Focus on dynamics of particles in turbulence

New Journal of Physics, 2014
Studies on the dynamics of particles in turbulence have recently experienced advances in experimental techniques, numerical simulations and theoretical understandings. This ‘focus on’ collection aims to provide a snapshot of this fast-evolving field.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Gyrokinetic study of multiple electrostatic and electromagnetic electron-temperature-gradient modes and relevant transport in tokamak finite βe plasmas

Nuclear Fusion
We present a comprehensive study of the multiple electrostatic and electromagnetic electron temperature gradient (ETG) modes with a significant upgrading of the gyrokinetic code HD7.

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

FEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Research on stiff transport in electron heating dominated plasmas in EAST

Nuclear Fusion
An experiment was conducted on the Experimental Advanced Superconducting Tokamak (EAST) to investigate the properties of stiff transport in an electron-heated H-mode plasma, using a power deposition scan with electron cyclotron resonance heating (ECRH ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Gyrokinetic simulation of the interplay between ion temperature gradient turbulence and reversed shear Alfvén Eigenmodes

Nuclear Fusion
A nonlinear gyrokinetic simulation, which incorporates both the reversed shear Alfvén eigenmode (RSAE) and the ion temperature gradient (ITG) turbulence, has been performed using the electromagnetic gyrokinetic Particle-In-Cell (PIC) code GEM.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Enhanced turbulent transport and drift reduction in divertors at the detachment onset

Nuclear Fusion
At the onset of detachment, measurements show that radial turbulent particle transport $\left(\tilde{\Gamma}_\mathrm{r}\right)$ increases by a factor of $2-4$ above the dissipative region in the near scrape-off layer (SOL) of both single-null (SN) and ...
