Revisiting Fold-Change Calculation: Preference for Median or Geometric Mean over Arithmetic Mean-Based Methods

open access: yesBiomedicines
Background: Fold change is a common metric in biomedical research for quantifying group differences in omics variables. However, inconsistent calculation methods and inadequate reporting lead to discrepancies in results. This study evaluated various fold-

On Approximating the Toader Mean by Other Bivariate Means

open access: yesJournal of Function Spaces, 2019
In the article, we provide several sharp bounds for the Toader mean by use of certain combinations of the arithmetic, quadratic, contraharmonic, and Gaussian arithmetic-geometric means.

One mean to rule them all? The arithmetic mean based egg reduction rate can be misleading when estimating anthelminthic drug efficacy in clinical trials.

open access: yesPLoS Neglected Tropical Diseases, 2020
Animal and human helminth infections are highly prevalent around the world, with only few anthelminthic drugs available. The anthelminthic drug performance is expressed by the cure rate and the egg reduction rate.

Laser Preset of MnOx Layer on High‐Entropy Alloy Surface for Ampere‐Level Ultra‐Stable OER Performance

open access: yesAdvanced Science, EarlyView.
3D printing enables a high entropy alloy‐derived, in situ formed MnOx overlayer that suppresses oxidation–reconstruction and mitigates anodic dissolution, while enhancing electrolyte wetting and bubble release to accelerate interfacial mass transport and OER kinetics.

On the Arithmetic-Geometric mean inequality

open access: yesTamkang Journal of Mathematics, 2013
We obtain some refinements of the Arithmetic--Geometric mean inequality. As an application, we find the maximum value of a multi-variable function.

A Modular Standard Operating Procedure for Standardizing Lithium Metal Interfaces

open access: yesAdvanced Science, EarlyView.
A modular standard operating procedure (SOP) is developed to standardize lithium metal interfaces through sequential etching, brushing, and soaking. By transforming poorly controlled lithium surfaces into chemically uniform and structurally regulated interfaces, the framework improves electrochemical reproducibility, interfacial stability, and ...

A Note on Mixed-Mean Inequalities

open access: yesJournal of Inequalities and Applications, 2010
We give a simpler proof of a result of Holland concerning a mixed arithmetic-geometric mean inequality. We also prove a result of mixed-mean inequality involving the symmetric means.

The arithmetic-geometric-harmonic-mean and related matrix inequalities

open access: yesLinear Algebra and its Applications, 1997
Recently, Sagae and Tanabe defined a geometric mean of positive definite matrices and proved the harmonic-geometric-arithmetic- mean inequality. Here, we give a reversal of these results.

Kirigami‐Cut Pattern Designs for the Enhancement of Sensing Performance Induced by Programmable Out‐of‐Plane Deformation

open access: yesAdvanced Science, EarlyView.
Different kirigami patterns are proposed and the parameters are optimized by comparing the out‐of‐plane deformation behavior. Then, the proposed patterns are fabricated on PVDF film using laser technology. The deformed kirigami‐cut PVDF is embedded into PDMS to construct pressure senor.
