HPCL molecular imprinting SPE olaquindox
2014/10/11
A new and hydrophilic molecularly imprinted polymer (MIP) selective for olaquindox was prepared by bulk polymerisation using methacrylic acid as the functional monomer and ethylene glycol dimethacryla...
Phase Correlation based Local Illumination-invariant Method for Multi-Tempro Remote Sensing Image Matching
Phase Correlation Terrain Image Matching Illumination Angle Change
2014/9/9
This paper aims at image matching under significantly different illumination conditions, especially illumination angle changes, without prior knowledge of lighting conditions. We investigated the illu...
Non-reciprocal phase shift induced by an effective magnetic flux for light
Non-reciprocal phase shift induced effective magnetic
2015/8/6
Photons are neutral particles that do not interact directly with a magnetic field. However, recent theoretical work1,2 has shown that an effective magnetic field for photons can exist if t...
