The Physicist and His Patents

Categories for the practising physicist

In this chapter we survey some particular topics in category theory in a somewhat unconventional manner. Our main focus will be on monoidal categories, mainly symmetric ones, for which we propose a physical interpretation. Special attention is given to the category of sets and relations, posetal categories, diagrammatic calculi, strictification, compact categories, biproduct categories and abst...

Editorial: Radiological Emergencies and the Medical Physicist

The events at the Fukushima Daiichi nuclear power plant in Japan prompted an editorial(1) written by Bill Hendee, PhD, Editor-in-Chief of Medical Physics, in which he discussed the role of medical physicists as potential volunteers in responding to public health emergencies, especially radiological emergencies of various types. In order to obtain more widespread dissemination of this informatio...

Radiological Emergencies and the Medical Physicist

The widespread damage and loss of life caused by the March 11th earthquake-generated tsunami in Japan, and the resulting emergency at the Fukushima Daiichi nuclear power facility, raise once again the question of the role of knowledgeable civilians in responding to public health emergencies. In the case of a radiological emergency, medical physicists are among the more knowledgeable individuals...

Patient safety and the medical physicist.

Overexposures in computed tomography: In several institutions, overexposures have occurred during use of x-ray computed tomography (CT) for brain perfusion studies to identify 10 the neurological consequences of strokes and other events. In some cases, patients received exposures that were several times greater than necessary. The overexposures were caused by use of inappropriate CT protocols f...
