Identificación de una Bifurcación de Hopf con o sin Parámetros
Revista de Ciencias, 2017 En este trabajo se presenta los lineamientos teóricos que identifica la existencia de una bifurcación genérica de Hopf, con o sin parámetros, a través de un punto o una línea de puntos de equilibrio para un sistema dinámico continúo.

Asymptotics for the Spectrum of the Laplacian in Thin Bars with Varying Cross Sections
Mathematical Methods in the Applied Sciences, Volume 49, Issue 8, Page 8044-8060, 30 May 2026.ABSTRACT We consider spectral problems for the Laplace operator in 3D rod structures with a small cross section of diameter O(ε)$$ O\left(\varepsilon \right) $$, ε$$ \varepsilon $$ being a positive parameter. The boundary conditions are Dirichlet (Neumann, respectively) on the bases of this structure, and Neumann on the lateral boundary.

Ewald's Conjecture and integer points in algebraic and symplectic toric geometry
Proceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.Abstract We solve several open problems concerning integer points of reflexive smooth polytopes, also known as monotone polytopes. While the paper belongs to the realm of discrete geometry, the connection with symplectic and algebraic geometry appears naturally since these polytopes have an important role in both areas.

International Journal of Imaging Systems and Technology, Volume 36, Issue 2, March 2026.ABSTRACT Radiomics, the practice of mining quantitative features from medical imaging, has gained increasing popularity in diagnosing and treating cancer. However, clinical deployment and adoption of radiomics tools in real‐world practice remain limited. To increase trust in radiomics models, one of the main remaining challenges is ensuring fairness by

Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Total Suspended Solids (TSS) significantly degrade water quality by reducing light penetration and oxygen availability, while facilitating the transport of toxic contaminants. Managing TSS in watersheds requires an understanding of both hydrological connectivity and pollutant dynamics; however, these efforts are significantly constrained by ...

A sufficiently complicated noded Schottky group of rank three
Cubo, 2020 In 1974, Marden proved the existence of non-classical Schottky groups by a theoretical and non-constructive argument. Explicit examples are only known in rank two; the first one by Yamamoto in 1991 and later by Williams in 2009.

Mixed‐Condorcet: An Advanced Method of Clustering for Mixed Data in Social Sciences
Computational and Mathematical Methods, Volume 2026, Issue 1, 2026.This paper provides a new clustering method for mixed data based on α‐Condorcet, denoted mixed‐Condorcet, by introducing a new Condorcet criterion. This criterion combines α‐Condorcet and k‐prototype criteria. Next, we give the within‐cluster sum‐of‐squares expression for our new method.

Distorted distributions and ROC curves
Scandinavian Journal of Statistics, Volume 52, Issue 4, Page 1786-1815, December 2025.Abstract We consider new distortion functions based on the receiver operating characteristic (ROC) and ordinal dominance (OD) curves. Various stochastic orders and aging properties are characterized by using the interpretation of ROC and OD distortions as cumulative distribution functions of suitable relative random variables.
