Background Minimally invasive resection for upper gastrointestinal tumors has been associated with favorable results. However, the role of laparoscopic surgery (LS) in the multimodal treatment of patients with advanced adenocarcinoma of the stomach or gastroesophageal junction needs further investigation. Methods Clinicopathological data of patients who underwent gastrectomy between 2005 and 2017...
Cilia are organelles that generate microfluidic flows in the lungs, central nervous system, and Fallopian tubes. Quantitative flow diagnostic remain immature. I will present a comprehensive optical imaging-based approach for quantifying cilia flow physiology.
We demonstrate a VECSEL-based degenerate laser with tunable spatial coherence. The low spatial coherence illumination is used for traditional high-speed video-microscopy and high spatial coherence illumination to extract dynamic information of blood flow in Xenopus.
We demonstrate topological defect lasers in a GaAs membrane with embedded InAs quantum dots. By introducing a disclination to a square-lattice of elliptical air holes, we obtain spatially confined lasing modes that support powerflow vortices.
