2. Particle swarm optimization in WDM/OCDM networks with physical impairments
In this paper, optimization procedures based on particle swarm optimization (PSO) are investigated, aiming to efficiently solve the optimal resource allocation for signal-to-noise plus interference ratio (SNIR) optimization of optical code paths (OCPs) from wavelength division multiplexing/optical code division multiplexing (WDM/OCDM) considering imperfectio

5. An unusual extraocular muscle anomaly in a patient with Crouzon's disease.
A 29-year-old female suffering from Crouzon's disease was admitted to hospital with retinal detachment in the right eye. At operation agenesis of 4 extraocular muscles (superior and inferior recti and obliquus) was found, together with abnormal insertion of the 2 horizontal muscles. The same extraocular muscular abnormalities were found in the left eye. We s

6. A novel theoretical approach to the analysis of dendritic transients.
A novel theoretical framework for analyzing dendritic transients is introduced. This approach, called the method of moments, is an extension of Rall's cable theory for dendrites. It provides analytic investigation of voltage attenuation, signal delay, and synchronization problems in passive dendritic trees. In this method, the various moments of a transient

7. Bell's phenomenon in newborns and premature babies.
AIMS--To evaluate the development and course of Bell's phenomenon (BP) in premature and normal neonates. METHODS--Twenty seven preterm infants and 42 healthy full term infants were studied. Mean birth weight, gestational age, and head circumference were recorded. BP was graded from no response to full response. The premature group was examined in the first w
