The Antikythera mechanism (Μηχανισμός των Αντικυθήρων) is an ancient Greek geared bronze device, recovered from a shipwreck off Antikythera, that predicted eclipses and tracked lunar cycles.
Antilag system
The antilag system, also known as a misfiring system, keeps a turbocharged engine's turbo spinning during throttle lifts, used almost exclusively in motorsport like rallying.
Antilia (building)
Antilia, also known as Antilia Mumbai, is a 27-floor, 173-meter private residential skyscraper on Altamount Road in Mumbai owned by Mukesh Ambani, completed in 2010 and listed by Guinness as the world's most expensive private residence.
Antilia Faculae
Antilia Faculae is a 260-km-wide bright spot (facula) on Titan near 11°S, 187°W, IAU-approved in 2006 and named for the mythical island of Antilia.
Antillanca Volcanic Complex
The Antillanca Volcanic Complex is a volcanic field in the southern Andes of Chile, southeast of Lago Puyehue, whose highest peak is the Casablanca stratovolcano.
Antillanité
Antillanité, a literary and political concept formulated by Martinican writer Édouard Glissant in the late 1950s, roots Antillean identity in the islands' own cultural and ethnic diversity rather than a single ancestral origin.
Antilles
The Antilles are the Caribbean island chains forming the West Indies with the Bahamas: the Greater Antilles (Cuba, Jamaica, Hispaniola, Puerto Rico), continental fragments, and the volcanic Lesser Antilles arc.
Antillia
Antillia (Antilia), the Island of the Seven Cities, was a phantom island of the Atlantic drawn on portolan charts from 1424 to about 1587, tied to the seven bishops legend, sought by Columbus, and source of the name Antilles.
Antilocapridae
Antilocapridae, the pronghorn family, is a North American artiodactyl family with one living species, Antilocapra americana, a Miocene-to-Pleistocene fossil record, annually shed keratinous horn sheaths, and giraffes as closest living relatives.
Antim: The Final Truth
Antim: The Final Truth (अंतिम: एक आखिरी सच) is a 2021 Hindi action crime film directed by Mahesh Manjrekar, a remake of Mulshi Pattern, starring Salman Khan as a Sikh cop and Aayush Sharma as gangster Rahuliya; released 26 November 2021, a box office flop.
Antimalarial medication
Antimalarial medication: drugs to treat or prevent malaria. Key classes are artemisinin combination therapies (WHO first-line for P. falciparum), quinolines, antifolates, and 8-aminoquinolines; resistance to chloroquine and artemisinin partial resistance shape current guidance.
Antimatter
Antimatter, also known as contraterrene matter, is matter composed of antiparticles, such as the positron, that annihilate with ordinary matter and release energy; no significant amounts exist naturally in the universe.
Antimatter propulsion spacecraft
An antimatter propulsion spacecraft, or antimatter rocket, is a proposed spacecraft powered by antimatter annihilation, the highest energy density reaction known; none has been built, only design studies.
Antimatter tests of Lorentz violation
Experiments that compare antiparticles and anti-atoms with their matter counterparts, or monitor them over time, to search for tiny departures from Lorentz symmetry and thereby constrain CPT symmetry.
Antimatter weapon
An antimatter weapon, also called an antimatter bomb or antimatter explosive, is a hypothetical explosive using antimatter annihilation, studied since the 1940s but never built because production is far too slow.
Antimicrobial
Antimicrobial: umbrella term for agents killing or inhibiting microbes, covering antibiotics, antifungals, antivirals, and antiparasitics; distinguished from the narrower term antibiotic, with global resistance tracked by WHO GLASS.
Antimicrobial agents and chemotherapy
Antimicrobial Agents and Chemotherapy (AAC) is a monthly ASM journal, ISSN 0066-4804, founded January 1972 by Gladys Hobby from the 1961–1970 ICAAC proceedings volumes, covering antibacterial, antiviral, antifungal, and antiparasitic agents; online only since 2014.
Antimicrobial peptides
Antimicrobial peptides (AMPs), also called host defense peptides, are small innate-immunity proteins, mostly cationic and amphipathic, that kill bacteria, viruses, and fungi by membrane disruption and immunomodulation, with over 3,000 reported and peptide antibiotics such as daptomycin in clinical use.
Antimicrobial photodynamic therapy
Antimicrobial photodynamic therapy, also called photodynamic antimicrobial chemotherapy or aPDT, uses a light-activated dye to generate reactive oxygen species that kill antibiotic-resistant microbes, mainly in topical skin applications.
Antimicrobial properties of copper
Antimicrobial properties of copper: contact killing of bacteria, fungi, and viruses on copper surfaces via ROS, membrane damage, and Cu+/Cu2+ ions; EPA-registered since 2008; mixed clinical evidence for reducing hospital infections.
Antimicrobial resistance
Antimicrobial resistance (AMR), or drug resistance in bacteria, fungi, viruses, and parasites, accelerated by antimicrobial misuse; caused 1.27 million attributable deaths in 2019, with one in six infections resistant in 2023.
Antimicrobial Stewardship
Antimicrobial stewardship (AMS), also called antibiotic stewardship, coordinates strategies to optimize antimicrobial use, reduce resistance, and cut costs; term coined 1996, CDC Core Elements since 2014, over 80% of use is outpatient.
Antimicrobial susceptibility testing
Antimicrobial susceptibility testing (AST) is a laboratory method that measures how antimicrobial drugs inhibit a bacterial isolate, classifying it as susceptible or resistant to guide therapy.
Antimilitärischer Apparat
Antimilitärischer Apparat (AM-Apparat), also M-Apparat or Kippenberger-Apparat: the Communist Party of Germany's intelligence service, about 1921 to 1937, covering espionage, counterintelligence, police and army subversion, and Soviet-linked covert work.
Antimonene
Antimonene is a two-dimensional material consisting of a single layer of antimony atoms, like graphene. Predicted in 2015 and isolated in 2016, it is known for strong spin–orbit coupling and air stability.
Antimony
Antimony, known in Latin as stibium (symbol Sb), is a hard, brittle metalloid element with atomic number 51, used mainly in flame retardants, lead-acid batteries, and ammunition.
