Expiratory muscle strength training

Expiratory muscle strength training (EMST) is a rehabilitation technique in which patients exhale against a handheld pressure device to strengthen cough, swallowing, and breathing muscles.

Expiratory Reserve Volume

Expiratory reserve volume (ERV) is the maximal air exhaled from functional residual capacity to residual volume; one of four lung volumes, spirometry-measured, and reduced earliest and most markedly in obesity, supine posture, and pregnancy.

Explainable artificial intelligence

Explainable artificial intelligence (XAI), also called interpretable AI, comprises methods for making machine-learning models understandable, either by design or through post-hoc explanations of black-box systems.

Explained (TV series)

Explained is a Vox Media and Netflix documentary series (2018-2021, 3 seasons, 44 short episodes) created by Ezra Klein, with spin-offs The Mind, Explained and Coronavirus, Explained.

Explainer

Explainer, born Winston Henry (1947–2022), was a Trinidadian calypsonian known for "Lorraine", a Top 20 calypso of the 20th century that reached number 35 on the British charts.

Explanation

Explanation, in philosophy of science, is an answer to a why-question rather than mere description. Central models include Hempel's deductive-nomological account, Salmon's causal-mechanical theories, unificationism, and van Fraassen's pragmatic view.

Explanatory sequential mixed methods design

The explanatory sequential mixed methods design is a two-phase research design in which quantitative data are collected first and qualitative data are collected second to explain the quantitative results.

Explanatory trial

An explanatory trial is a randomized controlled trial testing whether an intervention works under ideal, tightly controlled conditions, a concept introduced by Schwartz and Lellouch in 1967.

Explant culture

Explant culture is a cell culture method in which a tissue fragment is placed in growth medium, either to derive primary cells or to preserve tissue architecture.

Explantation

Explantation is the surgical removal of an implanted device, prosthesis, or transplanted tissue from the body, most often to treat infected cardiac device leads or remove breast implants.

Expleo

Expleo is a global engineering, technology, and consulting service provider headquartered in Montigny-le-Bretonneux, France, with about 17,000 experts in 29 countries; it was spun off from Assystem in 2017 and renamed Expleo in 2019.

Explicit and implicit methods

Explicit and implicit methods are the two families of time-stepping schemes for numerically integrating ODEs and PDEs: explicit steps are cheap but step-size limited, implicit steps cost more but stay stable.

Explicit congestion notification

Explicit congestion notification (ECN) is an extension to IP and TCP in which a congested router marks packets instead of dropping them, standardized in RFC 3168 in 2001.

Explicit force control

Explicit force control, also called direct force control, is a robot control strategy in which a feedback loop acts directly on measured contact forces to hold a desired force.

Explicit formulae (L-function)

An explicit formula for an L-function is an identity in analytic number theory expressing a sum over the L-function's nontrivial zeros as a sum over prime powers.

Explicit model predictive control

Explicit model predictive control, or explicit MPC, precomputes the optimal control law offline as a piecewise affine function of the state, replacing online optimization with a fast region lookup.

Explicit time integration

Explicit time integration is a class of numerical methods that advance time-dependent differential equations step by step using only known values, favored for crash and shock simulation.

Explicitly correlated F12 methods

Explicitly correlated F12 methods are quantum-chemistry methods that add terms depending explicitly on interelectronic distance r12, so triple-zeta basis sets reach near complete-basis-set accuracy at small extra cost.

Exploding head syndrome

Exploding head syndrome (EHS), also called episodic cranial sensory shock, is a benign parasomnia of sudden painless loud noises at sleep-wake transitions, first described in 1876, with variable prevalence and reassurance-based management.

Exploding Kittens

Exploding Kittens is a card game by Matthew Inman, Elan Lee, and Shane Small where drawing an Exploding Kitten card eliminates you unless you hold a Defuse.

Exploding Kittens (TV series)

Exploding Kittens is Netflix's 2024 adult animated comedy adapted from the Exploding Kittens card game, starring Tom Ellis and Sasheer Zamata as Godcat and Devilcat, created by Matthew Inman and Shane Kosakowski.

Exploding Plastic Inevitable

Exploding Plastic Inevitable (EPI), also staged as Andy Warhol Up-Tight, was Warhol and Paul Morrissey's 1966–67 multimedia show at The Dom and on US tour, pairing the Velvet Underground and Nico with films, strobes, slides, and Factory dancers.

Exploding whale

Exploding whale: a decomposing whale carcass that bursts from trapped decomposition gases, or is deliberately detonated. Famous cases: Florence, Oregon 1970 half-ton dynamite blast and the 2004 Tainan, Taiwan sperm whale street explosion.

Exploding-bridgewire detonator

An exploding-bridgewire detonator, or EBW, is an initiator that fires secondary explosive with an electrical pulse, invented at Los Alamos for the Fat Man bomb.

Exploit (computer security)

An exploit, also known as a security exploit, is software or a technique that takes advantage of a vulnerability in a computer system to bypass its security policy.

Exploitation film

Exploitation film, also called exploitation cinema, refers to low-budget films made for quick profit by exploiting topical anxieties and taboo subjects like sex, violence, and drug use.

Exploitation of labour

Exploitation of labour: unfair advantage taken of workers, from sub-value wages to forced labor. Marx measured it as surplus value over variable capital (S/V); ILO counts 27.6 million in forced labor producing $236 billion in illegal profits.

Exploitation of natural resources

Exploitation of natural resources, also called resource exploitation, is the removal of environmental resources from their natural position for economic growth, ranging from ordinary use to overexploitation.

ExploitGym

ExploitGym is a publicly released benchmark of 898 real-world software exploitation tasks, built by academic and industry researchers to test whether AI agents can turn known vulnerabilities into working attacks.
