The movement of chromosomes that precedes meiosis was observed in living cells of fission yeast by fluorescence microscopy. Further analysis by in situ hybridization revealed that the telomeres remain clustered at the leading end of premeiotic chromosome movement, unlike mitotic chromosome movement in which the centromere leads. Once meiotic chromosome(More)
—Asynchronous cellular arrays have gained attention as promising architectures for nanocomputers, because of their lack of a clock, which facilitates low power designs, and their regular structure, which potentially allows manufacturing techniques based on molecular self-organization. With the increase in integration density comes a decrease in the(More)
Opinions differ widely as to the type of architecture most suitable for achieving the tremendous performance gains expected with computers built by nanotechnology. In this context little research effort has gone into asynchronous cellular arrays, an architecture that is promising for nanocomputers due to (1) its regular structure of locally interconnected(More)
The realization of molecule-based miniature devices with advanced functions requires the development of new and efficient approaches for combining molecular building blocks into desired functional structures, ideally with these structures supported on suitable substrates 1-4. Supramolecular aggregation occurs spontaneously and can lead to controlled(More)
Reversible computation has attracted much attention over the years, not only for its promise for computers with radically reduced power consumption, but also for its importance for Quantum Computing. Though studied extensively in a great variety of synchronous computation models, it is virtually unexplored in an asynchronous framework. Particularly suitable(More)
Asynchronous cellular automata (ACA) are cellular automata that allow cells to update their states independently at random times. Because of the unpredictability of the order of update, computing on ACA is usually done by simulating a timing mechanism to force all cells into synchronicity after which well-established synchronous methods of computation can(More)
