Invariance of quasi-arithmetic means with function weights

Journal of Mathematical Analysis and Applications, 2009
In this paper some existence results are presented for the functional equation \[ \begin{multlined} \lambda(x,y)\phi^{-1}\left(\mu(x,y)\phi(x)+(1-\mu(x,y)\right)\phi(y)\\ +(1-\lambda(x,y))\psi^{-1}\left( \nu (x,y)\psi(x)+(1-\nu(x,y)\psi(y)\right)\\ =\lambda(x,y)x+(1-\lambda(x,y))y, \end{multlined} \] where \(\phi, \psi: I\to {\mathbb R}\) are ...

Sleep Deprivation in Mice: Looking Beyond the Slow Wave Rebound

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep is a fundamental process supporting the dynamic regulation of neural function. Emerging methods have proposed that the aperiodic components of brain signals (such as the spectral slope, spectral intercept, and spectral knee), in addition to entropy‐based measures, offer robust empirical markers of neural states.

Structure and Computation

Noûs, EarlyView.
ABSTRACT It is a truism of mathematics that differences between isomorphic number systems are irrelevant to arithmetic. This truism is deeply rooted in the modern axiomatic method and underlies most strands of arithmetical structuralism, the view that arithmetic is about some abstract number structure.

Confidence Intervals for Price Discovery

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper discusses asymptotic and bootstrap confidence intervals for multivariate permanent‐transitory decompositions of cointegrated vector autoregressive I(1) systems, with a focus on price discovery. Alternative estimators of the permanent components are compared in terms of efficiency also under separable linear restrictions on the ...

Quasi-arithmetic Means Inequalities Criteria for Differentiable Functions

Journal of Mathematics Research, 2015
Quasi-arithmetic means are defined for continuous, strictly monotone functions. In the case that functions are twice differentiable, we obtained criteria for inequalities between finite number of quasi-arithmetic means  in additional and multiplicative case. Applications for H\"older and Minkowski type inequalities are given.

DNAwhisper: An Integrated Deep Learning Pyramidal Framework for Multi‐Trait Genomic Prediction and Adaptive Marker Prioritisation

Plant Biotechnology Journal, EarlyView.
ABSTRACT Genomic selection (GS) is critical for accelerating genetic gain in modern plant breeding. Deep learning approaches offer powerful non‐linear representation capabilities for modelling non‐additive effects. However, their application in GS remains restricted, as high‐dimensional, low‐sample and noisy data hinder the identification of ...

Determination of the roughness of a precision surface by the correlation method of image processing of its microrelief

Физика волновых процессов и радиотехнические системы
Background. Numerous studies have established that the roughness of the microrelief of the working surface of various parts of machines and mechanisms largely determines their operational reliability and durability.

The Impacts of Problem‐Posing Intervention on the Mathematical Proficiency of Undergraduate Developmental Mathematics Students' Developmental Mathematics

School Science and Mathematics, EarlyView.
ABSTRACT This study investigates the impact of problem‐posing on the mathematical proficiency and engagement of 56 Developmental Mathematics (DM) students enrolled in a noncredit college mathematics course. Using a quasi‐experimental design, one of two existing classes was selected as the experimental group and received a 5‐week intervention focused on

Rational points on even‐dimensional Fermat cubics

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...
