2010/4/12
I propose a quantum imaging method that can beat the Rayleigh-Abbe diffraction limit and achieve de Broglie resolution without requiring a multiphoton absorber as the detector. Using the same non-clas...
Optimum Condition of High Pressure Treatment for the Preparation of Lysozyme-Dextran Complex Found by Random-Centroid Optimization
