Multiple barriers in forced rupture of protein complexes
Multiple barriers forced rupture of protein complexes Biological Physics
font style='font-size:12px;'>
2012/4/20
Curvatures in the most probable rupture force ($f^*$) versus log-loading rate ($\log{r_f}$) observed in dynamic force spectroscopy (DFS) on biomolecular complexes are interpreted using a one-dimension...
Ageing effects in single particle trajectory averages
Ageing effects single particle trajectory averages Biological Physics
font style='font-size:12px;'>
2012/5/3
We study time averages of single particle trajectories in scale free anomalous diffusion processes, in which the measurement starts at some time t_a>0 after initiation of the process at the time origi...
Bio-Polymer Hairpin Loops Sustained by Polarons
Bio-Polymer Hairpin Loops Sustained Polarons Biological Physics
font style='font-size:12px;'>
2012/4/19
We show that polarons can sustain loop-like configurations in flexible bio-polymers and that the size of the loops depend on both the flexural rigidity of the polymer and the electron-phonon coupling ...
Hypoxia and nitrogen processing in the Baltic Sea water column

2014/4/4
Steep redoxclines form between oxic surface water and the stagnant, sulfidic hypolimnion in the eutrophied,
brackish water Baltic Sea. Nitrification, denitrification, and anammox were measured at and...

in a laboratory microcosm. Mineralization of the diatom ...
Optimal Channel Efficiency in a Sensory Network
Optimal Channel Efficiency Sensory Network Biological Physics
font style='font-size:12px;'>
2012/5/3
We show that the entropy of the distribution of avalanche lifetimes in the Kinouchi-Copelli model always achieves a maximum jointly with the dynamic range. This is noteworthy and nontrivial because wh...

DNA Self-Assembly Computation Studied Coarse-grained Dynamic Bonded Model Biological Physics
font style='font-size:12px;'>
2012/5/3
We utilize a coarse-grained directional dynamic bonding DNA model [C. Svaneborg, Comp. Phys. Comm. (In Press DOI:10.1016/j.cpc.2012.03.005)] to study DNA self-assembly and DNA computation. In our DNA ...

Length-dependent dynamics of microtubules
Length-dependent dynamics of microtubules Biological Physics
font style='font-size:12px;'>
2012/5/3
Certain regulatory proteins influence the polymerization dynamics of microtubules by inducing catastrophe with a rate that depends on the microtubule length. Using a discrete formulation, here we show...
