Mesentery

Mesentery: continuous double fold of peritoneum attaching the intestines to the posterior abdominal wall, carrying vessels, lymphatics, and nerves; redesignated a single organ in 2016, spanning duodenojejunal flexure to anorectal junction.

Meseret Defar

Meseret Defar (መሰረት ደፋር), Ethiopian distance runner born 1983 in Addis Ababa; two-time Olympic 5000m champion (2004, 2012) with 2008 silver, 2007 and 2013 world champion, four-time World Indoor 3000m champion, and former 5000m world record holder.

Meseta Iberica Biosphere Reserve

Meseta Ibérica Transboundary Biosphere Reserve, a UNESCO site since 2015 on the Spain-Portugal border, largest transboundary biosphere reserve in Europe, 1,132,606 ha, run by ZASNET EGTC.

MESFET

A MESFET, or metal-semiconductor field-effect transistor, is a transistor whose metal gate forms a Schottky barrier with the channel, usually in gallium arsenide, enabling operation at microwave frequencies.

Mesh (scale)

Mesh, or mesh size, measures the fineness of woven wire cloth and test sieves by openings per linear inch, with higher numbers passing smaller particles.

Mesh analysis

Mesh analysis, also called the mesh current or loop current method, solves planar electrical circuits by assigning a circulating current to each mesh and applying Kirchhoff's Voltage Law.

Mesh electronics

Mesh electronics is an ultraflexible, macroporous neural probe whose electrodes sit on a tissue-like mesh that integrates with brain tissue rather than piercing it, developed by Charles Lieber's Harvard lab.

Mesh generation

Mesh generation is the computational geometry technique that subdivides a geometric domain into discrete elements such as triangles and tetrahedra, so partial differential equations can be solved by finite element methods.

Mesh hernioplasty

Mesh hernioplasty is the repair of an abdominal wall hernia by reinforcing the defect with synthetic or biologic mesh, so the closure is tension-free rather than sewn tissue alone.

Mesh Invest

Mesh Invest is a venture capital management firm based in Portland, Oregon, investing in electronics such as semiconductors, robotics, and spatial computing, with about $126 million sold across its funds since 2025.

Mesh morphing

Mesh morphing, also called mesh deformation or mesh movement, reshapes a computational mesh by moving its nodes without changing connectivity, used instead of remeshing for moving boundaries and shape optimization.

Mesh network

A mesh network is a network where nodes connect to several other nodes rather than one hub, giving multiple paths so traffic reroutes around failures.

Mesh optimization

Mesh optimization is a family of computational geometry methods that improve polygonal meshes by changing vertex positions, connectivity, and element count, introduced by Hugues Hoppe and colleagues in 1993.

Mesh rectopexy

Mesh rectopexy is a surgical operation that uses a strip of synthetic or biological mesh to fix the rectum to the sacral promontory, treating rectal prolapse.

Mesh shader

A mesh shader is a programmable graphics pipeline stage that processes batches of vertices and primitives before rasterization, introduced by NVIDIA with its Turing architecture in 2018 and supported in Direct3D 12 and Vulkan.

Mesh stiffness

Mesh stiffness is the stiffness of the elastic connection between two meshing gear teeth. It varies periodically with rotation because the number of contacting tooth pairs changes, exciting gear vibration and noise.

Mesh-he

Mesh-he, also read Mes-he, is a smith assigned a 36-year reign in the Sumerian King List as a king of Uruk's First Dynasty, between Ennun-dara-ana and Melem-ana.

Mesh-refinement software frameworks for numerical relativity

Mesh-refinement software frameworks for numerical relativity let codes place fine grids where physics demands them and coarse grids elsewhere, with Carpet the dominant example since 2003.

Mesha

Mesha was a ninth-century BC king of Moab who drove out Israelite occupation and recorded his reign on the Mesha Stele, also called the Moabite Stone.

Mesha Stele

Mesha Stele (Moabite Stone), ninth-century BCE basalt royal inscription by King Mesha of Moab, found at Dhiban 1868, now Louvre AO 5066; names Omri, Chemosh, YHWH; parallels 2 Kings 3; contested line 31 'House of David' reading.

Mesha's revolt

Mesha's revolt, the rebellion of Mesha, king of Moab, against Israelite domination in the mid-9th century BC, ended Moab's vassal status and made Moab an independent kingdom.

Meshach Taylor

Meshach Taylor (1947–2014) was an American actor who played Anthony Bouvier on all seven seasons of Designing Women (1986–93), earning a 1989 Emmy nomination, and Hollywood Montrose in Mannequin (1987).

MeshCore

MeshCore is an open-source firmware project that turns low-cost LoRa radio boards into encrypted, off-grid text-messaging mesh networks using companion, repeater, and room server nodes.

Meshell Ndegeocello

Meshell Ndegeocello, born Michelle Lynn Johnson (1968, Berlin), is an American bassist, singer, and songwriter, pioneer of neo-soul with Plantation Lullabies (1993), and three-time Grammy winner including two Best Alternative Jazz Album awards on Blue Note.
