Modelling of optical emissions enhanced by the HF pumping of the ionospheric F-region [PDF]
Annales Geophysicae, 2012 Strong enhancement of the optical emissions with excitation threshold from 1.96 eV (630.0 nm from O(1D)) up to 18.75 eV (427.8 nm from N2+(1NG)) have been observed during experiments of the ionosphere modification by high power HF radio waves ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

An Adaptively Accelerated Lucy-Richardson Method for Image Deblurring
EURASIP Journal on Advances in Signal Processing, 2008 We present an adaptively accelerated Lucy-Richardson (AALR) method for the restoration of an image from its blurred and noisy version. The conventional Lucy-Richardson (LR) method is nonlinear and therefore its convergence is very slow.

Molecular Oncology, EarlyView.We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Sharp exponent of acceleration in general non-local equations with a weak Allee effect
Annales de la Faculté des sciences de Toulouse : MathématiquesWe study an acceleration phenomenon arising in monostable integro-differential equations with a weak Allee effect. Previous works have shown its occurrence and have given correct upper bounds on the rate of expansion in some particular cases, but precise lower bounds were still missing.

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Thermodynamically consistent entropic late-time cosmological acceleration
European Physical Journal C: Particles and Fields, 2022 Entropic-force cosmology provides, in contrast with dark energy descriptions, a concrete physical understanding of the accelerated expansion of the universe.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Retrograde trans‐synaptic degeneration (rTSD) from posterior visual pathway lesions in multiple sclerosis (MS) is characterized by hemi‐macular ganglion cell‐inner plexiform layer (GCIPL) thinning and contralateral visual field loss.

The effects of numerical acceleration techniques on PIC-MCC simulations of ion thrusters
AIP Advances, 2020 The particle-in-cell-Monte Carlo collision method has been widely used in simulation studies of ion thrusters. Due to the huge computational demand of such simulations, numerical acceleration techniques are required.
