Non-Fermi liquid (NFL) physics can be realized in quantum dot devices where competing interactions frustrate the exact screening of spin or charge degrees freedom. We show that a standard nanodevice architecture, involving coupled to both box and metallic leads, host an exotic SO(5) symmetry Kondo effect, with entangled spin. This NFL state is surprisingly robust breaking channel symmetry, but ...

This article proposes offline language-free writer identification based on speeded-up robust features (SURF), goes through training, enrollment, and identification stages. In all stages, an isotropic Box filter is first used to segment the handwritten text image into word regions (WRs). Then, the SURF descriptors (SUDs) of word region and the corresponding scales and orientations (SOs) are extr...
