models are especially useful for analyzing the control of dataflow in multiprocessor computers. They are supported by software tools such as Dijkstra's P and V primitives and semaphores5 and Conway's FORK and JOIN mechanisms. 6 These, and other tools, 7-9 provide means for scheduling and synchronizing tasks and resolving conflicts among processors in asynchronous parallel computer systems. On t...

This paper describes a test structure consisting of a ring oscillator and an inverter chain. The load of the elements of the ring oscillator and the inverter chain is programmable. The propagationdelay times measured give a better correlation with real logic circuits. Introduction A test structure often used for the characterization of the circuit performance,in a particular process is the ring...

Eighteen overlapping cosmid clones spanning 240 kilobases and encoding the gene for factor B and two genes related to the fourth component of complement (C4) were isolated from a murine H-2d genomic library. Cosmid clones were identified by hybridization to human cDNA probes for factor B and C4 and were linked by chromosomal walking procedures. The cluster of clones contains two regions with se...

The expression “chemigram” is attributed to Pierre Cordier (1958) [1]. The term generally refers to the use of black and white photochemistry to create abstract images on black and white photographic papers in subdued room light. Colours in the images are usually, though not exclusively, generated due to complex oxidation-reduction byproducts and local physical development effects. This paper d...

The conserved TPLH tetrapeptide motif of ankyrin repeats (ARs) plays an important role in stabilizing AR proteins, and histidine (TPLH) to arginine (TPLR) mutations in this motif have been associated with a hereditary human anemia, spherocytosis (HS). Here, we used a combination of Atomic Force Microscopy (AFM)-based single-molecule force spectroscopy and molecular dynamics (MD) simulations to ...
