Abstract: Disclosed herein are compositions and methods to treat skin with a peracid-based benefit agent. The peracid benefit agent can be used for a benefit such as the prevention or treatment of acne, skin whitening, skin bleaching, skin conditioning, reducing the appearance of skin wrinkles, skin rejuvenation, reducing dermal adhesions, and preventing, reducing or eliminating body odors or any combination thereof. The peracid may be enzymatically generated from a carboxylic acid ester substrate using an enzyme having perhydrolytic activity (perhydrolase) in the presence of a source of peroxygen. A fusion protein comprising the perhydrolase coupled to a skin-binding domain, either directly or through an optional linker, may be used to target the perhydrolytic activity to the skin surface.

The stable adduct dispersion can be used to durably apply a particulate benefit agent to a body surface.

Abstract: Disclosed herein are compositions and methods to treat hair with a peracid-based benefit agent. The peracid benefit agent can be used for hair bleaching, hair weakening, hair removal, hair waiving, hair straightening or any combination thereof. The peracid may be enzymatically generated from a carboxylic acid ester substrate using an enzyme having perhydrolytic activity (perhydrolase) in the presence of a source of peroxygen. A fusion protein comprising the perhydrolase coupled to a hair-binding domain, either directly or through an optional linker, may be used to target the perhydrolytic activity to the hair surface.

More specifically, a pH stabilized two component system is provided comprising (a) a first aqueous composition comprising hydrogen peroxide and at least one carboxylic acid ester substrate; wherein the pH of the first aqueous composition is 4.0 or less and (b) a second aqueous component comprising an enzyme catalyst having perhydrolytic activity and a buffer, wherein the pH of the second aqueous composition is at least 5.0; wherein the first and second aqueous compositions remain separated until use. The perhydrolytic enzyme catalyst may be in the form of a fusion protein comprising a perhydrolytic enzyme coupled through an optional peptide linker to a peptidic component having affinity for hair.

Abstract: Microparticle-based analytical methods, systems and applications are provided. Specifically, the use of resonant light scattering as an analytical method for determining either or both a particle's identity and the presence and optionally, the concentration of one or more particular target analytes is described. Applications of these microparticle-based methods in biological and chemical assays are also disclosed.

Abstract: In one embodiment of the invention, an error-correcting receiver includes an input buffer for storing received codewords, a first error correction syndrome circuit coupled to receive a first codeword and produce an output word, and a second error correction syndrome circuit coupled to receive a second codeword and produce an output word. An error-trapping-and-decoding circuit alternately receives the output words of the first and second error correction syndrome circuits. An error correction circuit coupled to the error-trapping-and-decoding circuit and the input buffer is adapted to provide corrected codewords.

Abstract: Method and system for generating a multiple width (e.g., 16-bit width) pseudo-random number (PRN). Each of first and second 8-bit width PRNs is generated, using first and second LFSR configurations that incorporate first and second characteristic polynomials, at least one of which is irreducible. The first and second 8-bit PRNs are generated on a rising edge and on a falling edge, respectively, of a clock signal. The first and second 8-bit PRNs are combined by concatenation or by interleaving to form a 16-bit, or other multiple width, PRN.

Abstract: High speed CML logic gate systems for providing selected Boolean logic functions. Two halves of a substantially symmetric first system, having a relatively small number (14) of CMOS transistors, are used to generate any of the logic functions AND, NAND, OR and NOR. Two halves of a substantially symmetric second system having another small number (10) of transistors are used to generate any of the logic functions XOR, XNOR and NOT. In either system, the sum of currents passing through certain voltage-controlling gates is substantially constant.

Abstract: One aspect of the present invention relates to a method of creating patterned composite structures on a surface via layer-by-layer deposition of thin films. In certain embodiments, the surface is chemically patterned by the direct stamping of functional polymers on the surface film. A pattern may then be used as a template for the further depositions of materials on the surface. This concept may be applied to various functional polymer and substrate systems as well as various thin film deposition techniques.
