Maximal Regularity [PDF]

open access: yes, 2021
AbstractIn this chapter, we address the issue of maximal regularity. More precisely, we provide a criterion on the ‘structure’ of the evolutionary equation $$\displaystyle \left (\overline {\partial _{t,\nu }M(\partial _{t,\nu })+A}\right )U=F $$

Error Propagation in Microwave Soil Moisture and Vegetation Optical Depth Retrievals

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Satellite soil moisture and vegetation optical depth [(VOD); related to the total vegetation water mass per unit area] are increasingly being used to study water relations in the soil-plant continuum across the globe.

Dipole formalism with heavy fermions [PDF]

open access: yes, 2001
We extend the dipole formalism of Catani and Seymour to QCD processes involving heavy fermions. We give the appropriate subtraction terms together with their integrated counterpart. All calculations are done within dimensional regularization.

Stability estimate and regularization for a radially symmetric inverse heat conduction problem

open access: yesBoundary Value Problems, 2017
This paper investigates a radially symmetric inverse heat conduction problem, which determines the internal surface temperature distribution of the hollow sphere from measured data at the fixed location inside it. This is an inverse and ill-posed problem.

Image Reconstruction Algorithm Based on Extreme Learning Machine for Electrical Capacitance Tomography

open access: yesJournal of Harbin University of Science and Technology, 2020
Aiming at the problem that the traditional ECT is not accurate in complex situations, this paper proposes a depth learning based inversion method Through the improvement and optimization of the traditional extreme learning machine, the image feature ...

Iterative CT reconstruction using shearlet-based regularization [PDF]

open access: yes, 2012
In computerized tomography, it is important to reduce the image noise without increasing the acquisition dose. Extensive research has been done into total variation minimization for image denoising and sparse-view reconstruction. However, TV minimization

Regular Partitions of Regular Graphs [PDF]

open access: yesCanadian Mathematical Bulletin, 1978
In the study of the combinatorial structure of edge-graphs of convex polytopes one may ask whether a given graph possesses a partition consisting of certain kinds of subgraphs.In this paper we describe some special partitions of 3-valent and 4-valent graphs.

Hadamard regularization [PDF]

open access: yesJournal of Mathematical Physics, 2000
Motivated by the problem of the dynamics of point-particles in high post-Newtonian (e.g., 3PN) approximations of general relativity, we consider a certain class of functions which are smooth except at some isolated points around which they admit a power-like singular expansion.

Entropy convergence in early bilinguals’ syntactic packaging

open access: yesFrontiers in Psychology, 2022
A core question in developmental and cognitive research concerns the way linguistic variation affects the acquisition process. Previous research on monolinguals suggests that children, but not adults, tend to regularize inconsistent input, resulting in ...
