Pilot evaluation of sailplane handling qualities [PDF]
The evaluation sailplanes were found generally deficient in the area of cockpit layout. The pilots indicated general dissatisfaction with high pitch sensitivity especially when coupled with inertially induced stick forces.

Advanced Science, EarlyView.This study uncovers two overlooked bottlenecks in cryogenic laser cooling of solids: symmetry‐driven fluorescence trapping and water vapor condensation. We demonstrate that breaking sample symmetry enhances fluorescence escape, while condensation dominates parasitic heating below 135 K.

Stalled and stall-free performance of axial-flow compressor stage with three inlet-guide-vane and stator-blade settings [PDF]
The performance of the first stage of a transonic, multistage compressor was mapped over a range of inlet-guide-vane and stator-blade settings. Both stall-free and deep-stall performance data were obtained.

Turbofan compressor dynamics during afterburner transients [PDF]
The effects of afterburner light-off and shut-down transients on compressor stability were investigated. Experimental results are based on detailed high-response pressure and temperature measurements on the Tf30-p-3 turbofan engine.

Advanced Science, EarlyView.Astrocytic TIA1‐mediated stress granules (SGs) promote demyelination by sequestering the mRNA of cholesterol synthesis genes. In this model, astrocytic TIA1‐mediated SGs were increased in the optic nerves of EAE mice, leading to the downregulation of cholesterol synthesis genes such as HMGCS1 through sequestration of their mRNA into SGs, which ...

Advanced Science, EarlyView.The formation of insulating Li2S during discharge in solid‐state lithium–sulfur batteries passivate reaction sites and limits sulfur utilization. In this work, a microstructure‐resolved modeling framework coupling transport and reaction kinetics is developed to predict charge–discharge behavior and reveal particle‐scale species evolution and incomplete

Observations of the Growth and Decay of Stall Cells during Stall and Surge in an Axial Compressor
International Journal of Rotating Machinery, 2017 This research investigated unsteady events such as stall inception, stall-cell development, and surge. Stall is characterized by a decrease in overall pressure rise and nonaxisymmetric throughflow.
