The `-function regularization method is used to evaluate the renormalized effective action for massless conformally coupling scalar fields propagating in a closed Friedmann spacetime perturbed by a small rotation. To the second order of the rotational parameter in the model spacetime the analytic fo

We apply the string-inspired worldline formalism to the calculation of the higher derivative expansion of one-loop effective actions in non-Abelian gauge theory. For this purpose, we have completely computerized the method, using the symbolic manipulation programs FORM, PERL and M. Explicit results
## Abstract The effects of higher order dispersion are analyzed for the first time in ultraβfast signal demultiplexing using a nonlinear optical loop mirror (NOLM). The results show that performance degradation of NOLM can occur when higher order dispersion is not negligible. Therefore, a loop fibe
The naturally occurring retinyl derivatives that promote wound healing as measured by their effects on tensile strength of healing wounds also stimulate granuloma formation induced by cotton pellets. The hexosamine and hydroxyproline contents in the granuloma affected by retinyl derivatives are also
