Optical Tweezers: A Comprehensive Tutorial from Calibration to Applications

A highly-focused laser beam can be used to trap microscopic particles. In this technique – known as optical tweezers – forces arise near the focal spot due to radiation pressure of the light beam (acting along the beam direction) and gradient forces which pull the particle towards the high-intensity focal spot.

A New Method for Imaging Seismic Quiescence and Its Application to the Mw = 8.3 Kurile Islands Earthquake on 15 November 2006

The seismic quiescence hypothesis asserts that the number of small earthquakes decreases in and around the focal area of a great earthquake near to its time of occurrence. Read more
