A Macroscopic Multifractal Analysis of Parabolic Stochastic PDEs [PDF]
, 2017 It is generally argued that the solution to a stochastic PDE with multiplicative noise—such as $${\dot{u}=\frac12 u''+u\xi}$$u˙=12u′′+uξ , where $${\xi}$$ξ denotes space-time white noise—routinely produces exceptionally-large peaks that are ...

Analysis of Intrinsic Mode Functions: A PDE Approach [PDF]
IEEE Signal Processing Letters, 2010 The empirical mode decomposition is a powerful tool for signal processing. Because of its original algorithmic, recent works have contributed to its theoretical framework. Following these works, some mathematical contributions on its comprehension and formalism are provided.

Applications of PDEs inpainting to magnetic particle imaging and corneal topography [PDF]
Opuscula Mathematica, 2019 In this work we propose a novel application of Partial Differential Equations (PDEs) inpainting techniques to two medical contexts. The first one concerning recovering of concentration maps for superparamagnetic nanoparticles, used as tracers in the ...

Optimal systems and group invariant solutions for a model arising in financial mathematics
Mathematical Modelling and Analysis, 2009 We consider a bond‐pricing model described in terms of partial differential equations (PDEs). Classical Lie point symmetry analysis of the considered PDEs resulted in a number of point symmetries being admitted.

Learning local Dirichlet-to-Neumann maps of nonlinear elliptic PDEs with rough coefficients* [PDF]
ESAIM: Proceedings and SurveysPartial Differential Equations (PDEs) involving high-contrast and oscillating coefficients are common in scientific and industrial applications. Numerically approximating these PDEs is a challenging task, which can be addressed, for example, through ...

Asymptotic analysis of the biharmonic Schrödinger equation with fractional damping
Boundary Value ProblemsIn this paper, we study the decay behavior of solutions to the biharmonic Schrödinger equation under the effect of internal fractional damping. By employing semigroup theory and energy methods, we establish well-posedness results and investigate the long-

Advanced Functional Materials, EarlyView.This study reports a self‐powered InGaAs nanowire photodetector achieving single‐photon‐level sensitivity in the shortwave infrared at non‐cryogenic temperatures. The device demonstrates high‐speed imaging capabilities even under extremely low‐flux conditions.
