,Local Area Networks — A Survey, “conventional” LAN architectures, Ethernet and Token-Ring, will be given together with some examples of possible topologies and infrastructures. Then some of the principles and highlights of the relatively new FDDI (Fiber Distributed Data Interface) high-speed LAN will be reported. Finally existing

Fast Access to Supercomputer Applications,g a variety of supercomputers, mainframes or workstations. Typical network topologies and installation profiles are shown, and one example of a distributed application in the field of chemistry is mentioned. Finally, trends in the rapidly growing network market are analyzed.

Long Time Dynamics of Proteins: an off-Lattice Monte Carlo Method,The only molecular degrees of freedom considered are bond rotations. All other degrees of freedom including the amide plane torsions are kept rigid. These constraints can approximately account for all interactions related to the chemical bonding. To provide a first test of the method, the non-bonded
