Accurate Robust Symmetry Estimation Stephen Smith and Mark Jenkinson There are various applications, both in medical and non-medical image analysis, which require the automatic detection of the line (2D images) or plane (3D) of reflective symmetry o
Intensity and Edge-Based Symmetry Detection Applied to Car-Following We present two methods for detecting symmetry in images, one based directly on the intensity values and another one based on a discrete representation of local orientation. A symme
The ratchet motion of a Brownian particle in a symmetric periodic potential under a rocking force that breaks the temporal symmetry is studied. As long as the relaxation time in the thermal background is much shorter than the forcing period, the uni

In the course of studying physics I became, like any student of physics, familiar with many fundamental equations and their solu- tions, but I wasn’t really able to see their connection. I was thrilled when I understood that most of them have a com-
Femtosecond laser filamentation is generally initialized from unpredictable symmetry breaking caused by random noise, causing it to be barely controlled. However, it is always anticipated for stable and controllable filamentation. We present and demo
The active control of electromagnetic response in metamaterial and mutual coupling between resonant building blocks is of fundamental importance in realizing high-quality metamaterials. In this work, we propose and experimentally demonstrate the tuna
Over the past decade, parity-time (PT)-symmetric Hamiltonians have been experimentally realized in classical, optical settings with balanced gain and loss, or in quantum systems with localized loss. In both realizations, the PT-symmetry-breaking tran
