Singular perturbations to semilinear stochastic heat equations [PDF]
Probability theory and related fields, 2010 We consider a class of singular perturbations to the stochastic heat equation or semilinear variations thereof. The interesting feature of these perturbations is that, as the small parameter ε tends to zero, their solutions converge to the ‘wrong’ limit,

Relationship Between Neurologic Symptoms and Signs and FMR1 Genotype in Premutation Carriers
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Fragile X‐associated Tremor/Ataxia Syndrome (FXTAS) is the most severe late‐onset condition caused by a premutation in the FMR1 gene, characterized by expanded CGG triplet repeats of 55–200. Clinical presentations of FXTAS, including gait ataxia, kinetic tremor, cognitive decline, and rare Parkinsonism, are linked to ...

Fluctuations in a Ho\v{r}ava-Lifshitz Bouncing Cosmology
, 2009 Ho\v{r}ava-Lifshitz gravity is a potentially UV complete theory with important implications for the very early universe. In particular, in the presence of spatial curvature it is possible to obtain a non-singular bouncing cosmology.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Cognitive impairment is a common non‐motor symptom in Multiple Sclerosis (MS), negatively affecting autonomy and Quality of Life (QoL). Innovative rehabilitation strategies, such as semi‐immersive virtual reality (VR) and computerized cognitive training (CCT), may offer advantages over traditional cognitive rehabilitation (TCR ...

Hyperbolic-parabolic singular perturbations in general regions
Le Matematiche, 1991 We consider a singular perturbations problem for the inhomogeneous damped wave equation and the inhomogeneous heat equation with moving boundary. We give rigorous and explicit estimates and show the uniform convergence.

Some Remarks on 1D Schrödinger Operators With Localized Magnetic and Electric Potentials
Frontiers in Physics, 2019 One-dimensional Schrödinger operators with singular perturbed magnetic and electric potentials are considered. We study the strong resolvent convergence of two families of the operators with potentials shrinking to a point.

Robustness Analysis of a Class of Decentralized Control Systems [PDF]
Modeling, Identification and Control, 1986 The paper presents a method for analysing the robustness properties of a class of decentralized control systems. Perturbations both in local and in interconnection parameters are dealt with. The method is based on the use of singular values.

Handling a Commensurate, Incommensurate, and Singular Fractional-Order Linear Time-Invariant System
Axioms, 2023 From the perspective of the importance of the fractional-order linear time-invariant (FoLTI) system in plenty of applied science fields, such as control theory, signal processing, and communications, this work aims to provide certain generic solutions ...

Dimension of the exceptional set in the Aronszajn-Donoghue theorem for finite rank perturbations
, 2020 The classical Aronszajn-Donoghue theorem states that for a rank one perturbation of a self-adjoint operator (by a cyclic vector) the singular parts of the spectral measures of the original and perturbed operators are mutually singular.
