Lift coefficient

The lift coefficient, or coefficient of lift, is a dimensionless number that combines the effects of wing shape, angle of attack, and flow conditions on lift in the lift equation.

Lift-off process

The lift-off process is an additive microfabrication technique that patterns evaporated metal films by dissolving a sacrificial resist stencil, used for contacts and interconnects in semiconductor and MEMS manufacturing.

Lift-to-drag ratio

The lift-to-drag ratio, abbreviated L/D and also called lift over drag, is the ratio of aerodynamic lift to drag and the standard measure of aircraft aerodynamic efficiency.

Liftback

A liftback is a car body style with a single top-hinged rear door incorporating the rear window, combining fastback-like proportions with hatchback cargo access; Toyota coined the term in 1973.

Lifted condensation level

The lifted condensation level (LCL) is the altitude at which a rising unsaturated air parcel cools to saturation and condensation begins, used to estimate convective cloud bases.

Lifted index

The lifted index (LI) is a meteorological stability index measuring lower-troposphere instability by lifting a surface air parcel to 500 mb; negative values indicate instability and stronger updrafts.

Lifting body

A lifting body is a wingless aircraft or spacecraft that generates lift from its fuselage shape, allowing a returning space vehicle to maneuver and land on a runway.

Lifting scheme

The lifting scheme is a method for constructing wavelets and computing the discrete wavelet transform through split, predict, and update steps, introduced by Wim Sweldens in 1995.

LIFTRAF-RCT trial

LIFTRAF-RCT (NCT05263661) is a phase III randomized trial at Hospital General Universitario Reina Sofía de Murcia, Spain, comparing LIFT with rectal advancement flap in 72 patients with complex anal fistula, with 12-month recurrence as the primary endpoint.

LIG Nex1

LIG Nex1 (LIG넥스원) is a South Korean defense company, founded in 1976 as Goldstar Precision, making missiles, radars, avionics, and unmanned systems, and exporting the Cheongung-II air defense system.

LIG1

LIG1 (DNA ligase 1, hLig1, IMD96), gene ID 3978 at 19q13.33, encodes the main human nuclear replicative DNA ligase that seals Okazaki fragments via PCNA recruitment; hypomorphic mutations cause LIG1 Syndrome immunodeficiency.

LIG3

LIG3 (DNA ligase 3, MTDPS20) is a human chromosome 17 gene encoding ATP-dependent DNA ligases; via alternative start codons it makes the sole mitochondrial DNA ligase plus nuclear ligase IIIalpha, essential for mtDNA maintenance.

LIG4

LIG4 (DNA ligase 4, gene at 13q33.3) encodes the ATP-dependent ligase that seals DNA double-strand breaks in NHEJ and V(D)J recombination; biallelic hypomorphic mutations cause LIG4 syndrome with microcephaly, radiosensitivity and immunodeficiency.

LIG4 syndrome

LIG4 syndrome, also called DNA ligase IV syndrome (OMIM 606593, ORPHA 99812), is a rare autosomal recessive NHEJ repair disorder causing microcephaly, bird-like facies, radiosensitivity, combined immunodeficiency, pancytopenia, and lymphoid malignancy risk.
