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.
Lomas博士表示,甲一型抗胰蛋白酵素是身体内最充分的循环蛋白酶抑制剂,最常见的缺损突变在Z对偶基因,该处的胺基酸 lysine与麸氨酸在多胜肽链的第342位置交换(Glu342Lys);北欧血统白人每1,700人有1人是此一突变的同合子,因此血浆抗胰蛋白酵素值比正常低10%到15%。
