Monoclonal antibodies (McAbs) against the myosin heavy chain (MHC) of adult chicken pectoralis muscle have been tested for reactivity with pectoralis myosin at selected stages of chick development in vivo and in vitro. Three such McAbs, MF 20 and MF 14, which bind to light meromyosin, and MF 30, which binds to myosin subfragment two (S2), were used to assay(More)

Acetylcholine receptors (AChR) are organized in a discrete and predictable fashion in the postsynaptic regions of vertebrate skeletal muscle. When muscle is damaged, nerves and myofibers including muscular elements of the endplate degenerate, but the connective tissue elements survive. Muscle fibers regenerate within the basal lamina of the original(More)

This paper describes the network architecture of the Thinking Machines CM-5, a massively parallel MIMD supercomputer. An empirical analysis of the CM-5's performance is quantitatively given and compared to the vendor's speciications. The performance is partitioned into three subsystems of the machine; the fat-tree data network, the vector units, and the(More)
modeling approach explicitly recognizing that many processes are common to predictions across time scales. T he global coupled atmosphere–ocean– land–cryosphere system exhibits a wide range of physical and dynami-cal phenomena with associated physical, biological, and chemical feedbacks that collectively result in a continuum of temporal and spatial(More)
The graph abstraction provides a natural way to represent relationships among complex fast-growing scientific data sets. Graph algorithms are hard to parallelize, making their performance suboptimal on high-performance architectures. Many graph computations, however, contain sufficient parallelism that can be uncovered by using the right primitives. This(More)
