Characterization of in vivo human skin in response to mechanical indentation using optical coherence tomography
… condition of an individual. Both the intrinsic stiffness of the solid constituents and the time-evolved redistribution of fluid within skin tissue can influence the biomechanical response to external forces. Therefore, it is important not only to evaluate the responding skin dynamics …

Control of cell fate decisions of embryonic stem cells by mechanical forces
… We found that soft substrates that match the intrinsic stiffness of the cell can maintain populations of mESC culture homogeneously in an undifferentiated state. The underlying biophysical mechanism is to match matrix substrate stiffness to that of the mESCs which in turn generates low …

Linear System Analyses of the Role of Reflex Gain and Delay in a Dynamic Human Spine Model
… models to aid in understanding of how intrinsic stiffness stabilizes the spine. This work expands these previous studies by modeling the neuromuscular dynamic control of the spine. The presence of delay in the reflexive system limits the availability of traditional stability analyses. …

Role of Intrinsic and Reflexive Dynamics in the Control of Spinal Stability
… and control of active paraspinal muscle stiffness (i.e., trunk stiffness). The two major components of active muscle stiffness include the immediate stiffness contribution provided by the intrinsic stiffness of actively contracted muscles, and the delayed stiffness contribution provided …

Alutiiq Engineering: The Mechanics and Design of Skeletal Technologies in Alaska's Kodiak Archipelago
… the mechanical properties of Young's modulus (intrinsic stiffness), intrinsic strength, and fracture resistance of the compact tissue of reindeer antler, cervid long bones, and the limb bones of the California sea lion. Cervid compact limb tissue is stiff, strong, and brittle, while reindeer …

Post fatigue changes in the stability of cervical spine
… of the myoelectric silence period by 17.2%. The intrinsic stiffness of cervical spine was reduced from 975.75 +/- 85.87 Kg/sec2 pre-fatigue to 826.31 +/- 90.76 Kg/sec2 post-fatigue. The corresponding change in the effective stiffness was from 1404.64 +/- 122.31 Kg/sec 2 to 1086.53 +/- 123.73 …
