Inversion and eversion are movements that tilt the sole of the foot away from (eversion) or towards (inversion) the midline of the body. [35] Eversion is the movement of the sole of the foot away from the median plane. [36] Inversion is the movement of the sole towards the median plane. For example, inversion describes the motion when an ankle ...
It follows from the definition that the inversion of any point inside the reference circle must lie outside it, and vice versa, with the center and the point at infinity changing positions, whilst any point on the circle is unaffected (is invariant under inversion). In summary, for a point inside the circle, the nearer the point to the center ...
An inversion is a chromosome rearrangement in which a segment of a chromosome becomes inverted within its original position. An inversion occurs when a chromosome undergoes a two breaks within the chromosomal arm, and the segment between the two breaks inserts itself in the opposite direction in the same chromosome arm.
In structural geology, inversion or basin inversion relates to the relative uplift of a sedimentary basin or similar structure [example needed] as a result of crustal shortening. This normally excludes uplift developed in the footwalls of later extensional faults , or uplift caused by mantle plumes .
The idea of a somatic twist was inspired by the dorsoventral inversion hypothesis; [27] [28] and was proposed by Marcel Kinsbourne. [24] According to the dorsoventral inversion hypothesis, an ancestral deuterostome turned on its back. As a result, vertebrates have a dorsal nervous system, whereas protostomes have a ventral one.

Its vertex–center–vertex angle—the angle between lines from the tetrahedron center to any two vertices—is = (), denoted the tetrahedral angle. [9] It is the angle between Plateau borders at a vertex. Its value in radians is the length of the circular arc on the unit sphere resulting from centrally projecting one edge of the ...
As noted above, the inverse with respect to a circle of a curve of degree n has degree at most 2n.The degree is exactly 2n unless the original curve passes through the point of inversion or it is circular, meaning that it contains the circular points, (1, ±i, 0), when considered as a curve in the complex projective plane.
Instead of just one explanation for the face inversion effect, it is more likely that aspects of different theories apply. For example, faces could be processed with configural information but the role of experience may be important for quickly recognising a particular type of face (i.e. human or dog) by building schemes of this facial type.
