The overall investment in attack increases concavely in the firm's unit defense cost, decreases convexly in the hackers' unit cost of attack, and increases linearly in the firm's asset.
Specifically, while the firm's cyber security investment and profit decrease convexly, the hackers' information sharing increases convexly, and the hackers' profits increase as well.
As the hackers' unit cost of attack increases, the firm's profit increases, while the hackers' information sharing and profit decrease convexly.
We prove that S' contains k' mutually disjoint subsets if and only if G has a convexly independent set of size k,
Conversely, by hypothesis G has a convexly independent set S of size k.
Aedeagal shaft with short curved processes at apex; subgenital plate convexly
Small, cylindrical shell of 5 to 6 whorls; protoconch smooth, depressed; ultimate whorl three times length of spire, tapering convexly
to base; whorls gradate, sharply shouldered with flat to slightly inclined ramps; surface smooth; apical angle of 80 degrees.
The PPHMDSO film on the porous PSf support is under compressive internal stresses, causing the membrane to convexly
bend with respect to the film.
deforms the absorbent laminate toward the skin-contactable side.
The liquid-absorbent core is formed in a transverse middle portion with a protuberant region convexly
curved toward a body side of the napkin.
The article features an absorbent laminate and deformation-inducing means provided adjacent to the skin's non-contactable side, so as to convexly deform the laminate toward the skin-contactable side.
The deformation inducing means, including panel and elastically stretchable members, has transverse ends secured in a vicinity of the deformation assisting means near the panel member, so as to convexly deform the panel member about the longitudinal axis toward the skin-contactable side as elastically stretchable member elastically contracts.
