摘要： A bioprosthetic valve graft comprises a valve frame and valve flaps, the latter acting to open or close a valve aperture to directionally control fluid flow through the bioprosthesis. The bioprosthetic valve graft comprises method for suturelessly attaching a biomaterial suturelessly bonded to the A method for securing a biomaterial to a valve frame includes positioning a flexible valve frame defining an open area on a first major surface of a biomaterial sheet having a peripheral edge, wherein positioning serves to approximate the valve frame and the peripheral edge of the biomaterial sheet to form an at least first bonding locus: and suturelessly bonding the biomaterial to the valve frame at the at least first bonding locus. The method avoids the disadvantages associated with conventional sutures and substantially reduces medical complications in implantations.

摘要： The present invention provides an absorbent wound dressing assembly that can be used to stanch, seal, or stabilize a site of tissue injury, tissue trauma, or tissue access. The wound dressing assembly is flexible so that it can be adapted and used to fit in narrow and small wound sites. Generally the wound dressing assembly comprises a flexible carrier material that is impregnated with a non-mammalian material for control of severe bleeding. The preferred non-mammalian material is poly [β-(1→4)-2-amino-2-deoxy-D-glucopyranose] more commonly referred to as chitosan.

摘要： Methods and systems for measuring mechanical property of a vascular wall and a method and system for determining health of a vascular structure are provided wherein local deformation of a vessel wall resulting from physiologic pressures with altered transmural forces is measured. A non-invasive free-hand ultrasound scanning-procedure was performed to apply external force, comparable to the force generated in measuring a subject's blood pressure, to achieve higher strains by equalizing the internal arterial baseline pressure. When the applied pressure matched the internal baseline diastolic pressure, strain and strain rate increased by a factor of 10 over a cardiac cycle. Radial arterial strain was assessed in the vessel wall over the entire deformation procedure using a phase-sensitive, two-dimensional speckle-tracking algorithm. An elastic modulus reconstruction procedure was developed to estimate the non-linear elastic properties of the vascular wall.

摘要： Searching multimedia information which allows determining preferences based on very little amounts of data. The preferences are nonparametrically determined. Each preference is quantized into one of a plurality of bins. By doing the quantization, the distances between positive and negative samples are increased. The quantization amount may change depending on the number of samples which are used. The quantization can be used in a support vector machine or the like.
