Neuronal Network Analyses in vitro of Acute Individual and Combined Responses to Fluoxetine and Ethanol
Embryonic murine neuronal networks cultured on microelectrode arrays were used to quantify acute electrophysiological effects of fluoxetine and ethanol. Spontaneously active frontal cortex cultures showed highly repeatable, dose-dependent sensitivities to both compounds. Cultures began to respond …

Distribution and population genetics of Northern saw-whet owls in the Southern Appalachians
… 2 were sequenced and analyzed using AMOVAs and network analyses. The Southern Appalachian population was not a subspecies but may be a recent colonization with a small population. Further research into habitat requirements in the Southern Appalachians as well as fecundity and general ecology can …

Helping analysts reason about social network structure: Evidence from training and interactive visualization
Communications through phone, email and social networking create increasingly vast webs of data that can be analyzed for research in areas such as marketing, forecasting, and criminal network analyses. Trained analysts can manipulate algorithmically processed data to find conclusions for further …

Identification and characterization of gene and microRNA networks associated with cancer survival and drug abuse
… of cancer and drug abuse. Functional and network analyses were performed to identify and study targets of microRNA biomarkers associated with glioblastoma multiforme survival within and across race, gender, recurrence, and therapy cohorts. A Cox survival model was applied to profiles from …

Towards an Integrated Model of the Mental Lexicon
… that by representing the mental lexicon as a network, where nodes represent words and edges connect similar words using a metric based on some word feature, a <em>small-world</em> structure is formed. This property, pervasive in many real-world networks, implies processing efficiency and …

Identifying tightly regulated and variably expressed networks by differential rank conservation (DIRAC)
… into an analysis of comparative biological network behaviors. One of the limitations of previous network analyses is that they do not take into account the combinatorial nature of gene interactions within the network. We report here a new technique, Differential Rank Conservation (DIRAC), …

Spatial Ecology and Movement Patterns of Black Drum (Pogonias cromis) and Sheepshead (Archosargus probatocephalus) in Mississippi Sound
… patterns were analyzed using residency indices, network metrics, and environmental covariates, while Sheepshead maturity was inferred using size-based logistic regressions. Results indicated generally strong site fidelity, but with seasonal reductions in residency during known spawning months, …

Computing stationary distribution locally
… whether in statistical inference problems, or in network analyses. Standard methods involve large matrix multiplications as in power iterations, or long simulations of random walks to sample states from the stationary distribution, as in Markov Chain Monte Carlo (MCMC). However, these approaches …
