Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Method for compensating the constant component of noise in the reflectogram of a fiber-optic communication line under conditions of insufficient dynamic range of an optical backscatter reflectometer in the time domain

open access: yesНаучно-технический вестник информационных технологий, механики и оптики
A method for compensating for the constant noise component of reflectograms for a coherent optical backscatter reflectometer in the time domain is proposed. The presented solution ensures correct visualization of reflectograms, improves their readability

The Onset Threshold of Cybersickness in Constant and Accelerating Optical Flow

open access: yesApplied Sciences, 2020
This study investigated the principal translational or rotational axis that evokes the most severe cybersickness by detecting constant velocity and acceleration thresholds on the onset of cybersickness.

High Verdet Constant Ga:s:la:o Chalcogenide Glasses For Magneto-optical Devices [PDF]

open access: yes, 2015
The magneto-optical rotation at room temperature was measured for three Ga:S:La:O chalcogenide glasses at several laser lines in the visible. The first sample was a binary system constituted by 70 mol % Ga2S3 and 30 mol % La2O3, whereas in the second and

Dynamic circulating-loop methods for transmission experiments in optically transparent networks [PDF]

open access: yes, 2008
Recent experiments incorporating multiple fast switching elements and automated system configuration in a circulating loop apparatus have enabled the study of aspects of long-haul WDM transmission unique to optically transparent networks.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Thin bonding wires temperature measurement using optical fiber sensors

open access: yes, 2011
In this work we demonstrate the use of optical fiber sensors to measure temperature in thin metallic bonding wires. Temperature was measured in copper wires with diameter of 0.10, 0.28, 0.60 and 0.70 mm and for different values of the driven electrical ...

A theoretical comparison between interferometric and optical beam deflection technique for the measurement of cantilever displacement in AFM [PDF]

open access: yes, 1992
A shot-noise- and diffraction-limited Michelson interferometer and two optical beam deflection configurations are compared for application in an atomic force microscope. The results show that under optimal conditions the optical beam deflection method is

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Optical Constants and Optical Anisotropy of Ultrathin Gold Films

open access: yesAdvanced Photonics Research, 2023
Continuous and homogeneous thin gold films are fabricated on Si–SiO2 substrates using an additional seed layer based on Cu oxide or oxidized Cu. The optical properties of these gold films with thicknesses from 3 to 50 nm are studied with the help of variable angle spectroscopic ellipsometry. The optical constants and the dielectric functions of thin Au
