We discuss cellular automata (CA) architectural considerations that led to the design of the cam-8 CA machine; describe some of the spatial modeling tasks that CA's have been applied to on this machine; and discuss some of the interesting practical and theoretical modeling challenges that remain.

IN a short article in the British Medical Journal last year, a general practitioner recorded that one day the local postman said to him: "Doctor, most of those who pass away round here are patients of yours." It would certainly be true to say that many of those who have passed away in the Belmont area of Belfast during the past forty years were patients of mine, and this is a matter of mingled ...

We discuss the instrumental factors which constrain the sensitivity limits of the mid-infrared camera (ISOCAM) of ESA's Infrared Space Observatory (ISO). The observing strategy judged to be best suited to faint-source detection is described. A data analysis technique adapted to the extraction of the faintest point-sources is discussed. We report the application of these techniques to an extreme...

OBJECTIVE This paper will explore ultimate frisbee injuries. METHOD This study uses an anonymous, retrospective, self-reported survey of 135 adult athletes at a Midwestern ultimate frisbee tournament. Subjects were queried regarding injuries to specific body parts, those causing missed activity, recurring injuries, medical care sought, basic demographic data, duration of participation, handed...

The present status of the nominal LHC beam in the LHC injector complex and the limitations towards the achievement of the ultimate brightness are outlined.
