Willis环变异与缺血性卒中相关性的研究进展 Research Progress of the Correlation between Variation in the Circle of Willis and Ischemic Stroke

Zhongguo cuzhong zazhi
通过尸体解剖和MRA等影像学技术，学者们发现Willis环存在变异，并将其分为不同类型。依托MRA技术，根据Willis环不同动脉段直径大小，可将Willis环分为4种类型。研究发现不同类型的Willis环与缺血性卒中的发病、发生部位及复发有关，然而不同类型的Willis环与缺血性卒中的严重程度及预后的相关性存在一定的争议。本文就Willis环变异与缺血性卒中的相关性进行综述。 Abstract: In the evaluation of autopsy and MRA technology ...

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

Advanced Functional Materials, EarlyView.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.
