Article Synopsis
  • A study was conducted to explore how user experience and characteristics of polyps affect interactions with computer-aided detection (CADe) systems during colonoscopy.
  • The CADe system, built using YOLOv4 and trained on nearly 18,000 images, showed an improvement in polyp detection accuracy from 69.7% to 77.7% when assisted by CADe, although misdetections could decrease accuracy.
  • The results indicated that less experienced users (like nurses) benefited more from CADe assistance compared to experts, and while overall sensitivity improved for easier polyp detection, it was lower for more challenging lesions like sessile serrated lesions (SSLs).

Background: Determination of genetic relatedness between individuals plays a crucial role in resolving numerous civil cases involving familial relationships and in forensic investigation concerning missing persons. Short tandem repeats (STRs), known for their high degree of DNA polymorphism, have traditionally been the primary choice of DNA markers in genetic testing, but their application for kinships testing is limited to cases involving close kinship. SNPs have emerged as promising supplementary markers for kinship determination.

In this study, a temperature-insensitive strain sensor that detects only the strain without responding to the temperature was designed. The transport mechanism and associated temperature coefficient of resistance (TCR) of a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) thin film were modified through secondary doping with dimethyl sulfoxide (DMSO). Upon DMSO-doping, the carrier transport mechanism of the PEDOT:PSS thin film transitioned from hopping to band-like transport, with a morphological change.

The integration of quantum dots (QDs) into device arrays for high-resolution display and imaging sensor systems remains a significant challenge in research and industry because of issues associated with the QD patterning process. It is difficult for conventional patterning processes such as stamping, inkjet printing, and photolithography to employ QDs and fabricate high-resolution patterns without degrading the properties of QDs. Here, we introduce a novel strategy for the QD patterning process by treating QDs with a bifunctional ligand for acid-base reaction-assisted photolithography.
