Research on Precise Identification of Rock Strength Based on Bolt Drilling Parameters
Energy Science &Engineering, EarlyView.Drilling detection test platform. ABSTRACT During roadway excavation, the presence of weak interlayers and fractured rock masses significantly affects roof stability. To achieve timely and effective roadway support, it is crucial to identify and predict different rock types based on drilling signals from roof bolters.

A tunable microwave absorption metamaterial inspired by moths evading bat detection
InfoMat, EarlyView.Electromagnetic radiation in the current environment has become complex and uncontrollable due to the advancement of wireless technology. Inspired by the moth surface cilia to bend and evade bat sonar detection, our work introduces a metamaterial incorporating broadband and tunable microwave absorption properties combined with deep learning algorithms.

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging
Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking
Laser &Photonics Reviews, EarlyView.Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.
