Cosmological boundary conditions for particles and fields are often discussed as a Cauchy problem, in which configurations and conjugate momenta are specified on an "initial" time slice. But this is not the only way to specify boundary conditions, an

The dynamics of polymers are investigated in the regime of high molecular weight and high concentration using Monte Carlo dynamics. The lattice model used is described, and the idealizations used in this and other models are discussed. The results ar

Gel electrophoresis of DNA has improved greatly in the last decade, mostly owing to the invention of pulsed-field gel electrophoresis (1). This has enabled the separation of DNA more than two orders of magnitude longer than what was previously possib

The behavior of highly stretched chains is not well described by computer simulations using the usual short‐range Monte Carlo algorithms. Results from these have been shown to produce unphysical slowing down due to artificial energy barriers impose

We analyze density fluctuations of a self-avoiding chain in a random environment by a computer simulation. The density at a site is obtained by computing the number of times a monomer visits a particular site on a finite lattice. Although the chain o

Monte Carlo simulations of proteins are hindered by the system's high density which often makes local moves ineffective. Here we devise and test a set of long range moves that work well even when all sites of a lattice simulation are filled. We demon

The author investigated the motion of many non-interacting particles with inertia in a viscous medium subject to an external, random force field that varied both in space and time. By varying parameters in the problem, it was found that there is a tr

We consider iterating functions that consist of the identity map $[f(x)=x]$ plus a random function. The random function in every iteration is different and has a mean value of zero. We investigate the behavior of the entire iterated function. It is d

The motion of a quantum-mechanical particle driven by a random fluctuating force is studied. Dissipation is introduced by coupling the particle to a continuous distribution of harmonic oscillators. A general expression for the mean-square displacemen

The dynamics of a long chain macromolecule in a gel is examined using numerical and analytical approaches. In contrast with previous conjectures, it is found that the chain does not move entirely in a ‘‘tube.’’ For strong fields, an instabili
