    摘要： A method for operating a receiver is disclosed. The receiver may receive, over a channel from a transmitter, a first data bit at a first period of time. The receiver may receive, over the channel, a second data bit at a second period of time subsequent to the first period of time. The first and second data bits each have either a first logical value corresponding to a voltage greater than zero volts or a second logical value corresponding to a voltage less than or equal to zero volts. The receiver performs a coefficient adaptation operation, using the first data bit, to adjust one or more coefficients of a decision feedback equalizer of the receiver only when the logical value of the first data bit is equal to the logical value of the second data bit.

    摘要： As disclosed herein, novel compositions including steroid hormones, such as trimegestone (TMG) and progesterone (P4), provide treatments for term and preterm labor with significant effects on the delay of delivery. Delay and block of delivery occurs when both P4 and TMG are administered late in gestation in pregnant rat and guinea pig animal models. TMG exhibits remarkable drug efficacy, achieving the same inhibition as P4, but at much lower doses. These hereto unknown effects of TMG on the processes of cervical ripening and uterine contraction provide a novel approach for extending pregnancy term, including reducing a likelihood of preterm and/or term labor, along with improved methods of administration. Other diseases and/or conditions may be treated with TMG, such as dysmenorrhea or luteal insufficiency for sustaining pregnancy.

    摘要： Computer graphics may be detected in digital images by extracting a first set of features from an input digital image, extracting a second set of features from a prediction-error image derived from the input digital image, and applying a classification algorithm to the first set of features and the second set of features to determine if the combined sets of features indicate that the input digital image corresponds to computer graphics.

    摘要： Methods and apparatus are provided for subjecting an original, pixel domain image to an Integer Wavelet Transform (IWT) to obtain a matrix of wavelet coefficients; selecting at least one bit plane between a least significant bit plane and a most significant bit plane of the matrix of wavelet coefficients; compressing the at least one selected bit plane to produce free space in the at least one selected bit plane; embedding hidden data in the free space of the at least one compressed bit plane; and subjecting the at least one embedded bit plane to an Inverse IWT to produce a marked pixel domain image. Methods and apparatus are also provided for reversing this process.
