Scaling of Spectral Anisotropy in Two-Dimensional Electron Magneto-Hydrodynamic Turbulence

Journal of the Physical Society of Japan, 2001
It is demonstrated using numerical simulation that spectral anisotropy in two-dimensional decaying electron magneto-hydrodynamic turbulence varies linearly with the ratio of fluctuating to mean magnetic field. Turbulent excitation scales larger ( k λ e 1) than the electron skin depth scale length (λ e ) are shown to exhibit such linear scaling ...

Quantitative Anisotropy Imaging based on Spectral Interferometry

2020
Optical imaging is unique for its ability to use light to provide both structural and functional information from microscopic to macroscopic scales. As for microscopy, how to create contrast for better visualization of detected objects is one of the most important topic.

Angular anisotropy of 2H NMR spectral densities in phospholipid bilayers containing cholesterol

Chemical Physics Letters, 1992
Abstract Spin—lattice (R1Z) and quadrupolar order (R1Q) relaxation rates were measured for bilayers of macroscopically oriented 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC-d54) containing cholesterol (1:1 molar ratio), using inversion recovery and broadband Jeener—Broekaert pulse sequences, respectively.

Spectral-domain modeling of anisotropy in ferrite microwave circuits with multilayer configuration

2009 3rd International Conference on Signals, Circuits and Systems (SCS), 2009
This paper deals with the analysis of anisotropy effects on the dispersion parameters of multilayer microwave circuits with ferrite substrates. Since ferrites present a biaxial anisotropy, spectral analysis of multilayered configurations with such substrates is not generalized yet but restricted to some particular cases of tensors. The proposed general

[Spectral anisotropy of chloroplasts, subchloroplast particles and pigment-protein complexes].

Biofizika, 1981
Anisotropic properties of pea chloroplasts, subchloroplast fragments (photosystem 1 particles and pigment-protein complexes) and the blue-green algae oriented in polyacrylamide gel were investigated. It was shown that linear dichroism spectra of chloroplasts are the superposition of the corresponding spectra for the main light harvesting complex (HMLC)

Combining geometric-optical and spectral invariants theories for modeling canopy fluorescence anisotropy

The spectral invariants theory (p-theory) has received much attention in the field of quantitative remote sensing over the past few decades and has been adopted for modeling of canopy solar-induced chlorophyll fluorescence (SIF). However, the spectral invariant properties (SIP) in simple analytical formulas have not been applied for modeling canopy ...
