Three-dimensional (3-D) light solitons in space–time, referred to as light bullets, have many novel properties and wide applications. Here we theoretically show how the combination of diffraction-free ...

Analyzing video footage of falls in older adults has emerged as an alternative to traditional lab studies. However, this approach is limited by the labor-intensive process of manually labeling body ...

Motion engineers can spend hours optimizing tuning parameters in servo-based systems, and still not get the performance they want. Their time may also be wasted if, at some point in the project, they ...

Ask any engineer what the velocity of a point on a rigid body is, and they will correctly say that it's the time rate of change of a linear position vector. Ask any engineer what angular velocity is, ...
