Using alternating Heegaard diagrams, we construct some 3-manifolds which admit diffeomorphisms such that the non-wandering sets of the diffeomorphisms are composed of Smale–Williams solenoidExpand

In this paper, we show that rational homology 3-spheres are ubiquitous from the viewpoint of Heegaard splitting. Let M = H+ ∪F H− be a genus g Heegaard splitting of a closed 3-manifold and c be aExpand

Orientable hyperbolic 4-manifolds over the 120-cell.
Since there is no hyperbolic Dehn filling theorem in higher dimensions, it is difficult to construct concrete hyperbolic manifolds of small volume in dimension at least four. We build up a census ofExpand

Geometrically bounding 3-manifold, volume and Betti number.
It is well known that an arbitrary closed orientable $3$-manifold can be realized as the unique boundary of a compact orientable $4$-manifold, that is, any closed orientable $3$-manifold is cobordantExpand

Reaction Mechanisms in the Formation of Lead Zirconate Titanate Solid Solutions under Hydrothermal Conditions
Reaction mechanisms in the formation of PZT solid solution were studied under hydrothermal conditions (Pb/(Zr+Ti) = 1.0 to 1.9, Zr/Ti = 0/10 to 10/0, 1M to 5M KOH, 100° to 220°C, 2 h). A yellowExpand

Wear analysis of swash plate/slipper pair of axis piston hydraulic pump
Abstract The paper presents a method on the basis of Elasto Hydrodynamic Lubrication (EHL) model to analyze the wear behavior of swash plate/slipper pair. Based on the analysis of film thickness, theExpand

Large dynamic range high resolution digital delay generator based on FPGA
A novel digital delay generator (DDG) based on FPGA was designed with 4.4ms range and 65ps resolution. The time-to-digital conversion (TDC) utilizing dual tapped delay lines was implemented in theExpand

[Alkaloids from Stephania succifera H. S. Lo et Y-Tsoong].
Eight alkaloids were isolated from Stephania succifera H. S. Lo et Y-Ts0ong. Alkaioids Ⅰ, Ⅱ, Ⅲ, Ⅳ and Ⅷ were identified as dehydrocrebanine, (1)-tetrahydropalmatine, crebanine, schefferine andExpand
