Reasoning about Spatial Relationships

We explore a new architecture for representing spatial information in neural networks. The method binds object information to position via element-wise multiplication of complex-valued vectors. This approach extends Holographic Reduced Representations by providing additional tools for processing and manipulating spatial information. In many cases these computations can be performed very efficie...

Developing Successful B2B Relationships

described how the Internet enables a new supply chain paradigm, a push-pull paradigm that replaces the traditional push model. In the past, most companies operated by forecasting long-term demand, mass-producing inventories of product to fulfill the anticipated demand and then "pushing" the inventories on to the customer. The disadvantage of the push model is that production decisions are based...

Improving Quantitative Structure-Activity Relationships through Multiobjective Optimization

A multiobjective optimization algorithm was proposed for the automated integration of structure- and ligand-based molecular design. Driven by a genetic algorithm, the herein proposed approach enabled the detection of a number of trade-off QSAR models accounting simultaneously for two independent objectives. The first was biased toward best regressions among docking scores and biological affinit...

Structure-activity relationships of antioxidant activity in vitro about flavonoids isolated from Pyrethrum tatsienense

AIM Antioxidant activity is one of the important indexes for estimating medicinal value for the traditional Chinese medicine. The aim of this study is to investigate the antioxidant activity of 11 flavonoids mainly revealing luteolin as mother nucleus isolated from Pyrethrum tatsienense. MATERIALS AND METHODS The antioxidant activity of 11 flavonoids was measured in vitro using the classical ...
