Benefits, costs and reactivity of inducible defences: an experimental test with rotifers
Aranguiz-Acuna, A - Ramos-Jiliberto, R - Sarma, N - Sarma, SSS - Bustamante, RO - Toledo, V

Formato:	Article
Enlaces:	P>1. A key aspect of the ecology and evolution of adaptive prey responses to predator risk is the timing by which the former develop a defensive trait in response to inducing signals released by the latter. This property, called reactivity,…

Flow of linear molecules through a 4:1:4 contraction-expansion using non-equilibrium molecular dynamics: Extensional rheology and pressure drop
Castillo-Tejas, J - Rojas-Morales, A - Alvarado, JFJ - Luna-Barcenas, G - Bautista, F - Manero, O - López-Medina, F

Formato:	Article
Enlaces:	In this work, non-equilibrium molecular dynamics simulations are used to generate the flow of linear polymer chains (monomer-springs with FENE potential) and a Lennard-Jones fluid (Newtonian fluid) through a con traction-expansion (4:1:4) geometry. An external force field simulating a constant…

Impact of Transcription Units rearrangement on the evolution of the regulatory network of gamma-proteobacteria
Perez, ADG - Angarica, VE - Vasconcelos, ATR - Collado-Vides, J - González, EG

Formato:	Article
Enlaces:	Background: In the past years, several studies begun to unravel the structure, dynamical properties, and evolution of transcriptional regulatory networks. However, even those comparative studies that focus on a group of closely related organisms are limited by the rather scarce…

Modeling Information Equality: Social and Media Latency Effects on Information Diffusion
Sinnreich, Aram - Chib, Arul - Gilbert, Jesse

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion,
Enlaces:	In this study, we build and test a stochastic, agent-based model of information diffusion, called dFusion. The model incorporates diffusion research and social network analysis into a framework that is consistent with the findings of digital divide and knowledge gap…
