Abstract:

A method for obtaining a distribution of a stiffness property in tissue includes applying a plurality of loadings to the tissue, obtaining a plurality of two-dimensional (2-D) imaging projections of the tissue from different directions, measuring a force resulting from one of the plurality of loadings, measuring from at least one of the plurality of 2-D imaging projections a displacement of the tissue in response to the force, obtaining an initial set of input parameters for an estimated stiffness property of the tissue, and solving iteratively for the stiffness property using a computer.

International Classification:

C25D 9/02

US Classification:

205229, 205317

Abstract:

A method of forming a bioelectronic device including a protein on an electrically conductive substrate, by electrodepositing aminopolysaccharide chitosan on the substrate while applying a cathodic voltage to the substrate, to form an aminopolysaccharide chitosan film thereon, applying an anodic voltage to the substrate in the presence of NaCl to activate the aminopolysaccharide chitosan film so that it is reactive with protein. The method also optionally includes reacting the aminopolysaccharide film, after activation thereof, with the protein, so that the protein assembles on and is coupled to the substrate, thereby forming a bioelectronic device. The protein can include single or multiple protein species, and including biosensing proteins. Additional methods include biosensing of electrochemically active compounds either present in a sample or generated during a biological recognition event and devices useful in such methods. The resulting devices are useful as sensors in hand-held devices, textiles, garments and the like.

US Classification:

257/048000

Abstract:

A semiconductor wafer configured for in-process testing of integrated circuitry fabricated thereon. At least two die are separated by a scribe area, and each of the die has at least one complementary metal oxide silicon (CMOS) static random access memory (SRAM) array embedded therein among mixed-signal CMOS circuitry. The mixed-signal CMOS circuitry includes devices with larger feature sizes compared to similar devices of the embedded SRAM array. A first process control monitor (PCM) testline is included, which has a first layout corresponding to the mixed-signal CMOS circuitry. Additionally, a second PCM testline is included, which has a second layout corresponding to the embedded SRAM arrays. The first and second PCM testlines are formed in the scribe area.
