Anisotropic conductive film

Anisotropic conductive film (ACF) is a thermosetting adhesive filled with conductive particles that bonds chips to glass panels, conducting vertically and insulating adjacent terminals, standard in flat panel displays.

Anisotropic diffusion (image processing)

Anisotropic diffusion is a PDE-based image-smoothing technique that reduces noise while keeping region boundaries sharp, introduced by Pietro Perona and Jitendra Malik in 1990 and used in denoising and segmentation.

Anisotropic elasticity

Anisotropic elasticity is the branch of continuum mechanics describing solids whose stress-strain response depends on direction, requiring up to 21 independent elastic constants rather than 2.

Anisotropic filtering

Anisotropic filtering is a texture filtering technique in computer graphics that reduces blurring and aliasing on surfaces viewed at grazing angles, such as receding floors and roads.

Anisotropic magnetoresistance

Anisotropic magnetoresistance (AMR) is a magnetotransport effect in ferromagnetic materials in which resistance depends on the angle between current and magnetization, first observed by William Thomson in the 1850s.

Anisotropic star

An anisotropic star is a general-relativistic model of a compact star whose radial and tangential pressures differ, relaxing the Buchdahl bound and allowing greater compactness.

Anisotropic wet etching

Anisotropic wet etching is a microfabrication process that dissolves single-crystal silicon at rates depending on crystallographic orientation, typically with KOH or TMAH, and underpins MEMS fabrication.

Anisotropine

Anisotropine methylbromide (octatropine methylbromide), a quaternary ammonium antimuscarinic tropane derivative once sold as Valpin 50 for peptic ulcer; discontinued, replaced by more effective agents.

Anisotropy

Anisotropy is the dependence of a physical property of a material on the direction of measurement, the opposite of isotropy; crystalline solids are generally anisotropic.

Anisotropy of magnetic susceptibility

Anisotropy of magnetic susceptibility (AMS) is the dependence of a rock's magnetic susceptibility on field direction, defined by three principal susceptibilities forming an ellipsoid that records mineral fabric.

Anisotropy of ultra-high-energy cosmic rays

The anisotropy of ultra-high-energy cosmic rays is the non-uniform arrival directions of cosmic rays above 8 EeV, established by the Pierre Auger Observatory and Telescope Array.

Anissa Jones

Anissa Jones (Mary Anissa Jones, 1958-1976), American child actress of Lebanese descent who played Buffy Davis on CBS's Family Affair (1966-1971, 138 episodes); died at 18 in Oceanside, California, of combined drug intoxication. Not the Georgia legislator of the same name.

Anistreplase

Anistreplase (APSAC, Eminase) is an acylated streptokinase-lys-plasminogen thrombolytic complex, given as a 30-unit IV bolus over 2-5 minutes, half-life about 90 minutes, FDA approved 1989 for acute myocardial infarction.

Anisya Kirdyapkina

Anisya Kirdyapkina (Анися Кирдяпкина), born 1989 in Saransk, Russian 20 km race walker; 2010 European champion, 2014 World Race Walking Cup winner, 2009 World bronze; stripped of 2011–2013 results for biological passport irregularities and DQ from London 2012.

Anisyl alcohol

Anisyl alcohol, also known as anise alcohol, is 4-methoxybenzyl alcohol, a primary aromatic alcohol with a sweet, lilac-and-vanilla odor, used mainly as a flavoring agent and fragrance ingredient.

ANITA (balloon experiment)

ANITA (Antarctic Impulsive Transient Antenna) was a NASA balloon-borne experiment that flew four flights over Antarctica between 2006 and 2016, searching for ultra-high-energy neutrinos via radio pulses in the ice.

Anita Anand

Anita Anand names two figures: Anita Indira Anand (born 1967), Canada's Minister of Foreign Affairs and former University of Toronto law professor, and Anita Anand (born 1972), a British BBC broadcaster and author.
