Using infrared to improve face recognition of individuals with highly pigmented skin
iScience, 2023 Summary: Face recognition is widely used for security and access control. Its performance is limited when working with highly pigmented skin tones due to training bias caused by the under-representation of darker-skinned individuals in existing datasets ...

Finite volume effects in SU(2) with two adjoint fermions [PDF]
, 2011 Many evidences from lattice simulations support the idea that SU(2) with two Dirac flavors in the adjoint representation (also called Minimal Walking Technicolor) is IR conformal.

Macedonian Journal of Chemistry and Chemical Engineering, 2008 Infrared and Raman vibrational spectra of magnesium disaccharinate heptahydrate, Mg(sac)2⋅7H2O, in the 4000–380 cm–1 region (for infrared) and 4000–100 cm–1 region (for Raman) were studied. The assignment of the spectra was based on the experimental data

The Near-Infrared Broad Emission Line Region of Active Galactic Nuclei -- I. The Observations
, 2007 We present high quality (high signal-to-noise ratio and moderate spectral resolution) near-infrared (near-IR) spectroscopic observations of 23 well-known broad-emission line active galactic nuclei (AGN). Additionally, we obtained simultaneous (within two

An Empirically Based Calculation of the Extragalactic Infrared Background [PDF]
, 1997 Using the excellent observed correlations among various infrared wavebands with 12 and 60 micron luminosities, we calculate the 2-300 micron spectra of galaxies as a function of luminosity.

Ab Initio Simulation of the IR Spectrum of Hydrated Kaolinite
Crystals, 2021 The hydration of the basal surfaces of kaolinite is studied by theoretical methods. The cluster method was used to simulate the positions of atoms. The positions of the atoms of the basal surfaces of dry and hydrated minerals are optimized by minimizing ...
