Social contagion with degree-dependent thresholds
10.1103/PhysRevE.96.012315 2017-07-17 We investigate opinion spreading by a threshold model in a situation in which the influence of people is heterogeneously distributed. We assume that there is a coupling between the influence of an individual (measured by the out-degree) and the threshold for ... |

Multivalent ligand-receptor-mediated interaction of small filled vesicles with a cellular membrane
10.1103/PhysRevE.96.012408 2017-07-17 The ligand-receptor-mediated contacts of small sub-100-nm-sized lipid vesicles (or nanoparticles) with the cellular membrane are of interest in the contexts of cell-to-cell communication, endocytosis of membrane-coated virions, and drug (RNA) delivery. In all... |

Marginally compact fractal trees with semiflexibility
10.1103/PhysRevE.96.012501 2017-07-17 We study marginally compact macromolecular trees that are created by means of two different fractal generators. In doing so, we assume Gaussian statistics for the vectors connecting nodes of the trees. Moreover, we introduce bond-bond correlations that make t... |

Dislocation-free growth of quasicrystals from two seeds due to additional phasonic degrees of freedom
10.1103/PhysRevE.96.012602 2017-07-17 We explore the growth of two-dimensional quasicrystals, i.e., aperiodic structures that possess long-range order, from two seeds at various distances and with different orientations by using dynamical phase-field crystal calculations. We compare the results t... |

Self-assembly of rigid magnetic rods consisting of single dipolar beads in two dimensions
10.1103/PhysRevE.96.012603 2017-07-17 Molecular dynamics simulations are used to investigate the structural properties of a two-dimensional ensemble of magnetic rods, which are modeled as aligned single dipolar beads. The obtained self-assembled configurations can be characterized as (1) clusters... |

Stability of the fluid interface in a Hele-Shaw cell subjected to horizontal vibrations
10.1103/PhysRevE.96.013108 2017-07-17 The stability of the horizontal interface of two immiscible viscous fluids in a Hele-Shaw cell subject to gravity and horizontal vibrations is studied. The problem is reduced to the generalized Hill equation, which is solved analytically by the multiple scale... |

Transport and diffusion properties of Brownian particles powered by a rotating wheel
10.1103/PhysRevE.96.012131 2017-07-14 Diffusion and rectification of Brownian particles powered by a rotating wheel are numerically investigated in a two-dimensional channel. The nonequilibrium driving comes from the rotating wheel, which can break thermodynamical equilibrium and induce the direc... |

Finite-size scaling in the system of coupled oscillators with heterogeneity in coupling strength
10.1103/PhysRevE.96.012213 2017-07-14 We consider a mean-field model of coupled phase oscillators with random heterogeneity in the coupling strength. The system that we investigate here is a minimal model that contains randomness in diverse values of the coupling strength, and it is found to retu... |

Balancing specificity, sensitivity, and speed of ligand discrimination by zero-order ultraspecificity
10.1103/PhysRevE.96.012405 2017-07-14 Specific interactions between receptors and their target ligands in the presence of nontarget ligands are crucial for biological processes such as T cell ligand discrimination. To discriminate between the target and nontarget ligands, cells have to increase s... |

Optimal information transfer in enzymatic networks: A field theoretic formulation
10.1103/PhysRevE.96.012406 2017-07-14 Signaling in enzymatic networks is typically triggered by environmental fluctuations, resulting in a series of stochastic chemical reactions, leading to corruption of the signal by noise. For example, information flow is initiated by binding of extracellular ... |
