La aplicación física de la geometría astral como confirmación de la teoría kantiana del conocimiento

open access: yesLogos, 2007
The appearance of the non-Euclidean or astral geometries seemed to contradict the philosophy of the Kant´s mathematics. He had considered the possibility of a supreme geometry, but he discarded it due to it was not synthetically related with the ...

A look at non-Euclidean Geometries in Basic Education

open access: yesEducação Matemática Debate
The research presented in this article analyzed a teacher's reflective narrative on teaching non-Euclidean Geometries in Basic Education. Her experience is tied to her practice in schools, teacher education, and engagement with Mathematics Education ...

From Euclidean Geometry To Non-Euclidean Geometry, In Particular Hyperbolic Geometry, In Secondary Education Through Dynamic Geometry.

open access: yes, 2021
The current school requires teaching and learning about Euclidean and non-Euclidean geometry from the first educational levels. The research is carried out with the purpose of making a transition from Euclidean to non-Euclidean geometry, through ...

SpaMode: A Broadly Applicable Framework for Deciphering Spatial Multi‐Omics Using Multimodal Mixture of Disentangled Experts

open access: yesAdvanced Science, EarlyView.
SpaMode introduces a versatile framework for spatial multi‐omics integration across vertical, horizontal, and mosaic scenarios. By disentangling modality‐invariant and variant features through a mixture‐of‐experts mechanism, it adaptively reconfigures spatially heterogeneous signals.

Euclidean space perturbed by a constant vector field and its relation to a Zermelo navigation problem

open access: yesSelecciones Matemáticas
In this work, the authors perturb the Euclidean plane with a constant vector field of the form W = (0, ε) with 0 ≤ ε < 1, which can be interpreted as wind currents affecting the movement of ships in a constant unidirectional way.

Euclidean decompositions of hyperbolic manifolds and their duals

open access: yes, 2007
Epstein and Penner constructed in [EP88] the Euclidean decomposition of a non-compact hyperbolic n-manifold of finite volume for a choice of cusps, n >= 2. The manifold is cut along geodesic hyperplanes into hyperbolic ideal convex polyhedra.

Physics‐Constrained Constitutive Learning of Rate‐Limiting Timescales for Efficient Hydrogen‐Based Direct Reduction for Green Steel Making

open access: yesAdvanced Science, EarlyView.
A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

Cross-subject EEG emotion recognition using Riemannian Graph Transformers with Geodesic Adversarial Adaptation

open access: yesAlexandria Engineering Journal
Cross-subject electroencephalography (EEG) emotion recognition poses a fundamental challenge for brain-computer interfaces due to two factors: the non-Euclidean geometry of EEG spatial covariance matrices and the substantial inter-subject variability in ...

Swimming in Curved Surfaces and Gauss Curvature

open access: yesUniversitas Scientiarum, 2018
The Cartesian-Newtonian paradigm of mechanics establishes that, within an inertial frame, a body either remains at rest or moves uniformly on a line, unless a force acts externally upon it.

Physics‐Informed Machine Learning for Sustainable Alloy Design: Toward a Recyclable Unified Q&P Steel

open access: yesAdvanced Science, EarlyView.
A physics‐informed property‐bridging framework links high‐throughput hardness screening to tensile performance in quenching and partitioning steels. By transferring metallurgically guided representations across properties, a single alloy composition is designed to achieve multiple strength grades through heat‐treatment tuning alone, offering a ...
