Determination of the Time-frequency Features for Impulse Components in EEG Signals.
Neuroinformatics

Institute of Mathematics, University of Kassel, Heinrich-Plett-Str. 40, Kassel, 34132, Germany.
Accurately identifying the timing and frequency characteristics of impulse components in EEG signals is essential but limited by the Heisenberg uncertainty principle. Inspired by the visual system's ability to identify objects and their locations, we propose a new method that integrates a visual system model with wavelet analysis to calculate both time and frequency features of local impulses in EEG signals. We develop a mathematical model based on invariant pattern recognition by the visual system, combined with wavelet analysis using Krawtchouk functions as the mother wavelet.

Blink-related oscillations (BROs) are newly discovered neurophysiological brainwave responses associated with spontaneous blinking, and represent environmental monitoring and awareness processes as the brain evaluates new visual information appearing after eye re-opening. BRO responses have been demonstrated in healthy young adults across multiple task states and are modulated by both task and environmental factors, but little is known about this phenomenon in aging. To address this, we undertook the first large-scale evaluation of BRO responses in healthy aging using the Cambridge Centre for Aging and Neuroscience (Cam-CAN) repository, which contains magnetoencephalography (MEG) data from a large sample ( = 457) of healthy adults across a broad age range (18-88) during the performance of a simple target detection task.

A recruiting rate () of 0.1-5 s has been proposed as the criterion for super-resolution spontaneously blinking rhodamines. Accurate prediction of the recruiting rate () of rhodamines is very important for developing spontaneously blinking rhodamines.

Optometry and Vision Science Research Group, School of Optometry, Aston University, Birmingham, United Kingdom.
Significance: Evaporative dry eye disease, due to meibomian gland dysfunction, causes significant suffering for millions of people globally, yet satisfactory long-term treatment remains elusive for many. Investigation of potential therapies for meibomian gland dysfunction is therefore of high importance to clinicians and their patients.
Purpose: This study aimed to compare the efficacy of a new device for meibomian gland debridement and expression to that of the conventional way of providing this treatment.
