Interpenetrating Nets: Ordered, Periodic Entanglement

Angewandte Chemie International Edition, 1998
Independent one-, two-, and even three-dimensional nets interpenetrate each other in many solid-state structures of polymeric, hydrogen-bonded nets and coordination polymers. For example, the interpenetration of the adamantane units of two diamondlike nets is shown on the right.

Period Doubling with Higher-Order Degeneracies

SIAM Journal on Mathematical Analysis, 1991
The authors consider a family of local diffeomorphisms \(G(x,\mu)\), \(G(x_ 0,\mu_ 0)=x_ 0\), where i) \(G: U\to\mathbb{R}^ n\), \(U\) is a neighbourhood of \((x_ 0,\mu_ 0)\) in \(\mathbb{R}^ n\times\mathbb{R}^ k\); ii) \(D_ x(x_ 0,\mu_ 0)\) has a single eigenvalue of \(-1\) and no other eigenvalues on the unit circle; iii) on its one-dimensional ...

Almost-Periodic Higher Order Statistic Estimation

IEEE Transactions on Information Theory, 2011
In this paper, stochastic processes with higher order statistical functions decomposable into an almost-periodic function plus a residual term not containing finite-strength additive sinewave components are considered. These processes arise in mobile communications when almost-cyclostationary (ACS) processes pass through time-varying channels.

Periodic Phases in Second-Order Materials

Archive for Rational Mechanics and Analysis, 1998
The title of this paper is misleading because the notion of ``second-order'' materials is not uniquely accepted. Here the authors are in fact dealing with a material whose energy density depends not only on density and its first spatial gradients (like in some approaches to capillarity), but also on the second gradient of density. These would be called

Third-order systems: Periodicity conditions

International Journal of Non-Linear Mechanics, 2009
Abstract Recently a third-order existence theorem has been proven to establish the sufficient conditions of periodicity for the most general third-order ordinary differential equation x ‴ + f ( t , x , x ′ , x ″ ) = 0 In this paper we prove a new theorem, and establish a new sufficient condition for ...
