Empirical Variational Mode Decomposition Based on Binary Tree Algorithm [PDF]

open access: yesSensors, 2022
Aiming at non-stationary signals with complex components, the performance of a variational mode decomposition (VMD) algorithm is seriously affected by the key parameters such as the number of modes K, the quadratic penalty parameter α and the update step

Binary tree-inspired digital dendrimer [PDF]

open access: yesNature Communications, 2019
Digital polymers with precisely ordered units for next-generation data storage media are continually investigated for higher storage capacity. Here the authors show the synthesis of information-coded 2D digital dendrimers and the generated data matrix ...

On the complexity of non-binary tree reconciliation with endosymbiotic gene transfer [PDF]

open access: yesAlgorithms for Molecular Biology, 2023
Reconciling a non-binary gene tree with a binary species tree can be done efficiently in the absence of horizontal gene transfers, but becomes NP-hard in the presence of gene transfers.

Weighted full binary tree-sliced binary pattern: An RGB-D image descriptor [PDF]

open access: yesHeliyon, 2020
We present an Algorithm to understand Inter-pixel similarity, which shall be observed in images with the help of a data structure Full Binary Tree. The Full Binary Tree has certain properties like every node must have 2 children or none.

Generation of Binary Tree-Child phylogenetic networks. [PDF]

open access: yesPLoS Computational Biology, 2019
Phylogenetic networks generalize phylogenetic trees by allowing the modelization of events of reticulate evolution. Among the different kinds of phylogenetic networks that have been proposed in the literature, the subclass of binary tree-child networks ...

An algorithm of image mosaic based on binary tree and eliminating distortion error. [PDF]

open access: yesPLoS ONE, 2019
The traditional image mosaic result based on SIFT feature points extraction, to some extent, has distortion errors: the larger the input image set, the greater the spliced panoramic distortion.

Models for Generation of Proof Forest in zk-SNARK Based Sidechains

open access: yesCryptography, 2023
Sidechains are among the most promising scalability and extended functionality solutions for blockchains. Application of zero knowledge techniques (Latus, Mina) allows for reaching high level security and general throughput, though it brings new ...

Embedding phylogenetic trees in networks of low treewidth [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
Given a rooted, binary phylogenetic network and a rooted, binary phylogenetic tree, can the tree be embedded into the network? This problem, called \textsc{Tree Containment}, arises when validating networks constructed by phylogenetic inference methods ...
