~ This paper addresses the problem of controlling a manipulator in compliant motion while in contact with an environment having an unknown stiffness. Compliance control is used as an implicit force control scheme and establishes a user-specified target interaction ciyna]nics between the reference position and the contact force. ‘J’wo adaptive lag-plusfccdfor ward compliance compensators are dev...

Caenorhabditis elegans locomotion is a stereotyped behavior that is ideal for genetic analysis. We integrated video microscopy, image analysis algorithms, and fluid mechanics principles to describe the C. elegans swim gait. Quantification of body shapes and external hydrodynamics and model-based estimates of biomechanics reveal that mutants affecting similar biological processes exhibit related...

Response of the cytoskeleton to mechanical stimulus, which involves coordinated assembly and disassembly of cytoskeletal polymers and their coupling to motor proteins, has been shown to be governed by a ubiquitous mechanical behavior called power-law rheology. Various experimental techniques in cell mechanics have yielded similar qualitative observations and quantitative behavior indicating tha...

Objectives Cage design and material properties play a crucial role in the long-term results, since interbody fusions using intervertebral cages have become one of the basic procedures in spinal surgery. Our aim is to design a novel Apatite-Wollastonite interbody fusion cage and evaluate its biomechanical behavior in silico in a segmental spinal model. Materials and Methods Mechanical properti...
