Deep Learning–Based Detection of Sessile Serrated Lesions in Colonoscopy Images: Optimization of a YOLOv3 Framework With Mucus Cap Feature Enhancement for Sessile Serrated Lesion Detection

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Background and Aim Sessile serrated lesions (SSLs) are difficult to detect during colonoscopy via standard white‐light imaging (WLI) because they are flat, have indistinct borders, and are often hidden by mucus caps.

Comparative Genome‐Wide Association Studies of Metabolites and Grain‐Related Traits in Common Wheat

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The metabolome is highly diverse and the closest layer to phenotype; therefore, it is commonly regarded as a bridge between the genome and phenome in plants. Here, we performed large‐scale metabolome analysis using liquid chromatography–tandem mass spectrometry (LC–MS/MS) and 33 grain‐related traits in a diverse panel of natural accessions and

Trade Reform in Services: Structural Change and Production Networks

open access: yesReview of International Economics, EarlyView.
ABSTRACT We study the effects of services trade reforms in a multi‐country multi‐sector quantitative trade model with input–output linkages. Services matter both as final consumption and as production inputs: cheaper traded services lower household prices directly and reduce the costs of downstream producers also indirectly.
