Given a social network, the Influence Maximization (InfMax) problem seeks a seed set of k people that maximizes the expected influence for a viral marketing campaign. However, a solution for a particular seed size k is often not enough to make an informed choice regarding budget and cost-effectiveness. In this ...

Given an aftermath of a cascade in the network, i.e. a set V I of "infected" nodes after an epidemic outbreak or a propagation of rumors/worms/viruses, how can we infer the sources of the cascade? Answering this challenging question is critical for computer forensic, vulnerability analysis, and risk management. Despite ...

Gene regulatory networks (GRNs) possess an important structural property; they are sparse and resilient, with a robust topology that affords protection against random "attacks" (e.g., gene deletions). However, such networks exhibit optimal or near-optimal topological features not present in other scale-free networks. This paper utilizes an integer linear program formulation ...

Biological network topologies are known to be robust despite internal and external perturbances. Motifs such as feed-forward loop and bifan have been marked to contribute to structural and functional significance. While network characteristics such as network density, average shortest path, and centrality measures etc., have been well studied, modular characteristics ...

Self-assembly is a ubiquitous, naturally occurring, robust process in many living organisms. Microtubule, a self-organization system assembles itself into functional units by attaching to cellular structures. Modeling microtubule self-organization is of interest as microtubule forms a network of protein filaments that is critical to many processes in eukaryotic cells. In ...

miRNAs (non-coding RNAs of ~20--22 nt size) exhibit a self-regulatory mechanism through which they act as positive/negative regulators of expression of genes and other miRNAs. This has direct implications in the regulation of various signaling pathways and types of cancers. We use information diffusion theory to quantify influence diffusion in ...

Transcriptional motifs are smaller subnetworks found within the gene-regulatory networks of many organisms in larger abundance than can be explained by chance alone. The feed-forward loop is one such three-node motif, wherein one top-level protein regulates the expression of a target gene either directly, or indirectly through an intermediate regulator ...

Motifs and degree distribution in transcriptional regulatory networks play an important role towards their faulttolerance and efficient information transport.

Social network analytic approaches have been previously proposed to identifying key metrics of physician care coordination [1]. Optimizing care coordination among physicians is a primary national concern for which yields significant cuts in medical care costs.

Structural analysis over well studied transcriptional regulatory networks indicates that these complex networks are made up of small set of reoccurring patterns called motifs. While information theoretic approaches have been immensely popular, these approaches rely on inferring the regulatory networks by aggregating pair-wise interactions. In this paper, we propose novel ...

Proteins search along DNA for targets (e.g. transcription initiation sequences) through a combination of sliding, jumping, and intersegment transfers, wherein the sliding process proceeds until the protein-DNA complex dissociates. As such, we propose a diffusion-reaction model of the sliding phase of a total search process, and study the effect of ...
