Localization microscopy
Localization microscopy, also called single-molecule localization microscopy (SMLM), is a fluorescence microscopy technique that reconstructs super-resolution images by pinpointing individual fluorescent molecules, reaching resolutions near 10–30 nm.
Localized epidermolysis bullosa simplex
Localized epidermolysis bullosa simplex (EBS-loc, formerly Weber-Cockayne) is the mildest, most common EBS subtype (about 60% of cases), an autosomal dominant KRT5/KRT14 disorder causing palmoplantar blisters triggered by friction and heat, treated supportively.
Localized high-concentration electrolyte
A localized high-concentration electrolyte is a battery electrolyte made by diluting a concentrated lithium-salt electrolyte with a non-coordinating diluent, preserving concentrated-electrolyte interfacial chemistry at lower viscosity and cost.
Localized intravascular coagulation
Localized intravascular coagulation (LIC), also called localized intravascular coagulopathy, is a consumptive coagulopathy confined to a vascular lesion, occurring chiefly in venous malformations and marked by elevated D-dimer.
Localized junctional epidermolysis bullosa
Localized junctional epidermolysis bullosa is a mild subtype of junctional epidermolysis bullosa, an inherited blistering skin disease present from birth and confined mainly to the hands, feet, and face.
Localized pagetoid reticulosis
Localized pagetoid reticulosis, or Woringer-Kolopp disease, is a rare indolent variant of mycosis fungoides: a solitary hyperkeratotic or psoriasiform plaque, usually on one extremity, treated with radiotherapy or excision, with no reported disease-related deaths.
Localized surface plasmon resonance
Localized surface plasmon resonance (LSPR) is the collective oscillation of conduction electrons in metallic nanoparticles, producing strong absorption and scattering peaks used for sensing, surface-enhanced Raman spectroscopy, and photothermal catalysis.
Localizer Performance with Vertical Guidance
Localizer Performance with Vertical Guidance (LPV) is a GPS-based instrument approach using WAAS, flown like an ILS to a decision altitude as low as 200 feet.
Locally compact group
A locally compact group, also called a locally compact topological group, is a topological group where every point has a compact neighborhood. It is the standard setting for Haar measure and harmonic analysis.
Locally compact space
A locally compact space is a Hausdorff topological space where every point has a compact neighborhood, a weakening of compactness exemplified by Euclidean space Rn.
Locally convex topological vector space
A locally convex space (LCS) is a topological vector space whose topology is generated by a family of seminorms, the standard setting for duality theory in functional analysis.
Locally linear embedding
Locally linear embedding (LLE) is an unsupervised algorithm for nonlinear dimensionality reduction that maps high-dimensional data into a low-dimensional, neighborhood-preserving embedding, introduced by Roweis and Saul in 2000.
Locally listed building
A locally listed building is a building in England placed on a local heritage list by a local planning authority, a non-statutory designation covering assets of local heritage significance.
Locana
Locana (लोचन, "the Eye") is the Sanskrit commentary written by the Kashmiri philosopher Abhinavagupta on the Dhvanyāloka of Ānandavardhana, the ninth-century treatise establishing dhvani, or poetic suggestion.
Locanto
Locanto is a free local classifieds website operated by Yalwa GmbH, a German internet company founded in 2006 and based in Wiesbaden, with sites in more than 50 countries.
Locard's exchange principle
Locard's exchange principle, Edmond Locard's foundational forensic science maxim often paraphrased as 'every contact leaves a trace,' holds that contact between objects transfers material both ways, underpinning trace evidence, transfer and persistence research, and crime scene investigation.
Locarno Treaties
Locarno Treaties: seven 1925 agreements from the Locarno Conference (Oct 5-16, 1925), signed in London Dec 1, 1925; Rhineland Pact fixed Germany's western border, arbitration treaties covered Poland and Czechoslovakia, and Germany joined the League in 1926.
Location
Location: the position of a point on Earth's surface, absolute (latitude/longitude) or relative; also the device estimate phones produce from GPS, Wi-Fi, cellular, and Bluetooth signals, with measured accuracies from about 2 m to 967 m.
Location allocation model
A location allocation model is an operations research and facility-planning method that simultaneously chooses facility sites and assigns demand points to them, minimizing demand-weighted distance or cost.
Location area
A location area (LA) is a group of adjacent radio cells in a GSM or UMTS cellular network within which the network knows a mobile phone's approximate position.
Location hypotheses of Atlantis
Location hypotheses of Atlantis are the proposed identifications of Plato's island power with real places, tested against his account of a site beyond the Pillars of Heracles that sank around 9,000 years before his time.
Location identifier
A location identifier is a short code, usually three or four letters, standing in for an airport or facility in reservations, air traffic control, and weather reporting.
Location test
A location test is a statistical hypothesis test that compares the location parameter, such as the mean or median, of distributions, using parametric tests like the t-test or nonparametric rank tests.
LOCATION trial
LOCATION trial (NCT07388030), a 2x2 factorial randomized trial in China comparing intravascular lithotripsy versus balloon angioplasty and OCT- versus angiography-guided stenting in 3,060 patients with severely calcified coronary lesions; primary endpoint 3-year target vessel failure.
Locational marginal price
The locational marginal price (LMP) is the wholesale price of electric energy at a specific grid location, comprising energy, congestion, and loss components, used by RTOs and ISOs since 1998.
Locations in the United States with an English name
US populated places and counties named for English places or English words, such as Boston (from Boston, Lincolnshire) and Hartford (from Hertford); GNIS records, New England density, and cross-state clusters like Springfield.
Locations of Genshin Impact
Locations of Genshin Impact: the explorable areas of Teyvat, spanning seven main nations (Mondstadt through Snezhnaya, the last, opened August 2026) plus autonomous Nod-Krai, its subregions, and the official and community interactive maps.
LOCC
LOCC, or local operations and classical communication, is the class of operations in quantum information theory where separated parties act locally and exchange classical messages.
Loch Henry
Loch Henry is the second episode of Black Mirror season 6 (2023), written by Charlie Brooker and directed by Sam Miller. Set in a fictional Scottish town, it satirizes true crime documentaries as filmmakers Davis and Pia uncover that the Iain Adair murders were committed by Davis's parents.
Loch Lomond
Loch Lomond, a glacial freshwater loch in southern Scotland, is Scotland's largest loch by surface area at 71 km2, has deep northern and shallow southern basins, and anchors Loch Lomond & The Trossachs National Park, Scotland's first national park (2002).
