Banksia is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes and fruiting "cones" and heads. Banksias range in size from prostrate woody shrubs to trees up to 30 metres tall. They are found in a wide variety of landscapes; sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts.
Fan-Rong King Chung Graham, known professionally as Fan Chung, is a Taiwanese-born American mathematician who works mainly in the areas of spectral graph theory, extremal graph theory and random graphs, in particular in generalizing the Erdős–Rényi model for graphs with general degree distribution.
Phossy jaw, formally known as phosphorus necrosis of the jaw, was an occupational disease affecting those who worked with white phosphorus without proper safeguards. It was most commonly seen in workers in the matchstick industry in the 19th and early 20th centuries. It was caused by white phosphorus vapour, which destroys the bones of the jaw. Modern occupational hygiene practices have since eliminated the working conditions that caused this disease.
In computer science, graph transformation, or graph rewriting, concerns the technique of creating a new graph out of an original graph algorithmically. It has numerous applications, ranging from software engineering to layout algorithms and picture generation.
"The Little Match Girl" is a short story by Danish poet and author Hans Christian Andersen. The story, about a dying child's dreams and hope, was first published in 1845. It has been adapted to various media, including an animated short film, a television musical, and an animated virtual reality story called "Allumette".
Banksia subg. Isostylis is a subgenus of Banksia. It contains three closely related species, all of which occur only in Southwest Western Australia. Members of subgenus Isostylis have dome-shaped flower heads that are superficially similar to those of B. ser. Dryandra, but structurally more like reduced versions of the "flower spikes" characteristic of most other Banksia taxa.
Banksia cuneata, commonly known as matchstick banksia or Quairading banksia, is an endangered species of flowering plant in the family Proteaceae. Endemic to southwest Western Australia, it belongs to Banksia subg. Isostylis, a sub-genus of three closely related Banksia species with inflorescences or flower clusters that are dome-shaped heads rather than characteristic Banksia flower spikes. A shrub or small tree up to 5 m (16 ft) high, it has prickly foliage and pink and cream flowers. The common name Matchstick Banksia arises from the blooms in late bud, the individual buds of which resemble matchsticks. The species is pollinated by honeyeaters (Meliphagidae).
Matchstick Productions, also known as MSP Films, is a film production company based in Crested Butte, Colorado that specializes in producing ski movies. Steve Winter and Murray Wais founded the company in 1992. According to MSP’s website, “Matchstick aims to create entertaining films that not only are stunning visually but on the cutting edge of action sports.”
207 is the natural number following 206 and preceding 208.
The genus Banksia L.f. (Proteaceae) is a 1981 monograph by Alex George on the taxonomy of the plant genus Banksia. Published by the Western Australian Herbarium as Nuytsia 3(3), it presented George's taxonomic arrangement of Banksia, the first major taxonomic revision of the genus since George Bentham published his arrangement in Flora Australiensis in 1870.
The Little Matchgirl is a 2006 animated short film produced by Walt Disney Animation Studios and released by Walt Disney Pictures, directed by Roger Allers and produced by Don Hahn. It is based on an original story of the same name by Hans Christian Andersen, published in 1845.
LivePlanet is a production company that invests in content for television and new media platforms. It was founded in 2000.
In graph theory, a star Sk is the complete bipartite graph K1,k: a tree with one internal node and k leaves. Alternatively, some authors define Sk to be the tree of order k with maximum diameter 2; in which case a star of k > 2 has k − 1 leaves.
Eric Hjorleifson is a professional freeskier. He was born and raised in Canmore, Alberta. Hjorleifson contributes yearly to ski movies made by the film company Matchstick Productions. Eric creates the design and graphics for a line of skis for 4FRNT.
Ingrid Backstrom is an internationally ranked professional skier from Seattle, Washington. Born August 21, 1978, Backstrom graduated from Whitman College in 2000 with a Bachelor of Arts in Geology. Her brother, Arne Backstrom, died in a skiing accident in 2010 at the age of 29.
In computing, a graph database (GDB) is a database that uses graph structures for semantic queries with nodes, edges and properties to represent and store data. A key concept of the system is the graph, which directly relates data items in the store a collection of nodes of data and edges representing the relationships between the nodes. The relationships allow data in the store to be linked together directly, and in many cases retrieved with one operation. Graph databases hold the relationships between data as a priority. Querying relationships within a graph database is fast because they are perpetually stored within the database itself. Relationships can be intuitively visualized using graph databases, making it useful for heavily inter-connected data.
The FKT algorithm, named after Fisher, Kasteleyn, and Temperley, counts the number of perfect matchings in a planar graph in polynomial time. This same task is #P-complete for general graphs. Counting the number of matchings, even for planar graphs, is also #P-complete. The key idea is to convert the problem into a Pfaffian computation of a skew-symmetric matrix derived from a planar embedding of the graph. The Pfaffian of this matrix is then computed efficiently using standard determinant algorithms.
