Speed-quality tradeoff in a physical model of molecular sorting
Elisa Floris, Damiano Andreghetti, Thibaut Caplet +2
Eukaryotic cells rely on membrane-mediated processes to compartmentalize biomolecules, counteracting diffusion-driven homogenization. These processes involve the selective sorting…
Sparse Interactions Reshape Stability in Random Lotka-Volterra Dynamics
Mattia Tarabolo, Luca Dall'Asta, Roberto Mulet
Classical approaches to ecological stability rely on fully connected interaction models, yet real ecosystems are sparse and structured--a feature that qualitatively reshapes their…
Enzyme-driven phase separation
Damiano Andreghetti, Alfredo Braunstein, Luca Dall'Asta +1
The formation of polarized signaling domains on cell membranes is a fundamental example of biological pattern formation. While such patterns resemble structures from equilibrium ph…
Molecular sorting on a fluctuating membrane
Damiano Andreghetti, Luca Dall'Asta, Andrea Gamba +2
Molecular sorting in biological membranes is essential for proper cellular function. It also plays a crucial role in the budding of enveloped viruses from host cells. We recently p…
Gaussian approximation of dynamic cavity equations for linearly-coupled stochastic dynamics
Mattia Tarabolo, Luca Dall'Asta
Stochastic dynamics on sparse graphs and disordered systems often lead to complex behaviors characterized by heterogeneity in time and spatial scales, slow relaxation, localization…
