Abstract: A decoding method and device are provided. The spectrum parameter of a current bad data frame is determined. Specifically, a number of continuous bad frames that occur currently is determined. A spectrum parameter of a good data frame before the current bad data frame is determined. And a constant mean value of a spectrum parameter is determined. Then, the spectrum parameter of the good data frame is adaptively shifted towards the constant mean value of the spectrum parameter according to the number of the continuous bad data frames to calculate and obtain spectrum parameter information of the current bad frame. When the continuous bad data frames occur, the relevance between the spectrum parameter of the nearest good frame and the spectrum parameter of the current bad frame is gradually reduced, so that more accurate spectrum parameter of the current bad data frame can be obtained, thereby obtaining a better speech quality under a same code rate and a same frame error rate.

Abstract: Proteins with Hyp-glycosylation are more likely to be secreted in plant cells at high levels than those without. Methods are disclosed for the prediction of Pro-hydroxylation and Hyp-glycosylationsites in proteins. Such methods can be used to identify (1) proteins which, without modification, are predisposed to develop Hyp-glycosylation, if expressed in plant cells, and (2) modifications (especially substitution mutations) which increase the propensity of a protein to develop Hyp-glycosylation, with a view to high level or increased secretion. It is also possible to determine empirically whether a particular protein will undergo Hyp-glycosylation suitable for the desired level of secretion in plant cells. Both modified proteins, and methods for the expression and secretion of predisposed and modified proteins, are claimed.

Abstract: The invention relates to a video encoding and decoding technical field of the signal processing, especially relates to a method for video clip assisted by clip identifier. The method defines a clip identifier on the video encoding and decoding rule as an identifier used specially for video stream clip. If the encoded video bit stream is clipped, then said clip identifier is inserted to the bit stream or used to replace the original identifier which functions as a start flag. The clip of the video bit stream can be operated conveniently by the invention. The features of the invention are: the bits, which mark whether the clipped video bit stream may be decoded and displayed incorrectly or not, are not required to appear in the unclipped bit stream; if it clips at a certain point of the bit stream, then said identifier will appear at this point to indicate that a problem in which the picture can not be decoded normally due to the predictive reference data being clipped may appear.
