A piloted simulator study on augmentation systems to improve helicopter flying qualities in terrain flight [PDF]
Four basic single-rotor helicopters, one teetering, on articulated, and two hingeless, which were found to have a variety of major deficiencies in a previous fixed-based simulator study, were selected as baseline configurations. The stability and control

Hierarchical Summary Statistics Encoding Across Primary Visual and Posterior Parietal Cortices
Advanced Science, EarlyView.This study shows that mouse V1 simultaneously encodes the ensemble mean and variance of motion, providing a robust summary‐statistic representation that persists despite single‐neuron variability. These signals propagate to PPC, where they are transformed into abstract category representations during decision making.

IET Renewable Power Generation, 2012 This study aims to analyse different linear quadratic Gaussian (LQG) controllers' performances in terms of reducing the fatigue load of wind turbines' (WT) most costly components caused by the spatial turbulence of wind speed. Five LQGs with increasing control model complexity and a greater number of objectives are designed, the first four with ...

A summary of rotorcraft handling qualities research at NASA Ames Research Center [PDF]
, 1984 The objectives of the rotorcraft handling qualities research program at Ames Research Center are twofold: (1) to develop basic handling qualities design criteria to permit cost effective design decisions to be made for helicopters, and (2) to obtain ...

A Central Somatic Transmission Mediates Proprioceptive Facilitation of Muscle Pain
Advanced Science, EarlyView.Zhang et al. uncover a novel central mechanism for persistent muscle pain, in which TRPA1 sensitization in MeV proprioceptive neurons enhances somatic secretion. This, in turn, disinhibits descending pain control from neighboring noradrenergic locus coeruleus neurons via local GABAergic circuits, thereby promoting inflammatory muscle pain.
