together with appropriate boundary conditions, in the space Lw of functions square integrable with respect to the weight w, i.e., the normsquare of the space is ‖u‖2 = ∫ |u|2w. A basic assumption for… (More)

The Homeobox (Hox) genes direct the development of tetrapod digits. The expression of Hox genes may be influenced by endogenous sex steroids during development. Manning (Digit ratio. New Brunswick,… (More)

Adaptions of weighted rank regression to the accelerated failure time model for censored survival data have been successful in yielding asymptotically normal estimates and flexible weighting schemes… (More)

Dedicated to the memory of Leonid R. Volevič. In this paper, we combine results on extensions of operators with recent results on the relation between the M-function and the spectrum, to examine the… (More)

Algebro-geometric potentials q of the one-dimensional Schrödinger operator L = −d2/dx2 + q are a small but important class of potentials with a number of rather nice properties. Their name is due to… (More)

It is proved in this paper that super-exponentially decaying, possibly non-selfadjoint perturbations of the free Jacobi operator are uniquely determined by the location of all their eigenvalues and… (More)

We present a spectral and inverse spectral theory for the zero dispersion spectral problem associated with the Camassa-Holm equation. This is an alternative approach to that in [10] by Eckhardt and… (More)

We consider the spectral function ρ(μ) (μ ≥ 0) for the Sturm-Liouville equation y ′′ +(λ− q)y = 0 on [0,∞) with the boundary condition y(0) = 0 and where q has slow decay O(x−α) (a > 0) as x → ∞. We… (More)

A uniqueness result for the recovery of the electric and magnetic coefficients in the time-harmonic Maxwell equations from local boundary measurements is proven. No special geometrical condition is… (More)
