Infra-Red Plasmonic Sensors [PDF]

open access: yesChemosensors, 2018
Plasmonic sensors exploiting the localized surface plasmon resonance (LSPR) of noble metal nanoparticles are common in the visual spectrum. However, bio-sensors near the infra-red (NIR) windows (600–900 nm and 1000–1400 nm) are of interest, as in these ...

The Use of Thermal Infra-Red Imagery to Elucidate the Dynamics and Processes Occurring in Fog

open access: yesAtmosphere, 2020
Improving our ability to predict fog accurately is currently a high priority for Numerical Weather Prediction models. Such an endeavour requires numerous types of observations of real fog as a means to both better understand it and also provide an ...

New infra-red enhancements in 4-derivative gravity [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
4-Derivative gravity provides a renormalizable theory of quantum gravity at the price of introducing a physical ghost, which could admit a sensible positive-energy quantization.

Multichannel Classifier for Recognizing Acoustic Impacts Recorded with a phi-OTDR

open access: yesSensors, 2023
The purpose of this work is to increase the security of the perimeter of an area from unauthorized intrusions by creating an improved algorithm for classifying acoustic impacts recorded with a sensor system based on a phase-sensitive optical time ...

Orthorectification of Helicopter-Borne High Resolution Experimental Burn Observation from Infra Red Handheld Imagers

open access: yesRemote Sensing, 2021
To pursue the development and validation of coupled fire-atmosphere models, the wildland fire modeling community needs validation data sets with scenarios where fire-induced winds influence fire front behavior, and with high temporal and spatial ...

Infra-red soft universality [PDF]

open access: yesPhysics Letters B, 1995
We show that in a special class of theories the commonly assumed universal form of the soft supersymmetry--breaking terms is approached in the infra--red limit. The resulting universal scalar mass and trilinear coupling are predicted in terms of the gaugino mass.

Multicolour single molecule imaging in cells with near infra-red dyes.

open access: yesPLoS ONE, 2012
BackgroundThe autofluorescence background of biological samples impedes the detection of single molecules when imaging. The most common method of reducing the background is to use evanescent field excitation, which is incompatible with imaging beyond the
