Python programs to apply regularized derivatives in the magnetic tilt derivative and gradient intensity data processing: A graphical procedure to choose the regularization parameter

Applied Computing and Geosciences, 2023
The Tikhonov regularization parameter is a key parameter controlling the smoothness degree and oscillations of a regularized unknown solution. Usual methods to determine a proper parameter (L-curve or the discrepancy principle, for example) are not ...

Equilibrium stacks for a three-person game on a product of staircase-function continuous and finite strategy spaces

Foundations of Computing and Decision Sciences, 2022
A method of solving a three-person game defined on a product of staircase-function strategy spaces is presented. The spaces can be finite and continuous.

Validation of a Bayesian Adaptive Estimation Technique in the Stop-Signal Task. [PDF]

PLoS ONE, 2016
The Stop Signal Task (SST), a commonly used measure of response inhibition, uses standard psychophysical methods to gain an estimate of the time needed to withhold a prepotent response.

Evaluation of animal models and methods for assessing shoulder function after rotator cuff tear: A systematic review

Journal of Orthopaedic Translation, 2021
Background and objective: Restoring the shoulder function is a crucial demand of patients with rotator cuff (RC) tears. Most preclinical studies only focused on biological and mechanical measurements.

Fractal Calculus of Functions on Cantor Tartan Spaces

Fractal and Fractional, 2018
In this manuscript, integrals and derivatives of functions on Cantor tartan spaces are defined. The generalisation of standard calculus, which is called F η -calculus, is utilised to obtain definitions of the integral and derivative of ...

Perspective: Kohn-Sham density functional theory descending a staircase [PDF]

The Journal of Chemical Physics, 2016
This article presents a perspective on Kohn-Sham density functional theory (KS-DFT) for electronic structure calculations in chemical physics. This theory is in widespread use for applications to both molecules and solids. We pay special attention to several aspects where there are both concerns and progress toward solutions. These include: 1.

Diffusion on Middle-ξ Cantor Sets

Entropy, 2018
In this paper, we study Cζ-calculus on generalized Cantor sets, which have self-similar properties and fractional dimensions that exceed their topological dimensions.

Generalized Devil's staircase and RG flows

Nuclear Physics B, 2023
We discuss a two-parameter renormalization group (RG) flow when parameters are organized in a single complex variable, τ, with modular properties. Throughout the work we consider a special limit when the imaginary part of τ characterizing the disorder ...
