Influences of substrate pretreatments and Ti/Cr interlayers on the adhesion and hardness of CrAlSiN and TiAlSiN films deposited on Al2O3 and ZrO2-8Y2O3 thermal barrier coatings

open access: yesResults in Physics, 2019
Using atmospheric plasma spraying (APS), ceramic Al2O3 and ZrO2-8Y2O3 thermal barrier coatings (TBC) were applied on AISI H11 (1.2343) and subsequently polished to serve as a substrate to magnetron sputter CrAlSi7.5N and TiAlSi7.9N films.

Improving Small-Molecule Force Field Parameters in Ligand Binding Studies

open access: yesFrontiers in Molecular Biosciences, 2021
Small molecules are major players of many chemical processes in diverse fields, from material science to biology. They are made by a combination of carbon and heteroatoms typically organized in system-specific structures of different complexity.

Degenerate Euler zeta function

open access: yes, 2015
Recently, T. Kim considered Euler zeta function which interpolates Euler polynomials at negative integer (see [3]). In this paper, we study degenerate Euler zeta function which is holomorphic function on complex s-plane associated with degenerate Euler ...

What Is a Theorem (in Practice)? The Role of Metamathematics in the Making of Mathematics

open access: yesTrilogía Ciencia Tecnología Sociedad, 2021
This article advocates the benefits of a sociological perspective for the philosophy of mathematical practice. Drawing from the literature of the sociology of sciences, it defends a community-centered approach of the study of mathematical practice and ...

Transferring chemical and energetic knowledge between molecular systems with machine learning

open access: yesCommunications Chemistry, 2023
Machine learning algorithms are widely employed for molecular simulations, but there are likely many yet unexplored routes for the prediction of structural and energetic properties of biologically relevant systems.

Divergence of the multilevel Monte Carlo Euler method for nonlinear stochastic differential equations

open access: yes, 2013
The Euler-Maruyama scheme is known to diverge strongly and numerically weakly when applied to nonlinear stochastic differential equations (SDEs) with superlinearly growing and globally one-sided Lipschitz continuous drift coefficients.

An Onsager Singularity Theorem for Turbulent Solutions of Compressible Euler Equations [PDF]

open access: yes, 2017
We prove that bounded weak solutions of the compressible Euler equations will conserve thermodynamic entropy unless the solution fields have sufficiently low space-time Besov regularity.

A learning based impedance control strategy implemented on a soft prosthetic wrist in joint-space

open access: yesFrontiers in Robotics and AI
The development of advanced control strategies for prosthetic hands is essential for improving performance and user experience. Soft prosthetic wrists pose substantial control challenges due to their compliant structures and nonlinear dynamics. This work

On the Twisted q-Euler numbers and polynomials associated with basic q-l-functions

open access: yes, 2006
One purpose of this paper is to construct twisted q-Euler numbers by using p-adic invariant integral on Zp in the sense of fermionic. Finally, we consider twisted Euler q-zeta function and q-l-series which interpolate twisted q-Euler numbers and ...
