A Continuous-Time and State-Space Relaxation of the Linear Threshold Model with Nonlinear Opinion Dynamics
Ian Xul Belaustegui, Himani Sinhmar, Ling-Wei Kong +2
The Linear Threshold Model (LTM) is widely used to study the propagation of collective behaviors as complex contagions. However, its dependence on discrete states and timesteps res…
Bacteria push the limits of chemotactic precision to navigate dynamic chemical gradients
Douglas R. Brumley, Francesco Carrara, Andrew M. Hein +3
Ephemeral aggregations of bacteria are ubiquitous in the environment, where they serve as hotbeds of metabolic activity, nutrient cycling, and horizontal gene transfer. In many cas…
Physical Limits on Bacterial Navigation in Dynamic Environments
Andrew M. Hein, Douglas R. Brumley, Francesco Carrara +2
Many chemotactic bacteria inhabit environments in which chemicals appear as localized pulses and evolve by processes such as diffusion and mixing. We show that, in such environment…
Sensing and decision-making in random search
Andrew M. Hein, Scott A. McKinley
While microscopic organisms can use gradient-based search to locate resources, this strategy can be poorly suited to the sensory signals available to macroscopic organisms. We prop…
