Pullip is a type of doll that originated in South Korea. It was first introduced by the company Cheonsang Cheonha in 2003. Pullip dolls are characterized by their large heads, expressive eyes, and the ability to change eyes and make various facial expressions. They are typically made of plastic and have articulated bodies, allowing for a wide range of poses. Each Pullip doll has a unique design, often inspired by various themes such as fashion, fantasy, or anime.

Metafont is a font definition language and a system developed by Donald Knuth as part of his TeX typesetting system. Introduced in the late 1970s, Metafont is primarily used to define and create bitmap fonts based on mathematical equations and descriptions. Unlike traditional font design, where fonts are typically created using graphical design tools, Metafont allows designers to specify a font's characteristics through a programming-like syntax.

LOGCFL is a complexity class that stands for "Logarithmic Space Context-Free Languages." It is a subclass of context-free languages that can be recognized by a deterministic pushdown automaton operating in logarithmic space. More formally, a language is in LOGCFL if it can be decided by a deterministic Turing machine that uses logarithmic space and is able to make use of a stack, like a pushdown automaton.

NGC 6357 is an open cluster and stellar nursery located in the constellation Scorpius. It is part of a larger molecular cloud complex known as the "Cats Paw Nebula," which is rich in star formation activity. NGC 6357 contains several bright stars and is surrounded by a region of ionized gas and dust, which is illuminated by the high-energy radiation emitted by the young, massive stars within the cluster.

Promethium is a chemical element with the symbol Pm and atomic number 61. It is part of the lanthanide series of the periodic table. Promethium is one of the rarest elements on Earth and is radioactive, with no stable isotopes. Its most common isotopes are promethium-145 and promethium-147. Promethium does not occur naturally in significant quantities; it was discovered in 1945 by chemists Glenn T.

A goniometer is an instrument used to measure angles or to assess the range of motion in joints. It is commonly employed in fields such as physical therapy, orthopedics, and sports medicine to evaluate joint flexibility and to document changes in range of motion over time. There are several types of goniometers: 1. **Universal Goniometer**: This is a common type that has two arms and a protractor-like scale in the center.

Surface energy is a fundamental concept in materials science and physics that refers to the excess energy at the surface of a material compared to its bulk. It arises due to the disruption of intermolecular bonds at the surface of a solid or liquid, as the molecules at the surface are not surrounded by similar molecules on all sides. This results in a higher energy state for surface molecules. In practical terms, surface energy affects various properties, such as wetting, adhesion, and adsorption.

The Tupolev Tu-144 is a supersonic transport aircraft developed by the Soviet Union, known for being one of the first supersonic passenger planes to enter service. Its development began in the late 1960s, and the aircraft made its first flight on December 31, 1968, just a few months before the British-French Concorde.

The USNS Sampan Hitch (T-AKR-314) is a vehicle cargo ship that is part of the United States Navy's Military Sealift Command. It is designed to transport military equipment, vehicles, and supplies, primarily to support U.S. military operations. Like other ships in the Navy's roll-on/roll-off (RORO) fleet, the Sampan Hitch is equipped to carry a variety of wheeled and tracked vehicles, ensuring rapid transport and deployment as required by military logistics.

Frenchelon is a term used to describe the French government's electronic surveillance program, which is part of its broader national security and intelligence efforts. It involves the monitoring and collection of communications data, including phone calls, emails, and internet activity, both domestically and from foreign sources. Frenchelon is similar in concept to other national surveillance programs like the NSA's activities in the United States, particularly in the context of counter-terrorism and intelligence gathering.

A minot is a non-SI unit of measure used to quantify luminous flux. Specifically, it is defined as the luminous flux emitted in a solid angle of one steradian by a point source that has a luminous intensity of one candela. In practical terms, one minot is equal to one lumen per steradian (1 minot = 1 lumen/sr). This unit is not commonly used in modern lighting science, where the lumen and candela are more prevalent.

Carrie Everson is a professional known for her work in the field of marketing and advertising, particularly in leadership roles within major companies. As of my last knowledge update in October 2021, she was recognized for her contributions to brand strategy and growth, previously holding significant positions at companies like Nielsen and leading marketing initiatives in various industries.

Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) is a scientific instrument developed for the study of Mars, primarily onboard NASA's Perseverance rover, which was launched in July 2020 and landed on Mars in February 2021. SHERLOC's primary goal is to identify and characterize organic compounds and potential biosignatures—signs of past or present life—within Martian surface materials.

Quickselect is an efficient algorithm used to find the k-th smallest (or largest) element in an unordered list. It is related to the Quicksort sorting algorithm and uses a similar partitioning approach.

An "undervote" refers to a situation in an election where a voter does not select a candidate for a particular office on the ballot, even though they have cast a vote for other races or issues. This can occur for various reasons, such as a lack of preference for any of the candidates, confusion about the ballot, or overlooking that specific section of the ballot altogether. Undervotes can be significant in elections, as they may affect the outcome, particularly in close races.

A **locally constant function** is a type of function that is constant within a localized region of its domain.

Tsume shogi is a type of puzzle in shogi (Japanese chess) that focuses on finding a sequence of moves leading to checkmate. In tsume shogi, the problem typically presents a scenario where one player, the "shiro" (white) or "kuro" (black), must deliver checkmate in a specified number of moves, regardless of the opponent's responses. The puzzles vary in complexity and can involve different pieces and arrangements on the board.

Baseband refers to a communication method where the original signal is transmitted over a medium without modulation onto a carrier frequency. In simpler terms, baseband signals are the original signals that utilize the entire bandwidth of the communication medium to carry information. Baseband can apply to various contexts, including: 1. **Data Transmission**: In networking, baseband transmission means that the entire bandwidth of the medium (like a coaxial cable or twisted pair cable) is used for a single communication channel.

QuantLib is an open-source library for quantitative finance, primarily used for modeling, trading, and risk management in financial markets. It is written in C++ and provides a comprehensive suite of tools for quantitative analysis, including: - **Interest rate models**: Facilities for modeling and analyzing interest rate derivatives. - **Options pricing models**: Various methodologies for pricing different types of options, including European, American, and exotic options.

Paulius Saudargas is a Lithuanian politician who is a member of the Lithuanian Parliament (Seimas). He is known for his involvement in various political issues and has been associated with several political parties throughout his career.
