The luminal adaptive secretory precursor (LASP) cell of mammary gland is a hormone receptor-low, alveolar and secretory luminal epithelial cell type, corresponding to luminal progenitor cells in human single-cell omics.
Luminance
Luminance is the photometric measure of luminous intensity per unit projected area in a specified direction, measured in candelas per square meter, and the quantity most closely matching perceived brightness.

Luminescence
Luminescence is the spontaneous emission of light from an excited substance not in thermal equilibrium with its surroundings, distinct from incandescence; Eilhard Wiedemann coined the term in 1888.
Luminescence dating
Luminescence dating, also called optical dating, is a family of geochronological methods that date when quartz or feldspar grains were last exposed to sunlight or heat.
Luminescence imaging
Luminescence imaging is a camera-based technique that maps light emitted by a sample, typically after electrical or optical excitation, to reveal defects and material properties.
Luminescence spectroscopy
Luminescence spectroscopy measures the light a substance emits after excitation, using the emitted spectrum to characterize electronic states, defects, and composition in materials and molecules.
Luminescence thermometry
Luminescence thermometry is a contactless technique that reads temperature from temperature-dependent features of light emitted by phosphors or nanoparticles, mapping temperatures in microfluidics, nanomedicine, and strong electromagnetic fields.
Luminescent downshifting
Luminescent downshifting (LDS) is an optical technique for solar cells in which a luminescent layer absorbs UV and blue light and re-emits it where the cell converts more efficiently.
Luminescent solar concentrator
A luminescent solar concentrator is a photonic device, first proposed in 1976, that uses luminophore-doped plates to guide sunlight to edge-mounted photovoltaic cells, mainly for building windows.
Luminex xMAP technology
Luminex xMAP technology, short for Multi-Analyte Profiling, is a bead-based multiplexing platform developed by Luminex Corporation that measures many analytes simultaneously in a single sample.
Luminiferous aether
The luminiferous aether, also spelled ether, was the hypothetical medium in which light was thought to travel as waves, abandoned after Einstein's 1905 relativity made it undetectable.
Luminism
Luminism is a retrospective term for a mid-nineteenth-century American landscape painting style, flourishing roughly 1850 to 1875, characterized by realistic light, concealed brushstrokes, and a quiet mood.
Luminița Gheorghiu
Luminița Gheorghiu (1949–2021) was a Romanian stage and film actress, Bulandra Theatre member and Ion Cojar student, celebrated for Mioara in The Death of Mr. Lazarescu and the lead in Child's Pose.
Luminite
Luminite is the stage name of Thomas Brok, a Dutch DJ and producer of hardstyle and raw hardstyle, best known for the 2019 single 'Bass Criminal'.
Luminol
Luminol (5-amino-2,3-dihydro-1,4-phthalazinedione) is a chemiluminescent reagent that glows blue when oxidized in alkali with a catalyst; used in forensic blood detection since Specht 1937 and in clinical immunoassays.
Luminosity
Luminosity is the total energy a star emits per second at all wavelengths, an intrinsic property distinct from apparent brightness; for main-sequence stars it rises steeply with mass.
Luminosity distance
Luminosity distance is the distance assigned to an astronomical object by comparing its observed flux with its intrinsic luminosity; Type Ia supernovae and gravitational-wave standard sirens measure it to probe cosmic expansion.
Luminosity measurement in particle physics
Luminosity measurement in particle physics is the set of techniques by which collider experiments determine how many collisions occurred, enabling conversion of event rates into cross sections.
Luminous (model family)
Luminous was a family of large language models developed by the German company Aleph Alpha, released from April 2022 and positioned as a step toward Europe's AI sovereignty.
