In order to study the static mechanical relationship between rock-concrete assemblies and their components, the stress-strain characteristics, peak stress, strain and compression damage energy evolution laws of rock, concrete and rock-concrete assemblies were analysed by indoor uniaxial compression tests. The results show that the stress-strain curves of different rock-concrete composites are similar in uniaxial compression, their peak strengths and moduli of elasticity reside between the two components, which are greatly affected by the uniaxial compressive strength and modulus of elasticity of concrete, and their peak strains are enhanced significantly compared with those between the components.............

The rapid development of 5G New Radio (NR) and millimeter-wave (mmWave) communication systems highlights the critical importance of maintaining accurate phase synchronization to ensure reliable and efficient communication. This study focuses on evaluating phase noise models and implementing Minimum Mean Square Error (MMSE) algorithms for Common Phase Error (CPE) compensation. Through extensive simulations, we demonstrate that CPE compensation significantly enhances signal quality by reducing Error Vector Magnitude (EVM) and Bit Error Rate (BER) across various Signal-to-Noise Ratio (SNR) levels and antenna configurations. Results indicate that implementing MMSE-based CPE estimation and compensation.........

The Mn2+ doped LiAl5O8 single crystals' crystal field parameters and zero-field splitting parameter are theoretically determined utilizing the perturbation theory and the superposition model. The experimental value and the theoretical zero-field splitting parameter D are in good agreement. This establishes the experimental outcome that Mn2+ ions substitute at Li+ site in LiAl5O8 single crystal. The optical spectra of Mn2+ doped LiAl5O8 crystal are computed using the crystal field parameters and the crystal field analysis computer program. The computed and empirical energy values match reasonably well. Hence the theoretical study backs the experimental one.
