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.

Topological Entropy of Cournot-Puu Duopoly

Discrete Dynamics in Nature and Society, 2010
The aim of this paper is to analyze a classical duopoly model introduced by Tönu Puu in 1991. For that, we compute the topological entropy of the model and characterize those parameter values with positive entropy.

A Method for Ordering of LR-Type Fuzzy Numbers: An Important Decision Criteria

Axioms, 2016
Methods for ordering fuzzy numbers play an important role as decision criteria, with applications in areas such as optimization and data mining, among others. Although there are several proposals for ordering methods in the fuzzy literature, many of them

Quantitative System Risk Assessment From Incomplete Data With Belief Networks and Pairwise Comparison Elicitation

Risk Analysis, Volume 45, Issue 11, Page 4014-4038, November 2025.
ABSTRACT A method for conducting Bayesian elicitation and learning in risk assessment is presented. It assumes that the risk process can be described as a fault tree. This is viewed as a belief network, for which prior distributions on primary event probabilities are elicited by means of a pairwise comparison approach.

Describing the Dynamics and Complexity of Matsumoto-Nonaka's Duopoly Model

Abstract and Applied Analysis, 2013
We study the duopoly model proposed by Matsumoto and Nonaka (2006), in which two firms produce two complementary goods, and there are externalities of different signs.

On a Variational Method for Stiff Differential Equations Arising from Chemistry Kinetics

Mathematics, 2019
For the approximation of stiff systems of ODEs arising from chemistry kinetics, implicit integrators emerge as good candidates. This paper proposes a variational approach for this type of systems.

Long‐term prognostic implications of type 2 diabetes mellitus in colorectal cancer patients

Colorectal Disease, Volume 27, Issue 10, October 2025.
Abstract Aim Colorectal cancer (CRC) is one of the most prevalent cancers worldwide. Epidemiological evidence has identified Type 2 Diabetes Mellitus (T2DM) as a risk factor for CRC. This study aimed to evaluate the impact of T2DM, along with clinicopathological and socio‐demographic factors, on long‐term overall survival in a large, nationally ...
