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 ...

Ger‐type and Hyers‐Ulam stabilities for the first‐order linear differential operators of entire functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 22, Page 1151-1158, 2004., 2004
Let h be an entire function and Th a differential operator defined by Thf = f′ + hf. We show that Th has the Hyers‐Ulam stability if and only if h is a nonzero constant. We also consider Ger‐type stability problem for |1 − f′/hf| ≤ ϵ.

Global stability of a distributed delayed viral model with general incidence rate

open access: yesOpen Mathematics, 2018
In this paper, we discussed a infinitely distributed delayed viral infection model with nonlinear immune response and general incidence rate. We proved the existence and uniqueness of the equilibria.

Periodic solutions for some partial functional differential equations

open access: yesInternational Journal of Stochastic Analysis, Volume 2004, Issue 1, Page 9-18, 2004., 2004
We study the existence of a periodic solution for some partial functional differential equations. We assume that the linear part is nondensely defined and satisfies the Hille‐Yosida condition. In the nonhomogeneous linear case, we prove the existence of a periodic solution under the existence of a bounded solution.

Uniform practical stability in terms of two measures with effect of delay at the time of impulses

open access: yesNonlinear Engineering, 2016
In this paper, some sufficient conditions for uniform practical stability of impulsive functional differential equations in terms of two measures with effect of delay at the time of impulses are obtained by using piecewise continuous Lyapunov functions ...

Stability and stabilizability of dynamical systems with multiple time‐varying delays: delay‐dependent criteria

open access: yesMathematical Problems in Engineering, Volume 2003, Issue 4, Page 137-152, 2003., 2003
This paper deals with the class of uncertain systems with multiple time delays. The stability and stabilizability of this class of systems are considered. Their robustness are also studied when the norm‐bounded uncertainties are considered. Linear matrix inequality (LMIs) delay‐dependent sufficient conditions for both stability and stabilizability and ...

On the Lyapunov equation in Banach spaces and applications to control problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 29, Issue 3, Page 155-166, 2002., 2002
By extending the Lyapunov equation A*Q + QA = −P to an arbitrary infinite‐dimensional Banach space, we give stability conditions for a class of linear differential systems. Relationship between stabilizability and exact null‐controllability is established.

Investigation of interval stability of linear systems of neutral type of Lyapunov function method

open access: yesInternational Journal of Stochastic Analysis, Volume 15, Issue 1, Page 71-81, 2002., 2002
Systems of differential equations with deviating argument of neutral type [1, 3, 8] are used. The mathematical model takes into account not only the previous moments of time, but also the speed of their change. These equations more adequately describe the dynamics of processes, but their investigation faces significant difficulties.
