Event reconstruction

Event reconstruction is the set of algorithms that turns raw detector signals into particle tracks, energies, and identities; at the LHC it runs in real time inside the trigger.

Event study

An event study is a statistical method measuring how an event, such as an earnings announcement or regulatory change, affects an outcome, typically abnormal security returns.

Everett C. Olson

Everett C. Olson (1910–1993) was an American vertebrate paleontologist who worked at the University of Chicago and UCLA and identified the mid-Permian faunal crisis now called Olson's Extinction.

Everett L. Shock

Everett L. Shock is an American geochemist, a professor at Arizona State University since 2002, known for thermodynamic modeling of hydrothermal systems and the energetics of microbial metabolism.

Everette Lee DeGolyer (1886–1956) was an American petroleum geologist and geophysicist known as the father of American geophysics; he led Amerada Petroleum, located the Nash dome in 1924, and founded the consulting firm DeGolyer and MacNaughton.

Everolimus

Everolimus is a semisynthetic derivative of rapamycin that inhibits mTOR, used to prevent transplant rejection and treat cancers under the brand names Afinitor, Zortress, and Certican.

Evert Hoek

Evert Hoek (1933–2024) was a South African-trained rock mechanics engineer best known for the Hoek–Brown failure criterion and the Geological Strength Index, and a professor at Imperial College and Toronto.

Evert Jan Baerends

Evert Jan Baerends, born 1945, is a Dutch theoretical chemist and professor emeritus at the Vrije Universiteit Amsterdam, known for density functional theory and the ADF program.

Evert Verwey

Evert Verwey (1905–1981) was a Dutch chemist who spent his career at the Philips Natuurkundig Laboratorium in Eindhoven and discovered the Verwey transition in magnetite in 1939.

Everyday sadism

Everyday sadism is a personality trait marked by enjoyment of others' pain or humiliation in ordinary settings, and the fourth trait of the Dark Tetrad.

Evgenii Landis

Evgenii Mikhailovich Landis (Евгений Михайлович Ландис) was a Soviet mathematician and professor at Moscow State University who worked on partial differential equations and co-invented the AVL tree in 1962.

Evgenii V. Kondratenko

Evgenii V. Kondratenko is a German-based heterogeneous catalysis researcher who heads the department Methods for Applied Catalysis at LIKAT in Rostock, and is known for propane dehydrogenation research.

Evgeny Golod

Evgeny Golod (Evgenii Solomonovich Golod, 1935–2018) was a Soviet and Russian algebraist at Moscow State University whose 1964 Golod–Shafarevich theorem solved the class field tower problem negatively.

Evgeny Lifshitz

Evgeny Lifshitz (Евгений Михайлович Лифшиц; 1915–1985) was a Soviet theoretical physicist who co-created the Course of Theoretical Physics with Lev Landau and developed Lifshitz theory of molecular forces.

Evgeny Y. Tsymbal

Evgeny Y. Tsymbal is a computational materials physicist and professor at the University of Nebraska–Lincoln who uses first-principles calculations to predict electronic, magnetic, and ferroelectric properties of nanoscale structures.

Evgeny Yakovlevich Remez

Evgeny Yakovlevich Remez (Євгеній Якович Ремез; 1896–1975) was a Soviet and Ukrainian mathematician in Kyiv who created the Remez exchange algorithm for Chebyshev approximation and the Remez inequality.

Evidence Gaps

Evidence gaps are topics on which impact evaluations and systematic reviews have produced scant or no evidence, a definition added to the MeSH vocabulary in 2023.

Evidence lower bound

The evidence lower bound (ELBO), also called the variational lower bound, is a computable lower bound on a model's log evidence, maximized in variational inference.

Evidence mapping

Evidence mapping is a systematic review method that searches a broad field, classifies every relevant study against a pre-specified framework, and presents the evidence visually to reveal gaps.

Evidence-based practice

Evidence-based practice, also called evidence informed healthcare, is a decision-making approach combining research evidence, professional expertise, and patient values; it grew out of evidence-based medicine.

Evolution Mining

Evolution Mining is an Australian gold mining company headquartered in Sydney, formed in November 2011, with six mines across Australia and Canada and additional copper exposure.

Evolution of the Asian monsoon

The evolution of the Asian monsoon is its geological history over the past 55 million years, with onset ages debated from about 55 to 22 Ma.

Evolutionary concept analysis

Evolutionary concept analysis is a qualitative research method used mainly in nursing that analyzes how a concept appears in literature to clarify its attributes, antecedents, and consequences.

Evolutionary game theory

Evolutionary game theory applies game theory to evolving populations, treating payoffs as Darwinian fitness. Its central concept, the evolutionarily stable strategy, came from Maynard Smith and Price in 1973.

Evolutionary graph theory

Evolutionary graph theory is a branch of mathematical biology studying how the graph structure of a finite population changes evolutionary dynamics, introduced by Lieberman, Hauert, and Nowak in 2005.

Evolved gas analysis

Evolved gas analysis (EGA) is an analytical technique that identifies and measures volatile products released when a substance is heated under a controlled temperature program.

Ewald summation

Ewald summation is a mathematical technique, introduced by Paul Peter Ewald in 1921, that computes long-range Coulomb interactions in periodic charged systems by splitting the sum into real-space and reciprocal-space parts.

Ewald Warning

Ewald Warning was a mathematician who published as E. Warning; his 1935 note, following Chevalley's work, became half of the Chevalley–Warning theorem in number theory.

Ewald Wicke

Ewald Wicke (1914–2000) was a German physical chemist who held the Chair of Physical Chemistry at the University of Münster from 1959 to 1982 and bridged physical chemistry with chemical engineering.
