A new daphnane diterpene was isolated from the root barks of Daphne tangutica Maxim.Its structure was elucidated as 1, 2α-dihydro-20-palimoyldaphnetoxin by the
The crystal structure of 2-methylthio-3-cyano-7-(4-methoxyphenyl)-pyrazolo[1,5- a]-pyrimidine (C15H12N4OS, Mr = 296.35) has been determined by single-crystal X-
With the help of Bose operator identities and entangled state representation and based on our previous work [Phys. Lett. A 325 (2004) 188] we derive some new ge
We present a scheme to entangle fields in multiple cavities. Our scheme is based on the resonant interaction of a Ξ-type three-level atom with the cavity field
How to combine color and multiscale information is a fundamental question for computer vision, and quite a few color diffusion techniques have been presented. M
The optimized molecular structures and vibrational frequencies of 4-mercaptopyridine(4MPY) monomer and its dihydrate were studied by means of the density functi
