Long‐Term Efficacy of Immunotherapy in Autoimmune Autonomic Ganglionopathy—A 10‐Year Follow Up Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Autoimmune autonomic ganglionopathy (AAG) is a rare but potentially treatable cause of severe autonomic failure. Evidence guiding long‐term immunotherapy, treatment sequencing, and residual autonomic impairment is limited. We evaluated long‐term treatment response, residual autonomic dysfunction, and relapse patterns in patients with

Cold-atom shaping with MEMS scanning mirrors
Optics Letters, 2022 We demonstrate the integration of micro-electro-mechanical-systems (MEMS) scanning mirrors as active elements for the local optical pumping of ultra-cold atoms in a magneto-optical trap. A pair of MEMS mirrors steer a focused resonant beam through a cloud of trapped atoms shelved in the F

Photoacoustic imaging based on MEMS mirror scanning [PDF]
Biomedical Optics Express, 2010 A microelectromechanical systems (MEMS)-based photoacoustic imaging system is reported for the first time. In this system, the MEMS-based light scanning subsystem and a ring-shaped polyvinylidene fluoride (PVDF) transducer are integrated into a miniaturized probe that is capable of three-dimensional (3D) photoacoustic imaging.

Extend The Angular Displacement of A Thermal Actuated Scanning Mirror [PDF]
, 2012 [[abstract]]MEMS thermal actuators are known for their relatively high mechanical energy output for a given MEMS chip area, however, they are power consuming. This paper presents two novel actuating methods to achieve large scanning angular displacements
