We study the pairing within the Peierls-HubbardModel for electronand hole-doped analogs of C60 accessible to exact diagonalization techniques (cube, truncated tetrahedron, etc.). We discuss how inclusion of electronphonon interactions can substantially modify the conclusions about pairing obtained when this coupling is neglected. We also discuss potential pitfalls in the extrapolation from thes...
This paper proposes a simple and efficient technique to generate uniformly random points in a tetrahedron. The technique generates random points in a cube, and folds the cube into the barycentric space of the tetrahedron in a way that preserves uniformity.
Due to its low cytotoxicity, high resistance to enzymatic degradation, and cellular permeability, a DNA tetrahedron-based molecular beacon (DTMB) is designed for tumor-related TK1 mRNA detection in living cells, where the target sequence can induce the tetrahedron from contraction to extension, resulting in fluorescence restoration.
We present an algorithm for ray–tetrahedron intersection. The algorithm uses Plücker coordinates to represent the ray and the edges of the tetrahedron and employs a robust and efficient test to determine the intersection. The algorithm is highly optimized and provides a significant performance increase over related algorithms.
A discrete Fourier analysis on the dodecahedron is studied, from which results on a tetrahedron is deduced by invariance. The results include Fourier analysis in trigonometric functions, interpolation and cubature formulas on these domains. In particular, a trigonometric Lagrange interpolation on the tetrahedron is shown to satisfy an explicit compact formula and the Lebesgue constant of the in...
