Blumenthal, Donald K.; Underwood, Clayton J. | Adaptation of the protein kinase filter paper assay to a 96-well microtiter format. | The most widely used method for assaying protein kinase activities involves incorporation of radioactive phosphate into a protein or peptide substrate with subsequent binding or precipitaion of the radiolabeled substrate onto filter paper squares. We have adapted this assay for use with readily avai... | Protein Kinase Activities; Filter Papers; Radioactive Phosphate | 1999-02-01 |

Mathews, V. John | Adaptive algorithms for identifying recursive nonlinear systems | ABSTRACT This paper presents two fast least-squares lattice algorithms for adaptive non-linear filters equipped with system models involving nonlinear feedback. Such models can approximate a large class of non-linear systems adequately, and usually with considerable parsimony in the number of coeff... | 1991 | |

Mathews, V. John; Nilsson, Michael | Adaptive gain processing to improve feedback cancellation in digital hearing aids | Adaptive filters are commonly used to cancel acoustic feedback in hearing aids. The sound quality of hearing aids deteriorates as the hearing aid gain is increased. This paper presents a method to alter the gain function in digital hearing aids to provide additional amplification and better output ... | 2008 | |

Mathews, V. John | Adaptive gain processing with offending frequency suppression for digital hearing aids | Digital hearing aids identify acoustic feedback signals and cancel them continuously in a closed loop with an adaptive filter. This scheme facilitates larger hearing aid gain and improves the output sound quality of hearing aids. However, the output sound quality deteriorates as the hearing aid gai... | 2012 | |
