Instabilities of a family of oblate stellar spheroids [PDF]
We have examined the stability of a sequence of oblate elliptical galaxy models having the Stackel form suggested by Kuz'min & Kutuzov. We have employed the 2-integral DFs given by Dejonghe & de Zeeuw for which flattened non-rotating models are characterized by counter-streaming motion and are radially cool; we introduce net rotation in some ...

Reynolds stress anisotropy is estimated from the stress spheroids, based on 20 Hz ultrasonic anemometer measurements, performed in the coastal area of northern France, over a 1.5-year long period.

The orbits about an oblate spheroid [PDF]
Verf. diskutiert die hauptsächliche Perihelstörung eines Aufpunktes, der sich (in nicht allzu kleiner Entfernung) im Newtonschen Gravitationsfeld eines abgeplatteten inhomogenen Spheroids bewegt. Da das Feld nicht radialsymmetrisch ist, so hängt die Störung auch von der jeweiligen Bahnneigung ab.

CSAKD: Determining Absolute Ligand Affinities From 19F NMR Chemical Shift Anisotropy
Affinity determination is crucial in drug discovery, yet remains difficult for weakly binding fragments. We introduce chemical shift anisotropy KD$K_{\text{D}}$ (CSAKD) by 19F$^{19}{\rm F}$ NMR relaxation experiments, a titration‐free method that requires no isotopic labeling.

Controlling the magnetic anisotropy of nanoparticles is a crucial but challenging step for developing new magnetic functions. Here, we demonstrate a simple approach to controlling the shape of Co nanoparticles in a Co-SiO2 nanogranular film from oblate ...

An Efficient Computational Technique for the Electromagnetic Scattering by Prolate Spheroids
In this paper we present an efficient Matlab computation of a 3-D electromagnetic scattering problem, in which a plane wave impinges with a generic inclination onto a conducting ellipsoid of revolution.

Geometric Nonuniformity Localizes Valence Orbitals in Gold Clusters: Case Study on [Au23(SC6H11)16]–
The electronic structure of [Au23(SC6H11)16]–, a monolayer‐protected gold cluster with a nonuniform Au13 core, was investigated. Anion photoelectron spectroscopy and density functional theory calculations revealed that the highest occupied molecular orbital (HOMO) and HOMO‐1 are localized on the two triangular Au3 units at the ends of the Au13 core ...

AXISYMMETRIC DYNAMIC BEHAVIOUR OF THIN OBLATE SHELLS
This paper presents a theoretical investigation of the axisymmetric free vibrations of an isotropic thin oblate spheroid shell. The analysis depends on the Rayliegh – Ritz's method. The non – shallow shell theory is used for the analysis.

Theoretical bases of the geometrical identification of a common inter-radar space [PDF]
A condition for the successful inter-radar comparison between two radars is the timespace synchronization in the middle region where the comparison is the most effective.
