Computations of power of re-randomization tests by exact methods are known to be computationally exhorbitant. We introduce a much cheaper "naive" method of evaluating power and show both by simulation and analytically for a special case that it very mildly overestimates true power. We further derive a normal approximation to re-randomization distributions of linear statistics and illustrate its...

The new triphasic potassium−substituted hydroxyapatite (KHAP), β−tricalcium phosphate (β−TCP), and calcium pyrophosphate (CPP) proportions using easy sol−gel method were synthesized. The prepared powders was characterized by X–ray diffraction (XRD), Fourier transform infrared (FTIR), Differential thermal behavior (DTA) analysis, Energy Dispersive X–ray Analysis (EDXA), and Brunauer–Emmett–Telle...

The merits of three indices based on weight (W) and height (H) were examined in the age group six to 15 years: W/H, W/H2, W/H3. The analysis was based ona survey of 1673 schoolchildren of both sexes from a rural housing block in Delhi. It showed that the index W/H2 was invariant with age in the range six to 15 years and that the other two indices were biased with respect to age. The index W/H2 ...

During mitosis, the entire content of the cell must be divided equally between two daughter cells before karyoand cytokinesis are completed. How is this complex process accomplished? In the case of the Golgi, it was found many years ago in tissue culture cells that the characteristic stack-like organization of the Golgi fragmented at the onset of mitosis (Robbins and Gonatas, 1964; Lucocq and W...

and Applied Analysis 3 Remark 5. Assumption (13) holds if the system has a unique solution. For brevity, we rewrite system (2)∼(5) in the vector form by introducing W(x, t) = (u(x, t), n(x, t)) and Y(x, t) = (a(x, t), b(x, t)). We denote by E 0 = H 2 ⋂H 1 0 (Ω) × H 1 0 (Ω) the space of vector functionsW(x, t) = (u(x, t), n(x, t)) with norm E0 = {‖u‖ 2 H 2 + ‖n‖ 2 H 1} 1/2 . (14) Similarly, we d...
