Segmentation of scanning-transmission electron microscopy images using the ordered median problem
(Elsevier, 2022-01-15)
This paper presents new models for segmentation of 2D and 3D Scanning-Transmission Electron Micro- scope images based on the ordered median function. The main advantage of using this function is its good adaptability to ...

A review on differentiability and optimality conditions in fuzzy environments
(Springer, 2022-07-04)
In this paper we present a review of the most important notions and characterizations of differentiability and necessary optimality conditions for a fuzzy multiobjective problem. As basis of this review, we first study the ...

Two-phase strategies for the bi-objective minimum spanning tree problem
(Wiley, 2022-01-12)
This paper presents a new two-phase algorithm for the bi-objective minimum spanning tree (BMST) prob-lem. In the first phase, it computes the extreme supported efficient solutions resorting to both mathematicalprogramming ...

The Slashed Power Half-Normal Distribution with Applications
(MDPI, 2022)
In this paper, an extension of the power half-normal (PHN) distribution is introduced. This new model is built on the application of slash methodology for positive random variables. The result is a distribution with ...

The Extended Half-Skew Normal Distribution
(MDPI, 2022)
A new class of densities for modelling non-negative data, which is based on the skewsymmetric family of distributions proposed by Azzalini is introduced.We focus on the model generated by the skew-normal distribution, ...

Impact of Bullying—Victimization and Gender over Psychological Distress, Suicidal Ideation, and Family Functioning of Mexican Adolescents
(MDPI, 2022-05-19)
Bullying victimization is strongly associated with increased psychological distress and suicide in adolescents and poor family functioning. Knowledge of gender differences influencing these factors will improve the prevention ...

A mathematical programming approach to SVM-based classification with label noise
(ScienceDirect, 2022-08-30)
In this paper we propose novel methodologies to optimally construct Support Vector Machine-based classifiers that take into account that label noise occur in the training sample. We propose different alternatives based on ...

The tree based linear regression model for hierarchical categorical variables
(Elsevier, 2022-05-04)
Many real-life applications consider nominal categorical predictor variables that have a hierarchical structure, e.g. economic activity data in Official Statistics. In this paper, we focus on linear regression models built ...

REE Geochemistry of Neogene–Holocene Sediments of La Fontanilla Cove (Tinto Estuary, SW Spain)
(MDPI, 2022)
The Tinto and Odiel rivers (SW Spain) drain from a vast sulfide mining district and join at a 20-km-long estuary that enters the Atlantic Ocean. In this work, the contents of rare earth elements (REE) and fractionation ...
