Researchers reject fetal tissue banks

Adaptive controller using filter banks to reject multi-sinusoidal disturbance

The purpose of this paper is to apply "lter banks to the control problem involving the rejection of multi-sinusoidal disturbance from output of slowly time-varying stable systems. The use of "lter banks allows to distribute the control e!ort in many independent adaptive controllers, each of them taking care of a sinusoidal component of the disturbance. By varying the "lter banks speci"cations, ...

Extracting tissue deformation using Gabor filter banks

This paper presents a new approach for accurate extraction of tissue deformation imaged with tagged MR. Our method, based on banks of Gabor filters, adjusts (1) the aspect and (2) orientation of the filter’s envelope and adjusts (3) the radial frequency and (4) angle of the filter’s sinusoidal grating to extract information about the deformation of tissue. The method accurately extracts tag lin...

Tissue banks trigger worry about ownership issues.

Tissues have what a new generation of researchers need to fi ght cancer: molecular clues to disease origins and a wealth of potential targets for new drugs. But some National Cancer Institute leaders consider a potential shortage of human tissues the single greatest barrier to cancer research. Now, with high-throughput, robotic systems analyzing tissue samples by the thousands, shortages have b...
