Noise suppression with high Mach number inlets [PDF]
Experimental results were obtained for two types of high Mach number inlets, one with a translating centerbody and a fixed geometry inlet (collapsing cowl) with no centerbody. The aerodynamic and acoustic performance of these inlets was examined.

Photonic Systolic Array for All‐Optical Matrix–Matrix Multiplication
Laser &Photonics Reviews, EarlyView.A photonic systolic array is introduced, offering extreme parallelism in matrix‐matrix multiplication based on the synchronized movement of optical pulses along a crossbar array. Optical pulses traveling in perpendicular directions meet at freeform‐designed multiply‐accumulate units, each tailored to generate two signals whose intensity difference ...

Comparison of experimental and theoretical boundary-layer separation for inlets at incidence angle at low-speed conditions [PDF]
Comparisons between experimental and theoretical Mach number distributions and separation locations are presented for the internal surfaces of four different subsonic inlet geometries with exit diameters of 13.97 centimeters.

Flux Splitting for stiff equations: A notion on stability
, 2014 For low Mach number flows, there is a strong recent interest in the development and analysis of IMEX (implicit/explicit) schemes, which rely on a splitting of the convective flux into stiff and nonstiff parts.

Flight investigation of XB-70 structural response to oscillatory aerodynamic shaker excitation and correlation with analytical results [PDF]
The low frequency symmetric structural response and damping characteristics of the XB-70 airplane were measured at four flight conditions: heavyweight at a Mach number of 0.87 at an altitude of 7620 meters (25,000 feet); lightweight at a Mach number of 0.

A Rapid and Sensitive Method for the Determination of Chitosan Concentration by NMR Relaxometry
Magnetic Resonance in Chemistry, EarlyView.ABSTRACT A rapid, reagent‐free method for the quantification of chitosan in aqueous solutions was developed using 1H nuclear magnetic resonance (NMR) relaxometry. Transverse relaxation times (T2) of chitosan solutions (5–1000 mg/L) were measured with a Carr–Purcell–Meiboom–Gill (CPMG) sequence on a benchtop NMR relaxometer.
