A water soluble polysaccharide, HB-1, with a molecular weight of 23,930, was isolated from radix Ranunculi ternati. by hot water extraction, ethanol precipitation, deproteination，ultrafiltration and gel-filtration column chromatography. Its sugar composition was determined by GLC as Glc, Ara, and Gal in a molar ration of 16.071: 2.722: 1. And the absolute configuration of Glc was identified as ...

A product line is a set of products and features with constraints on which subsets are available. Numerous configurators have been made available by product line vendors on the internet, in which procurers can experiment with the different options, e.g. how the selection of one product or feature entails or precludes the selection of another product or feature. We explore an approach to configu...

creating and preserving large patches in land use configuration and satisfying compactness and contiguity in land use configuration are nature-prescribed and nature-inspired criteria that can be used in land use planning better that before. accompanying compactness and contiguity as the important landscape metrics in land use planning and land use configuration is close to applying proactive ap...

Deriving concrete products from a product-line infrastructure requires resolving the variability captured in the product line, based on the company market strategy or requirements from specific customers. Selecting the most appropriate set of features for a product is a complex task, especially if quality requirements have to be considered. Resource-usage-aware configuration aims at providing a...

Introduction: Long bone examination in standing position, as one of the diagnostic methods in plain radiography, is most commonly used in the field of medical diagnosis, especially leg length discrepancy. However, with regard to this examination, reproductive organs are exposed to radiation as they are placed in the adjacent area to the long bone. Due to the sensitivit...

Goodman, J.E. and R. Pollack, The complexity of point configurations, Discrete Applied Mathematics 31 (1991) 167-180. There are several natural ways to extend the notion of the order of points on a line to higher dimensions. This article focuses on three of them-combinatorial type, order type, and isotopy class-and surveys work done in recent years on the efficient encoding of order types and o...

Many existing network protocols need to be adaptively configured for the prevailing network conditions. This paper presents a scalable and flexible network protocol configuration tool, the on-line simulation scheme. The optimal configuration of network protocols can be formulated as a black-box optimization problem where the network is considered as a black-box and its performance can be evalua...

Knowledge extraction is increasingly attracting the attention of researchers from different disciplines, as a means to automate complex tasks that rely on bulk textual resources. However, the configuration of many devices in the networking field continues to be a labor intensive task, based on the human interpretation and manual entry of commands through a text-based user interface. Typically, ...
