Static calibration of the RSRA active-isolator rotor balance system [PDF]
The Rotor Systems Research Aircraft (RSRA) active-isolator system is designed to reduce rotor vibrations transmitted to the airframe and to simultaneously measure all six forces and moments generated by the rotor.

Development of a rotating gravity gradiometer for earth orbit applications (AAFE) [PDF]
Some preliminary mission studies are described along with the design, fabrication, and test of a breadboard model of an earth orbital, rotating gravity gradiometer with a design goal of 10 to the minus 11th power/sec sq (0.01 EU) in a 35-sec integration ...

k‐Selective Electrical‐to‐Magnon Transduction with Finite‐Element‐Resolved Sub‐Micron Nanoantennas
Advanced Physics Research, EarlyView.We introduce a coupled finite‐element‐finite‐difference framework that links impedance‐matched nanoantenna geometries to propagating spin‐wave dynamics, capturing skin effects, proximity effects, and taper leakage beyond uniform‐current models. Applied to coplanar‐waveguide and stripline nanoantennas on yttrium‐iron‐garnet, the simulations achieve ...

The Anatomical Record, EarlyView.An elastic segment was found in the basal part of the whisker shaft in rats and mice. Application of force to the whisker bulb of isolated follicles caused bending and twisting of this segment. Active whisker movements deform this segment, causing whisker shaft deflection and selective activation of mechanoreceptors at different phases of whisking ...

The Anatomical Record, EarlyView.Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates
