Stefan Popov (born 3rd of April 1940) is a cellist who holds Bulgarian nationality.
 He started to learn to play the cello at the age of 9 and, having won a scholarship, continued his training at the Moscow Conservatory where he studied under Sviatoslav Knushevitsky and Mstislav Rostropovich from 1961 to 1966.
 He became a prize-winner in many competitions, including Geneva, Florence and Vienna.
 In 1966, as a finalist he won a medal in the International Tchaikovsky Competition for Cello.
 At the same time as the Tchaikovsky competition, he was also awarded a prize from the Union of Soviet Composers for his performance of Russian music.
In narrative theory, actant is a term from the actantial model of semiotic analysis of narratives.
 The term also has uses in linguistics, sociology, computer programming theory, and astrology.
In structural semantics, the actantial model, also called the actantial narrative schema, is a tool used to analyze the action that takes place in a story, whether real or fictional.
 It was developed in 1966 by semiotician Algirdas Julien Greimas.
The Unified Model is a Numerical Weather Prediction and climate modeling software suite originally developed by the United Kingdom Met Office, and now both used and further developed by many weather-forecasting agencies around the world.
 The Unified Model gets its name because a single model is used across a range of both timescales (nowcasting to centennial) and spatial scales (convective scale to climate system earth modelling).
 The models are grid-point based, rather than wave based, and are run on a variety of supercomputers around the world.
 The Unified Model atmosphere can be coupled to a number of ocean models.
 At the Met Office it is used for the main suite of Global Model, North Atlantic and Europe model (NAE) and a high-resolution UK model (UKV), in addition to a variety of Crisis Area Models and other models that can be run on demand.
 Similar Unified Model suites with global and regional domains are used by many other national or military weather agencies around the world for operational forecasting.
Algirdas Julien Greimas (] ; born "Algirdas Julius Greimas"; 9 March 1917 – 27 February 1992), was a French-Lithuanian literary scientist, known among other things for the Greimas Square ("le carré sémiotique").
 He is, along with Roland Barthes, considered the most prominent of the French semioticians. With his training in structural linguistics, he added to the theory of signification and laid the foundations for the Parisian school of semiotics.
 Among Greimas's major contributions to semiotics are the concepts of isotopy, the actantial model, the narrative program, and the semiotics of the natural world.
 He also researched Lithuanian mythology and Proto-Indo-European religion, and was influential in semiotic literary criticism.
Sociofact is a term coined by Sir Julian Sorell Huxley, used together with the related terms "mentifact" (sometimes called a psychofact) and "artifact" to describe how cultural traits take on a life of their own, spanning over generations.
 This idea has been related to memetics.
 The idea of the sociofact was developed extensively by David Bidney in his textbook "Theoretical Anthropology".
 Bidney used the term to refer to objects which consist of interactions between members of a social group.
 The concept has been used by philosophers and social scientists in their analyses of varying kinds of social groups.
 For instance, semiotician of music Charles Boilès, in a discussion of the semiotics of the tune "Taps", claims that although it is a single piece of music, it can be seen as three distinct musical sociofacts: as a "last call" signal in taverns frequented by soldiers, as an "end of day" signal on military bases, and hence symbolically as a component of military funerals.
 The claim has been made that sociofactual analysis can play a decisive role for the performance of, and collaboration within, organizations.
Guillermo Huerta Huitrón (born July 3, 1966 in Mexico City) is a Mexican football manager and former player.
 He was born in the (Distrito Federal) Federal District, or DF, in Mexico, and is of Mexican Nationality.
The Dynamic Integrated Climate-Economy model, referred to as the DICE model or Dice model, is a computer-based integrated assessment model developed by William Nordhaus that “integrates in an end-to-end fashion the economics, carbon cycle, climate science, and impacts in a highly aggregated model that allows a weighing of the costs and benefits of taking steps to slow greenhouse warming."
 Nordhaus also developed the RICE model (Regional Integrated Climate-Economy model), a variant of the DICE model that was updated and developed alongside the DICE model.
 Others who collaborated with Nordhaus to develop the model include David Popp, Zili Yang, Joseph Boyer, and other colleagues.
The Donabedian model is a conceptual model that provides a framework for examining health services and evaluating quality of health care.
 According to the model, information about quality of care can be drawn from three categories: “structure,” “process,” and “outcomes."
 Structure describes the context in which care is delivered, including hospital buildings, staff, financing, and equipment.
 Process denotes the transactions between patients and providers throughout the delivery of healthcare.
 Finally, outcomes refer to the effects of healthcare on the health status of patients and populations.
 Avedis Donabedian, a physician and health services researcher at the University of Michigan, developed the original model in 1966.
 While there are other quality of care frameworks, including the World Health Organization (WHO)-Recommended Quality of Care Framework and the Bamako Initiative, the Donabedian Model continues to be the dominant paradigm for assessing the quality of health care.
Jaroslav Volek (15 July 1923, Trenčín – 23 February 1989, Prague) was a Czech musicologist, semiotician who developed a theory of modal music.
 His theory included ideas of poly-modality and alteration of notes that he called "flex," which result in what he called the system of flexible diatonics.
 He applied this theory to the work of Béla Bartók and Leoš Janáček.
 He wrote "General Theory of Art" based on semiotic concepts in 1968.
