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 ...

miR‐34a is upregulated in AIP‐mutated somatotropinomas and promotes octreotide resistance

open access: yesInternational Journal of Cancer, Volume 147, Issue 12, Page 3523-3538, 15 December 2020., 2020
Abstract Pituitary adenomas (PAs) are intracranial tumors associated with significant morbidity due to hormonal dysregulation, mass effects and have a heavy treatment burden. Growth hormone (GH)‐secreting PAs (somatotropinomas) cause acromegaly‐gigantism.

Vector dissipativity theory for large‐scale impulsive dynamical systems

open access: yesMathematical Problems in Engineering, Volume 2004, Issue 3, Page 225-262, 2004., 2004
Modern complex large‐scale impulsive systems involve multiple modes of operation placing stringent demands on controller analysis of increasing complexity. In analyzing these large‐scale systems, it is often desirable to treat the overall impulsive system as a collection of interconnected impulsive subsystems.

Periodic boundary value problems for impulsive neutral differential equations with multi-deviation arguments [PDF]

open access: yes, 2010
We develop the impulsive inequality and the classical lower and upper solutions, and establish the comparison principles. By using these results and the monotone iterative technique, we obtain the existence of solutions of periodic boundary value ...

Robust dissipativity for uncertain impulsive dynamical systems

open access: yesMathematical Problems in Engineering, Volume 2003, Issue 3, Page 119-128, 2003., 2003
We discuss the robust dissipativity with respect to the quadratic supply rate for uncertain impulsive dynamical systems. By employing the Hamilton‐Jacobi inequality approach, some sufficient conditions of robust dissipativity for this kind of system are established.

A second‐order impulsive Cauchy problem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 31, Issue 8, Page 451-461, 2002., 2002
We study the existence of mild and classical solutions for an abstract second‐order impulsive Cauchy problem modeled in the form u¨(t)=A u(t)+f(t,u(t),u˙(t)),t∈(−T0,T1),t≠ti;u(0)=x0,u˙(0)=y0; △u(ti)=Ii1 (u (ti)). △u˙(ti)=Ii2 (u˙ (ti+)) where A is the infinitesimal generator of a strongly continuous cosine family of linear operators on a Banach space X ...

Impulsive functional‐differential equations with nonlocal conditions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 29, Issue 5, Page 251-256, 2002., 2002
The existence, uniqueness, and continuous dependence of a mild solution of an impulsive functional‐differential evolution nonlocal Cauchy problem in general Banach spaces are studied. Methods of fixed point theorems, of a C0 semigroup of operators and the Banach contraction theorem are applied.

On second order impulsive functional differential equations in Banach spaces

open access: yesInternational Journal of Stochastic Analysis, Volume 15, Issue 1, Page 45-52, 2002., 2002
In this paper, a fixed point theorem due to Schaefer is used to investigate the existence of solutions for second order impulsive functional differential equations in Banach spaces.

Nonoscillation of the solutions of impulsive differential equations of third order

open access: yesInternational Journal of Stochastic Analysis, Volume 14, Issue 3, Page 309-316, 2001., 2001
Necessary and sufficient conditions are found for existence of at least one bounded nonoscillatory solution of a class of impulsive differential equations of third order and fixed moments of impulse effect. Some asymptotic properties of the nonoscillating solutions are investigated.
