Application of Ion Cyclotron Resonance to the Study of Inelastic Excitation by Low-Energy Electrons [PDF]

open access: yes, 1969
The geometry of the resonance cell employed for ion cyclotron resonance spectroscopy (1-3) is ideally suited for studying inelastic excitation by low-energy electrons.

The Agulhas Ridge, South Atlantic: the peculiar structure of a fracture zone [PDF]

open access: yes, 2005
The Agulhas Ridge is a prominent topographic feature that parallels the Agulhas-Falkland Fracture Zone (AFFZ). Seismic reflection and wide angle/refraction data have led to the classification of this feature as a transverse ridge.

Fundamentality of Ridge Functions

open access: yesJournal of Approximation Theory, 1993
For \(d,n\in \mathbb{N}\) denote by \(\Omega\) the set of all real \(d\times n\) matrices and let \(M(\Omega)= \text{span} (g(A.x)\): \(A\in\Omega\), \(g\in C(\mathbb{R}^ d, \mathbb{R})\}\), where \(C(\mathbb{R}^ d, \mathbb{R})\) denotes the space of all continuous functions \(g: \mathbb{R}^ d\to \mathbb{R}\) For \(d=1\) the functions in \(M(\Omega ...

U.S. Extended Continental Shelf Cruise to Map Gaps in Kela and Karin Ridges, Johnston Atoll, Equatorial Pacific Ocean [PDF]

open access: yes, 2014
The objectives for cruise KM14-17 are to map the bathymetry of two gaps in two submarine ridges in the vicinity of Johnston Atoll. One ridge gap occurs along the informally named Keli Ridge (Hein et al., 2005) south of Johnston Atoll and the other ridge ...

Curvature Tuning in Folded Strips Through Hyperstatic Applied Rotations

open access: yesFrontiers in Materials, 2019
Folding a strip of paper generates extremely localized plastic strains. The relaxation of the residual stresses results in a ridge that joins two flat faces at an angle known as the dihedral angle. When constrained isostatically, the strip will be at its

Pattern Transitions in a Soft Cylindrical Shell

open access: yes, 2018
Instability patterns of rolling up a sleeve appear more intricate than the ones of walking over a rug on floor, both characterized as uniaxially compressed soft-film/stiff-substrate systems. This can be explained by curvature effects.

On Multivariate Ridge Regression [PDF]

open access: yesBiometrika, 1987
A multivariate linear regression model with q responses as a linear function of p independent variables is considered with a \(p\times q\) parameter matrix B. The least-squares or normal-theory maximum likelihood estimate of B is deficient in that it takes no account of the `across regression' correlations, and ignores the Stein effect.
