The Ramnulfids, or the House of Poitiers, were a French dynasty of Frankish origin ruling the County of Poitou and Duchy of Aquitaine in the 9th through 12th centuries. Their power base shifted from Toulouse to Poitou. In the early 10th century, they contested the dominance of northern Aquitaine and the ducal title to the whole with the House of Auvergne. In 1032, they inherited the Duchy of Gascony, thus uniting it with Aquitaine. By the end of the 11th century, they were the dominant power in the southwestern third of France. The founder of the family was Ramnulf I, who became count in 835.

The Archdiocese of Poitiers is a Latin archdiocese of the Catholic Church in France. The archepiscopal see is in the city of Poitiers. The Diocese of Poitiers includes the two Departments of Vienne and Deux-Sèvres.

The University of Limoges is a French public university, based in Limoges. Its chancellor is the rector of the Academy of Limoges. It counts more than 16,000 students and near 1,000 scholars and researchers. It offers complete curricula up to the doctorates and beyond in the traditional areas of knowledge. It was structured in October 1968 by the grouping of higher education institutions in Limoges. The oldest historical continuity is that of the faculties of pharmacy and medicine dating back to 1626.
Abderrazak El Albani is a French-Moroccan sedimentologist, professor at University of Poitiers at the Hydrasa laboratory. He is known for describing the "Francevillian Biota" from the Paleoproterozoic of Gabon, which he suggests represents the oldest known multicellular organisms, though this claim has been questioned by other authors.
The IC2MP is a multidisciplinary French joint research unit of the University of Poitiers (France) and the CNRS.
The CNRS Silver Medal is a scientific award given every year to about fifteen researchers by the French National Centre for Scientific Research (CNRS). It is awarded to a researcher for "the originality, quality and importance of their work, recognised on a national and international level".

fastText is a library for learning of word embeddings and text classification created by Facebook's AI Research (FAIR) lab. The model allows one to create an unsupervised learning or supervised learning algorithm for obtaining vector representations for words. Facebook makes available pretrained models for 294 languages. Several papers describe the techniques used by fastText.
The Revue Européenne des Migrations Internationales is a quarterly peer-reviewed academic journal published by the University of Poitiers with support from the French National Centre for Scientific Research (CNRS). Articles can be freely accessed via the OpenEdition Journals platform after a one-year embargo period. The main publication languages are French and English, the abstracts are also available in Spanish. Issues published prior to 2002 are available via Persée.
Diffusive–thermal instability or thermo–diffusive instability is an intrinsic flame instability that occurs both in premixed flames and in diffusion flames and arises because of the difference in the diffusion coefficient values for the fuel and heat transport, characterized by non-unity values of Lewis numbers. The instability mechanism that arises here is the same as in Turing instability explaining chemical morphogenesis, although the mechanism was first discovered in the context of combustion by Yakov Zeldovich in 1944 to explain the cellular structures appearing in lean hydrogen flames. Quantitative stability theory for premixed flames were developed by Gregory Sivashinsky (1977), Guy Joulin and Paul Clavin (1979) and for diffusion flames by Jong S. Kim and Forman A. Williams (1996,1997).
In combustion, Michelson–Sivashinsky equation describes the evolution of a premixed flame front, subjected to the Darrieus–Landau instability, in the small heat release approximation. The equation was derived by Gregory Sivashinsky in 1977, who along the Daniel M. Michelson, presented the numerical solutions of the equation in the same year. Let the planar flame front, in a uitable frame of reference be on the -plane, then the evolution of this planar front is described by the amplitude function describing the deviation from the planar shape. The Michelson–Sivashinsky equation, reads as
