Reghin, Romania
Reghin (; , or ; ; Transylvanian Saxon: ''Reen'') is a city in Mureș County, Transylvania, central Romania, on the Mureș River. As of 2021, it had a population of 29,742, making it the second biggest city of the Mureș county, just behind the capital Târgu Mureș and ahead of Sighișoara.Rezultatele finale ale Recensământului din 2011: Location Reghin lies north-northeast of Târgu Mureș, extending on both shores of the river Mureș, at the confluence with the Gurghiu River. It was created by the 1926 union of the German-inhabited (formerly Szászrégen) and the Hungarian-inhabited (formerly Magyarrégen) city, and later joined with the two smaller communities of Apalina (Hungarian: ''Abafája''; German: ''Bendorf'') and Iernuțeni (Hungarian: ''Radnótfája''; German: ''Etschdorf''), added in 1956. Formally, the latter two are separate villages administered by the city. The city is on the Târgu Mureș– Deda–Gheorgheni Romanian Railways line 405. History ...

Physics
Physics is the scientific study of matter, its Elementary particle, fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." It is one of the most fundamental scientific disciplines. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (...) You will come to see physics as a towering achievement of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systems Biology
Systems biology is the computational modeling, computational and mathematical analysis and modeling of complex biological systems. It is a biology-based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach (holism instead of the more traditional reductionist, reductionism) to biological research. This multifaceted research domain necessitates the collaborative efforts of chemists, biologists, mathematicians, physicists, and engineers to decipher the biology of intricate living systems by merging various quantitative molecular measurements with carefully constructed mathematical models. It represents a comprehensive method for comprehending the complex relationships within biological systems. In contrast to conventional biological studies that typically center on isolated elements, systems biology seeks to combine different biological data to create models that illustrate and elucidate the dynamic interactions with ...

Modelling Biological Systems
Modelling biological systems is a significant task of systems biology and mathematical biology. Computational systems biology aims to develop and use efficient algorithms, data structures, visualization and communication tools with the goal of computer modelling of biological systems. It involves the use of computer simulations of biological systems, including cellular subsystems (such as the networks of metabolites and enzymes which comprise metabolism, signal transduction pathways and gene regulatory networks), to both analyze and visualize the complex connections of these cellular processes. An unexpected emergent property of a complex system may be a result of the interplay of the cause-and-effect among simpler, integrated parts (see biological organisation). Biological systems manifest many important examples of emergent properties in the complex interplay of components. Traditional study of biological systems requires reductive methods in which quantities of data are gathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Grid
''Power Grid'' is the English-language version of the second edition of the multiplayer German-style board game ''Funkenschlag'', designed by Friedemann Friese and first released in 2004. ''Power Grid'' was released by Rio Grande Games. In the game, each player represents a company which owns power plants and tries to supply electricity to cities. During the game, players bid on power plants and buy resources to provide electricity to the growing number of cities in their network. Background ''Power Grid'' was developed from ''Funkenschlag'', the original game, which had players draw their networks with crayons instead of playing on a fixed map. This and other changes were made when Friedemann Friese reworked the game. The new game is called ''Funkenschlag'' in the German market, but is sold under other names elsewhere. Game play The game comes with a double-sided board with a map of the United States on one side and Germany on the other. Each map has six regions, conta ...

Preferential Attachment
A preferential attachment process is any of a class of processes in which some quantity, typically some form of wealth or credit, is distributed among a number of individuals or objects according to how much they already have, so that those who are already wealthy receive more than those who are not. "Preferential attachment" is only the most recent of many names that have been given to such processes. They are also referred to under the names Yule process, cumulative advantage, the rich get richer, and the Matthew effect. They are also related to Gibrat's law. The principal reason for scientific interest in preferential attachment is that it can, under suitable circumstances, generate power law distributions. If preferential attachment is non-linear, measured distributions may deviate from a power law. These mechanisms may generate distributions which are approximately power law over transient periods. Definition A preferential attachment process is a stochastic urn p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert-László Barabási
Albert-László Barabási (born March 30, 1967) is a Romanian-born Hungarian-American physicist, renowned for his pioneering discoveries in network science and network medicine. He is a distinguished university professor and Robert Gray Professor of Network Science at Northeastern University, holding additional appointments at the Department of Medicine, Harvard Medical School and the Department of Network and Data Science at Central European University. Barabási previously served as the former Emil T. Hofmann Professor of Physics at the University of Notre Dame and was an associate member of the Center of Cancer Systems Biology (CCSB) at the Dana–Farber Cancer Institute, Harvard University. In 1999 Barabási discovered the concept of scale-free networks and proposed the Barabási–Albert model, which explains the widespread emergence of such networks in natural, technological and social systems, including the World Wide Web and online communities.

Mureș County
Mureș County (, , ) is a county (''județ'') of Romania, in the Historical regions of Romania, historical region of Transylvania, with the administrative centre in Târgu Mureș. The county was established in 1968, after the administrative reorganization that re-introduced the historical ''județ'' (Counties of Romania, county) system, still used today. This reform eliminated the previous Magyar Autonomous Region, Mureș-Magyar Autonomous Region, which had been created in 1952 within the People's Republic of Romania. Mureș County has a vibrant multicultural fabric that includes Székely Land, Hungarian-speaking Székelys and Transylvanian Saxons, with a rich heritage of Villages with fortified churches in Transylvania, fortified churches and towns. Name In Hungarian language, Hungarian, it is known as ''Maros megye'' (), and in German language, German as ''Kreis Mieresch''.
