An Introduction to the Physics of Rapid Detection Tests
Rapid detection tests based on lateral flow assay (LFA), also called immunochromatographic tests, can be thought of as quite advanced, yet very robust, microlaboratories. (Part 1 of 2)
Analyzing Tsunami Waves with an Established Benchmark Model
The 1993 Hokkaidō earthquake in Japan caused tsunami waves that reached massive runup heights — one recorded wave in Monai Valley even reached as high as 32 m (~104 ft)!
Modeling the Behavior of an Oldroyd-B Polymer
Have you ever noticed that when a certain force is applied to a viscoelastic fluid, the fluid starts to look like beads on a string? Here, we showcase an example that uses an Oldroyd-B polymer.
