Reconfigurable computing: a promising microchip architecture for artificial intelligence
Shaojun Wei
Today, integrated circuit technology is approaching the physical limit. From performance and energy consumption perspective, reconfigurable computing is regarded as the most promising technology for future computing systems with excellent feature in computing and energy efficiency. From the perspective of computing performance, compared with single thread performance stagnation of general purpose processors (GPPS), reconfigurable computing may customize hardware according to application requirements, so as to achieve higher performance and lower energy consumption. From the perspective of economics, a microchip based on reconfigurable computing technology has post-silicon reconfigurability, which can be applied in different fields, so as to better share the cost of non-recurring engineering (NRE). High computing and energy efficiency together with unique reconfigurability make reconfigurable computing one of the most important technologies of artificial intelligent microchips.

Lab-on-CMOS — an in-vitro diagnostic (IVD) tool for a healthier society
Pui-In Mak
Towards a sustainable healthcare system, the clinical-grade diagnostic platform should be decentralized into low-cost consumer-grade handheld devices, for broadly and early disease screening and diagnosis. The joint advancement of CMOS biosensors and signal-processing capability has recently transformed bulky laboratory instruments into handheld devices, leading to cost, size and weight reduction by orders of magnitude. This article gives a glimpse of the lab-on-CMOS in-vitro diagnostic (IVD) tools for point-of-care applications.

Major scientific accomplishments of Prof. Kun Huang
Jianbai Xia
The 100th anniversary of the birth of Prof. Kun Huang is in this year. Prof. Huang is a paragon of the older generation of Chinese scientists. He had made great achievements in solid state physics. After the founding of the People’s Republic of China, he returned to China immediately, and devoted himself to education. He and Prof. Xide Xie initiated the research of semiconductors in China, and established the solid state physics major at Peking University, which has trained a large number of talents for China. In 1977, he became the director of the Institute of Semiconductors of the Chinese Academy of Sciences. Led by Prof. Huang, together with Prof. Shouwu Wang, Prof. Lanying Lin and Prof. Shoujue Wang, the semiconductor institute independently overcomes many difficulties and created a group of critical devices which were on international embargo but urgently needed by China. Furthermore, he also made new contributions in the field of semiconductor superlattices. Under his leadership, the State Key Laboratory of Semiconductor Superlattices became one of the internationally leading laboratories. The following are the major scientific contributions of Prof. Kun Huang. The 100th anniversary of the birth of Prof. Kun Huang is in this year.

Families of magnetic semiconductors — an overview
Tomasz Dietl, Alberta Bonanni, and Hideo Ohno
The interplay of magnetic and semiconducting properties has been in the focus for more than a half of the century. In this introductory article we briefly review the key properties and functionalities of various magnetic semiconductor families, including europium chalcogenides, chromium spinels, dilute magnetic semiconductors, dilute ferromagnetic semiconductors and insulators, mentioning also sources of non-uniformities in the magnetization distribution, accounting for an apparent high Curie temperature ferromagnetism in many systems. Our survey is carried out from today's perspective of ferromagnetic and antiferromagnetic spintronics as well as of the emerging fields of magnetic topological materials and atomically thin 2D layers.
