Airborne spectral measurements of surface anisotropy during SCAR‐B [PDF]
Journal of Geophysical Research: Atmospheres, 1998 During the Smoke, Clouds, and Radiation‐Brazil (SCAR‐B) deployment, angular distributions of spectral reflectance for vegetated surfaces and smoke layers were measured using the scanning cloud absorption radiometer (CAR) mounted on the University of Washington C‐131A research aircraft.

Nflation: observable predictions from the random matrix mass spectrum [PDF]
, 2007 We carry out numerical investigations of the perturbations in Nflation models where the mass spectrum is generated by random matrix theory. The tensor-to-scalar ratio and non-gaussianity are already known to take the single-field values, and so the ...

Anisotropy of small-scale stratospheric irregularities retrieved from scintillations of a double star α-Cru observed by GOMOS/ENVISAT [PDF]
Atmospheric Measurement Techniques, 2012 In this paper, we discuss estimating anisotropy of air density irregularities (ratio of characteristic horizontal and vertical scales) from satellite observations of bi-chromatic scintillations of a double star whose components are not resolved by the ...

Non-perturbative determination of anisotropy coefficients and pressure gap at the deconfining transition of QCD [PDF]
, 1998 We propose a new non-perturbative method to compute derivatives of gauge coupling constants with respect to anisotropic lattice spacings (anisotropy coefficients).

Scattering and absorption properties of biomaterials for dental restorative applications [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 The physical understanding of the optical properties of dental biomaterials is mandatory for their final success in restorative applications. Light propagation in biological media is characterized by the absorption coefficient, the scattering coefficient,

Spectral anisotropies in high resolution three-dimensional simulations
Il Nuovo Cimento C, 2019 We present a 3D high resolution hybrid particle-in-cells simulation ofdecaying Alvénic turbulence and we compare its results with an analogoussimulations at MHD scales. We show that, while MHD simulations showspectral anisotropies in agreement with critical balance arguments, ation scale magnetic spectrum is more isotropic than predicted.

Exploring compensated isocurvature perturbations with CMB spectral distortion anisotropies [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 We develop a linear perturbation theory for the spectral $y$-distortions of the cosmic microwave background (CMB). The $y$-distortions generated during the recombination epoch are usually negligible because the energy transfer due to the Compton scattering is strongly suppressed at that time, but they can be significant if there is a considerable ...

AIP Advances, 2022 Bi-substituted rare-earth iron garnets, R3−xBixFe5O12 (Bi:RIG), where R represents one of the rare-earth elements, exhibit the excellent magneto-optical (MO) properties that increase with Bi content x. In addition, magnetic properties of Bi:RIGs, such as

Influence of Intermittency on the Energy Transfer Rate of Solar Wind Turbulence
The Astrophysical Journal Letters, 2023 The intermittency in the solar wind turbulence manifests itself in the anisotropic scaling due to the anisotropic spectral index and the intermittent level based on the extended P model. However, the influence of intermittency on the energy transfer rate

Functional Data Analysis of Multi-Angular Hyperspectral Data on Vegetation
Aceh International Journal of Science and Technology, 2012 The surface reflectance anisotropy can be estimated by directional reflectance analysis through the collection of multi-angular spectral data. Proper characterization of the surface anisotropy is animportant element in the successful interpretation of ...
