Zeng Linghui’s Research Group at the Medical School Reveals the Mechanism by which Somatostatin Interneurons (SOM-INs) Regulate Excitatory Synapses through Astrocytic Purinergic Signaling

01 Introduction Research has confirmed that GABAergic neurons regulate synaptic excitability by activating presynaptic GABAB receptors (GABABRs). However, recent studies have shown that astrocytes also express GABABRs and can respond to the activity of GABAergic neurons. Nevertheless, it has been challenging for researchers to distinguish or overlook whether astrocytic GABABRs are involved in the mechanisms … Read more

A Brief History of Robot Development: Witnessing the Rise of an Era!

The history of robots is not very long. In 1959, American engineers George Devol and Joe Engelberger created the world’s first industrial robot, marking the true beginning of robotics. Engelberger studied servo theory in college, which is a theory that explores how motion mechanisms can better track control signals. Devol invented a system in 1946 … Read more

Summary of Commonly Tested Basic Knowledge Points for Computer Science in Higher Education Transition

In some provinces, the computer science exam is a mandatory subject for higher education transition.Computer science is considered relatively simple and can quickly boost scores; its review method is similar to that of liberal arts subjects.

Development and Challenges of Industrial Phased Array Ultrasonic Testing and Monitoring Systems

In the early 21st century, phased array ultrasonic technology expanded from the field of medical imaging to industrial non-destructive testing (NDT), establishing its significant position. The industrial phased array ultrasonic testing (PAUT) system utilizes multiple independently controlled elements or channels to emit and receive ultrasonic signals. Compared to traditional single-channel systems, PAUT can more accurately … Read more
