Materialize CSS
Materialize CSS is a responsive front-end CSS framework based on Google's Material Design, created in 2014, with components such as cards, modals, tabs, a carousel, and a 12-column grid.
Materialized view
A materialized view is a database object that stores a query's result as data instead of computing it each time, like a cache that must be kept consistent with the base tables.
Materials Characterization
Materials Characterization is the set of experimental techniques that determine a material's structure, composition, and properties by probing samples with electrons, X-rays, neutrons, or heat; the name also belongs to an Elsevier journal published since 1990.
Materials Cloud
Materials Cloud is an open-access web platform, online since 2017, for sharing data, tools, and educational materials in computational materials science, operated by EPFL in Switzerland.
Materials Genome Initiative
The Materials Genome Initiative is a United States federal multi-agency initiative, launched in 2011, that aims to halve the time and cost of developing advanced materials.
Materials informatics
Materials informatics is the application of data science and machine learning to materials discovery, a field that grew rapidly after the 2011 US Materials Genome Initiative.
Materials management
Materials management is the coordinating function that plans and controls the flow of materials through an organization, from purchasing and storage through production to delivery to the customer.
Materials Project
The Materials Project is a free, web-based database of computed properties of inorganic crystals and molecules, operated by Lawrence Berkeley National Laboratory to speed materials discovery since 2011.
Materials Research Society
The Materials Research Society (MRS), founded in 1973 and based in Warrendale, Pennsylvania, is a professional society for materials researchers with about 15,000 members in over 90 countries.
Materials science
Materials science, also called materials science and engineering, studies the structure and properties of materials such as metals, ceramics, polymers, and semiconductors to improve their performance.
Materials Science and Technology (journal)
Materials Science and Technology is a peer-reviewed journal covering the fundamental and technological aspects of materials science, launched in January 1985 by the Institute of Metals and published by Taylor & Francis.
Materials Studio
Materials Studio is a commercial modeling and simulation software environment for materials science and chemistry, sold by Dassault Systèmes under the BIOVIA brand and first released in 2000.
Matérn covariance function
The Matérn covariance function, or Matern kernel, is a parametric family of covariance functions describing correlation in random fields, widely used in spatial statistics, geostatistics, and machine learning.
Maternal Age
Maternal age is the mother's age at delivery; advanced maternal age means 35 or older. US mean age at childbirth rose to 29.5 years (2022); older age raises aneuploidy, miscarriage, stillbirth, and cesarean risks.
Maternal bond
Maternal bond: the mother's emotional connection to her child, distinct from infant attachment. Measured by tools like the Postpartum Bonding Questionnaire; rooted in oxytocin and dopamine systems; disrupted by postpartum depression.
Maternal care for disproportion
Maternal care for disproportion (ICD-11 JA83; ICD-10 O33) covers care when the fetus is known or suspected too large for the maternal pelvis (cephalopelvic disproportion), its subtypes, diagnosis by trial of labor, and management.
Maternal death
Maternal death: death of a woman while pregnant or within 42 days of pregnancy's end from pregnancy-related causes, measured as the MMR per 100,000 live births; global MMR fell from 328 (2000) to 197 (2023), with about 260,000 deaths in 2023.
Maternal health
Maternal health covers women's health during pregnancy, childbirth and the postnatal period. Global MMR fell 40% to 197 per 100,000 live births in 2023, with 260,000 deaths, versus SDG target 70.
Maternal hypotension syndrome
Maternal hypotension syndrome (ICD-11 JA65.6), chiefly supine hypotensive syndrome: gravid-uterus compression of the inferior vena cava when lying supine in late pregnancy, causing hypotension in about 8% of third-trimester pregnancies, relieved by left lateral tilt.
Maternal immune activation
Maternal immune activation (MIA) is an experimental paradigm in which pregnant animals are exposed to immune-stimulating agents to model prenatal inflammation's effects on offspring brain development.
Maternal Inheritance
Maternal inheritance: transmission of genetic traits solely from the mother via extra-nuclear elements such as mitochondrial DNA and maternal mRNA; non-Mendelian, female-line transmission with heteroplasmy and threshold effects.
Maternal phenylketonuria syndrome
Maternal phenylketonuria syndrome (maternal PKU syndrome, MPKUS) is a pattern of birth defects in babies of pregnant women with PKU, caused by high phenylalanine crossing the placenta.
Maternal riboflavin deficiency
Maternal riboflavin deficiency (ORPHA:411712, OMIM 615026) is a rare autosomal dominant SLC52A1 (RFVT1) disorder causing persistently low maternal vitamin B2, hyperemesis gravidarum, and transient life-threatening MADD in the newborn, corrected with riboflavin.
Maternal separation
Maternal separation is a rodent early-life stress paradigm in which pups are repeatedly removed from their mother, typically 1–6 hours daily, to study lasting effects of early adversity.
Maternal serum screening
Maternal serum screening is a blood test performed during pregnancy that measures fetal and placental proteins to estimate the risk of chromosomal abnormalities and open neural tube defects.
Maternal uniparental disomy of chromosome 20 syndrome
Maternal uniparental disomy of chromosome 20 syndrome (UPD(20)mat, Mulchandani-Bhoj-Conlin syndrome): a very rare imprinting disorder where both chromosome 20 copies come from the mother, causing IUGR, short stature, and severe feeding difficulties.
Maternally inherited diabetes and deafness
Maternally inherited diabetes and deafness (MIDD), also called Ballinger-Wallace syndrome, is a mitochondrial DNA disorder, usually m.3243A>G in MT-TL1, causing diabetes plus progressive hearing loss, inherited only from mothers, in about 1% of diabetes cases.
Maternity Benefit (Amendment) Act, 2017
A 2017 Act of the Indian Parliament amending the Maternity Benefit Act, 1961, extending paid maternity leave to 26 weeks for the first two children.
Maternity Hospitals
Maternity hospitals, historically called lying-in hospitals, are hospitals specializing in care for women during pregnancy and childbirth. Key facts: Göttingen 1751 origin, rooming-in, birth center alternatives, US rural ward closures.
Maternum
Maternum (map form Materno), a lost Roman road station in Etruria on the Via Clodia, 12 miles from Tuscana and 18 from Saturnia, known only from the Tabula Peutingeriana and the Ravenna geographer; site sought at Farnese, Valentano, or Ischia di Castro.
