Influence of hospital size on antimicrobial resistance and advantages of restricting antimicrobial use based on cumulative antibiograms in dogs with Staphylococcus pseudintermedius infections in Japan

open access: yesVeterinary Dermatology, Volume 32, Issue 6, Page 668-e178, December 2021., 2021
Background Antimicrobial resistance in Staphylococcus pseudintermedius (SP) and the prevalence of meticillin‐resistant SP (MRSP) is increasing in dogs worldwide. Objectives To evaluate the influence of hospital size on antimicrobial resistance of SP and whether restricted use of antimicrobials based on antibiograms could reduce the identification of ...

Bifurcations and exact traveling wave solutions for the regularized Schamel equation

open access: yesOpen Mathematics, 2021
In the present paper, we focus on studying the bifurcations and the traveling wave solutions (TWSs) for the regularized Schamel equation. Based on the bifurcation method of a dynamical system, a complete phase portrait analysis is given in various ...

Higher‐order Melnikov functions for single‐DOF mechanical oscillators: theoretical treatment and applications

open access: yesMathematical Problems in Engineering, Volume 2004, Issue 2, Page 145-168, 2004., 2004
A Melnikov analysis of single‐degree‐of‐freedom (DOF) oscillators is performed by taking into account the first (classical) and higher‐order Melnikov functions, by considering Poincaré sections nonorthogonal to the flux, and by explicitly determining both the distance between perturbed and unperturbed manifolds (“one‐half” Melnikov functions) and the ...

Existence and Nonexistence of Periodic Solutions for a Class of Fourth‐Order Partial Difference Equations

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
In this paper, we investigate multiplicity, existence, and nonexistence of periodic solutions to a fourth‐order partial difference equation via linking theorem and saddle point theorem. Our obtained results significantly generalize and improve some existing ones.
