Wang N. et al. reported the discovery of a new type of two-dimensional quasicrystal with eightfold symmetry in rapidly solidified Cr<sub>5</sub>Ni<sub>3</sub>Si
A graph G is called claw-flee if G contains no induced subgraph isomorphic to K<sub>1,3</sub>,Line graphs, an important class of graphs, are claw-free graphs. E
Since the discovery of high temperature oxide superconductors in 1986, it is possible to adapt superconducting materials for technological applications at liqui
Most of the mitochondrial proteins are encoded by nuclear genes and synthesized on cytoplasmic ribosomes as larger precursors. These mitochondrial precursors ar
In 1975, B. B. Mandelbrot presented the Fractal Geometry through careful observation and comprehensive analysis of many irregular bodies with complicated shapes
in situ hybridization or hybridocytochemistry is a powerful tool for detection and localization of gene expression. It is also the most commonly used procedure
In 1967, K. Koh showed that (Ⅰ)if a ring R contains n (n】1) left (right)zero divi-sors, then |R|≤n~2; (Ⅱ)if a ring R contains n (n】1)left (right)zero divis
1. Let M ■ C~n be a bounded symmetrical domain containing the origin, and M be the canonical Harish-Chandra realization of G/K, where G is the group of holomor
