Instead, DNA paternity testing has generated mountains of litigation, as biological proof has been challenged by the argument that paternit...

The shadows leave a doubt--the angiographic recognition of vulnerable coronary artery plaques.

Coronary angiography provides detailed, dynamic images of the coronary arterial lumens. These images provide an explanation for angina and a roadmap to direct surgical or catheter-based revascularization. Although a patient’s prognosis is influenced by left ventricular systolic performance and the number of stenosed coronary vessels, analysis of stenosis severity alone does not accurately ident...

We investigate the brightness distribution in and around outdoor shadows (for a variety of sky conditions) using modeling and field measurements. The dominant factor influencing the brightness of a shadow is the solid angle subtended by the object blocking the Sun. Occulters at the zenith that subtend a small solid angle cast shadows that are bright and possess a nearly uniform brightness acros...
