Practice of Micro Hydromechanical Deep Drawing
Journal of Materials Processing Technology, 2017 Abstract A micro-hydromechanical deep-drawing (MHDD) apparatus for manufacturing a micro-complex-shape components and increasing of drawn cup accuracy has been developed in this study. This apparatus with simple tooling structure and forming process can achieve high dimensional accuracy using servo press mechanics with a double-action type, one ...

Climatic, lithologic and topographic control on alpine rock fracturing and talus evolution
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.Investigating Holocene rockwall–talus systems in an Alpine valley revealed that lithologic and topographic conditions in concert with climatic‐driven stresses and time since deglaciation result in rockwall fracture patterns that control rockfall size, erosion rates and the characteristics and evolution of talus.

Design of a Hydroelectronic Solar‐Tracking System for Solar Panels
Energy Science &Engineering, Volume 14, Issue 5, Page 2600-2625, May 2026.A prototype of a passive solar‐tracking system utilizing buoyant force based on water level was developed, and its MATLAB/Simulink model was implemented. This study is expected to encourage researchers to design solar‐tracking mechanisms using metals with different thermal expansion coefficients, air, oil, and other fluids. ABSTRACT This study presents

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Melt migration in partially molten rocks is commonly described by porous flow models controlled by the hydro‐mechanical compaction length, which effectively explains melt extraction at mid‐ocean ridges. However, this framework cannot account for the paradoxical accumulation of small melt fractions into rhythmic leucosome–melanosome bands in ...

Flow Processes in a Diffluence‐Confluence Unit on a Large‐Shallow River Under Different Discharges
Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Understanding the hydrodynamics of bifurcation and confluence zones is essential for effective river management. This study investigated the complex flow structure in a large diffluence‐confluence unit (width‐depth ratio >100) of the Middle Yangtze River, utilizing systematic field observations of three‐dimensional velocities under low to high

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.Abstract Coastal zones need further investigations of beach dune erosion to improve storm‐surge protection measures in light of climate change. This study presents a hybrid approach investigating the influence of coastal foredunes on storm‐induced secondary dune erosion.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.Abstract Rock glacier kinematics are indicators of alpine climate change, yet the relative influence of thermal and hydrological processes on their motion remains poorly constrained. This uncertainty limits our ability to predict how these permafrost landforms will respond to ongoing climate change.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract Volcanic debris avalanches can transform into highly mobile debris flows, reaching long runout distances and posing significant hazards to downstream populations. This high mobility arises from complex, evolving rheological behavior driven by dynamic changes in pore pressure, internal resistance, and material properties during the flow.

Physical Modeling of Subaerial Granular Landslide‐Induced Tsunami Waves
Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.Abstract Investigating tsunamigenic landslides via physical experiments is important to increase the understanding of these often devastating events for improving disaster prevention. Landslide masses often consist of granular material, which usually is characterized by non‐uniform grain size distributions, irregular shape and pronounced surface ...

Acta Physiologica, Volume 242, Issue 3, March 2026.ABSTRACT Aim The glomerulus is a specialized microvascular unit that filters plasma through the coordinated function of podocytes and parietal epithelial cells (PECs). From this perspective, the glomerulus functions like a living hydrogeological filtration system.
