Mechanisms for Differential Protein Production in Toxin–Antitoxin Systems
Toxin–antitoxin (TA) systems are key regulators of bacterial persistence, a multidrug-tolerant state found in bacterial species that is a major contributing factor to the growing human health crisis of antibiotic resistance. ...
Self-assembled PCBM bilayers on graphene and HOPG examined by AFM and STM
In this work we report fabrication and characterization of phenyl-C61-butyric acid methyl ester (PCBM) bilayer structures on graphene and highly oriented pyrolytic graphite (HOPG). Through careful control of the PCBM ...
Membrane targeting of TIRAP is negatively regulated by phosphorylation in its phosphoinositide-binding motif
(Nature Publishing Group, 2017-02-22)
Pathogen-activated Toll-like receptors (TLRs), such as TLR2 and TLR4, dimerize and move laterally across the plasma membrane to phosphatidylinositol (4,5)-bisphosphate-enriched domains. At these sites, TLRs interact with ...
Reversible to irreversible transitions in periodically driven skyrmion systems
(Institute of Physics Publishing, 2019-01-08)
We examine skyrmions driven periodically over random quenched disorder and show that there is a transition from reversible motion to a state in which the skyrmion trajectories are chaotic or irreversible. We find that the ...
Capillary forces on a small particle at a liquid-vapor interface: Theory and simulation
(American Physical Society, 2018-09-24)
Stochastic population dynamics in spatially extended predator-prey systems
Spatially extended population dynamics models that incorporate intrinsic noise serve as case studies for the role of fluctuations and correlations in biological systems. Including spatial structure and stochastic noise in ...
A stochastic analysis of the spatially extended May-Leonard model

Boundary Effects on Population Dynamics in Stochastic Lattice Lotka-Volterra Models
We investigate spatially inhomogeneous versions of the stochastic Lotka-Volterra model for predator-prey competition and coexistence by means of Monte Carlo simulations on a two-dimensional lattice with periodic boundary ...
Dynamical regimes of vortex flow in type-II superconductors with parallel twin boundaries
We explore the dynamics of driven magnetic flux lines in disordered type-II superconductors in the presence of twin boundaries oriented parallel to the direction of the applied magnetic field, using a three-dimensional ...
Effect of the Magnus force on skyrmion relaxation dynamics
