On Generalized Avicenna Numbers
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT Avicenna numbers that we define in this paper, are a class of figurate numbers, including icosahedral, octahedral, tetrahedral, dodecahedral, rhombicosidodecahedral numbers and cubes, play a key role in mathematics, physics and various scientific fields.

Pythagorean fuzzy deductive system of BCL-algebra [version 1; peer review: 2 approved]
F1000ResearchBackground The deductive system of BCL-algebra has not been thoroughly explored, and its fuzzification remains undefined. This study aims to the association of this gap by introducing a fuzzy extension of the deductive system of BCL-algebra using ...

Squared cycles in monomial relations algebras
Central European Journal of Mathematics, 2006 Let \(\mathbb{K}\) be an algebraically closed field. Consider a finite dimensional monomial relations algebra \(\Lambda = {{\mathbb{K}\Gamma } \mathord{\left/ {\vphantom {{\mathbb{K}\Gamma } I}} \right. \kern-\nulldelimiterspace} I}\) of finite global dimension, where Γ is a quiver and I an admissible ideal generated by a set of paths from the path ...

Scenario‐free robust optimization algorithm for IMRT and IMPT treatment planning
Medical Physics, EarlyView.Abstract Background Robust treatment planning algorithms for intensity modulated proton therapy (IMPT) and intensity modulated radiation therapy (IMRT) allow for uncertainty reduction in the delivered dose distributions through explicit inclusion of error scenarios.

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Concrete materials consist of multiple phases with distinct mechanical properties, making it essential to accurately identify the mechanical behavior of both constituent phases and their interfaces for effective multiscale modeling. This study estimates the elastic properties of the interfacial transition zone using a machine learning (ML ...

Adaptive sampling for ecological monitoring using biased data: a stratum‐based approach
Oikos, EarlyView.Indicators of biodiversity change across large extents of geographic, temporal and taxonomic space are frequent products of various types of ecological monitoring and other data collection efforts. Unfortunately, many such indicators are based on data that are highly unlikely to be representative of the intended statistical populations.

Quantifying community keystoneness in metacommunities under disturbance
Oikos, EarlyView.Understanding how metacommunities respond to natural and anthropogenic disturbances is a key objective in ecology. In this study, we introduce an analytical framework to identify communities whose extirpation triggers stronger (hereafter keystone communities) or weaker (hereafter idle communities) cascading effects on extinction and colonization events

Polymer Composites, EarlyView.Mathematical Modeling of the Effect of Carbon Nanotubes on the Cure Behavior of a Carbon/Epoxy Prepreg Syste. ABSTRACT Carbon/Epoxy composite materials are used in a wide range of applications due to their superior performance. However, their properties are strongly related to cross‐linking reactions occurring during the curing process, and a prior ...
