Grafting non-polar polymer chains on the surface of polar nanoparticles (e.g., silica) is an effective way to enhance particle/matrix interactions and thus promote their homogeneous dispersion within a matrix, which leads improved mechanical properties. Current grafting methods have not yet produced with well-defined polymers high density. Here, we employed anionic polymerization vacuum techniq...

The interphase properties in nanocomposites indicate the interaction between filler and matrix, which is dependent on preparation method, shape, size of chemical two phases. Local environment polymer matrix give rise to different dielectric compared that bulk material. These allow understanding their effects glass transition (Tg) nanocomposites. In this study, power law model was used predict b...

in this paper, at first we mention to some results related to pi and vertex co-pi indices and then we introduce the edge versions of co-pi indices. then, we obtain some properties about these new indices.

The ATP-Mg/Pi carrier in liver mitochondria is activated by micromolar Ca2+ and mediates net adenine nucleotide transport into and out of the mitochondrial matrix. The purpose of this study was to characterize certain features of ATP-Mg/Pi carrier activity that are essential for understanding how the mitochondrial adenine nucleotide content is regulated. The relative importance of ATP and ADP a...

In this work, we perform a spectral analysis of flipped multilevel Toeplitz sequences, i.e., study the asymptotic behavior $\{Y_{{n}} T_{{n}} (f)\}_{{n}}$, where $T_{{n}}(f)$ is real, square matrix generated by function $f\in L^1([-\pi,\pi]^d)$ and $Y_n$ exchange matrix, which has 1's on main antidiagonal. line with what have shown for unilevel spectrum determined 2 x matrix-valued whose eigenv...

During ischemia in so-called slow heart-rate hearts, there is a marked inhibition of the mitochondrial ATPase mediated by inhibitor protein binding to the enzyme (Rouslin, W., and Pullman, M. E. (1987) J. Mol. Cell. Cardiol. 19, 661-668). This ischemia-induced ATPase inhibition is triggered by a drop in mitochondrial matrix pH (Rouslin, W. (1987) J. Biol. Chem. 262, 3472-3476) which occurs as a...

In this paper, an iterative method is constructed to solve the following constrained linear matrix equations system: [A1(X), A2(X), ∙ ∙ ∙ , Ar (X)] = [E1, E2, ∙ ∙ ∙ , Er ], X ∈ S = {X |X = U (X)}, where Ai is a linear operator from Cm×n onto C pi ×qi , Ei ∈ C pi ×qi , i = 1, 2, ∙ ∙ ∙ , r , and U is a linear self-conjugate involution operator. When the above constrained matrix equations system i...

This article proposes a cascade proportional-integral second-order sliding mode control (PI-SMC) method for matrix converter-fed brushless doubly fed induction machine (BDFIM). The PI-SMC consists of PI speed controller with an inner-loop (SMC). provides reference to the SMC constraints according system requirements in terms maximum current and speed. As discontinuous sign function traditional ...

The ground and low-lying excited states of the pyrimidine nucleo bases uracil, thymine, and 1-methylthymine have been characterized using ab initio coupled-cluster with approximate doubles (CC2) and a combination of density functional theory (DFT) and semiempirical multireference configuration interaction (MRCI) methods. Intersystem crossing rate constants have been determined perturbationally ...
