Particle Image Velocimetry (PIV) and optical flow methods represent two cornerstone approaches in experimental fluid dynamics and motion estimation. PIV employs tracer particles seeded in a fluid, ...

This article will review flow cytometry to help readers understand the challenges faced when increasing flow cytometer SNR (signal-to-noise ratio). Quick review: What is flow cytometry? Flow cytometry ...

Researchers have developed an optical system that accurately measures the flow of extraordinarily tiny amounts of liquids -- as small as 10 billionths of a liter (nanoliters) per minute. Researchers ...

Successful treatment of ischemic strokes, when blood supply to part of the brain has been blocked by a clot, involves restoring the blood flow as rapidly as possible, but imaging this resupply - ...
