Abstract: A method includes receiving a codeword over a communications channel and initializing a test codeword to be equal to the codeword received over the communications channel. The method includes performing, for each row of a low-density parity check (LDPC) matrix, an LDPC processing operation on the test codeword. The method includes, once the LDPC processing operations have been performed for all of the rows of the LDPC matrix, repeating the LDPC processing operations. The method includes monitoring progress of the LDPC processing operations. The method includes selectively generating a termination signal in response to the test codeword being a valid codeword according to the LDPC matrix. The method includes terminating the LDPC processing operations in response to generation of the termination signal.

Abstract: A data encoding system includes a data encoder circuit operable to encode each of a number of data sectors with a component matrix of a low density parity check code matrix and to yield an output codeword. The data encoder circuit includes a syndrome calculation circuit operable to calculate and combine syndromes for the data sectors.

Abstract: An apparatus for decoding data includes a variable node processor, a check node processor, and a field transformation circuit. The variable node processor is operable to generate variable node to check node messages and to calculate perceived values based on check node to variable node messages. The check node processor is operable to generate the check node to variable node messages and to calculate checksums based on variable node to check node messages. The variable node processor and the check node processor comprise different Galois fields. The field transformation circuit is operable to transform the variable node to check node messages from a first of the different Galois fields to a second of the Galois fields.

Abstract: Methods and compositions are described whereby poorly water-soluble beneficial agents such as vitamins and co-factors are formulated into self-emulsifying formulas (SEF) and optionally sorbing the SEF into pores of porous solid particulates, or preparing supersaturated solutions (SSS) and sorbing the SSS into pores of porous solid particulates. These formulations are useful as dosage forms with oral availability.

Abstract: The present disclosure includes systems and techniques relating to decoding signals produced within a storage device. A described technique includes retrieving a first codeword from a storage medium, decoding the first codeword, performing a retry process when the decoding was not successful, and retrieving one or more second codewords from the storage medium during the retry process to at least maintain a drive throughput. The retry process can include identifying one or more data chunks within the first codeword having potential defects, generating an erasure mask based on the one or more data chunks, applying, based on a window, one or more erasures within one or more different regions of the first codeword based on one or more corresponding regions of the erasure mask to produce one or more versions of the first codeword, and decoding the one or more versions of the first codeword.

Abstract: Disclosed are two myocardial peptides, whose amino acid sequences are Trp-Ser-Asn-Val-Leu-Arg-Gly-Met-Gly-Gly-Ala-Phe and Lys-Gly-Ala-Trp-Ser-Asn-Val-Leu-Arg-Gly-Met-Gly-Gly-Ala-Phe respectively, wherein the latter can be obtained by extracting from myocardial peptides solution. The myocardial peptides can be used in the produce of a medicament for preventing and/or treating myocardial ischemia.

Abstract: An auto tools change with space allowance for tool rejection of spindle includes an arm seat, an arm shaft, a tools change arm, a flat cam, and a driving arm, while the flat cam has a driving groove for driving the driving arm to swing and thus facilitates the tool clamping and tool unclamping. Therein, the driving arm has a tool clamping section having an allowance groove, a first transition section, a tool unclamping section, and a second transition section. Therefore, a larger width of the allowance groove is provided on the driving groove, thereby offering a sliding space for the tools change arm. Thus, a space allowance is produced during tool pushing process, thereby not only preventing the main shaft and the tool from being damaged, but also preventing the tools change arm from deformation.
