Filo (φύλλο)
Filo (φύλλο, phyllo, fillo), Greek for "leaf", is paper-thin unleavened dough layered with brushed butter or oil for baklava, spanakopita, and börek; unlike puff pastry, its fat is applied between sheets, not laminated into the dough.
Filo del Sol
Filo del Sol is a copper-gold-silver deposit in the high Andes on the Argentina-Chile border, described by BHP as the largest greenfield copper discovery in 30 years.
Filo Musiaco
Filo Musiaco (Filomusiacum), an unlocated Roman road station on the Tabula Peutingeriana between Vesontine (Besançon) and Abiolica (Pontarlier), 15 leugae from Besançon; proposed sites include Mouthier, Fallerans, and Nods/La Malepierre.
Filocolo
Filocolo is a prose romance in five books by Giovanni Boccaccio, written in Naples between 1336 and 1338, and the first prose romance of Italian literature.
Filofei's letters on Moscow as the Third Rome
Filofei's letters on Moscow as the Third Rome (Послания старца Филофея) are epistles by the Pskov monk Filofei, written around 1523–1524, declaring Moscow the successor of fallen Rome and Constantinople.
Filoli
Filoli is a 654-acre historic estate in Woodside, California, built 1915-1917 for William Bowers Bourn II, with a Georgian Revival mansion and 16 acres of English Renaissance gardens; a National Trust property opened to the public in the mid-1970s and famed as Dynasty's Carrington mansion.
Filosofem
Filosofem is Burzum's fourth album by Varg Vikernes, recorded in 17 hours in March 1993 and released January 1996; a deliberately lo-fi, anti-black-metal landmark of atmospheric black metal.
Filostrato
Il Filostrato, meaning "prostrated by love," is a narrative poem in nine parts by Giovanni Boccaccio, written around 1335 in ottava rima, best known as the principal source of Chaucer's Troilus and Criseyde.
Filoviridae
Filoviridae, the filovirus family, is a group of filamentous negative-sense RNA viruses in the order Mononegavirales with 13.1–20.9 kb genomes, 9 genera infecting fish, mammals, and reptiles, including the lethal human pathogens Ebola virus and Marburg virus.
Filter (band)
Filter is an American industrial-influenced hard rock band formed in Cleveland, Ohio in 1993 by Richard Patrick after leaving Nine Inch Nails; platinum albums Short Bus (1995) and Title of Record (1999), hits "Hey Man, Nice Shot" and "Take a Picture," eighth album The Algorithm (2023).
Filter (mathematics)
In mathematics, a filter is a non-empty family of subsets closed under finite intersections and upward inclusion and excluding the empty set, introduced by Henri Cartan in 1937.
Filter (signal processing)
In signal processing, a filter is a system that selectively modifies a signal's frequency content, passing some frequencies while attenuating others, and exists in analog and digital form.
Filter bank multicarrier
Filter bank multicarrier (FBMC) is a multicarrier modulation scheme transmitting parallel streams through modulated filters, studied as a 5G alternative to cyclic-prefix OFDM with lower out-of-band emissions but higher complexity.
Filter bubble
A filter bubble, or informational bubble, is a state in which algorithmic personalization of online content isolates users from disagreeing material, coined by Eli Pariser in 2011.
Filter design
Filter design is the process of turning a frequency-response specification into a working filter: a transfer function and coefficients for a digital filter, or a circuit topology for an analog one.
Filter feeder
A filter feeder is an animal that strains food from water flowing through its body, a strategy seen from sponges and oysters to baleen whales, which evolved it from toothed ancestors.
Filter model
A filter model is a mathematical model of the untyped lambda-calculus whose elements are filters of intersection types, introduced by Barendregt, Coppo, and Dezani-Ciancaglini in 1983.
Filter paper
Filter paper is a semi-permeable paper barrier placed perpendicular to a liquid or airflow, used to separate fine solid particles from liquids or gases in laboratory filtration.
Filter stability and approximation in nonlinear filtering
Filter stability is the property of a nonlinear filter whereby its estimates become insensitive to the initial condition as observations accumulate, and it underpins accurate particle filter approximation.
Filtered back projection
Filtered back projection (FBP) is a tomographic reconstruction algorithm that filters each projection with a ramp and back-projects it into a cross-sectional image, long the standard method in CT.
Filtered containment venting
Filtered containment venting is a nuclear reactor safety system that relieves containment overpressure through filters during severe accidents, retaining most radioactive aerosols and much iodine.
Filtered multitone
Filtered multitone (FMT) is a multicarrier modulation technique whose filter-shaped subchannels have essentially no spectral overlap, proposed for VDSL transmission by IBM researchers in 1999.
Filtered OFDM
Filtered OFDM (f-OFDM) is a multicarrier transmission scheme that splits an OFDM signal into subbands, each filtered, so different services can use different subcarrier spacings within one carrier.
Filtering Surgery
Filtering surgery (glaucoma filtration surgery, trabeculectomy) creates a fistula draining aqueous humor to a subconjunctival bleb to lower IOP; developed from De Wecker's 1882 fistula to Cairns' 1968 guarded trabeculectomy, now alongside tube shunts and MIGS.
Filth (film)
Filth (2013) is Jon S. Baird's black comedy adaptation of Irvine Welsh's 1998 novel, starring James McAvoy as corrupt Edinburgh detective Bruce Robertson. Released 27 September 2013, it earned £3.9 million in the UK and won McAvoy BIFA and BAFTA Scotland acting awards.
Filthy Rich (2020 TV series)
Filthy Rich (2020) is a Fox Southern Gothic family drama created by Tate Taylor, adapted from the 2016 New Zealand series by Rachel Lang and Gavin Strawhan. Kim Cattrall stars as Margaret Monreaux; 10 episodes, canceled after one season.
Filthy Rich & Catflap
Filthy Rich & Catflap (also styled Filthy, Rich and Catflap) is a 1987 BBC Two sitcom by Ben Elton starring Rik Mayall, Adrian Edmondson, and Nigel Planer; six episodes bridging The Young Ones and Bottom, cancelled after one series despite an announced return.
Filthy Thirteen
Filthy Thirteen: nickname of the 1st Demolition Section, RHQ Company, 506th PIR, 101st Airborne, led by Jake McNiece; mohawks and war paint on D-Day, Douve bridges, Bastogne pathfinder jump, inspiration for The Dirty Dozen.
Filtration
Filtration is a separation process removing suspended solids from a liquid or gas by forcing the fluid through a porous medium such as filter paper or a sand bed.
Filtration (probability theory)
A filtration in probability theory is an increasing family of σ-algebras on a probability space, indexed by time, modeling the accumulation of information; it underlies martingales and stopping times.
