  • Gitty, Anthony; Braunstein, Alfredo; Pagnani, Andrea; Baldassi, Carlo; Borgs, Christian; Chayes, Jennifer; Zecchina, Riccardo; Fraenkel, Ernest; Gitter, Anthony (World Scientific Publishing, 2014-01)
    Advances in experimental techniques resulted in abundant genomic, transcriptomic, epigenomic, and proteomic data that have the potential to reveal critical drivers of human diseases. Complementary algorithmic developments ...
  • Schulz, Andreas S.; Uhan, Nelson A. (INFORMS, 2010-07)
    We study cooperative games with supermodular costs. We show that supermodular costs arise in a variety of situations; in particular, we show that the problem of minimizing a linear function over a supermodular polyhedron—a ...
  • Frazzoli, Emilio; Pavone, Marco; Savla, Ketan (Institute of Electrical and Electronics Engineers, 2009-06)
    In this article, we discussed the use of various spatial tessellations to determine, in the framework of partitioning policies, optimal workload share in a mobile robotic network. We also proposed efficient and spatially ...
  • Kanhere, E.; Triantafyllou, M.S.; Miao, J.M.; Wang, Nan (2015-06)
    Inspired by morphological structure of ciliated receptor cells, we design, fabricate and characterize a miniaturized MEMS (microelectromechanical systems) chemical sensor with micropillar electrode array, which mimics the ...
  • Gharibyan, Hrant; Tegmark, Max Erik (American Physical Society, 2014-09)
    We prove a generalization of the classic Groenewold-Lindblad entropy inequality, combining decoherence and the quantum Bayes theorem into a simple unified picture where decoherence increases entropy while observation ...
  • Colding, Tobias; Naber, Aaron Charles (Princeton University Press, 2012-09)
    We prove a new estimate on manifolds with a lower Ricci bound which asserts that the geometry of balls centered on a minimizing geodesic can change in at most a Holder continuous way along the geodesic. We give examples ...
  • Gilbertson, Eric W.; Freeman, Bryan; Hover, Franz S. (American Society of Mechanical Engineers, 2012-07)
    Gas-lifted oil wells are susceptible to failure through malfunction of gas lift valves (GLV). One failure mode occurs when the GLV check valve fails and product passes into the well annulus, potentially reaching the wellhead. ...
  • Du, Xiumin; Li, Xiaochun; Guth, Lawrence (Annals of Mathematics, Princeton U, 2017-08)
    We show that lim[subscript t→0] e[superscript itΔ]f(x) = f(x) almost everywhere for all f ∈ H[superscript s](R[superscript 2]) provided that s > 1/3. This result is sharp up to the endpoint. The proof uses polynomial ...
  • Haward, Simon J.; Sharma, Vivek; Butts, Craig P.; McKinley, Gareth H.; Rahatekar, Sameer S. (American Chemical Society, 2012-05)
    In this study, we characterize the shear and extensional rheology of dilute to semidilute solutions of cellulose in the ionic liquid 1-ethyl-3-methylimidazolium acetate (EMIAc). In steady shear flow, the semidilute solutions ...
  • Kwak, Rhokyun; Pham, Van Sang; Lim, Kian Meng; Han, Jongyoon (American Physical Society, 2013-03)
    We consider electroconvective fluid flows initiated by ion concentration polarization (ICP) under pressure-driven shear flow, a scenario often found in many electrochemical devices and systems. Combining scaling analysis, ...
  • Shatoff, Elan; Ramola, Kabir; Mari, Romain; Morris, Jeffrey; Chakraborty, Bulbul; Sarkar, Sumantra (EDP Sciences, 2017-06)
    Dense suspensions can exhibit an abrupt change in their viscosity in response to increasing shear rate. The origin of this discontinuous shear thickening (DST) has been ascribed to the transformation of lubricated contacts ...
  • Zhang, R. F.; Legut, D.; Niewa, R.; Argon, Ali Suphi; Veprek, S. (American Physical Society, 2010-09)
    The recent search for superhard materials concentrated on diborides of the 5d transition metals because of their high elastic moduli. Using density-functional theory we report a systematic study of the shear-induced ...
  • Gaharwar, Akhilesh K.; Assmann, Alexander; Paul, Arghya; McKinley, Gareth H.; Khademhosseini, Ali; Olsen, Bradley D.; Avery, Reginald Keith (American Chemical Society (ACS), 2014-09)
    Internal hemorrhaging is a leading cause of death after traumatic injury on the battlefield. Although several surgical approaches such as the use of fibrin glue and tissue adhesive have been commercialized to achieve ...
  • Li, L.; Homer, E. R.; Schuh, Christopher A. (Elsevier, 2013-03)
    A mesoscale model, shear transformation zone dynamics (STZ dynamics), is employed to investigate the connections between the structure and deformation of metallic glasses. The present STZ dynamics model is adapted to ...
  • Vernon, F.; Schaeffer, A.; Lebedev, S.; Golos, Eva Marie; Fang, Hongjian; Yao, Huajian; Zhang, Haijiang; Burdick, Scott Anthony; van der Hilst, Robert D (2018-06)
    Resolving both crustal and shallow-mantle heterogeneity, which is needed to study processes in and fluxes between crust and mantle, is still a challenge for seismic tomography. Body wave data can constrain deep features ...
  • Guldiken, Rasim; Jo, Myeong Chan; Gallant, Nathan D.; Zhe, Jiang; Demirci, Utkan (MDPI AG, 2012-01)
    Particle separation is of great interest in many biological and biomedical applications. Flow-based methods have been used to sort particles and cells. However, the main challenge with flow based particle separation systems ...
  • Brun, Pierre-Thomas; Harris, Daniel Martin; Prost, Victor; Quintela Casal, Julio; Bush, John W. M. (American Physical Society (APS), 2016-09)
    This paper is associated with a video winner of a 2015 APS/DFD Gallery of Fluid Motion Award. The original video is available from the Gallery of Fluid Motion, http://dx.doi.org/10.1103/APS.DFD.2015.GFM.V0064
  • Zhang, Yu; Pedlosky, Joseph; Flierl, Glenn Richard (American Meteorological Society, 2011-05)
    This paper examines interaction between a barotropic point vortex and a steplike topography with a bay-shaped shelf. The interaction is governed by two mechanisms: propagation of topographic Rossby waves and advection by ...

    Homomorphic encryption (HE) systems enable computations on encrypted data, without decrypting and without knowledge of the secret key. In this work, we describe an optimized Ring Learning With Errors (RLWE) based implementation ...
