Space Weather, Volume 23, Issue 7, July 2025.Abstract Ionospheric scintillation caused by space weather impacts the accuracy and availability of GNSS services and is considered a natural hazard for aviation and other GNSS users. Increased solar activity in 2021–2023, attributed to the ascending phase of the 25th solar cycle, caused an amplification of ionospheric disturbances including the ...

SPH simulations of Shakura-Sunyaev instability at intermediate accretion rates [PDF]
, 2003 We show that a standard Shakura-Sunyaev accretion disc around a black hole with an accretion rate lower than the critical Eddington limit does show the instability in the radiation pressure dominated zone.

Identification of inhibitors of the Salmonella FraB deglycase, a drug target
FEBS Open Bio, Volume 15, Issue 5, Page 773-792, May 2025.A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.
