In computing, data deduplication is a technique for eliminating duplicate copies of repeating data. Successful implementation of the technique can improve storage utilization, which may in turn lower capital expenditure by reducing the overall amount of storage media required to meet storage capacity needs.
Reduplicative paramnesia is the delusional belief that a place or location has been duplicated, existing in two or more places simultaneously, or that it has been 'relocated' to another site.
A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row in a database table every time said table is accessed.
Most pages in this structure will be leaf pages which refer to specific table rows. Because each node (or internal page) can have more than two children, a B-tree index will usually have a shorter height (the distance from the root to the farthest leaf) than a Binary Search Tree.
The more copies of the same (duplicated) gene a cell has in its genome, the more gene product can be produced simultaneously. Assuming that no regulatory feedback loops exist that automatically down-regulate gene expression, the amount of gene product (or gene dosage) will increase with each additional gene copy, until some upper limit is ...
Pingelapese is a Micronesian language spoken on the Pingelap atoll and on two of the eastern Caroline Islands, called the high island of Pohnpei. Pingelapese utilizes both duplication and triplication of a verb or part of a verb to express that something is happening for certain duration of time. No reduplication means that something happens.
The Virgo interferometer is a large-scale scientific instrument near Pisa, Italy, for detecting gravitational waves.The detector measures minuscule length variations in its two 3-kilometre (1.9-mile) arms induced by the passage of gravitational waves.
In algebraic terms, doubling a unit cube requires the construction of a line segment of length x, where x 3 = 2; in other words, x = , the cube root of two. This is because a cube of side length 1 has a volume of 1 3 = 1 , and a cube of twice that volume (a volume of 2) has a side length of the cube root of 2.
