The poem's formal properties are ways of managing the rate at which tape-time elapses: when Ammons's lines are long, spanning the width of the tape, he preserves the length and buys more time; when he prints a narrow strip of words, more of the tape (and so, functionally speaking, more of the time) is gobbled up.
Sometimes one needs to approximate a curve by means of splines that preserve the length of the given curve.
That geometry requires of the symmetric linear connection \ \Gamma\) that the infinitesimal parallel transport of a vector always preserves the length of the vector.
As an orthogonal transform, Eq. (9) preserves the signal energy or, equivalently, preserves the length of the vector y v [22], i.e., left| {mathbf{f}_{v}} right|^{2} = left| {mathbf{y}_{v}} right|^{2}.
These modes correspond to an infinitesimal affine transformation of the structure that preserves the length of conventional members, they hold over finite displacements and are present if and only if the directional vectors of those members lie on a projective conic.
The Nichols algebra ({mathcal {B}}(V) = oplus _{nin mathbb {N}_0} {mathcal {B}}^n (V)) of (V, c) is a graded connected algebra with a number of remarkable properties that has at least superficially a resemblance with a symmetric algebra.1 For, let (M_n,mathbb {S}_n rightarrow mathbb {B}_n) be the (set-theoretical) Matsumoto section, that preserves the length and satisfies (M_n(s_j) = sigma _j).
For negative energies −– i.e., for bound systems −– the higher symmetry group is SO(4), which preserves the length of four-dimensional vectors : \left| \mathbf{e} \right|^{2} = e_{1}^{2} + e_{2}^{2} + e_{3}^{2} + e_{4}^{2}.
Increased apparent RNA binding in the UV crosslinking assay for ΔNΔRS and ΔRS: Δ5-10 proteins may be a consequence of removal of a portion of the inhibitory N-terminus, whereas the R8E mutation may not increase RNA binding to the same extent in this assay because it preserves the length of the inhibitory N-terminal extension to RRM1.
The transformation between Q and X does not preserve the length minimizing property.
In fact, selection could preserve the length of these microsatellites, even those with high rates of expansion and contraction, if length changes were highly deleterious.
