Distinct from the 1993 film Blood In Blood Out.
Bound entanglement and the distillability problem
Bound entanglement is mixed-state quantum entanglement that cannot be distilled into singlets by LOCC, established by the Horodecki 1998 theorem; whether NPT bound entanglement exists remains open.
Bound for Glory (1976 film)
Bound for Glory (1976) is Hal Ashby's biopic of folk singer Woody Guthrie, starring David Carradine, from Guthrie's 1943 autobiography. First feature to use the Steadicam; Haskell Wexler won the cinematography Oscar among six nominations and two wins.
Bound for Glory (2024)

Bound for Glory (2025)
Bound for Glory 2025 (BFG 2025) was TNA Wrestling's 21st annual flagship pay-per-view, held October 12, 2025 at the Tsongas Center in Lowell, Massachusetts, where Mike Santana won the TNA World Championship from Trick Williams.
Bound for Glory (2026)
Bound for Glory (2026), TNA Wrestling's 22nd annual flagship pay-per-view, held October 11, 2026 at the Yuengling Center in Tampa, Florida; Leon Slater won the TNA World Championship from Nic Nemeth, and ODB, Amazing Red, and Konnan entered the Hall of Fame.
Bound metal deposition
Bound metal deposition, or BMD, is a metal additive manufacturing process that extrudes binder-bound metal powder rods layer by layer, then debinds and sinters the part in a furnace.
Bound state
A bound state is a quantum state whose particle lacks the energy to escape an attractive potential, giving localized wavefunctions and discrete energy levels, like electrons in atoms.
Bound state in the continuum
A bound state in the continuum is a wave state trapped despite lying in the energy range of radiating states, first proposed by von Neumann and Wigner in 1929.
Bound states in the continuum laser
A bound state in the continuum (BIC) laser is a semiconductor or dielectric laser whose lasing mode stays perfectly confined, enabling high-Q, low-threshold lasing, first demonstrated in 2017.
Bound states in the continuum nanolasers
Bound states in the continuum nanolasers are semiconductor lasers whose lasing mode is a bound state in the continuum, a localized nonradiating state that sharply cuts lasing thresholds.
BoundA 1996 American neo-noir erotic thriller, Bound is the debut feature of the Wachowskis (credited here to Lana Wachowski), and it announces a filmmaker's sensibility already fully formed: cool, controlled, and madly in love with the machinery of genre. The reason to care is simple: it takes the oldest heist setup in the book and runs it through a love story mainstream Hollywood had almost never bothered to film, and it does so with style to burn.
Bound is a 1996 American neo-noir erotic thriller, the debut feature of the Wachowskis, starring Gina Gershon, Jennifer Tilly, and Joe Pantoliano as two women plotting to steal mob money.
Boundaries (band)
Boundaries is an American metalcore band from Hartford, Connecticut, formed around 2013-2015, known for My Body in Bloom, Death Is Little More (2024), and Yearning: The Unbeautiful After (2026) on Sumerian Records.
Boundary (cricket)
Boundary (cricket): the edge of the playing field and the four or six runs scored when the ball reaches it, governed by MCC Law 19, including rope rules, boundary catches, and overthrows.
Boundary and redistricting commissions
A boundary or redistricting commission is a body delegated the task of drawing electoral district boundaries, to stop parties, especially governing ones, from favoring themselves.
Boundary commissions of the United Kingdom
The boundary commissions of the United Kingdom are four independent statutory bodies, one each for England, Scotland, Wales, and Northern Ireland, that periodically redraw parliamentary constituency boundaries.
Boundary conditions and continuity of wave functions
In quantum mechanics, boundary conditions are the continuity rules wave functions must satisfy at potential discontinuities, infinite walls, and delta potentials, determining bound-state energies and scattering.
Boundary control of flexible beams
Boundary control of flexible beams is a control approach in which actuators at a beam's ends regulate vibrations of the entire structure, used in robotic manipulators and spacecraft.
Boundary crossing
Boundary crossing is the work done at a sociocultural boundary to ensure continuity of action or interaction, originating in 1990s learning sciences and organizational studies.
Boundary Dam power station
Boundary Dam power station is a coal-fired power station near Estevan, Saskatchewan, owned by SaskPower; opened in 1959, it became the first commercial coal plant with carbon capture in 2014.
Boundary element method
The boundary element method (BEM) is a numerical technique that solves partial differential equations by discretizing only the domain's boundary, reducing the problem's dimension by one.
Boundary film
A boundary film is a thin protective layer, a few molecular layers thick, that carries the load between rubbing surfaces when the lubricant film can no longer keep them apart.
Boundary integral method
The boundary integral method is a numerical technique that reformulates a partial differential equation as an integral equation on the domain's boundary; discretizing it yields the boundary element method.
Boundary layer
A boundary layer is the thin layer of fluid next to a solid surface where velocity rises from zero at the surface to the free-stream value.
Boundary layer control
Boundary layer control manipulates the thin friction-slowed airflow next to a surface, chiefly by suction or blowing, to delay flow separation and cut aircraft drag.
Boundary layer thickness
Boundary layer thickness is the distance from a solid surface at which a flowing fluid has effectively recovered the free-stream velocity, usually defined where velocity reaches 99% of it.
Boundary lubrication
Boundary lubrication is the tribological regime in which the lubricant film is thinner than the combined surface roughness, so opposing asperities touch and carry the load.
