STUDY DESIGN An in vitro biomechanical study. OBJECTIVES The objectives were to: quantify dynamic canal pinch diameter (CPD) narrowing during simulated bilateral facet dislocation of a cervical functional spinal unit model with muscle force replication, determine if peak dynamic CPD narrowing exceeded that observed post-trauma, and evaluate dynamic cord compression. SUMMARY OF BACKGROUND DA...

Abstract: In Grid-based collaborations, a number of data sharing services in Grid are established to provide a unified platform for dynamic discovery, access and replication of distributed data. Controlling access to Grid data in these services requires the ability to dynamically make authorisation decisions based on the data owners’ policies and users’ credentials across administrative domains...

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 next generation of high energy physics experiments, such as the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research, pose a challenge to current data handling methodologies, where data tends to be centralised in a single location. Data grids, including the LHC Computing Grid (LCG), are being developed to meet this challenge by unifying computing and storage r...

Secret distribution and erasure convention based approaches have been used in distributed storage systems to provide the confidentiality, integrity, and availability of critical information. To achieve performance goals in data accesses, these data fragmentation approaches can be combined with dynamic replication. In this paper, we consider data partitioning (both secret distribution and erasur...

This paper presents a meta protocol that allows the dynamic replacement of replication control protocols in replicated databases. The meta protocol is motivated by the diversity of concurrency control and replication control protocols that implement different transaction isolation levels. The replacement of protocols allows applications to dynamically adapt themselves to consistency and data ac...
