Materials and methods: A retrospective analysis was conducted on diagnosed locally advanced who underwent MVR three medical...

Abstract Background In this study, we aimed to identify the risk factors in patients with rectal anastomotic re-leakage and develop a prediction model predict probability of after stoma closure. Methods This study was single-center retrospective analysis cancer who underwent surgery between January 2010 December 2020. Among 3225 Total or Partial Mesorectal Excision (TME/PME) for cancer, 129 experienced leakage following closure were enrolled. Risk analyzed, established re-leakage. Results...

Facing the complex marine environment, it is extremely challenging to conduct underwater acoustic target recognition (UATR) using ship-radiated noise. Inspired by neural mechanism of auditory perception, this paper provides a new deep network trained original signals with depthwise separable convolution (DWS) and time-dilated network, named perception inspired (ATCNN), then implements detection classification for signals.

Summary This paper explores a fast ray-based VSP imaging method and presents its application in the Distributed Acoustic Sensing (DAS-VSP) P-wave converted wave imaging. We use multi-template fast-advancement algorithm (MSFM) to obtain travel timetable for each shot-receiver pair, which is then summed pair before sorted at depth. Given number of common depth points (CDPs), by time. The field records are projected image domain via timetable. data stacked while folds projections position...

Background Dengue has become an increasing public health threat around the world, and climate conditions have been identified as important factors affecting transmission of dengue, so this study was aimed to establish a prediction model dengue epidemic by meteorological methods. Methods The case information data were collected from Guangdong Provincial Center for Disease Prevention Control Meteorological Bureau, respectively. We used spatio-temporal analysis characterize epidemics. Spearman...

Abstract With the development of artificial intelligence, technique improvement classification skin disease is addressed. However, few study concerned on current system International Classification Diseases, Tenth Revision (ICD)-10 Diseases and subcutaneous tissue, which now globally used for disease. This was aimed to develop a new taxonomy based cytology pathology, test its predictive effect compared ICD-10. A (Taxonomy 2) containing 6 levels (Project 2–4) developed represents individual...

<title>Abstract</title> Background Radical surgery remains the primary option for locally recurrent rectal cancer (LRRC) as it has potential to considerably extend patient's lifespan. At present, effectiveness of laparoscopic LRRC unclear.
