We propose a simple pairwise sigmoid loss for imagetext pre-training. Unlike standard contrastive learning with softmax normalization, the sigmoid loss operates solely on image-text pairs and does not ...

In this study, an obstacle avoidance maneuver with sigmoid function optimization is applied on the path following control of the Autonomous truck-trailer. The accumulation of trailers and traffic ...

The prevalence of intraperitoneal anastomotic leak has been reported between 0.5% to 30%, but is generally between 2% and 5% in the modern literature. [1] ...

Introduction Previous studies have demonstrated that one anastomosis gastric bypass (OAGB) is not inferior to Roux-en-Y gastric bypass (RYGB) in treating obesity. However, high level evidence ...

The inclusion criteria were as follows: (1) Upper gastrointestinal contrast imaging revealed dilated fluid-filled bowel loops proximal to the anastomosis, approximate anastomotic occlusion, and ...

Objective To examine whether preadmission glucocorticoid use increases the risk of anastomotic leakage after colon and rectal cancer resections. Design A population-based cohort study. Setting Denmark ...

Case presentation We present the case of a 61-year-old man, BMI 23, with an endoscopic diagnosis of adenocarcinoma of the sigmoid colon, which was incidentally discovered during diagnostic ...
