Ellipsoids Ellipsoid is a three-dimensional shape in geometry formed by rotating an ellipse around its major or minor axis. The shape of the Earth is not a perfect sphere but is closer to a flattened sphere, hence referred to as the “Earth ellipsoid.” Specifically, the Earth is slightly bulging at the equator and slightly flattened … Read more
In the Python programming language, a list is a very basic and important data structure. It allows us to store a sequence of ordered elements, which can be of any type, including numbers, strings, other lists, etc. Python’s lists provide a flexible way to organize and manipulate data. 1. Creating Lists Lists can be created … Read more
The first time I truly experienced the power of sets was while working on a user behavior analysis project for a social networking site. As I stared at the progress bar on the screen, my heart raced—I had to deduplicate 15 million user browsing records in real-time and detect abnormal behaviors. Using a list? The … Read more
1. Introduction: The Core Power of Dynamic Sequences The list, as the most flexible mutable sequence type in Python, is a core tool for handling dynamic data collections. Unlike tuples, lists support real-time modifications, dynamic expansions, and a rich set of built-in methods, making them the preferred structure for scenarios such as data collection, algorithm … Read more
Performance Revolution! Enhancing Python Key Algorithm Efficiency with C Extensions At three o’clock that morning, the CPU usage of the online server suddenly soared to 95%, and the alarm message woke me from my sleep. When I opened my laptop, I found that the data processing module I had restructured a few days ago was … Read more

Click the blue text Follow us Introduction /Introduction Fat mass and obesity-associated protein (FTO) is the first identified m6A demethylase, and its abnormal expression is associated with various cancers such as acute myeloid leukemia, melanoma, cervical cancer, and breast cancer. Developing highly sensitive and selective methods for FTO detection is crucial for early cancer diagnosis … Read more
In the field of programming, exploring solutions to mathematical problems is both an interesting and challenging task. Today, we will implement a specific mathematical problem using C language: determining whether a given positive integer can be expressed as the sum of two prime numbers. This problem is known in mathematics as “Goldbach’s conjecture”. Although this … Read more
