Short $\gamma$-ray burst (sGRB) jets form in the aftermath of a neutron star merger, drill through disk winds and dynamical ejecta, extend over four to five orders magnitude distance before breaking out ejecta. We present first 3D general-relativistic magnetohydrodynamic sGRB simulations span this enormous scale separation. They feature three possible outcomes: jet+cocoon, cocoon, neither. Typi...

Breaking waves have ability to transport large quantities of sediment and significant impact on coastal structures morphology. Hence, modeling of wave breaking is an important subject in coastal and marine engineering. In this research, the periodic wave breaking process on a plane slope is studied experimentally and numerically. Laboratory experiments were conducted to record water surface ele...

We study the effects of large scale magnetic fields on dynamics charged particles near a rotating black hole. consider scenario in which initially neutral geodesic orbits equatorial plane become ionized, and hence they are destabilized by charging process. Fraction then accelerated out follow jet like trajectories with relativistic velocities. explore non axisymmetric systems field is inclined ...

to study the effects of chilling on dormancy breaking and the increased germination characteristics of nepeta (germination percent and speed, seedling length, vigor index, wet and dry weight), a factorial experiment in a completely randomized design with 4 replications was implemented in a laboratory in 2014. factor a was the chilling treatment in three levels (control, one-month and two-month ...

For some choices of soft SUSY–breaking parameters, the LSP is a stable neutralino χ̃1, the NLSP is a chargino χ̃1 almost degenerate in mass with the LSP (∆mχ̃1 ≡ mχ̃± 1 −mχ̃0 1 ∼ mπ−few GeV), and all other sparticles are relatively heavy. In this case, detection of sparticles in the usual, mSUGRA–motivated signals will be difficult, since the decay products in χ̃1 → χ̃1 . . . will be very soft, and al...

using of nanofluids and ducts with corrugated walls are both supposed to enhance heat transfer, by increasing the heat transfer fluid conductivity and the heat transfer area respectively. use of a diverging duct with a jet at inlet section may further increase heat transfer by creating recirculation zones inside the duct. in this work two-dimensional incompressible laminar flow of a nanofluid e...

Experiments have been performed using a simplified, Newtonian forced, global circulation model to investigate how variability of the tropospheric jet can be characterized by examining the combined fluctuations of the two leading modes of annular variability. Eddy forcing of this variability is analyzed in the phase space of the leading modes using the vertically integrated momentum budget. The ...

In this paper we present the theoretical basis for the modeling of weakly gravitationally lensed extended sources that are polarized. This technique has been used in the past to constrain the mass profiles of galaxies projected against the jet of the quasar 3C9. Since then, work has been done to improve both the measurement and theoretical modeling of the lensing signal, which manifests itself ...
