Yass is an open-source, SaaS (software as a service) framework designed primarily for building applications using the Python programming language. It provides a structured way to develop web applications, particularly emphasizing rapid development and deployment. Yass typically includes features such as user authentication, database integration, and API support, making it easier for developers to create scalable and maintainable applications.

Sergey Piletsky is a prominent scientist known for his work in the field of analytical chemistry and biochemistry. He is particularly recognized for his contributions to the development of molecularly imprinted polymers (MIPs), which are synthetic materials that can selectively bind specific molecules, making them useful in various applications such as drug delivery, sensors, and environmental monitoring. Piletsky's research has focused on improving the design and functionality of MIPs, as well as exploring their applications in various disciplines.

Computational creativity is an interdisciplinary field that explores the creative capabilities of computer systems and algorithms. It involves the study and development of computer programs that can generate novel and valuable ideas, concepts, artifacts, or solutions, typically associated with human-like creativity. Key aspects of computational creativity include: 1. **Algorithmic Creativity**: Developing algorithms that can produce creative outputs, such as poetry, artwork, music, or even scientific theories.

Community informatics is a field that focuses on the use of information and communication technologies (ICT) to support and empower communities. It emphasizes the relationship between technology and community development, aiming to enhance local practices, foster social connections, and address community needs. Here are some key aspects of community informatics: 1. **Empowerment**: Community informatics seeks to empower local communities by providing access to information, resources, and technologies.

The term "artificial intelligence arms race" refers to a competitive situation among nations, corporations, or groups to develop and deploy advanced artificial intelligence technologies at the fastest pace, often with military or strategic applications in mind. This race can involve a variety of AI technologies, including machine learning, autonomous systems, natural language processing, and others that have potential applications in defense, security, and international power dynamics.

Hydroinformatics is an interdisciplinary field that combines hydrology, computer science, and information technology to enhance the understanding, management, and decision-making processes related to water resources. It utilizes computational tools, models, and data analysis techniques to study and solve various problems associated with hydrological systems, including water quality, water supply, flood forecasting, and watershed management.

The Todd–Coxeter algorithm is a method used in group theory, specifically for computing the orbit and stabilizer of elements in a permutation group, and for finding a presentation of a group given by generators and relations. It's particularly useful in the study of finite groups and is often used in computational group theory.
