Complex Pearson Correlation Coefficient for EEG Connectivity Analysis [PDF]

open access: yesSensors, 2022
In the background of all human thinking—acting and reacting are sets of connections between different neurons or groups of neurons. We studied and evaluated these connections using electroencephalography (EEG) brain signals. In this paper, we propose the use of the complex Pearson correlation coefficient (CPCC), which provides information on ...

9j-coefficients and higher [PDF]

open access: yes, 2020
The su(2) 3j-coefficients (or 3j-symbols), 6j-coefficients, 9j-coefficients and higher (referred to as 3nj-coefficients) play a crucial role in various physical applications dealing with the quantization of angular momentum.

Spectra of Jacobi Operators via Connection Coefficient Matrices [PDF]

open access: yesCommunications in Mathematical Physics, 2021
AbstractWe address the computational spectral theory of Jacobi operators that are compact perturbations of the free Jacobi operator via the asymptotic properties of a connection coefficient matrix. In particular, for Jacobi operators that are finite-rank perturbations we show that the computation of the spectrum can be reduced to a polynomial root ...

The derivative connecting problems for some classical polynomials

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2019
Given two polynomial sets $\{ P_n(x) \}_{n\geq 0},$ and $\{ Q_n(x) \}_{n\geq 0}$ such that $$\deg ( P_n(x) ) =n, \deg ( Q_n(x) )=n.$$ The so-called the connecting problem between them asks to find the coefficients $\alpha_{n,k}$ in the expression ...

Geometric distribution series connected with certain subclasses of univalent functions [PDF]

open access: yesSurveys in Mathematics and its Applications, 2023
In this paper, we consider the class of normalized analytic functions of the form f(z)=z+∑n=2∞ anzn. Following this functions, we define the functions whose coefficients are probabilities of the geometric distribution series and other special modes of ...

On inversion and connection coefficients for basic hypergeometric polynomials [PDF]

open access: yes, 2015
In this paper, we propose a general method to express explicitly the inversion and the connection coefficients between two basic hypergeometric polynomial sets.

A recurrence formula for Jack connection coefficients

open access: yes, 2014
This article is devoted to the study of Jack connection coefficients, a generalization of the connection coefficients of the classical commutative subalgebras of the group algebra of the symmetric group closely related to the theory of Jack symmetric functions.

Regression Coefficient Derivation via Fractional Calculus Framework

open access: yesJournal of Mathematics, 2022
This study focuses on deriving coefficients of a simple linear regression model and a quadratic regression model using fractional calculus. The work has proven that there is a smooth connection between fractional operators and classical operators ...

Effect of Connection Resistance between Cyclones and Backpass on Furnace Solids Suspension Density Profile and Circulation Rates in CFB

open access: yesEnergies, 2021
The connection section between cyclones and backpass is an important configuration in multi-cyclone circulating fluidized bed boilers (CFB). In this work, the resistance coefficient of different connection modes, and connection resistance distribution ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
