    • n spine In botany, a stiff sharp-pointed process, containing more or less woody tissue, and originating in the degeneracy or modification of some organ. Usually it is a branch or the termination of a stem or branch, indurated, leafless, and attenuated to a point, as in the hawthorn, sloe, pear, and honey-locust; its nature is clearly manifest by the axillary position, and also by the fact that it sometimes produces imperfect leaves and buds. A spine may also consist of a modified leaf (all gradations being found between merely spiny-toothed leaves and leaves which are completely contracted into simple or multiple spines, as in the barberry), or of a persistent petiole, as in some Astragali and in Fouquieria, or of a modified stipule, as in the common locust. A spine is to be clearly distinguished from a prickle, which is merely a superficial outgrowth from the bark. See prickle, 1.
    • n spine The backbone; the rachis, spina, or spinal column of a vertebrate. The name is due to the series of spinous processes of the several vertebræ which it presents, forming a ridge along the middle of the back. See spinal column (under spinal), and vertebra, vertebral.
    • n spine A name of some part in various animals. In anatomy, a sharp process, point, or crest of bone; a spinous process, generally stouter than a styloid process: as, the spine of the ilium, of the ischium, of the scapula, of the pubis. See cuts under innominatum and shoulder-blade.
    • n spine In much., any longitudinal ridge; a fin.
    • n spine In lace-making, a raised projection from the cordonnet: one of the varieties of pinwork; especially, one of many small points that project outward from the edge of the lace, forming a sort of fringe.

In science:

In dimension 4 we show the same data determines decompositions up to 2-deformation of their spines.
Dual 2-complexes in 4-manifolds
We define a “tamely embedded” 2-complex in N to be a spine of a 2handlebody in N , and the handlebody is a “regular neighborhood” of the complex.
Dual 2-complexes in 4-manifolds
Corollary (Realization of CW spines). A finite CW 2-complex K → N 2-deforms to the spine of half a Heegard decomposition if and only if K is connected and π1K → π1N is onto.
Dual 2-complexes in 4-manifolds
This requires a hypothesis that encodes the algebraic duality of the spines in N .
Dual 2-complexes in 4-manifolds
The next corollary shows this characterizes spines of Heegard decompositions.
Dual 2-complexes in 4-manifolds
Use the first corollary to realize K as the spine of M in a decomposition M ∪ W .
Dual 2-complexes in 4-manifolds
Given a 2-complex K we note there is a particularly simple choice for dual spine in S 4 .
Dual 2-complexes in 4-manifolds
This gives a 2-deformation between the spines of M and M ′ .
Dual 2-complexes in 4-manifolds
Let Tp be the first segment on the secondary spine, which contains an essential occurrence of zj .
Retractions of Types with Many Atoms
First of all, note that the variable y , of which Tp is the meaning must be bound on the primary spine and not on the secondary one.
Retractions of Types with Many Atoms
We have already observed that it is a leading variable of some Si on the primary spine.
Retractions of Types with Many Atoms
If this Si is the meaning of some y ′ , then the target of the type of y ′ is a, and y ′ must be bound on the primary spine too.
Retractions of Types with Many Atoms
In our simple model we in fact consider two distinct relativistic electron populations, which differ because of the spatial location (knots – jet edges), nature of the acceleration (regular – stochastic) and kinematic effects involved (fast central spine – shear boundary layer).
