Summary: The September 2022 Ms 6.8 Luding earthquake provided valuable insights into the seismogenic environment, rupture dynamics, and seismic hazard of the Moxi fault after a seismic calm of more than 230 years. Through various data sources, including teleseismic body waves, regional strong-motion observations, GNSS, and InSAR data, researchers were able to analyze the spatiotemporal rupture evolution of the mainshock. The results suggest that the Moxi fault has the potential for future magnitude 7+ earthquakes, although geodetic prediction may overestimate the actual seismic moment released by the earthquake.

Summary: This article proposes a new H-bridge structured bipolar pulsewidth modulation (PWM) buck-boost ac-ac converter based on the nondifferential ac choppers. The converter can generate identical noninverting and inverting buck-boost voltage outputs using single control duty ratio, and also provides flexible operations using two control duty ratios. The use of nondifferential ac choppers eliminates complementary switching and inductor open-circuit issue.

Summary: This article proposes a solution to the cooperative fault-tolerant control problem for networks of stochastic nonlinear systems with actuator faults and input saturation. Fuzzy neural networks are used to estimate unknown functions and stochastic disturbance terms, while a smooth nonlinear function is constructed to estimate the saturation function. A novel adaptive fault-tolerant control protocol is proposed using backstepping design technique, and the stochastic Lyapunov functional strategy is used to prove convergence and boundedness of the closed-loop systems.

Summary: This study aimed to validate internal and external load metrics in NCAA D1 women's beach volleyball. The results showed that session rating of perceived exertion (sRPE) Load can be a valid alternative to internal load metrics, and distance covered should be considered in periodizing and monitoring training loads.

Summary: With a levitodynamics experiment in the strong and coherent quantum optomechanical coupling regime, the oscillator demonstrates its role as a broadband quantum spectrum analyzer. The asymmetry in the displacement spectrum between positive and negative frequency branches reveals the spectral features of the cavity field's quantum fluctuations, enabling exploration across a wide range of frequencies. Additionally, the quantum backaction generated by such vacuum fluctuations is significantly suppressed in a narrow spectral region due to destructive interference in the overall susceptibility.

Summary: Despite differences in methodology and specific results, studies using the same framework found that only a low to moderate proportion of mobility in older adults could be explained. More research is needed to improve our understanding of mobility determinants in this population.

Summary: The study reveals that the Ordos block exhibits rigid motion with negligible anticlockwise rotation; there is no significant differential motion and strain within the block, but it is influenced by adjacent blocks moving in different directions at different rates; deformation caused by adjacent blocks mainly occurs along the boundaries of grabens and fold-thrust fault zones.

Summary: The study utilized InSAR technique to assess the VLM at tide gauges in Korea, revealing overall stability with the largest VLM observed at the Pohang tide gauge station. Higher rates of uplift were observed along the coast of the Yellow Sea, while higher rates of subsidence were observed at Jeju and Seogwipo tide gauges. The approach provides unprecedented spatial and temporal resolution for estimating VLM rates at selected tide gauges when in-situ and GNSS observations are not available.

Summary: Research in multiple sports has shown that an individual's acute:chronic workload ratio (ACWR) correlates with injury. However, tailoring team trainings to each individual's ACWR is technically challenging and has not been found to decrease injury risk. In a National Collegiate Athletic Association (NCAA) men's soccer team, the average ACWR of the team was assessed to determine its correlation with injuries sustained throughout the season.

Summary: Using seismic and geodetic data, the detailed rupture characteristics of the 2021 M-w 7.4 Maduo earthquake were investigated. The results revealed that this earthquake was a supershear event, rupturing bilaterally along a 170 km fault segment. Furthermore, it was found that supershear earthquakes with simpler fault geometries have significantly smaller radiated energies.
