Maternal negative expressiveness and preschool children's problem behaviors: Social information processing perspective

Yuwei Huang, Wan Ding, Siman Liu

Maternal negative expressiveness has been linked to increased internalizing and externalizing problem behaviors in preschool children, yet the underlying mechanisms remain poorly understood. This study examined the association between maternal negative expressiveness and preschool children's problem behaviors, with a particular focus on …

Three-dimensional flat bands and possible interlayer triplet pairing superconductivity in the alternating twisted NbSe 2 moiré bulk

Siman Liu, Peng Chen, Shihao Zhang

Abstract Moiré superlattices hosting flat bands and correlated states have become a central focus in condensed matter research. Using first-principles calculations, we investigate three-dimensional flat bands in alternating twisted NbSe 2 moiré bulk structures, which exhibit stronger interlayer interactions than twisted bilayer …

Enhancing Volatile Fatty Acid Accumulation in Seaweed-Arrested Anaerobic Digestion via a Two-Tier Framework of Engineering Diagnostics and Microbial Surveillance

Zhiyuan Zhao, Siman Liu, Hasan Nikkhah, Yidan Zhang et autres

Abstract This study presents a two-tier framework for brown seaweed–arrested anaerobic digestion (SW-AAD) by coupling engineering diagnostics (tier-1) with microbial surveillance (tier-2) to transform conventional digesters into volatile fatty acid (VFAs) biorefineries. In 70-day lab-scale batch tests (volume: 2 L), engineering diagnostics …

Responsive nanomedicine strategies achieve pancreatic cancer precise theranostics

Zixiang Tang, Yating Zheng, Linhong Deng, Yuxing Zhao et autres

Pancreatic ductal adenocarcinoma (PDAC), the predominant subtype of pancreatic cancer, ranks among the deadliest malignancies worldwide, with a 5-year survival rate remaining below 13 %. Its poor prognosis stems from complex anatomical barriers, a dense and heterogeneous tumor microenvironment (TME), and intricate …

Occurrence, potential sources, and ecological risk of current-use pesticides in mangrove sediments from South China

Ruotong Wu, Siman Liu, Yao-Ping Wang, Huizhen Li et autres

Mangrove forests act as sinks for contaminants carried by inland runoff, but the occurrence and potential ecological risk of current-use pesticides (CUPs) in mangrove sediments are limitedly known. In this study, 75 pesticides (including 57 insecticides, 13 herbicides, and five fungicides) were …

Hysteroscopic treatment for interstitial pregnancy: A case report

Siman Liu, Yujie Huang, Lin Xiu

Interstitial pregnancy is a rare form of ectopic pregnancy in which the gestational sac implants in a unique location within the uterus. Rupture of an interstitial pregnancy can lead to severe, potentially life-threatening uterine hemorrhage. Common treatment options include laparoscopic surgery to …

Azuperylene: The Nonalternant Isomer of Perylene

Siman Liu, Marcos Díaz‐Fernández, Menglin Zhang, Fei Huang et autres

Abstract The isoelectronic isomer of perylene, hereafter called as azuperylene, has been prepared. Electronic structure analysis reveals that the new isomer can be described as a union of two antiparallel azulenes in which the azulene‐type aromatic character of the starting azulene is …

Layer-dependent exciton dynamics in InSe/WS 2 heterostructures

Siyao Li, Yufan Wang, Zhiqiang Ming, Yong Liu et autres

Abstract Understanding interlayer charge transfer is crucial for elucidating interface interactions in heterostructures. As the layer number can significantly influence the interface coupling and band alignment, the charge transfer behaviors can be largely regulated. Here, we constructed two-dimensional (2D) heterostructures consisting of …
