Probabilistic Prediction of Post-disaster Functionality Loss of shelby_county_water_network_pwsa_epsa_newCommunity Building Portfolios Considering Utility Availabilities

This study proposes a probabilistic framework for estimating functionality loss of community building portfolios following a disaster. The detailed datasets of nodes and arcs associated with the power, water, and interdependencies between the two for Shelby County Tennessee are available here: Shelby County Utilities data.  The interdependencies are based on the defined electric power service area (EPSA) of power substations and the associated water pumps that are located within the EPSA.

Variable neighborhood search for reverse engineering of gene regulatory networks

In this paper, the authors introduce a new search heuristic, Divided Neighborhood Exploration Search, to be used with inference algorithms such as Bayesian networks to improve on the reverse engineering of gene regulatory networks. The approach systematically moves through the search space to find topologies representative of gene regulatory networks that are more likely to explain microarray data. The novel method leverages the existing open-source software Banjo: Bayesian Network Inference with Java Objects
