Mixed Effects Models for Resampled Network Statistics Improves Statistical Power to Find Differences in Multi-Subject Functional Connectivity
(2016)Many complex brain disorders, such as autism spectrum disorders, exhibit a wide range of symptoms and disability. To understand how brain communication is impaired in such conditions, functional connectivity studies seek ... -
Model-based clustering of large networks
(2013)We describe a network clustering framework, based on finite mixture models, that can be applied to discrete-valued networks with hundreds of thousands of nodes and billions of edge variables. Relative to other recent ... -
Modeling neutral evolution using an in nite-allele Markov branching process
(2013)We consider an in nite-allele Markov branching process (IAMBP). Our main focus is the frequency spectrum of this process, i.e., the proportion of alleles having a given number of copies at a speci ed time point. We derive ... -
Modeling the Natural History and Detection of Lung Cancer Based on Smoking Behavior
(2014)In this study, we developed a method for modeling the progression and detection of lung cancer based on the smoking behavior at an individual level. The model allows obtaining the characteristics of lung cancer in a ... -
Molecular pathway identification using biological network-regularized logistic models
(2013)Background: Selecting genes and pathways indicative of disease is a central problem in computational biology. This problem is especially challenging when parsing multi-dimensional genomic data. A number of tools, such as ... -
Multitype Bellman-Harris branching model provides biological predictors of early stages of adult hippocampal neurogenesis
(2017-10-03)Abstract Background Adult hippocampal neurogenesis, the process of formation of new neurons, occurs throughout life in the hippocampus. New neurons have been associated with ... -
A Network Biology Approach Identifies Molecular Cross-Talk between Normal Prostate Epithelial and Prostate Carcinoma Cells
(2016)The advent of functional genomics has enabled the genome-wide characterization of the molecular state of cells and tissues, virtually at every level of biological organization. The difficulty in organizing and mining this ... -
Neural Networks of Colored Sequence Synesthesia
(2013)Synesthesia is a condition in which normal stimuli can trigger anomalous associations. In this study,weexploit synesthesia to understand how the synesthetic experience can be explained by subtle changes in network properties. ... -
NF-κB and IRF pathways: cross-regulation on target genes promoter level
(2015)Background: The NF-κB and IRF transcription factor families are major players in inflammation and antiviral response and act as two major effectors of the innate immune response (IIR). The regulatory mechanisms of activation ... -
On the Reproducibility of TCGA Ovarian Cancer MicroRNA Profiles
(2014)Dysregulated microRNA (miRNA) expression is a well-established feature of human cancer. However, the role of specific miRNAs in determining cancer outcomes remains unclear. Using Level 3 expression data from the Cancer ... -
On the time for Brownian motion to visit every point on a circle
(2016)Consider a Wiener process W on a circle of circumference L. We prove the rather surprising result that the Laplace transform of the distribution of the first time, θL, when the Wiener process has visited every point of the ... -
Point source influence on observed extreme pollution levels in a monitoring network
(2014)This paper presents a strategy to quantify the influence major point sources in a region have on extreme pollution values observed at each of the monitors in the network. We focus on the number of hours in a day the levels ... -
Prediction using hierarchical data: Applications for automated detection of cervical cancer
(2015)Although the Papanicolaou smear has been successful in decreasing cervical cancer incidence in the developed world, there exist many challenges for implementation in the developing world. Quantitative cytology, a semi-automated ... -
Prenatal exposure to cadmium and cotinine and CpG island DNA methylation in mother-infant pairs
(2015)A precise biological mechanism by which cadmium acts as a developmental toxicant is unknown but is suggested to include an epigenetic basis. In prior work, we analyzed CpG island methylation levels within gene promoters ... -
Proteomic analyses reveal distinct chromatin‐associated and soluble transcription factor complexes
(2015)The current knowledge on how transcription factors (TFs), the ultimate targets and executors of cellular signalling pathways, are regulated by protein–protein interactions remains limited. Here, we performed proteomics ... -
Regularized partial least squares with an application to NMR spectroscopy
(2013)High-dimensional data common in genomics, proteomics, and chemometrics often contains complicated correlation structures. Recently, partial least squares (PLS) and Sparse PLS methods have gained attention in these areas ... -
Resting state functional MRI reveals abnormal network connectivity in neurofibromatosis 1
(2015)Neurofibromatosis type I (NF1) is a genetic disorder caused by mutations in the neurofibromin 1 gene at locus 17q11.2. Individuals with NF1 have an increased incidence of learning disabilities, attention deficits, and ... -
Robust fitting of a Weibull model with optional censoring
(2013)The Weibull family is widely used to model failure data, or lifetime data, although the classical two-parameter Weibull distribution is limited to positive data and monotone failure rate. The parameters of the Weibull model ... -
Simulation of Leveraged ETF Volatility Using Nonparametric Density Estimation
(2015)Leveraged Exchange Traded Funds (LETFs) are constructed to provide the indicated leverage multiple of the daily total return on an underlying index. LETFs may perform as expected on a daily basis; however, fund issuers ...
