Galindo–Garcia identity-based signature (GG IBS) is an efficient (IBS) whose security proven under the discrete logarithm (DL) assumption. Since original reduction of GG IBS loose, there are some works to improve factor. However, such improvements do not achieve tight sufficiently, or efficiency resulting scheme much worse than scheme. In this paper, we propose a new improvement IBS. The propos...

Thermal rate constants are calculated for the H + CH(4) --> CH(3) + H(2) reaction employing the potential energy surface of Espinosa-Garcia (Espinosa-Garcia, J. J. Chem. Phys. 2002, 116, 10664). Two theoretical approaches are used. First, we employ the multiconfigurational time-dependent Hartree method combined with flux correlation functions. In this way rate constants in the range 225-400 K a...

A previously-developed hybrid particle-continuum method [J. B. Bell, A. Garcia and S. A. Williams, SIAM Multiscale Modeling and Simulation, 6:1256-1280, 2008] is generalized to dense fluids and two and three dimensional flows. The scheme couples an explicit fluctuating compressible Navier-Stokes solver with the Isotropic Direct Simulation Monte Carlo (DSMC) particle method [A. Donev and A. L. G...
