On eigenvalue multiplicity and the girth of a graph [PDF]

open access: yes, 2011
Suppose that G is a connected graph of order n and girth g<n. Let k be the multiplicity of an eigenvalue μ of G. Sharp upper bounds for k are n-g+2 when μ∈{-1,0}, and n-g otherwise.

Towards a historical approach to physics education

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2021
Modern physics is a complex multiplicity of practices: theoretical, mathematical, experimental and simulation practices. Experimental and simulation practices are related to the pragmatic dimension of a physical theory. Mathematical practices are related

TELESCOPIC NUMERICAL SEMIGROUPS WITH MULTIPLICITY TEN AND EMBEDDING DIMENSION THREE

open access: yes, 2022
In this work, we give parametrizations of telescopic numerical semigroups with multiplicity ten and embedding dimension three. We also express some of its invariants in terms of generators of these semigroups such as the Frobenius number, genus and

Samples of geometric random variables with multiplicity constraints [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
We investigate the probability that a sample $\Gamma=(\Gamma_1,\Gamma_2,\ldots,\Gamma_n)$ of independent, identically distributed random variables with a geometric distribution has no elements occurring exactly $j$ times, where $j$ belongs to a specified

Gelfand Models for Diagram Algebras [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
A Gelfand model for a semisimple algebra $\mathsf{A}$ over $\mathbb{C}$ is a complex linear representation that contains each irreducible representation of $\mathsf{A}$ with multiplicity exactly one.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

The Qur'an and Mathematics: The Dimension of Tawhid and Knowledge in the Perspective of Afzalur Rahman

open access: yesQiST
The relationship between the Qur'an and mathematics remains theoretically contested between two dominant approaches: historical-empirical studies that attribute mathematical development in Islamic civilization to intercultural transmission, and ...

The Adaptive sampling revisited [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
The problem of estimating the number n of distinct keys of a large collection of N data is well known in computer science. A classical algorithm is the adaptive sampling (AS).
