Sergey Simonovount of water held in the tissue, and an inverse relationship between sulfur concentration and the rate of fluid flow from the disk during compressive loading. Elemental concentrations were measured for sulfur, potassium, sodium, chlorine, phosphorus and calcium in each area of the disk by electron

A Mathematical Study of Quantum Revivals and Quantum Fidelity,mainly in the semiclassical framework. We also describe the exact properties of the quantum fidelity (also called Loschmidt echo) for the case of explicit quadratic plus inverse quadratic time-periodic Hamiltonians and establish that the quantum fidelity equals one for exactly the times where the cl

On Relations Between Stable and Zeno Dynamics in a Leaky Graph Decay Model,and the stable one which governs time evolution of the dot states in the absence of the wire. We analyze the weak coupling case and argue that the two time evolutions can differ significantly only at times comparable with the lifetime of the unstable system undisturbed by perpetual measurement.

On the Spectrum of Partially Periodic Operators, ∈ ℝ.. We assume that Ω is unbounded with respect to the variable . ∈ ℝ and that . decays with respect to this variable. . may contain a singular term supported on the boundary..We develop a scattering theory for . and present an approach to prove absence of singular continuous spectrum. Moreover, w

Functional Model for Singular Perturbations of Non-self-adjoint Operators,on-self-adjoint perturbation of a self-adjoint operator . and that the spectrum of the operator . is absolutely continuous we are able to establish a concise resolvent formula for the singular perturbations of the class considered and to establish a model representation of it in the dilation space a
