Reghin, Romania
Reghin (; hu, Szászrégen, or ; german: (Sächsisch) Regen) is a city in Mureș County, Transylvania, central Romania, on the Mureș River. As of 2011, it had a population of 33,281.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 Reghin was first mentioned in 1228 in a charter of Hungarian King Andrew II as ''Regun'' – however, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physics
Physics is the natural science that studies matter, its 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." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "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 physic ...

National Science Foundation
The National Science Foundation (NSF) is an independent agency of the United States government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about $8.3 billion (fiscal year 2020), the NSF funds approximately 25% of all federally supported basic research conducted by the United States' colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing. The NSF's director and deputy director are appointed by the President of the United States and confirmed by the United States Senate, whereas the 24 president-appointed members of the National Science Board (NSB) do not require Senate confirmation. The director and deputy director are responsible for administration, planning, budgeting and day-to-day operations of the foundation, while t ...

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. Particularly from the year 2000 onwards, the concept has been used widely in biology in a variety of contexts. The Human Genome Project is an example of applied systems thinking in biology which has led to new, collaborative ways of working on problems in the biological field of genetics. One of the aims of systems biology is to model and discover emergent property, emergent properties, properties of cell (biology), cells, tissue (biology), tissues and organisms functioning as a system whose theoretical description is only possible using techniques of systems biology. These typically involve metabolic networks or cell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 gathered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Grid
An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. It consists of:Kaplan, S. M. (2009). Smart Grid. Electrical Power Transmission: Background and Policy Issues. The Capital.Net, Government Series. Pp. 1-42. * power stations: often located near energy and away from heavily populated areas * electrical substations to step voltage up or down * electric power transmission to carry power long distances * electric power distribution to individual customers, where voltage is stepped down again to the required service voltage(s). Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same time). This allows transmission of AC power throughout the area, connecting a large number of electricity generators and consumers and potential ...

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 process, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mureș County
Mureș County (, ro, Județul Mures, hu, Maros megye) is a county ('' județ'') of Romania, in the 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 ''judeţ'' (county) system, still used today. This reform eliminated the previous 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 Hungarian-speaking Székelys and Transylvanian Saxons, with a rich heritage of fortified churches and towns. Name In Hungarian, it is known as ''Maros megye'' (), and in German as ''Kreis Mieresch''. Under Kingdom of Hungary, a county with an similar name (Maros-Torda County, ro, Comitatul Mureş-Turda) was created in 1876. There was a county with the same name under the Kingdom of Romania, and a Mureș-Magyar Autonomous Region (1960–19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
