q-bio.PE · 101 papersUniversal statistical signatures of evolution in artificial intelligence architectures
AI architectural evolution exhibits statistical signatures akin to biological evolution, with heavy-tailed fitness effects and convergent traits.
Fragmentation is a diversity ratchet
Landscape fragmentation acts as a "diversity ratchet," increasing biodiversity by reducing interspecies connectivity and preventing extinctions.
Scale-dependent Temporal Signatures of Arboviral Transmission in Urban Environments
A new spatiotemporal model reveals that arboviral epidemic differentiation in urban areas is scale-dependent, primarily driven by temporal dynamics, not spatial proximity.
An Improved Bipartition Cover Bound for the Multispecies Coalescent Model
This paper presents improved topology-free upper bounds on the number of loci needed for bipartition cover in the multispecies coalescent model.
Analysis of non pharmaceutical interventions with SIR epidemic models: decreasing the infection peak vs. minimizing the epidemic size
This study uses SIR models to show that minimizing epidemic peaks requires earlier non-pharmaceutical interventions than minimizing overall epidemic size.
Temporal Structure Mediates the Robustness and Collapse of Plant-Pollinator Networks
Temporal dynamics shape plant-pollinator network robustness, causing shifts between diverse and collapsed community states.
Generation time in a discrete epidemic model with asymptomatic carriers: beyond geometric waiting times
This paper models generation time in discrete epidemics with asymptomatic carriers, using non-Markovian waiting times and variable infectiousness.
Emergence of cooperation in nonlinear higher-order public goods games
This paper explores cooperation in nonlinear public goods games on hypergraphs, showing how network structure and game type influence outcomes.
WebCVTree4: A Newly Designed Phylogenetic and Taxonomic Study Platform for Prokaryotes Using Composition Vectors and Whole Genomes
WebCVTree4 is an upgraded web platform for prokaryotic phylogenetic and taxonomic studies using whole-genome composition vectors, supporting large-scale analysis.
Mathematical Models of Evolution and Replicator Systems Dynamics. Chapter 1: Introduction to Replicator Systems
This chapter introduces mathematical models of replicator systems, deriving the replicator equation and surveying quasispecies theory for generalized evolutionary dynamics.
A graph based advection framework for climate-driven species distribution
This paper introduces a graph-based advection framework to model climate-driven species distribution, incorporating directed movement and its impact on persistence and hotspots.
A mathematical theory of evolution for self-designing AIs
This paper models self-designing AI evolution, showing how directed design and human fitness functions shape traits, with key implications for alignment.
Nested tree space: a geometric framework for co-phylogeny
Introduces σ-space, a CAT(0) geometric framework for nested phylogenetic trees, enabling analysis of co-evolutionary systems.
Partial health status observability and time horizon uncertainty in mean-field game epidemiological models
MFG epidemiological models are introduced to handle partial immunity observability and time horizon uncertainty using efficient ODE approximations.
Overcoming unfairness via repeated interactions in mini-ultimatum game
This paper models how repeated interactions in a mini-ultimatum game promote fairness, showing specific strategies maintain it against unfairness.
Synonymous Codon Usage Bias Overrides Phylogeny to Reflect Convergent Frond Architecture in a Rapidly Radiating Fern Family Thelypteridaceae
Ferns show that synonymous codon usage bias (CUB) can override phylogeny, reflecting convergent frond architecture driven by specific photosynthesis genes.
Competition at the front of expanding populations
This paper introduces a model combining Fisher and KPZ equations to show how spatial expansion can overcome reproductive advantage in species competition.
The fitness landscape of overlapping genes
This paper explores the fitness landscape of overlapping genes, revealing compatibility, trade-offs, and the natural genetic code's unique suitability.
How to Forage for a Mate?
This paper models mate choice as an optimal foraging problem, revealing how decision thresholds for leaving or committing to a mate are influenced by signal availability.
Macroscopic Signatures of Gauge-Mediated Contagion: Deriving Behavioral Shielding from Stochastic Field Theory
This paper uses stochastic field theory to model epidemics, showing how behavioral shielding emerges from gauge-mediated contagion and dynamically suppresses R_eff.
