Spatio-temporal evolution of the L -> I -> H transition [PDF]

, 2012
International audienceWe investigate the dynamics of the low(L) → high(H) transition using a time-dependent, one dimensional (in radius) model which self-consistently describes the time evolution of zonal flows (ZFs), mean flows (MFs ...

Locality effects on bifurcation paradigm of L-H transition in tokamak plasmas [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2015
The locality effects on bifurcation paradigm of L-H transition phenomenon in magnetic confinement plasmas are investigated. One dimensional thermal transport equation with both neoclassical and anomalous transports effects included is considered, where

L-H transition studies on spherical tokamaks [PDF]

, 2023
While the higher fusion power achieved in high confinement (H-)mode make it a desirable regime for tokamak devices, the transition from low confinement (L-)mode to H-mode is a complex, multi-faceted process whose dynamics are still not fully understood ...

Effects of Flow Velocity on the Growth and Survival of Haliotis discus hannai Larvae in the Recirculating Upflow System From the Point of Energy Metabolism

Frontiers in Marine Science, 2021
For the abalone Haliotis discus hannai, attachment and metamorphosis are crucial stages in the transition from planktonic to benthic life. Increasing the larval metamorphosis rate by artificially controlling the external environment and simulating ...

Understanding the L-H isotope effect at the DIII-D tokamak and advancements in synthetic turbulence diagnostics

Nuclear Fusion
It is determined that while heat flux differences between hydrogen and deuterium isotope experiments result from natural differences in carbon impurity content at DIII-D, it is not the origin of the low to high confinement mode (L-H) transition isotope ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Neural network identification of the weakly coherent mode in I-mode discharge on EAST

Nuclear Fusion, 2023
The improved energy confinement mode (I-mode) is widely considered as an important operation regime for ITER. I-mode implementation depends on the specified basic plasma parameters and certain operation conditions, which are discovered by statistical ...

The feasibility of the L-H transition for a purely electron-heated EU-DEMO tokamak

Nuclear Fusion
We study numerically the feasibility of achieving the L-H transition in the current EU-DEMO tokamak baseline using uniquely direct electron heating. The ASTRA code coupled to the TGLF turbulent transport model is used to predict steady-state kinetic ...
