Critical Node Identifcation for accessing network vulnerability, a necessary consideration
Timely identification of critical nodes is crucial for assessing network vulnerability and survivability. This thesis presents two new approaches for the identification of critical nodes in a network with the first being an intuition based approach and the second being build on a mathematical …

Critical Node Analysis for Water Distribution System Using Flow Distribution
… study aimed to develop a method that locates critical nodes without hydraulic analysis of every failure scenario, applicable for any size WDS, incorporates critical infrastructure, and capable of verifying method accuracy. The Flow Distribution method is the application of the gravity model, …

Understanding and Hardening Blockchain Network Security Against Denial of Service Attacks
… against Denial-of-Service (DoS) attacks are thus critical to the well-being of blockchain participants. Existing research has examined blockchain system security in various system components, including mining incentives, consensus protocols, and applications such as smart contracts. However, the …

Gene Regulatory Networks in Striated Muscle Pathologies
… infarction. In this process, we elucidated critical nodes in complex pathways that can be manipulated to derail the pathological process of FN-RMS or stimulate regeneration and repair in postnatal hearts.

Cascading Events in the Aftermath of a Targeted Physical Attack on the Power Grid
… the problem of identifying a set of k critical nodes, whose failure/attack leads to the maximum adverse impact on the power system has been analyzed in detail. It is observed that a greedy approach yields node sets with higher criticality than a degree-based approach, which has been …

High Throughput Screening for Small Molecule Interactions with Nucleic Acid Binding Proteins
Nucleic acid binding proteins are critical nodes in almost all cell signaling networks. Cell network architecture depends on highly regulated nucleic acid binding to determine cell identity, developmental trajectory, environmental response, and homeostasis. These proteins govern all aspects of …

Energy efficiency in data collection wireless sensor networks
… to reduce the data traffic processed in critical nodes, independent of their hardware platform, improving their energy consumption and extending the network lifetime. We propose a new routing strategy that extends traditional cost-based routing protocols and improves their energy …

Enhancing network robustness via shielding
Shielding critical links enhances network robustness and provides a new way of designing robust networks. We first consider shielding critical links to guarantee network connectivity after any failure under geographical and general failure models. We develop a mixed integer linear program (MILP) to …

Deciphering The C-Type Lectin Receptor Signaling Pathway In Macrophages In Response to Candida Albicans
… immune response<em>. </em>TAK1 and TRAF6 are critical nodes in NF-κB and MAPK activation downstream of immune surveillance and may be critical to the signaling cascade initiated by C-type lectin receptors in response to <em>C.</em> <em>albicans</em>. Macrophages derived from both TAK1 and …

Risk Assessment and Management of Petroleum Transportation Systems Operations
… help decision makers to measure and detect the critical nodes (ports and transportation routes) within PTNs. The fifth phase uses an Evidential Reasoning (ER) approach and Intelligence Decision System (IDS) software, to assess hazards influencing on PTSs as one complete system. This research …

Energy efficient organization and modeling of wireless sensor networks
… by extending the lifetime of the communication critical nodes and as a result the overall network's operation, is considered and studied. Based on the data-centric characteristic of wireless sensor networks, an efficient Quality of Service (QoS)-constrained data aggregation and processing …

Risk based models for the optimization of oil and gas supply chain critical infrastructure
… were developed for the oil and gas supply chain critical infrastructure. First, the events and activities were categorized as short term and long term, and their risk ratings derived, by analyzing data from past events and site visits. The result showed that events like the Israel -- Arab war, …

Analysis and Optimization of Networks in Overload
… the ingress and egress rates of different nodes at the same layer of the network. We further generalize them to queue-proportional policies, which asymptotically minimizes queueing delay based on the real-time queue backlogs agnostic of packet arrival rates. (ii) Fairness: We identify that …
