Discrepancy of arithmetic progressions in boxes and convex bodies

open access: yesMathematika, Volume 72, Issue 2, April 2026.
Abstract The combinatorial discrepancy of arithmetic progressions inside [N]:={1,…,N}$[N]:= \lbrace 1, \ldots, N\rbrace$ is the smallest integer D$D$ for which [N]$[N]$ can be colored with two colors so that any arithmetic progression in [N]$[N]$ contains at most D$D$ more elements from one color class than the other.

Subset‐Row Inequalities and Unreachability in Path‐Based Formulations for Vehicle Routing and Scheduling Problems

open access: yesNetworks, Volume 87, Issue 2, Page 111-130, March 2026.
ABSTRACT This work considers branch‐price‐and‐cut algorithms for variants of the vehicle‐routing problem in which subset‐row inequalities (SRIs) are used to strengthen the linear relaxation. SRIs often help to substantially reduce the size of the branch‐and‐bound search tree.

Dynamic Resource Allocation for LEO Satellite Systems Under Heterogeneous Traffic Distributions

open access: yesInternational Journal of Satellite Communications and Networking, Volume 44, Issue 2, Page 199-209, March/April 2026.
ABSTRACT This paper proposes an efficient resource allocation scheme for low Earth orbit (LEO) satellite systems. Taking into account the unique characteristics of LEO systems for 6G communication services, we introduce a dynamic bandwidth and power allocation scheme specifically designed to accommodate highly heterogeneous traffic distributions.

From Certainty to Doubts?: Self‐Efficacy of Preschool, Primary and Secondary School Teachers in Inclusive Education

open access: yesEuropean Journal of Education, Volume 61, Issue 1, March 2026.
ABSTRACT Research yields inconsistent findings regarding predictors of teacher self‐efficacy (TSE) in inclusive education (IE). Following Bandura's theory, this cross‐sectional study analysed predictors of TSE in IE among 3013 teachers from Czech preschool, primary, and secondary schools, where such research is absent.

New Inequalities for GA–h Convex Functions via Generalized Fractional Integral Operators with Applications to Entropy and Mean Inequalities

open access: yesFractal and Fractional
We prove the inequalities of the weighted Hermite–Hadamard type the and Hermite–Hadamard–Mercer type for an extremely rich class of geometrically arithmetically-h-convex functions (GA-h-CFs) via generalized Hadamard–Fractional integral operators (HFIOs).

Planning in management: identifying alternative ways of improving performance toward best practices

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 2, Page 1362-1384, March 2026.
Abstract Planning is an important part of the management of organizations, which deals with the setting of targets that guide the actions needed to improve performance. Decision making is at the essence of planning, as it involves the identification of alternative directions for improvement and the selection of a future course of action.

Local equivalence and refinements of Rasmussen's s‐invariant

open access: yesJournal of Topology, Volume 19, Issue 1, March 2026.
Abstract Inspired by the notions of local equivalence in monopole and Heegaard Floer homology, we introduce a version of local equivalence that combines odd Khovanov homology with equivariant even Khovanov homology into an algebraic package called a local even–odd (LEO) triple.
