Advances and challenges in multiscale biomolecular simulations: artificial intelligence‐driven paradigm shift

open access: yesQuantitative Biology, Volume 14, Issue 2, June 2026.
Abstract Molecular simulation techniques have become an invaluable tool for elucidating the fundamental principles of life at the molecular level. After nearly five decades of development, biomolecular simulations have evolved to enable the quantitative characterization of complex biomolecular events, such as protein folding, conformational dynamics ...

A 28-GHz Cascode Inverse Class-D Power Amplifier Utilizing Pulse Injection in 22-nm FDSOI

open access: yesIEEE Access, 2020
Current Mode Class-D (CMCD) Power Amplifiers are of particular interest in outphasing transmitters or Doherty configuration. This is because the output capacitance can be absorbed in the RLC output matching network and 100% theoretical efficiency.

Investigation of the effect of weak non-linearities on P1dB and efficiency of class B/J/J* amplifiers [PDF]

open access: yes, 2018
The variation of phase of the current through the non-linear intrinsic capacitances of a high-power RF device caused by the variation of the phase in the continuum of drain voltage waveforms in Class B/J/J* leads to a reduction of intrinsic drain current

A Serious Game for Mould Prevention Education: A Comparative Study With Video‐Based Learning

open access: yesJournal of Computer Assisted Learning, Volume 42, Issue 2, April 2026.
ABSTRACT Background Indoor mould growth poses a significant risk to occupant health and building durability, particularly in climates with high humidity and inadequate ventilation. Traditional educational approaches often struggle to maintain learner engagement and support long‐term behaviour change.

Unveiling Protist Composition and Diversity Patterns With eDNA Metabarcoding: Comparing Short‐ and Long‐Read Approaches

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Environmental DNA (eDNA) metabarcoding is widely used for biodiversity monitoring, but short‐read sequencing limits detailed taxonomic identification, especially for protists. In a comparison of short‐ and long‐read approaches in the Belgian North Sea, long‐read metabarcoding provided deeper taxonomic assignment under the applied workflows and improved

CDC42‐Effector Proteins Regulate Higher Order Structure of Septins Required for CNS Myelin Integrity

open access: yesGlia, Volume 74, Issue 3, March 2026.
CDC42‐effector proteins 1/2 are present in CNS myelin. They facilitate the higher order structure of myelin septin filaments. Their loss impairs septin‐dependent scaffolding of myelin. Myelin outfoldings do not cause secondary neuropathology per se. ABSTRACT The regular structure of CNS myelin requires specialized structural proteins, including septin ...
