Neuman-Sandor mean, asymptotic expansions and related inequalities

open access: yes, 2015
The subject of this paper is a systematic study of inequalities of the form $$ (1-\mu) M_1+\mu M_3 \leq M_2 \leq (1-\nu) M_1+\nu M_3 $$ which cover Neuman-S\'andor mean and some classical means. Furthermore, following inequalities with optimal parameters

A practical review on the measurement tools for cellular adhesion force

open access: yes, 2019
Cell cell and cell matrix adhesions are fundamental in all multicellular organisms. They play a key role in cellular growth, differentiation, pattern formation and migration.

Managing the Threat of Subsidized Predators for a Threatened Shorebird

open access: yesAnimal Conservation, EarlyView.
Subsidized predators—native predators that have become more common due to human activities—challenge the persistence of many at‐risk prey species and require creative solutions beyond lethal predator control. In an 8‐year study, we placed small wire cages over western snowy plover nests that allow passage of plovers, but not their predators, and ...

On the p-Version of the Schwab-Borchardt Mean

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2014
This paper deals with a one-parameter generalization of the Schwab-Borchardt mean. The new mean is defined in terms of the inverse functions of the generalized trigonometric and generalized hyperbolic functions.

When and why to give shorebirds a head start

open access: yesConservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

Flooding and a complex predator community drive American oystercatcher nest and chick survival in Virginia

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We investigated low American oystercatcher (Haematopus palliatus) productivity in the Virginia barrier islands, which historically supported high oystercatcher reproductive success. We found that chick survival was lower than nest survival, and that management may need to adapt to address evolving threats from coastal flooding and a multi‐guild ...

Optimal bounds for Neuman-Sándor mean in terms of one-parameter centroidal mean

open access: yes, 2018
In the paper, we find the best possible parameters $\alpha,\beta \in ({0,1})$ and $\lambda, \mu \in ({1/2,1})$ such that the double inequalities $\sqrt{\alpha E^{2}( {a,b})+(1-\alpha)A^{2}({a,b})} 0$ with $a\ne b$, here $NS(a,b) = ({a-b}) / [2sin{h^{-1}}$

Groundwater Age and Nonpoint Source Pollutant Mixing in Alluvial Aquifer Wells: Comparing the Role of Diffusion, Dispersion, Aquifer Heterogeneity, and Well Screen Length

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Understanding the mixing of groundwater age and of nonpoint source (NPS) pollutants in water samples is crucial for interpreting age tracer and NPS pollutant data from production wells. Traditionally, diffusion and mechanical dispersion have been key mixing processes embedded in physical models for simulating and interpreting age tracer and ...

A Robust and Efficient Continuous‐Differentiable Seepage Face Boundary Condition for Dynamic Groundwater Modeling

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Seepage boundary conditions are commonly used in groundwater simulations to allow groundwater to discharge at the upper surface of the model when groundwater head exceeds atmospheric pressure. However, the extent and transient behavior of the seepage zone are often unknown a priori and difficult to predict.
