Summary: The research on folds and folding is based on detailed geometrical analysis, and their relationships with structures such as fractures are significant for understanding stress, strain, kinematics, mechanics, and tectonic processes. The distinction between passive and active folding is important, with passive folding being easier to model and understand compared to active folding. Future research should focus on experimental and numerical modeling of active folds to further enhance our understanding of complex fold geometries observed in rocks.

Summary: This article uses an unproven geometry theorem to analyze the achievements, improvements, and limitations of GeoGebra and other computer algebra systems in dealing with geometric inequalities. By addressing variants of the theorem with different tools, new approaches and considerations are introduced for future improvements in automated reasoning in geometry algorithms. Additionally, an original result regarding inscribable triangles is obtained.

Summary: This study evaluated the effects of modeling uncertainties on kinematic simulations at small scale, developed a multibody model of a Messor barbarus ant, and acquired kinematic data using high-speed cameras. The results showed that the model was more sensitive to perturbations on marker position, which is of interest for locomotion studies of small quadrupeds and other multi-legged animals.

Summary: Coastal hydro-morphodynamics present significant uncertainties, with a need to explicitly include error levels in the analysis. Outdated topo-bathymetry data can lead to uncertainties and impact decision-making outcomes.

Summary: This paper presents a distributed cooperative surrounding control method for mobile robots with uncertainties and aperiodic sampling. The method combines cooperative circumnavigation guidance at the kinematic level and a robust anti-disturbance kinetic control protocol at the kinetic level. Aperiodic sampling based extended state observers are used to provide precise disturbance estimates and a nonnegative threshold-based event-triggering condition is designed for communication scheduling. The effectiveness of the algorithm is verified through simulations.

Summary: Global estimates of plastic inputs into the environment are uncertain due to limited waste management data, resulting in significant discrepancies in mismanagement rates across different studies. Some major plastic-producing countries, such as China, Russia, and Indonesia, also show large differences in mismanagement estimates. These discrepancies hinder policy design and mitigation efforts.

Summary: Contractional relay zones between normal faults can have multiple antithetic faults similar to Riedel shear zones. The antithetic faults transfer displacement between synthetic faults in the relay zones. The throw on antithetic faults is constant, while the throw profile on synthetic faults is stepped, occurring at branchpoints with abutting R' shears. Fault displacement transfer occurs through block rotation and translation within the relay zone. As fault throw increases, the relay zones are bypassed by the linkage of synthetic faults, preserving the original structure within the fault zone.

Summary: This study investigates the geometrical and dynamic properties of the turbulent/non-turbulent interface in separation and reattachment flow. The interface properties vary consistently with the vortex structure and are strongly influenced by the shear motion of the fluid and the shedding vortex. This study provides new insights into turbulent diffusion and the effects of separated flow and shedding vortices on the interface properties.

Summary: This study uses radar interferometry to analyze the deformation associated with the 2015 Dajal blind earthquake at the eastern boundary of the Sulaiman Fold Thrust (SFT) in Central Pakistan. The results show that the earthquake ruptured the Base of Boundary Thrust and caused folding, located approximately 30 km away from the nearest surface exposure.

Summary: This study reveals the contribution of frontal thrust slip to tsunami generation by modeling seafloor deformation using fault-bend folding theory. The results show that frontal thrust slip generates lower tsunami energies compared to slip on the down-dip decollement, indicating that slip on the down-dip decollement plays a dominant role in the tsunami generation process of tsunami earthquakes.

Summary: Temperature difference and its duration are important factors affecting thermoelectric performance. In this study, thermal rectifiers are used to create in-plane temperature differences. The arrangement of thermoelectric legs and the thickness of the rectifiers influence the temperature distribution. These novel thin-TEGs have potential applications in distributed sensors and wearable devices.

Summary: Articulated robots, such as manipulators, need to operate in uncertain and dynamic environments, where interaction with human coworkers is necessary. A new singularity index introduced in the paper provides an effective measure of proximity to singular configurations and avoids the failure modes and difficulties of common indices. Experimental results show that optimization based on the new index outperforms traditional manipulability maximization techniques for reaching and path following tasks.

Summary: This study describes an atypical detachment zone in Thailand occurring within a relatively strong Permian carbonate lithology, in contrast to classic detachment zones defined by weak lithologies. The key differences between stratigraphic members that led to the development of this detachment zone are bedding spacing and clay content.

Summary: The study investigates the feasibility of using basalt-enhanced weathering for carbon sequestration on agricultural land. It finds that the effectiveness of this method is dependent on using particle sizes smaller than 10 μm. If implemented on a large scale with particles of this size, it could potentially remove about 2% of Austria's annual greenhouse gas emissions, but challenges such as the energy requirements for grinding and uncertainties in field weathering rates still need to be addressed through further research.

Summary: The study found that brittle boudinage depends on the ratio of grain size and layer thickness of the amphibolite, with strain diffusing throughout thin layers and localizing once layer thickness exceeds a certain threshold. Different types of fractures develop in layers of varying thickness, with shear fractures forming in thicker layers and extensional fractures in thinner layers. Additionally, there is a trend of progressive embrittlement during cooling, leading to increasing fracture density and a switch from shear to extensional fracturing.

Summary: While both the COVID-19 crisis and the environmental crisis share similarities, they also exhibit significant differences. The linear correlation between problems and solutions in the COVID-19 crisis contrasts with the complexity and disconnected nature of challenges in the environmental crisis, making it more difficult for humans to perceive and address.

Summary: This study analyzed the microstructure of a fault gouge from a low-angle normal fault in the European Alps, revealing a multistage history of deformation from ductile to brittle. The predominant deformation mechanism in the fault gouge was viscous-frictional behavior at the brittle-ductile transition, likely facilitated by phyllosilicates and graphite lubrication.
