ELARIS EM-I trial
ELARIS EM-I (M12-665, NCT01620528), AbbVie's phase 3 trial of elagolix 150 mg once daily and 200 mg twice daily versus placebo in 872 women with endometriosis-associated pain; pivotal for Orilissa approval.
ELARIS EM-II trial
ELARIS EM-II (NCT01931670), AbbVie phase 3 trial of elagolix (Orilissa) 150 mg once daily and 200 mg twice daily versus placebo for 6 months in 817 women with endometriosis-associated pain; both doses met dysmenorrhea and nonmenstrual pelvic pain endpoints.
Elasmobranchii
Elasmobranchii, the elasmobranchs or strap-gills, is the cartilaginous fish subclass of sharks, rays, skates, and sawfish, excluding chimaeras; cartilage skeletons, unfused upper jaws, exposed gill slits, and about 37% of species threatened.
Elasmosaurus
Elasmosaurus platyurus, named by Edward Drinker Cope in 1868, is a long-necked plesiosaur from the Campanian Western Interior Seaway of Kansas with 72 neck vertebrae and a neck over 6 m long; its reversed first reconstruction fueled the Bone Wars.
Elasmotherium
Elasmotherium, also called the Giant Unicorn, is an extinct genus of giant Eurasian rhinoceroses whose last species, the Siberian unicorn, survived until at least 39,000 years ago.
Elastase
Elastase: serine proteases that degrade elastin, including pancreatic elastase (digestive enzyme, basis of the fecal elastase-1 test for EPI) and neutrophil elastase (ELANE-encoded, AAT-inhibited, drug target in COPD and ARDS).
Elasti-Girl
Elasti-Girl, also published as Elasti-Woman, is DC Comics heroine Rita Farr, a founding Doom Patrol member created in 1963 who grows to gigantic or shrinks to microscopic size, distinct from Pixar's Elastigirl.
Elastic averaging
Elastic averaging is a precision-engineering alignment principle that joins two bodies through many compliant contact points whose errors average out under preload, in contrast to kinematic design.
Elastic band path modification
Elastic band path modification is a robot motion planning technique introduced by Sean Quinlan and Oussama Khatib in 1993, where a collision-free path deforms under artificial forces.
Elastic cloaking
Elastic cloaking is the design of a material shell that makes an object invisible to elastic waves, first demonstrated experimentally in a polymer plate in 2012.
Elastic collision
An elastic collision is a collision between bodies in which total kinetic energy is conserved alongside momentum, so no kinetic energy becomes heat or deformation.
Elastic energy
Elastic energy, or elastic potential energy, is the energy stored in an object when it is deformed, such as a stretched spring, and returned as work.
Elastic fiber
An elastic fiber, or elastic tissue, is an extracellular matrix bundle about 90% elastin that lets skin, lungs, blood vessels, and other vertebrate tissues stretch and recoil.
Elastic Heart
Elastic Heart is a 2013 Sia song featuring The Weeknd and Diplo from The Hunger Games: Catching Fire soundtrack, re-recorded solo for 1000 Forms of Fear; its 2015 Maddie Ziegler and Shia LaBeouf video drew controversy.
Elastic metamaterial
An elastic metamaterial is an engineered material that controls elastic wave propagation in solids using local resonances, creating band gaps at wavelengths far larger than its unit cell.
Elastic metasurfaces for mode conversion
Elastic metasurfaces for mode conversion are thin engineered surfaces of subwavelength unit cells that convert elastic waves between longitudinal and transverse modes, reaching near-perfect efficiency.
Elastic modulus
The elastic modulus, also called the modulus of elasticity, is the ratio of stress to strain in a deformed material, a stiffness measure in pascals; Young's, bulk, and shear moduli are its principal forms.
Elastic N.V.
Elastic N.V. is a software company that develops the Elastic Stack, built around the Elasticsearch search engine and Kibana, and sells it as Enterprise Search, Observability, and Security.
Elastic net regularization
Elastic net regularization, also known as the elastic net, is a regression method combining the lasso and ridge penalties, proposed by Hui Zou and Trevor Hastie at Stanford in 2005.
Elastic optical network
An elastic optical network (EON) is an optical transport network that allocates spectrum in small, variable-width frequency slots rather than fixed 50 or 100 GHz channels.
Elastic recoil detection
Elastic recoil detection, also called forward recoil scattering, is an ion beam analysis technique first reported in 1976 that measures light elements, especially hydrogen, in thin films.
Elastic scattering
Elastic scattering is a collision between particles in which the system's kinetic energy is conserved, so particles deflect or exchange momentum without exciting, ionizing, or creating anything new.
Elastic therapeutic tape
Elastic therapeutic tape, or kinesiology tape (Kinesio Tape, developed by Kenzo Kase in 1979), is a stretchy cotton adhesive tape used for pain, swelling, and sports support; systematic reviews find little benefit over sham tape.
Elastic training
Elastic training is a distributed machine learning technique where a training job adjusts its number of workers while running, shrinking when nodes fail and growing when capacity returns.
Elastic wave cloaking
Elastic wave cloaking uses engineered metamaterials to steer elastic waves, such as seismic and flexural waves, around a region so it remains undetected by the wave field.
Elastic weight consolidation
Elastic weight consolidation (EWC) is a continual learning algorithm introduced by James Kirkpatrick and colleagues at Google DeepMind in 2017 to overcome catastrophic forgetting in neural networks.
Elastic-rebound theory
Elastic-rebound theory explains earthquakes as the sudden release of elastic strain that builds up in rock around a locked fault, proposed by Harry Fielding Reid after the 1906 San Francisco earthquake.
Elastica
Elastica: English Britpop-era rock band formed in London in 1992 by Justine Frischmann and Justin Welch after leaving Suede; 1995 self-titled debut topped the UK chart, second album The Menace (2000), dissolved in 2001.
Elastica (album)
Elastica is the 1995 self-titled debut album by Britpop band Elastica (Justine Frischmann, Donna Matthews, Annie Holland, Justin Welch). Released 13 March 1995 on Deceptive/DGC, it topped the UK chart as the fastest-selling British debut, with singles Stutter, Line Up, Connection, Car Song, and Waking Up.
ElasticFusion
ElasticFusion is a real-time dense visual SLAM system that builds surfel-based 3D maps of rooms from RGB-D camera video, correcting drift by deforming the map itself.
