Some fixed point theorems for (CAB)-contractive mappings and related results [PDF]

Mathematica Moravica, 2015
In this paper, we introduced the concept of (CAB)-contractive mappings and provide sufficient conditions for the existence and uniqueness of a fixed point for such class of generalized nonlinear contractive mappings in metric spaces and several ...

Binary programs for asymmetric betweenness problems and relations to the quadratic linear ordering problem

EURO Journal on Computational Optimization, 2023
We present and compare novel binary programs for linear ordering problems that involve the notion of asymmetric betweenness and expose relations to the quadratic linear ordering problem and its linearization.

Leveraging Transfer Learning to Overcome Data Limitations in Czochralski Crystal Growth

Advanced Theory and Simulations, EarlyView.
A data‐driven framework combining Computational Fluid Dynamics (CFD) simulations and machine learning is proposed to model and optimize Czochralski crystal growth. Using different transfer learning strategies (Warm Start, Merged Training, and Hyperparameter Transfer) the study demonstrates improved predictions for Ge and GaAs growth from Si‐trained ...

Binary relations applied to the fuzzy substructures of quantales under rough environment

Demonstratio Mathematica
Binary relations (BIRs) have many applications in computer science, graph theory, and rough set theory. This study discusses the combination of BIRs, fuzzy substructures of quantale, and rough fuzzy sets.

Neutrosophic Hypercompositional Structures defined by Binary Relations [PDF]

Neutrosophic Sets and Systems, 2014
The objective of this paper is to study neutrosophic hypercompositional structures arising from the hypercompositions derived from the binary relations on a neutrosophic set.

A Quick Algorithm for Binary Discernibility Matrix Simplification using Deterministic Finite Automata

Information, 2018
The binary discernibility matrix, originally introduced by Felix and Ushio, is a binary matrix representation for storing discernible attributes that can distinguish different objects in decision systems. It is an effective approach for feature selection,

Operations on binary relations and their applications [PDF]

Bulletin of the American Mathematical Society, 1964
This paper is a rapid report from the author and the results are given without proofs. The author defines types of relations by means of semi-closure operations and discusses the existence of the smallest relation of a given type. By providing semi-closure operations with the condition ``join conservative'', a method of construction of the smallest ...

Topology Augmented with Geometry in the Assembly of Structural Databases: Kagome Intermetallics

Advanced Science, EarlyView.
The combination of topological filtering with geometrical restraints reliably screens for kagome layers within intermetallic compounds. The resulting comprehensive list of kagome net‐containing intermetallics can be reviewed to identify examples of interest for particular investigations and also used to build ML models to guide the search for further ...

Aging and the Spectral Properties of Brain Hemodynamics

Advanced Science, EarlyView.
As the brain ages, its metabolic demands decline—but not uniformly. Here, spectral slope flattening of resting‐state fMRI signals is proposed as a potential biomarker of pathologic brain aging. A subset of older adults diverges from youthful spectral and metabolic patterns, with changes linked to frontal white matter pathology and regional loss of ...
