Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance
Droplet, EarlyView.Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology
Deep Underground Science and Engineering, EarlyView.This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Echo Particle Image Velocimetry [PDF]
Journal of Visualized Experiments, 2012 The transport of mass, momentum, and energy in fluid flows is ultimately determined by spatiotemporal distributions of the fluid velocity field.(1) Consequently, a prerequisite for understanding, predicting, and controlling fluid flows is the capability to measure the velocity field with adequate spatial and temporal resolution.(2) For velocity ...

Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT Reliable characterization of mineralogical and textural changes in rock samples is essential for understanding fluid–rock interactions, particularly in experimental studies simulating subsurface conditions. This study presents a reproducible protocol for scanning electron microscopy (SEM) analysis of rock surfaces before and after exposure to ...

Prenatal Diagnosis, EarlyView.ABSTRACT Objective To assess the efficacy of middle cerebral artery (MCA) Doppler ultrasonography in predicting neurological and respiratory outcomes in fetuses with fetal growth restriction (FGR) and to establish a correlation between MCA Doppler and head circumference (HC). Method Retrospective cohort study examining singleton pregnancies affected by

Pest Management Science, EarlyView.Optimizing PWM performance requires not only appropriate duty cycle selection, but also careful choice of adjuvant formulation tailored to each nozzle type. Drift control agents increased droplet size and reduced fine droplets, mitigating PWM‐induced variability. Decreasing the duty cycle consistently narrowed the spray angle.

Development and applications of two and three component particle image velocimetry techniques for simultaneous measurement in multi-phase flows and automative fuel sprays [PDF]
, 2010 The introduction of a new imaging approach for simultaneous multi-phase and multi-constituent velocity measurements is the main focus of this research. The proposed approach is based on the use of a single off-the-shelf colour camera which will enable ...
