In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

open access: yesAdvanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Evaluating the changes in soil erodibility factor (K) induced by exclosures of different ages, Kola Tembien, Tigray, Ethiopia

open access: yesDiscover Environment
Although exclosures were widely implemented to reverse land degradation processes in Tigray region, North Ethiopia, there is a lack of scientific studies on how these exclosures impact the soil erodibility factor. Therefore, this research was carried out

m6A‐Mediated Glycolysis by IL‐37 Drives T Cell Metabolic Reprogramming to Regulate Colitis

open access: yesAdvanced Science, EarlyView.
This study identifies an IL‐37/SIGIRR‐METTL14 regulatory axis that suppresses global m6A modification in CD4+ T cells. IL‐37 signaling, mediated through SIGIRR, inhibits IRAK4 and JNK phosphorylation, leading to downregulation of the methyltransferase METTL14.

A Laboratory Study of the Effects of Wildfire Severity on Grain Size Distribution and Erosion in Burned Soils

open access: yesFire
Wildfires pose a significant threat to the entire ecosystem. The impacts of these wildfires can potentially disrupt biodiversity and ecological stability on a large scale.

Erodibility of agricultural soils on the Loess Plateau of China

open access: yes, 2004
Soil erodibility is thought of as the ease with which soil is detached by splash during rainfall or by surface flow. Soil erodibility is an important factor in determining the rate of soil loss.

Disruption of Treg Homeostasis in Rheumatoid Arthritis via Ferroptosis‐Mediated ETC Collapse and TXK‐STAT3/PLCγ1 Activation

open access: yesAdvanced Science, EarlyView.
In rheumatoid arthritis, synovial Tregs accumulate but are functionally impaired due to iron overload‐induced ferroptosis. This triggers mitochondrial dysfunction and TXK tyrosine kinase‐mediated signaling, leading to Treg destabilization and inflammation.

Comparison of potential and real erodibility of soil by wind

open access: yes, 2007
Areas the most susceptible to wind erosion were chosen for the comparison of potential and real erodibility of soil by wind. All the areas are located in the Southern Moravia, the south-east of the Czech Republic.

3D Large‐Scale Subwavelength‐Resolution Sound Sheet Tomography Based on an Active and Programmable Circular Meta‐Array

open access: yesAdvanced Science, EarlyView.
A programmable 2048‐element circular ultrasound array combined with a compact acoustic lens produces a thin “sound sheet” over a large field of view, and records echoes with wide angular diversity across the ring aperture. Coherence‐enhanced beamforming converts full‐matrix data into high‐contrast tomographic slices, delivering near‐diffraction‐limited

Corals and Reef‐Dwelling Fish Regulate Carbon Storage and Cycling Processes in Coral Reef Ecosystems

open access: yesAdvanced Science, EarlyView.
Coral reefs are biodiversity hotspots, yet their role in carbon storage and cycling remains poorly understood. Using field surveys and modeling in the South China Sea, we reveal the overlooked potential of carbon storage in reef ecosystems and how reef fish, corals, and surface sediment jointly shape reef carbon reservoirs.

Wildfire effects on soil erodibility of woodlands in NW Spain

open access: yes, 2010
Knowledge of soil erodibility following wildfire is of crucial importance for prioritisation of post‐fire restoration practices for soil erosion mitigation.
