We study Hamiltonian unfolding—cutting a convex polyhedron along a Hamiltonian path of edges to unfold it without overlap—of two classes of polyhedra. Such unfoldings could be implemented by a single zipper, so they are also known as zipper edge unfoldings. First we consider domes, which are simple convex polyhedra. We find a family of domes whose graphs are Hamiltonian, yet any Hamiltonian unf...

Various mechanisms have been proposed for the dynamic cause and kinematic development of gneiss domes. They include (1) diapiric fl ow induced by density inversion, (2) buckling under horizontal constriction (i.e., extension perpendicular to compression), (3) coeval orthogonal contraction or superposition of multiple phases of folding in different orientations, (4) instability induced by vertic...

Identifying seafloor methane seepage efficiently has important implications for assessing environmental impact, reducing the uncertainty of top seal integrity, understanding petroleum system, and mitigating drilling hazards due to shallow gas influx. Pore water geochemistry analyses suggest that study area an extremely high flux active anaerobic oxidation processes. However, geochemical data ca...

Shape annealing, a computational design method applied to structural design, has been extended to the design of traditional and innovative three-dimensional domes that incorporate the design goals of efficiency, economy, utility, and elegance. In contrast to deterministic structural optimization methods, shape annealing, a stochastic method, uses lateral exploration to generate multiple designs...

in order to investigate the structural behaviour of persian brick masonry domes, three types of semi-circular, (drop, ordinary and raised) four-centred and (drop, ordinary and raised) pointed domes have been studied. the three-dimensional non-linear finite element method using the ansys code has been used for analysis. domes with different thicknesses and spans have been subjected to monotonic ...

To determine the role of NT3 in the postnatal maturation of Merkel cell (MC) sensory neurite complexes (touch domes), we examined the development of their neural and end-organ components in wild-type and transgenic mice that overexpress NT3 (NT3-OE). Touch domes are sensory complexes of the skin that contain specialized MCs innervated by slowly adapting type 1 (SA1) neurons. Touch domes are dep...

[1] The two large low shear velocity provinces (LLSVPs) at the base of the lower mantle are prominent features in all shear wave tomography models. Various lines of evidence suggest that the LLSVPs are thermochemical and are stable on the order of hundreds of million years. Hot spots and large igneous province eruption sites tend to cluster around the edges of LLSVPs. With 3‐D global spherical ...

The author describes the use of implants with exteriorized injection domes for patients undergoing breast augmentation. Domes were exteriorized for 1 to 5 days to allow the implant volume to be altered in the early postoperative period. Thirty-three patients were treated without any infections.

Mare domes, small shield volcanoes typically <∼30 km diameter, are part of the spectrum lunar volcanic features that characterize extrusive basalt deposits. We used new spacecraft data to document these in Tranquillitatis, among oldest maria and site commonly interpreted as an ancient degraded non-mascon impact basin. found 283 known suspected mare with majority (n = 229) concentrated on a broa...
