We present a phenomenological replica-field theory for symmetric AB copolymer systems with the A.block near its glass transition point. Using a variational principle based on the second Legendre transformation we prove that the interaction between composition fluctuations, due to the loss mobility of the A monomers, results in the elimination of microphase separation. Instead of a microphase se...

An asynchronous implementation of the replica exchange method that addresses some of the limitations of conventional synchronous replica exchange implementations is presented. In asynchronous replica exchange pairs of processors initiate and perform temperature replica exchanges independently from the other processors, thereby removing the need for processor synchronization found in conventiona...

A mechanical method for efficient replication of DNA microarrays is described. The approach consists of three steps. First, a master DNA microarray consisting of single-stranded DNA elements is exposed to a solution containing the biotin-functionalized complement of each array element. Following hybridization, a replica surface modified with streptavidin is brought into contact with the master....

The success of a Web service is largely dependent on its responsiveness (i.e., its availability and timeliness) in the delivery of the information its users (clients) require. A practical approach to the provision of responsive Web services is based on introducing redundancy in the service by replicating the service itself across a number of servers geographically distributed over the Internet....

Cloud data storage platforms have attracted increasing attention in data management. Data replication is a well-known technique that reduces access latency, thus improving cloud data storage availability and performance. Nonetheless, replica placement algorithms are among the significant issues in data replication, which affect data availability and access performance considerably. Replica plac...

Replica management is basic and challenging issue for distributed storage system designer. The objective of this paper is to dynamically create, migrate and delete replicas among nodes in response to changes in the access patterns. This paper presents an Adaptive Replica Management Model for large-scale Object-based Storage Devices (OSDs). The model expresses availability and consistency mainte...
