The dialogue between History and Political Science (PC), whose theoretical concepts are very useful for the interpretation of longer conjunctural units, needs to be sharpened. In this paper, following possibility studying 1890-1930 as a unitary block, we will try demonstrate usefulness PC historiography period "Crisis Liberalism" advancement study political parties. We cut out first course cris...

In this paper, we focus on the structured multi-frame vectors in Hilbert $C^*$-modules. More precisely, it will be shown that the set of all complete multi-frame vectors for a unitary system can be parameterized by the set of all surjective operators, in the local commutant. Similar results hold for the set of all complete wandering vectors and complete multi-Riesz vectors, when the surjective ...

In 1955, H. Dye defined certain projections of a C∗-matrix algebra by Pi,j(a) = (1 + aa ∗)−1 ⊗ Ei,i + (1 + aa∗)−1a⊗ Ei,j + a∗(1 + aa∗)−1 ⊗ Ej,i + a∗(1 + aa∗)−1a⊗ Ej,j , which was used to show that in the case of factors not of type I2n, the unitary group determines the algebraic type of that factor. We study these projections and we show that in M2(C), the set of such projections includes all t...

We distinguish two notions of substitutes for discrete inputs of a firm. Class substitutes are defined assuming that units of a given input have the same price while unitary substitutes treat each unit as a distinct input with its own price. Unitary substitutes is necessary and sufficient for such results as the robust existence of equilibrium, the robust inclusion of the Vickrey outcome in the...

background and objective: vesicoureteral reflux (vur) is one of the most common urinary tract abnormalities in patients with urinary tract infection. nowadays noninvasive diagnostic methods are suggested to recognize vur and its severity. methods: we measured urinary and serum fibronectin in 51 children with vur. results: the mean serum fibronectin was 318.3±112.1 in children with low grade vur...

A shared-bus system consists of multiple buses shared by multiple functional units. Two important problems involved in the high-level synthesis of such a system are: the scheduling problem and the resource allocation problem for a given data-flow graph (DFG). This paper proposes methods to optimally solve these two problems. The proposed methods are applicable to both non-iterative DFGs and ite...

We introduce a simple uniform structure of elementary Φ-unitary matrices. Elementary Φ-unitary transformations are the extentions of Householder transformations in real and complex spaces with a definite or an indefinite inner product induced by a nonsingular signature matrix Φ. The extentions are found useful in the computations of complex matrices or special structured matrices. For two (comp...
