The lower bound on the period of uniform rotation of neutron stars (NS) with causal equation of state (EOS), Pmin, is shown to be determined, with a high precision, by the upper bound on the surface redshift of static neutron star models, zmax. We obtain zmax = 0.851, which turns out to be about 5% lower than upper bound obtained by Lindblom (1984). Using then the empirical formula for the maxi...

The statistical properties of endomorphisms under the assumption that the associated Perron– Frobenius operator is quasicompact are considered. In particular, the central limit theorem, weak invariance principle and law of the iterated logarithm for sufficiently regular observations are examined. The approach clarifies the role of the usual assumptions of ergodicity, weak mixing, and exactness....

Soft tissue sarcomas (STS) are a heterogeneous group of tumors (Table 1) that account for approximately 1% of all adult cancer (Clark et al., 2005). There are more than 50 subtypes that are stratified by their histological appearance, presence or absence of characteristic gene translocations, or sensitivity to chemotherapy. They can be found in nearly any site in the body, but upper and lower e...

We investigate the conjecture by Sikora, Stawarz & Lasota (2007) that the observed AGN–radioloudness bimodality can be explained by the morphology related bimodality of black-hole spin distribution in the centers of galaxies: central black holes in giant elliptical galaxies may have (on average) much larger spins than black holes in spiral/disc galaxies. We study how accretion from a warped dis...

Newcastle disease virus (NDV) was isolated from a field outbreak in pigeons. The virus was characterized by haemagglutination test (HA) and confirmed by haemagglutination inhibition test (HAI). The pathotyping was done by mean death time (MDT), intracerebral pathogenicity index (ICPI) and intravenous pathogenicity index (IVPI). The ELD50 of the velogenic strain was 10/0.1 ml. Thirty-nine pigeon...
