Fourth Toeplitz Determinants for Starlike Functions Defined by Using the Sine Function
In this article, we aim to study the upper bounds of the fourth Toeplitz determinant T42 for the function class Ss∗, which are connected with the sine function.

Group Differences of Multiregion Glutamate Concentration in Clinical High Risk and Schizophrenia
We investigated group effects of glutamate concentrations in 99 participants in four brain regions using proton magnetic resonance spectroscopy in clinical high risk, schizophrenia spectrum psychotic disorder individuals and healthy controls. Results showed no significant group differences, exploratory analyses showed significant positive symptom ...

Asymptotic Behaviors of Modified Block Toeplitz Determinant [PDF]
Some formulas are given for the asymptotic form of NXN modified block Toeplitz determinants for large N. These formulas are useful in obtaining the asymptotic behaviors of the correlation function of two spins of the Ising model on a two-dimensional regular lattice when the two spins are not on an axis.

ON THE INVERSE OF PATTERN MATRICES WITH APPLICATION TO STATISICAL MODELS
In this study the inverse of two patterned matrices has been investigated. First, for a Toeplitz-type matrix, it is proved that the exact number of independent cofactors is (n +2)/4 when n is even number and when n is an odd. Second, when the matrix is

Lattice Theory and Toeplitz Determinants [PDF]
This is a survey of our recent joint investigations of lattices that are generated by finite Abelian groups. In the case of cyclic groups, the volume of a fundamental domain of such a lattice is a perturbed Toeplitz determinant with a simple Fisher ...

A Riemann-Hilbert Approach to Asymptotic Analysis of Toeplitz+Hankel Determinants [PDF]
In this paper we will formulate 4×4 Riemann-Hilbert problems for Toeplitz+Hankel determinants and the associated system of orthogonal polynomials, when the Hankel symbol is supported on the unit circle and also when it is supported on an interval [a,b ...

Milk Yield and Composition Curves During the Postweaning Machine‐Milking Period in Red Deer Hinds
Deer milk is a dairy product valued for its unique composition and market potential. Research into deer lactation dynamics remains limited. In this study, 4,386 test‐day records from 170 red deer (Cervus elaphus L.) hinds in New Zealand were used to model the milk yield and composition curves using random regression models based on Legendre polynomials.

Mixture‐Based Estimation of Multivariate Data Hypervolume
ABSTRACT Estimating the hypervolume occupied by multivariate data is a fundamental problem in statistics and data science, with applications ranging from ecology and machine learning to multi‐objective optimization and Bayesian inference. Traditional approaches rely on geometric approximations, kernel density estimation, or convex‐hull constructions ...
