Lectures mathématiques : sédimentation, réactivation ou partage ?
Methodos, 2020 Historians of mathematics have often noticed a singularity of their discipline: unlike physics, the history of mathematics does not proceed essentially by conjectures and refutations, but by a succession of reinterpretations of the past in order to ...

The Role of Infinity with Signs in Mathematics [PDF]
Education Journal, 2013 The article shows the significance of signs +∞ and -∞ (infinity with signs) for a full exposition of some of the problematic materials in mathematics. With its help smoothness of the curve, specified by functions with finite and infinite derivatives at the points, is determined. The properties of the function f, with which you can set the smoothness of

Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions
Advanced Functional Materials, EarlyView.Magnetic force microscopy operated under vacuum conditions enables the qualitative identification of higher‐order skyrmions and antiskyrmions in Co/Ni multilayers at room temperature. Distinct stray‐field contrast signatures arise from vertical Bloch lines and complex domain‐wall configurations.

Designing Asymmetric Memristive Behavior in Proton Mixed Conductors for Neuromorphic Applications
Advanced Functional Materials, EarlyView.Protonic devices that couple ionic and electronic transport are demonstrated as bioinspired neuromorphic elements. The devices exhibit rubber‐like asymmetric memristive behavior with slow voltage‐driven conductance increase and rapid relaxation, enabling simplified read–write operation.

Students’ Early Grade Understanding of the Equal Sign and Non-standard Equations in Jordan and India
International Journal of Research in Education and Science, 2018 Many students around the world are exposed to a rote teaching style in mathematics that emphasizes memorization of procedures. Students are frequently presented with standard types of equations in their textbooks, in which the equal sign is immediately ...

Nonlocal Kirchhoff superlinear equations with indefinite nonlinearity and lack of compactness
, 2019 We study the following Kirchhoff equation $$- \left(1 + b \int_{\mathbb{R}^3} |\nabla u|^2 dx \right) \Delta u + V(x) u = f(x,u), \ x \in \mathbb{R}^3.$$ A special feature of this paper is that the nonlinearity $f$ and the potential $V$ are indefinite ...

Advanced Functional Materials, EarlyView.This study presents a dynamic interaction between liquid resins and photopolymerized structures enabled by an in situ light‐writing setup. By controlling a three‐phase interface through localized photopolymerization, which provides physical confinement for the remaining uncured resin regions, the approach establishes a programmable pathway that ...
