Structure-Based Approximation Learning Theory: Under the description of manifold and topological architecture of neural field, we have proposed a learning frameworks of neural networks based on global architecture approximation theory borrowed from the concept of topology and manifold to solve the optimal problems of learning in non-nonlinear and non-Euclidean space, and discussed a few basic components of the learning theory, learning mechanism and learning algorithm in the term of structure-based approximation and global structure analysis.

For example, U-space is uniformly regular and which makes it has fixed point property, U-space is uniformly non-square and thus super-reflexive, uniformly convex space and uniformly smooth space are U-spaces, and an Banach space is an U-space iff its dual space is U-space, etc. In1990s, a lot of work had been done on U-space theory, e.g., Tingfu Wang and Donghai Ji introduced the concepts of pre U-property and nearly U-property. Under the structure of Orlicz space, they made systematic investigation of these properties, and gave the criteria for an Orlicz space to have U-property.

U-空间具有一致正规结构进而具有不动点性质；U-空间是一致非方的，进而也是超自反的；一致凸空间和一致光滑空间是U-空间；Banach 空间为U-空间的充要条件是其对偶空间为U-空间，等等。20世纪90年代，国内外学者对U-空间理论做了很多工作，王廷辅，计东海等人先后引入了准U-性质与似U-性质的概念，并在Orlicz空间框架下对有关性质进行了系统研究，完整给出了Orlicz空间具有各种U-性质的判据。

Alpha-1 antitrypsin is the most abundant circulating protease inhibitor in the body, Dr. Lomas said. Its most common deficiency mutation is the Z allele, where the amino acid lysine is exchanged for glutamic acid at position 342 in the polypeptide chain (Glu342Lys). About 1 in 1700 whites of northern European descent are homozygotes for this mutation and thus have plasma antitrypsin levels that are 10% to 15% below normal, he said.

In the second part of this thesis, a formal [2+2] cycloaddition ketenes and dialkyl azodicarboxylates was studied.

Jeff Goldblum: Oh, sure, I get a kick out of reading Mamet and he has some wicked and savage things to say about the materialistic world that is at least partly Hollywood, yeah, it's fun for me, those characters ripe to be make fun of in some way and looked at, X rayed.

杰夫·戈德布拉姆：噢，当然，在拜读梅米特的作品时偶就有一种非凡的快感，他对好莱坞内部的一些实物主意倾向进行了尖刻而猛烈的抨击。是的，这对偶而言是很愉快的，而且剧中那些角色个性偶也比较了解，拿他们来开玩笑确实很有趣，就像照X光似的。

The maximum coupling efficiency of the star styrene-butadiene rubber was 85.93%, obtained when the molar ratio of tin tetrachloride and active chains was 0.2625, tin tetrachloride was added in two portions and with the terminal styrene moiety exchanged for butadiene.
