The term "Austrian relativity theorists" might be a bit ambiguous, as it doesn't refer to a widely recognized group or specific school of thought within the broader field of relativity.

Australian women mathematicians have made significant contributions to various fields of mathematics, and their work has been influential both nationally and internationally. Here are a few notable Australian women in mathematics: 1. **Mary Cartwright** - An influential figure in chaos theory, she made significant contributions to mathematical applications in various fields including engineering and meteorology. 2. **Jill K. P. G.

The term "Congius" refers to a unit of liquid capacity that was used in ancient Roman measurement systems. Specifically, it represented approximately 3.28 liters (or about 0.87 U.S. gallons). The congius was part of a larger system of measurements used for various liquids, particularly in trade and commerce. Today, the term is mostly of historical interest and is not commonly used in modern measurements.

Australian mathematics has evolved significantly over the centuries, with various contributions coming from mathematicians in different eras. Here's a brief overview of notable Australian mathematicians by century: ### 19th Century - **John Stewart** (1834–1916): He was one of the early influential figures in Australian mathematics and made contributions to mathematics education. - **George M. Allen** (1880–1942): Known for his work on mathematical analysis and differential equations.

Australian anti-nuclear weapons activists are individuals and groups in Australia that campaign against the development, proliferation, and use of nuclear weapons. This movement has been active since the mid-20th century, particularly in response to the threat posed by nuclear arms, as well as the testing of nuclear weapons in the Pacific.

A gene co-expression network is a biological network that represents the relationship between genes based on their expression levels across different conditions, time points, or samples. In such a network, nodes represent genes, and edges (connections between nodes) indicate a correlation or co-expression between those genes. ### Key Features of Gene Co-expression Networks: 1. **Nodes and Edges**: - **Nodes**: Each node in the network corresponds to a specific gene.

ADS-AC stands for "Active Directory Federation Services - Access Control." It is a component of Microsoft's Active Directory Federation Services (AD FS). AD FS is a service that provides single sign-on (SSO) capabilities, allowing users to authenticate using their organization's credentials to access external applications and services, such as cloud-based applications, without needing to create and manage separate usernames and passwords for each application.

A polarized membrane is a type of biological membrane that has a difference in electric charge across its surface, which creates an electric potential known as membrane potential. This phenomenon is particularly significant in the context of nerve and muscle cells, where the polarization of the membrane plays a critical role in the generation and propagation of electrical signals.

Advanced Armament Corporation (AAC) is a company that specializes in the design and manufacture of firearm suppressors, weapons accessories, and various firearm-related products. Founded in the 1990s, AAC gained a reputation for its innovative suppressor technology and high-quality sound suppression solutions for a range of firearms, including rifles and handguns.

The Advanced Electric Propulsion System (AEPS) refers to innovative spacecraft propulsion technologies that utilize electric power to generate thrust. These systems are designed to achieve greater efficiency, higher specific impulse, and longer mission durations compared to traditional chemical propulsion systems. AEPS includes various technologies, such as: 1. **Ion Propulsion**: This method uses electric fields to accelerate ions, creating thrust.

Advanced Engineering Materials is a field that focuses on the development, processing, and application of materials that possess superior properties and functionalities compared to conventional materials. This area encompasses a wide range of materials, including metals, polymers, ceramics, composites, and biomaterials, and it aims to innovate and enhance material performance for various engineering applications.

G-spectrum refers to a concept in the field of algebraic topology, specifically in the study of stable homotopy theory. It is the construction of a certain type of spectrum that captures the homotopical information of a given space or a kind of generalized space. A spectrum is a sequence of spaces (or more generally, objects in a stable category) along with stable homotopy equivalences that allow for a systematic study of stable phenomena in topology.

The Advanced Stirling Radioisotope Generator (ASRG) is a type of power generation technology designed to provide electricity for space missions using radioisotope materials. It is based on two main technologies: the Stirling engine and radioisotope power systems. **Key Features of the ASRG:** 1. **Stirling Engine Principle**: The ASRG utilizes Stirling engines, which are external combustion engines that convert heat energy into mechanical work.

In mathematics and physics, the terms "pole" and "polar" can refer to different concepts depending on the context. Here are a few key meanings: ### In Geometry: 1. **Pole**: - In spherical geometry, a pole usually refers to the topmost point of a sphere or a point on a sphere that is opposite to the equator.

Western Approaches refers to a significant geographical area in the North Atlantic Ocean, specifically the waters off the western coast of Europe, including parts of the British Isles, France, and beyond. It is often associated with naval and maritime operations, particularly during World War II, when the region was a critical theater of war. In a historical context, "Western Approaches" may also refer to the naval command center established in Liverpool, England, during World War II.

An aeolipile, also known as a steam engine or Hero's engine, is a device that converts thermal energy into mechanical energy through the use of steam. It consists of a simple chamber that holds water and is equipped with one or more outlet pipes at right angles. When the water inside the chamber is heated, it turns to steam, which exits through the pipes. The rapid expulsion of steam causes the aeolipile to rotate, demonstrating the principle of reaction propulsion.

The term "kisrhombille" refers to a specific geometric structure or a type of polyhedron in the family of Archimedean solids. The kisrhombille, also known as the "kisarhombille" or "kisarhombic dodecahedron," is comprised of hexagons and triangles.
