This paper investigates the indistinguishable points (difficult to predict label) in semantic segmentation for large-scale 3D point clouds. The consist of those located complex boundary, with similar local textures but different categories, and isolate small hard areas, which largely harm performance segmentation. To address this challenge, we propose a novel Indistinguishable Area Focalization...

When normal metals (NMs) are attached to topological insulators or superconductors, it is conceivable that the quantum states in these finite adjacent materials can intermix. In this case---and because NM usually does not possess same symmetry as material---it pertinent ask whether zero-energy edge layer affected by presence of NM. To address issue, we consider three prototype systems simulated...

We investigate the hypothesis that within a combination of ‘number concept’ plus ‘substantive concept’, such as ‘eleven animals’, identity and indistinguishability present on level concepts, i.e., all eleven animals are identical indistinguishable, gives rise to statistical structure Bose–Einstein type similar how statistics is for indistinguishable quantum particles. proceed by identifying evi...
