Phys Rev E Stat Nonlin Soft Matter Phys. 2011 Jun;83(6):066116. doi: 10.1103/PhysRevE.83.066116. Epub 2011 Jun 28.

Cultural competition has throughout our history shaped and reshaped the geography of boundaries between humans. Language and culture are intimately connected and linguists often use distinctive keywords to quantify the dynamics of information spreading in societies harboring strong culture...

Front Microbiol. 2015 Jun 02;6:528. doi: 10.3389/fmicb.2015.00528. eCollection 2015.

Restriction modification (RM) systems provide protection against a broad spectrum of phages. However, the likelihood of a phage permanently bypassing this can be as high as 0.1 per infection (Korona et al., 1993) which makes for a relatively weak...

Effect of supercoiling on the λ switch.

Bacteriophage

Norregaard K, Andersson M, Sneppen K, Nielsen PE, Brown S, Oddershede LB.
PMID: 24386605
Bacteriophage. 2014 Jan 01;4(1):e27517. doi: 10.4161/bact.27517.

The lysogenic state of the λ switch is exceptionally stable, still, it is capable of responding to DNA-damage and rapidly enter the lytic state. We invented an assay where PNA mediated tethering of a plasmid allowed for single molecule...

Degree landscapes in scale-free networks.

We generalize the degree-organizational view of real-world networks with broad degree distributions in a landscape analog with mountains (high-degree nodes) and valleys (low-degree nodes). For example, correlated degrees between adjacent nodes correspond to smooth landscapes (social networks), hierarchical networks...

New J Phys. 2007 Aug 17;9:273. doi: 10.1088/1367-2630/9/8/273.

Using an example of physical interactions between proteins, we study how a perturbation propagates in the equilibrium of a network of reversible reactions governed by the law of mass action. We introduce a matrix formalism to describe the linear...

The distribution of information is essential for a living system's ability to coordinate and adapt. Random walkers are often used to model this distribution process and, in doing so, one effectively assumes that information maintains its relevance over time....
