\\ rank(A-AB)\le rank(A(I-B))=min\left\{rank(A),rank(I-B)\right\}\le rank(I-B) 因此不等式成立。 6.已知矩阵 A,B ,且满足 AB=BA=0, rank(A^2)=rank(A) ,试证明: \\ rank(A+B)=rank(A)+rank(B) 证明一: 由4的结论我们知道,只需要证明 rank(A+B)\ge rank(A)+rank(...
In this paper we use rank information to construct a measure of preference satisfaction by collective decision rules and to compare the Borda rule with the plurality rule with respect to the inequality their outcome induces. While the construction of our measure of preference satisfaction is formally...

在本文中,我们介绍了一种称为 Lero 的 learning-to-rank 查询optimizer,它建立在本地查询优化器之上,并不断学习提高优化性能。关键观察是计划的相对顺序或排名,而不是确切的成本或延迟,足以进行查询优化。Lero 采用成对方法训练分类器来比较任意两个计划并判断哪个更好。在模型效率和准确性方面,这种二元分类任务比...
抗原结合分子是单价抗原结合分子(例如,fab、scfab、fab'、scfv、单臂抗体等)。 26.抗原结合分子合适地包括以下活性中的任一种或更多种:(a)抑制rankl与rank的结合;(b)抑制rank活化;(c)抑制下游rank介导的分子信号传递(例如,rank募集traf蛋白);(d)抑制rank多聚化;(e)减少破骨细胞分化;(f)降低破骨细胞活化;(...

This line was then crossed into Rankflox/flox mice to examine Brca1 deletion-induced tumorigenesis in the presence or ab- sence of RANK expression (Supplementary information, Figures S1A, S1B and S2). All mouse lines examined appeared to develop normal mammary glands at puberty. In 4-month-...

\,\le \,n+1. \end{aligned}$$ (1.3) here n ( a ) denotes the kernel of the linear relation a , that is, the set of all \(x\in x\) such that \(\{x,0\}\in a\) . if, in addition, \(a\subset b\) or \(b\subset a\) , we show that the left-hand side in ( ...
It identifies the lattices of two-sided closed ideals of A and B and furthermore, preserves weak containment and direct integrals. 1.1 Description of the main result We bring together the two themes above in the case where (G, H ) is an equal rank dual pair of the form (M p2n, O2n...
