In this paper, a person tracking sensor based multi-channel audio panning approach is proposed for multi-view broadcasting services. Multi-view broadcasting is realized by rendering the video sequences captured by a set of cameras from different viewpoints. In addition, a multi-channel audio panning technique is required for realistic audio rendering. Moreover, person-tracking techniques for es...

We consider the problem of searching through visualizations of large amounts of data by performing panning and zooming operations. We give algorithms to travel from a source to an unknown target using a number of pans and zooms that is competitive with the optimal number of pans and zooms depending on certain parameters, and consider both the one-dimensional and two-dimensional versions of this...

Tumor-targeted therapies are playing growing roles in cancer research. The exploitation of these powerful therapeutic modalities largely depends on the discovery of tumor-targeting ligands. Phage display has proven a promising high throughput screening tool for the identification of novel specific peptides with high binding affinity to cancer cells. In the present study, we describe the use of ...

Objectives B cell-mediated immunity can be associated with favorable clinical outcomes in cancer patients. However, the mechanism and features of anti-tumor immune responses are not well understood. In particular, how cells expressing tumor-specific antibodies distributed (in tumor vs. circulation) has been defined. Methods We performed an in-depth analysis cell antibody repertoires derived fro...

This paper introduces a novel technique for smooth and efficient zooming and panning based on dynamical systems in hyperbolic space. Unlike the technique of van Wijk and Nuij, the animations produced by our technique are smooth at the endpoints and when interrupted by a change of target. To analyze the results of our technique, we introduce world/screen diagrams, a novel technique for visualizi...

A mathematical model is presented to objectively derive sound localisation performance using HRIR (Head Related Impulse Response) based binaural sound reproduction systems. Rendering a sound source via panning methods causes artefacts that will lead to errors in localisation by human subjects. A localisation function and a localisation blur will be derived by comparing reference HRIRs with the ...

By using a chromogenic substrate for an ubiquitous lysosomal enzyme, hexosaminidase to estimate cell numbers, a sensitive and simple procedure has been developed in which microtiter reaction wells are directly scanned in a spectrophotometer. This method has been adapted to several cell biological assays. Quantitation of the biological activities of T cell growth factor and interferon can be per...
