Let G be a linear algebraic group acting linearly on vector space (or more generally, an affine variety) V, and let k[V]G the corresponding algebra of invariant polynomial functions. A separating set S⊆k[V]G is polynomials with property that for all v,w∈V, if there exists f∈k[V]G $v$ $w$, then f∈S $w$. In this article, we consider action G=GL2(C) C-vector M2n n-tuples 2×2 matrices by simultane...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
Background: Meningioma is one of the most common tumors of the central nervous system. It was shown that meningioma had up-regulated expression of Matrix Metalloproteinases (MMPs) that involved in cell growth, angiogenesis and metastasis. Objectives: The aim of the study was the assessment of serum MMP-2 and -9 levels in patients with different grades of meningioma. Materials & Me...
Unitary operations are a specific class of linear transformations that have become an essential ingredient for the realization classical and quantum information processing. The ability implementing any n-dimensional unitary signal transformation by using reconfigurable optical hardware has recently led to pioneering concept programmable processor, whose basic building block (BB) must be correct...
