Atomic structure and electronic band structure are fundamental properties for understanding the mechanism of superconductivity. Motivated by the discovery of pressure-induced high-temperature superconductivity at 80 K in the bilayer Ruddlesden-Popper nickelate La3Ni2O7, the atomic structure and electronic band structure of the trilayer nickelate La4Ni3O10under pressure up to 44.3 GPa are investigated. A structural transition from the monoclinic P21/a space group to the tetragonal I4/mmm around 12.6-13.4 GPa is identified, accompanied by a drop of resistance below 7 K. Density functional theory calculations suggest that the bonding state of Ni 3dz2orbital rises and crosses the Fermi level at high pressures, which may give rise to possible superconductivity observed in resistance under pressure in La4Ni3O10. The trilayer nickelate La4Ni3O10shows some similarities with the bilayer La3Ni2O7and has unique properties, providing a new platform to investigate the underlying mechanism of superconductivity in nickelates.

VUCA情境下供应链韧性建设是促进供应链高质量发展的关键。本文从人机交互和具象人工智能(AI)认知理论相结合的视角出发,以迈创为案例分析对象,探究了AI驱动下供应链韧性的形成与动态演进过程,以及AI对供应链韧性的作用机制。本文提出基于具象AI认知的人机交互理论,即人机交互的目标协调、行为协调和决策协调过程伴随着人对AI的认知由透明性到负责性,再到公平性的动态演化。这一过程驱动了由适应型供应链韧性塑造到持续型供应链韧性塑造,再到变革型供应链韧性塑造的三阶段跃迁。此外,揭示了AI在驱动供应链韧性塑造过程中所发挥的差别性作用及其梯次发展特征,即AI的作用不仅是算力表现的决策支持,还是一种协调和规范机制。这表现为,随着基于具象AI认知的人机交互的深化,AI的作用性质由工具性演变为战略性,作用范围由单点扩展至全链,作用角色由被动支持转化为主动参与。本文拓展了人机交互理论,阐明了AI驱动供应链韧性形成与演进的底层机理,丰富了数字经济时代供应链韧性领域的理论探索。

A highly immunosuppressive tumor microenvironment(TME)and the presence of the blood‒brain barrier are the two major obstacles to eliciting an effective immune response in patients with high-grade glioma(HGG).Here,we tried to enhance the local innate immune response in relapsed HGG by intracranially injecting poly(I:C)to establish a robust antitumor immune response in this registered clinical trial(NCT03392545).During the follow-up,12/27(44.4%)patients who achieved tumor control concomitant with survival benefit were regarded as responders in our *** found that the T-cell receptor(TCR)repertoire in the TME was reshaped after poly(I:C)*** on the RNA-seq analysis of tumor samples,the expression of annexin A1(ANXA1)was significantly upregulated in the tumor cells of nonresponders,which was further validated at the protein *** vitro and in vivo experiments showed that ANXA1 could induce the production of M2-like macrophages and microglia via its surface receptor formyl peptide receptor 1(FPR1)to establish a Treg cell-driven immunosuppressive TME and suppress the antitumor immune response facilitated by poly(I:C).The ANXA1/FPR1 signaling axis can inhibit the innate immune response of glioma patients by promoting an anti-inflammatory and Treg-driven ***,ANXA1 could serve as a reliable predictor of response to poly(I:C),with a notable predictive accuracy rate of 92.3%.In light of these notable findings,this study unveils a new perspective of immunotherapy for gliomas.
