Antihypertensive drug treatment is capable of aggravating angina pectoris in hypertensive patients with coronary artery disease. The complication appears to be due to different hemodynamic mechanisms. Angina pectoris caused by hydralazine may result not only from a reduction in aortic perfusion pressure but also from increases in cardiac output and pulse rate which the drug produces. Coronary i...

We propose novel gaze control algorithms for active perception in mobile autonomous agents with directable, foveated vision sensors. Our agents are realistic artificial animals, or animats, situated in physics-based virtual worlds. Their active perception systems continuously analyze photorealistic retinal image streams to glean information useful for controlling the animat ’ s eyes and body. T...
