Comparison of Pulse-Burst PIV Data to Simultaneous Conventional PIV Data
54th AIAA Aerospace Sciences Meeting, 2016 Time-resolved particle image velocimetry (PIV) using a pulse-burst laser has been acquired of a supersonic jet issuing into a Mach 0.8 crossflow. Simultaneously, the final pulse pair in each burst has been imaged using conventional PIV cameras to produce an independent two-component measurement and two stereoscopic measurements.

Nonequilibrium Period with Emergence of Marangoni Circulations in Meniscus Splitting
Advanced Materials Interfaces, Volume 13, Issue 5, 4 March 2026.The emergence and evolution of Marangoni convection in the meniscus splitting phenomenon are investigated. During the mass circulation of viscous fluids, the confluence and bifurcation of polymer dispersions beneath the evaporative interface lead to the inhomogeneous densification of the skin layer.

Aerospace Engineering Undergraduate Laboratory Courses: A Systematic Review (1990–2025)
Computer Applications in Engineering Education, Volume 34, Issue 2, March 2026.ABSTRACT This review examines the evolution of undergraduate aerospace engineering (AE) laboratories from 1990 to 2025, focusing on course formats, pedagogy, technology, and assessment. Once centered on traditional demonstration‐based exercises, AE laboratories have increasingly shifted toward hands‐on, project‐based, and hybrid physical‐virtual models

PIV-FlowDiffuser:Transfer-learning-based denoising diffusion models for PIV
Deep learning algorithms have significantly reduced the computational time and improved the spatial resolution of particle image velocimetry~(PIV). However, the models trained on synthetic datasets might have a degraded performance on practical particle images due to domain gaps.

CNS Neuroscience &Therapeutics, Volume 32, Issue 3, March 2026.This study identified a nonlinear, reverse L‐shaped relationship between the pan‐immune‐inflammation value (PIV) and all‐cause mortality (ACM) in critically ill acute ischemic stroke (AIS) patients, with a distinct threshold for risk stratification. Furthermore, the prognostic value of PIV was significantly stronger in patients without sepsis.
