Effect of environmental variation on the benefits of learning
Xiao Zhou, BingKan Xue
Signal recognition plays a critical role in species interactions and can be enhanced by learning signal characteristics through experience. In brood parasitism, host species may us…
Modeling and Inferring Metacommunity Dynamics with Maximum Caliber
Zachary Jackson, Mathew A. Leibold, Robert D. Holt +1
A major challenge for community ecology is using spatio-temporal data to infer parameters of dynamical models without conducting laborious experiments. We present a novel framework…
Dynamic trait distribution as a source for shifts in interaction strength and population density
Zachary Jackson, BingKan Xue
Intraspecific trait variation has been increasingly recognized as an important factor in determining species interaction and diversity. Eco-evolutionary models have studied the dis…
The value of internal memory for population growth in varying environments
Leo Law, BingKan Xue
In varying environments it is beneficial for organisms to utilize available cues to infer the conditions they may encounter and express potentially favorable traits. However, exter…
Robust retrieval of dynamic sequences through interaction modulation
Lukas Herron, Pablo Sartori, BingKan Xue
Many biological systems dynamically rearrange their components through a sequence of configurations in order to perform their functions. Such dynamic processes have been studied us…
Heterogeneity of Interaction Strengths and Its Consequences on Ecological Systems
Zachary Jackson, BingKan Xue
Ecosystems are formed by networks of species and their interactions. Traditional models of such interactions assume a constant interaction strength between a given pair of species.…
Effect of compositional fluctuation on the survival of bet-hedging species
Xiao Zhou, BingKan Xue
Understanding the coexistence of diverse species in a changing environment is an important problem in community ecology. Bet-hedging is a strategy that helps species survive in suc…
Geometry of environment-to-phenotype mapping: Unifying adaptation strategies in varying environments
BingKan Xue, Pablo Sartori, Stanislas Leibler
Biological organisms exhibit diverse strategies for adapting to varying environments. For example, a population of organisms may express the same phenotype in all environments (`un…
Regularization of the big bang singularity with random perturbations
Edward Belbruno, BingKan Xue
We show how to regularize the big bang singularity in the presence of random perturbations modeled by Brownian motion using stochastic methods. We prove that the physical variables…
Bet-hedging against demographic fluctuations
BingKan Xue, Stanislas Leibler
Biological organisms have to cope with stochastic variations in both the external environment and the internal population dynamics. Theoretical studies and laboratory experiments s…
Regularization of the big bang singularity with a time varying equation of state
BingKan Xue, Edward Belbruno
We study the classical dynamics of the universe undergoing a transition from contraction to expansion through a big bang singularity. The dynamics is described by a system of diffe…
Nonperturbative analysis of the evolution of cosmological perturbations through a nonsingular bounce
BingKan Xue, David Garfinkle, Frans Pretorius +1
In bouncing cosmology, the primordial fluctuations are generated in a cosmic contraction phase before the bounce into the current expansion phase. For a nonsingular bounce, curvatu…
The four fixed points of scale invariant single field cosmological models
BingKan Xue
We introduce a new set of flow parameters to describe the time dependence of the equation of state and the speed of sound in single field cosmological models. A scale invariant pow…
Evolution of curvature and anisotropy near a nonsingular bounce
BingKan Xue, Paul J. Steinhardt
We consider bouncing cosmologies in which an ekpyrotic contraction phase with w >> 1 is followed by a bouncing phase with w < -1 that violates the null energy condition. The bounci…
Unstable growth of curvature perturbation in non-singular bouncing cosmologies
BingKan Xue, Paul J. Steinhardt
We consider non-singular bouncing cosmologies, such as the new ekpyrotic model, in which the universe undergoes a slow contraction phase with equation of state , followed…
