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 ...

Flavours and infra-red instability in holography

open access: yesJournal of High Energy Physics, 2017
With a simple gravitational model in five dimensions, defined by Einstein-gravity with a negative cosmological constant, coupled to a Dirac-Born-Infeld and a Chern-Simons term, we explore the fate of BF-bound violation for a probe scalar field and a ...

Determination of the adsorption isotherms and transport diffusivities of gases in mixtures inside zeolitic crystals using Infra-Red Micro-imaging [PDF]

open access: yesMethodsX, 2020
Different regions of Infra-Red (IR) light absorption by guest molecules inside a zeolitic crystal are measured and quantified to determine binary adsorption isotherms and transport diffusivities.

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 ...

Classification of Acoustic Influences Registered with Phase-Sensitive OTDR Using Pattern Recognition Methods

open access: yesSensors, 2023
This article is devoted to the development of a classification method based on an artificial neural network architecture to solve the problem of recognizing the sources of acoustic influences recorded by a phase-sensitive OTDR.

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 ...

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.

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 ...

On the Physical Significance of Infra-red Corrections to Inflationary Observables [PDF]

open access: yes, 2007
Inflationary observables, like the power spectrum, computed at one- and higher-order loop level seem to be plagued by large infra-red corrections. In this short note, we point out that these large infra-red corrections appear only in quantities which are
