ns c is LBNL’s Network Simulator [20]. The simulator is written in C++; it uses OTcl as a command and configuration interface. ns v2 has three substantial changes from ns v1: (1) the more complex objects in ns v1 have been decomposed into simpler components for greater flexibility and composability; (2) the configuration interface is now OTcl, an object oriented version of Tcl; and (3) the inte...

We give a construction for a general class of vertices in superstring field theory which include integration over bosonic moduli as well as the required picture changing insertions. We apply this procedure to find a covariant action for the NS-NS sector of Type II closed superstring field theory.

We consider six dimensional N = 1 space-time supersymmetric Type IIB orientifolds with non-zero untwisted NS-NS sector B-field. The B-field is quantized due to the requirement that the Type IIB spectrum be left-right symmetric. The presence of the B-field results in rank reduction of both 99 and 55 open string sector gauge groups. We point out that in some of the models with non-zero B-field th...

introduction: hyperalgesia is considered as one the marked signs of subchronic diabetes mellitus that could affect the life style of patients. considering the evidence on the antidiabetic and analgesic effects of nigella sativa (ns), this study was designed to investigate the analgesic effects of ns on formalin-induced nociceptive responses (standard formalin test) in streptozotocin (stz)-induc...

In this work, numerical simulations were used to investigate the gravitational stochastic background produced by coalescences occurring up to z ∼ 5 of double neutron star systems. The cosmic coalescence rate was derived from Monte Carlo methods using the probability distributions for forming a massive binary and to occur a coalescence in a given redshift. A truly continuous background is produc...

Orientifolds of type II string theory admit a certain set of generalized NS-NS fluxes, including not only the three-form field strength H , but also metric and non-geometric fluxes, which are related to H by T-duality. We describe in general how these fluxes appear as parameters of an effective N = 1 supergravity theory in four dimensions, and in particular how certain generalized NS-NS fluxes ...

The Click Modular Router provides a flexible platform for protocol development and testing. Integrating the Click Modular Router with a network simulator offers the advantage of bringing this flexibility into a simulation framework. The existing integration of Click with ns-2 (nsclick) has several limitations, namely it cannot be used with generic traffic generators, transport protocols and Net...
