Summary: In this work, we proposed an Occlusion-Aware Spatial Propagation model to address the challenge of pose estimation of suture threads in surgery. We resolved the challenging cases caused by self-intersection of threads by modeling the region connectivity, and handled the background occlusion with the guided spatial propagation mechanism. Experimental results demonstrated that our proposed method achieved superior accuracy compared to baseline methods, indicating the effectiveness of considering occlusion and employing spatial propagation in pose estimation. Our fully automated algorithm provides a general framework for pose estimation of suturing thread without the need for external simulation, and addresses the common occlusion problem in surgery, showing promise for future autonomy of robotic surgery.

Summary: A graph-neural-network-based method is proposed to annotate bronchial trees extracted from CT images, providing fine-grained maps for intra-operative navigation. The proposed method tackles the challenge of sparse distribution and class imbalance in 3D image space by mapping branches to nodes in a graph space and assigning anatomical labels down to subsegmental level. It addresses the overlapping distribution problem of positional and morphological features by focusing on the relative position between sibling subsegments. The method achieves high accuracies for segmental and subsegmental node classification.

Summary: The sluggish kinetics of sulfur reactions on the cathode and the inadequate lithium deposition/stripping reversibility on the anode are successfully mitigated by using a single cathode modifier, In2Se3, which catalyses the polysulfide reactions on the cathode and improves lithium deposition/removal reversibility on the anode through the formation of a LiInS2/LiInSe2 containing solid electrolyte interface. This single modification approach shows excellent performance in Li-metal anode-free Li-S batteries, achieving 60% capacity retention and an average Coulombic efficiency of 98.27% after 160 cycles.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.
