A Model of Shadow Banking
(Wiley Blackwell (Blackwell Publishing), 2013)We present a model of shadow banking in which banks originate and trade loans, assemble them into diversified portfolios, and finance these portfolios externally with riskless debt. In this model: outside investor wealth ... -
A Model of Social Interactions and Endogenous Poverty Traps
(SAGE Publications, 2007)This paper develops a model of social interactions and endogenous poverty traps. The key idea is captured in a framework in which the likelihood of future social interactions with members of one's group is partly determined ... -
A Model of the Political Economy of the United States
(Cambridge University Press, 1993)We develop and test a model of joint determination of economic growth and national election results in the United States. The formal model, which combines developments in the rational choice analysis of the behavior of ... -
Model selection principles in misspecified models
(Wiley-Blackwell, 2013)Model selection is of fundamental importance to high dimensional modelling featured in many contemporary applications. Classical principles of model selection include the Bayesian principle and the Kullback–Leibler divergence ... -
Model Transcriptional Networks with Continuously Varying Expression Levels
(BioMed Central, 2011)Background: At a time when genomes are being sequenced by the hundreds, much attention has shifted from identifying genes and phenotypes to understanding the networks of interactions among genes. We developed a gene network ... -
Model-Based Analysis of Two-Color Arrays (MA2C)
(BioMed Central, 2007)A novel normalization method based on the GC content of probes is developed for two-color tiling arrays. The proposed method, together with robust estimates of the model parameters, is shown to perform superbly on published ... -
Model-Independent Predictions for Smooth Cosmic Acceleration Scenarios
(American Physical Society (APS), 2018-08-30)Through likelihood analyses of both current and future data that constrain both the expansion history of the Universe and the clustering of matter fluctuations, we provide falsifiable predictions for three broad classes ... -
Model-independent test of the truncated crater function theory of surface morphology evolution during ion bombardment
(American Physical Society (APS), 2014)A broad class of “local response” theories seeks to predict morphology evolution during energetic particle irradiation in terms of average surface height response to individual impacts—an approach that has been generalized ... -
Modeling a Growth Instability in Stressed Boron Doped Silicon
(Applied Computational Research Society; Nano science and technology institute, 2002)The effects of rate-enhancing dopants and externally applied stress on interfacial growth during silicon crystallization are modeled using advanced numerical methods. The boron doped crystalline Si is modeled as an isotropic ... -
Modeling Analysis of Primary Controls on Net Ecosystem Productivity of Seven Boreal and Temperate Coniferous Forests Across a Continental Transect
(Blackwell Publishing, 2008)Process-based models are effective tools to synthesize and/or extrapolate measured carbon (C) exchanges from individual sites to large scales. In this study, we used a C- and nitrogen (N)-cycle coupled ecosystem model named ... -
Modeling and Decoding Motor Cortical Activity Using a Switching Kalman Filter
(Institute of Electrical and Electronics Engineers, 2004)We present a switching Kalman filter model for the real-time inference of hand kinematics from a population of motor cortical neurons. Firing rates are modeled as a Gaussian mixture where the mean of each Gaussian component ... -
Modeling and Inferring Cleavage Patterns in Proliferating Epithelia
(Public Library of Science, 2009)The regulation of cleavage plane orientation is one of the key mechanisms driving epithelial morphogenesis. Still, many aspects of the relationship between local cleavage patterns and tissue-level properties remain poorly ... -
Modeling Coherent Anti-Stokes Raman Scattering with Time-Dependent Density Functional Theory: Vacuum and Surface Enhancement
(American Chemical Society, 2011)We present the first density functional simulations of coherent anti-Stokes Raman scattering (CARS) and an analysis of the chemical effects upon binding to a metal surface. Spectra are obtained from first-principles ... -
Modeling contextual effects using individual-level data and without aggregation: an illustration of multilevel factor analysis (MLFA) with collective efficacy
(BioMed Central, 2015)Population health scientists increasingly study how contextual-level attributes affect individual health. A major challenge in this domain relates to measurement, i.e., how best to measure and create variables that capture ... -
Modeling Convergent ON and OFF Pathways in the Early Visual System
(Springer-Verlag, 2008)For understanding the computation and function of single neurons in sensory systems, one needs to investigate how sensory stimuli are related to a neuron’s response and which biological mechanisms underlie this relationship. ... -
Modeling Fluid Flow in Medullosa, an Anatomically Unusual Carboniferous Seed Plant
(Paleontological Society, 2008)<i>Medullosa</i> stands apart from most Paleozoic seed plants in its combination of large leaf area, complex vascular structure, and extremely large water-conducting cells. To investigate the hydraulic consequences of these ... -
Modeling foundation species in food webs
(Ecological Society of America, 2013)Foundation species are basal species that play an important role in determining community composition by physically structuring ecosystems and modulating ecosystem processes. Foundation species largely operate via non-trophic ... -
A Modeling Framework for Jamming Structures
(Wiley, 2021-02-10)Jamming is a structural phenomenon that provides tunable mechanical behavior. A jamming structure typically consists of a collection of elements with a low effective stiffness and damping. When a pressure gradient, such ...
