Measurement and analysis of magnetic properties of Fe-based amorphous materials under harmonic loading

AIP Advances
Amorphous materials exhibit significant potential for applications in energy-efficient distribution transformers and high-speed motors. In these contexts, the iron core typically operates not under ideal sinusoidal excitation, but under harmonic ...

From Adult to Adolescent: Alignment in Clinical Trials and Outcomes in Axial Spondyloarthritis

Arthritis Care &Research, EarlyView.
Spondyloarthritis (SpA) is a group of chronic inflammatory diseases encompassing axial and peripheral forms, with up to 20% of patients developing symptoms before age 16. Despite this substantial pediatric burden, treatment options for juvenile‐onset SpA (JSpA), particularly those with axial disease (axJSpA), remain limited.

Hybrid coherent control of magnons in a ferromagnetic phononic resonator excited by laser pulses

Physical Review Research
We propose and demonstrate the concept of hybrid coherent control (CC) whereby a quantum or classical harmonic oscillator is excited by two excitations: one is quasiharmonic (i.e., harmonic with a finite lifetime) and the other is a pulsed broadband ...

Incidence, Risk Factors and Management of Adverse Events in Contemporary Real‐World Care of Children with Juvenile Idiopathic Arthritis

Arthritis Care &Research, Accepted Article.
Objective We describe the frequency, risk factors, severity, and management of actionable and serious adverse events (AAE and SAE) in children with newly diagnosed Juvenile Idiopathic Arthritis (JIA) in Canada. Methods We enrolled patients within 3 months of JIA diagnosis in the Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) Registry,

Hysteresis characteristics influence on the super-harmonic vibration of a bi-stable piezoelectric energy harvester

Journal of Low Frequency Noise, Vibration and Active Control, 2018
The smart structures with the harmonic nonlinear vibration are used widely to broaden the frequency range of vibrations energy harvesting. However, it is presently considered that the smart materials have some hysteresis properties.

Research on the Orthogonal Fundamental Mode Fluxgate Sensor Circuit

IEEE Access, 2020
Currently, magnetic fluxgate circuits used for magnetic field measurements mostly adopt parallel excitation second harmonic generation. The magnetic fluxgate developed by this method cannot possess both low noise and high bandwidth at the same time.

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.
