TL;DR: Test results and performance characterization of the first fixed-wing unmanned vehicle capable of full cross-domain operation in both the aerial and underwater environments with repeated transition and low-energy loitering capabilities are presented.

TL;DR: This paper looks to the natural world for solutions to many of the challenges associated with the design of fixed-wing cross-domain vehicles, inspired by multiple animals that cross between aerial and underwater domains, including the common murre.

TL;DR: In this article, a dynamic model of a draining structure is developed and verified experimentally on both a simple cylinder and a full wing structure, which can be incorporated into a full vehicle dynamic model to aid in the design, simulation, and control of hybrid UAVs with passively draining components.

TL;DR: Results indicate that the proposed centrifugal fluidic device is capable of a high capture success rate and high sample planarity, thus demonstrating the capabilities of the device to facilitate rapid histological evaluation of spheroids grown in standard 96-well plates.

TL;DR: In this article, an initially submerged aspect ratio 4 wing that translates through the water-air interface was investigated, and the results showed that the lift history is markedly different for low egress velocities versus high egress velocity, with low veloities exhibiting a large oscillation in lift coefficient and high velo cation exhibiting a more linear lift attenuation.
