Unitary representations and von Neumann’s continuous geometries

We prove that the unit group of a nondiscrete irreducible, continuous ring, in the sense of John von Neumann, does not admit any nontrivial unitary representation continuous with respect to the strong operator topology.

Dynamic and Post-Deformation Static Aging as an Integrated Approach to Thermomechanical Processing of TiNi Shape Memory Alloys

The effect of thermomechanical processing (TMP) parameters on the structural-phase evolution and properties of Ni-enriched Ti–50.8 at.% Ni shape memory alloy was investigated. Compression deformation was performed at T = 300–500 °C, accompanied by the development of dynamic aging...

Assessment of anthropogenic trace metal and surfactant influence on a coastal area in the Northern Adriatic Sea using scientific diving

Abstract Thisvestigates the anthropogenic footprint on a coastal marine environment near the Istrian coast (Northern Adriatic Sea) through a scientific diving field campaign conducted in September 2025. The investigation aimed to evaluate local seawater quality by combining onsit...
