Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs

Droplet, EarlyView.
Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...

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 ...

Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...

Transcending the Space‐Bandwidth and Lighting Trade‐Offs: A Programmable Self‐Mixing Interferometry Imager for Cross‐Scale Surface Inspection

Laser &Photonics Reviews, EarlyView.
This work reports a laser diode‐based self‐mixing interferometry imager featuring illumination‐invariance imaging, a 500 kHz pixel rate, and an 8.77 µm lateral resolution. It also features a programmable field‐of‐view and leading space‐bandwidth product that surpasses existing technologies by an order of magnitude, enabling cross‐scale workflow ...

Estimation of myocardial deformation using correlation image velocimetry

BMC Medical Imaging, 2017
Background Tagged Magnetic Resonance (tMR) imaging is a powerful technique for determining cardiovascular abnormalities. One of the reasons for tMR not being used in routine clinical practice is the lack of easy-to-use tools for image analysis and strain
