Alignment-free phylogenetic reconstruction: Sample complexity via a branching process analysis [PDF]
, 2012 We present an efficient phylogenetic reconstruction algorithm allowing insertions and deletions which provably achieves a sequence-length requirement (or sample complexity) growing polynomially in the number of taxa. Our algorithm is distance-based, that

Advanced Biology, EarlyView.The relationship between proteome size, amino acid composition, and lifespan across 276 vertebrate species is investigated. Proteome size correlates positively with lifespan in mammals but negatively in birds and fish. While proteome composition varies among classes, no single amino acid frequency correlates with lifespan.

Stability analysis of phylogenetic trees [PDF]
Bioinformatics, 2012 Abstract Motivation: Phylogenetics, or reconstructing the evolutionary relationships of organisms, is critical for understanding evolution. A large number of heuristic algorithms for phylogenetics have been developed, some of which enable estimates of trees with tens of thousands of taxa. Such trees may not be robust, as small changes in

Advanced Engineering Materials, EarlyView.Molecular dynamics simulations are advancing the study of ribonucleic acid (RNA) and RNA‐conjugated molecules. These developments include improvements in force fields, long‐timescale dynamics, and coarse‐grained models, addressing limitations and refining methods.

Natural selection and phylogenetic analysis [PDF]
Proceedings of the National Academy of Sciences, 2009 If Darwin were to survey the entirety of the biological sciences today, he would be pleased to observe how central phylogenies and “tree thinking” are to integrative research (1). Biologists of all stripes now realize that phylogenies are not exotic, but fundamental and routine tools for understanding not only history but mechanism, organization, and ...

Choreography of silk spinning by webspinners (Insecta: Embioptera) reflects lifestyle and hints at phylogeny [PDF]
, 2016 Silk spinning defines the morphologically constrained embiopterans. All individuals spin for protection, including immatures, adult males and the wingless females. Enlarged front tarsi are packed with silk glands and clothed with ejectors.

Advanced Functional Materials, EarlyView.Translation of recombinant spider silks as fillers for nerve guidance conduits in long‐segment nerve reconstruction demands a detailed examination of native counterparts. Thus, this study conducts a comprehensive analysis of the material properties of four phylogenetically diverse spider silks and their impact on Schwann cell adhesion, pinpointing key ...

Phylogenetic analysis of fungal ABC transporters
BMC Genomics, 2010 Background The superfamily of ABC proteins is among the largest known in nature. Its members are mainly, but not exclusively, involved in the transport of a broad range of substrates across biological membranes. Many contribute to multidrug resistance in

Syntactic Phylogenetic Trees [PDF]
arXiv, 2016 In this paper we identify several serious problems that arise in the use of syntactic data from the SSWL database for the purpose of computational phylogenetic reconstruction. We show that the most naive approach fails to produce reliable linguistic phylogenetic trees. We identify some of the sources of the observed problems and we discuss how they may

Evaluation of Antibiogram, Genotype and Phylogenetic Analysis of Biofield Treated Nocardia otitidis [PDF]
, 2015 Nocardiosis is a soil-borne aerobic infection caused by Nocardia species commonly affects the respiratory tract. Nocardia otitidis (N. otitidis) is the key organism for non-mycobacterial tuberculosis.
