Second COVID-19 Wave in Europe Less Lethal Than First Wave

sarah JonasResearch Results

As Europe experienced its enormous second wave of the COVID-19 disease, researchers noticed the mortality rate was much lower than during the first wave. This inspired some to study and quantify the mortality rate on a country-by-country basis to determine how much the rate decreased. In Chaos, they introduce methods to study the progression of COVID-19 cases to deaths during the pandemic’s different waves; their methods involve applied mathematics, specifically nonlinear dynamics, and time series analysis.

‘Chaotic’ Way to Create Insectlike Gaits for Robots

sarah JonasResearch Results

Researchers in Japan and Italy are embracing chaos and nonlinear physics to create insectlike gaits for tiny robots — complete with a locomotion controller to provide a brain-machine interface. Biology and physics are permeated by universal phenomena fundamentally grounded in nonlinear physics, and it inspired the researchers’ work. In the journal Chaos, the group describes using a system of three nonlinear differential equations as a building block for central pattern generators to control the gait of a robotic insect.
