Recombination of a surface-radical with a surface-olefin (SR-SOR) to form a six-membered ring is a critical step in the current mechanism for chemical vapor deposition growth of the diamond (100) surface. We estimate the rate constant for SR-SOR by combining quantum chemistry calculations, molecular mechanics calculations, and transition state theory. The ab initio calculations include extensiv...

OBJECTIVE We explored the relationships between sensory modulation and health-related quality of life (HRQOL), social supports, and mental health symptoms of anxiety and depression. METHOD Twenty-eight adult volunteers ages 18-60 participated in the study. Fourteen adults were sensory overresponsive (SOR), and 14 adults in a matched comparative group were not sensory overresponsive (NSOR). Al...

The successive overrelaxation (SOR) and the symmetric SOR (SSOR) iteration matrices are connected with the Jacobi iteration matrix in case these operators are associated with a (9, p 9)-generalized consistently ordered matrix through certain matrix identities. The validity of these identities has been proved in the last couple of years. Very recently an analogous matrix identity was shown to ho...

A new relaxation analysis and two acceleration schemes are proposed for the ve-point Red-Black Gauss-Seidel smoothing in multigrid for solving two dimensional Poisson equation. For a multigrid V cycle, we discovered that under-relaxation is applicable to restriction half cycle and overrelaxation is applicable to interpolation half cycle. Numerical experiments using modi ed multigrid V cycle alg...

Ahstract In this paper it is assumed that the point (or block) Jacobi manix. B associated with the matrix A is weakly 2-cyclic consistently ordered with complex, in general, eigen-value spectrum, a(B), lying in the interior of the infinite unit strip. It is then our objec~ live to apply and ex.tend the Young-Eidson algorithm in order to determine the real optimum relaxation factor in the follow...

Evidence-Based Answer Compared with usual care, case management does not reduce mortality in patients with multiple chronic diseases. (Strength of recommendation [SOR]: A, based on consistent, good-quality patient-oriented evidence.) Case management improves patient satisfaction with care for congestive heart failure and cancer, and increases patient perception of care coordination. It improves...

Abstract. Although the anthropogenic emissions of SO2 have decreased significantly in China, decrease SO42- PM2.5 is much smaller than that SO2. This implies an enhanced formation rate ambient air, and mechanism still under debate. work investigated particulate sulfate based on statistical analysis long-term observations Shijiazhuang Beijing supported with flow tube experiments.
