Spontaneous Layer-Pseudospin Domain Walls in Bilayer Graphene
Bilayer graphene is susceptible to a family of unusual broken symmetry states
with spin and valley dependent layer polarization. We report on a microscopic
study of the domain walls in these systems, demonstrating that they have
interesting microscopic structures related to order-induced topological
characters. We use our results to estimate Ginzburg-Landau model parameters and
transition temperatures for the ordered states of bilayer graphene.Comment: 4 pages, 3 figure
Real-time motion data annotation via action string
Even though there is an explosive growth of motion capture data, there is still a lack of efficient and reliable methods to automatically annotate all the motions in a database. Moreover, because of the popularity of mocap devices in home entertainment systems, real-time human motion annotation or recognition becomes more and more imperative. This paper presents a new motion annotation method that achieves both the aforementioned two targets at the same time. It uses a probabilistic pose feature based on the Gaussian Mixture Model to represent each pose. After training a clustered pose feature model, a motion clip could be represented as an action string. Then, a dynamic programming-based string matching method is introduced to compare the differences between action strings. Finally, in order to achieve the real-time target, we construct a hierarchical action string structure to quickly label each given action string. The experimental results demonstrate the efficacy and efficiency of our method
