Are 2D semiconductors ready for next‐generation IC application? In article number 2202472, Yufeng Xie, Lifeng Bian, Wenzhong Bao, and co‐workers present a wafer‐scale demonstration by circuit‐level fabrication on a 4‐inch MoS2 wafer. While pass‐transistor configuration is more like an expedient to build logic circuits based on n‐type MoS2, future development should add complementary...
2D semiconductors, such as molybdenum disulfide (MoS2), have attracted tremendous attention in constructing advanced monolithic integrated circuits (ICs) for future flexible and energy‐efficient electronics. However, the development of large‐scale ICs based on 2D materials is still in its early stage, mainly due to the non‐uniformity of the individual devices and little investigation of device and...
We study the improved cuckoo search algorithm to promote the capability of spectrum sensing in satellite cognitive systems in this paper. We consider the application scenario of satellite network, which has relatively concise structures and flexible networking modes. The sharable frequency bands are divided into a number of subchannels, and cognitive users should discover unoccupied channels to access...
Social networks contain a tremendous amount of node and linkage data, providing unprecedented opportunities for a wide variety of fields. As the world's fourth largest disease, depression has become one of the most significant research subjects. Previously, a depression classifier has been proposed to classify the users in online social networks to be depressed or not, however, the classifier takes...
