Disturbing of a spacetime geometry may result in the appearance of an oscillating and damped radiation the so-called quasinormal modes. Their periods of oscillations and damping coefficients carry unique information about the mass and the angular momentum, that would allow one to identify the source of the gravitational field. In this talk we present recent bounds on the diffused energy, applic...

Abstract We consider a generalisation of the Basilica group to all odd primes: p -Basilica groups acting on -adic tree. show that have -congruence subgroup property but not congruence nor weak property. This provides first examples weakly branch with such properties. In addition, give branch, which are super strongly fractal. compute orders quotients these groups, enable us determine Hausdorff ...

In this paper, we introduce the notion of (i-v) fuzzy (weakly) completely regular subsemigroup of a semigroup S and study their different properties. We show that every (i-v) fuzzy completely regular subsemigroup of a semigroup S is a union of (i-v) fuzzy subgroups of S. We also characterize (i-v) fuzzy completely regular subsemigroup by (i-v) fuzzy semilattice of (i-v) fuzzy subgroups. 2010 AM...

We compute characteristic (quasinormal) frequencies corresponding to decay of a massive charged scalar field in a Reissner-Nordstrom black hole background. It proves that, contrary to the behavior at very late times, at the stage of quasinormal ringing the neutral perturbations will damp slower than the charged ones. In the limit of the extremal black hole the damping rate of charged and neutra...

We investigate single-view algorithms as an alternative to multi-view algorithms for weakly supervised learning for natural language processing tasks without a natural feature split. In particular, we apply co-training, self-training, and EM to one such task and find that both selftraining and FS-EM, a new variation of EM that incorporates feature selection, outperform cotraining and are compar...

BACKGROUND Prolonged febrile seizures constitute an initial precipitating injury (IPI) commonly associated with refractory mesial temporal lobe epilepsy (RMTLE). In order to investigate IPI influence on the transcriptional phenotype underlying RMTLE we comparatively analyzed the transcriptomic signatures of CA3 explants surgically obtained from RMTLE patients with (FS) or without (NFS) febrile ...

Complex frequencies associated with quasinormal modes for large ReissnerNordström Anti-de Sitter black holes have been computed. These frequencies have close relation to the black hole charge and do not linearly scale with the black hole temperature as in Schwarzschild Anti-de Sitter case. In terms of AdS/CFT correspondence, we found that the bigger the black hole charge is, the quicker for the...

This study was performed to investigate some clinical parameters of febrile seizures (FSs) in patients with epilepsy, testing any possible correlation between those parameters and the type of subsequent epilepsy. One hundred and nine patients with epilepsy having a history of FSs were evaluated for age at onset of FSs, interval between first FS and first afebrile seizure, recurrence rate, type ...

Activated neuronal groups engage in rhythmic synchronization in the gammafrequency range (30-80Hz). Changes in the level of gamma synchronization are seen in the cortex during a variety of cognitive tasks including working memory maintenance (Pesaran et al., 2002), attentional selection (Fries et al., 2001), and perceptual awareness. Several computational and experimental studies investigating ...

Objectives Dental instruments may serve as a route of infection transmission. The necessity of dismantling of Friction-Style (FS) and SpringStyle (SS) mechanical torque limiting devices (MTLDs) prior to disinfection and sterilization is a matter of debate, aside fromthe fact that it is difcult and time-consuming. This study sought to assess the effect of dismantling of components on quality of ...
