Spatial and depth dependent viscoelastic behavior of articular cartilage
The mechanical response of the soft tissues of the knee is nonlinear, anisotropic, and viscoelastic. Individual tissues may also express nontrivial gradients of material properties throughout their structure, adding to the modeling complexity of the anatomy. Computational models of whole knee biomechanics can be extremely useful in understanding the progression of degenerative diseases and trau...
متن کاملSpherically symmetric random walks. II. Dimensionally dependent critical behavior.
A recently developed model of random walks on a D-dimensional hyperspherical lattice, where D is not restricted to integer values, is extended to include the possibility of creating and annihilating random walkers. Steady-state distributions of random walkers are obtained for all dimensions D.0 by solving a discrete eigenvalue problem. These distributions exhibit dimensionally dependent critica...
متن کاملDepth-dependent blur adaptation
Variations in blur are present in retinal images of scenes containing objects at multiple depth planes. Here we examine whether neural representations of image blur can be recalibrated as a function of depth. Participants were exposed to textured images whose blur changed with depth in a novel manner. For one group of participants, image blur increased as the images moved closer; for the other ...
متن کاملDepth-dependent contrast gain-control
Contrast adaptation that was limited to a small region of the peripheral retina was induced as observers viewed a multiple depth-plane textured surface. The small region undergoing contrast adaptation was present only in one depth-plane to determine whether contrast gain-control is depth-dependent. After adaptation, observers performed a contrast-matching task in both the adapted and a non-adap...
متن کاملDielectric analysis of depth dependent curing behavior of dental resin composites.
OBJECTIVES The aim of this study is to investigate depth dependent changes of polymerization process and kinetics of visible light-curing (VLC) dental composites in real-time. The measured quantity - "ion viscosity" determined by dielectric analysis (DEA) - provides the depth dependent reaction rate which is correlated to the light intensity available in the corresponding depths derived from li...
