a matrix $pintextmd{c}^{ntimes n}$ is called a generalized reflection matrix if $p^{h}=p$ and $p^{2}=i$‎. ‎an $ntimes n$‎ ‎complex matrix $a$ is said to be a reflexive (anti-reflexive) matrix with respect to the generalized reflection matrix $p$ if $a=pap$ ($a=-pap$)‎. ‎in this paper‎, ‎we introduce two iterative methods for solving the pair of matrix equations $axb=c$ and $dxe=f$ over reflexiv...

matrix metalloproteinases (mmps) are a family of neutral proteinases that are important in normal development, cellular differentiation or migration, angiogenesis, neurogenesis, wound repair, and a wide range of pathological processes such as oxidative stress and neuroinflammation. mmps have been demonstrated to increase the permeability of the blood–brain barrier (bbb) by degrading the compone...

Drug release mechamsms of swellable systems for controlled drug administration were investigated The variations of the matrix relaxation and drug diffusion rates were quantified, by measuring the surface area exposed during matrix swelling and drug release as a function of impermeable coating coverage and location. Four different types of matrices, partially coated on various sides, were invest...

Abstract:transition and heat affected zones formed during surface remelting (in order to improve wear resistance) with TIGprocess has been investigated. Relationship between various TIG parameters and thickness of remelted and heataffected zones revealed that a high concentrated heat energy is imposed by TIG process which makes it a proper optionfor focused surface treatment. Based on microstru...

Skull reconstruction is an important and challenging task in craniofacial surgery planning, forensic investigation and anthropological studies. Our previous method called FAIS (Flip-Avoiding Interpolating Surface) [17] is reported to produce more accurate reconstruction of skulls compared to several existing methods. FAIS iteratively applies Laplacian deformation to non-rigidly register a refer...
