Fine Structure of Zoll Spectra

Model-based quantification of EELS spectra: Including the fine structure.

An extension to model-based electron energy loss spectroscopy (EELS) quantification is reported to improve the possibility of modelling fine structure changes in electron energy loss spectra. An equalisation function is used in the energy loss near edge structure (ELNES) region to model the differences between a single atom differential cross section and the cross section for an atom in a cryst...

Soft Soil Seismic Design Spectra Including Soil-structure Interaction

Design spectrum is known as an essential tool in earthquake engineering for calculation of maximum (design) responses in a structural system. Soil-structure interaction (SSI), as a phenomenon of coupling of responses of a structure and its underlying soil, was explored after introduction of design spectra and has not been taken into account in developing a design spectrum traditionally. To cons...

Spectral Statistics on Zoll Surfaces

The subject of this article is a family of (partly conjectural) spectral invariants of a Laplace operator with a discrete spectrum 2j known as its k-level correlation functions Pk and level spacings distribution v. The 2-level (or pair) correlation function P2, for instance, measures the asymptotic number of spacings 2* 2* between normalized eigenvalues 2* as the eigenvalues tend to infinity. T...

Mid-infrared Atomic Fine-structure Emission Line Spectra of Luminous Infrared Galaxies: Spitzer/irs Spectra of the Goals Sample

We present the data and our analysis of mid-infrared atomic fine-structure emission lines detected in Spitzer/IRS high-resolution spectra of 202 local Luminous Infrared Galaxies (LIRGS) observed as part of the Great Observatories All-sky LIRG Survey (GOALS). We readily detect emission lines of [SIV], [NeII], [NeV], [NeIII], [SIII]18.7 μm, [OIV], [FeII], [SIII]33.5μm, and [SiII]. More than 75% o...
