  • Garcia, Odd Erik (American Physical Society, 2012-06)
    Single-point measurements of fluctuations in the scrape-off layer of magnetized plasmas are generally found to be dominated by large-amplitude bursts which are associated with radial motion of bloblike structures. A ...
  • Bufetov, Alexey; Gorin, Vadim (Oxford University Press (OUP), 2015-03)
    We show that the order on probability measures, inherited from the dominance order on the Young diagrams, is preserved under natural maps reducing the number of boxes in a diagram by 1. As a corollary, we give a new proof ...
  • Lim, Sejoon; Balakrishnan, Hari; Gifford, David K.; Madden, Samuel R.; Rus, Daniela L. (Springer Berlin/Heidelberg, 2009-12)
    This paper presents a stochastic motion planning algorithm and its application to traffic navigation. The algorithm copes with the uncertainty of road traffic conditions by stochastic modeling of travel delay on road ...
  • Parpas, Panos; Webster, Mort (Elsevier, 2013-07)
    Long-term planning for electric power systems, or capacity expansion, has traditionally been modeled using simplified models or heuristics to approximate the short-term dynamics. However, current trends such as increasing ...
  • Flotterod, Gunnar; Osorio Pizano, Carolina (Elsevier Science, 2017-05)
    This article considers the stochastic modeling of vehicular network flows, including the analytical approximation of joint queue-length distributions. The article presents two main methodological contributions. First, it ...
  • Castellarnau, Marc; Szeto, Gregory Lee; Su, Hao-wei; Tokatlian, Talar; Love, J. Christopher; Irvine, Darrell J.; Voldman, Joel (Wiley Blackwell, 2014-09)
    This study presents stochastic particle barcoding (SPB), a method for tracking cell identity across bioanalytical platforms. In this approach, single cells or small collections of cells are co-encapsulated within an ...
  • McLaughlin, Dennis; Trefry, M. G.; Lester, D. R.; Metcalfe, G.; Johnston, C. D.; Ord, A. (American Geophysical Union (Wiley platform), 2011-08)
    The aim of this work is to develop a theoretical framework for the analysis of groundwater head oscillations commonly observed in bores near boundaries of surface water bodies that are subject to periodic variations in ...
  • Lee, Chee Kong; Kwek, Leong Chuan; Cao, Jianshu (American Physical Society, 2011-12)
    We study the stochastic resonance of quantum discord (“discord resonance”) in coupled quantum systems and make a comparison with the stochastic resonance of entanglement (“entanglement resonance”). It is found that the ...
  • Govern, Christopher C.; Chakraborty, Arup K. (Public Library of Science, 2013-08)
    Two theories have emerged for the role that stochasticity plays in biological responses: first, that it degrades biological responses, so the performance of biological signaling machinery could be improved by increasing ...
  • Melati, Daniele; Melloni, Andrea; Weng, Tsui-Wei; Daniel, Luca (Walter de Gruyter, 2016-07)
    Manufacturing variations are becoming an unavoidable issue in modern fabrication processes; therefore, it is crucial to be able to include stochastic uncertainties in the design phase. In this paper, integrated photonic ...
  • Borodin, Alexei; Corwin, Ivan; Gorin, Vadim (Duke University Press, 2015-11)
    We study the asymmetric six-vertex model in the quadrant with parameters on the stochastic line. We show that the random height function of the model converges to an explicit deterministic limit shape as the mesh size tends ...
  • Zworski, Maciej; Dyatlov, Semen (IOP Publishing, 2015-09)
    Pollicott-Ruelle resonances for chaotic flows are the characteristic frequencies of correlations. They are typically defined as eigenvalues of the generator of the flow acting on specially designed functional spaces. We ...
  • Fillmore, Christine M.; Jiang, Guozhi; Shapira, Sagi D.; Tao, Kai; Kuperwasser, Charlotte; Lander, Eric S.; Gupta, Piyush (Elsevier, 2011-08)
    Cancer cells within individual tumors often exist in distinct phenotypic states that differ in functional attributes. While cancer cell populations typically display distinctive equilibria in the proportion of cells in ...
  • Zakine, Ruben; van Wijland, Frédéric; Solon, Alexandre; Gingrich, Todd R. (MDPI AG, 2017-04)
    Stirling engine made of a colloidal particle in contact with a nonequilibrium bath is considered and analyzed with the tools of stochastic energetics. We model the bath by non Gaussian persistent noise acting on the colloidal ...
  • Hunter, Ian; Pillai, Priam Vasudevan (Materials Research Society, 2009-01)
    Conducting polymers such as polypyrrole, polythiophene and polyaniline are currently studied as novel biologically inspired actuators. The actuation mechanism of these materials depends upon the motion of ions in and out ...
  • Yao, Guolin; Tyner, Wallace E.; Staples, Mark Douglas; Malina, Robert (BioMed Central, 2017-01)
    Background Alcohol-to-jet (ATJ) is one of the technical feasible biofuel technologies. It produces jet fuel from sugary, starchy, and lignocellulosic biomass, such as sugarcane, corn grain, and switchgrass, via fermentation ...
  • Elfadel, Ibrahim M.; Zhang, Zheng; El Moselhy, Tarek Ali; Daniel, Luca (Institute of Electrical and Electronics Engineers (IEEE), 2013-09)
    Uncertainties have become a major concern in integrated circuit design. In order to avoid the huge number of repeated simulations in conventional Monte Carlo flows, this paper presents an intrusive spectral simulator for ...
  • Zhang, Zheng; Yang, Xiu; Marucci, Giovanni; Maffezzoni, Paolo; Elfadel, Ibrahim Abe M.; Karniadakis, George E.; Daniel, Luca (Institute of Electrical and Electronics Engineers (IEEE), 2014-09)
    Process variations are a major concern in today's chip design since they can significantly degrade chip performance. To predict such degradation, existing circuit and MEMS simulators rely on Monte Carlo algorithms, which ...
  • Polyakov, Yuriy S.; Timashev, Serge F.; Neilsen, Joseph M. G. (IOP Publishing, 2012-05)
    We examine stochastic variability in the dynamics of X-ray emission from the black hole system GRS 1915+105, a strongly variable microquasar commonly used for studying relativistic jets and the physics of black hole ...
  • Lu, Ye; Simchi-Levi, David; Ozdaglar, Asuman E. (Elsevier, 2010-11)
    We consider the problem of stock repurchase over a finite time horizon. We assume that a firm has a reservation price for the stock, which is the highest price that the firm is willing to pay to repurchase its own stock. ...
