Intraoperative tracking of laparoscopic instruments is often a prerequisite for computer and robotic-assisted interventions. While numerous methods detecting, segmenting medical based on endoscopic video images have been proposed in the literature, key limitations remain to be addressed: Firstly, robustness, that is, reliable performance state-of-the-art when run challenging (e.g. presence blood, smoke or motion artifacts). Secondly, generalization; algorithms trained specific intervention...

Alkylnitriles play important roles in many fields because of their unique electronic properties and structural characteristics. Incorporating cyanoalkyl with characteristic spectroscopy reactivity into amino acids peptides is special interest for potential imaging therapeutic purposes. Here, we report a copper-catalyzed asymmetric cyanoalkylation C(sp3)-H. In the reactions, glycine derivatives can effectively couple various cycloalkanone oxime esters high enantioselectivities, reaction be...

Topological photonics has thrived in various optical systems over the past decade for fascinating properties of eliminating backscattering losses and enhancing efficiency communication systems. The demonstration topology strong light–matter coupling regimes may prove tunable devices that are immune to disorder defects or achieve extreme light confinement. Recently, topological exciton–polaritons were experimentally studied deep cryogenic temperatures. As another elementary quasiparticle...

Amodal Instance Segmentation (AIS) endeavors to accurately deduce complete object shapes that are partially or fully occluded. However, the inherent ill-posed nature of single-view datasets poses challenges in determining occluded shapes. A multi-view framework may help alleviate this problem, as humans often adjust their perspective when encountering objects. At present, approach has not yet been explored by existing methods and datasets. To bridge gap, we propose a new task called...

The Amodal Instance Segmentation (AIS) task aims to infer the complete mask of occluded instance. Under many circumstances, existing methods treat objects as unoccluded ones, and vice versa, leading inaccurate predictions. This is because AIS do not explicitly utilize occlusion rates each object supervision. However, information critical for recognize whether target are occluded. Hence we believe it vital method be distinguishable about degree In this paper, a simple yet effective...

Capillary folding is the process of planar objects into three-dimensional (3-D) structures using capillary force. It has many important industrial applications, e.g. fabrication microelectromechanical systems. In this work, we propose a 3-D model for thin elastic sheets with pinned contact lines. The energy system consists interfacial energies between different phases and sheet. latter described by nonlinear Koiter's model, which can accommodate large deformations From energy, derive...

Perceiving the complete shape of occluded objects is essential for human and machine intelligence. While amodal segmentation task to predict mask partially objects, it time-consuming labor-intensive annotate pixel-level ground truth masks. Box-level supervised addresses this challenge by relying solely on bounding boxes instance classes as supervision, thereby alleviating need exhaustive annotations. Nevertheless, current box-level methodologies encounter limitations in generating...
