Abstract Glioma remains a highly aggressive malignancy with frequent recurrence and resistance to radiotherapy and chemotherapy. BTN3A2 is a multifunctional regulatory protein originally implicated in γδ T-cell–mediated immune responses, yet its tumor-intrinsic role and mechanistic relevance in glioma are poorly defined. Here, BTN3A2 expression and prognostic associations were assessed in TCGA and CGGA cohorts and further validated by immunohistochemistry on tissue microarrays.

1. Introduction Sic materials find wide-ranging applications in advanced optical systems within the aerospace, space exploration, astronomical observation, and high-intensity laser fields [1]. However, as a ceramic material, Sic has certain drawbacks. Firstly, its surface lacks density, leading to a post-polishing roughness that fails to meet high-precision requirements [2].

Abstract : In order to meet the manufacturing requirements of modern space remote sensors for high-precision freeform optical parts, the grinding technology and its application were studied. The objective of this paper was to improve the application effect of traditional grinding technology in the processing of hard and brittle materials, and then apply it in specific fields.
