Longer Right Colon Withdrawal Time and Retroflexion Duration Significantly Increases Adenoma Detection Rate: A Randomized Controlled Trial at Three Endoscopy Centers
Purpose Detection of adenomas is the foundation of colorectal cancer screening utilizing screening colonoscopies. Adenoma detection rate (ADR) is an increasingly utilized core quality measure for colonoscopies. Colonoscopy is an effective tool to prevent colon cancer but missed lesions can lead to …

Real-time Intrusion Detection using Multidimensional Sequence-to-Sequence Machine Learning and Adaptive Stream Processing
… There are host-based and network-based Intrusion Detection Systems (IDS's), of which there are each signature-based and anomaly-based detection methods. An anomalous network behavior can be defined as an intentional violation of the expected sequence of packets. In a real-time network-based IDS, …
