ABSTRACT The Laurentide Ice Sheet covered vast areas of North America during the Wisconsinan, including the Labrador Shelf, off the coast of eastern Canada. The shelf is characterized by glacial cross‐shelf troughs, which have been considered as predominantly eroded by the last ice advance.

Controlling the Center of Mass Motion of Levitated Particles Using Structured Wavefronts
Optically levitated particles have great potential for quantum‐enhanced sensing. Precise control of the trapping beam is crucial to improve the stability and confinement of these systems. Here, we study how structured wavefronts can be used to control the center‐of‐mass motion of levitated particles, enhancing trap stiffness and enabling stable ...

A Novel Non‐Torque Dynamic Load Decoupling Method for Large Wind Turbine Nacelle Test Bench
ABSTRACT Accurate reproduction of non‐torque dynamic loads is a key challenge for full‐scale wind turbine nacelle test benches, where the nacelle‐level drivetrain is validated under controlled multi‐degree‐of‐freedom mechanical loading. This study focuses on the shaft‐conjugate load application unit (LAU) adopted in the 25‐MW‐class full‐scale wind ...

ABSTRACT To reduce the need for scheduled wind turbine blade inspections and large‐scale repairs, a novel distributed acoustic sensing system for monitoring the structural health of wind turbine blades is proposed. This integral passive monitoring system utilizes a sparse array of in‐blade multimodal sensors and a single blade‐external downtower sensor,

Mesoscale Modeling of Titan’s Shangri‐La Region: The Impact of Surface Properties on Winds
Abstract The knowledge of Titan’s near‐surface atmosphere is sparse. The Huygens descent probe measured winds, and the multiple dune field observations and possible dust storms suggest active near‐surface dynamics. The Dragonfly rotorcraft lander will fly close to the surface in the Shangri‐La region, near the Huygens landing site, where complex dune ...
