Increasing tensile properties and collagen content is a recognized need in articular cartilage tissue engineering. This study tested the hypothesis that multiple applications of chondroitinase ABC (C-ABC), a glycosaminoglycan (GAG) degrading enzyme, could increase construct tensile properties in a scaffold-less approach for articular cartilage tissue engineering. Developing constructs were trea...

Artificial Bee Colony (ABC) algorithm simulates the foraging behavior of honey bee colonies. ABC is an optimization technique, which is used in finding the best solution from all feasible solutions. However, there is still an insufficiency in ABC regarding improvement in exploitation and convergence speed. In order to improve the performance of ABC we embedded PSO into ABC. As PSO has memory, k...

In this paper, we show how the concepts of objects, components, features and agents are used today in the Agent Building Center (ABC) environment in order to marry the modelling of functionally complex communication systems at the application level with an objectoriented, component based implementation. In particular the ABC enables domain experts, designers, and test engineers to graphically d...

As the field of phylogeography has continued to move in the model-based direction, researchers continue struggling to construct useful models for inference. These models must be both simple enough to be tractable yet contain enough of the complexity of the natural world to make meaningful inference. Beyond constructing such models for inference, researchers explore model space and test competin...

RNA interference (RNAi) is a conserved gene-silencing phenomenon that can be triggered by delivery of double-stranded RNA (dsRNA) to cells and is a widely exploited technology in analyses of gene function. Although a number of proteins that facilitate RNAi have been identified, current descriptions of RNAi and interrelated mechanisms are far from complete. Here, we report that the Caenorhabditi...

INTRODUCTION The Mini-Mental State Examination (MMSE) is a common cognitive screening test, but its utility in identifying impairments in survivors of acute respiratory failure is unclear. The purpose of this study was to evaluate MMSE performance versus a concurrently administered detailed neuropsychological test battery in survivors of acute respiratory failure. METHODS This cross-sectional...

In this paper we test the ABC event-aware metadata model, developed within the Harmony project, by applying it to a complex multimedia oral history archive. Based on a metadata schema, generated using the ABC model, we developed indexing tools, a database and a search and browse Web interface, for an oral history collection consisting of audio tapes and posters generated from a series of interv...
