The Periods of Cataclysmic Variables [PDF]
International Astronomical Union Colloquium, 1987 AbstractThe present status of the period studies of cataclysmic variables is briefly reviewed, mainly from the observational point of view. A few comments on individual objects include EM Cyg, Z Cha, WZ Sge and AM CVn.

Molecular Alterations in Osteosarcomas of the Oral and Maxillofacial Region: A Scoping Review
Journal of Oral Pathology &Medicine, EarlyView.ABSTRACT Background Given the rarity and aggressive nature of osteosarcomas (OS) in the oral and maxillofacial region, understanding their molecular alterations is essential to improve diagnosis, prognosis, and guide targeted therapies. This study aimed to map molecular alterations associated with oral and maxillofacial OS, providing an overview of the

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 ...

Radio emission from cataclysmic variables [PDF]
Astrophysics and Space Science, 1987 AbstractThe study of radio emission from cataclysmic variables (CVs) is a new and developing field. Radio emission from novae, recurrent novae, dwarf novae and each of the subclasses (AM Her and OQ Her) of magnetic CVs have now been reported and are reviewed here.

Rotation and Cataclysmic Variables [PDF]
Symposium - International Astronomical Union, 2004 Cataclysmic Variables are binary star systems and so are closely connected to the subject of this meeting. The stars revolve around the center of mass of the system. The gas lost by the secondary through the inner Lagrangian point enters the Roche lobe of the white dwarf with the angular momentum of the L1point and, therefore, forms an accretion disk ...

Nations and Nationalism, EarlyView.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 ...

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.

Public Administration, EarlyView.ABSTRACT New research argues that robust governance based on flexible adaptation and proactive innovation is needed in order to uphold core public functions, purposes, and values in times of societal turbulence. However, we have limited knowledge of the conditions for enhancing robust governance.

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.

Rapid Keck Spectroscopy of Cataclysmic Variables [PDF]
International Astronomical Union Colloquium, 2004 Abstract We present an analysis of Rapid Keck Spectroscopy of the CVs AM Her (polar) and SS Cyg (dwarf nova). We decompose the spectra into constant and variable components and identify different types of variability in AM Her with different characteristic timescales.
