NON-NULL CURVES OF TZITZEICA TYPE IN MINKOWSKI 3-SPACE [PDF]

Romanian Journal of Mathematics and Computer Science, 2014
In this paper, we study non-null curves of Tzitzeica type in Minkowski 3-space E_1^3 . We find a simple link between Tzitzeica curves and Rectifying curves in E_1^3.

Machine Learning‐Based Risk Stratification Tool for Hearing Loss in High‐Risk Neonates

The Laryngoscope, Volume 136, Issue 11, Page 4755-4764, November 2026.
Machine learning models, particularly XGBoost, provide robust risk stratification for neonatal hearing loss by capturing complex interactions among clinical risk factors such as NICU stay duration and family history. To translate these predictive capabilities into routine practice, an open‐access web‐based clinical decision support tool was developed ...

Unsupervised Patch‐Based Ecoregion Classification in Austria Using DEM‐Derived Features, Deep Learning, and Climate Data

Transactions in GIS, Volume 30, Issue 7, November 2026.
ABSTRACT Digital elevation models (DEMs) are widely used to characterize terrain and support applications ranging from geomorphology to environmental management. While traditional analyses rely on handcrafted geomorphometric features, advances in machine learning enable richer, data‐driven representations of topographic surfaces.

Osculating Mate of a Curve in Minkowski 3-Space

Axioms
In this paper, we introduce and develop the concept of osculating curve pairs in the three-dimensional Minkowski space. By defining a vector lying in the intersection of osculating planes of two non-lightlike curves, we characterize osculating mates ...

Foliation of null cones by surfaces of constant spacetime mean curvature near MOTS

Journal of the London Mathematical Society, Volume 114, Issue 5, November 2026.
Abstract Marginally outer trapped surfaces (MOTS) in spacetimes are well‐known to indicate the existence of black holes. Using flow techniques, we prove that a neighbourhood of a stable MOTS in a null cone may be foliated by hypersurfaces of constant spacetime mean curvature.

Detecting Anomalous Cell Behavior in Electrochemical Battery Testing Using Machine Learning

Advanced Engineering Materials, Volume 28, Issue 20, 21 October 2026.
Machine‐learning‐based screening enables automated identification of anomalous battery cells from complementary electrochemical tests. A curated battery database supports configuration‐aware comparison of rate‐capability and impedance data. Supervised classification of rate‐test data achieves 90% accuracy, while CNN‐VAE‐based impedance analysis reaches

Fractional Nikiforov‐Uvarov Formalism for Dunkl‐Schrödinger Equation With Deng‐Fan Molecular Model

International Journal of Quantum Chemistry, Volume 126, Issue 19, October 5, 2026.
The effect of Dunkl deformation parameters on energy eigenvalues of Deng‐Fan potential (DFP) is evaluated using conformable fractional Nikiforov‐Uvarov method. Our results show that energy eigenvalues of DFP for selected diatomic molecules are significantly influenced by the Dunkl deformation parameter, fractional parameter, kinetic pre‐factor and ...
