Deep dermatophytosis

Deep dermatophytosis, or disseminated granulomatous dermatophytosis, is a rare, life-threatening invasion of dermis and subcutaneous tissue by dermatophytes, mainly Trichophyton rubrum, in CARD9-deficient or immunocompromised patients, with lymph node dissemination and terbinafine or itraconazole treatment.

Deep Deterministic Policy Gradient

Deep Deterministic Policy Gradient (DDPG) is a model-free, off-policy actor-critic reinforcement learning algorithm for continuous action spaces, introduced in 2015 by Timothy Lillicrap and colleagues at DeepMind.

Deep Dish

Deep Dish is an American electronic music duo of Iranian-born DJs and producers Ali "Dubfire" Shirazinia and Sharam Tayebi, formed in Washington, D.C. in 1992.

Deep diving

Deep diving (freediving): breath-hold descent to maximum depth in open water, via CWT, CNF, FIM, or variable-weight sled disciplines under AIDA and CMAS rules; median competition personal best 46.5 m, elite divers exceed 110 m.

Deep drawing

Deep drawing is a sheet metal forming process in which a punch presses a flat blank into a die to form a hollow body such as a cup or sink.

Deep ecology

Deep ecology, coined by Arne Næss in 1973, is a radical environmental ethics movement holding that all living things have intrinsic value (biospheric egalitarianism), opposed to shallow ecology focused on pollution and developed-country affluence; criticized by Bookchin, Guha, and ecofeminists.

Deep End (music)

"Deep End" is a 2020 tech-house single by American DJ and producer John Summit, released on Defected Records on June 26, 2020, and the longest-running Beatport number one of 2020.

Deep energy retrofit

A deep energy retrofit (DER) is a whole-building renovation that cuts a building's energy use far more than a conventional retrofit, often by more than 50 percent.

Deep ensembles

A deep ensemble is a set of independently trained neural networks whose averaged predictions provide uncertainty estimates, introduced by Lakshminarayanan and colleagues at DeepMind in 2016.

Deep eutectic solvent extraction

Deep eutectic solvent (DES) extraction is a separation method that uses deep eutectic solvents, typically hydrogen bond donor and acceptor mixtures, to isolate compounds from plant material, oils, and aqueous samples.

Deep eutectic solvents

Deep eutectic solvents are mixtures of hydrogen bond acceptors and donors whose freezing point falls far below those of the components, described in 2003 for choline chloride and urea.

Deep eutectic solvents for PET depolymerization

Deep eutectic solvents for PET depolymerization are mixtures of a hydrogen-bond donor and acceptor, typically choline chloride with urea or an alcohol, that act as both solvent and catalyst to break PET into monomers.

Deep excavation support systems

Deep excavation support systems combine retaining walls, such as sheet piles, secant piles, and diaphragm walls, with bracing, tiebacks, or floor slabs to stabilize deep cuts and protect adjacent structures.

Deep Forest

Deep Forest: French electronic/world music project founded 1992 by Eric Mouquet and Michel Sanchez; hit "Sweet Lullaby," Grammy-winning Boheme (1996), 10M+ albums, Mouquet solo since 2005.

Deep fryer

A deep fryer is a kitchen appliance that cooks food submerged in hot oil, typically at 150 to 200 °C, from countertop units to industrial lines.

Deep frying

Deep frying: cooking by full immersion in hot oil above water's boiling point (140–180 °C), forming a crispy crust; most oil uptake occurs during cooling; industrialized since the late 1890s for potato chips.

Deep generative model

A deep generative model is a neural network method that learns the probability distribution of training data and draws new samples resembling it, including GANs, VAEs, and diffusion models.

Deep geological repository

A deep geological repository is an underground facility, typically several hundred meters deep, for permanent disposal of spent nuclear fuel and high-level waste using engineered and natural barriers, with Finland's Onkalo the first operating one.

Deep Glider

The Deepglider is an autonomous underwater glider from the University of Washington that profiles the ocean from the surface to 6,000 meters using buoyancy rather than a propeller.

Deep gluteal syndrome

Deep gluteal syndrome (DGS), formerly piriformis syndrome, is non-discogenic sciatic nerve entrapment in the deep gluteal space causing buttock pain and sciatica; diagnosed by provocation tests and pelvic MRI, treated conservatively first.

Deep hashing

Deep hashing is a machine learning method that trains a deep neural network to map inputs, typically images, to compact binary codes for fast similarity search.

Deep Heat Mining Basel

Deep Heat Mining Basel was a Swiss enhanced geothermal project beneath Basel, abandoned in 2009 after induced earthquakes, including a magnitude 3.4 event in December 2006.

Deep hole drilling

Deep hole drilling is a machining process for holes whose depth greatly exceeds their diameter, using self-piloting tools and high-pressure coolant; its variants include gun drilling, BTA, and ejector drilling.

Deep house

Deep house is a subgenre of house music, also called deep house, that emerged in Chicago and New York in the mid-1980s with Larry Heard; it runs about 110–125 BPM with jazz-influenced chords, warm sub-bass, and restrained, atmospheric arrangements.
