A fen is one of the main types of wetland, the others being grassy marshes, forested swamps, and peaty bogs. Along with bogs, fens are a kind of mire. Fens are usually fed by mineral-rich surface water or groundwater. They are characterised by their water chemistry, which is pH neutral or alkaline, with relatively high dissolved mineral levels but few other plant nutrients. They are usually dominated by grasses and sedges, and typically have brown mosses in general including Scorpidium or Drepanocladus. Fens frequently have a high diversity of other plant species including carnivorous plants such as Pinguicula. They may also occur along large lakes and rivers where seasonal changes in water level maintain wet soils with few woody plants. The distribution of individual species of fen plants is often closely connected to water regimes and nutrient concentrations.
Fens have a characteristic set of plant species, which sometimes provide the best indicators of environmental conditions. For example, fen indicator species in New York State include Carex flava, Cladium mariscoides, Potentilla fruticosa, Pogonia ophioglossoides and Parnassia glauca.
Car is a surname. Notable people with the surname include:
Car or Kar (Greek: Κάρ) is a name in Greek mythology that refers to two characters who may or may not be one and the same.
The name "Car" is unrelated to the English word "car" (vehicle).
According to Pausanias, Car was the king of Megara and the son of Phoroneus (and Cerdo). His tomb was located on the road from Megara to Corinth. The acropolis at Megara derived its name Caria from him.
Herodotus mentions a (probably) different Car, brother of Lydus and Mysus; the three brothers were believed to have been the ancestral heroes and eponyms of the Carians, the Lydians and the Mysians respectively. This Car was credited by Pliny the Elder with inventing the auspicia.
Car was also said to have founded the city Alabanda, which he named after Alabandus, his son by Callirhoe (the daughter of the river god Maeander). In turn, Alabandus's name is said to have been chosen in commemoration of his Car's victory in a horse fight— according to the scholar Stephanus of Byzantium, "Alabandos" was the Carian word for "winner in a horse fight". Another son of Car, Idrieus, had the city Idrias named after himself.
Structural analogs (structural analogue or simply analog) are models or representations that keep each other certain "structural similarity". It is used in engineering, chemistry, mathematics and other fields.
Despite the field diversity, all structural analog analysis use some level of abstraction to transform models in mathematical graphs, and detected structural analogies by algorithms. Example: for molecular structure comparison and classification operations, the compared compounds are modeled as a mathematical graph. Formally, when structures are represented by graphs, the concept of analog is related to a graph isomorphism.
Analogical models are used in a method of representing a ‘target system’ by another, more understandable or analysable system.
Two systems have analog structures (see illustration) if they are isomorphic graphs and have equivalent (mapped) lumped elements. In Electronics, methods based on fault models of structural analogs gain some acceptance in industry.
Analogy (from Greek ἀναλογία, analogia, "proportion") is a cognitive process of transferring information or meaning from a particular subject (the analogue or source) to another (the target), or a linguistic expression corresponding to such a process. In a narrower sense, analogy is an inference or an argument from one particular to another particular, as opposed to deduction, induction, and abduction, where at least one of the premises or the conclusion is general. The word analogy can also refer to the relation between the source and the target themselves, which is often, though not necessarily, a similarity, as in the biological notion of analogy.
Analogy plays a significant role in problem solving such as, decision making, perception, memory, creativity, emotion, explanation, and communication. It lies behind basic tasks such as the identification of places, objects and people, for example, in face perception and facial recognition systems. It has been argued that analogy is "the core of cognition". Specific analogical language comprises exemplification, comparisons, metaphors, similes, allegories, and parables, but not metonymy. Phrases like and so on, and the like, as if, and the very word like also rely on an analogical understanding by the receiver of a message including them. Analogy is important not only in ordinary language and common sense (where proverbs and idioms give many examples of its application) but also in science, philosophy, and the humanities. The concepts of association, comparison, correspondence, mathematical and morphological homology, homomorphism, iconicity, isomorphism, metaphor, resemblance, and similarity are closely related to analogy. In cognitive linguistics, the notion of conceptual metaphor may be equivalent to that of analogy.
Analog Science Fiction and Fact is an American science fiction magazine. As of 2015, it is the longest running continuously published magazine of that genre, the June 2015 issue being number 1,000. Initially published in 1930 in the United States as Astounding Stories as a pulp magazine, it has undergone several name changes, primarily to Astounding Science-Fiction in 1938, and Analog Science Fact & Fiction in 1960. In November 1992, its logo changed to use the term "Fiction and Fact" rather than "Fact & Fiction". It is in the library of the International Space Station. Spanning three incarnations since 1930, this is perhaps the most influential magazine in the history of the genre. It remains a fixture of the genre today.
As Astounding Science-Fiction, a new direction for both the magazine and the genre under editor John W. Campbell was established. His editorship influenced the careers of Isaac Asimov and Robert A. Heinlein, and also introduced the Dianetics theories of L. Ron Hubbard in May 1950.
