We investigate some models of compact objects in the general relativity theory with cosmological constant $\Lambda$, based on two density profiles, one them attributed to Stewart and other Durgapal Bannerji, proposed literature model "neutron stars". For them, a nonlocal equation state is obtained as consequence chosen metric. In another direction, we obtain solution for configurations null rad...

This paper considers the effects of placing an absolutely continuous prior distribution on the regression coefficients of a linear model. We show that the posterior expectation is a matrix-shrunken version of the least squares estimate where the shrinkage matrix depends on the derivatives of the prior predictive density of the least squares estimate. The special case of the normal-gamma prior, ...

Proof: The first and second derivatives of f(z) = − ln(1 − pz) are f ′(z) = p 1−pz and f ′′(z) = p (1−pz)2 = (f ′(z))2, respectively, and f j(0) = 0 for j ≥ 1, therefore d dzm f j(z) ∣∣ z=0 = 0 for j > m and thus (2) is true for j > m. When n = j = 1, we have d n dzn f j(z) ∣∣ z=0 = f ′ k(0) = p, ∑n j′=1 F (n, j ′) j! (j−j′!) [f ′(z)]nf j−j ′ (z) ∣∣∣ z=0 = p, and F (n, j)j!pn = p, therefore, (2...

Using the murine colon adenocarcinoma C-26 cell line, engineered to release granulocyte colony-stimulating factor (G-CSF) (C-26/G-CSF), were studied the mechanisms responsible for inhibition of tumor take in syngeneic animals and of regression of an established tumor in sublethally irradiated mice injected with these cells. Immunocytochemistry and in situ hybridization, performed to characteriz...

We explore a particular fully parametric approach to quantile regression and show that this approach can be very successful. Motivated by the provision of reference charts, we work in the specific context of a positive response variable, whose conditional distribution is modelled by the generalised gamma distribution, and a single covariate, the dependence of parameters of the generalised gamma...

The afterglow of GRB 170817A has been detected for more than three years, but the origin multi-band light curves remains under debate. A classical top-hat jet model is faced with difficulties in producing a shallow rise as observed $(F_{\nu} \propto T^{0.8})$. Here we reconsider stratified ejecta energy profile $E(>\Gamma \beta)=E_0(\Gamma \beta)^{-k}$ burst, where $\Gamma$ and $\beta$ are Lore...

Two-temperature spherical accretion flows produce ≈ 100 Mev gamma-rays from the decay of neutral pions created in proton-proton collisions close to the black hole; they also produce ∼ 10 keV X-rays by bremsstrahlung emission at large radii. The gamma-ray to X-ray luminosity ratio is nearly independent of black hole mass and accretion rate. It does depend sensitively on the radial density profil...
