The introduction of metasurfaces has renewed Snell's law, and the can manipulate sound waves flexibly. In this paper, a coding metasurface with simple adjustable unit for wave transmission is proposed. By changing orientation movable part in fixed structure, conversion achieved between two types units phase difference 180° high transmittance (>75%). combining units, phases be regulated dynamically. Structural simulations are performed using finite-element software, beam splitting...
Objective To analyze the risk factors of liver metastasis from gastric cancer. Methods The clinical data 225 patients with cancer who had been admitted to our hospital January 1996 December 2001 were retrospectively analyzed. Synchronous was observed in 123 and metachronous 102 patients. evaluated. Results gender patients, location size foci, differentiation invasion depth cancer, Lanren classification, lymph node region Ⅷ, vascular invasion, extrahepatic metastasis, ascites peritoneal...
