Flexible random graph modeling for cell-cell interactions
Mike van Santvoort, Pim van der Hoorn
In this paper we explore generalisations to a random digraph model designed for modelling cell-cell interactions (RaCInG). In its baseline model -- tested both theoretically and in…
Projective limits of probabilistic symmetries and their applications to random graph limits
Pim van der Hoorn, Huck Stepanyants, Dmitri Krioukov
We couple projective limits of probability measures to direct limits of their symmetry groups. We show that the direct limit group is the group of symmetries of the projective limi…
Limiting Behavior of Degree-Degree Metrics under Local Convergence in Probability
Andrei-Eugeniu Patularu, Pim van der Hoorn
This paper investigates the limiting behaviour of degree-degree correlation metrics for sequences of random graphs under a general assumption of local convergence in probability. W…
Automatic Identification of Traps in Molecular Charge Transport Networks of Organic Semiconductors
Zhongquan Chen, Pim van der Hoorn, Björn Baumeier
This paper introduces a method to identify traps in molecular charge transport networks as obtained by multiscale modeling of organic semiconductors. Depending on the materials, tr…
A Graph Random Walk Method for Calculating Time-of-Flight Charge Mobility in Organic Semiconductors from Multiscale Simulations
Zhongquan Chen, Pim van der Hoorn, Björn Baumeier
We present a graph random walk (GRW) method for the study of charge transport properties of complex molecular materials in the time-of-flight regime. The molecules forming the mate…
