At present, the interaction mechanism between complex indoor environment and pseudolite signals has not been fundamentally resolved, stability, continuity, accuracy of positioning are still technical bottlenecks. In view shortcomings existing fingerprint methods, this paper proposes a hybrid CSI method for based on Ray Tracing artificial neural network (RT-ANN), which combines advantages actual...

PURPOSE Multimodality imaging has become an important adjunct of state-of-the-art radiation therapy (RT) treatment planning. Recently, simultaneous PET/MR hybrid imaging has become clinically available and may also contribute to target volume delineation and biological individualization in RT planning. For integration of PET/MR hybrid imaging into RT treatment planning, compatible dedicated RT ...

High-level resistance to multiple drugs is often detected by directly sequencing uncloned polymerase chain reaction products (population-based sequencing). It is not known, however, if this method of identifying mutations gives an accurate picture of individual viral genomes. To determine how often multidrug-resistant isolates consist of clones containing every mutation present in the populatio...

Abstract Background The outcomes of immediate autologous breast reconstruction (IABR) after partial mastectomy followed by postoperative radiotherapy (RT) in terms aesthetics, treatment-related complications, and local control are unclear. In this study, we evaluated the efficacy IABR with or without RT, thus impact radiation on flap transfer. Method A retrospective cohort study involving conse...
