To identify genetic diversity, genetic structure and the relationship among accessions, and further establish a core collection for the long-term breeding of cypress (Cupressus funebris Endl.), the genealogy of breeding parents was reconstructed using simple sequence repeat (SSR) molecular markers. Seventeen SSR markers were used to detect molecular polymorphisms among 290 cypress accessions fr...

The cypress family (Cupressaceae) possesses highly rearranged plastomes that lack a pair of large inverted repeats typically found in land plants. A few cypress species have been reported to contain isomeric plastomes, but whether the existence of isomeric plastomes is ubiquitous in the family remains to be investigated with a broader taxon sampling. In this study, we sequenced the complete pla...

In an attempt to bootstrap classical homotopy theoretic tools into the world of abstract spacetime, we identify a criterion under which two maps of compact pospaces which are homotopic in the classical sense are also homotopic through monotone maps. As a corollary, we show that a hypercontinuous lattice equipped with its Lawson topology is contractible through monotone maps if its underlying sp...

Using the notion of integrating factors, Lawson developed a class of numerical methods for solving stiff systems of ordinary differential equations. However, the performance of these “Generalized Runge–Kutta processes” was demonstrably poorer when compared to the ETD schemes of Certaine and Nørsett, recently rediscovered by Cox and Matthews. The deficit is particularly pronounced when the schem...

This project concerns an important conjecture which appears to have been solved recently: It concerns minimal surfaces, in particular minimal submanifolds of spheres. It combines PDE and geometry, though the PDE required is not very much. It does involve some basic spectral theory for the Laplacian on a Riemannian manifold. There are many examples known of submanifolds in spheres which are mini...

The novel skeleton compounds, chamaecypanone C (3) and obtunorlignan A (4) were isolated from the heartwood of Chamaecyparis obtusa var. formosana. The structure of 3 was elucidated as a dimeric of monoterpene and norlignan with tricyclo[5.2.2.0]undecane and the structure of 4 was elucidated as a norlignan skeleton by spectroscopic methods. Compound 3 exhibits potent cytotoxic activity against ...
