In this paper, we study the performance of mixed free space optical (FSO)-radio frequency (RF) multi-user relay network with aperture selection and opportunistic user scheduling in the presence of Poisson field interference.The considered system includes multiple optical sources (apertures), one amplify-andforward (AF) relay, and multiple users.The
Lumbar spinal drain use during thoracic and thoracoabdominal aortic aneurysm repair has reduced the incidence of ischemic spinal cord injury with relatively low risk.We report a case of pneumocephalus in a 55-year-old woman who had undergone open repair of a 6.7-cm type IV Ornament thoracoabdominal aortic aneurysm.After lumbar spinal drain removal,
When heavy equipment are airdropped, the cabin cross-section is largely blocked, and rapid moving of heavy equipment will cause drastic changes in cabin pressure Boys Pants and even damage the health of cabin crew.Therefore, it is necessary to carry out numerical simulation of the pressure change in the airdrop cabin of the transport aircraft, and
