Summary: This paper proposes a calculation method using a cross-sectional vibration mode in combination with the impact-echo method to detect the health of concrete columns. It studies the variation of the predominant frequency in the mid-column region and the critical boundary and analyzes the influence of the edge on the detection results. The differences in eigenvalues under different cross-section vibration modes are revealed, and a quantitative method for evaluating concrete health using the impact-echo method is established. Through field tests and finite element simulation calculations, it is verified that the eigenvalues in the fixed mode are consistent with the predominant frequency measured near the edge region, overcoming the inaccuracy issue of the impact-echo method in detecting the edge area of concrete members. The impact-echo method can be better utilized for non-destructive testing of concrete members.

Summary: In recent years, there has been an increasing research interest in the rotational Doppler effect associated with the orbital angular momentum of light, which has emerged as a powerful tool for detecting rotating bodies in remote sensing. However, in realistic environments with turbulence, this method faces severe limitations as the rotational Doppler signals become unrecognizable amidst background noise. In this study, we propose a concise and efficient method using cylindrical vector beams that enables turbulence-resilient detection of the rotational Doppler effect. By employing a polarization-encoded dual-channel detection system, low-frequency noise caused by turbulence can be individually extracted and subtracted, mitigating the impact of turbulence. Proof-of-principle experiments demonstrate the feasibility of using this scheme to detect rotating bodies in non-laboratory conditions.

Summary: This paper investigates the adsorption and sensing properties of transition metal-doped WSSe gas-sensitive devices towards H2, CO, and CO2 gases related to thermal runaway in Li-ion batteries using density functional theory. The results show that Ti, Mn, and Mo dopants preferentially bind to the S-surface of the WSSe monolayer, and all three monolayers exhibit significantly improved sensing characteristics, with chemisorption towards CO. Band structure analysis suggests that the Ti-WSSe monolayer has the potential to be used as a resistive CO detection sensor. Recovery time calculations indicate the reuse capabilities of the gas-sensitive devices. Mn-WSSe monolayer shows potential for H2 detection, while Mo-WSSe monolayer is more suitable for CO2 detection. This work lays the foundation for potential gas-sensitive applications of WSSe monolayer in thermal runaway scenarios, advancing research in gas sensing domains.

Summary: This paper investigates the effects of electric and magnetic fields on the Goos-Hanchen (GH) shift in a semi-Dirac system. The results show that the magnitude and direction of the GH shift depend on various factors such as incidence angle, electric barrier height and width, and magnetic field. It is observed that there is a saltus step in GH shifts at the critical magnetic field, which decreases with increased potential barrier thickness. Additionally, the GH shift can be significantly enhanced by applying an electric field in the III region. These findings are important for the development of semi-Dirac based electronic devices.

Summary: Using full electron-phonon interactions and the Boltzmann transport equation, this study investigates the phonon scattering channel and electrical properties of graphene under anharmonic phonon renormalization (APRN). The results show that the APRN reduces the phonon frequency and three-phonon phase space with increasing temperature, affecting the acoustic branch more than the optical branch. The thermal conductivity of graphene decreases after considering three- and four-phonon scattering, and the primary scattering channels are identified. Furthermore, the APRN increases the strength of electron-phonon coupling and leads to an increase in n-type electric resistance at room temperature.
