The Signaling Petri Net-Based Simulator: A Non-Parametric Strategy for Characterizing the Dynamics of Cell-Specific Signaling Networks [PDF]

, 2008
Reconstructing cellular signaling networks and understanding how they work are major endeavors in cell biology. The scale and complexity of these networks, however, render their analysis using experimental biology approaches alone very challenging.

Body size evolution as a catalyst for diversification of copulation strategies and its spillover effects on genital evolution and phylogenetic divergence in terrestrial arthropods

Population Ecology, EarlyView.
A scenario in which divergent selection derived from ecological environments leads to genital divergence through body size evolution. Abstract To explore how ecological diversity contributes to the establishment of ecologically similar species with sexual divergence, this review focuses on body size—an environmentally influenced trait that determines ...

Heterogeneous anomalous transport in cellular and molecular biology [PDF]

arXiv, 2023
It is well established that a wide variety of phenomena in cellular and molecular biology involve anomalous transport e.g. the statistics for the motility of cells and molecules are fractional and do not conform to the archetypes of simple diffusion or ballistic transport.

Population and species neighbor identity impact trait–trait relationships and plant performance

Population Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...

Direct capture and sequencing reveal ultra-short single-stranded DNA in biofluids

iScience, 2022
Summary: Cell-free DNA (cfDNA) has become the predominant analyte of liquid biopsy; however, recent studies suggest the presence of subnucleosomal-sized DNA fragments in circulation that are likely single-stranded.
