The arithmetic-geometric mean inequality (I)

, 2016
The arithmetic-geometric mean inequality: √ab ≤ (a+b)/2, for a,b ≥ 0. The figure shows that (a+b)²-(a-b)²=4ab, therefore √ab = √[(a+b)²-(a-b)²]/4 ≤ √[(a+b)²]/4 = (a+b)/2Ensino Médio ...

Application of Differential Subordinations to the Arithmetic–Geometric Means by Using an Operator

Journal of Mathematics
This study investigates differential subordination involving arithmetic and geometric mean approaches associated with a previously introduced operator. While earlier studies considered cases where the dominant function was convex or linear, the present ...

Some applications related to the arithmetic-geometric mean inequality

In this paper, we introduce some refinements of the arithmetic-geometric-logarithmic mean inequality. The obtained results allow us to get new inequalities for the inverse sine function and refined inequalities for well-known hyperbolic inequalities ...

Re‐Thinking Electronic Circuit Design Through Emerging Reconfigurable Field Effect Transistors

Advanced Science, EarlyView.
Graphical illustration of reconfigurable field effect transistor (RFET) operation modes, including n‐type, p‐type, and ambipolar transport, as well as their areas of application discussed in this review: digital circuit design, analog circuit design, post‐Shannon computing, and sensing. ABSTRACT Reconfigurable field‐effect transistors, short RFETs, are

Spatiotemporal Computational Meta‐Imager for Broadband Dual‐Layer Optical Convolution

Advanced Science, EarlyView.
A single‐layer polarization‐multiplexed meta‐imager achieves factorized dual‐layer broadband convolution via spatiotemporal kernel decomposition. Fixed Bessel‐vortex bases and time‐sequential liquid‐crystal modulation deliver tunable signed weights and in‐situ fabrication‐error compensation. Experiments verify improved classification performance across

Optimal Inequalities among Various Means of Two Arguments

Abstract and Applied Analysis, 2009
We establish two optimal inequalities among power mean Mp(a,b)=(ap/2+bp/2)1/p, arithmetic mean A(a,b)=(a+b)/2, logarithmic mean L(a,b)=(a−b)/(log⁡a−log⁡b), and geometric mean G(a,b)=ab.

Magnetoelectric Multiferroics for the Next‐Generation Ultralow‐Power Electronics

Advanced Science, EarlyView.
Magnetoelectric coupling provides a unifying route from electric‐field control of magnetic order to non‐volatile MeRAM, MESO logic, and emerging antiferromagnetic and magnonic devices. By connecting switching physics with device benchmarks, material platforms, and integration strategies, distinctive technological opportunities are identified alongside ...

Which is the Correct Discount Rate? Arithmetic Versus Geometric Mean

, 2020
The paper revisits the two major concepts for average historical returns, i.?e., the arithmetic mean and the geometric mean, in order to clarify which approach must be used for which application. Conducting a rigorous derivation with a geometric Brownian
