Application of PSO for optimal coordination of directional over-current relays in distribution system with distributed renewable energy sources [PDF]

, 2021
The use of distributed renewable energy sources (D-RES) in the electrical network has expanded greatly. However, integration of these resources into distribution systems caused more problems in protection related issues such as mis-coordination and ...

Tracing Slow Winds from T Tauri Stars via Low Velocity Forbidden Line Emission [PDF]

, 2016
Using Keck/HIRES spectra {\Delta}v ~ 7 km/s, we analyze forbidden lines of [O I] 6300 {\AA}, [O I] 5577 {\AA} and [S II] 6731 {\AA} from 33 T Tauri stars covering a range of disk evolutionary stages.

Observer dependence for the phonon content of the sound field living on the effective curved space-time background of a Bose-Einstein condensate

, 2004
We demonstrate that the ambiguity of the particle content for quantum fields in a generally curved space-time can be experimentally investigated in an ultracold gas of atoms forming a Bose-Einstein condensate.

Structural mechanisms for cold‐adapted activity of phosphoenolpyruvate carboxykinase

Protein Science, Volume 34, Issue 11, November 2025.
Abstract Temperature is a critical factor in enzyme function, as most enzymes are thermally activated. Across Earth's diverse environments (−20 to 120°C), enzymes have evolved to function optimally at their organism's growth temperature. Thermophilic enzymes must resist denaturation, while psychrophilic enzymes must maintain activity with limited ...
