Leptotyphlops

Leptotyphlops is a genus of nonvenomous blind snakes, commonly known as slender blind snakes and threadsnakes, found throughout North and South America, Africa, India and southwestern Asia. Currently, 86 species are recognized.

Description

Most species look much like shiny earthworms. They are pink or brown, and their scales give them a segmented appearance. Other species are black in color, but have the same general body structure. Their common name comes from the fact that their eyes are greatly reduced almost to the point of uselessness, and hidden behind a protective head scale. The species which are called thread snakes are so named because of their very narrow, long bodies.

Geographic range

Found in the Americas, Africa, India and southwestern Asia. In the Americas from the southwestern United States, south through most of Central and South America as far as Uruguay and Argentina. Also found on San Salvador Island in the Bahamas, in Haiti, the Dominican Republic and in the Lesser Antilles. Also found on Socotra Island.

Connected (Ayumi Hamasaki song)

"Connected" is a song recorded by Japanese recording artist and lyricist Ayumi Hamasaki for her fourth studio album I Am..., released on January 1, 2002. The song was written by Hamasaki herself while it was produced by Dutch disc jockey Ferry Corsten. The song was first conceived when Corsten had developed a track in Europe entitled "The Lost of Love". Despite him playing it at several events and shows throughout Europe, he did not release the track. After this, Hamasaki and Corsten had started to collaborate and the pair had changed and used the finishing result to create "Connected".

Musically, "Connected" is a trance song that utilizes electro and dance music, which was a prominent musical genre during early 2000s. The song achieved favorable reception from most music critics, who had praised the musical collaboration and electronic influence within the album. However, some critics were divided by the lack of progression and Hamasaki's vocal abilities. Being released in Europe in April 2003 as her first European single, the song did not chart in any important record charts neither did it chart on Oricon. An accompanying music video was shot for the single by Kouji Morimoto and featured anime inspired themes and features people in a futuristic city.

Connectivity (graph theory)

In mathematics and computer science, connectivity is one of the basic concepts of graph theory: it asks for the minimum number of elements (nodes or edges) that need to be removed to disconnect the remaining nodes from each other. It is closely related to the theory of network flow problems. The connectivity of a graph is an important measure of its robustness as a network.

Connected graph

A graph is connected when there is a path between every pair of vertices. In a connected graph, there are no unreachable vertices. A graph that is not connected is disconnected.
A graph with just one vertex is connected. An edgeless graph with two or more vertices is disconnected.

Definitions of components, cuts and connectivity

In an undirected graph G, two vertices u and v are called connected if G contains a path from u to v. Otherwise, they are called disconnected. If the two vertices are additionally connected by a path of length 1, i.e. by a single edge, the vertices are called adjacent. A graph is said to be connected if every pair of vertices in the graph is connected.
