The author considers triples \((S, G, J)\) in \(S^3\), where \(S\) is a 2-manifold with boundary, \(G\) is a circle together with \(n\) oriented chords, and \(J\) is an oriented arc on the circle. Moreover \(S\) is a regular neighborhood of \(G\) in \(S\).

The nonbonded steric interactions of substituents at the crowded C4 and C5 positions of phenanthrene cause the aromatic system to twist out of planarity. Similarly, the presence of substituents at the C1 and C12 positions of benzo[c]phenanthrene and at the C1 and C14 positions of dibenzo[c,g]phenanthrene are responsible for the helical twists of the ...

DEVELOPMENT Cells initiate and are subject to a great many morphogenetic movements—such as migration, stretching, and invagination—during early embryogenesis. The mechanics at play when cells shuffle around may serve not only to get them to the right place at the right time but also to regulate gene expression. Desprat et al.
