Reconstructing PSP/ISOIS Pitch-angle-resolved Intensities Using Unsupervised Learning
The Astrophysical JournalThe Integrated Science Investigation of the Sun (IS⊙IS) on board the Parker Solar Probe provides high-resolution measurements of energetic particles across a broad energy range. Of particular interest are the pitch-angle distributions (PADs), which offer

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Predictions of improved confinement in SPARC via energetic particle turbulence stabilization
Nuclear Fusion, 2023 The recent progress in high-temperature superconductor technologies has led to the design and construction of SPARC, a compact tokamak device expected to reach plasma breakeven with up to 25 MW of external ion cyclotron resonant heating (ICRH) power ...

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.

ENERGETIC PARTICLE DIFFUSION IN STRUCTURED TURBULENCE [PDF]
The Astrophysical Journal, 2012 In the full-orbit particle simulations of energetic particle transport in plasmas, the plasma turbulence is typically described as a homogeneous superposition of linear Fourier modes. The turbulence evolution is, however, typically a nonlinear process, and, particularly in the heliospheric context, the solar wind plasma is inhomogeneous due to the ...

Current status and possible extension of the global neutron monitor network
Journal of Space Weather and Space Climate, 2020 The global neutron monitor network has been successfully used over several decades to study cosmic ray variations and fluxes of energetic solar particles. Nowadays, it is used also for space weather purposes, e.g. alerts and assessment of the exposure to

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
