Assessing the Big Five personality traits using real-life static facial images.

There is ample evidence that morphological and social cues in a human face provide signals of human personality and behaviour. Previous studies have discovered associations between the features of artificial composite facial images and attributions of personality traits by human experts. We present new findings demonstrating the statistically significant prediction of a wider set of personality features (all the Big Five personality traits) for both men and women using real-life static facial images.

Spatial resolution improvement for an optical transition radiation monitor by asymmetric light collection.

The applicability of optical transition radiation (OTR) for measurements of micron sized transverse electron beam profiles is limited not only by the optical system resolution which has a fundamental limit imposed by the uncertainty principle. In the case of OTR generation, a single electron crossing the boundary between vacuum and screen cannot be considered as a single emitting point with isotropic angular distribution. On the contrary, the radiation is emitted from an area with a transverse range that is defined by the radial extension of the electron's Lorentz contracted Coulomb field and is typically estimated as γλ (with γ the Lorentz factor and λ the wavelength of observation).

Progressive Scoliosis and Syringomyelia - Questions of Surgical Approach.

Background: The rate of scoliosis in syringomyelia patients ranges from 25 to 74.4%. In turn, syringomyelia occurs in 1.

[Neuromediator systems in some brain regions of rats subjected to morphine intoxication].

The content of neuromediators and its metabolites in the cortex of cerebral hemispheres, in thalamus and brain stem was studied under chronic morphine intoxication (7-21 days). The morphine intake during 7-14 days was accompanied by changes of catecholamine system functioning, which was the most pronounced in the thalamus and the brain stem. These changes included increased secretion of dophamine and noradrenaline, their decrease in the brain tissue, and the increased content of their metabolites.

Neurotransmitter mechanisms of morphine withdrawal syndrome.

Activity of the major neurotransmitter systems in the brainstem and cerebellum was studied in rats with morphine withdrawal syndrome. The most significant changes were found in the brainstem of animals by the 36th hour and 7 days after morphine withdrawal. Dysfunction was revealed in the dopaminergic, noradrenergic, and serotoninergic neurotransmitter systems.
