Science China Technological Sciences 2025年第1期 325-338页

Supernumerary robotic arms(Superlimb) are a new type of wearable robot that works closely with humans as a third hand to augment human operation capability. Accurate conveyance of wearers' intentions, allocation of roles, and humancentered interaction considerations are the key points in the process of human–Superlimb collaboration. This paper proposes a human-centered intention-guided leader–follower controller that relies on the dynamic modeling of Superlimb with application to load-carrying scenarios. The proposed leader–follower controller takes the human as the leader and the Superlimb as the follower, achieving effective information communication, autonomous coordination, and good force compliance between Superlimb, humans, and the environment under human safety assurance. First, the human–Superlimb dynamic system is modeled to achieve force interaction with the environment and wearer. Second, to achieve the precise intention extraction of humans, pose data from five visual odometry sensors are fused to capture the human state, the generalized position, the velocity of hands, and the surface electromyography signals from two myoelectric bracelets sensors are processed to recognize the natural hand gestures during load-carrying scenarios by a designed Swin transformer network. Then, based on the real-time distance detection between human and mechanical limbs, the security assurance and force-compliant interaction of the human–Superlimb system are realized. Finally, the human hand muscle intention recognition, human–robot safety strategy verification,and comparative load-carrying experiments with and without the proposed method are conducted on the Superlimb *** showed that the task parameters are well estimated to produce more reasonable planning trajectories, and Superlimb could well understand the wearer's intentions to switch different Superlimb actions. The proposed sensor-based human–robot communication framework motivates future studies of o

针对传统半监督自训练分类方法易导致数据集混乱,影响后续小样本树种分类精度这一问题,基于熵权法(en-tropy weight,EW)与集成学习(ensemble learning,EL)提出EW-EL的半监督小样本树种分类方法。EW-EL在传统半监督自训练分类方法的理论上引入EL的思想,以熵权法作为基础理论设计按基分类器当前训练周期下的F1分数计算的信息熵作为计算权重因子,再依信息熵越大基分类器越不稳定思想设计权重,使集成分类器分类概率更集中,减少集成分类器偏向性。结果显示,EW-EL较传统半监督自训练方法能更有效地均衡数据分布,使新加入数据的伪标签样本类别更准确。EW-EL所得到的小样本树种分类总精度(OA)为0.97、召回率(Recall)为0.96及Kappa系数为0.97,3种指标均优于监督分类、传统半监督自训练方法及利用传统EL机制所构建的半监督自训练方法。其中,EW-EL方法较融合软投票机制的半监督自训练方法,OA与Recall均提升了1%。EW-EL联合简单线性迭代聚类所制成的树种图在所选测试区内达到了94%。此外,进一步分析证明,EW-EL能通过集成诸多分类器,来实现更佳的小样本树种分类结果,更适用于低成本下的相关部门进行林业资源统计的工作。

Bifunctional bridging capping layer enables 24.5% efficiency of perovskite solar cells with polymer-based hole transport materials

Science China Chemistry 2025年第1期 350-359页

Developing a bridge capping layer between perovskite and hole transport layer materials（HTMs） in the n-i-p perovskite solar cells（pero-SCs） is an effective approach to modify the morphology of HTMs and passivate the perovskite ***, we select the quinoxaline-based bifunctional passivation agent, quinoxalin-6-yl-methylamine hydrochloride（Qx MACl）,as the bridging layer, and a D-A copolymer PBQ12 containing the same quinoxaline unit as an HTM for the n-i-p pero-SCs. Due to the π-π stacking among the common quinoxaline units in the bridge layer and HTM, Qx MACl induces the π-π stacking of the PBQ12 film and improves the film morphology of HTMs with better conductivity. Additionally, Qx MACl can effectively passivate the perovskite surface, and PBQ12 possesses appropriate energy levels and high hole mobility. The pero-SCs based on FAPbI3with PBQ12/Qx MACl treatment showed a higher power conversion efficiency（PCE） of 24.05% and outstanding stability, maintaining 95.4% and 92.1% of its initial PCE after 750 h of storage and after over 800 h of thermal annealing at 85 °C, respectively. To further enhance the PCE of the PBQ12/Qx MACl-based devices, we developed a non-metal ion dopant for the PBQ12 HTM. Through trace doping of PBQ12 HTM by the non-metal ion dopant, the PCE of the PBQ12/Qx MACl-based devices reached 25.24%（the calibrated PCE of 24.55% by the National Institute of Metrology, China）.
