1 dzień temu · The first line of a phylip-formatted distance matrix contains the number of sequences; the following lines have the sequence name with the pairwise distance compared to the other sequences. Next, the distance matrix was converted to MEGA format with an in-house R-script and used to construct a Neighbor-Joining tree with the MEGA (v11.0.13 ...
5 dni temu · We present the first combinatorial proof of the Graham-Pollak Formula for the determinant of the distance matrix of a tree, via sign-reversing involutions and the Lindström-Gessel-Viennot Lemma.
5 dni temu · The extent to which our machine-learnt embedding distances, based on image similarity, were correlated with independent evolutionary phylogenetic information was quantitatively validated 35 ...
4 dni temu · Classification of gene trees is an important task both in the analysis of multi-locus phylogenetic data, and assessment of the convergence of Markov Chain Monte Carlo (MCMC) analyses used in Bayesian phylogenetic tree reconstruction. The logistic regression model is one of the most popular classification models in statistical learning, thanks to its computational speed and interpretability ...
4 dni temu · Abstract: Let $T = ([n], E)$ be a tree and let $D = ( d(i,j) )_{i, j \le n}$ be the distance matrix of $T$. Let $S\subseteq [n]$. We give the first combinatorial proof for a formula to compute the principal minor of $D$ indexed by $S$, namely $\det D[S]$.
17 godz. temu · Background Engelhardia (Juglandaceae) is a genus of significant ecological and economic importance, prevalent in the tropics and subtropics of East Asia. Although previous efforts based on multiple molecular markers providing profound insights into species delimitation and phylogeography of Engelhardia, the maternal genome evolution and phylogeny of Engelhardia in Juglandaceae still need to be ...
4 dni temu · Fig. 1. Phylogenetic survival analysis workflow. The proposed approach starts with a genome alignment as input, from which a phylogenetic tree is inferred. Different phenotypes are then determined for each isolate at the tips of the tree. For representation, the phenotype of interest is characterized by red color.
