2D Affine and Projective Shape Analysis
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2014Current techniques for shape analysis tend to seek invariance to similarity transformations (rotation, translation, and scale), but certain imaging situations require invariance to larger groups, such as affine or projective groups. Here we present a general Riemannian framework for shape analysis of planar objects where metrics and related quantities ...

ECoG Analysis with Affinity Propagation Algorithm
2008 Fourth International Conference on Natural Computation, 2008Analyzing notor imagery electrocardiogram (ECoG) signal is very challenging for it is hard to set up a classifier based on the labeled ECoG obtained in the first session and apply it to the unlabeled test data obtained in the second session. Here we propose a new approach to analyze ECoG trails in the case of session-to-session transfer exists.

Convergence Analysis of Affinity Propagation
2009Recently, Frey & Dueck proposed a novel clustering algorithm named affinity propagation (AP), which has been shown to be powerful as it costs much less time and reaches much lower error. However, its convergence property has not been studied in theory. In this paper, we focus on convergence property of the algorithm.

Mathematical analysis of affinity membrane chromatography
Journal of Chromatography A, 2005A mathematical model including convection, diffusion and Freundlich adsorption is developed. To examine the validity of the model, the affinity membranes were prepared by coating chitosan on the nylon membranes, a ligand of poly-L-lysine was bound to the chitoan-coating membranes, and the adsorption behavior of bilirubin through the stacked affinity ...

The Effect of Affine Transformation on Redundancy Analysis
Psychometrika, 1983Canonical redundancy analysis provides an estimate of the amount of shared variance between two sets of variables and provides an alternative to canonical correlation. The proof that the total redundancy is equal to the average squared multiple correlation coefficient obtained by regressing each variable in the criterion set on all variables in the ...

Affinity of Cefmenoxime for Beta-Lactamases: An Analysis
The American Journal of Medicine, 1984The interactions of cefmenoxime with beta-lactamases in comparison with cefotaxime, moxalactam, cefoperazone, and ceftazidime have been determined. On-line computerized microacidimetry allowed determination of the affinity of these compounds with the enzymes, which was characterized by Km values.

Affinity Biosensors for Tumor-Marker Analysis
Bioanalysis, 2014The use of cancer biomarkers is emerging as one of the most promising strategies for early detection and management of cancer. Biosensors can provide advanced platforms for biomarker analysis with the advantages of being easy to use, inexpensive, rapid and offering multi-analyte testing capability.

Analysis of biomolecular interactions using affinity microcolumns: A review
Journal of Chromatography B: Analytical Technologies in the Biomedical and Life Sciences, 2014 Affinity chromatography has become an important tool for characterizing biomolecular interactions. The use of affinity microcolumns, which contain immobilized binding agents and have volumes in the mid-to-low microliter range, has received particular ...

An affine invariant discriminate analysis with canonical correlation analysis
Neurocomputing, 2012Canonical correlation analysis (CCA) is invariant with regard to affine transformation, but it cannot be directly applied to affine invariant pattern recognition. The reason mainly lies in that many existing CCA-based schemes represent the pattern by matrix-to-vector method, as a result, the structure and spatial information of the original pattern is ...

Thrombosis Research, 1988
Binding affinity of fibrinolytic factors to insolubilized lysine and fibrin was quantitatively measured by frontal affinity chromatography using lysine-Toyopearl and fibrin-Sepharose column. The highest binding affinity was found with recombinant tissue-type plasminogen activator (t-PA), followed by lysyl-plasminogen and glutamyl-plasminogen (Glu-PLg ...
