Asymptotic properties of a stochastic nonautonomous competitive system with impulsive perturbations
Advances in Difference Equations, 2017 In this paper, a generalized nonautonomous stochastic competitive system with impulsive perturbations is studied. By the theories of impulsive differential equations and stochastic differential equations, we have established some asymptotic properties of

Advanced Intelligent Systems, EarlyView.Inspired by the Mexican jumping bean, this study presents a centimeter‐scale, electronics‐free robot that merges principles from both the animal and plant kingdoms. A thermo‐responsive actuator mimicking larval motion, enclosed within a uniquely shaped plant‐seed‐inspired shell, generates jumping, rolling, flipping, sliding, and climbing through ...

Continuous and Large‐Scale: ELEANOR, the Soft Architected Arm Inspired by the Elephant Trunk
Advanced Intelligent Systems, EarlyView.A large‐scale, architected continuum robot inspired by the macroscopic properties of the African elephant trunk achieves adaptive elephant‐like movements and whole‐body grasping. The results demonstrate that designing from the natural system’s macroscopic properties, rather than prescribing behaviors, provides a powerful strategy for developing ...

Practical Stability in terms of Two Measures for Impulsive Differential Equations with “Supremum”
International Journal of Differential Equations, 2011 The object of investigations is a system of impulsive differential equations with “supremum.” These equations are not widely studied yet, and at the same time they are adequate mathematical model of many real world processes in which the present state ...

Firearm carrying practices and motivations: A mixed methods study among adults and youth
American Journal of Community Psychology, EarlyView.Abstract The purpose of this participatory action, mixed methods research study was to identify motivations related to firearm carrying from a qualitative perspective, and then to use quantitative research to characterize the patterns of motivations around carrying.

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Tuberous sclerosis complex (TSC) is a genetic condition with multisystem neurocutaneous signs, including hamartomas, epilepsy, and neuropsychological difficulties. Although sleep disorders are increasingly recognized in TSC, they remain poorly described in adults.

Positive solutions of linear impulsive differential equations [PDF]
, 2005 The paper deals with the existence of positive (nonnegative) solutions of linear homogeneous impulsive differential equations. The main result is also applied to the investigation of a similar problem for higher-order linear homogeneous impulsive ...

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024
Australian Journal of Social Issues, EarlyView.ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

On delay differential equations with impulses
Journal of Mathematical Analysis and Applications, 1989 The authors' summary: Sufficient conditions are obtained respectively for the asymptotic stability of the trivial solution of \[ \dot x(t)+ax(t- \tau)=\sum^{\infty}_{j=1}b_ jx(t_ j-\tau)(t-t_ j),\quad t\neq t_ j, \] and for the existence of a nonoscillatory solution; conditions are also obtained for all solutions to be oscillatory.
