Human mobility is a fundamental aspect of social behavior, with broad applications in transportation, urban planning, and epidemic modeling. However, for decades new mathematical formulas to model phenomena have been scarce usually discovered by analogy physical processes, such as the gravity radiation model. These sporadic discoveries are often thought rely on intuition luck fitting empirical data. Here, we propose systematic approach that leverages symbolic regression automatically...
Information security serves as the cornerstone for ensuring stable development of today’s highly digitized era. As cryptographic primitives with high and robust encryption capabilities, physical unclonable functions (PUFs) are recognized one critical solutions to address information leakage issues.
