In this paper, we study the quasinormal modes(QNMs) of massless scalar perturbations to probe Van der Waals like small and large black holes(SBH/LBH) phase transition (charged) AdS holes in 4-dimensional Einstein Gauss-Bonnet gravity. We find that signature SBH/LBH isobaric process can be detected since slopes QNMs frequencies change drastically different near critical point. The obtained resul...

The Bekenstein-Hawking area-entropy relation SBH = A/4 is derived for a class of five-dimensional extremal black holes in string theory by counting the degeneracy of BPS soliton bound states.

In this study we measured the degrees to which the Schottky barrier heights (SBHs) are lowered in ZnO nanowire (NW) devices under illumination with UV light. We measured the I-V characteristics of ZnO nanowire devices to confirm that ZnO is an n-type semiconductor and that the on/off ratio is approximately 10(4). From temperature-dependent I-V measurements we obtained a SBH of 0.661 eV for a Zn...

The social brain hypothesis (SBH) contends that cognitive demands associated with living in cohesive social groups favour the evolution of large brains. Although the correlation between relative brain size and sociality reported in various groups of birds and mammals provides broad empirical support for this hypothesis, it has never been tested in rodents, the largest mammalian order. Here, we ...

در این تحقیق برای اندازه گیری گونه به گونه آنتیموان به وسیله روش اسپکتروفتومتری محلول کمپلکس تشکیل شده از هیدرید استیبین با دی اتیل دی تیوکاربامات نقره (SDDC)، یک سیستم ناپیوسته تولید الکتروشیمیایی هیدرید مورد استفاده قرار گرفت. روش کار بدین گونه است که ابتدا Sb(III) و Sb(V) به استیبین (SbH3) کاهش داده شده و سپس طی واکنش با (SDDC) یک کمپلکس رنگی تولید می گردد. اثر عوامل مختلفی چون جن...

Subcortical band heterotopia (SBH), also known as ‘double cortex’ syndrome, is characterized by a band of heterotopic neurons interspersed in the white matter between the cortex and the lateral ventricles and is usually a severe disease with patients showing variable degrees of developmental delay, intellectual disability, motor impairment and epilepsy [1]. This is a true neuronal migration dis...

Subcortical band heterotopia (SBH) is a disorder of neuronal migration most commonly due to mutations of the Doublecortin (DCX) gene. A range of phenotypes is seen, with most patients having some degree of epilepsy and intellectual disability. Advanced diffusion and structural magnetic resonance imaging (MRI) sequences may be useful in identifying heterotopias and dysplasias of different sizes ...

Abstract We study the dynamical properties of thermodynamic phase transition (PT) a charged AdS black hole (BH) with global monopole via Gibbs free energy landscape and reveal effects on kinetics PTs. First, we briefly review thermodynamics BH monopole. Then, introduce to investigate stability states. Because thermal fluctuations, small (SBH) state can transit large (LBH) state, vice versa. Fur...

We introduce a framework to build a survival/risk bump hunting model with a censored time-to-event response. Our Survival Bump Hunting (SBH) method is based on a recursive peeling procedure that uses a specific survival peeling criterion derived from non/semi-parametric statistics such as the hazards-ratio, the log-rank test or the Nelson--Aalen estimator. To optimize the tuning parameter of th...

Pharaonis phoborhodopsin (ppR; also pharaonis sensory rhodopsin II, psRII) is a receptor of the negative phototaxis of Natronobacterium pharaonis. By spectroscopic titration of D193N and D193E mutants, the pK(a) of the Schiff base was evaluated. Asp193 corresponds to Glu204 of bacteriorhodopsin (bR). The pK(a) of the Schiff base (SBH(+)) of D193N was approximately 10.1-10.0 (at XH(+)) and appro...
