A 2014 paper on a robotic system for patients who have had a stroke contains three pages of equations that are not original.
According to the retraction note, “Cascade controller design and stability analysis in FES-aided upper arm stroke rehabilitation robotic system” copied the equations from a paper that other researchers presented at a conference in 2012. The papers both describe a system that delivers a boost of electricity to stroke patients’ arms to help them perform a task.
Here’s the note, from Nonlinear Dynamics:

To climate scientist Pieter Tans, a “novel” air sampling device in a recent paper looked a little too familiar. Specifically, like a device that he had invented —
