Droplet, EarlyView.A hand‐powered and mechanically programmable electrowetting‐on‐dielectric platform is demonstrated by integrating a contact‐separation triboelectric nanogenerator with a mechanically encoded punch‐card switch array. This unified mechanical–electrical architecture enables autonomous, portable, and robust droplet control for field‐deployable microfluidic

Similarities between line fishing and baited stereo-video estimations of length-frequency: Novel application of Kernel Density Estimates [PDF]
, 2012 Age structure data is essential for single species stock assessments but length-frequency data can provide complementary information. In south-western Australia, the majority of these data for exploited species are derived from line caught fish. However,
