The increased expression of elastase reflects degradation of elastin fibers and hence increased stiffness of the vessel wall.
Protein folding decreases the effective contour length of titin, leading to increased stiffness.
After cycling, all tapes loaded to failure showed increased stiffness (P < 0.001), indicating significant energy absorption during cycling.
In particular, the awkwardly framed pit saw was largely replaced by a long, two-handled blade of increased stiffness.
Compared with structures that had no pockets, pockets filled with air, and pockets filled with water, the gallium-infused structure showed markedly increased stiffness and toughness.
Cancer cells behaved differently, exhibiting increased stiffness as well as stiffness variability when subjected to nocodazole.
As expected, increased chemical crosslinking of polyacrylamide increased stiffness (E⩽40 kPa) and decreased creep compliance.
This led to increased stiffness and higher values of maximum loads.
The rheological analysis of cryobeads showed its stability and increased stiffness after uranium adsorption.
The result is a "fully stressed" structure with minimized compliance and increased stiffness.
Mechanically, IGF-I treated tendons showed a trend toward increased stiffness compared to saline treated controls.
