Coexistence of non-trivial band topology and intrinsic magnetic order not only leads to emergent phenomena but also allows for the tunability of the exotic properties from different degrees of freedom. By performing transport measurements at synergetic extreme conditions, here we report on pressure engineering of intertwined structural, magnetic, and topological phase transitions in an antiferromagnetic Dirac semimetal NdSb. We show that the original antiferromagnetic state is strengthened in the lowpressure region while destabilized upon further compression close to the critical pressure where a structural transition from Fm-3m phase to P4/mmm phase takes place at P~18 GPa, forming a yurt-shaped evolution in response to magnetic field,pressure and temperature. Concomitant with the structural transition, NdSb simultaneously carries on a magnetic transition to the ferromagnetic state. Moreover, theoretical calculations unravel that the ferromagnetic tetragonal phase presents nontrivial features of Weyl fermions. These findings offer new important insight into the microscopic interplay among lattice, spin, and relativistic fermions in lanthanide monopnictides.

以北京、河北、宁夏、广东等地24所中小学923名中小学教师为被试,采取教学自主权量表、教学自主性量表、教师工作满意度量表,探讨了教师的教学自主权、教学自主性与工作满意度之间的关系。研究结果发现:(1)教学自主权与教学自主性均可显著预测教师工作满意度;(2)教学自主性在教学自主权与教师工作满意度之间起着完全中介作用,即教学自主权通过教师的教学自主性,对教师工作满意度有正向预测作用。

采用独立分量分析(ICA)去除脑电伪迹,AR模型提取信号特征、BP神经网络用于模式识别,对2～5种思维作业脑电信号进行了分类研究.研究结果的重要发现是:对于经过ICA去伪迹后的EEG信号,当分类特征取自20～100 Hz的高频范围时,分类准确率很高,与特征取自整个信号频段的分类结果大致相等,且大大超过利用2～35 Hz的低频EEG节律进行的分类.对于这一现象的解释是,不同思维作业过程中,大脑在工频电场作用下产生了不同的节律同化反应,致使EEG信号的高频部分带有更显著的思维调制信息,从而有利于提高分类准确率.这一现象的发现,为脑电节律同化反应提供了新的证据,也为思维脑电的高准确率分类和高精度脑-机接口的实现提供了新的方法.
