Examination for Practical Use in Dual Energy Gamma-ray Transmission Techniques. Application to Grading of Gold Alloys.

RADIOISOTOPES, 1995
For practical use of dual energy gamma-ray transmission techniques in various fields, necessary conditions have been examined experimentally.The study revealed the necessary conditions shown in the following : (1) the shape and size of the collimator aperture for a gamma-ray beam must be changed according to those of a sample to be measured, (2) a ...

Comparison of Gamma Sources (Cobalt and Cesium) for Density Measurement of Metals and Alloys via Using Transmission Technique

Journal of Engineering Technology and Applied Sciences, 2021
One of the solutions for density measurement is to make use of gamma-ray transmission technique. We studied by this technique, using by Co-60 and Cs-137. Each source, without materials in geometry, was counted and noted intensities as (I0). All materials were counted and noted intensities as (I). [I/I0] rates were calculated.

Increasing Brain Gamma Activity Improves Episodic Memory and Restores Cholinergic Dysfunction in Alzheimer's Disease

Annals of Neurology, 2022
This study aimed to assess whether non‐invasive brain stimulation with transcranial alternating current stimulation at gamma‐frequency (γ‐tACS) applied over the precuneus can improve episodic memory and modulate cholinergic transmission by modulating ...

Interneuronal GluK1 kainate receptors control maturation of GABAergic transmission and network synchrony in the hippocampus

Molecular Brain, 2023
Kainate type glutamate receptors (KARs) are strongly expressed in GABAergic interneurons and have the capability of modulating their functions via ionotropic and G-protein coupled mechanisms.

Gamma oscillation plasticity is mediated via parvalbumin interneurons

Science Advances
Understanding the plasticity of neuronal networks is an emerging field of (patho-) physiological research, yet the underlying cellular mechanisms remain poorly understood. Gamma oscillations (30 to 80 hertz), a biomarker of cognitive performance, require

Prevalence and Transmission of Beta and Gamma Human Papillomavirus in Heterosexual Couples

Open Forum Infectious Diseases, 2017
Background Beta (β) and gamma (γ) human papillomavirus (HPV) are commonly found on the skin. Few of the β types are associated with nonmelanoma skin cancer.

A computational study on altered theta-gamma coupling during learning and phase coding [PDF]

, 2012
There is considerable interest in the role of coupling between theta and gamma oscillations in the brain in the context of learning and memory. Here we have used a neural network model which is capable of producing coupling of theta phase to gamma ...
