Introduction Criteria for mild cognitive impairment (MCI) used in many clinical trials are susceptible to "false-positive (FP)" errors that can be avoided by an actuarial psychometric approach. Methods Cluster analysis was applied to baseline neuropsychological test data from 756 MCI participants in the Alzheimer's Disease Cooperative Study donepezil trial. Treatment groups were compared afte...

We describe a new Newton-type algorithm for the solution of inequality constrained minimization problems. The algorithm is based on an active-set strategy and, at each iteration, only requires the solution of one linear system. Under mild assumptions, and without requiring strict complementarity, we prove q-quadratic convergence of the primal variables towards the solution.

On the existence for solutions of evolutionary equations, there are many works and methods 1–7 . For example, the fixed principle 1, 3–5, 7 and Galerkin approximations 2, 6 . They are very classical methods to prove existence and uniqueness. Generally speaking, there are four solution concepts. That is, weak solution, mild solution, strong solution, and classical solution. We can obtain differe...

Nanostructured Mn oxide clusters supported on mesoporous silica KIT-6 efficiently evolve O(2) in aqueous solution under mild conditions.

semilinear stochastic evolution equations with multiplicative l'evy noise are considered‎. ‎the drift term is assumed to be monotone nonlinear and with linear growth‎. ‎unlike other similar works‎, ‎we do not impose coercivity conditions on coefficients‎. ‎we establish the continuous dependence of the mild solution with respect to initial conditions and also on coefficients. ‎as corollarie...

hydrogen peroxide is an important mild oxidant which is widely used in various applications including remediation of waste waters and drinking water resources. the safe level of h2o2 residue has to be controlled through accurate and precise measurement methods. a facile spectrophotometric method for the determination of hydrogen peroxide is based on the reaction of iodine solution with toluidin...

In this article, the effect of potassium on structure and anticorrosion properties of zinc phosphate pigments has been investigated. The co-precipitation method was selected as synthesis method of potassium zinc phosphate pigment. Then the synthesized pigment was characterized by x-ray diffraction XRD, Fourier transform infrared FTIR and Raman spectroscopy. Morphology of the powders was investi...

Mild-mannered catalyst: a novel procedure to load a MoS(2) co-catalyst onto the surface of silicon under mild-conditions (room temperature, atmospheric pressure, aqueous solution) by a photo-assisted electrodeposition process employing commercially available precursors is reported. The obtained Si-NW@MoS(2) photocathode showed similar catalytic activity for light-driven H(2) generation compared...
