Although distributed key-value store is becoming increasingly popular in compensating the conventional distributed file systems, it is often criticized due to its costly full-size replication for high availability that causes high I/O overhead. This paper presents two techniques to mitigate such I/O overhead and improve key-value store performance: GPU encoding and locality-aware encoding. Inst...

In this paper we introduce a novel architecture for data processing, based on a functional fusion between a data and a computation layer. We show how such an architecture can be leveraged to offer significant speedups for data processing jobs such as data analysis and mining over large data sets. One novel contribution of our solution is its data-driven approach. The computation infrastructure ...

A series of team-building activities were conducted on a medical-surgical unit and their impact on staff's communication and job satisfaction was examined. Forty-four unit personnel participated in the interventions. Staff communication and job satisfaction were measured before and after the intervention. The findings linked team-building activities with improved staff communication and job sat...

BACKGROUND An experiment on the relationship between aeromedical color vision screening test performance and performance on color-dependent tasks of Air Traffic Control Specialists (ATCS) was replicated to expand the database supporting the job-related validity of 13 FAA-accepted screening tests. METHODS The original experiment (10) (n = 108), and the replication (n = 136) involved a total of...

Vendor strategies to standardize grid computing as the IT backbone for service-oriented architectures have created business opportunities to offer grid as a utility service for compute and data– intensive applications. With this shift in focus, there is an emerging need to incorporate agreements that represent the QoS expectations (e.g. response time) of customer applications and the prices the...

A complication in the analysis of the role of ICP34.5 gene in the herpes simplex virus type-1 (HSV-1) lifecycle is the presence of overlapping antisense gene, open reading frame P (ORF P), which is also deleted in HSV-1 ICP34.5 negative mutants. A HSV-1 wild type strain (17+) ICP34.5/ORF P deletion mutant (1716) is totally avirulent in animal models and impaired in a number of in vitro function...

Background and Aims: Oncolytic reoviruses can infect and kill malignant cells while sparing their normal counterparts. Reoviral infection can induce or activate autophagy, even though metformin can induce autophagy. Identifying and regulating the cellular pathways important for reovirus replication and oncolysis can improve targeted-biological therapies for cancer. Here, the autophagic process ...

Experiments like ATLAS at LHC involve a scale of computing and data management that greatly exceeds the capability of existing systems, making it necessary to resort to Grid-based Parallel Event Processing Systems (GEPS). Traditional Grid systems concentrate the data in central data servers which have to be accessed by many nodes each time an analysis or processing job starts. These systems req...
