Dynegy Moss Landing power plant

Natural gas-fired generating and battery storage complex at Moss Landing, California, combining a 1,060 MW combined-cycle plant with one of the world's largest battery storage facilities.

Dynein

Dynein: AAA+ microtubule motor proteins moving toward the minus end; cytoplasmic dynein-1 drives cargo transport and spindle assembly, dynein-2 powers intraflagellar transport, axonemal dyneins beat cilia; regulated by dynactin and Lis1.

Dynein heavy chain

The dynein heavy chain is the roughly 500 kDa catalytic subunit of dynein, the motor protein that converts ATP energy into minus-end-directed movement along microtubules.

Dynein light chain Tctex-1-like

Dynein light chain Tctex-1-like (IPR005334) is a protein family of ~113-residue dynein light chains including DYNLT1/Tctex-1, a homodimeric 14-kDa cargo adaptor of cytoplasmic dynein with dynein-independent roles in actin remodeling and mitosis.

Dynein regulator LIS1

LIS1 (PAFAH1B1, Lissencephaly-1) is a 45 kDa WD40-repeat dynein regulator on chromosome 17p13.3; with NudE/NudEL it drives dynein force production under load, and its mutation causes lissencephaly.

Dynkin diagram

A Dynkin diagram is a graph encoding a root system, with one vertex per simple root, introduced by Evgeny Dynkin in 1947 to classify semisimple Lie algebras.

DYNLL1

DYNLL1 (LC8, PIN, DLC1) is a conserved 89-aa homodimeric dynein light chain and hub protein on human 12q24.31 that binds TQT-type linear motifs, promotes partner dimerization, and is essential for dynein, cilia, B cell development, and DNA repair.

Dyno Nobel

Dynoro

Dynoro is the stage name of Edvinas Pechovskis, a Lithuanian DJ and producer born in Vilnius in 1999, best known for the 2018 single "In My Mind".

Dynorphin

Dynorphin is an endogenous opioid neuropeptide, discovered in porcine pituitary tissue in 1975, that preferentially binds the kappa opioid receptor and regulates pain, mood, stress, and addiction.

Dyphylline

Dyphylline (diprophylline, dihydroxypropyltheophylline; brands Lufyllin, Dilor, Neothylline) is a theophylline-derivative xanthine bronchodilator for asthma and COPD, excreted unchanged by the kidneys, FDA-approved 1951 and later discontinued in the US.

Dyrehavsbakken

Dyrehavsbakken (Bakken), founded 1583 in Jægersborg Dyrehave near Klampenborg, is the world's oldest operating amusement park, with free entrance, 36 rides, and about 2.4 million estimated annual visits, second in Denmark after Tivoli.

DYRK1A

DYRK1A (dual specificity tyrosine phosphorylation regulated kinase 1A) is a chromosome 21 kinase, the minibrain homolog, overexpressed 1.5-fold in Down syndrome and targeted by inhibitors such as harmine.

DYRK1A-related intellectual disability syndrome

DYRK1A-related intellectual disability syndrome (DYRK1A syndrome, MRD7): rare autosomal dominant neurodevelopmental disorder from DYRK1A loss-of-function at 21q22.13, causing microcephaly, speech impairment, ASD, and dysmorphic features.

Dyrol Burleson

Dyrol Burleson (born 1940, Saginaw, Oregon), American miler, University of Oregon star under Bill Bowerman. Two-time Olympic 1500 m finalist (6th 1960, 5th 1964), 1959 Pan Am gold, three NCAA titles, first sub-4 mile at Hayward Field.

Dyrr(h)achium/Epidamnos

Epidamnos/Dyrrhachium (Durrës, Albania), Greek colony founded 627 BC by Corcyra and Corinth; Roman Adriatic port, Via Egnatia terminus, Caesar-Pompey battle site, amphitheatre.

Dyrus

Dyrus is the game handle of Marcus Hill, an American former professional League of Legends player, the top laner for Team SoloMid from 2012 to 2015.

DYS-NOC trial

DYS-NOC (NCT02801838), also called ADOREPS_2, was a French single-center interventional diagnostic trial validating the IC-RDOS observational dyspnea scale in non-communicating ventilated ICU patients against EMG and EEG markers, with ventilator optimization and up to 10 mg morphine titration.

DYS-PAV trial

DYS-PAV (NCT02801994) was a French single-center physiological trial at Pitié-Salpêtrière, Paris, testing proportional assist ventilation (PAV+) versus personalized pressure support in 34 dyspneic ventilated ICU patients; PAV+ relieved dyspnea similarly but reduced asynchrony more.
