    • A 2-D simulation study on CO2ᅠsoluble surfactant for foam enhanced oil recovery 

      Zeng, Yongchao; Farajzadeh, Rouhi; Biswal, Sibani L.; Hirasaki, George J. (2019)
      This paper probes the transport of CO2ᅠsoluble surfactant for foaming in porous media. We numerically investigate the effect of surfactant partitioning between the aqueous phase and the gaseous phase on foam transport for subsurface applications when the surfactant is injected in the CO2ᅠphase. A 2-D reservoir simulation is developed to quantify the ...
    • A 3D printable perfused hydrogel vascular model to assay ultrasound-induced permeability 

      Royse, Madison K.; Means, A. Kristen; Calderon, Gisele A.; Kinstlinger, Ian S.; He, Yufang; (2022)
      The development of an in vitro model to study vascular permeability is vital for clinical applications such as the targeted delivery of therapeutics. This work demonstrates the use of a perfusion-based 3D printable hydrogel vascular model as an assessment for endothelial permeability and its barrier function. Aside from providing a platform that more ...
    • A 5-km-thick reservoir with > 380,000 km3 of magma within the ancient Earth's crust 

      Latypov, Rais; Chistyakova, Sofya; Hornsey, Richard A.; Costin, Gelu; van der Merwe, Mauritz (2022)
      Several recent studies have argued that large, long-lived and molten magma chambers may not occur in the shallow Earth’s crust. Here we present, however, field-based observations from the Bushveld Complex that provide evidence to the contrary. In the eastern part of the complex, the magmatic layering continuously drapes across a ~ 4-km-high sloping ...
    • A Ball and Beam Module for a Haptic Paddle Education Platform 

      Rose, Chad G.; Bucki, Nathan; O’Malley, Marcia K. (2017)
      Single degree of freedom force-feedback mechatronic devices, often called haptic paddles, are used in university curriculum as well as massive open online courses (MOOCs). While devices differ based on the goals of a given course, broadly speaking they provide hands-on learning for students studying mechatronics and dynamics. We introduce the third ...
    • A Bayesian approach for capturing daily heterogeneity in intra-daily durations time series 

      Brownlees, Christian T.; Vannucci, Marina (2013)
      Intra-daily financial durations time series typically exhibit evidence of long range dependence. This has motivated the introduction of models able to reproduce this stylized fact, like the Fractionally Integrated Autoregressive Conditional Duration Model. In this work we introduce a novel specification able to capture long range dependence. We propose ...
    • A Bayesian Integrative Model for Genetical Genomics with Spatially Informed Variable Selection 

      Cassese, Alberto; Guindani, Michele; Vannucci, Marina (2014)
      We consider a Bayesian hierarchical model for the integration of gene expression levels with comparative genomic hybridization (CGH) array measurements collected on the same subjects. The approach defines a measurement error model that relates the gene expression levels to latent copy number states. In turn, the latent states are related to the ...
    • A Bayesian Multivariate Functional Dynamic Linear Model 

      Kowal, Daniel R.; Matteson, David S.; Ruppert, David (2017)
      We present a Bayesian approach for modeling multivariate, dependent functional data. To account for the three dominant structural features in the data—functional, time dependent, and multivariate components—we extend hierarchical dynamic linear models for multivariate time series to the functional data setting. We also develop Bayesian spline theory ...
    • A Bayesian Nonparametric Spiked Process Prior for Dynamic Model Selection 

      Cassese, Alberto; Zhu, Weixuan; Guindani, Michele; Vannucci, Marina (2019)
      In many applications, investigators monitor processes that vary in space and time, with the goal of identifying temporally persistent and spatially localized departures from a baseline or “normal” behavior. In this manuscript, we consider the monitoring of pneumonia and influenza (P&I) mortality, to detect influenza outbreaks in the continental United ...
    • A behavioral approach to positive interpolation 

      Mayo, Andrew (2005)
      We study interpolation by positive functions from a behavioural point of view. In particular, by considering the notion of mirror image data, the interpolation problem with passivity constraint is transformed into an unconstrained behavioural modeling one. It will be shown that the generating system for this problem has to be unitary with respect to ...

    • A Block Coordinate Descent Method for Multi-Convex Optimization with Applications to Nonnegative Tensor Factorization and Completion 

      Xu, Yangyang; Yin, Wotao (2012-08)
      This paper considers block multi-convex optimization, where the feasible set and objective function are generally non-convex but convex in each block of variables. We review some of its interesting examples and propose a generalized block coordinate descent method. Under certain conditions, we show that any limit point satisfies the Nash equilibrium ...
    • A Bottom-Up Infrastructure Strategy for American Renewal 

      Cisneros, Henry G.; Fulton, William; Clark, J.H. Cullum; Hendricks, David; Davis, Victoria; (2021)
      As the United States emerges from the pandemic, it is clear that the nation faces a number of major challenges. This report and an accompanying interactive map explore the infrastructure priorities identified by local and regional leaders around the nation. The report also outlines an unconventional bottom-up approach to improvements.
    • A Branch and Cut Algorithm for Nonconvex Quadratically Constrained Quadratic Programming 

      Audet, Charles; Hansen, Pierre; Jaumard, Brigitte; Savard, Gilles (1999-01)
      We present a branch and cut algorithm that yields in finite time, a globally epsilon-optimal solution (with respect to feasibility and optimality) of the nonconvex quadratically constrained quadratic programming problem. The idea is to estimate all quadratic terms by successive linearizations within a branching tree using Reformulation-Linearization ...
