A decay estimate for a wave equation with trapping and a complex potential
wave equation decay estimate complex potential Analysis of PDEs
2011/9/19
Abstract: In this brief note, we consider a wave equation that has both trapping and a complex potential. For this problem, we prove a uniform bound on the energy and a Morawetz (or integrated local e...
BLR Physical Conditions in Extreme Population A Quasars: a Method to Estimate Central Black Hole Mass at High Redshift
Physical Conditions Extreme Population Quasars
2011/10/10
We describe a method for determination of physical conditions in the broad line regions of a significant subsample of Seyfert-1 nuclei and quasars. Several diagnostic ratios based on intermediate (AlI...
Estimate of halo ellipticity as a function of radius with flexions
cosmology – gravitational lensing – fl exion – dark matter halo
2011/9/29
The cold dark matter theory predicts triaxial dark matter haloes. The radial distribution of halo ellipticity depends on baryonic processes and the nature of dark matter particles (collisionless or co...
A lower bound on blowup rates for the 3D incompressible Euler equation and a single exponential Beale-Kato-Majda estimate
lower bound blowup rates 3D incompressible Euler exponential Beale-Kato-Majda estimate
2011/8/23
Abstract: We prove a Beale-Kato-Majda criterion for the loss of regularity for solutions of the incompressible Euler equations in $H^{s}(\R^3)$, for $s>\frac52$. Instead of double exponential estimate...
ion functions quantify super-resolution images and estimate apparent clustering due to over-counting
Correlation functions quantify super-resolution images estimate apparent clustering due to over-counting
2011/9/9
We present an analytical method to quantify clustering in super-resolution localization images of static surfaces in two dimensions. The method also describes how over-counting of labeled molecules co...

Temperature- and cholesterol-induced changes in eicosapentaenoic acid limitation of Daphnia magnadetermined by a promising method to estimate growth saturation thresholds
Temperature cholesterol-induced changes in eicosapentaenoic acid limitation Daphnia magnadetermined a promising method estimate growth saturation thresholds
2014/4/8
We present data on eicosapentaenoic acid (EPA)-limited growth responses ofDaphnia magnaunder different temperatures and different dietary cholesterol availabilities to assess how EPA growth saturation...
An Interior Gradient Estimate for a class of Second Order Partial Differential Inequalities
Interior Gradient Estimate class of Second Order Partial Differential Inequalities
2011/2/22
In this paper, we show a uniform gradient estimate for functions u defined on a domain
in Euclidian space RN which satisfy a system of N second order partial differential inequalities of the followi...
Energy estimate for initial data on a characteristic cone
Energy estimate initial data characteristic cone
2011/3/2
The Einstein equations in wave map gauge are a geometric second order system for a Lorentzian metric. To study existence of solutions of this hyperbolic quasi diagonal system with initial data on a ch...
A new approach to estimate the mix efficiency in data envelopment analysis
Data Envelopment Analysis Mix efficiency
2010/9/26
Recently, in Data Envelopment Analysis (DEA) methodology, there are two type of efficiency measurement; radial and non-radial measure represented by the Charnes-Cooper-Rhodes (CCR) and the slack-based...
On the sharpness of a certain spectral stability estimate for the Dirichlet Laplacian
Elliptic equations Dirichlet boundary conditions stability of eigenvalues
2011/2/25
We consider a spectral stability estimate by Burenkov and Lamberti concerning the variation of the eigenvalues of second order uniformly elliptic operators on variable open sets in the N-dimensional e...

2011/2/25
We consider a two dimensional magnetic Schr¨odinger operator with a spatially stationary random magnetic field. We assume that the magnetic field has a positive lower bound and that it has Fourier mod...
"Discrepant hardenings" in cosmic ray spectra: a first estimate of the effects on secondary antiproton and diffuse gamma-ray yields
Discrepant hardenings cosmic ray spectra the effects on secondary antiproton
2011/1/11
Recent data from CREAM seem to confirm early suggestions that primary cosmic ray spectra at few TeV/nucleon are harder than in the 10-100 GeV range. Also, helium and heavier nuclei spectra appear syst...
