Concave

Property that a curve is below a straight line connecting two end points. If the curve falls above the straight line, it is called convex.

Concave

Describing a curve segment whose ends fall below an arbitrarily set straight line. Concave properties are important to charting; for example, when tracking a stock market's performance, a dip in the chart with respect to the previous day's close followed by a rally going up to but not necessarily meeting that close may be described as a concave curve.

By dissecting the lateral crus, flipping it over, and putting it back in place we can "reconstruct" a new lateral crus and reshape it to correct the concavity without the need to harvest additional grafting material.
Steepness and concavity of the area revealed 116 small and large stream linkages that were limited by incision detachment model (IDM) and channel profile analyses which were carried out by regression model in the first place (Fig.

(2) The crack initiates at the tool tip, subsequently propagates downward and forward, and then spreads gradually toward the free surface of the workpiece, resulting in the removal of a block of graphite surrounded by the crack and the formation of a concavity on the machined surface.
