We report an approach for fabricating biomimetic surface replicas of cells with nanoscale resolution. Fixed cells serve as a template for a two-stage replica molding process. Cast from the template, the impression replica contains a reproduction of cellular topographical features indented into its surface, and cast from the impression replica, the relief replica contains a copy of these feature...

Data grid is developed to facilitate sharing data and resources located in different parts of the world. The major barrier to support fast data access in a data grid is the high latency of wide area networks and the Internet. Data replication is adopted to improve data access performance. When different sites hold replicas, there are significant benefits while selecting the best replica. In thi...

Due to high latency of the Internet, it becomes a challenge to access large and widely distributed data quickly and efficiently on data grids. Replication is a process to address this issue, by storing data in different locations to reduce access latency and improve data locality. However, because of the limited storage capacity, a good replica replacement algorithm is needed to improve the eff...

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...
