We show how to construct low energy solutions to the Randall-Sundrum II (RSII) model by using an associated five-dimensional anti-de Sitter space (AdS(5)) and/or four-dimensional conformal field theory (CFT(4)) problem. The RSII solution is given as a perturbation of the AdS(5)-CFT(4) solution, with the perturbation parameter being the radius of curvature of the brane metric compared to the AdS length ?. The brane metric is then a specific perturbation of the AdS(5)-CFT(4) boundary metric. For low curvatures the RSII solution reproduces 4D general relativity on the brane. Recently, AdS(5)-CFT(4) solutions with a 4D Schwarzschild boundary metric were numerically constructed. We modify the boundary conditions to numerically construct large RSII static black holes with radius up to ~20?. For a large radius, the RSII solutions are indeed close to the associated AdS(5)-CFT(4) solution. 相似文献

Data processing for three dimensional mass spectrometry (3D-MS) imaging was investigated, starting with a consideration of
the challenges in its practical implementation using a series of sections of a tissue volume. The technical issues related
to data reduction, 2D imaging data alignment, 3D visualization, and statistical data analysis were identified. Software solutions
for these tasks were developed using functions in MATLAB. Peak detection and peak alignment were applied to reduce the data
size, while retaining the mass accuracy. The main morphologic features of tissue sections were extracted using a classification
method for data alignment. Data insertion was performed to construct a 3D data set with spectral information that can be used
for generating 3D views and for data analysis. The imaging data previously obtained for a mouse brain using desorption electrospray
ionization mass spectrometry (DESI-MS) imaging have been used to test and demonstrate the new methodology. 相似文献
