New conticrete inequalities of the Hermite-Hadamard-Jensen-Mercer type in terms of generalized conformable fractional operators via majorization

open access: yesDemonstratio Mathematica, 2023
The Hermite-Hadamard inequality is regarded as one of the most favorable inequalities from the research point of view. Currently, mathematicians are working on extending, improving, and generalizing this inequality.

Multi-agents adaptive estimation and coverage control using Gaussian regression

open access: yes, 2014
We consider a scenario where the aim of a group of agents is to perform the optimal coverage of a region according to a sensory function. In particular, centroidal Voronoi partitions have to be computed.

Imagining Climate and Environmental Transformation in the European Union

open access: yesContemporary European Politics, Volume 4, Issue 1, March 2026.
ABSTRACT The EU is clearly committed to its response to the climate and environmental crisis. Transformative policy solutions and targets have been set within the Union to restore 90% of degraded ecosystems and reach climate neutrality by 2050. The EU also remains one of the biggest donors of climate and environmental development aid.

Harmonic conformable refinements of Hermite-Hadamard Mercer inequalities by support line and related applications

open access: yesMathematical and Computer Modelling of Dynamical Systems
We establish new conformable fractional Hermite-Hadamard (H–H) Mercer type inequalities for harmonically convex functions using the concept of support line.

Urban socioeconomic, vegetation, and mosquito interactions in the United States: Current research and future directions

open access: yesEcosphere, Volume 17, Issue 3, March 2026.
Abstract With the introduction and adaptation of non‐native mosquitoes to cities, vector‐borne diseases are emerging concerns in the United States of America. A growing body of literature suggests that mosquito infestations and associated diseases are a greater burden in socioeconomically disadvantaged areas within the heterogeneous urban ecosystem ...

Bound states of the Duffin-Kemmer-Petiau equation with a mixed minimal-nonminimal vector cusp potential

open access: yes, 2010
The problem of spin-0 and spin-1 bosons subject to a general mixing of minimal and nonminimal vector cusp potentials is explored in a unified way in the context of the Duffin-Kemmer-Petiau theory. Effects on the bound-state solutions due to a short-range

The Jensen-Mercer Inequality with Infinite Convex Combinations

open access: yesMathematical Sciences and Applications E-Notes, 2019
The paper deals with discrete forms of double inequalities related to convex functions of one variable. Infinite convex combinations and sequences of convex combinations are included. The double inequality form of the Jensen-Mercer inequality and its variants are especially studied.

Estimating Treatment Effects With Limited Exogeneity: A Machine Learning Approach to Selection Bias

open access: yesInternational Studies of Economics, Volume 21, Issue 1, Page 2-8, March 2026.
ABSTRACT This paper presents a novel method for estimating treatment effects in cases where prior knowledge of the exogeneity of the treatment variable is limited. We employ a machine learning technique, double selection via Lasso, to identify a robust set of control variables without requiring prior assumptions about their specific identities or ...

SCORING HIGH, PAYING UP, GATING IN: Middle‐class Formation and Asset Inequalities under Digital Capitalism in South Africa

open access: yesInternational Journal of Urban and Regional Research, Volume 50, Issue 2, Page 410-429, March 2026.
Abstract This article examines how modern class dynamics become intertwined with automated classifications and data‐driven regimes of value creation under digital capitalism by demonstrating how housing markets shape asset inequalities and middle‐class formation in South Africa.
