Investigation on hard‐rock breaking performance and auxiliary mechanism of picks assisted with both‐sided high‐pressure water jets

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper investigates the high‐pressure water jet‐pick combined rock‐breaking mode (HPC), which employs high‐pressure water jets to precut grooves on both sides of the picks. The rock‐breaking patterns and performance of the HPC method are obtained, and the auxiliary rock‐breaking mechanism of water jet grooving is revealed.

A closer look at the uncertainty relation of position and momentum

open access: yes, 2010
We consider particles prepared by the von Neumann-L\"uders projection. For those particles the standard deviation of the momentum is discussed. We show that infinite standard deviations are not exceptions but rather typical.

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

open access: yesFlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

A Comparative Study of Ultrasonography and CT Venography in the Diagnosis of Budd‐Chiari Syndrome

open access: yesJournal of Clinical Ultrasound, EarlyView.
Budd‐Chiari syndrome (BCS) is characterized by hepatic venous outflow obstruction from the hepatic veins to the junction of the inferior vena cava (IVC) and right atrium. Ultrasound (US) and CT venography (CTV) are used as imaging techniques for the diagnosis of BCS, and We compared the diagnostic efficacy of the two modalities. The results showed that
