    Temporal dynamics of streamflow: application of complex networks by Xudong Han, Bellie Sivakumar, Fitsum M. Woldmeskel, Milena Guerra de Aguilar

    Published 2018-03-01
    “…The results suggest that (1) there are only a few very significant nodes (years) in the annual streamflow network (degree centrality method); (2) the annual streamflow network is not a classical random graph, but may be a small-world network or scale-free network (clustering coefficient method); and (3) the network exhibits a combination of exponential and power-law distribution (degree distribution method). …”

    Formation of trade networks by economies of scale and product differentiation by Chengyuan Han, Malte Schröder, Dirk Witthaut, Philipp C Böttcher

    Published 2023-01-01
    “…Economic networks are formed by decisions of individual agents and thus not properly described by established random graph models. In this article, we establish a model for the emergence of trade networks that is based on rational decisions of individual agents. …”

    Model-free reconstruction of excitatory neuronal connectivity from calcium imaging signals. by Olav Stetter, Demian Battaglia, Jordi Soriano, Theo Geisel

    Published 2012-01-01
    “…Finally, we demonstrate the applicability of our method to analyses of real recordings of in vitro disinhibited cortical cultures where we suggest that excitatory connections are characterized by an elevated level of clustering compared to a random graph (although not extreme) and can be markedly non-local.…”

    A Nearly Tight Sum-of-Squares Lower Bound for the Planted Clique Problem by Barak, Boaz, Hopkins, Samuel B., Kothari, Pravesh, Potechin, Aaron, Moitra, Ankur, Kelner, Jonathan Adam

    Published 2018
    “…We prove that with high probability over the choice of a random graph G from the Erds-Rényi distribution G(n,1/2), the n[superscript o(d)]-time degree d Sum-of-Squares semidefinite programming relaxation for the clique problem will give a value of at least n[superscript 1/2-c(d/log n)1/2] for some constant c > 0. …”

    Giant Component in Random Multipartite Graphs with given Degree Sequences by Gamarnik, David, Misra, Sidhant

    Published 2019
    “…We use the exploration process of Molloy and Reed Molloy and Reed (1995) to analyze the size of components in the random graph. The main challenges arise due to the multidimensionality of the random processes involved which prevents us from directly applying the techniques from the standard unipartite case. …”

    Energy-latency tradeoff for in-network function computation in random networks by Balister, Paul, Bollobas, Bela, Anandkumar, Animashree, Willsky, Alan S.

    Published 2012
    “…The policy is then extended to computation of a general class of functions which decompose according to maximal cliques of a proximity graph such as the k-nearest neighbor graph or the geometric random graph. The modified policy achieves order-optimal energy consumption albeit for a limited range of latency constraints.…”

    Queueing system topologies with limited flexibility by Tsitsiklis, John N., Xu, Kuang

    Published 2014
    “…In particular, when d(n) gg ln n , a family of random-graph-based interconnection topologies is (with high probability) capable of stabilizing all admissible arrival rate vectors (under a bounded support assumption), while simultaneously ensuring a diminishing queueing delay, of order ln n/ d(n), as n-> ∞. …”

    Wide-sense stationarity and spectral estimation for generalized graph signal by Jian, Xingchao, Tay, Wee Peng

    Published 2022
    “…We introduce the notion of joint wide-sense stationarity in this generalized GSP (GGSP) framework, which allows us to characterize a random graph process as a combination of uncorrelated oscillation modes across both the vertex and Hilbert space domains. …”

    Friendship based on race or race based on friendship? The co-evoluation of friendships, negative ties and ethnic perceptions in Hungarian school classes by Boda, Z

    Published 2015
    “…For the analyses, we take a social networks approach, estimating exponential random graph and stochastic actor-oriented models. First, we take a look at the state of racial segregation in friendships and negative ties within communities, and we investigate the dynamic processes that have led to the described state. …”

    Structural complexity of one-dimensional random geometric graphs by Badiu, M-A, Coon, JP

    Published 2022

    Uniform random planar graphs with degree constraints by Dowden, C

    Published 2008
    “…Many basic properties of the standard uniform random planar graph $P_{n}$, by which we mean a graph chosen uniformly at random from the set of all planar graphs with vertex set $ { 1,2, ldots, n }$, are now known, and variations on this standard random graph are also attracting interest. Prominent among the work on $P_{n}$ have been asymptotic results for the probability that $P_{n}$ will be connected or contain given components/ subgraphs. …”
