LUCY is an open-source structure elucidation method based on the HMBC data of unknown molecules, [16] and involves an exhaustive 2-step structure generation process where first all combinations of interpretations of HMBC signals are implemented in a connectivity matrix, which is then completed by a deterministic generator filling in missing ...
Data cells should normally have plain unbolded text, and a lighter background. In the table below the data cell wikitext is on the same line as the row header wikitext. This causes the data cell backgrounds to be the same shade of gray as the column and row headers. It also makes the data cell text bold. See how to fix this after the table.
A small phone book as a hash table. In computer science, a hash table is a data structure that implements an associative array, also called a dictionary or simply map; an associative array is an abstract data type that maps keys to values. [3]
That is, they can tell whether a given word representation of a group element is in a "canonical form" and can tell whether two elements given in canonical words differ by a generator. [1] More precisely, let G be a group and A be a finite set of generators. Then an automatic structure of G with respect to A is a set of finite-state automata: [2]
The irreducible complex characters of a finite group form a character table which encodes much useful information about the group G in a concise form. Each row is labelled by an irreducible character and the entries in the row are the values of that character on any representative of the respective conjugacy class of G (because characters are class functions).
They also introduced ISIS/Base, a chemical database program suited to the storage of relatively small numbers of structures with associated data for personal use independently of corporate systems. ISIS/Draw structures could be incorporated into other documents, for example using the word processor software which was becoming available in the ...
The zipper technique is general in the sense that it can be adapted to lists, trees, and other recursively defined data structures. Such modified data structures are usually referred to as "a tree with zipper" or "a list with zipper" to emphasize that the structure is conceptually a tree or list, while the zipper is a detail of the implementation.
Diagram illustrating compaction of data in a log-structured merge tree. Most LSM trees used in practice employ multiple levels. Level 0 is kept in main memory, and might be represented using a tree. The on-disk data is organized into sorted runs of data. Each run contains data sorted by the index key.
