Maximum heart rate

Maximum heart rate is the highest heart rate a person can reach during maximal exertion, which declines with age and is predicted by formulas like 220 minus age.

Maximum intensity projection

Maximum intensity projection (MIP) is a volume rendering technique that projects the brightest voxel value along each viewing ray onto a 2D image, standard for CT and MR angiography.

Maximum life span

Maximum life span is the greatest age reached by any member of a species, distinct from life expectancy; the human record is 122.5 years, with debate over a limit near 115 years, and Greenland sharks reaching about 400 years.

Maximum likelihood channel estimation

Maximum likelihood channel estimation is a method that estimates a communication channel's response by choosing the channel coefficients that maximize the likelihood of the received data samples.

Maximum likelihood detection

Maximum likelihood detection is a digital communications method that selects the transmitted symbol or sequence most likely to explain the received signal, minimizing error when symbols are equally likely.

Maximum likelihood estimation

Maximum likelihood estimation (MLE) is a statistical estimation method that picks parameter values maximizing the likelihood of the observed data, introduced by R. A. Fisher in 1922.

Maximum likelihood expectation maximization

Maximum likelihood expectation maximization (MLEM) is an iterative algorithm for reconstructing images in PET and SPECT emission tomography, introduced by Shepp and Vardi in a 1982 paper.

Maximum likelihood sequence estimation

Maximum likelihood sequence estimation (MLSE) is a digital communications receiver method that estimates an entire symbol sequence, minimizing error on channels with intersymbol interference and Gaussian noise.

Maximum Overdrive

Maximum Overdrive (1986) is Stephen King's only film as director, an adaptation of his short story "Trucks" in which machines turn homicidal; it flopped critically and commercially but gained a cult following via its AC/DC soundtrack, Who Made Who.

Maximum parsimony (phylogenetics)

Maximum parsimony is a phylogenetics method that infers an evolutionary tree by choosing the topology requiring the fewest character-state changes; finding the best tree is NP-complete.

Maximum permissible error

A maximum permissible error, also called a limit of error, is the extreme measurement error that specifications or regulations permit for a given measurement, measuring instrument, or measuring system.

Maximum Pleasure Guaranteed

Maximum Pleasure Guaranteed is a 2026 Apple TV dark comedy thriller created by David J. Rosen, starring Tatiana Maslany as divorced Queens mom Paula, blackmailed after witnessing an attack on a camboy; ten episodes, renewed for Season 2 in October 2026.

Maximum potential intensity

Maximum potential intensity, often called potential intensity, is a theoretical upper limit on the strength a tropical cyclone can reach in a given atmospheric and oceanic environment.

Maximum power point tracking

Maximum power point tracking (MPPT), typically performed by an inverter or DC-DC converter, continuously adjusts a photovoltaic array's operating point to deliver the greatest power available as sunlight and temperature vary.

Maximum power transfer theorem

The maximum power transfer theorem, also called Jacobi's law, states that a source with fixed internal resistance delivers the greatest power when the load resistance equals the source resistance.

Maximum principle

The maximum principle is a collection of theorems for elliptic and parabolic partial differential equations stating that a solution attains its extreme values on the boundary of its domain.

Maximum ratio combining

Maximum ratio combining (MRC) is a diversity reception technique in which a receiver weights independently faded copies of a signal so they add coherently, achieving the highest possible output SNR.

Maximum ratio transmission

Maximum ratio transmission (MRT), also called conjugate beamforming, is a linear precoding technique that aligns each base station transmit signal with the user's channel vector.

Maximum residue limit

The maximum residue limit, or maximum residue level, is the legal ceiling for pesticide residue in or on food, set assuming use under Good Agricultural Practice.

Maximum residue limit harmonization

Maximum residue limit harmonization is the effort by international and regional bodies, including Codex, the OECD, and ASEAN, to align permissible pesticide residue levels in food across countries.

Maximum Ride

Maximum Ride is James Patterson's young adult science fiction series (2005-2015, nine novels) about the Flock, six children engineered as 98% human and 2% avian, led by fourteen-year-old Max, escaping the School and hunted by wolf-human Erasers; adapted as manga, a 2016 film, and Hawk sequels.

Maximum Risk

Maximum Risk is a 1996 American action thriller directed by Ringo Lam, his Hollywood debut, in which Jean-Claude Van Damme plays twin brothers on opposite sides of the law.

Maximum subarray problem

The maximum subarray problem, also called the maximum segment sum problem, asks for a contiguous array stretch with the largest possible sum; Kadane's algorithm solves it in linear time.

Maximum sustained wind

Maximum sustained wind is the highest near-surface wind speed averaged over a defined period, used as the standard measure of a tropical cyclone's intensity; the United States uses a 1-minute average.

Maximum the Hormone (マキシマムザホルモン)

Maximum the Hormone (マキシマムザホルモン, MTH) is a Japanese four-piece rock band formed in 1998 in Hachioji, Tokyo, mixing loud rock with pop melodies; Yoshu Fukushu (2013) topped Oricon for three weeks and total sales exceed 2.2 million.

Maximum tolerated dose

The maximum tolerated dose (MTD) is the highest dose of a drug that can be given without unacceptable toxicity, historically the target of phase I oncology dose-escalation trials.

Maximum transmission unit

The maximum transmission unit (MTU) is the largest packet or frame, measured in octets, that a network link can send in one piece, 1500 bytes for standard Ethernet.

Maximum variation sampling

Maximum variation sampling, also called heterogeneous purposive sampling, is a qualitative research strategy that selects cases differing as much as possible on dimensions set in advance.

Maximum-likelihood MIMO detection

Maximum-likelihood MIMO detection (ML detection, MLD) is the optimal receiver algorithm for MIMO wireless systems, minimizing the Euclidean distance between the received vector and possible transmitted signals.

Maximus (comics)

Maximus Boltagon, or Maximus the Mad, is a Marvel Comics supervillain, younger brother of Inhuman king Black Bolt, debuting in Fantastic Four #47 (1966) by Stan Lee and Jack Kirby, with mind-control powers and a recurring coup plot against Attilan.
