  摘要：Dystroglycan (DG) is an extracellular matrix receptor crucial for tissue development and pathogen entry. DG harbors a long, complex glycan called matriglycan. Loss of matriglycan or reduction in its length disrupts DG function, causing dystroglycanopathies. However, the mechanism regulating matriglycan length is unknown. In this study, we found that a xylose kinase facilitated the initiation of matriglycan synthesis by adding a phosphate to the xylose of the matriglycan primer. Matriglycan elo...

  摘要：Multiferroics host simultaneous and coupled ferroic orders, allowing disparate external stimuli to induce abrupt transformations in their structures and properties. Creating multiferroicity in two-dimensional (2D) van der Waals (vdW) platforms would add the elements of strong quantum confinement, enhanced quasiparticle excitations, and wide tunability to the capabilities of these systems. In this work, we constructed vdW heterostructures of ferromagnetic triiron gallium ditelluride (Fe3GaTe2) ...

  摘要：Geochemical signatures of hotspot lavas suggest that their mantle sources are compositionally distinct, but their source locations remain elusive. Mapping hotspots to their deep origins is complicated by the presence of interconnected, low-seismic velocity networks in the mantle, where plumelike anomalies often deviate from vertical conduits. We propose a graph theory-based framework to systematically trace ensembles of plume paths using a high-resolution regional tomographic model. Applied to...
