Spectral flow and resonance index [PDF]
Dissertationes Mathematicae, 2017 It has been shown recently that spectral flow admits a natural integer-valued extension to essential spectrum. This extension admits four different interpretations; two of them are singular spectral shift function and total resonance index. In this work we study resonance index outside essential spectrum.

Estimation of Soil Organic Matter Based on Spectral Indices Combined with Water Removal Algorithm
Remote SensingSoil moisture strongly interferes with the spectra of soil organic matter (SOM) in the near-infrared region, which reduces the correlation between organic matter and spectra and decreases accuracy in the prediction of SOM.

The Radio Spectral Index of 3C58 [PDF]
Symposium - International Astronomical Union, 2002 We report on 74 MHz and 330 MHz VLA observations of the plerionic supernova remnant 3C58. The radio spectral index, α, is uniform across the remnant to within 0.18, indicating a single source for the accelerated electrons. We find no emission from any shell surrounding the remnant.
