Resolvent expansions for the Schrödinger operator on the discrete half-line [PDF]
, 2016 Simplified models of transport in mesoscopic systems are often based on a small sample connected to a finite number of leads. The leads are often modelled using the Laplacian on the discrete half-line N.

Resolvent estimates and decomposable extensions of generalized Cesàro operators
Journal of Functional Analysis, 2010 Let \(H(\mathbb D)\) be the space of all holomorphic functions in the unit disk \(\mathbb D\). For \(g\in H(\mathbb D)\), the generalized Cesàro operator \({\mathfrak C}_g\) is defined by \[ {\mathfrak C}_g f(z)=\frac{1}{z}\int_0^z f(w)g'(w) \,dw, \quad z\in\mathbb D,\;f\in H(\mathbb D).

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Subtotal hippocampal resection can leave residual hippocampal tissue, yet the immediate postoperative electrophysiologic evolution of such remnants is unknown. We describe a patient with drug‐resistant temporal lobe epilepsy in whom a hippocampal remnant was continuously monitored using a responsive neurostimulator (RNS) following subtotal ...

Periodic Solutions of the Euler-Bernoulli Equation for Vibrations of a Beam with Fixed Ends
Современные информационные технологии и IT-образование, 2020 The problem of time-periodic solutions of the quasilinear equation of forced vibrations of an I-beam with fixed ends is investigated. The nonlinear term and the right-hand side of the equation are time-periodic functions.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Facioscapulohumeral muscular dystrophy (FSHD) is one of the most debilitating and common muscular dystrophies. Despite its severity, no approved therapy exists for FSHD patients. However, several therapeutic candidates are currently under development, and some have recently entered clinical trials, marking the need for reliable ...

Growth conditions, compact perturbations and operator subdecomposability, with applications to generalized Cesàro operators [PDF]
, 2004 We adapt recent results of Albrecht and Ricker to obtain conditions under which growth constraints on the left resolvent of a Banach space operator are preserved under suitable perturbations.
