R&II, in his book on " Untersuchungen tiber den Phototropismus der Tiere, " says concerning the ephemeridz: Ii They react very sharply to a gentle current of air, turning… (More)
This paper presents a way to use an unreliable transport protocol to perform distributed OpenGL visualization on a commodity network of computers. We present a performance evaluation of a prototype implementation based on the Chromium environment.
The data-parallel programming model is now widely recognized as fundamental for high performance computing in massively parallel machines. Amazingly, much eeort has be done on designing data-parallel languages and developing compilers for them, but little attention has been paid to the precise semantic deenition of these languages, and to the formal… (More)
The average branchial blood pressure in sand sharks was 32 mm. of mercury. The highest recorded in a resting animal was 43 mm. The average dorsal or systemic pressure was 23.3 mm.; highest 30 mm. The ratio of branchial to systemic pressure is about 3 to 2. The pressure in both systems keeps up well under trauma; but under experimental conditions, with or… (More)
One of the aims of this workshop was to present basic notions from random matrix theory, with a particular focus on providing background material so that all participants can interact successfully with more experienced and senior researchers involved in the program. Many of the senior participants are experts in one area of random matrix theory and have… (More)
Several monoclonal antibodies (mAb) reactive against a high-molecular-weight growth factor from human glioblastoma cell lines have been produced by immunizing mice with partially purified preparations from conditioned media. Antibody-secreting colonies were selected by their capacity to bind 35S-labeled glioma cell protein and by reactivity in indirect… (More)
