Cationic DMPC/DMTAP Lipid Bilayers: Molecular Dynamics Study
A. A. Gurtovenko, Michael Patra, Mikko Karttunen +1
Cationic lipid membranes are known to form compact complexes with DNA and to be effective as gene delivery agents both in vitro and in vivo. Here we employ molecular dynamics simul…
Crumpling of a stiff tethered membrane
J. A. Astrom, J. Timonen, Mikko Karttunen
first-principles numerical simulation model for crumpling of a stiff tethered membrane is introduced. In our model membranes, wrinkles, ridge formation, ridge collapse, as well as…
Dimensionality effects in Turing pattern formation
Teemu Leppanen, Mikko Karttunen, Kimmo Kaski +1
The problem of morphogenesis and Turing instability are revisited from the point of view of dimensionality effects. First the linear analysis of a generic Turing model is elaborate…
Lipid bilayers driven to a wrong lane in molecular dynamics simulations by truncation of long-range electrostatic interactions
Michael Patra, Mikko Karttunen, Marja T. Hyvonen +2
This paper has been withdrawn.
On coarse-graining by the Inverse Monte Carlo method: Dissipative Particle Dynamics simulations made to a precise tool in soft matter modeling
A. P. Lyubartsev, M. Karttunen, I. Vattulainen +1
We present a promising coarse-graining strategy for linking micro- and mesoscales of soft matter systems. The approach is based on effective pairwise interaction potentials obtaine…
Collapses and explosions in self-gravitating systems
I. Ispolatov, M. Karttunen
Collapse and reverse to collapse explosion transition in self-gravitating systems are studied by molecular dynamics simulations. A microcanonical ensemble of point particles confin…
How would you integrate the equations of motion in dissipative particle dynamics simulations?
P. Nikunen, M. Karttunen, I. Vattulainen
In this work we assess the quality and performance of several novel dissipative particle dynamics integration schemes that have not previously been tested independently. Based on a…
Connectivity of Turing structures
Teemu Leppanen, Mikko Karttunen, R. A. Barrio +1
It is well-known that in two dimensions Turing systems produce spots, stripes and labyrinthine patterns, and in three dimensions lamellar and spherical structures or their combinat…
