Cluster analysis of earthquake hypocenters in Azerbaijan and surrounding territories
The research focuses on seismic events that occurred in Azerbaijan and adjacent territories, regions known for strong seismic activity. We analyze a catalog of recorded earthquakes between 2010 and 2023, extracting the locations of the earthquake hypocenters for study purposes. Using statistical methods and cluster analysis tools, we developed a procedure for partitioning hypocenter clusters. The procedure begins with estimates of the Morisita Index, which is suitable for preliminary assessment…

8 journalists given lengthy jail terms as Azerbaijan crushes free press - Committee to Protect Journalists
New York, June 23, 2025— Eight Azerbaijani journalists have received prison sentences ranging from 7 ½ to 15 years, as part of an ongoing series of media trials likely to obliterate independent reporting in the Caucasus nation. In a closed-door trial on Monday, columnist and peace activist Bahruz Samadov was sentenced by a court in...

Collective communication in a transparent world: Phase transitions in a many-body Potts model and social-quantum duality
We consider the Schelling-like social competition reflected in "dynamics of opinions" among groups of agents ("communities") in a highly transparent world. Specifically, we investigate a $q$-state Potts spin system with competing two- and three-body interactions on a complete graph. Agents interact through pairwise repulsion (opposing opinions) between different communities and three-body attraction (shared opinions) within the same community. In the thermodynamic limit, we identify variants of…

Cooperative Jahn-Teller dynamics of boron clusters in the infrared conductivity of heavy fermion metal CeB6 and unconventional superconductor ZrB12
A thorough study of the wide-range (40-35000 cm-1) dynamic conductivity and permittivity spectra of the archetypal heavy fermion metal CeB6 and unconventional superconductor ZrB12 was carried out at room temperature. Both the Drude-type components and overdamped excitations were separated and analyzed. An additional absorption band observed above 200 cm-1 was attributed to the cooperative Jahn-Teller dynamics of the boron complexes in CeB6 and ZrB12. It was shown that nonequilibrium electrons p…

The Scintillator Surface Detector of the Pierre Auger Observatory
Data collected so far by the Pierre Auger Observatory have enabled major advances in ultra-high energy cosmic ray physics and demonstrated that improved determination of masses of primary cosmic-ray particles, preferably on an event-by-event basis, is necessary for understanding their origin and nature. Improvement in primary mass measurements was the main motivation for the upgrade of the Pierre Auger Observatory, called AugerPrime. As part of this upgrade, scintillator detectors are added to …
