By a modification of the technique developed by He et al., one can express the unknown syndromes as functions of the known syndromes. The unknown syndromes are determined by an efficient algorithm also developed in this paper. With the appearance of unknown syndromes, one obtains the consecutive syndromes that are needed for the application of the Berlekamp-Massey algorithm. The decoding scheme, developed here, is easier to implement than the previous decoding algorithm developed for the Golay code and the (47, 24, 11) QR code. Moreover, it can be extended to decode all codes of the family of binary quadratic residue codes with irreducible generating polynomials.

To date, the use of rib cartilage for auricular reconstruction is one of the most enduring and ubiquitous techniques for microtia reconstruction as it provides excellent aesthetic results with lasting durability. In this review, the authors outline the most common methods of microtia reconstruction with a comparison of each technique and illustrative case examples.

Within its enclosure, the frontal sinus lies adjacent to many important intracranial structures, and injury to this region has severe complications if not properly managed. Historically, the goals of frontal sinus fracture management have been to best prevent intracranial complications with invasive procedures, but a recent shift favoring conservative management now aims to preserve the form and function of the frontal sinus and its outflow tract. With the advancement of endoscopic techniques and the development of new technologies, many alternatives to aggressive surgical management are available.

A working understanding of evaluation, assessment, management, and prevention of further injury when dealing with these fractures is vital. This two-part series detailing the management of midface fractures serves as a guide for the appropriate workup and management of the wide variety of fracture patterns that are commonly encountered.

This MO multiplier is very effective in performing the inverse element or exponentiation of a finite field element on the normal basis. This design focuses on the space reduction and law delay of the previous ones. The delay of this multiplier is fried and independent of m. Due to its regularity and simpliciq, the design and expansion to a high-order finite-field multiplier is much easier to realize. Keyword: Massey-Omura multiplier, Finite field, VLSI, all-one polynomial, optimal normal bases.

By applying a technique developed in He et al. [2001], one can express unknown syndromes as functions of known syndromes. Unknown syndromes are determined by an efficient algorithm also developed in this paper. With the experience of unknown syndromes, one obtains the consecutive syndromes that are needed for the application of the inverse-free BM algorithm. The new decoding scheme, developed here can be used to implement the (71,36,11) QR code which has not been treated so far. It is verified by a computer program that uses the C++ language.

In optical experiments we observe an acoustically induced switching of the occupancy of the nanostructures along with an overall increase of the emission intensity. For quantum posts, switching occurs continuously from predominantly charged excitons (dissimilar number of electrons and holes) to neutral excitons (same number of electrons and holes) and is independent of whether the surface acoustic wave amplitude is increased or decreased. For quantum dots, switching is nonmonotonic and shows a pronounced hysteresis on the amplitude sweep direction. Moreover, emission of positively charged and neutral excitons is observed at high surface acoustic wave amplitudes. These findings are explained by carrier trapping and localization in the thin and disordered two-dimensional wetting layer on top of which quantum dots nucleate. This limitation can be overcome for quantum pos...

Observations using a vector vortex coronagraph have given us direct detections of the two-ring dusty debris system around the star HD 141569. Our observations reveal the inner clearing in the disk to unprecedentedly small angular separations, and are the most sensitive yet at the H and K bands. We are for the first time able to measure and compare the colors of the scattered light in the inner and outer dust rings, and find that the outer ring is significantly bluer than the inner ring.
