Summary: Using the passive seismic standing waves method, a successful mapping of the Barsukovskaya karst cave in Novosibirsk, Russia was conducted. A map of the lowest mode frequency distribution over the cave roof was constructed through areal passive seismic survey, showing consistency with the cave diagram drawn up earlier by speleologists.

Summary: This paper studies the propagation of deformation waves in an underground gas pipeline and investigates vibration processes caused by various mechanical impacts. Results from experiments and numerical simulations provide insights for designing new automated monitoring systems. The information obtained allows for determining the monitoring system's structure, assessing sensor sensitivity, and verifying mathematical models describing vibration processes in gas pipelines.

Summary: This study presents the results of a geophysical survey conducted on the Sukhumi Lighthouse, which was built in 1861. The survey determined the stress-strain state, residual resource, tension of the fastening cables, fixation of piles in the ground (rigid/nonrigid), and immersion depth of the lighthouse. The passive seismic standing method and the tapping method were used to extract natural vibrations and record reflected seismic waves for analysis.

Summary: Developing a new method to identify and locate underground cavities is crucial for urban development and civil engineering. By detecting the Finite-interval Spectral Power of seismic ambient noise, it is possible to use single-station measurements to find the location of cavities on the Earth's free surface. This method has been tested in Hungary and is ready for further testing in various cavity conditions and applications.

Summary: Salt structures are commonly found in basins globally and have significant implications in understanding tectonic movements and hydrocarbon trapping. However, mapping these complex structures using seismic methods is challenging, especially when an evaporitic layer forms over salt. This study investigates the elastic properties of thin evaporitic caprocks through controlled experiments and field surveys, highlighting the importance of considering complex mode conversions on top of the salt in seismic velocity model building and imaging.

Summary: This study introduces probabilistic seismic demand and capacity models for underground structures, accounting for the spatial distribution characteristics of soil properties. These models are applied in a reliability analysis to estimate seismic fragility, considering epistemic uncertainties. The proposed models effectively capture the dependency between inter-story drift and peak ground velocity, providing a useful tool for assessing the seismic fragility of similar underground structures.

Summary: This study conducted a comparative experiment to discuss the detectability and influencing factors of heterogeneous stress field distributions in underground coal mines in North China. The results showed that curvature variations and mined-out voids are the dominant factors affecting the uneven distribution of stress fields in coal mine panels.

Summary: This paper proposes a new topology for the Einstein Telescope that separates key components and noise-inducing equipment into separate excavations, allowing continuous detection during maintenance and upgrades. The distribution of seismic attenuation chain components over multiple tunnel levels improves event detection efficiency and leaves room for future upgrades. The design also eliminates mechanical crowding around the test masses, reducing the need for support measures.

Summary: Underground mining engineering induces complex three-dimensional stress changes, disrupts the original stress balance, and causes deformation, fracturing, and ground subsidence. A large-scale three-dimensional physical similarity model was developed to study the mining process of coal seams, revealing evident fractured fields around the goaf. The research results can provide valuable references for the stability of deep underground projects such as coal mining, tunnel excavation, and nuclear waste storage.

Summary: This paper introduces the tensorial force acting in a localized seismic focus and the corresponding seismic waves. The far-field and near-field seismic waves have different amplitudes and decay characteristics, and methods for determining earthquake parameters from seismic wave measurements are discussed.

Summary: In this study, a gas-spring with adjustable nonlinear capacity is introduced into a conventional linear dynamic vibration absorber to form a nonlinear gas-spring dynamic vibration absorber for structural seismic response control. The mechanical properties of the symmetrical combined gas-spring system are studied through theoretical analysis and model tests. Shaking table tests are conducted to investigate the control effect and nonlinear damping mechanism of the gas-spring DVA, and a numerical model is established and validated by experimental results.

Summary: Machine learning-assisted modelling can improve the safe operation of deep geological repositories (DGR). In this study, a ML-assisted 3D heat transport model for a mock-up DGR tunnel was developed and validated with experimental data. The results demonstrate the effectiveness of ML in predicting temperature evolution and identifying faulty sensor data. Rating: 9/10

Summary: This paper presents a novel compact diplexer based on mixed-mode isosceles right triangular (IRT) substrate integrated waveguide (SIW) cavities. A dual-mode IRT SIW junction cavity is direct-coupled with two single-mode IRT SIW cavities for lower and upper channels, respectively. The diplexer has two third-order filtering channels, centered at 16 and 18.3 GHz with 400 and 422 MHz bandwidths. The in-band measured return and insertion losses are 19 dB/1.3 dB in the lower band and 17 dB/1.36 dB in the upper band. Due to the orthogonality of TE102 and TE201 modes in dual-mode IRT SIW cavity, high isolation (>45 dB) between two channels is obtained. Besides, the proposed diplexer based on the triangular SIW cavity also has advantages of low cost and easy integration with other planar circuits.
