Latte Line
The latte line is Sydney's informal socioeconomic boundary separating the affluent north-east from the less affluent south-west, running roughly from Sydney Airport past Parramatta; variants include the Red Rooster Line and Quinoa Curtain.
Latte macchiato
Latte macchiato, Italian for "stained milk," is an espresso-milk drink built milk-first with espresso poured through foam, forming three layers via double-diffusive convection; distinct from latte, cappuccino, and espresso macchiato.
Latter Day Church of Christ
Latter Day Church of Christ, also called the Kingston Group, Kingston Clan, Davis County Cooperative Society, or the Order: a Mormon fundamentalist polygamous sect founded in 1935 in Bountiful, Utah, by Charles Elden Kingston, unaffiliated with the LDS Church and led by Paul Elden Kingston.
Latter Day Saint movement
The Latter Day Saint movement, also known as the Mormon or LDS movement, is a restorationist Christian movement begun by Joseph Smith, who organized its first church in 1830.
Latter Rain (post–World War II movement)
The Latter Rain movement, also called Manifest Sons of God, was a Pentecostal revival begun in 1948 in Saskatchewan, teaching that God was restoring apostles, prophets, and spiritual gifts.
Lattice (group)
A lattice, or point lattice, is a discrete additive subgroup of Euclidean space, a periodic set of points central to the geometry of numbers, sphere packings, and cryptography.
Lattice (order)
A lattice is a partially ordered set in which every pair of elements has a greatest lower bound (meet) and a least upper bound (join).
Lattice Boltzmann methods
Lattice Boltzmann methods (LBM) are numerical techniques for computational fluid dynamics that simulate fluid flow on a lattice, well suited to complex geometries and multiphase interfaces.
Lattice Boltzmann simulation
A lattice Boltzmann simulation is a computational fluid dynamics method that tracks particle distributions on a discrete lattice, producing density, velocity, and pressure fields for fluid flows.
Lattice constant
The lattice constant, also called the lattice parameter, is one of six lengths and angles specifying a crystal's unit cell, typically measured by X-ray diffraction in ångströms.
Lattice corneal dystrophy type I
Lattice corneal dystrophy type I (LCD1, Biber-Haab-Dimmer, classic lattice corneal dystrophy) is a rare autosomal dominant TGFBI (5q31, R124C) amyloid stromal corneal dystrophy causing lattice lines, erosions, and vision loss from the first decade, treated with PTK or keratoplasty.
Lattice energy
Lattice energy, also called lattice enthalpy, measures how strongly ions are held in an ionic crystal; it is obtained from Born-Haber cycles and grows with ionic charge.
Lattice equalizer
A lattice equalizer is an adaptive channel equalizer built from a cascade of lattice stages with reflection coefficients rather than a tapped delay line, which lets it converge faster and track time-varying channels.
Lattice field theory
Lattice field theory, also called lattice regularization, formulates a quantum field theory on a discrete space-time grid, with lattice QCD, proposed by Kenneth Wilson in 1974, its principal application.
Lattice filter
A lattice filter is a digital filter structure built from identical cascaded stages, each defined by one reflection coefficient, used in speech processing and adaptive filtering.
Lattice gas model
The lattice gas model is a statistical-mechanical and fluid-dynamical model in which particles occupy only discrete lattice sites, first named by Yang and Lee in 1952.
Lattice gauge theory
Lattice gauge theory, introduced by Kenneth Wilson in 1974, defines gauge field theories like quantum chromodynamics on a discrete spacetime lattice, allowing non-perturbative calculations by numerical simulation.
Lattice light-sheet microscopy
Lattice light-sheet microscopy is a fluorescence microscopy method that images living cells in 3D using an ultrathin light sheet, with far less phototoxicity than confocal microscopy.
Lattice metamaterials
Lattice metamaterials are artificial cellular materials built from a periodic arrangement of struts, plates, or shells, with mechanical properties set by unit cell geometry rather than base material composition.
Lattice model (finance)
A lattice model in finance values an option on a tree of possible price paths, working backward from payoffs at maturity; the best-known form is the 1979 Cox–Ross–Rubinstein binomial model.
Lattice oxygen mechanism
The lattice oxygen mechanism (LOM), also called lattice oxygen evolution reaction, is an oxygen evolution pathway where catalyst lattice oxygen directly forms O2, bypassing adsorbate mechanism limits.
Lattice physics calculation
A lattice physics calculation is a neutron transport and fuel depletion computation on a 2D fuel assembly slice, producing few-group cross sections for full-core reactor simulation.
Lattice QCD
Lattice QCD, also known as lattice quantum chromodynamics, is the formulation of QCD, the theory of the strong interaction, on a discrete space-time grid, proposed by Kenneth Wilson in 1974.
Lattice Semiconductor
Lattice Semiconductor is an American semiconductor company in Hillsboro, Oregon, founded in 1983, that designs low-power field-programmable gate arrays and is the last major FPGA maker still independent.
Lattice surgery
Lattice surgery is a fault-tolerant method for performing logical operations between surface-code quantum memories by merging and splitting code lattices, introduced in 2012 as an alternative to defect braiding.
Lattice tower
A lattice tower is a tall, free-standing steel truss framework used chiefly to support overhead power lines and telecommunications antennas, its open lattice letting wind pass through.
Lattice units
Lattice units are the dimensionless units in which lattice QCD simulations express results, with masses given in units of the lattice spacing a; converting to physical units requires scale setting.
Lattice-based cryptography
Lattice-based cryptography (lattice cryptography) is public-key cryptography whose security rests on hard lattice problems, making it resistant to quantum computer attacks; NIST standardized ML-KEM and ML-DSA in 2024.
Lattice-ordered group
A lattice-ordered group, also called an ℓ-group, is a group with a partial order under which every two elements have a meet and join, preserved by all translations.
Lattice-reduction-aided detection
Lattice-reduction-aided detection is a MIMO receiver technique that transforms the channel matrix into a nearly orthogonal basis, letting simple detectors approach maximum-likelihood performance at low complexity.
