1 0 2 0 1 1 (a) Suppose a2 = (1, 2, 2) , a3 = (−2, 0, 1) , a4 = (0, 4, 5) , a5 = (0, 1, 1) . Compute the ranks of A and B. Explain why B can not be obtained from A by a finite number of elementary row operations. Solution: The first 3 columns of B are independent, so its column space has dimension 3, thus rank(B)=3. The second, third and fifth column of A are independent, so its column space ha...

Binding sites for high molecular weight kininogen (HK) and for factor XIIa are present in the Apple 1 (A1) and the A4 domains of factor XI, respectively. To define the roles of these two sites in surface-mediated factor-XI activation we prepared conformationally constrained synthetic peptides and recombinant A1 domain (rA1) and determined their effects on the activation of factor XI by factor X...

HOX A genes are induced in a temporal fashion after retinoic acid (RA) treatment in non-N-ras-transformed PA-1 human teratcarcinoma cells. However, In N-ras-transformed PA-1 cells, RA-Induced expression of HOX A genes is delayed. The mRNA for the transcriptional activator AP-2 is overexpressed in these ras-transformed cells, but AP-2 transcriptional activity is inhibited relative to non ras-tra...

Soluble vascular cell adhesion molecule-1 (sVCAM-1) is generated during inflammation and can alter lymphocyte functions. The authors report that the binding of sVCAM-1 to a4 integrinbearing cells is a dynamically regulated, active cellular process. Binding of recombinant sVCAM-1 to a4 integrins on peripheral blood mononuclear cells was celltype specific. Circulating CD161 NK cells constitutivel...

Objective To study the structural relationship between annexin A4 and the Lewis y antigen and compare their expression and significance in ovarian clear cell carcinoma, and to explore how annexin A4 fucose glycosylation effects the interaction between annexin A4 and NF-kB p50, and how it promotes tumour progression of ovarian clear cell carcinoma. Methods Structural relationships between anne...

Multipotential FDCP-Mix A4 (A4) cells can be induced either to self-renew or to differentiate and develop into mature neutrophils in liquid culture, depending on the haemopoietic growth factors with which they are cultured. When cultured in low concentrations of interleukin 3 (IL-3, 1 unit/ml)) plus Granulocyte Macrophage Colony Stimulating Factor (GM-CSF) and Granulocyte-CSF (G-CSF), A4 cells ...

The leptonic Higgs doublet model of neutrino masses is implemented with an A4 discrete symmetry (the even permutation of 4 objects or equivalently the symmetry of the tetrahedron) which has 4 irreducible representations: 1, 1, 1, and 3. The resulting spontaneous and soft breaking of A4 provides a realistic model of charged-lepton masses as well as a nearly degenerate neutrino mass matrix. Pheno...

Let 1M be a compact C’ differentiable manifold such that its rational homology is H3 (M; Q) zz Q if j E J U {0}, and Hj (M; Q) z (0) otherwise. Here J is a subset of the set of natural numbers N with cardinal 1, 2 or 3. A C1 map f : A4 + A4 is called transversal if for all m E N the graph of f m intersects transversally the diagonal of A4 x M at each point (2, z) such that z is a fixed point of...
