Gene sequence was highly homologic with a gene encoding aβ- subunit of ATP synthetase and an EST originating from a cDNA in relation to water deficit stress, which both were closely associated with the protein functioning in stress resistance and ion transportation. The results suggested that No. 1 gene sequence was involved in stress resistance of apple rootstock. No. 2 gene sequence had high homology with a gene encoding a serine/ threonine kinase protein, indicating perhaps it was a new gene encoding the serine/ threonine kinase protein in apple rootstock. The gene sequences of A1 and A2 were highly homologic with a gene encoding aβsubunit of ATP synthetase.

We initiated a genetic screen for Drosophila olfactory genes by means of SG18.1-Gal4/UAS system: The result validates our screen as an rapid, effective approach for recovering genes controlling glomerular map patterning; From a misexpression screen of 1,515 P{GS} lines, we identified 23 genes that, when forcibly expressed in the olfactory receptor neurons, disrupted the stereotyped anatomy of the Drosophila antennal lobes; These genes, which have not been shown previously to control olfactory map development, encode novel proteins as well as proteins with known roles in axonal outgrowth and cytoskeletal remodeling.

The processing unit of the architecture is independent of the codebook size that has an effect on encoded image quality, and can easily be extended to an arbitrary number of codewords without increasing extra hardware for computing, which is superior in enlarging codebook size to improve reconstructed image quality.

It contains 215 bp, named as ZM908. Biosoftware anlysis sug gests that ZM908 gene properly belongs to the mRNA-like non-coding RNA gene which is purposed to lack of obvious open reading frame (the longest possibly contains 98 AA), contain poly tale and have stable RNA structure in vivo. ZM908 contains high conserved nucleotide sequence with ZM401 (including 371-598bp, 698-847bp and 929-1047bp in ZM908). The highest conserved sequence reaches 86%.The RT-PCR analysis result revealed that ZM908 is transcriptable.

But when cognitive resources are limited ,the encoding of consistent information is better than the encoding of inconsistent information, because perceivers haven't enough capacity to carry out "inconsistency resolution" and meantime stereotype provides conceptual fluency for consistent information.

Sherman等人(1998年)的实验就表明，虽然就概念编码而言，对一致性信息的加工优于对不一致性信息的加工；但是就知觉编码而言，对不一致性信息的加工优于对一致性信息的加工。本文在理论分析及总结大量研究成果的基础上，对Sherman的观点进行了加工、补充和深化从而形成了刻板印象功效的&灵活编码模型&。

Conventional video compression algorithms have higher compressibility, but the output code stream still needs recoding. A selfadapting arithmetic encoder was required in practical application to produce a final code stream, which can eliminate redundancy in binary code stream to obtain higher encode efficiency. QM arithmetic encoder is a high efficiency encoder designed for the simplicity and speed.
