Abstract: A parallel iterative decoding system interposed between a network interface and a block memory matrix receives encoded data and both stores the data in a First-In-First-Out (“FIFO”) memory block and processes it through a timing recovery engine. The timing recovery engine delivers to an iterative decoder synchronized data samples and detects cycle slip. The iterative decoder thereafter performs a predetermined number of iterations to decode the data. Responsive to encoded data failing to converge after the predetermined number of iterations, the encoded data is communicated from the FIFO memory to an auxiliary decoder module. The auxiliary iterative error correction code decoder performs a second predetermined number of iterations to decode the data wherein the number of iterations performed by the auxiliary iterative error correction code decoder is greater than the primary iterative error correction code decoder.

Abstract: An exemplary heat dissipation device includes mounting feet and fasteners mounted on the mounting feet. Each fastener includes a shaft and two latching portions extending outwardly from an outer circumference of an end of the shaft. Each mounting foot defines a through hole allowing extension of the end of the shaft with two second portions. Each mounting foot defines two latching recesses in a surface thereof. Each of the latching recesses defines two blocking surfaces. When the end of the shaft with the latching portion extends through the through hole and beyond the surface of a corresponding mounting foot, the shaft is rotated with respect to the through hole so as to make the latching portion be received in the latching recesses. The blocking surfaces of the latching recesses stop the latching portions rotating with respect to the through hole to escape from the corresponding mounting foot.

Abstract: A method of writing data to and reading data from a storage medium includes cycle slip detection and correction. An LDPC matrix includes a first area for cycle slip detection and correction. The first area satisfies a set of conditions such that a cycle slip at a particular position creates a pattern of parity check errors indicative of the position and polarity of the cycle slip. Writing user data to the storage medium includes encoding the user data with parity data according to the LDPC matrix. Reading the user data and the parity data from the storage medium includes decoding the user data and the parity data according to the LDPC matrix. Decoding includes, upon detecting a pattern of parity check errors indicative of the position and polarity of a detected cycle slip, correcting the detected cycle slip.

Abstract: Antibody expression vectors and plasmids can incorporate various antibody gene portions for transcription of the antibody DNA and expression of the antibody in an appropriate host cell. The expression vectors and plasmids have restriction enzyme sites that facilitate ligation of antibody-encoding DNA into the vectors. The vectors incorporate enhancer and promoter sequences that can be varied to interact with transcription factors in the host cell and thereby control transcription of the antibody-encoding DNA. A kit can incorporate these vectors and plasmids.

Abstract: Methods and apparatuses for removing polysilicon material from a semiconductor workpiece are disclosed. A particular method includes contacting a polishing pad with a semiconductor workpiece having a surface polysilicon material. The method also includes disposing a polishing liquid between the polysilicon material and the polishing pad. The polishing liquid contains an oxidizer that does not include metal elements. The method further includes moving at least one of the semiconductor workpiece and the polishing pad relative to the other while the semiconductor workpiece contacts the polishing pad and the polishing liquid. At least some of the polysilicon material is removed while the polysilicon material contacts the oxidizer in the polishing liquid, as at least one of the semiconductor workpiece and the polishing pad moves relative to the other.

Abstract: Timing recovery circuitry for a digital subscriber line (DSL) modem, including a combined frame and timing function for adjusting frame alignment, and for adjusting sample frequency for frequency offset and for phase offset. Frame alignment is adjusted by averaging estimates of the phase offset over multiple tones within a frame, and then averaging that average estimated phase offset over multiple frames to produce a frame offset measurement. Frequency offset is derived from the constant rate of phase error variation in the received signal varies over a sequence of frames, based on which the sample frequency of the modem is adjusted. Phase offset is determined by averaging the phase offset over a plurality of tones within a frame, and integrating differences in this phase offset from frame to frame.

Abstract: Described and claimed herein are combinatorial synthetic Fab libraries displayed on a phage pIX protein. The libraries were built on scaffolds representing the most frequently used genes in human antibodies, which were diversified to mirror the variability of natural antibodies. After selection using a diverse panel of proteins, numerous specific and high-affinity Fabs were isolated. By a process called in-line maturation the affinity of some antibodies was improved up to one hundred-fold yielding low pM binders suitable for in vivo use. This work thus demonstrates the feasibility of displaying complex Fab libraries as pIX-fusion proteins for antibody discovery and lays the foundations for studies on the structure-function relationship of antibodies.

Abstract: Timing recovery circuitry for a digital subscriber line (DSL) modem, including a combined frame and timing function for adjusting frame alignment, and for adjusting sample frequency for frequency offset and for phase offset, is disclosed. Frame alignment is adjusted by the frame and timing function by averaging estimates of the phase offset over a plurality of tone pairs within a frame, and then averaging that average estimated phase offset over a plurality of frames to produce a frame offset measurement. Frequency offset is derived by analyzing the extent to which phase error in the received signal varies at a constant rate over time, specifically over a sequence of frames; the sample frequency of the modem is adjusted in response to the detected frequency offset. Phase offset is determined by averaging the phase offset over a plurality of tones within a frame, and integrating differences in this phase offset from frame to frame.
