Bridging Dimensions in STEAM Education: Linking 2D Function Art and 3D Modeling Using GeoGebra

School Science and Mathematics, EarlyView.
ABSTRACT This study examines a constructionist‐oriented STEAM learning activity in which Grade 11 students used GeoGebra 3D to model bridges. Building on prior work in function art, the project extended mathematical art‐making from two‐dimensional representations to three‐dimensional structures, emphasizing the use of functions, geometric ...

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

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 ...

Four‐Level Overlapping Schwarz as Multigrid Coarse Solver for Incompressible Non‐Newtonian Flow in Complex Geometries

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT For complex geometries, the coarse problem of geometric multigrid can be too large to be solved by a direct solver. Here, we report on the use of domain decomposition applied to the multigrid coarse problem. Additive overlapping Schwarz methods are domain decomposition methods for the iterative solution of partial differential equations whose ...

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 ...

Asymmetric Migration Shapes Genetic Structure of the Invasive Avian Vampire Fly (Philornis downsi) Across the Galápagos Islands

Molecular Ecology, Volume 35, Issue 21, November 2026.
ABSTRACT Biological invasions on islands provide a natural framework to study how dispersal and connectivity influence evolutionary and ecological processes. The avian nest parasitic fly, Philornis downsi—first recorded in Darwin's finch nests in 1997—causes high mortality in endemic land birds, yet its inter‐island and sex‐specific patterns of ...

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.

Weakly Picard pairs of some multivalued operators

Mathematical Communications, 2003
The purpose of this paper is to present a partial answer to the following problem: Let (X,d) be a metric space and $T_1,T_2:X\to P(X)$ two multivalued operators. Determine the metric conditions which imply that (T_1,T_2) is a weakly Picard pair of multivalued operators and T_1, T_2 are weakly Picard multivalued operators.

On Multi-Valued Weakly Picard Operators in Hausdorff Metric-Like Spaces

International Journal of Analysis and Applications, 2016
In this paper, we study multi-valued weakly Picard operators on Hausdorff metric-like spaces. Our results generalize some recent results and extend several theorems in the literature. Some examples are presented making effective our results.
