Dc is a reverse Polish notation (RPN) calculator that is part of the standard GNU core utilities. It stands for "desk calculator" and is designed for performing arbitrary-precision arithmetic operations. Unlike traditional calculators that use infix notation (like 2 + 2), dc uses postfix notation, where operators follow their operands. **Key features of dc include:** 1.

Determiner spreading is a linguistic phenomenon observed in some languages, particularly in certain West African languages, where determiners (words that introduce nouns and provide information about their definiteness, quantity, etc.) can appear in a repeated or spread-out form. Instead of a single determiner introducing a noun phrase, multiple determiners can be used in conjunction with a noun or noun phrase.

Demonic non-determinism is a concept from the field of formal methods and theoretical computer science, particularly in the context of programming languages and semantics. It refers to a type of non-determinism in which the behavior of a program can be influenced by some external, adversarial control, often thought of as a "demon" that chooses paths or outcomes in a non-deterministic manner.

"Quicksilver" is a historical novel written by Neal Stephenson, published in 2003. It is the first book in his "Baroque Cycle," a trilogy that also includes "The Confusion" and "The System of the World." The novel is set in the late 17th and early 18th centuries and intertwines various real historical events and figures with fictional characters and plots.

Desorption is the process by which a substance, typically a gas or liquid, is released from or is no longer adherent to a solid surface. It is the opposite of adsorption, where molecules adhere to a surface. Desorption can occur due to various factors, such as changes in temperature, pressure, or concentration. In environmental science, desorption is significant in understanding pollutant release from soils or sediments.

Detection theory, often referred to as signal detection theory (SDT), is a framework used to understand how decisions are made under conditions of uncertainty. It is particularly relevant in fields like psychology, neuroscience, telecommunications, and various areas of engineering. ### Key Concepts of Detection Theory: 1. **Signal and Noise**: At its core, detection theory distinguishes between "signal" (the meaningful information or stimulus) and "noise" (the irrelevant information or background interference).

Yelpidifor Kirillov, also known as Yelpidifor Kirillovich Kirillov, is a relatively obscure figure and is most commonly associated with works of Russian literature, particularly in the context of discussions about the 19th-century philosophical and literary movements.

Diffusion is a physical process that describes the movement of particles from an area of higher concentration to an area of lower concentration. This movement occurs due to the random thermal motion of particles and continues until equilibrium is reached, meaning that the concentration of particles is uniform throughout a given space. Diffusion can occur in various states of matter, including gases, liquids, and solids.

In the context of vector spaces in linear algebra, the **dimension** of a vector space is defined as the number of vectors in a basis of that vector space. A basis is a set of vectors that is both linearly independent and spans the vector space.

The Dirichlet beta function, denoted as \( \beta(s) \), is a special function that generalizes the concept of the Riemann zeta function.

Distortion synthesis is a sound synthesis technique that generates audio by applying distortion effects to a signal. It achieves a rich, complex sound by intentionally altering the harmonic structure of an audio waveform through various distortion processes. Distortion synthesis can produce a wide range of tones, from subtle warmth to aggressive, gritty textures, making it popular in genres like rock, electronic, and experimental music.

Seasteading is the concept of creating permanent, autonomous communities on the ocean, typically in floating or semi-submerged structures. The term combines "sea" and "homesteading," reflecting the idea of establishing new societies in uncharted, oceanic territories, away from the constraints of existing governmental and legal systems. Proponents of seasteading often envision these floating communities as innovative, self-governing entities that experiment with new forms of governance, social structures, and technologies.

Autonomous buildings refer to structures that can operate independently and efficiently, often incorporating advanced technologies like artificial intelligence, the Internet of Things (IoT), and renewable energy sources. These buildings are designed to manage their own energy use, climate control, lighting, security, and other operational aspects with minimal human intervention. Key characteristics of autonomous buildings include: 1. **Energy Self-Sufficiency**: They often utilize renewable energy sources, such as solar panels or wind turbines, to generate their own electricity.

Lunar resources refer to the materials and elements that can be found on the Moon, which have the potential for extraction and utilization for various purposes. These resources are of significant interest for both scientific research and the support of future lunar exploration and colonization efforts. Some of the key lunar resources include: 1. **Water Ice**: Found primarily in permanently shadowed craters at the lunar poles, water ice can be extracted and used for drinking, as well as for producing oxygen and hydrogen for fuel.

A double planetoid is a celestial body that consists of two objects that are gravitationally bound to each other, typically of similar size. These objects orbit around their common center of mass, which is located outside of either object if they are of comparable size. Double planetoids can also be considered a subtype of binary systems, specifically in the category of small Solar System bodies such as asteroids or Kuiper Belt objects.

Domino tiling is a mathematical concept that involves covering a given area (usually a rectangular region) with dominoes, where a domino is a rectangular piece that covers two adjacent unit squares. In the context of combinatorial mathematics and theoretical computer science, domino tilings are often explored in relation to various problems such as counting configurations, studying combinatorial effects, and examining properties of different types of grids.

Dorothy P. Rice is a notable figure in the field of public health and epidemiology, particularly recognized for her contributions to health statistics and research methods. She is known for her work on health disparities, particularly those affecting older adults, and has played a significant role in advancing our understanding of health data collection and analysis. Her research often focuses on topics like the aging process, access to healthcare, and the social determinants of health.

Douglas 2229 refers to a specific genetic mutation in the *Drosophila melanogaster* species, commonly known as the fruit fly. It is notable for its association with certain phenotypic characteristics, particularly in the context of research related to genetics and developmental biology. The designation "Douglas" often denotes the name of the researcher or lab associated with the discovery or study of this mutation.
