On weighted quasi-arithmetic means which are convex [PDF]

Mathematical Inequalities & Applications, 2019
Summary: We study convexity in the class of weighted quasi-arithmetic means. It turns out that their convexity depends only on the generator, neither on weights, nor on the number of variables. Connections between the convexity of a mean and the convexity of its increasing generators are considered.

Low Latency Global Carbon Budget Reveals Late 2024 Carbon Losses and Contrasting Early 2025 Land Sink Recovery Signals

Advanced Science, EarlyView.
Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...

Convex Functions with Respect to a Mean and a Characterization of Quasi-Arithmetic Means

Real Analysis Exchange, 2004
As pointed out in section 1, the author considers the functional equation \[ f[M(x,y)]=M[f(x),f(y)], \tag{1} \] and the functional inequalities \[ f[M(x,y)]\leq M[f(x),f(y)]\text{ and }f[M(x,y)]\geq M[f(x),f(y)\tag{2} \] (with misprint in the second inequality).

Quasi-arithmetic means of continuous functions

Journal of the Mathematical Society of Japan, 1986
Let I be a proper interval, X a compact Hausdorff space and C(X,I) the set of continuous mappings from X into I. The authors define a mean on C(X,I) as a continuous functional satisfying \(M(a1_ X)=a\) for all \(a\in I\) and Mf\(\leq Mg\) if \(f\leq g\).

Updatable Closed‐Form Evaluation of Arbitrarily Complex Multiport Network Connections

Advanced Electronic Materials, EarlyView.
The inverse design of electrically large wave devices often uses reduced‐order multiport models with discrete optimization, requiring many evaluations of complex interconnections between subsystems that differ only in a few blocks. This paper introduces a closed‐form framework enabling efficient Woodbury low‐rank updates of related, previous ...

Overcoming the Phase Discontinuity Problem in RIS Optimization: A Robust and Scalable Phase‐Aware Deep Regression Framework via Hybrid CNN–LSTM Architecture

Advanced Intelligent Systems, EarlyView.
The phase discontinuity problem—where the cyclic nature of phase angles causes catastrophic errors near the ±π boundary—is a fundamental obstacle in learning‐based reconfigurable intelligent surface (RIS) optimization. A phase‐aware hybrid CNN–LSTM framework resolves this by decomposing phase predictions into sine–cosine components, mapping circular ...

Jensen type inequalities on quasi-arithmetic operator means [PDF]

Scientiae Mathematicae Japonicae, 2011
As a continuation of our previous considerations about the operator order among quasi-arithmetic means [Linear Algebra Appl. 434 (2011), 1228-1237], we study this order with a di erent condition on the spectra. As an application we gave the order among some means. Also, we give similar results for F-order.

A phase 1 study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of PF‐07261271 in healthy participants

British Journal of Clinical Pharmacology, EarlyView.
Aim There is an unmet need for more effective therapies in inflammatory bowel disease (IBD). A single drug that blocks multiple distinct pathogenic pathways may offer therapeutic benefit superior to current monotherapies. PF‐07261271, a bispecific antibody targeting both the p40 subunit of interleukin‐12/23 and tumour necrosis factor‐like cytokine 1A ...

Operational Performance Implications of Circular Economy Implementation: An Empirical Exploration in the Manufacturing Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT The global manufacturing sector has increasingly adopted circular economy (CE) practices to address sustainability challenges and improve operational efficiency. This study explores the impact of five CE practices—reduce, reuse, remanufacture, recycle, and recover—on key operational performance dimensions: quality, speed, dependability ...
