Identifying governing equations from observational data is crucial for understanding nonlinear physical systems but remains challenging due to the risk of overfitting. Here we introduce the Bi-Level ...

Rotating systems are widely used in various industries. Turbomachinery is employed to extract or perform work on fluids. These machines typically consist of rotating and stationary components, with ...

Frank Merle is used to confronting a messy world. He works on the mathematics of highly nonlinear systems—ones that respond in dramatic, unpredictable ways to even the smallest changes. It’s the same ...
