Cross Coupling Reaction

A general synthetic approach towards a class of water-soluble, high quantum yield fluorescent saccharide reporters using 6-morpholinonaphthalene-2-yl boronic acid as an illustrative case is reported. The strength and flexibility of this approach, which utilizes the Buchwald–Hartwig cross-coupling reaction, is further underscored by the preparation of several additional aminonaphthalenes in excellent yield, including one that bears a chiral unit.

Simulation Results

The incidental component in addition to the measured target signals is considered as noise of Positron Emission Tomography (PET) images. A novel method to denoise the PET images based on Empirical Mode Decomposition (EMD) and Independent Component Analysis (ICA) associated with Sparse Code Shrinkage (SCS) technique is proposed in this paper. EMD is executed to decompose a PET image into a number of Intrinsic Mode Functions (IMFs), which are used to reconstruct a new PET image after chosen by means of an inverse EMD procedure. By applying ICA to the new PET image, an orthogonal dataset can be obtained and the signal-noise separation can be realized. Then a clearer PET image can be reconstructed by SCS. The simulation results indicate that the proposed method is effective to denoise PET images.
