Dynamics and control of fast ion crystal splitting in segmented Paul traps

, 2014
We theoretically investigate the process of splitting two-ion crystals in segmented Paul traps, i.e. the structural transition from two ions confined in a common well to ions confined in separate wells.

Leading-Following Consensus for Multi-Agent Systems With Event-Triggered Delayed Impulsive Control

IEEE Access, 2019
In this paper, the exponential leader-following consensus problem is investigated for networked multi-agent systems. In order to further reduce the usage of the communication resources, event-triggered delayed impulsive control strategy is put forward ...

Neural-Impulsive Pinning Control for Complex Networks Based on V-Stability

Mathematics, 2020
In this work, a neural impulsive pinning controller for a twenty-node dynamical discrete complex network is presented. The node dynamics of the network are all different types of discrete versions of chaotic attractors of three dimensions.

Impulsive Control of Systems with Network Structure Describing Spread of Political Influence [PDF]

Известия Иркутского государственного университета: Серия "Математика", 2018
We study a particular class of singular optimal control problems and corresponding impulsive control problems, which can be interpreted in terms of spread of a certain information impact (political influence) in a certain "social network'' represented by

Impulsivity and impulse control disorders in pregnancy [PDF]

Psychiatry and Clinical Psychopharmacology, 2017
OBJECTIVE: We investigate the relationship between impulsivity and impulse control disorders (ICDs) in pregnancy. We claim that women with unplanned pregnancies are more impulsive and have a higher frequency of ICDs. METHODS: We perform a study on the 152 pregnant women who applied to Haydarpaşa Numune Training and Research Hospital Obstetrics ...

Problematic Internet Use in Frontotemporal Dementia: A Case Series

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT The present study investigated problematic internet use (PIU) among 61 patients with frontotemporal dementia (FTD) compared to a cohort of 354 patients with mild cognitive impairment (MCI) and Alzheimer's dementia. PIU was identified in 22.9% of FTD patients compared to only 0.8% of AD patients (p < 0.001). Behaviors included compulsive social

Complex Behavior in a Fish Algae Consumption Model with Impulsive Control Strategy

Discrete Dynamics in Nature and Society, 2011
This paper investigates a dynamic mathematical model of fish algae consumption with an impulsive control strategy analytically. It is proved that the system has a globally asymptotically stable algae-eradication periodic solution and is permanent by ...

Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks

Advanced Materials, EarlyView.
ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...
