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 ...

Vibrational study and spectra-structure correlations in magnesium disaccharinate heptahydrate, Mg(sac)₂⋅7H₂O

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

Relative Populations and IR Spectra of Cu38 Cluster at Finite Temperature Based on DFT and Statistical Thermodynamics Calculations

Frontiers in Chemistry, 2022
The relative populations of Cu38 isomers depend to a great extent on the temperature. Density functional theory and nanothermodynamics can be combined to compute the geometrical optimization of isomers and their spectroscopic properties in an approximate

Synthesis, crystal structure and properties of poly[(μ-2-methylpyridine N-oxide-κ2O:O)bis(μ-thiocyanato-κ2N:S)cobalt(II)]

Acta Crystallographica Section E: Crystallographic Communications
The title compound, [Co(NCS)2(C6H7NO)]n or Co(NCS)2(2-methylpyridine N-oxide), was prepared by the reaction of Co(NCS)2 and 2-methylpyridine N-oxide in methanol. All crystals obtained by this procedure show reticular pseudo-merohedric twinning, but after
