Torsional rigidity on compact Riemannian manifolds with lower Ricci curvature bounds

open access: yesOpen Mathematics, 2015
In this article we prove a reverse Hölder inequality for the fundamental eigenfunction of the Dirichlet problem on domains of a compact Riemannian manifold with lower Ricci curvature bounds.

Some sample path properties of multifractional Brownian motion

open access: yes, 2014
The geometry of the multifractional Brownian motion (mBm) is known to present a complex and surprising form when the Hurst function is greatly irregular.

Analytic aspects of the dilation inequality for symmetric convex sets in Euclidean spaces [PDF]

open access: yesarXiv, 2023
We discuss an analytic form of the dilation inequality for symmetric convex sets in Euclidean spaces, which is a counterpart of analytic aspects of Cheeger's isoperimetric inequality. We show that the dilation inequality for symmetric convex sets is equivalent to a certain bound of the relative entropy for symmetric quasi-convex functions, which is ...

Hölder Type Inequalities for Sugeno Integrals under Usual Multiplication Operations

open access: yesAdvances in Fuzzy Systems, 2019
The classical Hölder inequality shows an interesting upper bound for Lebesgue integral of the product of two functions. This paper proposes Hölder type inequalities and reverse Hölder type inequalities for Sugeno integrals under usual multiplication ...

Refinements of the integral form of Jensen’s and the Lah–Ribarič inequalities and applications for Csiszár divergence

open access: yesJournal of Inequalities and Applications, 2020
In this paper, we give refinements of the integral form of Jensen’s inequality and the Lah–Ribarič inequality. Using these results, we obtain a refinement of the Hölder inequality and a refinement of some inequalities for integral power means and ...

Numerical and Experimental Study of High‐Speed Laser Cutting of Copper Current Collectors: Process Optimization for Quality Assessment

open access: yesAdvanced Materials Technologies, EarlyView.
This study employs a CFD model to simulate laser cutting of copper current collectors used for Li‐Ion battery production. This model predicts cut edge quality by assessing the influence of power, scanner speed, and foil thickness. Defects are classified and an optimal working area is found.

Quantum Optics Parity Effect on Generalized NOON States and Its Implications for Quantum Metrology

open access: yesAnnalen der Physik, Volume 534, Issue 12, December 2022., 2022
A quantum optical‐parity effect is found to emerge in the evolution from generalized NOON states of a two‐level atom or molecule coupled to a cavity field. The parity of the photon number influences the quantum entanglement properties of the system, resulting in a parity‐dependent ability to extract states of the evolving system for precise phase ...

A Theoretical Investigation on Coupled Mass‐charge Transport in a Binary Fluid

open access: yesAdvanced Theory and Simulations, EarlyView.
This study presents a theoretical framework for coupled mass‐charge transport in binary fluids using molecular dynamics simulations. By deriving governing equations from conservation laws and Onsager's theory, the approach introduces generalized diffusivity and electrostatic friction terms.

A Note on the New Ostrowski and Hadamard Type Inequalities via the Hölder–İşcan Inequality

open access: yesAxioms, 2023
For all convex functions, the Hermite–Hadamard inequality is already well known in convex analysis. In this regard, Hermite–Hadamard and Ostrowski type inequalities were obtained using exponential type convex functions in this work.
