International Journal of Psychology, Volume 61, Issue 2, April 2026.ABSTRACT This panel study examines changes in attitudes towards Ukrainian and Russian minorities in the Czech Republic and their links to disinformation beliefs and democratic commitment. The data were obtained from 490 respondents in a Czech quota sample (age 18–69; M = 46.09, SD = 13.40; 45.7% women).

Parametric Study of High Frequency Pulse Detonation Tubes [PDF]
, 2008 This paper describes development of high frequency pulse detonation tubes similar to a small pulse detonation engine (PDE). A high-speed valve injects a charge of a mixture of fuel and air at rates of up to 1000 Hz into a constant area tube closed at one

Wave Propagation in Non‐Uniform Media by Linear Expansion of the Refraction Law
PAMM, Volume 26, Issue 1, March 2026.ABSTRACT The propagation of mechanical waves in an unbounded, non‐uniform medium can be described by using curvilinear coordinates centered at the source position. The Frenet coordinate system, with origin on a point riding a wave, is used as a basis for the curvilinear coordinates.

Deep Earthquakes Can Generate Larger Co‐Seismic Displacements Than Shallow Events
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract We report the counter‐intuitive observation that a deep earthquake can generate larger co‐seismic displacements than a shallow event across a broad region (e.g., >4° from epicenter). This finding is based on a detailed comparative GNSS analysis of the co‐seismic displacement observations from two MW 8.3 events—the 2013 598.1 km‐deep Okhotsk ...

Multi-dimensional numerical simulations of type Ia supernova explosions
, 2008 The major role type Ia supernovae play in many fields of astrophysics and in particular in cosmological distance determinations calls for self-consistent models of these events.

Gamma-Ray Bursts from Primordial Quark Objects in Space [PDF]
, 1997 We investigate the possibility that gamma-ray bursts originate in a concentric spherical shell with a given average redshift and find that this is indeed compatible with the data from the third BATSE (3B) catalog.
