Atypical hemolytic uremic syndrome (aHUS) is a type of complement-mediated thrombotic microangiopathy (TMA), characterized by microangiopathic hemolytic anemia (MAHA), thrombocytopenia, and multi-organ damage as typical manifestations, with infection and pregnancy being the main triggers.[1] The condition of aHUS is usually quite critical. In the pre-complement treatment era, the mortality rate during the acute phase was … Read more
In C++ within Unreal Engine, TMap is an associative container used for storing key-value pairs, similar to the standard library’s std::map, but optimized for UE’s memory management and performance. Below are the basic usage and common operation examples of TMap: 1. Include Header File To use TMap, you need to include its header file: #include … Read more

【Problem】Given 4 billion unique unsigned int integers that are not sorted. Given a number, how can we quickly determine if this number exists among those 4 billion numbers? 1 billion is 9 zeros, so 4 billion is 4000000000. Our instinctive thought for a solution is to use a for loop to find the equal number, … Read more

The printf function is indispensable during microcontroller debugging, allowing developers to intuitively and conveniently obtain the current running status of the program. However, in chips like STM32, to achieve printf functionality, UART must be utilized. Is there a way to implement printing functionality solely with JLink? The answer is yes. ARM has adopted a new … Read more
STM32 has a code tracing feature, known as ITM, which is a very powerful debugging function that can replace serial input/output functionality, requiring only one I/O line to implement. Of course, its benefits are not limited to this; when debugging embedded operating system code, you will find it quite convenient. However, the focus of this … Read more
