Comments on the calculation of the specific growth rate in experiments with untagged individuals
Scientia Marina, 2015 The specific growth rate, G, is widely used in articles dealing with the growth of aquatic organisms under experimental conditions. When individuals are untagged, the arithmetic mean of G for a group of animals must be calculated from weight geometric ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells
Advanced Materials, EarlyView.This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Sharp inequalities for the Neuman-Sandor mean in terms of arithmetic and contra-harmonic means
Journal of Numerical Analysis and Approximation Theory, 2013 In this paper, we find the greatest values \(\alpha\) and \(\lambda\), and the least values \(\beta\) and \(\mu\) such that the double inequalities \[C^{\alpha}(a,b)A^{1-\alpha}(a,b)

Two sharp double inequalities for Seiffert mean
Journal of Inequalities and Applications, 2011 In this paper, we establish two new inequalities between the root-square, arithmetic, and Seiffert means. The achieved results are inspired by the paper of Seiffert (Die Wurzel, 29, 221-222, 1995), and the methods from Chu et al. (J. Math.

A new analogue of Gauss' functional equation
International Journal of Mathematics and Mathematical Sciences, 1995 Gauss established a theory on the functional equation (Gauss' functional equation) f(a+b2,ab)=f(a,b) (a,b>0), where f:R+×R+→R is an unknown function of the above equation.

Iterated Quasi-Arithmetic Mean-Type Mappings [PDF]
, 2014 For a family of quasi-arithmetic means satisfying certain smoothness condition we majorize the speed of convergence of the iterative sequence of self-mappings having a mean on each entry, described in the definition of Gaussian product, to relevant mean ...

Evolution of Materials and Device Stacks for HfO2‐Based Ferroelectric Memories
Advanced Materials Interfaces, EarlyView.This review summarizes engineering strategies for HfO2 based ferroelectric memories with focus on FeCAP and FeFET structures. It describes how dopant design, stress effects, and interface engineering improve the bulk ferroelectric response. It further discusses how channel engineering supports reliable memory characteristics and scalable integration ...

Operator inequalities among arithmetic mean, geometric mean and harmonic mean [PDF]
, 2014 We give an upper bound for the weighted geometric mean using the weighted arith- metic mean and the weighted harmonic mean. We also give a lower bound for the weighted geometric mean. These inequalities are proven for two invertible positive operators.
