Class performance: An empirical case of Chinese service workers in hair salons

open access: yesRegional Science Policy &Practice, Volume 15, Issue 9, Page 1926-1940, December 2023., 2023
Abstract China's service sector has attracted millions of internal migrants from impoverished rural areas. This research investigates how service work contributes to the reproduction of class inequalities in China through the everyday interactions between service workers and customers.

Tolerability and the effect on skin Staphylococcus pseudintermedius density of repeated diluted sodium hypochlorite (bleach) baths at 0.005% in healthy dogs

open access: yesVeterinary Dermatology, Volume 34, Issue 6, Page 489-494, December 2023., 2023
Background – Dilute sodium hypochlorite (bleach) baths at 0.005% concentration twice weekly have been shown to markedly reduce the severity of atopic dermatitis in children, yet no tolerability and efficacy data are available for this treatment in dogs.

Sensitivity of a Hymenoptera serological immunoglobulin (Ig)E assay for the diagnosis of venom hypersensitivity in dogs

open access: yesVeterinary Dermatology, Volume 34, Issue 6, Page 543-553, December 2023., 2023
Background – Hymenoptera envenomation with honey bee (Apis mellifera) and paper wasp (Polistes spp.) may cause life‐threatening anaphylaxis in dogs. In human patients, clinical history, intradermal testing (IDT) and measurement of allergen‐specific serological immunoglobulin (Ig)E (sIgE) are used to support a diagnosis of Hymenoptera venom ...

Two types of hypergeometric degenerate Cauchy numbers

open access: yesOpen Mathematics, 2020
In 1985, Howard introduced degenerate Cauchy polynomials together with degenerate Bernoulli polynomials. His degenerate Bernoulli polynomials have been studied by many authors, but his degenerate Cauchy polynomials have been forgotten.

Determinants of some Hessenberg matrices with generating functions

open access: yesSpecial Matrices, 2022
In this paper, we derive some relationships between the determinants of some special lower Hessenberg matrices whose entries are the terms of certain sequences and the generating functions of these sequences.

Matrix Manipulations for Properties of Pell p-Numbers and their Generalizations

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
In this paper, we define the Pell-Pell p-sequence and then we discuss the connection of the Pell-Pell p-sequence with Pell and Pell p-sequences. Also, we provide a new Binet formula and a new combinatorial representation of the Pell-Pell p-numbers by the

Disproving a conjecture of Thornton on Bohemian matrices

open access: yesOpen Mathematics, 2021
In this paper, we disprove a remaining conjecture about Bohemian matrices, in which the numbers of distinct determinants of a normalized Bohemian upper-Hessenberg matrix were conjectured.

Determinants of some special matrices over commutative finite chain rings

open access: yesSpecial Matrices, 2020
Circulant matrices over finite fields and over commutative finite chain rings have been of interest due to their nice algebraic structures and wide applications. In many cases, such matrices over rings have a closed connection with diagonal matrices over

Derivative and higher-order Cauchy integral formula of matrix functions

open access: yesOpen Mathematics, 2021
The derivative of a nn-order matrix function on the complex field is usually defined as a n2{n}^{2}-order matrix, which is not suitable for generalizing Cauchy integral formula of matrix functions to its higher-order derivative form. In this paper, a new

A trace bound for integer-diagonal positive semidefinite matrices

open access: yesSpecial Matrices, 2020
We prove that an n-by-n complex positive semidefinite matrix of rank r whose graph is connected, whose diagonal entries are integers, and whose non-zero off-diagonal entries have modulus at least one, has trace at least n + r − 1.
