We develop the theory of agrarian invariants, which are algebraic counterparts to $L^2$-invariants. Specifically, we introduce notions Betti numbers, acyclicity, torsion and polytope for finite free $G$-CW-co

background: leukemia is a malignant proliferative disorder of the hematopoietic cells. the important role of angiogenesis in leukemia has been reported by several studies. matrix metalloproteinases (mmps) are a large group of endopeptidases which degredate the extracellular matrix and play an important role in angiogenesis. objective: the present study was conducted to evaluate the patterns of ...
