A rock physics model for predicting the velocities of isotropic sediments hosting heterogeneously distributed gas hydrates

Xiangyu Zhu, Weixin Pang, Anyu Li, Zhenyu Zhu et autres

SUMMARY Elastic rock physics models are widely used to estimate the saturation of hydrate in isotropic sediments. However, for isotropic media, the influence of heterogeneously distributed hydrate on the P- and S-wave velocities remains unclear, leading to uncertainties in hydrate saturation estimates. …

Structure and properties of piezoelectric aluminum nitride thin films deposited by radio-frequency magnetron sputtering for surface acoustic wave applications

Al-Ahsan Talukder, Nina Baule, Maximilian Steinhorst, Robert Rechenberg et autres

Aluminum nitride (AlN) is a promising piezoelectric material for surface acoustic wave (SAW) devices due to its high acoustic velocity and thermal stability. Achieving high-performance SAW devices requires highly c-axis-oriented, columnar AlN thin films with low surface roughness and high Young’s modulus. …

Efficacy of warm needling in patients with persistent allergic rhinitis: A multicenter randomized controlled trial

Wenbin Nie, Qi Hua Fan, Yijia Feng, Yuxiu Sun et autres

Objective Although there is evidence to support the therapeutic effect of acupuncture on allergic rhinitis (AR), it is not clear whether acupuncture can achieve an efficacy comparable to that of pharmacological therapy. This multicenter, non-inferiority, single-blinded randomized controlled trial aimed to compare …
