Current‐Induced Reversible Split of Elliptically Distorted Skyrmions in Geometrically Confined Fe3Sn2 Nanotrack

Advanced Science, 2023
Skyrmions are swirling spin textures with topological characters promising for future spintronic applications. Skyrmionic devices typically rely on the electrical manipulation of skyrmions with a circular shape.

Charming e-cigarette users with distorted science: a survey examining social media platform use, nicotine-related misinformation and attitudes towards the tobacco industry

BMJ Open, 2022
Objective To examine the role of social media in promoting recall and belief of distorted science about nicotine and COVID-19 and whether recall and belief predict tobacco industry beliefs.Design Young adults aged 18–34 years (N=1225) were surveyed cross-

Current-Based Coordination of Distributed Energy Resources in a Grid-Connected Low-Voltage Microgrid: An Experimental Validation of Adverse Operational Scenarios

Energies, 2022
Low-voltage grid-connected microgrids rely on the exploitation of inverter-interfaced distributed energy resources (DERs) in order to feed loads and to achieve bidirectional power flow controllability at their point of common coupling (PCC) with the ...

Harmonic Voltage Synchronization Using GPS Modules for Grid-Connected Power Converters

IEEE Open Journal of Power Electronics, 2022
Voltage-controlled inverters (VCI) for distributed energy resources allow operation in grid-connected and islanded conditions. Common techniques based on $P$-$f$, $Q$-$V$ droop-control use sinusoidal voltage references for the VCIs, which brings unwanted

Distorted Modeling of Density Currents

Coastal Engineering 1972, 1972
The paper describes a method of choosing scales for the correct representation of convective spread in a hydraulic model involving densimetric phenomena. Although most prototype spreads are non-viscous in nature it is possible for small scale laboratory spreads to become affected by viscous influence when the spreading density front is remote from the ...

Persistent currents in distorted quantum ring

Journal of Physics: Conference Series, 2008
Persistent currents in distorted narrow mesoscopic rings threaded by the magnetic flux of the Aharonow Bohm type are investigated. It is shown that the ring distortions can be modelled by an appropriate potential term. The cases with a single and multiple distortions are considered. The single distortion opens a gap in the electron energy spectrum of a

Calibration of Current Transformers in distorted conditions

Journal of Physics: Conference Series, 2018
In the context of modern power systems, where there are lots of non-linear loads and generators based on switching power electronics, the accurate measurement of voltage and current harmonics is a key task for the knowledge of the actual state of the network.

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
