Fixed point theory for multivalued φ-contractions

Fixed Point Theory and Applications, 2011
The purpose of this paper is to present a fixed point theory for multivalued φ-contractions using the following concepts: fixed points, strict fixed points, periodic points, strict periodic points, multivalued Picard and weakly Picard operators ...

Fixed point results for generalized convex orbital Lipschitz operators

Demonstratio Mathematica
Krasnoselskii’s iteration is a classical and important method for approximating the fixed point of an operator that satisfies certain conditions. Many authors have used this approach to obtain several famous fixed point theorems for different types of ...

On the solution of Steinhaus functional equation using weakly Picard operators

Filomat, 2011
In this paper we obtain existence results regarding the solutions g of a Steinhaus type functional equation of the form g(x)+ g(f(x))= F(x), under the significantly weaker assumption that f is a weakly Picard operator. The solutions are given in terms of sums of either convergent series or divergent series but summable by some method of ...

The optimality‐based active region model for fingering flow in the vadose zone: Theory, model validation, and generalization

Vadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Traditional macroscopic models for water flow in the vadose zone often assume local equilibrium within a representative element volume. However, under fingering flow this assumption breaks down on a macroscale involving sub‐grid figuring because local equilibrium does not hold between the fingering and non‐fingering domains.

Meso‐ to Submesoscale Variability of Particulate Carbon Export Captured by a Glider‐Camera System in the Northeast Atlantic During the APERO Campaign

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Between 9 June and 6 July 2023 a SeaExplorer glider equipped with an Underwater Vision Profiler (UVP6), surveyed frontal structures between a cyclonic and two anticyclonic eddies in the Northeast Atlantic as part of the APERO cruise (Assessing marine biogenic matter Production, Export and Remineralization: from the surface to the dark Ocean ...

Existence and Stability of Solutions for p-Proportional ω-Weighted κ-Hilfer Fractional Differential Inclusions in the Presence of Non-Instantaneous Impulses in Banach Spaces

Fractal and Fractional
In this work, we introduce a new definition for the fractional differential operator that generalizes several well-known fractional differential operators.

HTLV‐1 Tax Reshapes the DNA‐Binding Pattern of Transcription Factor IRF4 and Disrupts Host Gene Regulation

Cancer Science, Volume 117, Issue 5, Page 1497-1509, May 2026.
Proteomic mapping of Tax complexes in HTLV‐1–infected T‐cells identified IRF4 as a Tax interactor. Chromatin profiling showed Tax reprograms IRF4 occupancy with H3K27ac gains at super‐enhancers; Tax–IRF4 co‐expression altered chromatin accessibility and transcription, and ATL‐associated IRF4 mutants partially phenocopied these changes.

The Development of Temporal Memory for Complex Events

Developmental Science, Volume 29, Issue 3, May 2026.
ABSTRACT Remembering when past events occurred is a key component of episodic memory, yet its developmental trajectory remains only partially understood. This study examined how children aged 6 and 10, compared to young adults, recall the timing of events embedded in an 11‐min cartoon.

Genome‐Wide Homozygosity Predicts Inbreeding Depression in the Hihi/Stitchbird (Notiomystis cincta) Better Than Realised Load

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Population declines result in increasingly small populations, which often experience an increase in inbreeding. Inbreeding may be negatively associated with fitness traits like survival and reproduction, that is, inbreeding depression, and is therefore detrimental to population persistence and adaptive potential.
