Multiple barriers in forced rupture of protein complexes
Multiple barriers forced rupture of protein complexes Biological Physics
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
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
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
Hypoxia nitrogen processing 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...
Meiofauna enhances organic matter mineralization in soft sediment ecosystems
soft sediment ecosystems Meiofauna enhances
2014/4/4
We investigated the influence of meiofauna on the benthic decomposition of a radiolabeled diatom bloom by
measuring the production of 14
CO2
in a laboratory microcosm. Mineralization of the diatom ...
Optimal Channel Efficiency in a Sensory Network
Optimal Channel Efficiency Sensory Network Biological Physics
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 and Computation Studied with a Coarse-grained Dynamic Bonded Model
DNA Self-Assembly Computation Studied Coarse-grained Dynamic Bonded Model Biological Physics
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 ...
Stripe formation in bacterial systems with density-suppressed motility
Stripe formation bacterial systems density-suppressed motility Biological Physics
2012/5/3
Engineered bacteria in which motility is reduced by local cell density generate periodic stripes of high and low density when spotted on agar plates. We study theoretically the origin and mechanism of...

Length-dependent dynamics of microtubules
Length-dependent dynamics of microtubules Biological Physics
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...
Selecting fast folding proteins by their rate of convergence
fast folding proteins their rate of convergence Biological Physics
2012/5/3
We propose a general method for predicting potentially good folders from a given number of amino acid sequences. Our approach is based on the calculation of the rate of convergence of each amino acid ...

Chemo-mechanical instabilities polarizable active layers Biological Physics
2012/4/19
We formulate and explore a generic continuum model of a polarizable active layer with neo-Hookean elasticity and chemo-mechanical interactions. Homogeneous solutions of the model equations exhibit a s...

Optimal Pacing for Running 400 m and 800 m Track Races
Optimal Pacing Popular Physics Biological Physics
2012/4/19
Physicists seeking to understand complex biological systems often find it rewarding to create simple "toy models" that reproduce system behavior. Here a toy model is used to understand a puzzling phen...
A theorem for the thermodynamics of chemical reaction networks at steady state
thermodynamics of chemical reaction networks steady state Biological Physics
2012/5/3
In this article the Gordan theorem is applied to the thermodynamics of a chemical reaction network at steady state. From a theoretical viewpoint it states that the exclusion (presence) of closed react...
