DOI: 10.1007/s00397-017-1047-7
Abstract: We present a new method for performing passive probe microrheology. Using a simple theoretical framework, we show how probes’ mean-squared displacements can be extracted by analyzing intensity fluctuations in optical microscopy videos via differential dynamic… read more here.

DOI: 10.1109/access.2022.3217239
Abstract: The motion of many robotics systems, such as the rotation of unmanned aerial vehicles, can be modeled by SO(3). However, the difficulties in the parameterization of the SO(3) makes it hard to implement the state-of-the-art… read more here.

DOI: 10.1109/lra.2021.3062338
Abstract: Most mobile robots follow a modular sense-plan-act system architecture that can lead to poor performance or even catastrophic failure for visual inertial navigation systems due to trajectories devoid of feature matches. Planning in belief space… read more here.
