One-Step Enzymatic Synthesis of 1-Tuliposide A Using Tuliposide-Converting Enzyme

Applied Biochemistry and Biotechnology - 6-Tuliposides A (6-PosA) and B (6-PosB) are major secondary metabolites in tulip (Tulipa gesneriana), having an acyl group at the C-6 position of d-glucose....     

Subgraphs and the Laplacian spectrum of a graph

Let G be a graph and H a subgraph of G. In this paper, a set of pairwise independent subgraphs that are all isomorphic copies of H is called an H-matching. Denoting by ν(H,G) the cardinality of a maximum H-matching in G, we investigate some relations between ν(H,G) and the Laplacian spectrum of G.     

Generation of 10- microJ coherent extreme-ultraviolet light by use of high-order harmonics

We demonstrate the generation of 10-microJ coherent extreme-ultraviolet (XUV) light at wavelengths from 73.6 to 42.6 nm, using high-order harmonics. The peak power of this coherent XUV light is estimated to be 0.13 GW at 62.3 nm, and the peak brightness achieved was 3x10(28) photons/(mm(2)mrad(2)s) . To our knowledge, this XUV energy is the highest value achieved with high-order harmonics.

Weak type estimates for Calderón‐Zygmund operators on Herz spaces at critical indexes

We define weak Herz spaces (?ⁿ) which are the weak version of the ordinary Herz spaces (?ⁿ). We consider the boundedness of Calderón‐Zygmund operators from to at critical indexes α = ?n/q, n(1? 1/q) and q = 1. We also consider weighted estimates. (© 2003 WILEY‐VCH Verlag GmbH & Co.

Ultrasonic cavitation in microspace

Ultrasound was irradiated to a micro-1D and -2D space having a characteristic length of 200 microm, and the presence of cavitation was confirmed from video images, and the generation of OH radicals, which was quantitatively evaluated with fluorometry.
