Competitive advantages of T-even phage lysis inhibition in response to secondary infection

This study uses a mathematical model to analyze how lysis inhibition in T-even phages provides competitive advantages in different environments.

Emergent collective alignment gives competitive advantage to longer cells during range expansion

The paper shows longer bacterial cells gain a competitive advantage during range expansion through collective alignment, blocking shorter cells from resources.

Genetic mixing and demixing on expanding spherical frontiers

This study examines genetic mixing and demixing in 3D bacterial range expansions, showing sector formation and merging dynamics consistent with a modified 3D Eden growth model.

The dynamics of phage predation on a microcolony

The paper experimentally quantifies phage predation on E. coli microcolonies and uses a model to show that T4 phage can penetrate deep enough to threaten colony survival despite shielding.

Motility mediates satellite formation in confined biofilms

The paper shows how satellite colonies form around biofilms in semi-soft agar, demonstrating that motility and matrix elasticity enable faster bacterial expansion while maintaining community interactions.

Existence of log-phase Escherichia coli persisters and lasting memory of a starvation pulse

This study quantifies long-term killing dynamics of E. coli during antibiotic treatment and identifies a memory effect from carbon starvation.

Distinct survival, growth lag, and ribosomal RNA degradation kinetics during long-term starvation for carbon or phosphate

This study compares ribosomal RNA degradation and survival kinetics in Escherichia coli under carbon and phosphate starvation, finding faster rRNA loss and longer lag times under phosphate starvation.

On phage adsorption to bacterial chains

The paper investigates how bacterial spatial arrangements affect phage adsorption rates and shows that clustered structures significantly reduce adsorption and increase superinfection rates.

How pirate phage interferes with helper phage: Comparison of the two distinct strategies

The paper compares two strategies of pirate phage interference with helper phages using mathematical models, finding SaPIs more effectively interfere with helper phage spreading than P4 in well-mixed environments.

Sustainability of spatially distributed bacteria-phage systems

The paper models spatially distributed bacteria-phage systems to show that spatial separation and colony growth protect bacteria from phage-driven extinction.

A Growing Microcolony can Survive and Support Persistent Propagation of Virulent Phages

The paper shows that larger bacterial colonies can survive virulent phages by outgrowing surface infections, with a critical size threshold identified through mathematical modeling.

Existence and construction of large stable food webs

This paper constructs large stable food webs using classical Lotka-Volterra equations by sequentially adding species and demonstrating stability through weak interactions.
