in southwest of China. Its stems were used in folk medicine for the treatment of rheumatism, traumatic injury, ulcer with pyogenic infections, stomachache and neurasthenia. Previous phytochemical investigation revealed that this plant mainly contained lignans and triterpenoids. As a part of our search for bioactive materials, the petroleum ether extract of the stems of S. propinqua showed cytot...

Particle Methods for Electromagnetic Wave Propagation Problems Report Title 1. A rigorous proof of the relation between the solutions of wave and telegraph equations in 3D via arandom time induced by a Poisson process has been provided using techniques of stochastic calculus. Application of this relation to wave propagation in dispersive media (Lorentz and Drude media) is discussed. 2. Sparse g...

The absolute configuration of the octa-hedral fac-CoN(3)O(3) title complex, [Co(C(5)H(8)NO(2))(3)]·3H(2)O, has been determined by single-crystal X-ray analysis. A three-dimensional network of hydrogen bonds is observed between the proline carboxyl-ate groups and the three uncoordinated water mol-ecules.

In a typical query learning setting we have a set S of N objects and a set Q of M distinct subsets of S that is known as queries. The purpose of query learning is to identify a single active object Si ∈ S through as few queries from Q as possible, where a query q ∈ Q returns 1 or 0 depending on whether or not Si ∈ q [1]. For example, a healthcare professional can choose from a series of tests t...
