However, pioneering work in the 1970s predicted that two-dimensional (2D) systems could host a unique topological phase transition known as the Berezinskii-Kosterlitz-Thouless (BKT) transition ...

However, pioneering work in the 1970s predicted that two-dimensional (2D) systems could host a unique topological phase transition known as the BKT transition, where vortex-antivortex pairs drive ...

Reducing injury rates thus relies on detecting and continually evaluating people with relatively large valgus motions. Objectives: To examine the potential of a two dimensional (2D) video analysis ...
