The phrase "a less stiff" is correct and usable in written English.
It can be used when comparing the stiffness of two or more items, indicating that one is not as stiff as the other.
Example: "I prefer a less stiff fabric for my summer clothes to ensure comfort in the heat."
Alternatives: "a more flexible" or "a softer".
Should primary fixation be provided, friction has a secondary importance with respect to bone ingrowth while the influence of stiffness was counter intuitive: a less stiff backing material inhibits bone ingrowth by higher interface micromotions and stimulation of fibrous tissue formation within the backing.
The innermost region contains chitin, a less stiff material often found in the exoskeletons of crustaceans stacked in helices with hydroxyapatite filling in between the stacks.
Uniaxial tensile and inflation tests confirmed the scaffold maintains its non-linear response, however a less stiff, more distensible low-load response and stiffer high-load response was found compared to non-decellularised sections.
Three track types are compared using the vibro-acoustic model: an existing slab track with embedded UIC54 rails, a newly designed, acoustically optimized slab track with a less stiff rail embedded in a stiffer elastomere, and, as a reference, a ballasted track.
Mechanically, a less stiff, more compliant, system will be exposed to greater frontal plane motion, which may contribute toward both joint instability and cartilage damage [ 34, 35].
Using a von Frey filament series (0.6, 1.4, 2, 4, 6, 8, 15, and 26 g), a withdrawal tolerance sequence was constructed wherein a less stiff filament was applied following a paw withdrawal and a more stiff filament was applied following filament tolerance.
Recent designs with either all-polyethylene cementless fixation or using a less-stiff, integrated tantalum backing have promising early results.
The analysis shows that the additional energy collection by a less-stiff, larger heliostat more than offsets the spillage due to the greater deformation of the same.
Interestingly, AD-MSCs treated with GDF6 produced a less-stiff, PG-rich matrix, which may be more indicative of the native healthy NP ECM.
Micromechanical analysis shows that the GDF6-treated AD-MSCs have a less-stiff matrix composition, suggesting that the growth factor is inducing a matrix that is more akin to the native NP-like tissue.
The format for the second presidential debate is designed to be a little less stiff — a free-flowing question-and-answer session between the candidates and a studio audience.
