A Pickering emulsion is a type of emulsion that is stabilized by solid particles rather than traditional surfactants. In a typical emulsion, like oil and water, surfactants are used to reduce the surface tension between the two immiscible liquids, helping them to mix and stabilize the dispersion.

Description Logic (DL) is a family of formal knowledge representation languages that are primarily used to represent structured knowledge about the world. It is a subset of first-order logic, designed to provide a more expressive yet computationally manageable framework for reasoning about concepts (also known as classes or types) and relationships between them. ### Key Features of Description Logic: 1. **Concepts**: Represented as unary predicates, concepts define classes of objects. For example, "Person" or "Animal".

A Differential Graded Lie Algebra (DGLA) is a mathematical structure that is a generalized form of a Lie algebra. It combines the properties of a Lie algebra with those of a graded vector space and a differential operator.

Picard–Vessiot theory is a framework in differential algebra that generalizes the concepts of Galois theory to the setting of differential equations. It deals with the study of algebraic properties of differential fields—fields equipped with a derivation—and the solutions of linear differential equations.

Dysprosium is a chemical element with the symbol Dy and atomic number 66. It is classified as a lanthanide, which is a group of elements found in the f-block of the periodic table. Dysprosium is a silvery-metallic rare earth element that is known for its relatively high thermal neutron-capture cross-section, making it valuable in various nuclear applications.

"Works about the Digital Revolution" can refer to a variety of materials, including books, articles, documentaries, and films that examine the impact of digital technology on society, culture, and the economy. The Digital Revolution generally refers to the shift from analog to digital technology that began in the late 20th century and encompasses the rise of personal computers, the internet, smartphones, social media, and other digital innovations.

"Indigo Era" might refer to different contexts depending on the subject area, such as art, culture, or a specific movement. However, it isn't a widely recognized term in mainstream discussions as of my last knowledge update in October 2023.

Beal's Conjecture is a statement in number theory proposed by Andrew Beal in 1993. It asserts that if \( A^x + B^y = C^z \) holds true for positive integers \( A, B, C, x, y, \) and \( z \) with \( x, y, z > 2 \), then \( A, B, \) and \( C \) must share a common prime factor.

An Euler brick is a special type of rectangular cuboid (or box) with integer side lengths \(a\), \(b\), and \(c\) such that the lengths of the three face diagonals are also integers. Specifically, the conditions for an Euler brick are that: 1. The dimensions are positive integers: \(a\), \(b\), and \(c\). 2. The lengths of the face diagonals are also integers.

The Fermat–Catalan conjecture is a conjecture in number theory that deals with a specific type of equation related to powers of integers.

The Jacobi–Madden equation refers to a mathematical relationship that arises in the context of dynamics, particularly in the study of second-order equations and Hamiltonian mechanics. It is associated with the properties and transformations of certain integrable systems.

The Bhagavad-gita Museum is a cultural and spiritual institution dedicated to the teachings of the Bhagavad-gita, a 700-verse Hindu scripture that is part of the Indian epic Mahabharata. The museum typically aims to provide insights into the philosophical, spiritual, and historical aspects of the Bhagavad-gita, which is considered one of the most important texts in Hindu philosophy and spirituality.

The Isaac Newton Institute for Mathematical Sciences, often referred to simply as the Isaac Newton Institute (INI), is a prominent research institute located in Cambridge, England. It focuses on the field of mathematical sciences and serves as a hub for interdisciplinary research and collaboration. Established in 1992, the institute is named after Sir Isaac Newton, who is one of the most influential mathematicians and physicists in history.

Erich Regener was a German physicist known for his contributions to the field of optics and photonics. He conducted research related to lasers and optical systems. His work contributed to advancements in various technologies requiring precise optical measurement and manipulation.

The Journal of Applied Non-Classical Logics is an academic publication that focuses on the study and application of non-classical logics. Non-classical logics include various logical systems that extend or deviate from classical logic, such as modal logic, intuitionistic logic, paraconsistent logic, and others. These logics can be employed in various fields, including computer science, artificial intelligence, philosophy, and linguistics, to address problems that classical logic may not effectively handle.

In 1985, several computer companies were disestablished or went out of business, often due to the rapidly changing technology landscape and market shifts. A notable example is **Data General**, which was a significant player in the minicomputer market. Data General struggled to compete with rising technologies and eventually faced financial difficulties that led to its acquisition by EMC Corporation in 1999, but it was significantly diminished in the years leading up to that.

A Pythagorean quadruple is a set of four positive integers \( (a, b, c, d) \) such that the sum of the squares of the first three integers equals the square of the fourth integer.

"Poppet" can refer to several things depending on the context: 1. **Doll or Figurine**: Traditionally, a "poppet" is a term used for a small doll or a puppet. This can often refer to a child's toy or a handcrafted figure.
