摘要:
Systems and methods are provided for decoding a vector from a communications channel using a non-binary decoder. The communications channel may correspond to a wired or wireless channel. A message passing process computes R messages corresponding to a variable node of the non-binary decoder. Decoder extrinsic information is formed for the variable node by combining the R messages. The decoder extrinsic information is provided to a soft-detector.

Systems, methods, and other embodiments associated with an encoder. In one embodiment, a system includes an encoder having a code word generator and an appending logic. The code word generator is configured to generate code words based on input data and identify one or more short code words. A short code word has a length less than a length of a full code word. The appending logic is configured to append at least one dummy value to at least one of the short code words to convert the at least one short code word to a full code word. The encoder may further be configured to encode the converted full code word and store the converted full code word without the at least one dummy value in a storage medium.
摘要:
Functionalized magnetic particles are emerging as a reliable and convenient technique in the purification of biomacromolecules (proteins and nucleic acids). We disclose a novel coupling procedure that can be used to create stable ferromagnetic nickel particles coated with Protein A for the affinity purification of antibody. The protein purification procedure is gentle, scalable, automatable, efficient and economical. By modifying the functional groups of amino acids in the protein coating, nickel particles can be used not only for affinity purification but for other sample preparation and chromatographic applications as well including nucleic acid isolations. The method can be easily modified for small and medium scale antibody purification in lab and pre-clinical research.
摘要:
An optical navigation system and method for performing self-calibration on the system uses captured frames of image data of an interior surface of a calibration cover of the system to detect a performance-related change of the system. In response to the detected performance-related change, a predefined procedure is then initiated.
摘要:
A reference image of an area of a print media is captured at approximately a first time by an image acquisition system. A first application of ink is applied onto the print media area by a printing assembly at the first time. A comparison image of the print media area is captured at a second time by the image acquisition system subsequent to the first application of ink onto the print media area. The reference image and the comparison image are processed to determine a relative displacement of a feature pattern on the print media between approximately the first time and the second time. A second application of ink from the printing assembly onto the print media is adjusted based on the determination.

The invention provides highly concentrated chitosan-nucleic acid polyplex compositions and dispersions, and methods for producing the compositions and dispersions. Methods of mixing the chitosan-nucleic acid polyplexes include an inline mixing of chitosan solution and nucleic acid solution, followed by further concentrating the dispersion of chitosan-nucleic acid polyplexes, optionally with an aggregation inhibitor. Further provided are methods for altering the diameter of chitosan-nucleic acid polyplexes.

A nanoimprint mold includes a substrate having at least one substantially non-transferable feature and at least one transferable feature defined at different portions thereon. Methods for forming the same are also disclosed.
摘要:
An imprint apparatus and method employ an effective pressure in imprint lithography. The imprint apparatus includes a compressible chamber that encloses an imprint mold having a mold pattern and a sample to be imprinted. The chamber is compressed to imprint the mold pattern on the sample. The mold is pressed against the sample with the effective pressure. The effective pressure is controlled by a selected ratio of a cavity area of the chamber to a contact area between the mold and the sample.
摘要:
A method is disclosed for creating hydrogels with ordered crystalline structures that exhibit a characteristic colored opalescence. In addition to the unique optical properties, these materials contain a large amount of water in their crosslinked networks. The manufacturing processes include synthesizing monodispersed hydrogel nanoparticles containing specific reactive functional groups, self-assembly of these particles to form a crystalline structure, and subsequent crosslinking neighboring spheres to stabilize the entire network. Polymerizing a hydrogel monomeric composition around the crystalline structure can enhance the mechanical strength. The resulting network is dimensionally and thermodynamically stabile under various pH and temperature conditions. The color and volume of these crystalline hydrogel networks can reversibly change in response to external stimuli such as temperature, pH and other environmental conditions. These new materials may lead to a variety of technological and artistic applications, ranging from sensors, displays, controlled drug delivery devices, jewelry and decorative consumer products.
