Through the interaction between thousands to millions of neurons, the cerebral cortex (outer layer of the brain) generates dynamic patterns of activity at many levels: From the scalp to mesoscopic ...

When a guitar string is plucked or a playground swing is set in motion, the movement gradually fades away. Physicists call these “damped harmonic oscillators,” and Newton’s laws do a fine job of ...

Mathematics Magazine presents articles and notes on undergraduate mathematical topics in a lively expository style that appeals to students and faculty throughout the undergraduate years. The journal ...

Dynamic nanomechanical testing has a number of well-known advantages, which include continuous stiffness and phase angle measurement having a broad range of applications in the testing of biomaterials ...
