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. To successfully pass the computer science exam for higher education transition, the key is to “memorize”. Today, Xuexin has … Read more
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

Introduction In modern game development, the performance of the game physics engine is crucial for creating a realistic gaming experience. From collision detection to complex rigid body motion simulation, the physics engine needs to handle a large number of mathematical calculations. The traditional Single Instruction Single Data (SISD) processing method gradually reveals performance bottlenecks when … Read more
Tumor stemness refers to a subpopulation of tumor cells that possess stem cell-like characteristics, including self-renewal, differentiation into various cell types, and the ability to survive in harsh environments. This characteristic makes tumor cells more prone to recurrence and metastasis after treatment and leads to resistance to conventional therapeutic methods. Therefore, identifying and targeting stemness-related … Read more
