Dynamical and Structural Modularity of Discrete Regulatory Networks
Heike Siebert
A biological regulatory network can be modeled as a discrete function that contains all available information on network component interactions. From this function we can derive a…
Orbital-free energy functional for electrons in two dimensions
S. Pittalis, E. Rasanen
We derive a non-empirical, orbital-free density functional for the total energy of interacting electrons in two dimensions. The functional consists of a local formula for the inter…
Gaussian approximations for the exchange-energy functional of current-carrying states: Applications to two-dimensional systems
S. Pittalis, E. Rasanen, E. K. U. Gross
Electronic structure calculations are routinely carried out within the framework of density-functional theory, often with great success. For electrons in reduced dimensions, howeve…
A Lost Counterexample and a Problem on Illuminated Polytopes
Ronald F. Wotzlaw, Günter M. Ziegler
In a Note added in proof to a 1984 paper, Daniel A. Marcus claimed to have a counterexample to his conjecture that a minimal positively k-spanning vector configuration in R^m has s…
Finding Fullerene Patches in Polynomial Time
Paul Bonsma, Felix Breuer
We consider the following question, motivated by the enumeration of fullerenes. A fullerene patch is a 2-connected plane graph G in which inner faces have length 5 or 6, non-bounda…
Persistent currents in normal metal rings: comparing high-precision experiment with theory
A. C. Bleszynski-Jayich, W. E. Shanks, B. Peaudecerf +4
Quantum mechanics predicts that the equilibrium state of a resistive electrical circuit contains a dissipationless current. This persistent current has been the focus of considerab…
