Caterpillar compaction

Caterpillar compaction

Caterpillar compaction NA compaction, say Ryan Case, YunPei Chang, Nicholas Cozzarelli, Carlos Bustamante, and colleagues (University of California, Berkeley, CA), may work via a cooperative caterpillar-like mechanism. The caterpillar is formed by multiple copies of condensin protein—in this case MukBEF—with each V-shaped condensin contributing two legs. Compaction occurs when the caterpillar’s...

Compaction Variables and Compaction Specification

Compaction is a mechanical process in which an earthen material is made more dense. The densification occurs as a direct result of the mechanical loading, and is essentially complete at the end of the loading. Volume changes are incurred as a result of a reduction in the quantity of air voids— water content remaining constant. Since it is impractical to squeeze out all the air, the as-compacted...

Caterpillar Tolerance Representations

Various families of tolerance graphs of subtrees for specific families of host trees and tolerance functions have been successfully characterized. For example, chordal graphs are intersection (tolerance 1) graphs of subtrees of general trees, see [2], [5], and [8]. Intersection graphs of subtrees of a path are those that are chordal and do not contain an asteroidal triple, see [7]. We denote by...

SSA-Caterpillar in Group Anonymity

Nowadays, it is a common practice to protect various types of statistical data before publishing them for different researches. For instance, when conducting extensive demographic surveys such as national census, the collected data should be at least depersonalized to guarantee proper level of privacy preservation. In practice, even more complicated methods of data protection need to be used. A...
