Surface effects on the dual-mode vibration of [110] silver nanowires with different cross-sections [PDF]
, 2012 Dual-mode vibration of nanowires has been reported experimentally through actuation of the nanowire at its resonance frequency, which is expected to open up a variety of new modalities for the NEMS that could operate in the nonlinear regime.

Dual-mode adaptive-SVD ghost imaging
Optics Express, 2023 In this paper, we present a dual-mode adaptive singular value decomposition ghost imaging (A-SVD GI), which can be easily switched between the modes of imaging and edge detection. It can adaptively localize the foreground pixels via a threshold selection method.
