• It is anatomically distinguished from members of the genus Canis in several aspects: its skull is convex rather than concave in profile, it lacks a third lower molar and the upper molars possess only a single cusp as opposed to between two and four.
• In telecommunications and radar, a Cassegrain antenna is a parabolic antenna in which the feed antenna is mounted at or behind the surface of the concave main parabolic reflector dish and is aimed at a smaller convex secondary reflector suspended in front of the primary reflector.
• Giambattista Della Porta wrote in 1558 in his Magia Naturalis about using a concave mirror to project the image onto paper and to use this as a drawing aid.
• A glen is a valley, typically one that is long and bounded by gently sloped concave sides, unlike a ravine, which is deep and bounded by steep slopes.
• Because rescue was uncertain, the survivors engraved their names on the concave side of a large turtle shell, which is displayed in the South Australian Museum, on North Terrace in Adelaide.
• On the other hand, when adhesion dominates (when adhesion energy is more than half of cohesion energy) the wetting is high and the similar meniscus is concave (as in water in a glass).
• Shield- Parti per chevron couped and concave Argent and Gules in chief a sun between three six pointed mullets one and two all of the second, on a canton of the like a mule with mountain artillery pack Or (for the Second Field Artillery).

• A concave lens of flint glass is commonly combined with a convex lens of crown glass to produce an achromatic doublet lens because of their compensating optical properties, which reduces chromatic aberration (colour defects).
• When faced with a risky choice leading to gains agents are risk averse, preferring the certain outcome with a lower expected utility (concave value function).
• Lipperhey's original instrument consisted of either two convex lenses with an inverted image or a convex objective and a concave eyepiece lens so it would have an upright image.
• The design of these early refracting telescopes consisted of a convex objective lens and a concave eyepiece.
• In lens systems, aberrations can be minimized using combinations of convex and concave lenses, or by using aspheric lenses or aplanatic lenses.
• However, equilateral pentagons, and equilateral polygons with more than five sides, can also be concave, and if concave pentagons are allowed then two angles are no longer sufficient to determine the shape of the pentagon.

• Water-based fluids like sap, honey, and milk also have a concave meniscus in glass or other wettable containers.
• The inferior surface articulates with the proximal end of the second metacarpal bone; it is convex from side to side, concave from before backward and subdivided by an elevated ridge into two unequal facets.
• The slope measured from the apex is generally concave, with the steepest slope near the apex (the proximal fan or fanhead) and becoming less steep further out (the medial fan or midfan) and shallowing at the edges of the fan (the distal fan or outer fan).
