AI Article Synopsis
- Colon capsule endoscopy (CCE) is a noninvasive method used to find colorectal issues, and it needs to automatically notify patients when to take a booster laxative for effective use.
- A study analyzed data from 120 CCE-2 cases to evaluate how well the Data Recorder 3 (DR3) could detect when the capsule entered the small intestine (SB) to prompt laxative ingestion.
- The DR3 achieved a 98.3% accuracy rate in detecting the SB and alerted patients in a timely manner, indicating that CCE-2 can potentially be used outside of clinical settings.
Article Abstract
Background: Colon capsule endoscopy (CCE) is a noninvasive technique for the detection of colorectal lesions. However, for CCE to be offered as an out-of-clinic procedure, the system needs to automatically alert the patient when to ingest the laxative (booster).
Objective: We tested the reliability of the automatic detection of the small-bowel (SB) mucosa and the subsequent alert for booster ingestion by the Data Recorder 3 (DR3) of the second-generation CCE (CCE-2).
Design And Setting: Retrospective analysis.
Patients And Intervention: Data from 120 consecutive cases of CCE-2 were analyzed for proper DR3 automatic detection of the capsule entering the SB to prompt the patient to ingest the laxative booster.
Main Outcome Measurements: Accuracy of the DR3 for detecting the SB mucosa.
Results: The DR3 correctly identified the proper time for ingestion of the laxative (booster) in 118 of 120 cases, corresponding to a sensitivity of 98.3% (95% CI, 97%-100%). The median time difference between DR3 automatic SB detection to the observed entrance of the capsule into the SB was 3 minutes 30 seconds (interquartile range 2 minutes 35 seconds to 5 minutes 57 seconds).
Limitation: Retrospective analysis.
Conclusions: The 98.3% sensitivity of the DR3 for automatic identification of the SB mucosa and subsequent alert for the first laxative (booster) ingestion paves the way for CCE-2 to be offered as an out-of-clinic procedure.

Accurate building segmentation has become critical in various fields such as urban management, urban planning, mapping, and navigation. With the increasing diversity in the number, size, and shape of buildings, convolutional neural networks have been used to segment and extract buildings from such images, resulting in increased efficiency and utilization of image features. We propose a building semantic segmentation method to improve the traditional Unet convolutional neural network by integrating attention mechanism and boundary detection.

Integrated Circuits are made of various transistors that are embedded on a silicon wafer, these wafers are difficult to process and hence are prone to defects. Defecting these defects manually is a time consuming and labour-intensive task and hence automation is necessary. Deep Learning approach is better suited in this case as it is able to generalize defects if trained properly and can be a solution to segmentation and classification of defects automatically.

Background: The present study aims to (1) evaluate the autoanalyser quality control (QC) module of the Kehua Polaris c2000 automatic modularised biochemical analyser and (2) verify the impact of the analyser's automatic implementation of internal QC (IQC) testing at a set time point on the results of IQC and turnaround time (TAT).
Methods: For 5 consecutive days, three different methods were used to conduct IQC. Method 1: Internal QC was carried out at 8:00 every day.

Internal solitary waves (ISWs) propagate in stratified waters, enhancing diapycnal mixing, sediment and mass transport on shelves. They have typical wavelengths of hundreds of meters and tens of minutes periods, requiring high resolution and high frequency measurements for their sampling. But such in-situ measurements are scarce and ISWs remain largely unpredictable.

Travelable area boundaries not only constrain the movement of field robots but also indicate alternative guiding routes for dynamic objects. Publicly available road boundary datasets have outlined boundaries by binary segmentation labels. However, hard post-processes have to be done to extract from detected boundaries further semantics including the shapes of the boundaries and guiding routes, which poses challenges to a real-time visual navigation system without detailed prior maps.
