High quality of service (QoS) requirements in multi-priority wireless sensor networks pose new challenges to the Internet of Things (IoT). In a multi-event wireless sensor network (MWSN), nodes generate different types of data packets with different priority such as urgent (high priority) or normal (low priority), with different traffic proportion.

In comparison to the vapour gas-compression refrigeration, magnetic heat-pumping near room-temperature is regarded to be an alternative technology due to its high energy efficiency and environmentally friendly solid-state cooling materials. The magnetic heat pump technology utilizes the magnetic field induced temperature change, which is based on the magnetocaloric effect (MCE).

This paper examines the role of bank credit to the private sector and private-sector investment in the transition to a low-carbon economy in Vietnam regarding other macroeconomic factors, such as GDP growth rate and electricity consumption from renewable energy. From 1986 to 2021, chronological classification was used. Through the ARDL regression model, the experimental results show that in the short term, credit to the private sector and private-sector investment initially help the economic transition to be effective.

µ −e conversion in a model of electroweak scale right-handed neutrino mass. We perform a detailed analysis of the µ − e conversion within an extended version of the standard model (SM) with mirror symmetry and low energy of the electroweak scale of the type I seesaw neutrino mass generation. After a brief introduction to the model, we derive the µ − e conversing ratio at one-loop approximation, in which the running inside are W gauge boson or singly charged scalars accompanying with neutrinos, and neutral scalars with new leptons.

The electronic states of FeSin −/0/+ (n = 1-2) clusters have been investigated with DFT, CASPT2, and DMRGCASPT2 methods. By using relatively large active spaces, the DMRG-CASPT2 method is found to provide highly accurate relative energies for the various relevant electronic states. Leading configurations, bond distances, harmonic vibrational frequencies, and relative energies for the low-lying states of the title clusters are reported.

This paper aims to propose financial solutions to support Vietnam in making the transition to a low-carbon economy as committed at COP 26 - 2021. By using statistical methods and analyzing secondary financial data, the author has indicated three financial challenges that Vietnam is facing, which are: (i) the lack of public investment capital in the transition fossil energy to renewable energy; (ii) the immaturity of the green financial Market; and (iii) the paucity of foreign green investment capital sources.

The objective of the study is to assess the impact of FDI on renewable energy use in Vietnam. Research results confirm that FDI projects with low technology and high energy consumption do not have a good impact on the economy in general and the use of renewable energy in particular. The study also confirms that economic growth and the development of financial markets have a very positive impact on renewable energy consumption. Finally, the study also suggests some policy implications for Vietnam in the case of increasing renewable energy use and sustainable development in the future.
