Microscopic implications of S-DNA
Stephen Whitelam, Phillip L. Geissler, Sander Pronk
Recent experiments [J. van Mameren et al. PNAS 106, 18231 (2009)] provide a detailed spatial picture of overstretched DNA, showing that under certain conditions the two strands of…
Faster strain fluctuation methods through partial volume updates
Sander Pronk, Phillip L. Geissler
Elastic systems that are spatially heterogeneous in their mechanical response pose special challenges for molecular simulations. Standard methods for sampling thermal fluctuations…
Stretching chimeric DNA: a test for the putative S-form
Stephen Whitelam, Sander Pronk, Phillip L. Geissler
Double-stranded DNA `overstretches' at a pulling force of about 65 pN, increasing in length by a factor of 1.7. The nature of the overstretched state is unknown, despite its consid…
The limits of filopodium stability
Sander Pronk, Phillip L. Geissler, Daniel A. Fletcher
Filopodia are long, finger-like membrane tubes supported by cytoskeletal filaments. Their shape is determined by the stiffness of the actin filament bundles found inside them and b…
There and (slowly) back again: Entropy-driven hysteresis in a model of DNA overstretching
Stephen Whitelam, Sander Pronk, Phillip L. Geissler
When pulled along its axis, double-stranded DNA elongates abruptly at a force of about 65 pN. Two physical pictures have been developed to describe this overstretched state. The fi…
Melting of Polydisperse Hard Disks
Sander Pronk, Daan Frenkel
The melting of a polydisperse hard disk system is investigated by Monte Carlo simulations in the semigrand canonical ensemble. This is done in the context of possible continuous me…
