Surface-wave-enabled darkfield aperture for background suppression during weak signal detection [PDF]

open access: yes, 2010
Sensitive optical signal detection can often be confounded by the presence of a significant background, and, as such, predetection background suppression is substantively important for weak signal detection.

Extensive Magmatic Heating of the Lithosphere Beneath the Hawaiian Islands Inferred From Salt Lake Crater Mantle Xenoliths

open access: yesGeochemistry, Geophysics, Geosystems, 2020
An ongoing challenge in studies of the oceanic upper mantle is how intraplate hotspots impact the thermal structure of the lithosphere. To address this issue at the Hawaiian hotspot, we analyze mineral compositions for a petrographically diverse suite of

Does Kirk's Theorem Hold for Multivalued Nonexpansive Mappings?

open access: yesFixed Point Theory and Applications, 2010
Fixed Point Theory for multivalued mappings has many useful applications in Applied Sciences, in particular, in Game Theory and Mathematical Economics.

On Semi-Uniform Kadec-Klee Banach Spaces

open access: yesAbstract and Applied Analysis, 2010
Inspired by the concept of U-spaces introduced by Lau, (1978), we introduced the class of semi-uniform Kadec-Klee spaces, which is a uniform version of semi-Kadec-Klee spaces studied by Vlasov, (1972).

Nonlinear disturbance evolution in a two-dimensional boundary layer along an elastic plate and induced radiated sound [PDF]

open access: yes, 2010
The interaction between a boundary-layer flow and an elastic plate is addressed by direct numerical simulation, taking into account the full coupling between the fluid flow and the flexible wall.

GRMHD/RMHD Simulations and Stability of Magnetized Spine-Sheath Relativistic Jets [PDF]

open access: yes, 2007
A new general relativistic magnetohydrodynamics (GRMHD) code ``RAISHIN'' used to simulate jet generation by rotating and non-rotating black holes with a geometrically thin Keplarian accretion disk finds that the jet develops a spine-sheath structure in ...

Consistent estimation of the proportion of false nulls and FDR for adaptive multiple testing Normal means under weak dependence

open access: yes, 2022
We consider multiple testing means of many dependent Normal random variables that do not necessarily follow a joint Normal distribution. Under weak dependence, we show the uniform consistency of proportion estimators that are constructed as solutions to ...

The fixed point property in direct sums and modulus R(a,X) [PDF]

open access: yes, 2012
We show that the direct sum of Banach spaces $X_{1},..., X_{r}$ with a strictly monotone norm has the weak fixed point property for nonexpansive mappings whenever $M(X_{i})>1$ for each $i=1,...,r$. In particular, $(X_{1} \oplus ...

The MHD Kelvin-Helmholtz Instability II: The Roles of Weak and Oblique Fields in Planar Flows [PDF]

open access: yes, 1997
We have carried out high resolution MHD simulations of the nonlinear evolution of Kelvin-Helmholtz unstable flows in 2 1/2 dimensions. The modeled flows and fields were initially uniform except for a thin shear layer with a hyperbolic tangent velocity ...
