SUMMARY / RELATED TOPICS

Heteroatom

In chemistry, a heteroatom is any atom, not carbon or hydrogen. In practice, the term is used more to indicate that non-carbon atoms have replaced carbon in the backbone of the molecular structure. Typical heteroatoms are nitrogen, sulfur, chlorine and iodine, as well as the metals lithium and magnesium, it can be used with specific meanings in specialised contexts. In the description of protein structure, in particular in the Protein Data Bank file format, a heteroatom record describes an atom as belonging to a small molecule cofactor rather than being part of a biopolymer chain. In the context of zeolites, the term heteroatom refers to partial isomorphous substitution of the typical framework atoms by other elements such as beryllium and chromium; the goal is to adjust properties of the material to optimize the material for a certain application.

Chains of Love (Erasure song)

"Chains of Love" is a song by British synthpop duo Erasure, released in May 1988 as their ninth single overall. The song was released by Mute Records as the second single from Erasure's third studio album The Innocents. In the United States, Sire Records released it as the first single; the album version was produced by Stephen Hague and was remixed for its single release. "Chains of Love" became Erasure's sixth consecutive Top 20 hit on the UK singles chart, just missing the Top 10 by peaking at number 11. In the United States, it became Erasure's mainstream breakthrough by climbing to number 12 on the Billboard Hot 100 and becoming the group's first entry on the Modern Rock Tracks chart, it hit number four on the U. S. Hot Dance Music/Club Play chart. "Chains of Love" remains Erasure's highest-charting single in the United States. The song, written by Vince Clarke and Andy Bell, is an uptempo dance-oriented synthpop track with Clarke's signature analogue sound and Bell's lyrics about breaking through any restrictions or stereotypes of what love should be.

The lyrics allude subtly to Bell's desire for wider acceptance of gay couples, his pain evident from the opening lines "How can I explain when there are few words I can choose/How can I explain when words get broken". The chorus is memorable for Bell's use of falsetto; the music video featured Clarke and Bell performing the song while being hoisted through the air by thick, metal chains.

Tournament sort

Tournament sort is a sorting algorithm. It improves upon the naive selection sort by using a priority queue to find the next element in the sort. In the naive selection sort, it takes O operations to select the next element of n elements. Tournament sort is a variation of heapsort. Tournament replacement selection sorts are used to gather the initial runs for external sorting algorithms. Conceptually, an external file is read and its elements are pushed into the priority queue until the queue is full; the minimum element is pulled from the queue and written as part of the first run. The next input element is read and pushed into the queue, the min is selected again and added to the run. There's a small trick that if the new element being pushed into the queue is less than the last element added to the run the element's sort value is increased so it will be part of the next run. On average, a run will be 100% longer than the capacity of the priority queue. Tournament sorts may be used in N-way merges.

The name comes from its similarity to a single-elimination tournament where there are many players that play in two-sided matches. Each match compares the players, the winning player is promoted to play at match at the next level up; the hierarchy continues. The tournament determines the best player, but the player, beaten in the final match may not be the second best – he may be inferior to other players the winner bested; the following is an implementation of tournament sort in Haskell, based on Scheme code by Stepanov and Kershenbaum.
