Gyrokinetic simulation of eigenmode GAM in EAST H-mode plasma

Nuclear Fusion
Gyrokinetic simulations based on the Gyrokinetic Toroidal Code are conducted to investigate the geodesic acoustic mode (GAM) physics in the pedestal of EAST H-mode discharge $\#$ 74036 (Zhou et al 2018 Nucl. Fusion 58 106009).

H_∞ Sliding Mode Control: A Recent Review of Applications and Design Methods

IEEE Access
The $H_{\infty }$ Sliding Mode Control ( $H_{\infty }$ SMC) approach was introduced at the onset of this millennium as a proficient strategy integrating sliding mode and $H_{\infty }$ control principles to leverage their robust attributes while ...

H-mode accelerating structures with permanent-magnet quadrupole beam focusing

Physical Review Special Topics. Accelerators and Beams, 2012
We have developed high-efficiency normal-conducting rf accelerating structures by combining H-mode resonator cavities and a transverse beam focusing by permanent-magnet quadrupoles (PMQ), for beam velocities in the range of a few percent of the speed of ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Experimental observation and edge characteristics of EDA H-mode on the HL-3 tokamak

Nuclear Fusion
The enhanced ${D_\alpha }$ (EDA) H-mode features high energy confinement together with the absence of edge localized modes (ELMs) and impurity accumulation, making it highly attractive for fusion reactors. The EDA H-mode has been observed recently in the

Phenomenological model for H-mode [PDF]

, 1985
A phenomenological model has been developed to clarify the role of the boundary configuration in the heat transport of the H-mode regime. We assume that the dominant mechanism of heat loss at the edge of the plasma is convection and that the diffusion coefficient (D/sub edge/) at the edge of the plasma increases rapidly with plasma pressure, but drops ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Density pedestal prediction model for tokamak plasmas

Nuclear Fusion
A model for the pedestal density prediction based on neutral penetration combined with pedestal transport is presented. The model is tested against a pedestal database of JET-ILW Type I ELMy H-modes showing good agreement over a wide range of parameters ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
