Summary: Research in southern Sweden on v-shaped subglacial landforms (murtoos) shows that they are composed of heterogeneous diamicts with strong fabrics interbedded with sorted sediments, indicating ductile deformation and liquefaction. The landforms are interpreted as being created by till deposition and sedimentation from meltwater with subsequent deformation, suggesting a stepwise formation including periodic deformation events. The model proposed is based on a dynamic subglacial meltwater system similar to processes observed on the Greenland ice sheet today.

Summary: This study investigates the subglacial deformation beneath a cold-based glacier resting on permafrost in Antarctica. The researchers used a tunnel to observe the structure of the basal zone and bed of the glacier and found that ice-rich permafrost can be readily deformed by glaciers, with no clear boundary between basal ice and deforming permafrost.

Summary: This study analyzed the microbial ecology of the Skaftarkatlar subglacial lakes in Iceland, revealing a low-diversity core microbial assemblage and the dominance of chemolithoautotrophy as the main metabolism. These findings highlight the importance of in situ investigations in understanding this unique environment, as they are not reflected in enrichment cultures.

Summary: In this study, magnetorheological (MR) porous fabric composites were prepared by pretreating non-woven fabrics with lithium stearate. The rheological properties tests showed that the composite samples containing lithium stearate had improved mechanical properties and sedimentation stability compared with the MRF sample. However, the improvement effect of material performance gradually decreased with the increase of lithium stearate content.

Summary: This study compared the performance of Kevlar neat fabric and STF/Kevlar composite fabric using the picture frame test. The results showed that the STF/Kevlar composite fabric had a higher load-carrying capacity and exhibited obvious differences under different loading rates. Additionally, the STF/Kevlar composite fabric had higher shear deformation stiffness and energy absorption level.

Summary: Deformation of subglacial sediment during basal slip impacts the beds of fast-flowing glaciers and ice streams. Experiments reveal a near-linear relationship between sediment flux and slip speed, while sediment flux shows a non-monotonic, double-valued relationship with effective stress.

Summary: Post-rifting ground deformation is driven by the relaxation of stresses generated by dike intrusions. Using GNSS and InSAR velocity fields, we analyzed the post-rifting deformation from 2015 to 2020 in the Baroarbunga eruption in Iceland. The results showed uplift on both sides of the dike and horizontal displacement away from the dike after accounting for background deformation. A two-layer viscoelastic model with a 0.4 x 10(19) Pa s viscoelastic half-space and an 18 km thick elastic layer best explained the observed displacements. The model also highlighted another regime of good fit, possibly due to deformation near the dike caused by cooling compaction.

Summary: This research incorporates a mixed lubrication model and a volume-of-fluid model to study the diffusion behavior of a small amount of lubricating oil in water-lubricated bearings. The results show the existence of a backflow effect in the bearings, and increasing the shaft speed has a positive effect on oil diffusion and fluid load capacity.

Summary: In this study, two-dimensional deformation estimates derived from Persistent Scatterer Interferometric (PSI) analysis of Synthetic Aperture Radar (SAR) data were examined for their improved characterization of spatially and temporally varying deformation processes of Earth's surface. By analyzing Sentinel-1 SAR image data from 2015 to 2018, the study obtained 2D vertical and horizontal surface deformation velocities, which showed good agreement with independent GPS measurements.

Summary: This study investigates the hydroelastic coupling during the free-surface water entry of deformable spheres of different material densities, finding that elastic wave propagation scales with sphere density and that the wetted area of the sphere is closely related to sphere deformation. Predictions about the influence of sphere deformation on cavity shape can be roughly made using the m* - eta plot developed in this work.

Summary: This study investigates the kinematics of deformation in debris bands associated with an overdeepened basin in Iceland. The research reveals the presence of multiple fabric types, suggesting a complex deformation history. Furthermore, pure shear-dominated strain was observed in an ice-free sediment ridge on the glacier surface.

Summary: In this study, composite materials using different fabrics and MXene nanosheets were prepared through room temperature impregnation. The Ti3C2Tx@NWF composite was found to be the optimal flexible pressure sensor, demonstrating high sensitivity, a wide sensing range, fast response/recovery times, and excellent durability. The findings provide a basis for the rational design of MXene/textile composites as wearable pressure sensors and demonstrate the potential of these sensors in monitoring human motion and locating pressure accurately.

Summary: In this study, a digital 3D model of irregular gangue blocks was obtained using CT scanning and 3D reconstruction technology. The research focused on the influence of block shape on the properties of crushed gangue, revealing that irregular block shapes affect the void ratio and bearing capacity of the samples.

Summary: This study focuses on the timing of glacier fluctuations in the European Alps during the Younger Dryas/Early Holocene (YD/EH) transition. The findings suggest broadly synchronous behavior of glaciers across the Alps between 12 and 10 ka, indicating that common regional climate conditions had a major impact on Alpine glacier variations during this period. Additionally, similarities in glacier behavior and temperature records between the Alpine region and northern high latitudes suggest a teleconnection, with pronounced changes in seasonality between the Younger Dryas and the Early Holocene.

Summary: Paleoglacier reconstructions in the northern and southern forelands of the European Alps indicate a synchronous Late Pleistocene glacial maximum during Marine Isotope Stage 2, but strong controversy remains for the western foreland. New luminescence dating reveals two major glacier advances in the western Alpine foreland at ca. 75-60 and ca. 40-30 ka, coinciding with MIS 4 and late MIS 3, suggesting asynchrony in glacial maxima with the rest of the Alps due to atmospheric circulation reorganization over the North Atlantic in response to Northern Hemisphere ice-sheet fluctuations.

Summary: Research in the foreland of the French Western Alps has shown multiple stages of retreat or stagnation of the Lyonnais ice lobe during marine isotopic stages 4 and 2. Glaciofluvial corridors in the western part of the Lyonnais ice lobe were active during flash floods draining glacial meltwater at the Last Glacial Maximum, but are now dead valleys with terraces. Sedimentary analysis suggests these corridors correspond to tunnel valleys built during the most extensive Riss glaciation and were infilled with glacio-fluvial sediments during the Wurm maximum glacial extension.
