unkown
1.Detection of an unkown peak at 1.2 ppm in proton magnetic resonance spectra of cats with cerebral ischemic necrosis
2.Methods A unkown sample in a case was analyzed with FTIR、SEM/EDX、GC/MS and chemical methods.
3.The unkown receptor of 4IgB7-H3 on activaton T cells was detected by the fusion protein with FACS,and the costimulatory effection to T cell was measured by MTT.
4.(1) a very few P73 gene occur mutation (2) in the most stat, it is di - allele Expression and on some unkown Conditions it is mono - allele.
5.Results48/97(49.5%) of cases was bacteremia due to CNS. 24 strains (50.0%) were related to catheters using and foreign bodies, 8 (16.7%) related to postoperative wounds, 5(10.4%) related to breath way, 5(10.4%) related to umbilicus, 1 related to eye infection. The rest 5 strains were unkown.
6.In this paper, the author discusses Bahadur asmptotic efficiency on the estimation of β , which is an unknown parameter vector in the partly linear model Y i=X T iβ+g(T i)+ε i. i=1,2,…,n , where g is an unkown H?o??lder continuous function. ε i is a random error, ｛(X i,T i), i=1,2,…,n｝ is a sequence of known design points.
