Sassolite Precipitation at the Restless Campi Flegrei Volcano in Italy Points to Hydrothermal Flashing by Deep Boron‐Rich Brines

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Studying the behavior of dormant volcanoes is a major challenge in volcanology. Here, we conducted a 10‐year survey of hydrothermal mineralization at Campi Flegrei, an active volcano near Naples in Italy, which last erupted in 1538. Our survey revealed a significant output of boric acid at the hydrothermal sulfate discharge area of Pisciarelli,

A Hybrid Method Using Slime Mold Algorithm and Genetic Algorithm for Feature Selection Problems in Intrusion Detection Systems

Engineering Reports, Volume 7, Issue 7, July 2025.
In this paper, the slime mold algorithm (SMA) and genetic algorithm (GA) as metaheuristic algorithms are combined to create a novel hybrid intrusion detection (ID) method considering feature selection for classification problems. The effectiveness of this suggested approach is also evaluated in comparison to other well‐known methods like GA, PSO, GOA ...
