IQ-TREE 2: New Models and Efficient Methods for Phylogenetic Inference in the Genomic Era

open access: yesbioRxiv, 2019
IQ-TREE (http://www.iqtree.org) is a user-friendly and widely used software package for phylogenetic inference using maximum likelihood. Since the release of version 1 in 2014, we have continuously expanded IQ-TREE to integrate a plethora of new models ...

On the Distance Spectral Radius of Trees with Given Degree Sequence

open access: yesDiscussiones Mathematicae Graph Theory, 2020
We consider the problem of maximizing the distance spectral radius and a slight generalization thereof among all trees with some prescribed degree sequence.

Trees with Distinguishing Index Equal Distinguishing Number Plus One

open access: yesDiscussiones Mathematicae Graph Theory, 2020
The distinguishing number (index) D(G) (D′ (G)) of a graph G is the least integer d such that G has an vertex (edge) labeling with d labels that is preserved only by the trivial automorphism.

Improved Semantic Representations From Tree-Structured Long Short-Term Memory Networks [PDF]

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2015
Because of their superior ability to preserve sequence information over time, Long Short-Term Memory (LSTM) networks, a type of recurrent neural network with a more complex computational unit, have obtained strong results on a variety of sequence ...

Zaštita životne sredine u građevinarstvu sa osvrtom na primenu ekoloških i nano materijala / Environmental protection in civil engineering with regard to the use of eco and nano materials / Защита окружающей среды в строительстве при использовании экологичных и наноматериалов

open access: yesVojnotehnički Glasnik, 2015
Antropogeni i tehnogeni uticaj na životnu sredinu pojačan je u poslednjoj deceniji XX veka. Taj trend se nastavlja i u XXI veku, a ofanziva globalizacije donosi nove ekološke probleme. Globalni ekološki problemi najviše pogađaju gradove.

Matching-Type Image-Labelings of Trees

open access: yesMathematics, 2021
A variety of labelings on trees have emerged in order to attack the Graceful Tree Conjecture, but lack showing the connections between two labelings. In this paper, we propose two new labelings: vertex image-labeling and edge image-labeling, and combine ...

Tree compression with top trees [PDF]

open access: yesInformation and Computation, 2013
We introduce a new compression scheme for labeled trees based on top trees. Our compression scheme is the first to simultaneously take advantage of internal repeats in the tree (as opposed to the classical DAG compression that only exploits rooted subtree repeats) while also supporting fast navigational queries directly on the compressed representation.

Hash Trees Versus B-Trees [PDF]

open access: yesThe Computer Journal, 1984
Summary: The hash trees method of external hashing is known to have advantages for certain types of primary key distribution. In this paper the value of the method as a general indexing technique - for secondary keys as well as primary keys - is assessed, and comparison with the B-trees method is presented.
