cKd-tree: A Compact Kd-tree

open access: yesIEEE Access
In the context of Big Data scenarios, the presence of extensive static datasets is not uncommon. To facilitate efficient queries on such datasets, the utilization of multiple indexes, such as the Kd-tree, becomes imperative.

Comparing sequences without using alignments: application to HIV/SIV subtyping

open access: yesBMC Bioinformatics, 2007
Background In general, the construction of trees is based on sequence alignments. This procedure, however, leads to loss of informationwhen parts of sequence alignments (for instance ambiguous regions) are deleted before tree building.

Molecular approach for identification of Catla catla using mitochondrial CO1 from Pakistan

open access: yesMitochondrial DNA. Part B. Resources, 2020
DNA barcoding is a rapid, precise, and effective way of species identification. A short and standard target gene marker is used to create sequence profile of identified species.

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

The complete chloroplast genome sequence of precious tree, Magnolia baillonii

open access: yesMitochondrial DNA. Part B. Resources, 2019
Magnolia baillonii is an important tropical and sub-tropical precious wood tree species in China. In this study, the complete chloroplast genome (cpDNA) sequence of M. baillonii was determined from Illumina HiSeq pair-end sequencing data.

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

open access: yesAdvanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

A note on the Smarandache inversion sequence [PDF]

open access: yes, 2007
In a recent paper, Muneer introduced the Smarandache inversion sequence. In this paper, we study some properties of the Smarandache inversion sequence. Moreover, we find the necessary and su±cient condition such that [SI(n)]2 + [SI(n + 1)]2 is a perfect

Analysis framework for higher-order temporal correlations with applications to human heartbeats

open access: yesScientific Reports
We propose a time series analysis framework focused on higher-order temporal correlations in the event sequence beyond the interevent time distribution by employing the burst-tree decomposition method.
