Radial Domany-Kinzel Models with Mutation and Selection [PDF]
Phys. Rev. E 87, 012103 (2013), 2012 We study the effect of spatial structure, genetic drift, mutation, and selective pressure on the evolutionary dynamics in a simplified model of asexual organisms colonizing a new territory. Under an appropriate coarse-graining, the evolutionary dynamics is related to the directed percolation processes that arise in voter models, the Domany-Kinzel (DK ...

Advanced Functional Materials, EarlyView.A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Genetic drift at expanding frontiers promotes gene segregation
, 2007 Competition between random genetic drift and natural selection plays a central role in evolution: Whereas non-beneficial mutations often prevail in small populations by chance, mutations that sweep through large populations typically confer a selective ...

Biocompatibility and antibacterial properties of zirconium nitride coating on titanium abutments: An in vitro study [PDF]
, 2018 Improving soft tissue attachment and reducing bacterial colonization on titanium abutments are key factors for the long-term maintenance of healthy soft and hard peri-implant tissues.

Advanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.The challenges of studying inflammatory bowel disease (IBD), highlighting limitations of traditional 2D cell cultures and animal models are discussed here. It introduces human intestine organ‐on‐chip (OoC) models as a promising alternative, capable of more accurately mimicking the intestinal microenvironment.

Legal origin, colonial origin and deforestation [PDF]
This paper investigates whether inherited legacies such as legal origin allow of explaining deforestation in 110 developed and developing countries. The hypothesis is that differences in deforestation between countries can be attributed to their legal ...

Colonization and collapse on Homogeneous Trees [PDF]
arXiv, 2016 We investigate a basic immigration process where colonies grow, during a random time, according to a general counting process until collapse. Upon collapse a random amount of individuals survive. These survivors try independently establishing new colonies at neighbour sites.

An Exploration of Mars Colonization with Agent-Based Modeling [PDF]
arXiv, 2023 Establishing a human settlement on Mars is an incredibly complex engineering problem. The inhospitable nature of the Martian environment requires any habitat to be largely self-sustaining. Beyond mining a few basic minerals and water, the colonizers will be dependent on Earth resupply and replenishment of necessities via technological means, i.e ...

Spatial scales of interactions among bacteria and between bacteria and the leaf surface. [PDF]
, 2015 Microbial life on plant leaves is characterized by a multitude of interactions between leaf colonizers and their environment. While the existence of many of these interactions has been confirmed, their spatial scale or reach often remained unknown.

Probiotic‐Based Mineralized Living Materials to Produce Antimicrobial Yogurts
Advanced Healthcare Materials, Volume 14, Issue 12, May 6, 2025.The self‐assembly and mineralization of collagen in the presence of probiotics produces hybrid living materials that hosts and protects the cells. Intra‐ and interfibrillar mineralization of collagen fibers, as occurring in bone, results, respectively, in a bulk and single‐cell protective layer of cells, that survive in simulated gastric conditions and,
