Computer‐Based Design to Improve Bacillus thuringiensis Chitinase for Industrial Applications

ChemistryOpen, Volume 15, Issue 4, April 2026.
Hotspot‐guided mutagenesis identifies Gly291 as a key catalytic determinant in Bacillus thuringiensis chitinase. Substitution with alanine improves substrate accommodation and lowers the activation barrier by ∼47%, reducing it from 94.66 to 49.83 kcal/mol. Structural integrity is retained while catalytic efficiency is enhanced, demonstrating a rational

Improving SAR‐Based Classification of Arctic Lake, Bay and Lagoon Ice by Accounting for Under Ice Water Salinity

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Arctic lake, bay and lagoon ice regimes play a crucial role in understanding permafrost stability, hydrology, and carbon cycling in permafrost regions. This study integrates field and Synthetic Aperture Radar (SAR) data from Sentinel‐1 to improve the classification of Arctic lake, bay and lagoon ice regimes, with a particular focus on the ...

The Split‐Station Architecture: Decoupling Transformation From Distribution via Medium‐Voltage Superconducting Virtual Bus Extensions

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes the split‐station architecture, which uses high‐temperature superconducting (HTS) cables as ‘virtual bus extensions’ to decouple transformation from distribution in medium‐voltage systems. PYPOWER simulations validated against Project Hydra 13.8 kV specifications demonstrate that a 3‐km HTS link reduces voltage drop by 46 ...

Wind variability and its effect on transmission line capacity estimation

Energy Conversion and Management: X
Transmission line ampere capacity, i.e. ampacity, can be determined in real time using dynamic thermal rating (DTR). Standard DTR systems rely on weather data averaged over multi-minute windows. While sufficient for most weather parameters, this approach
