To achieve better scalability in a fully replicated distributed main-memory database, we propose support for virtual full replication [6]. Full replication is often used to improve availability and predictability in distributed real-time applications. In a fully replicated database all updates are sent to all nodes regardless of where the data is going to be used there or not. In a fully replic...

In a vehicular edge computing (VEC) system, vehicles can share their surplus computation resources to provide cloud services. The highly dynamic environment of the network makes it challenging guarantee task offloading delay. To this end, we introduce replication VEC where replicas are offloaded multiple at same time, and is completed upon first response among replicas. First, impact number on ...

Replication strategy is used to minimize the recovery time and data loss at an operational system and it attempts to reduce the system load, access latency and network congestion in a distributed system. Replication improves the reliability and scalability of the services. To increase availability we divide large files into small, medium and large fragments. When there are more number of hits f...

Five distinct patterns of DNA replication have been identified during S-phase in asynchronous and synchronous cultures of mammalian cells by conventional fluorescence microscopy, confocal laser scanning microscopy, and immunoelectron microscopy. During early S-phase, replicating DNA (as identified by 5-bromodeoxyuridine incorporation) appears to be distributed at sites throughout the nucleoplas...

The publication of the pivotal state machine replication protocol PBFT laid foundation for a body BFT protocols. We introduce probabilistic model evaluating protocols in presence dynamic link and crash failures. is derived from communication pattern, facilitating an adaptation to other replicas captured used derive success probability execution. To this end, we examine influence failure rates a...

In this paper, we propose a file replication method to achieve load balancing in terms of write access to storage device (“write storage access load balancing” for short) in unstructured peer-to-peer (P2P) file-sharing networks in which the popularity trend of queried files varies dynamically. The proposed method uses a write storage access ratio as a load balance index value in order to stabil...

Visualization of topoisomerases in live Bacillus subtilis cells showed that Topo I, Topo IV, and DNA gyrase differentially localize on the nucleoids but are absent at cytosolic spaces surrounding the nucleoids, suggesting that these topoisomerases interact with many regions of the chromosome. While both subunits of Topo IV were uniformly distributed throughout the nucleoids, Topo I and gyrase f...

objective: the brucella melitensis virb operon, encoding a type iv secretion system (t4ss), is required for intracellular replication and persistent infection in the mouse model. the product of the second gene of the virb operon, virb2, is predicted to be localized at the bacterial surface, where they could potentially interact with host cells. studies to date have focused on characterization o...

DNA replication is one of the most important events in living cells, and it is still a key problem how the DNA replication machinery works in its details. A replication fork has to be a very dynamic apparatus since frequent DNA polymerase switches from the initiating DNA polymerase alpha to the processive elongating DNA polymerase delta occur at the leading strand (about 8 x 10(4) fold on both ...

Nucleosomes provide additional regulatory mechanisms to transcription and DNA replication by mediating the access of proteins to DNA. During the cell cycle chromatin undergoes several conformational changes, however the functional significance of these changes to cellular processes are largely unexplored. Here, we present the first comprehensive genome-wide study of nucleosome plasticity at sin...
