The literature, based on US Vietnam veterans, suggests that posttraumatic stress disorder (PTSD) is associated with increased criminal activity, especially violence, alcohol, and drug abuse, although more recent studies, which tested data from the Un

Dysembryoplastic neuroepithelial tumor (DNT) was first characterized in 1988 by Daumas-Duport and Scheithauer [1], who described 39 cases in children with morphologically distinct brain tumors. Partial complex seizures (PCSs), well-defined neuroimage

Periodically segmented waveguide (PSW) mode expanders can be realized simply, using a single step lithography. In this paper such devices are studied numerically, with respect to high-/spl Delta/ silica waveguides and InP strip waveguides. The effici

Modal properties of periodically segmented waveguides (PSWs) are analyzed by using the beam-propagation method and coupled-mode theory. The modal effective indices in a PSW are shown to be equal to those of a continuous waveguide with an averaged Del

The authors present the formulation of a 2-D beam propagation method for weakly guiding 3-D structures. The waveguide itself may have any cross section, provided that the propagating field has a quasi-cylindrical shape. The dimensional reduction is c

In some waveguide materials, strong second-order optical nonlinearity is accompanied by strong harmonic propagation loss, particularly due to absorption. The conversion efficiency of such waveguides can be significantly enhanced by using a distribute

The design of an efficient wide-angle dielectric optical waveguide Y-junction power divider is outlined. The method has several degrees of freedom that can be used to optimize the device's performance to achieve minimization of the radiation loss for
