The Weights and Measures Commission would, in 1799, adopt a flattening of based on analysis by Pierre-Simon Laplace who combined the arc of Peru and the data of the meridian arc of Delambre and Méchain. [35] Combining these two data sets Laplace succeeded to estimate the flattening anew and was happy to find the suitable value 1 / 334 .

A metric tree is any tree data structure specialized to index data in metric spaces. Metric trees exploit properties of metric spaces such as the triangle inequality to make accesses to the data more efficient. Examples include the M-tree, vp-trees, cover trees, MVP trees, and BK-trees. [1]
An alignment-free bioinformatics procedure to infer distance-based phylogenetic trees from genome assemblies, specifically designed to quickly infer trees from genomes belonging to the same genus: MinHash-based pairwise genome distance, Balanced Minimum Evolution (BME), ratchet-based BME tree search, Rate of Elementary Quartets: A. Criscuolo ...

The metre (or meter in US spelling; symbol: m) is the base unit of length in the International System of Units (SI). Since 2019, the metre has been defined as the length of the path travelled by light in vacuum during a time interval of 1 / 299 792 458 of a second, where the second is defined by a hyperfine transition frequency of caesium.
Phylogenetic comparative methods (PCMs) use information on the historical relationships of lineages (phylogenies) to test evolutionary hypotheses.The comparative method has a long history in evolutionary biology; indeed, Charles Darwin used differences and similarities between species as a major source of evidence in The Origin of Species.
Subtrees can also be displayed in its own tree explorer with all the same features and options. [38] The compute menu provides options for computing a condensed tree, a consensus tree, or a timetree with or without a molecular clock. [39] The file menu provides options for saving, exporting, printing, and exiting.
