Transistor Counting Systems for Scintillation Detectors [PDF]

IRE Transactions on Nuclear Science, 1960
The requirements for multiple-coincidence counting systems with 10-8 to 10-9. sec time resolution can be met economically with presently available high-frequency transistors. The design of solid-state coincidence circuits, amplitude discriminators, and decade scalers is considered and their operation discussed.

All‐Inorganic Cesium Zinc Halides as Ultra‐Stable Lead‐Free Perovskite Electrodes for Li‐Ion Batteries

Advanced Electronic Materials, EarlyView.
Here we explore the use of lead‐free metal halide perovskites in lithium ion batteries. Cesium zinc chloride and bromide both show reasonable discharge capacities and high stability compared to lead based perovskites. ABSTRACT Halide perovskites have recently gained attention for use as electrode materials in lithium‐ion batteries. However, lead halide

Guided Sample Pooling in Human Mass Balance Studies: A Recommended Strategic Decision Framework

Clinical Pharmacology &Therapeutics, EarlyView.
Radiolabeled human mass balance studies are crucial for identifying circulating metabolites and understanding drug absorption, excretion, and clearance pathways. Metabolite profiling involves quantifying all drug‐related entities, including parent drug and metabolites in plasma and excreta, using extended liquid chromatography methods coupled with ...

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...
