What's the difference between creeping and reptation?
Creeping
Definition:
(p. pr. & vb. n.) of Creep
(a.) Crawling, or moving close to the ground.
(a.) Growing along, and clinging to, the ground, or to a wall, etc., by means of rootlets or tendrils.

(15) Since prosthetic meniscal replacement may be performed in the setting of normal articular cartilage, a prosthesis will be required to match the exact joint configuration, induce the same lubricity, produce the same coefficient of friction, and absorb and dampen the same joint forces (without incurring significant creep or abrasion) as does the normal meniscus.

(18) Diacridines linked by a rigid, polar but neutral dicarbamoylpyrazole chain retain slow exchange kinetics, have a greatly reduced potential "creep rate", and possess good in vitro potency and significant in vivo antileukemic activity.
(19) Acceleration of the creep test by increasing the test temperature permits an estimation whether the creep properties of a material are within the required limits within a week.
(20) The lessons of creeping loss of control made us decide to go private again if we possibly could.
Reptation
Definition:
(n.) The act of creeping.
Example Sentences:
(1) Using fundamental concepts of hydrodynamics in porous media, we have rederived the Lumpkin-DèJardin-Zimm (LDZ) model for the gel electrophoresis of reptating, infinitely long, worm-like chains, such as DNA.
(2) Reptation theory predicts that channel gating will occur on the millisecond time scale and this is consistent with experimental results from single-channel recording.
(3) In polyacrylamide gel electrophoresis, the retardation of DNA molecules containing regions of intrinsic curvature can be explained by a novel reptation model that includes the elastic free energy of the DNA chain.
(4) These observations cannot be explained either by sieving or by reptation mechanisms; transport was apparently controlled by spatial variations of chain configurational entropy.
(5) The biased reptation model provides a good framework for interpreting the results of continuous field DNA electrophoresis experiments performed in agarose gels.
(6) The dependence of effective radius on PE and the proximity of 2.PcE to the length of the rod are explained by (a) random orientation of rods at PE values in the region of the plateau, and (b) increasingly preferential end-first orientation (reptation) of the rod as PE decreases below PcE.
(7) The other process, slow, is characterized by a reptation time and a mean orientation factor in good agreement with the biased reptation model without overstretching.
(8) The electrophoretic differences were interpreted within the reptation theory to be mainly due to the molecular stiffness differences.
(9) It is shown that both the Ogston sieving and reptation migration mechanisms are operative.
