Journal ArticleDOI
Nonlinear layered lattice model and generalized solitary waves in imperfectly bonded structures
TL;DR: It is shown that pure solitary waves, which exist in a single equation and can exist in the coupled system in the symmetric case, are structurally unstable and are replaced with generalized solitary waves.
Journal ArticleDOI
Fission of a longitudinal strain solitary wave in a delaminated bar.
TL;DR: The aim of the paper is to show that splitting of a waveguide leads to fission of bulk solitons in solids, and to derive the so-called doubly dispersive equation (DDE) for a long nonlinear longitudinal bulk wave propagating in an elastic bar of rectangular cross section.
Journal ArticleDOI
Longitudinal-strain soliton focusing in a narrowing nonlinearly elastic rod
TL;DR: In this article, the evolution of a longitudinal-strain solitary wave (a soliton) was studied theoretically and in experiments in a nonlinearly elastic tapered rod with decreasing cross-section.
Journal ArticleDOI
Pattern formation and nuclear divisions are uncoupled in Drosophila segmentation: comparison of spatially discrete and continuous models
TL;DR: In this paper, the relationship between pattern formation in Drosophila segment determination and nuclear structure by replacing the nuclei by a homogeneous continuum was investigated, and it was concluded that nuclear divisions are not coupled to pattern formation and serve only to populate the blastoderm with nuclei.
Journal ArticleDOI

TL;DR: The mechanisms of gap gene expression canalization in early Drosophila embryos were clarified in the case of hunchback in well defined terms of the dynamical system theory.
