Validation of the TruBlue Light Laser for Laryngeal Somatosensory and Perturbation Testing

The Laryngoscope, EarlyView.
This study validates a blue light laser method for assessing laryngeal somatosensory function by measuring perceptual thresholds, reflexive responses, discrimination acuity, and vocal perturbations in healthy adults. Results demonstrate that the method provides precise, reliable stimulation and yields quantifiable sensory and acoustic responses ...

Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission

Laser &Photonics Reviews, EarlyView.
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Joint Optimal Allocation of Resources for Multiple Jammer Based on Multi‐Agent Deep Reinforcement Learning

IET Radar, Sonar & Navigation
In response to the complex scenario where multiple jammers navigate through a netted radar system (NRS), this study presents an optimised allocation algorithm for cooperative jamming resources, namely the Multi‐Agent Jamming Resource Allocation (MJCJRA ...

On the Assembly of Actin Polymerization‐Powered Motors

Macromolecular Rapid Communications, EarlyView.
Actin polymerization‐powered motors have the highest speed when the actin recruiting‐polymerizing proteins are immobilized in polymer brushes on their surface. These motors orbit around larger tracer particles at pH above the isoelectric point of ActA but dock onto the tracer particles’ surface at lower pH. ABSTRACT Nano‐ and micromotors are a class of

A Stopped‐Flow Instrument for Millisecond Timescale Reaction Monitoring on a Standard NMR Spectrometer

Magnetic Resonance in Chemistry, EarlyView.
A new stopped‐flow instrument allows kinetic measurements of reactions 10 milliseconds after initiating them by mixing in a flow cell inserted into a standard NMR probe and spectrometer. High‐speed video, pressure and NMR line‐shape data are used to characterise mixing and stopping, and a protodeboronation reaction with a 5‐millisecond half‐life used ...

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...

Nonlinear Dynamics of a Passive Walker: Bifurcation and Stability Insights With Spring and Damper Mechanics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study explores the nonlinear dynamics associated with a passive dynamic walker (PDW), focusing on the bifurcation and stability insights derived from spring and damper mechanics. PDWs, which rely on gravity for stable locomotion without active control, exhibit a rich spectrum of behaviors, from periodic to chaotic motion.
