    摘要： A feedback cancellation system for a hearing instrument is described. The feedback cancellation system includes both a constrained adaptive filter, the constrained adaptive filter can be constrained by initiation coefficients, as well as an adaptive gain modification. The adaptive gain modification allows the feedback cancellation to respond to substantially different environments from the test environment used to derive the initiation coefficients for the constrained adaptive filter.

    摘要： A cell culture material comprising a sugar containing polymer in which at least one kind of sugar chain is bonded as a side chain via a spacer molecule is made into a three-dimensional shape whereupon a three-dimensional cell material is prepared. With regard to the sugar containing polymer, a sugar containing polymer having a carboxyl group such as alginic acid, hyaluronic acid, pectic acid or a derivative thereof is preferably used. Sugar chain having a specific recognition to a cell is bonded as a side chain and, therefore, when the cell is incubated using the cell culture material, it is possible to maintain and improve the proliferation, morphology and function of the cells and to retain the cell form in a form of near that in vivo due to a specific interaction between the cell and the sugar chain.

    摘要： The present invention provides a prosthetic heart valve comprising a stent, an alloy wire and biological tissue leaflets, the biological tissue leaflets being sewn to the alloy wire which is wrapped with a first polyester cloth, and the alloy wire being sewn to the stent which is wrapped with a second polyester cloth, wherein the stent is ring-shaped, comprising: a first stent layer and a second stent layer which are closely hooping with each other; the first stem layer being on the outside of the second stent layer, the first stent layer being made of a first material, the second stent layer being made of a second material, the first material and the second material being elastic, and the hardness of the second material being higher than that of the first material. Through the design of making the stent always tend to remain annular both in a stationary state and in a stressed state, the prosthetic heart valve of the present invention ensures the perfect match between the stent and the alloy wire, thereby increasing the stability of the entire valve and extending the service life of the valve.
