Douglas Wilson Johnson
Douglas Wilson Johnson (1878–1944) was an American geomorphologist at Columbia University, known for Shore Processes and Shoreline Development (1919) and Stream Sculpture on the Atlantic Slope (1931).
Douglas Woodall
Douglas Robert Woodall, born 1943, is a British mathematician who worked at the University of Nottingham from 1969 to 2007, known for graph colorings and electoral theory.
Dov Levine
Dov Levine is a condensed matter theorist who co-founded the theory of quasicrystals with Paul Steinhardt in 1984 and is a professor of physics at the Technion in Israel.
Dovitinib
Dovitinib (TKI258, CHIR-258) is an oral multi-target tyrosine kinase inhibitor against FGFR, VEGFR, PDGFR, FLT3, KIT, and RET, trialed in RCC, HCC, and breast cancer; not FDA approved.
Down quark
The down quark (symbol d), also called the D quark, is a first-generation quark with electric charge −1/3 e that combines with up quarks to form protons (uud) and neutrons (ddu).
Downburst
A downburst, also known as a Plough Wind, is a strong downdraft from a thunderstorm that strikes the ground and spreads outward as damaging straight-line winds, named by Ted Fujita in 1976.
Downscaling (climate modeling)
Downscaling is a family of techniques that translate coarse global climate model output, on grids of 100 to 300 km, into regional and local climate information for impact and risk assessment.
Downslope windstorm
A downslope windstorm is a period of strong, gusty winds descending the lee side of a mountain range. The warm North American variety is the Chinook wind.
Downward continuation
Downward continuation is a geophysical processing technique that projects potential field data, such as gravity or magnetic anomalies, to a level closer to its sources, enhancing shallow features.
Downwash
Downwash is the downward-deflected flow of air behind a lifting surface such as a wing, produced by wingtip vortices; it reduces the effective angle of attack and adds induced drag.
DOx (psychedelics)
The DOx compounds are a family of psychedelic amphetamines, including DOM, DOC, DOB, and DOI, that act mainly as 5-HT2A receptor agonists and have been sold as LSD.
Doxastic logic
Doxastic logic is a branch of modal logic that formalizes reasoning about belief, initiated by Jaakko Hintikka in 1962 and distinguished from knowledge by beliefs that can be false.
Dozen
A dozen, known in German as Dutzend and Dutch as Dozijn, is a grouping of twelve items used in commerce since medieval Europe; a baker's dozen is thirteen.
DP Leo
DP Leo (DP Leonis), an eclipsing polar cataclysmic variable in Leo with an 89.8-minute binary orbit, hosts the circumbinary giant planet DP Leo b, about 6.3 Jupiter masses on a 28-year, 8.19 AU eccentric orbit, found by eclipse timing variations.
DP-GEN
DP-GEN (Deep Potential GENerator) is an open-source concurrent-learning workflow introduced by Zhang and colleagues in 2019 that automates iterative training of Deep Potential machine-learning interatomic potentials, labeling only uncertain configurations.
DP-water
DP-water is a machine-learning molecular dynamics model of water built with the Deep Potential neural-network method, trained on density functional theory data, best known from a 2021 model.
DPCPX
DPCPX, also known as CPX or PD 116948, is a xanthine derivative and selective antagonist of the adenosine A1 receptor whose tritiated form is the standard radioligand for that receptor.
DPG Spring Meetings
The DPG Spring Meetings (Frühjahrstagungen) are the annual spring conferences of the German Physical Society, held each year in several German cities with around 10,000 participants.
DPLL algorithm
The DPLL algorithm (Davis–Putnam–Logemann–Loveland) is a complete backtracking search procedure for deciding whether a Boolean CNF formula is satisfiable, published in 1960–1962 by Davis, Putnam, Logemann, and Loveland.
DPPH assay
The DPPH assay, or DPPH method, is a colorimetric test that measures antioxidant activity by tracking the loss of the violet DPPH radical at 517 nm.
DQ Herculis
DQ Herculis, also DQ Her, is an eclipsing cataclysmic variable in Hercules, famous as Nova Herculis 1934 and as the prototype of the intermediate polars, magnetic cataclysmic variables with a spinning white dwarf.
DQ Tau
DQ Tau is a young spectroscopic binary in the constellation Taurus: two nearly equal-mass T Tauri stars on an eccentric 15.8-day orbit, known as the archetype for pulsed accretion.
DR 21
DR 21 is a massive star-forming region in the Cygnus X complex of the constellation Cygnus, home to a bright HII region and one of the Galaxy's most powerful molecular outflows.
DR Tau
DR Tau is a highly active classical T Tauri star in the Taurus-Auriga star-forming region, still accreting material from its disk and among the most variable of its class.
Draco (constellation)
Draco, the Dragon, is a large circumpolar constellation of the northern sky listed by Ptolemy, whose star Thuban was the pole star when the Egyptian pyramids were built.
Draco Dwarf
The Draco Dwarf, also called Draco dSph, is a faint satellite galaxy of the Milky Way in the constellation Draco about 260,000 light-years away, dominated by dark matter.
