Model Based

The variational approach to the Glashow–Weinberg–Salam model, based on canonical quantization, is presented. It is shown that taking into consideration the Becchi–Rouet–Stora symmetry leads to the correct, temperature-dependent, effective potential. This generalization of the Weinberg–Coleman potential leads to a phase transition of the first kind.

Fabrication And Characterization

This article describes the fabrication and characterization of magnetic nanowires, focusing on the magnetic properties of patterned arrays of metallic magnetic nanowires electrodeposited into the pores of anodized-alumina membranes. It also discusses the complex magnetization processes, both in isolated nanowires and in collectively patterned arrays. After providing an overview of the state-of-the-art on fabrication techniques of nanowires, the article considers the microstructure of magnetic nanowires and the magnetic properties of single nanowires. It then examines the collective behavior of arrays where the interactions among the magnetic entities play an important role, along with the transport properties of magnetic nanowires, the temperature-dependent effects (such as magnetoelastic-induced anisotropy), and the dynamic properties of magnetization such as ferromagnetic resonance characteristics and spin-wave excitations in ferromagnetic nanowires. Finally, it presents an overview of future research directions.

This work presents an experimental and numerical study on the dynamic properties of viscoelastic (VE) microvibration damper under microvibration conditions at different frequencies and temperatures. The experimental results show that the storage modulus and the loss factor of VE microvibration damper both increase with increasing frequency but decrease with increasing temperature. To explicitly and accurately represent the temperature and frequency effects on the dynamic properties of VE microvibration damper, a modified standard solid model based on a phenomenological model and chain network model is proposed. A Gaussian chain spring and a temperature-dependent dashpot are employed to reflect the temperature effect in the model, and the frequency effect is considered with the nature of the standard solid model. Then, the proposed model is verified by comparing the numerical results with the experimental data. The results show that the proposed model can accurately describe the dynamic properties of VE microvibration damper at different temperatures and frequencies.
