Mitigating Ion Migration with an Ultrathin Self‐Assembled Ionic Insulating Layer Affords Efficient and Stable Wide‐Bandgap Inverted Perovskite Solar Cells

Haodan Guo, Yanyan Fang, Yan Lei, Jinpeng Wu, more

Small > 19 > 38 > n/a - n/a

Wide‐bandgap perovskite solar cells (PSCs) are attracting increasing attention because they play an irreplaceable role in tandem solar cells. Nevertheless, wide‐bandgap PSCs suffer large open‐circuit voltage (V_OC) loss and instability due to photoinduced halide segregation, significantly limiting their application. Herein, a bile salt (sodium glycochenodeoxycholate, GCDC, a natural product), is used...

Coordination of intertracheid pit traits and climate effects among cycads

Yu‐Kun Pang, Lan‐Li Qin, Tian‐Hao Zhang, Jin‐Yan Lei, more

Physiologia Plantarum > 175 > 3 > n/a - n/a

Interconduit pit membranes, which are permeable regions in the primary cell wall that connect to adjacent conduits, play a crucial role in water relations and the movement of nutrients between xylem conduits. However, how pit membrane characteristics might influence water‐carbon coupling remains poorly investigated in cycads. We examined pit characteristics, the anatomical and photosynthetic traits...

Residual Quantum Effects beyond Mean‐Field Treatment in Quantum Optics Systems

Yue‐Xun Huang, Ming Li, Zi‐Jie Chen, Yan‐Lei Zhang, more

Laser & Photonics Reviews > 17 > 4 > n/a - n/a

Mean‐field treatment (MFT) is frequently applied to approximately predict the dynamics of quantum optics systems. It simplifies the system Hamiltonian by neglecting the quantum statistics of certain modes that are driven strongly by lasers or couple weakly with other modes. However, the neglected quantum correlations between different modes result in unanticipated quantum effects and might lead to...

Phylogenomic relationships and species identification of the olive genus Olea (Oleaceae)

Wen‐Pan Dong, Jia‐Hui Sun, Yan‐Lei Liu, Chao Xu, more

Journal of Systematics and Evolution > 60 > 6 > 1263 - 1280

The olive genus Olea includes c. 30–40 taxa in three subgenera (Olea, Tetrapilus, and Paniculatae) within the family Oleaceae. Historically, the Olea genus was classified into four groups that were overall well supported by reconstructed phylogenies, despite incomplete sampling of subgenus Tetrapilus and poor resolution within clades. These analyses also showed that the genus was not monophyletic...

A Polyvalent Peptide CD40 Nanoagonist for Targeted Modulation of Dendritic Cells and Amplified Cancer Immunotherapy

Muhetaerjiang Mamuti, Yi Wang, Yong‐Dan Zhao, Jia‐Qi Wang, more

Advanced Materials > 34 > 24 > n/a - n/a

Targeted immunomodulation through biomolecule‐based nanostructures, especially to dendritic cells (DCs), holds great promise for effective cancer therapy. However, construction of high‐performance agonist by mimicking natural ligand to activate immune cell signaling is a great challenge so far. Here, a peptide‐based nanoagonist toward CD40 (PVA‐CD40) with preorganized interfacial topological structure...

Robust Self‐Assembled Molecular Passivation for High‐Performance Perovskite Solar Cells

Haodan Guo, Yanyan Fang, Hong‐Bo Cheng, Jinpeng Wu, more

Angewandte Chemie International Edition > 61 > 25 > n/a - n/a

Defect passivation via post‐treatment of perovskite films is an effective method to fabricate high‐performance perovskite solar cells (PSCs). However, the passivation durability is still an issue due to the weak and vulnerable bonding between passivating functional groups and perovskite defect sites. Here we propose a cholesterol derivative self‐assembly strategy to construct crosslinked and compact...

Dynamic event‐triggered control for singularly perturbed systems

Tong Hua, Jiang‐Wen Xiao, Yan Lei, Wu Yang

International Journal of Robust and Nonlinear Control > 31 > 13 > 6410 - 6421

In this paper, we consider event‐triggered control for linear singularly perturbed systems. A composite event‐triggered controller is proposed based on the decoupled slow and fast subsystems which are triggered simultaneously. Two internal dynamic variables are introduced in the event‐triggered mechanism. The results indicate that the systems can achieve asymptotic stability with the proposed event‐triggered...

Improving deep‐learning‐based fault localization with resampling

Zhuo Zhang, Yan Lei, Xiaoguang Mao, Meng Yan, more

Journal of Software: Evolution and Process > 33 > 3 > n/a - n/a

Many fault localization approaches recently utilize deep learning to learn an effective localization model showing a fresh perspective with promising results. However, localization models are generally learned from class imbalance datasets; that is, the number of failing test cases is much fewer than passing test cases. It may be highly susceptible to affect the accuracy of learned localization models...

Yan‐Lei Zhu, Hong‐Ru Deng, Mi Zhou, Mingxuan Li, more

Journal of Cardiac Surgery > 36 > 2 > 726 - 730

Although peripheral arterial embolism is a common vascular disease, abdominal aortic saddle embolism (ASE) is rare. However, ASE is considered to be quite severe. A rapid and accurate diagnosis followed by timely and appropriate medical intervention is the key to minimize the risk of severe complications and reduce the risk of mortality. We report the case of an 84‐year‐old female patient who was...
