Nucleus sampling
Nucleus sampling, also called top-p sampling, is a language model decoding method that samples from the smallest set of top tokens whose probabilities sum to p.
Nucleus-Image
Nucleus-Image is a 17B-parameter open-source text-to-image diffusion model using a sparse mixture-of-experts architecture, released by NucleusAI on April 14, 2026 under Apache 2.0, activating roughly 2B parameters per generation.
Nucor
Nucor Corporation is an American steelmaker headquartered in Charlotte, North Carolina. It pioneered the mini-mill model and makes roughly a quarter of all raw steel in the United States.
Nuctech
Nuctech, or 同方威视, is a Chinese security inspection manufacturer in Beijing, founded in 1997 as a Tsinghua University spin-off and a leading supplier of container X-ray scanners.
Nuestra Señora de Atocha
Nuestra Señora de Atocha was a Spanish treasure galleon that sank in a hurricane off Key West in 1622 and was rediscovered by Mel Fisher in 1985.
Nuestra Señora de las Mercedes (ship)
Nuestra Señora de las Mercedes was a Spanish Navy frigate built at Havana in 1788 and sunk by a British squadron off Cádiz in 1804.
Nuevo Laredo
Nuevo Laredo is a city in Tamaulipas, Mexico, across the Rio Grande from Laredo, Texas. Founded in 1848, it anchors the busiest commercial crossing on the US–Mexico border.
Nuevo Teapa-Salina Cruz Oil Pipeline
The Nuevo Teapa-Salina Cruz Oil Pipeline is a pair of Pemex crude pipelines in southern Mexico running 267 km from Veracruz to the Salina Cruz refinery in Oaxaca.
Nuevo Teapa-Tula Oil Pipeline
The Nuevo Teapa-Tula Oil Pipeline is a Pemex crude oil pipeline in Mexico running from Veracruz to the Tula refinery in Hidalgo, operating since 1981.
NuGet
NuGet is the package manager for .NET, defining how packages are created, hosted, and consumed, with nuget.org as its central public repository and support for private hosts.
Nulato, Alaska
Nulato is a small city of 239 people on the west bank of the Yukon River in western Alaska, largely Koyukon Athabascan and incorporated in 1963.
Null (SQL)
Null (SQL), often written NULL, is a special marker for a missing or inapplicable value, introduced by Edgar F. Codd, distinct from zero and the empty string.
Null character
The null character, abbreviated NUL and written '\0' in C, is a control character with all bits of its encoding set to zero, used to terminate C strings.
Null modem
A null modem is a serial cable or adapter that crosses the transmit and receive lines of RS-232 devices, letting two computers connect directly without modems.
Null semantics
Null semantics are the rules SQL uses to handle null, a placeholder for unknown or missing values, evaluating comparisons under three-valued logic whose truth values are true, false, and unknown.
Null steering
Null steering is an antenna array technique that adjusts the radiation pattern to place deep minima, called nulls, toward unwanted signals while receiving the desired signal, used in radar, sonar, and communications.
Null-space impedance control
Null-space impedance control is a robot control technique giving a redundant manipulator's unneeded joints compliant spring-damper behavior, so its body yields safely to physical contact while the end-effector task continues.
Null-space projection
Null-space projection is a control technique for redundant robots in which lower-priority commands are projected so they cannot interfere with higher-priority tasks like end-effector tracking.
Number Nine Revolution
The Number Nine Revolution was a line of high-end graphics cards made by Number Nine Visual Technology, culminating in the Revolution 3D of 1997 and Revolution IV of 1998.
Number One Electronic Switching System
The Number One Electronic Switching System, or No. 1 ESS, was the Bell System's first electronic switching system, a computer-controlled telephone exchange first serving Succasunna, New Jersey, in 1965.
Number-average molecular weight
The number-average molecular weight, or number-average molar mass (Mn), is a polymer sample's total mass divided by its total number of chains, so each chain counts equally.
Numbered highways in the United States
Numbered highways in the United States are road routes identified by numbers rather than names, with the U.S. numbered system adopted in 1926 and Interstate numbering deliberately reversing its grid.
Numbering relief, overlays and number conservation
Numbering relief, overlays, and number conservation are the mechanisms that keep a telephone numbering plan from running out of assignable numbers, chiefly area code splits, overlays, and pooling.
Numbi Oil and Gas Field
The Numbi Oil and Gas Field is a Chevron-operated offshore oil field in Block 0 off Cabinda, Angola, part of the Greater Takula Area and producing since 1972.
Numeric keypad
A numeric keypad, also called a number pad or tenkey, is a compact block of keys for entering digits and arithmetic operators, on telephones and the right side of computer keyboards.
Numerical control
Numerical control (NC) is programmable automation of machine tools by coded numbers, originally on punched paper tape, first demonstrated at MIT in 1952; computer-based versions are called CNC.
Numerical differentiation
Numerical differentiation is the set of methods for estimating a function's derivative from sampled values using finite differences, balancing truncation error and floating-point round-off through the choice of step size.
Numerical inverse kinematics
Numerical inverse kinematics is the family of iterative methods that find robot joint configurations placing the end-effector at a desired pose, used when no analytic solution exists.
Numerical manifold method
The numerical manifold method (NMM), proposed by Gen-hua Shi in 1991, is a numerical technique for computing the deformation of solids containing cracks, joints, and block boundaries.
Numero Verde
Numero Verde, Italian for "green number," is Italy's toll-free telephone service with nine-digit 800 numbers that are free to call, regulated by AGCOM and paid entirely by the called party.
