Transportation management system
A transportation management system (TMS) is specialized software for planning, executing, and optimizing the shipment of goods, letting users compare carrier rates, book shipments, and track delivery.
Transportation of Patients
Transportation of patients (MeSH D014187): conveying ill or injured people between locations, from prehospital ambulance and interfacility transport to intrahospital moves; distinct from administrative patient transfer, with roots in military and 19th-century urban ambulance services.
Transportation Research Board
Transportation Research Board (TRB), founded 1920 as the National Advisory Board on Highway Research, is a division of the National Academies managing cooperative research programs (NCHRP, TCRP, ACRP), the TRID database, and the January Annual Meeting in Washington, D.C.
Transportation Research Center
The Transportation Research Center is an independent, nonprofit vehicle proving ground in East Liberty, Ohio, the largest in North America, opened in 1974 and affiliated with The Ohio State University.
Transportation Safety Board of Canada
The Transportation Safety Board of Canada (TSB) is an independent federal agency that investigates aviation, marine, rail, and pipeline accidents to find causes, without assigning fault or liability.
Transportation Security Administration
The Transportation Security Administration (TSA), created by the Aviation and Transportation Security Act of November 2001, is the U.S. DHS agency screening air travelers; roughly 60,000 employees screen passengers at about 440 airports, with PreCheck, REAL ID, and covert-test oversight issues.
Transportation theory (mathematics)
Transportation theory, also called optimal transport, is the mathematical study of moving one distribution of mass onto another at minimum cost, originating with Monge in 1781.
Transporter (franchise)
The Transporter is a French action franchise centered on professional driver Frank Martin, which began with the 2002 film written and produced by Luc Besson and starring Jason Statham.
Transporter 2
Transporter 2 (French: Le Transporteur 2) is a 2005 action thriller directed by Louis Leterrier and starring Jason Statham as Frank Martin, a driver in Miami protecting a kidnapped boy, the sequel to The Transporter.
Transporter 3
Transporter 3 (Le Transporteur III) is a 2008 action film directed by Olivier Megaton, the third in the Transporter franchise, starring Jason Statham as courier Frank Martin.
Transporter bridge
A transporter bridge, also known as a ferry bridge or aerial transfer bridge, is a bridge with a fixed high frame and a suspended gondola that ferries people and vehicles across a river.
Transporter erector launcher
A transporter erector launcher (TEL) is a single vehicle that transports, erects, and launches missiles without fixed infrastructure, carrying everything from tactical missiles to ICBMs like the Scud-B.
Transporter-1

Transporter: The Series
Transporter: The Series is a France-Canada-Germany action TV series (2012, 2014) starring Chris Vance as courier Frank Martin, adapted from Luc Besson's Transporter films, 24 episodes over two seasons.
Transposable element
Transposable element (TE, jumping gene): mobile DNA sequence moving within genomes via RNA (Class I retrotransposons) or DNA (Class II transposons) intermediates; ~45% of the human genome; discovered by McClintock in maize, Nobel 1983.
Transposase for transposon Tn5
Tn5 transposase (Tnp), the 476-aa DDE enzyme encoded by IS50R in bacterial transposon Tn5, catalyzes cut-and-paste transposition at 19 bp ends; hyperactive derivatives power ATAC-seq, CUT&Tag, and Nextera tagmentation.
Transposase protein
Transposase: enzyme encoded by autonomous DNA transposons that cuts and rejoins DNA to move transposons without RNA intermediates; four catalytic families (DDE/RNase H-like, HUH, serine, tyrosine); the most abundant genes in sequenced genomes.
Transpose
The transpose, also called the matrix transpose or matrix transposition, is the matrix Aᵀ formed by exchanging rows and columns of A, an m×n matrix becoming n×m.
Transposition (music)
Musical transposition is the notation or performance of music at a pitch different from the original, by raising or lowering every note by the same interval.
Transposition cipher
A transposition cipher, also known as a permutation cipher, encrypts by rearranging letters rather than replacing them, a classical method whose variants include columnar and rail fence.
Transposition of the great vessels
Transposition of the great vessels, or transposition of the great arteries, is a congenital heart defect in which the aorta and pulmonary artery arise from reversed ventricles, causing cyanosis at birth.
Transposon mutagenesis
Transposon mutagenesis is a genetic technique that uses mobile DNA elements called transposons to insert mutations into a genome, disrupting genes and linking genotype to phenotype.
Transposon Tn7 transposition protein TnsD, middle domain
TnsD middle domain: the 329–345 linker between the N-terminal (1–328) and C-terminal (346–462) domains of TnsD, the Tn7 transposon target selector that binds glmS attTn7 and recruits TnsC.
Transpression
Transpression is a style of deformation in which strike-slip shearing combines with shortening across the shear zone, a term introduced by W. B. Harland in 1971.
Transracial (identity)
Transracial (identity) covers transracial adoptees raised across race lines and the contested self-identification sense highlighted by Rachel Dolezal and the 2017 Tuvel Hypatia controversy.
Transrapid
Transrapid was a German high-speed magnetic levitation train system developed from the late 1960s, capable of 500 km/h, whose only commercial line runs in Shanghai.
Transrectal ultrasound-guided biopsy
Transrectal ultrasound-guided (TRUS) biopsy is a diagnostic procedure that uses spring-loaded needles to sample prostate cores through the rectum, typically taking 10 to 12 cores.
TransSakhalin Gas Pipeline System
TransSakhalin Gas Pipeline System is the twin oil and gas pipeline network of the Sakhalin-2 project on Sakhalin Island, running about 800 km from northern offshore platforms to Prigorodnoye, which has Russia's first LNG plant.
