NON-THERMAL EMISSION FROM CATACLYSMIC VARIABLES: IMPLICATIONS ON ASTROPARTICLE PHYSICS

Acta Polytechnica, 2013
We review the lines of evidence that some cataclysmic variables (CVs) are the sources of non-thermal radiation. It was really observed in some dwarf novae in outburst, a novalike CV in the high state, an intermediate polar, polars, and classical novae ...

Exploring Tolerance Towards Corruption in the European Union Through Experienced Corruption, Perceived Corruption and Institutional Trust

Business Ethics, the Environment &Responsibility, Volume 35, Issue 2, Page 1279-1304, April 2026.
ABSTRACT Corruption is a major problem that undermines the foundations of democracy and reduces citizens' trust in institutions. However, even in the world's most advanced countries, citizens accept certain levels of corruption. This tolerance towards corruption (TC) reduces the impact of anti‐corruption actions and ends up giving a patina of normality

Broad-Band Variability in Accreting Compact Objects

Acta Polytechnica CTU Proceedings, 2015
Cataclysmic variable stars are in many ways similar to X-ray binaries. Both types of systems possess an accretion disk, which in most cases can reach the surface (or event horizon) of the central compact object.

Polanyi on crisis: The United States, fascism and ecological break‐down

Journal of Law and Society, Volume 53, Issue S1, Page S131-S150, April 2026.
Abstract This article uses Karl Polanyi's understanding of the crisis inherent in liberal economics to analyse a contemporary crisis—Trump's global tariff agenda. It argues that Trump's tariff agenda conforms to Polanyi's interpretation of how the crisis of liberal economics can disintegrate into more malignant forces.

eROSITA selection of new period-bounce cataclysmic variables

Astronomy & Astrophysics
Context. Between 40% and 80% of cataclysmic variables (CVs) are expected to have evolved past the period-minimum and contain a degenerate donor. However, observational surveys for CVs have only been able to detect a few of these highly evolved “period ...

SWSex Stars, Old Novae, and the Evolution of Cataclysmic Variables

Acta Polytechnica CTU Proceedings, 2015
The population of cataclysmic variables with orbital periods right above the period gap are dominated by systems with extremely high mass transfer rates, the so-called SW Sextantis stars.

Minute-Cadence Observations of the LAMOST Fields with the TMTS: IV—Catalog of Cataclysmic Variables from the First 3-yr Survey

Universe
The Tsinghua University–Ma Huateng Telescopes for Survey (TMTS) started to monitor the LAMOST plates in 2020, leading to the discovery of numerous short-period eclipsing binaries, peculiar pulsators, flare stars, and other variable objects.

Study of Cataclysmic Variables with the Satellites LOFT and Gaia

Acta Polytechnica CTU Proceedings, 2015
The goal of this paper is to discuss the capabilities of ESA satellite missions Gaia (already in space) and LOFT (considered for the ESA M4 slot) for investigation of cataclysmic variables (CVs).

CATACLYSMIC VARIABLES AND GAMMA-RAY SOURCES [PDF]

EAS Publications Series, 2013
The cataclysmic variables are associated with high energy events and probably many of them could be potential gamma-ray sources. Up to now Fermi-LAT detected 3 gamma-ray transients, which belong to CVs and related objects: V407 Cyg, N Sco 2012 and N Mon 2012 = V959 Mon. We present the first multicolour observations of the slow classical nova V959 Mon.

Nation‐Building in the Wake of Empire: Identifying Patterns of Minority Policies in the Aftermath of Soviet Collapse

Nations and Nationalism, Volume 32, Issue 2, Page 386-401, April 2026.
ABSTRACT The collapse of the USSR forced newly independent states to forge national identities while grappling with imperial legacies. This study investigates nation‐building strategies in post‐Soviet states during 1990–1999, using the Nation‐Building Policies (NBP) dataset from the ETHNICGOODS project, which includes all socially and politically ...
