Abstract Background: Many schizophrenic patients are engaged in self-medication drug abuse, including narcotics. It is assumed that many of these patients have a greater number of psychotic symptoms, and show noncompliance with treatment. In this study, we investigated relationship of positive and negative symptoms and opioid dependence in these patients. Methods: This was a descriptive...

We have performed classical and quantum calculations for a hydrogen atom in a strong magnetic field exposed to a parallel electric field that linearly increases with time. The calculations were performed for the situation where the electron is launched from near the nucleus and for a microcanonical ensemble. For the case of low angular momentum, the classical and quantum calculations are compar...

Introduction/Objective. The objective of the study was to determine difference in peripapillary retinal nerve fiber layer (RNFL) thickness patients with open-angle glaucoma (POAG) comparison healthy population and according progression disease. Methods. Four groups were formed among 120 patients: group without glaucoma, early, moderate POAG, preperimetric group. Visual field optical coherent to...

Using the relativistic impulse approximation with empirical NN scattering amplitude and the nuclear scalar and vector densities from the relativistic mean-field theory, we have evaluated the Dirac optical potential for neutrons and protons in asymmetric nuclear matter for different parameter sets NL3, Z27v, and HA [1]. From the resulting Schrodinger-equivalent potential, the high energy behavio...

A~SZFUCZ In this paper a CMOS highly linear current attenuator is described. The circuit is suited for both differential and single input currents. The current gain is electronically variable between -1 and +1 by means of two controlling currents. A simple additional circuit is described to obtain a gain that is linearly dependent on a single control current. Then the circuit can be used as a f...

Many species exhibit dispersal processes with positive density- dependence. We model this behavior using an integrodifference equation where the individual dispersal probability is a monotone increasing function of local density. We investigate how this dispersal probability affects the spreading speed of a single population and its ability to persist in fragmented habitats. We demonstrate that...
