The success of multi-processor systems depends to a large extent on the underlying memory coherence system. In large systems, this can quickly become exponentially complicated. This in turn leads to increasie in development as well as debugging time. As the size of the system increases so do the chances of bugs slipping through the debugging process and into the hands of consumers. One way to d...

The author presents a simplified technique for midline screw-plate fixation in fusion procedures after anterior cervical discectomy, in which the plate is introduced over the Caspar distractor pins. The Uniplate system used, with a single screw in each vertebral body, minimizes bone damage to the vertebral body as the screws can be fixed in the holes previously used for the Caspar distractor pi...

OBJECTIVE To observe the accuracy of femoral preparation and the position of the cementless prosthesis in femoral cavity, and to compare the results between the computer-assisted surgical group (CASPAR) and the conventional group. METHODS Ten femoral components were implanted either manually or by CASPAR in cadaver femurs. The specimens were cut to 3 mm thick slices. Microradiograms of every ...

for very helpful discussions and valuable suggestions, and Emma Caspar for editorial assistance.

Accurate staging of cancer underpins the decision making for individual patients, the collection of outcomes data and the development of appropriate services. Unfortunately, this is not something that the wider oncology community has done well and there are many valid reasons why this part of cancer patient management has proved challenging. However, there are ways in which Clinical Radiologist...

On January 10 and 11, 1997, a two-day symposium titled Quasi-Equivalence: Motion and Adaptability in Living Molecules was held at Florida State University on the occasion of the 70th birthday of Dr. Donald L. D. Caspar. This issue of the Biophysical Journal contains articles presented at that symposium in recognition of the contributions that Dr. Caspar has made to our understanding of the stru...

OBJECTIVES Psoriatic arthritis (PsA) has been defined as a systemic, chronic, inflammatory arthritis, usually seronegative for rheumatoid factor (RF), associated with cutaneous psoriasis. The exact prevalence of PsA is unknown and its estimation has been difficult, partly due to the lack of a widely accepted classification criteria. Agreed and validated criteria will facilitate comparison betwe...

DURING a review of the aetiology of intlammation and cysts of Bartholin’s glands, interest was aroused in the discoverer of these glands. This led to a search of the literature and the tracing out of the history of a remarkable family of Danes, who flourished in the 17th and 18th centuries. The first of the line of medical interest was Caspar Bartholinus who lived from 1585 to 1629. He was born...
