چکیده
A number of exact results have been obtained recently for the one-dimensional asymmetric simple exclusion process, a model of particles which hop to their right at random times, on a one-dimensional lattice, provided that the target site is empty. Using either a matrix form for the steady-state weights or the Bethe ansatz, several steady-state properties can be calculated exactly: the current, the density profile for open boundary conditions, the diffusion constant of a tagged particle. The matrix form of the steady state can be extended to calculate exactly the steady state of systems of two species of particles and shock profiles. ( 1998 Elsevier Science B.V. All rights reserved.

Dynamic Fitness Landscapes in Molecular Evolution
We study self-replicating molecules under externally varying conditions. Changing conditions such as temperature variations and/or alterations in the environment’s resource composition lead to both non-constant replication and decay rates of the molecules. In general, therefore, molecular evolution takes place in a dynamic rather than a static fitness landscape. We incorporate dynamic replicati...
متن کاملTechniques of replica symmetry breaking and the storage problem of the McCulloch-Pitts neuron
In this article the framework for Parisi's spontaneous replica symmetry breaking is reviewed, and subsequently applied to the example of the statistical mechanical description of the storage properties of a McCulloch-Pitts neuron. The technical details are reviewed extensively, with regard to the wide range of systems where the method may be applied. Parisi's partial differential equation and r...
متن کاملDrosophila development: The secrets of delayed induction
Dorsoventral axis formation in Drosophila relies on extracellular signals which are generated only at the ventral side of the egg. This asymmetry, in turn, depends on the expression specifically in ventral follicle cells of pipe, the product of which seems likely to be a glycosaminoglycan-modifying enzyme.
متن کاملProbabilities on Lukasiewicz-Moisil algebras
We define a concept of probability on an n-valued Lukasiewicz-Moisil algebra and we present some basic properties. The main result is an extension theorem for continuous probabilities, which is already known for probabilities defined on Boolean algebras and MV-algebras. © 1998 Elsevier Science Inc.

متن کاملCliques and clustering: A combinatorial approach
Submitted Abstract We use column generation and a specialized branching technique for solving constrained clustering problems. We also develop and implement an innovative com-binatorial method for solving the pricing subproblems. Computational experiments comparing the resulting branch-and-price method to competing methodologies in the literature are presented and suggest that our technique yie...
