Au-Hyperdoped Si Nanolayer: Laser Processing Techniques and Corresponding Material Properties.

The absorption of light in the near-infrared region of the electromagnetic spectrum by Au-hyperdoped Si has been observed. While silicon photodetectors in this range are currently being produced, their efficiency is low. Here, using the nanosecond and picosecond laser hyperdoping of thin amorphous Si films, their compositional (energy-dispersion X-ray spectroscopy), chemical (X-ray photoelectron spectroscopy), structural (Raman spectroscopy) and IR spectroscopic characterization, we comparatively demonstrated a few promising regimes of laser-based silicon hyperdoping with gold.

Reconstructing the Spatial Parameters of a Laser Beam Using the Transport-of-Intensity Equation.

A simple method for reconstructing the spatial parameters of a laser beam, based on the transport-of-intensity equation, is presented. Registration of cross-section intensity distributions in several planes was carried out using a single CMOS camera. The processing of the experimental measurements with the help of specialized software helped to reconstruct all of the spatial parameters, namely, the radius and position of the waist, Rayleigh length, angular divergence, quality parameter M2 The method was compared with measurements made according to the international standard ISO 11146 and showed that the difference in the spatial parameters is 10% or less, which shows good agreement.

Arginine vasopressin 1a receptor RS3 promoter microsatellites in schizophrenia: a study of the effect of the "risk" allele on clinical symptoms and facial affect recognition.

We studied AVPR1A RS3 polymorphism in schizophrenic patients and controls. AVPR1A RS3 was not associated with schizophrenia. The allele 327bp implicated in autism and social behavior was associated with negative symptoms and tended to be linked to patient facial affect recognition suggesting its impact on schizophrenia social phenotypes.

[Association of the insulin-like growth factor II (IGF2) gene with human cognitive functions].

Active search for candidate genes whose polymorphisms are associated with human cognitive functions has been in progress in the past years. The study focused on the role that the insulin-like growth factor II (IGF2) gene may play in the variation of cognitive processes related to executive functions. The ApaI polymorphism of the IGF2 gene was tested for association with selective attention during visual search, working memory/mental control, and semantic verbal fluency in a group of 182 healthy individuals.
