A Quantitative Modular Modeling Approach Reveals the Effects of Different A20 Feedback Implementations for the NF-kB Signaling Dynamics

Janina Mothes, Inbal Ipenberg, Seda Çöl Arslan, Uwe Benary, Claus Scheidereit, Jana Wolf
2020 Frontiers in Physiology  
These time course data indicate that only one of the A20 feedback models appropriately describes the impact of A20 on the NF-κB dynamics in this cell type.  ...  A number of pathway models has been developed implementing the A20 effect in different ways. We here focus on the question how different A20 feedback implementations impact the dynamics of NF-κB.  ...  Secondly, the core processes of this model perfectly match the reactions of the core module of our models A-C.  ...

Stable centred tetragonal phases in the hard core Yukawa system

Gernot J Pauschenwein, Gerhard Kahl
2009 Journal of Physics: Condensed Matter  
The hard core Yukawa system, consisting of particles with an impenetrable core and interacting via a repulsive Yukawa pair potential, is known to solidify either in a bcc or fcc crystal.  ...  Using optimization strategies based on genetic algorithms we give evidence that at zero temperature an additional centred tetragonal phase structure in the range of high packing fractions emerges.  ...  The authors are indebted to Antti-Pekka Hynninen and Marjolein Dijkstra for providing data published in [18] and presented in figure 4(a) .  ...

Nonextensive Theory of Dark Matter and Gas Density Profiles

M. P. Leubner
2005 Astrophysical Journal  
Pronounced core-halo patterns of dark matter and gas density profiles, observed in relaxed galaxies and clusters, were hitherto fitted by empirical power-laws.  ...  On the other hand, similar features are well known from astrophysical plasma environments, subject to long-range interactions, modeled in the context of nonextensive entropy generalization.  ...  In this situation a single parameter κ characterizes the degree of nonextensivity or coupling within the system.  ...
