introduction: different environmental factors such as drugs, ionizing radiation, etc can induce apoptosis.in the present study the effects of dose- rate and post-irradiation incubation time on gamma radiation inducedapoptosis in human breast carcinoma cell line (t-47d) (invasive ductal carcinoma) was investigated. material and methods: the t-47d cells were cultured in t25 flasks and during log ...

Assuming that each subjet follows the Yonetoku relation, i.e., E rest p ∝ L 1/2 p , we performed Monte Carlo simulations in the context of a multiple subjet model (or inhomogeneous jet model) for gamma-ray bursts (GRBs), X-ray–rich GRBs (XRRs), and X-ray flashes (XRFs). For a single subjet, we found that E rest p ∝ Eiso 0.4 for large viewing angle. For the multiple subjet model under the univer...

The main aim of this article is to study an extension the Beta and Gamma matrix functions by using a two-parameter Mittag-Leffler function. In particular, we investigate certain properties these extended such as symmetric relation, integral representations, summation relations, generating relation functional relation.

Using a simple uniform jet model of prompt emissions of gamma-ray bursts (GRBs), we reproduce the observed peak energy–isotropic energy relation. A Monte Carlo simulation shows that the low isotropic energy part of the relation is dominated by events viewed from off-axis directions, and the number of the off-axis events is about one-third of the on-axis emissions. We also compute the observed e...

We introduce a new family of jump operators on Borel equivalence relations; specifically, for each countable group $\Gamma$ we the $\Gamma$-jump. study elementary properties $\Gamma$-jumps and compare them with other previously studied operators. One our main results is to establish that many groups $\Gamma$, $\Gamma$-jump \emph{proper} in sense any relation $E$ strictly higher than reducibilit...

We study the local load sharing fiber bundle model and its energy burst statistics. While it is known that avalanche size distribution of exponential, we numerically show here ($s$) corresponding ($E$) in this version have a non-linear relation ($E\sim s^{\gamma}$). Numerical results indicate $\gamma\approx 2.5$ universally for different failure threshold distributions. With numerical observati...

The human motor cortex exhibits characteristic beta (15-30 Hz) and gamma oscillations (60-90 Hz), typically observed in the context of transient finger movement tasks. The functional significance of these oscillations, such as post-movement beta rebound (PMBR) and movement-related gamma synchrony (MRGS) remains unclear. Considerable animal and human non-invasive studies, however, suggest that t...
