Cutting Test Device for PDC Bit with Mixed Cutter Arrangement
Shiyou jixie, 2019 The existing PDC bit single-cutter test device is very inconvenient to adjust the parameters such as single-cutter rake angle. It is necessary to carry out frequent replacement of multiple sets of tools, which is not suitable for the mixed cutting ...

Long-distance device-independent quantum key distribution
, 2019 Besides being a beautiful idea, device-independent quantum key distribution (DIQKD) is probably the ultimate solution to defeat quantum hacking. To guarantee security, it requires, however, that the fair-sampling loophole is closed, which results in a ...

SLA2 is Associated With Immune evasion and Exhaustion of CD8+ T Cells in Gastric Cancer
Journal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.ABSTRACT The Src‐like adaptor 2 (SLA2) functions as a negative regulator of T cell receptor signalling. However, its involvement in the tumour microenvironment (TME) of gastric cancer (GC) remains unexplored. In this study, we found that SLA2 expression was significantly elevated in GC tissues, and a high level of SLA2 was associated with poor ...

Detection of the ultranarrow temporal correlation of twin beams via sum-frequency generation
, 2012 We demonstrate the ultranarrow temporal correlation (6 fs full width half maximum) of twin beams generated by parametric down-conversion, by using the inverse process of sum-frequency generation.
