Parsimony and Model-Based Analyses of Indels in Avian Nuclear Genes Reveal Congruent and Incongruent Phylogenetic Signals

Biology, 2013
Insertion/deletion (indel) mutations, which are represented by gaps in multiple sequence alignments, have been used to examine phylogenetic hypotheses for some time.

Unlocking the potential of secure communications: A comprehensive systematic review of the network design model for topology control and routing synergy in wireless sensor networks for prolonged longevity

Results in Engineering
This research focuses on the unified topology governance and connectivity challenge in wireless sensor networks (WSNs). We use a multilayered topology and transportation architecture containing numerous sources and develop a topology control mechanism ...

Strongly Coloured Thiocyanate Frameworks with Perovskite-Analogue Structures [PDF]

, 2018
We report the first examples of thiocyanate-based analogues of the cyanide Prussian blue compounds, MIII[Bi(SCN)6], M= Fe, Cr, Sc. These compounds adopt the primitive cubic pcu topology and show strict cation order.

Continuous Order-Preserving Functions for All Kind of Preorders

, 2023
A topology is said to be strongly useful if every weakly continuous preorder admits a continuous order-preserving function. A strongly useful topology is useful, in the sense that every continuous total preorder admits a continuous utility representation.

Inferring interactions in multispecies communities: The cryptocurrency market case.

PLoS ONE, 2023
We introduce a general framework for empirically detecting interactions in communities of entities characterized by different features. This approach is inspired by ideas and methods coming from ecology and finance and is applied to a large dataset ...

The importance of ambient sound level to characterise anuran habitat. [PDF]

PLoS ONE, 2013
Habitat characterisation is a pivotal step of any animal ecology study. The choice of variables used to describe habitats is crucial and need to be relevant to the ecology and behaviour of the species, in order to reflect biologically meaningful ...

Complete plastid genome sequencing of Trochodendraceae reveals a significant expansion of the inverted repeat and suggests a Paleogene divergence between the two extant species. [PDF]

PLoS ONE, 2013
The early-diverging eudicot order Trochodendrales contains only two monospecific genera, Tetracentron and Trochodendron. Although an extensive fossil record indicates that the clade is perhaps 100 million years old and was widespread throughout the ...

Periodic Reordering [PDF]

, 1988
For many networks in nature, science and technology, it is possible to order the nodes so that most links are short-range, connecting near-neighbours, and relatively few long-range links, or shortcuts, are present.

A phylogenomic study of Steganinae fruit flies (Diptera: Drosophilidae): strong gene tree heterogeneity and evidence for monophyly

BMC Evolutionary Biology, 2020
Background The Drosophilidae family is traditionally divided into two subfamilies: Drosophilinae and Steganinae. This division is based on morphological characters, and the two subfamilies have been treated as monophyletic in most of the literature, but ...

Topology and control strategy for accelerated lifetime test setup of DC-link capacitor of wind turbine converter [PDF]

, 2016
Back-to-back converters for wind turbine systems (WTS) feature capacitors in the DC-link to maintain a stable DC-link voltage and to decouple the generator from the grid. Electrolytic and film capacitors can be chosen to this purpose.
