Automatic calcium scoring in low-dose chest CT using deep neural networks with dilated convolutions
, 2018 Heavy smokers undergoing screening with low-dose chest CT are affected by cardiovascular disease as much as by lung cancer. Low-dose chest CT scans acquired in screening enable quantification of atherosclerotic calcifications and thus enable ...

On the Dose Coefficient of Uranium Hexafluoride
Medical Radiology and radiation safety, 2021 Introduction: Uranium hexafluoride (UF6, UHF) is a gaseous product containing uranium and fluorine. Once in the air, it interacts with water vapor and produces hydrolysis products that can penetrate the human body and lead to the chemical effects of uranium and fluorine, as well as the radiation effects of uranium on the body.

Hill coefficients, dose–response curves and allosteric mechanisms [PDF]
Journal of Chemical Biology, 2009 Hill coefficients (n(H)) derived from four parameter logistic fits to dose-response curves were compared to calculated realistic reaction schemes and related to experimental data: (1) Hill coefficients may give information on the number of interacting sites but cannot distinguish between competitive, non-competitive or ortho-, iso-, or allosteric ...

A theoretical framework for estimation of AUCs in complete and incomplete sampling designs. [PDF]
, 2009 Nonclinical in vivo animal studies have to be completed before starting clinical studies of the pharmacokinetic behavior of a drug in humans. The drug exposure in animal studies is often measured by the area under the concentration versus time curve (AUC)

Personal dose-equivalent conversion coefficients for 1252 radionuclides [PDF]
Radiation Protection Dosimetry, 2014 Dose conversion coefficients for radionuclides are useful for routine calculations in radiation protection in industry, medicine and research. They give a simple and often sufficient estimate of dose rates during production, handling and storage of radionuclide sources, based solely on the source's activity.
