The detection and localization of bone joint regions in medical X-ray images are essential for contemporary medical diagnostics. Traditional methods rely on subjective interpretation by physicians, leading to variability and potential errors. Automated bone joint detection techniques have become feasible with advancements in general-purpose object detection. However, applying these algorithms to X-ray images faces challenges due to the domain gap. To overcome these challenges, a novel framework called effective and efficient network(EAE-Net) is proposed. It incorporates a context augment module(CAM) to leverage global structural information and a ghost bottleneck module(GBM) to reduce redundant features. The EAE-Net model achieves exceptional detection performance, striking a balance between accuracy and speed. This advancement improves efficiency, enabling clinicians to focus on critical aspects of diagnosis and treatment.

Cotton breeding for the development of early-maturing varieties is an effective way to improve multiple cropping indexes and.a.l.viate the conflict between grains and cotton in the cultivated fields in *** the present study,we aimed to identify upland cotton quantitative trait loci(QTls)and candidate genes related to early-maturity traits,including whole growth period(WGP),flowering timing(FT),node of the first fruiting branch(NFFB),height of the node of the first fruiting branch(HNFFB),and plant height(PH).An early-maturing variety,CCRI50,and.a.l.tematuring variety,Guoxinmian 11,were crossed to obtain biparental *** populations were used to map QTls for the early-maturity traits for two years(2020 and 2021).With BSA-seq analysis based on the data of population 2020,the candidate regions related to early maturity were found to be located on chromosome *** then developed 22 polymorphic insertions or deletions(Indel)markers to further narrow down the candidate regions,resulting in the detection of five and four QTls in the 2020 and 2021 populations,*** to the results of QTl mapping,two candidate regions(Indel_G286-Indel_G144 and Indel_G24-Indel_G43)were *** these regions,three genes(GH_d03G0451,GH_d03G0649,and GH_d03G1180)have nonsynonymous mutations in their exons and one gene(GH_d03G0450)has SNP variations in the upstream sequence between CCRI50 and Guoxinmian *** four genes also showed dominant expression in the floral *** expression levels of GH_d03G0451,GH_d03G0649 and GH_d03G1180 were significantly higher in CCRI50 than in Guoxinmian 11 during the bud differentiation stages,while GH_d03G0450 showed the opposite *** functional verification of GH_d03G0451 indicated that the GH_d03G0451-silenced plants showed a delay in the flowering *** results suggest that these are the candidate genes for cotton early maturity,and they may be used for breeding early-maturity cotton varieties.
