Rope (data structure)

In computer programming, a rope, or cord, is a data structure composed of smaller strings that is used for efficiently storing and manipulating a very long string. For example, a text editing program may use a rope to represent the text being edited, so that operations such as insertion, deletion, and random access can be done efficiently.

Description

A rope is a binary tree having leaf nodes that contain a short string. Each node has a weight value equal to the length of its string plus the sum of all leaf nodes' weight in its left subtree, namely the weight of a node is the total string length in its left subtree for a non-leaf node, or the string length of itself for a leaf node. Thus a node with two children divides the whole string into two parts: the left subtree stores the first part of the string. The right subtree stores the second part and its weight is the sum of the left child's weight and the length of its contained string.

The binary tree can be seen as several levels of nodes. The bottom level contains all the nodes that contain a string. Higher levels have fewer and fewer nodes. The top level consists of a single "root" node. The rope is built by putting the nodes with short strings in the bottom level, then attaching a random half of the nodes to parent nodes in the next level.

Rope (play)

Rope is a 1929 British play by Patrick Hamilton. In formal terms, it is a well-made play with a three-act dramatic structure that adheres to the classical unities. Its action is continuous, punctuated only by the curtain fall at the end of each act. It may also be considered a thriller whose gruesome subject matter invites comparison to the Grand Guignol style of theatre. Samuel French published the play in 1929.

Plot and setting

The play is set on the first floor of a house in Mayfair, London in 1929. The story, thought to be based loosely on the Leopold and Loeb murder case, concerns two young university students, Wyndham Brandon and Charles Granillo (whom Brandon calls "Granno"), who have murdered fellow student Ronald Kentley as an expression of their supposed intellectual superiority. At the beginning of the play they hide Kentley's body in a chest. They proceed to host a party for his friends and family at which the chest containing his corpse is used to serve a buffet.

Thematic vowel

In Indo-European studies, a thematic vowel or theme vowel is the vowel *e or *o from ablaut placed before the ending of a Proto-Indo-European (PIE) word. Nouns, adjectives, and verbs in the Indo-European languages with this vowel are thematic, and those without it are athematic. Used more generally, a thematic vowel is any vowel found at the end of the stem of a word.

Proto-Indo-European

PIE verbs and nominals (nouns and adjectives) consist of three parts:

The thematic vowel, if present, occurs at the end of the suffix (which may include other vowels or consonants) and before the ending:

Athematic forms, by contrast, have a suffix ending in a consonant, or no suffix at all (or arguably a null suffix):

For several reasons, athematic forms are thought to be older, and the thematic vowel was likely an innovation of late PIE: Athematic paradigms (inflection patterns) are more "irregular", exhibiting ablaut and mobile accent, while the thematic paradigms can be seen as a simplification or regularisation of verbal and nominal grammar. In the Anatolian languages, which were the earliest to split from PIE, thematic verbs are rare or absent. Furthermore, during late PIE and in the older daughter languages, a number of athematic forms were replaced by thematic ones, as in prehistoric Greek *thes- 'god' versus *thes-o- > Classical Greek θεός (theós).

The Family Way (soundtrack)

The Family Way is a soundtrack recording composed by Paul McCartney, released in January 1967. The album is the soundtrack to the 1966 film of the same name, directed by Roy Boulting and starring Hayley Mills. Produced and arranged by George Martin, the album was credited to "The George Martin Orchestra" and issued under the full title The Family Way (Original Soundtrack Album). A 45rpm single, again credited to the George Martin Orchestra, was issued on 23 December 1966, comprising "Love in the Open Air" backed with "Theme From 'The Family Way'", as United Artists UP1165.

The Family Way won an Ivor Novello Award in 1967. It was remastered and released on CD in 1996 with new musical compositions not on the original 1967 soundtrack album.

The recording took place over November and December 1966, before the Beatles began work on their album Sgt. Pepper's Lonely Hearts Club Band. McCartney's involvement in the project was minimal, according to biographer Howard Sounes, who quotes Martin's recollection that he had to "pester Paul for the briefest scrap of a tune" with which to start writing the score. After McCartney had provided "a sweet little fragment of a waltz tune", Martin continued, "I was able to complete the score."
