. Despite their importance, establishing an effective ex vivo culture …
