TL;DR: A plant warming system includes a sensor configured to acquire temperature data representative of a temperature of a plant, a heating system including an antenna configured to direct microwaves toward the plant, and a control system configured to control operation of the heating system based on the temperature data as mentioned in this paper.

TL;DR: In this paper, a digital imaging device is configured to capture images of a region of a contact between a wheel of a terrestrial vehicle and a surface ("contact region") and a correlator is configurable to correlate a first digital image of the contact region captured at first time with a second digital image captured at a second time.

Surface plasmon coupling between two nano Au particles
TL;DR: In this article, the authors present experimental and computer simulation studies on the plasmon resonance of single nano Au particles and nano Au particle pairs in close proximity and show that the resonant wavelength peak of two particle plasmons is red-shifted in comparison to that of a single particle and the shift decays approximately exponentially with particle spacing, and drops to zero when the gap between two particles exceeds about 2.5 times the particle short axis length.
