Pullback attractors to impulsive evolution processes: Applications to differential equations and tube conditions

open access: yes, 2020
We define the notions of impulsive evolution processes and their pullback attractors, and exhibit conditions under which a given impulsive evolution process has a pullback attractor.

Linear Multistep Methods for Impulsive Differential Equations

open access: yesDiscrete Dynamics in Nature and Society, 2012
This paper deals with the convergence and stability of linear multistep methods for impulsive differential equations. Numerical experiments demonstrate that both the mid-point rule and two-step BDF method are of order p=0 when applied to impulsive ...

Depression, Anxiety and Criminal Behaviour Between Ages 32 and 48: A Propensity Score Matching Analysis From the Cambridge Study in Delinquent Development

open access: yesCriminal Behaviour and Mental Health, EarlyView.
ABSTRACT Background Depression, anxiety and criminal behaviour are often correlated, but the direction and nature of these associations remain contested. Aims To investigate the temporal relationships between depression and/or anxiety and criminal behaviour at age 32 and depression and/or anxiety and criminal behaviour at age 48.

Mechanochemical Amidation Mediated by 1,1’‐Oxalyldiimidazole for the Synthesis of Agrochemicals

open access: yesChemistry – A European Journal, EarlyView.
Mechanochemical amidation using 1,1'‐oxalyldiimidazole (ODI) overcomes limitations of 1,1’‐carbonyl diimidazole (CDI) as coupling agent by enabling the efficient mechanochemical synthesis of three marketed agrochemicals from deactivated carboxylic acids.

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes

open access: yesChemie Ingenieur Technik, EarlyView.
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

Stochastics integral equations with respect to semimartingales [PDF]

open access: yes
Stochastic integral equations were first developed by mathematicians as a tool for the explicit construction of the paths of diffusion processes for given coefficients of drift and diffusion. Since many physical, engineering, biological as well as social

Almost periodic solutions of impulsive differential equations

open access: yes, 2012
Impulsive differential equations are suitable for the mathematical simulation of evolutionary processes in which the parameters undergo relatively long periods of smooth variation followed by short-term rapid changes (that is, jumps) in their values ...
