Methionine sulfoximine
Methionine sulfoximine (MSO) is a non-proteinogenic amino acid and the first and most widely used inhibitor of glutamine synthetase, used experimentally and causing convulsions in animals.
Method of analytic tableaux
The method of analytic tableaux, also called semantic tableaux, is a tree-shaped proof procedure for logic introduced by Evert Beth and Jaakko Hintikka in 1955, testing satisfiability by searching for counterexamples.
Method of averaging
The method of averaging, or Krylov–Bogoliubov–Mitropolski method, is a perturbation technique for differential equations with a small parameter and rapidly oscillating terms, replacing the exact equation by an averaged one.
Method of characteristics
The method of characteristics, also known as the Charpit method, solves first-order partial differential equations by reducing them to ordinary differential equations along characteristic curves.
Method of fundamental solutions
The method of fundamental solutions (MFS), also known as the charge simulation method, is a meshfree boundary-type numerical method for PDEs, introduced by Kupradze and Aleksidze in 1964.
Method of image charges
The method of image charges, also called the method of mirror charges, is an electrostatics tool that replaces conductors with fictitious image charges satisfying boundary conditions.
Method of images
The method of images is an electrostatics technique, first presented in 1849 by William Thomson, that replaces conducting surfaces with fictitious image charges satisfying the boundary conditions.
Method of lines
The method of lines is a numerical technique for solving time-dependent partial differential equations: space is discretized, time is left continuous, yielding a system of ODEs.
Method of moments (statistics)
The method of moments is a statistical estimation technique introduced by Karl Pearson in 1894 that equates sample moments to population moments to estimate distribution parameters.
Method of moments quantile regression
Method of moments quantile regression (MM-QR) is a statistical method that fits quantile regression models by matching sample moments, introduced by Machado and Santos Silva in 2019.
Method of steepest descent (asymptotics)
The method of steepest descent, also called the saddle-point method, estimates contour integrals of analytic functions with a large parameter by deforming the contour through a saddle point.
Method of undetermined coefficients
The method of undetermined coefficients is a technique for solving nonhomogeneous linear ODEs with constant coefficients: guess a trial particular solution matching the forcing, then solve for its coefficients by substitution.
Methodology
Methodology is the system of methods and principles used to perform an activity; in research, it is the framework explaining how a problem is investigated and why.
Methods of detecting exoplanets
Methods of detecting exoplanets are the observational techniques astronomers use to find planets around other stars. Most detections are indirect, through transit photometry, radial velocity, astrometry, microlensing, and direct imaging.
Methone (moon)
Methone (Saturn XXXII) is a small moon of Saturn about 3 kilometers across that orbits between Mimas and Enceladus and was discovered in Cassini images in 2004.
Methoxamine
Methoxamine is a synthetic sympathomimetic amine used as the vasopressor methoxamine hydrochloride to raise blood pressure during anesthesia, formerly sold as Vasoxyl and discontinued in the United States.
Methoxetamine
Methoxetamine, also known as Mexxy, is a synthetic ketamine analog dissociative drug first identified in the United Kingdom in 2010 and internationally controlled in 2016.
Methyl acetate
Methyl acetate, also called methyl ethanoate, is a colorless, flammable ester liquid with a fruity odor, used as a solvent for resins, oils, and lacquers.
Methyl acrylate
Methyl acrylate, also known as methyl propenoate, is the methyl ester of acrylic acid, a volatile, highly flammable liquid produced in large volumes as a monomer for acrylic and modacrylic fibers.
Methyl anthranilate
Methyl anthranilate, also called methyl 2-aminobenzoate, is a volatile ester with a strong grape-like odor, the chief compound in artificial grape flavoring and a commercial bird repellent.
Methyl benzoate
Methyl benzoate is the benzoate ester of benzoic acid and methanol, a colorless liquid with a sweet, balsamic, spicy floral odor, found naturally in flowers and fruits.
Methyl beta-cyclodextrin
Methyl beta-cyclodextrin (MβCD) is a methylated, water-soluble derivative of beta-cyclodextrin, a cyclic seven-glucose sugar. It is the standard reagent for depleting cholesterol from cell membranes and a solubilizing excipient in drugs.
Methyl bromide
Methyl bromide, also known as bromomethane, is an odorless gas long used to fumigate soil and shipments against pests, phased out by 2005 for depleting ozone.
Methyl butyrate
Methyl butyrate, also known as methyl butanoate, is the methyl ester of butyric acid, a volatile liquid with a fruity apple and pineapple odor used in flavorings.
Methyl cellulose
Methyl cellulose (Citrucel) is a cellulose ether that dissolves in cold water and gels when heated, used as a food thickener, drug excipient, and mortar additive.
Methyl chloride
Methyl chloride, also called chloromethane (CH₃Cl), is a colorless, toxic, flammable gas and the most prevalent organochlorine compound in the atmosphere, produced mostly by natural sources like oceans and biomass burning.
Methyl cinnamate
Methyl cinnamate is the methyl ester of cinnamic acid, a white crystalline solid with formula C10H10O2 and a strawberry-like, balsamic odor used as a flavoring and fragrance.
Methyl decanoate
Methyl decanoate (methyl caprate, CAS 110-42-9), C11H22O2, the methyl ester of capric acid; a colorless liquid found in cheeses and hops, used as flavoring agent and insect attractant, EU pesticide approval expired 31 August 2024.
