To explain X-ray spectra of active galactic nuclei (AGN), non-thermal activity in AGN coronae such as pair cascade models has been extensively discussed the past literature. Although and gamma-ray observations 1990s disfavored models, recent millimeter-wave nearby Seyferts establish existence weak coronal activity. Besides, IceCube collaboration reported NGC 1068, a Seyfert, hottest spot their ...
It is proposed that there exists a class of pulsars, called weak pulsars, for which the large-scale magnetosphere, and hence the gamma-ray emission, are independent of the detailed pattern of plasma production. The weak pulsar magnetosphere and its gamma-ray emission are uniquely determined by just three parameters: spin, dipole, and the spin-dipole angle. We calculate this supposedly unique pu...
To futher our understanding of the mechanisms underlying the diverse effects of altered peptide ligands (APL) on T cell activation, we used a population of nonactivated spleen cells from mice that expressed a transgenic TCR specific for myelin basic protein Ac1-11 and peptide analogues that display either enhanced or decreased affinities for TCR/MHC to address the question whether APL-induced s...
The weak transient detected by the Fermi Gamma-ray Burst Monitor (GBM) 0.4s after GW150914 has generated much speculation regarding its possible association with the black hole binary merger. Investigation of the GBM data by Connaughton et al. revealed a source location consistent with GW150914 and a spectrum consistent with a weak, short gamma-ray burst. Greiner et al. present an alternative ...
We explore the potential of INTEGRAL to improve our understanding of the low fluence regime for explosive transients, such as GRBs. We probe the nature of the so-called "WEAK" INTEGRAL triggers,when the gamma-ray instruments record intensity spikes that are below the usual STRONGsignificance thresholds. In a targeted Swift follow-up campaign,we observed 15 WEAK triggers. We find six of these ca...
Given a finite point set P ⊂ R, we call a multiset A a one-sided weak ε-approximant for P (with respect to convex sets), if |P ∩ C|/|P | − |A ∩C|/|A| ≤ ε for every convex set C. We show that, in contrast with the usual (two-sided) weak ε-approximants, for every set P ⊂ R there exists a one-sided weak ε-approximant of size bounded by a function of ε and d.
Current phenomenology suggests the presence of a compact baryon-poor energy source to cosmological gamma-ray bursts reacting to high-density matter. The association of short and long gamma-ray bursts with hyper-and suspended accretion onto slowly and rapidly spinning black holes predicts weak X-ray af-terglow emissions from short bursts, as in GRB050509B and GRB050709. Long gamma-ray bursts are...
Introduction: One of the main problems facing different societies in the world, including Iran, is population aging and its consequences. With individuals entering old age, the possibility of being afflicted with one or more chronic diseases increases, which in turn results in more use of medications and medication adherence. This study has examined medication adherence status and its related f...
In vivo evidence suggests that T-cell-derived gamma interferon (IFN-gamma) can directly inhibit the replication of herpes simplex virus type 1 (HSV-1). However, IFN-gamma is a weak inhibitor of HSV-1 replication in vitro. We have found that IFN-gamma synergizes with the innate IFNs (IFN-alpha and -beta) to potently inhibit HSV-1 replication in vitro and in vivo. Treatment of Vero cells with eit...
We compute the cosmological background radiation of gamma rays and neutrinos due to neutralino annihilation in evolving dark matter halos, assuming the observed dark matter is comprised of thermally excited neutralinos in the MSSM. The spectrum of this gamma-ray background radiation does not show strong annihilation line features, but could amount to a significant fraction of the extragalactic ...
