Copolymer Synthesis of N‐Vinylacetamide and 2‐Methylene‐1,3‐Dioxepane Provides a New Degradable Polymer

Journal of Polymer Science, Volume 63, Issue 6, Page 1306-1318, 15 March 2025.
ABSTRACT N‐vinylamides, especially noncyclic N‐vinylacetamide (NVA), have been used in various applications such as biomaterials, surfactants, and hydrogels. However, their potential to copolymerize with cyclic ketene acetal (CKA) to create degradable polymers is underexplored.

Terahertz‐Induced Resistance Oscillations in MgZnO/ZnO Heterostructures

physica status solidi (b), EarlyView.
A theoretical work on the radiation‐induced magnetoresistance oscillations in MgZnO/ZnO heterostructures in the terahertz (THz) band is presented. It is demonstrated that photo‐oscillations are much better observed in that band. In fact, the large effective mass of electrons in this material makes terahertz the more suitable to be used.

Irradiated Coherent States in Magnetoresistance of 2D Electron Systems

physica status solidi (b), EarlyView.
A theoretical approach on the microwave‐induced resistance oscillations based on the coherent states of the quantum harmonic oscillator is reported. The coherent state expression for the quantum oscillator under a time‐dependent force is calculated. It is found that the principle of minimum uncertainty of coherent states, involving time and energy, is ...

Hybrid Block Censoring in Bathtub‐Shaped Lifetime Models and Their Optimal Censoring Strategies

Quality and Reliability Engineering International, EarlyView.
ABSTRACT In this research paper, we consider the lifetimes of engineering systems across different test conditions, using a two‐parameter bathtub‐shaped model to reflect varying risk levels. Both frequentist and Bayesian methods are proposed for estimating model parameters with an evaluation of their respective confidence intervals.

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

Advanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...
