Chromatin structures have to be precisely duplicated during DNA replication to maintain tissue-specific gene expression patterns and specialized domains, such as the centromeres. Chromatin remodeling factors are key components involved in this process and include histone chaperones, histone modifying enzymes and ATP-dependent chromatin remodeling complexes. Several of these factors interact dir...

Mobile ad hoc networks (MANETs) define a challenging computing scenario where access to resources is restrained by connectivity among hosts. Replication offers an opportunity to increase data availability beyond the span of transient connections. Unfortunately, standard replication techniques for wired environments mostly target improvements to fault-tolerance and access time, and in general ar...

In this paper we extend discrete time semi-static trading strategies by also allowing for dynamic in a finite amount of options, and study the consequences model-independent super-replication prices exotic derivatives. These include duality results as well precise characterization pricing rules dynamically tradable options triggering an improvement price bounds derivatives comparison with conve...

Replicating for performance constitutes an important issue in large-scale data management systems. In this context, a significant number of replication strategies have been proposed for data grid systems. Some works classified these strategies into static vs. dynamic or centralised vs. decentralised or client vs. server initiated strategies. Very few works deal with a replication strategy class...

Data replication in distributed databases has been investigated extensively with the hope that it will improve performance, reliability, and availability. However, the growth of the Internet has shown us that current replica management do not work well when the replicas are connected by an unreliable network, subject to congestion and dynamic topology changes. In this paper, we present a replic...

In large systems, data management is only possible through the use of replication techniques. In order to improve availability and ensure fast and efficient access, we propose in this paper a dynamic replication algorithm which takes into account also the placement of data in a hierarchical data grid. Experimental results show the effectiveness of our approach in terms of response time and avai...

As grow as the data-intensive applications in cloud computing day after day, data popularity in this environment becomes critical and important. Hence to improve data availability and efficient accesses to popular data, replication algorithms are now widely used in distributed systems. However, most of them only replicate the static number of replicas on some requested chosen sites and it is ob...

Cloud computing has been a huge-scale parallel with shared computing system. It comprises an accumulation of inter-related plus virtualized calculating resources which are managed to be one or more amalgamated calculating resources. The target of the survey is a mechanized evaluation or else explanation of proceeding events in cloud data replication system. Completely, 34 papers are accumulated...

SRC kinases and PKR are intracellular protein kinases, which play key roles in intracellular viral replication. In this research, the effect of SRC kinase inhibition and PKR activation and inhibition on replication of coxsakievirus (CVB3), an entrovirus of the family picornaviridae – causative agents of fatal myocarditis, was studied. Vero and Hela cells were cultured and infected with CVB3 in ...
