Polyacrylamide gel electrophoresis (PAGE) is a laboratory technique used to separate macromolecules, primarily proteins and nucleic acids, based on their size and charge. The method involves the use of a polyacrylamide gel, which serves as a medium through which the molecules can migrate when an electric field is applied.
"Charmides" is one of Plato's dialogues, featuring a conversation between the philosopher Socrates and several Athenian youths, including Charmides, a young nobleman. The dialogue primarily explores the nature of temperance or moderation (sophrosyne in Greek) and relates to broader themes of self-knowledge, wisdom, and the ethical conduct of individuals. In the dialogue, Socrates engages Charmides in an examination of what it means to be temperate.
PuTTY is a free and open-source terminal emulator, serial console, and network file transfer application. It was originally developed for Windows, but it has since been ported to other operating systems, including Unix and Linux.

Gell-Mann matrices are a set of matrices that are used in quantum mechanics, particularly in the context of quantum chromodynamics (QCD) and the mathematical description of the behavior of particles such as quarks and gluons. They are a generalization of the Pauli matrices used for spin-1/2 particles and are essential for modeling the non-abelian gauge symmetry of the strong interaction.
The Newman–Janis algorithm is a method used in general relativity and theoretical physics for generating new solutions to the Einstein field equations. Specifically, it is often utilized to derive rotating black hole solutions from static ones. The algorithm is named after its developers, Eric Newman and Roger Penrose. The typical application of the algorithm involves starting with a known stationary solution (like the Schwarzschild solution for a non-rotating black hole) and transforming it to create a rotating solution (like the Kerr solution).
"Note G" can refer to different things depending on the context. Here are a few possibilities: 1. **Musical Notation**: In music, G is one of the notes in the musical scale. It is the fifth note of the C major scale and can be found on various instruments including piano, guitar, and others. In the context of a scale, it can be seen as a tonic in the G major scale or the dominant in the C major scale.
The "right to explanation" refers to the concept that individuals should have the ability to understand the decisions made about them by automated systems, particularly in the context of artificial intelligence (AI) and machine learning. This right is particularly associated with the General Data Protection Regulation (GDPR) in the European Union, specifically Article 22, which addresses automated individual decision-making.
Run to completion scheduling is a scheduling policy primarily used in computing and real-time systems where a task is allowed to run to its completion without being preempted by other tasks or processes. This means that once a task starts executing, it is not interrupted until it has finished running.
The term "unrestricted algorithm" does not refer to a specific, well-defined concept in computer science or mathematics, but it can be interpreted in a few different ways depending on the context. Here are a couple of interpretations: 1. **General Definition**: An "unrestricted algorithm" could refer to an algorithm that is not bound by specific constraints such as time, space, or operational parameters. This might mean that the algorithm can perform any computation, regardless of its efficiency or resource consumption.
In grammar, a **predicate** is the part of a sentence or clause that describes what the subject does or what happens to the subject. It typically includes the verb and any objects or modifiers associated with that verb. Essentially, the predicate provides information about the subject, such as actions, states, or occurrences. For example, in the sentence: - "The cat (subject) sat on the mat (predicate).
An arbitrary unit (AU) is a unit of measurement that is defined not by a universal standard, but rather within the context of a specific experiment or system. In scientific and engineering applications, arbitrary units are often used when it is more meaningful to express values relative to one another rather than in absolute terms. This can occur in fields such as physics, signal processing, and various branches of research where the focus is more on comparisons or trends rather than exact measurements.
An arcade cabinet is a specialized piece of gaming hardware that houses an arcade game, which is typically a coin-operated video game. These cabinets are found in arcades, amusement parks, and other entertainment venues. Here are some key features of arcade cabinets: 1. **Design**: Arcade cabinets usually have a distinctive design, often incorporating colorful artwork that reflects the game’s theme. The cabinets can vary in size and shape, including upright cabinets, cocktail tables, and sit-down models.
Architonnerre is a French architectural movement and artistic approach that focuses on integrating earth and natural materials into construction. The term combines "archi," which relates to architecture, and "tonnerre," meaning thunder in French, suggesting a powerful or impactful way of shaping architectural practices. The movement emphasizes sustainability, ecological awareness, and the use of local materials. It often advocates for homes and structures that are not only environmentally friendly but also harmoniously blended with their surroundings.
An amortization calculator is a financial tool that helps users determine the breakdown of loan payments over time. It calculates how much of each payment goes toward paying off the principal (the original sum borrowed) and how much goes toward interest. This is particularly useful for loans that have a fixed repayment schedule, such as mortgages, auto loans, or personal loans. Here’s how an amortization calculator typically works: 1. **Loan Amount**: The total amount of money borrowed.
Arias intensity is a metric used in seismology to quantify the severity of ground shaking during an earthquake. It is defined as the integral of the square of the acceleration of ground motion over time, scaled by a factor to reflect the earthquake's impact. This measure is particularly useful because it accounts for both the amplitude and the duration of shaking, providing a better representation of the potential damage an earthquake can cause to structures and infrastructure.
Aristaeus the Elder is a figure from Greek mythology. He is often associated with agriculture, animal husbandry, and various aspects of rural life. Aristaeus was considered a pastoral deity and is sometimes linked to the practice of beekeeping, olive cultivation, and the protection of livestock. In some myths, he is described as the son of Apollo and the nymph Cyrene, and his role is often that of a teacher or benefactor of mankind, imparting essential agricultural knowledge.
Aristotelian physics is the natural philosophy developed by the ancient Greek philosopher Aristotle in the 4th century BCE. It encompasses his ideas about the nature of physical objects, their motion, and the principles governing the natural world. Aristotle's approach was largely qualitative and descriptive rather than quantitative and mathematical, which contrasted with later developments in physics, particularly during the Scientific Revolution.
