Detection of the Extended Gamma-Ray Emission around PSR J1627-4706 with Fermi-LAT Open
Based on nearly 16 yr of Fermi Large Area Telescope observations we have detected an extended GeV gamma-ray source with a significance of ∼7.6 σ , spatially coincident with the old pulsar PSR J1627-4706. The gamma-ray morphology is well ch…

Investigating the Double-Fissure Interactions of Hydraulic Concrete Under Three-Point Bending: A Simulation Study Using an Improved Meshless Method Open
Hydraulic concrete is prone to cracking and interactive propagation under complex stress, threatening its structural integrity and service life. To address limitations of traditional numerical methods (e.g., mesh dependency in FEM) and imp…
