  • Belloni, Alexandre; Freund, Robert Michael (Springer Berlin, 2008-01)
    For a conic linear system of the form Ax ∈ K, K a convex cone, several condition measures have been extensively studied in the last dozen years.Among these, Renegar’s condition number C(A) is arguably the most prominent ...
  • Modiano, Eytan H.; Chen, Li-Wei (Springer, 2009)
    In this chapter, we use an asymptotic analysis similar to the spherepacking argument in the proof of Shannon’s channel capacity theorem to derive optimal provisioning requirements for networks with both static and dynamic ...
  • Bertsimas, Dimitris J.; Goyal, Vineet; Sun, Xu Andy (Institute for Operations Research and the Management Sciences (INFORMS), 2011-02)
    In this paper, we show a significant role that geometric properties of uncertainty sets, such as symmetry, play in determining the power of robust and finitely adaptable solutions in multistage stochastic and adaptive ...
  • Anderson, Lara B.; Taylor, Washington (Springer-Verlag, 2014-08)
    We systematically analyze a broad class of dual heterotic and F-theory models that give four-dimensional supergravity theories, and compare the geometric constraints on the two sides of the duality. Specifically, we give ...
  • Baranski, Jan D.; Chaturvedi, Ritika R.; Stevens, Kelly R.; Eyckmans, Jeroen; Carvalho, Brian; Solorzano, Ricardo D.; Yang, Michael T.; Miller, Jordan S.; Bhatia, Sangeeta N.; Chen, Christopher S. (National Academy of Sciences (U.S.), 2013-05)
    Tissue vascularization and integration with host circulation remains a key barrier to the translation of engineered tissues into clinically relevant therapies. Here, we used a microtissue molding approach to demonstrate ...
  • Lalley, Steven P.; Lawler, Gregory F.; Narayanan, Hariharan (Institute of Mathematical Statistics, 2009-12)
    Schramm-Loewner Evolution describes the scaling limits of interfaces in certain statistical mechanical systems. These interfaces are geometric objects that are not equipped with a canonical parametrization. The standard ...
  • Bousso, Raphael; Leichenauer, Stefan; Rosenhaus, Vladimir; Freivogel, Benjamin W. (American Physical Society (APS), 2011-10)
    We show that the geometry of cutoffs on eternal inflation strongly constrains predictions for the time scales of vacuum domination, curvature domination, and observation. We consider three measure proposals: the causal ...
  • Swingle, Brian Gordon; Todadri, Senthil (American Physical Society, 2012-07)
    The bulk-edge correspondence for topological quantum liquids states that the spectrum of the reduced density matrix of a large subregion reproduces the thermal state of a physical edge. This correspondence suggests an ...
  • Teo, Justin; How, Jonathan P. (Institute of Electrical and Electronics Engineers, 2010-07)
    The gradient projection anti-windup (GPAW) scheme was recently proposed as an anti-windup method for nonlinear multi-input-multi-output systems/controllers, which was recognized as a largely open problem in a recent survey ...
  • Bousso, Raphael; Freivogel, Benjamin W.; Leichenauer, Stefan; Rosenhaus, Vladimir (American Physical Society, 2011-03)
    Weinberg’s seminal prediction of the cosmological constant relied on a provisional method for regulating eternal inflation which has since been put aside. We show that a modern regulator, the causal patch, improves agreement ...
  • Pak, Igor; Konvalinka, Matjaz (Elsevier, 2008-09)
    In this paper we analyze O'Hara's partition bijection. We present three type of results. First, we show that O'Hara's bijection can be viewed geometrically as a certain scissor congruence type result. Second, we obtain a ...
  • Lee, Wei Li; Low, Hong Yee (Springer Nature, 2016-03)
    Micro- and nanoscale surface textures, when optimally designed, present a unique approach to improve surface functionalities. Coupling surface texture with shape memory polymers may generate reversibly tuneable surface ...
  • Lauga, Eric; Peraud, Jean-Philippe Michel (American Physical Society, 2014-04)
    Capillary forces are involved in a variety of natural phenomena, ranging from droplet breakup to the physics of clouds. The forces from surface tension can also be exploited in industrial applications provided the length ...
  • Clem, John R.; Berggren, Karl K. (American Physical Society, 2011-11)
    In this paper, we calculate the critical currents in thin superconducting strips with sharp right-angle turns, 180∘ turnarounds, and more complicated geometries, where all the line widths are much smaller than the Pearl ...
  • Moser, H. O.; Jian, L. K.; Kalaiselvi, S. M. P.; Virasawmy, S.; Cheng, X. X.; Banas, A.; Banas, K.; Heussler, S. P.; Bahou, M.; Chen, H. S.; Wu, Bae-Ian; Hua, Wei; Yi, Zhu (SPIE, 2010-04)
    Meta-foils are all-metal free-standing electromagnetic metamaterials based on interconnected S-string architecture. They provide a versatile applications' platform. Lacking any substrate or embedding matrix, they feature ...
  • Rodriguez, Alejandro W.; Reid, M. T. Homer; Intravaia, Francesco; Woolf, Alexander; Dalvit, D. A. R.; Capasso, Federico; Johnson, Steven G. (American Physical Society, 2013-10)
    We predict that a low-permittivity oblate body (disk-shaped object) above a thin metal substrate (plate with a hole) immersed in a fluid of intermediate permittivity will experience a metastable equilibrium (restoring ...
  • Lazarus, Arnaud; Florijn, H. C. B.; Reis, Pedro Miguel (American Physical Society, 2012-10)
    We present results from an experimental investigation of the indentation of nonspherical pressurized elastic shells with a positive Gauss curvature. A predictive framework is proposed that rationalizes the dependence of ...
  • Petroff, A. P.; Devauchelle, Olivier; Abrams, D. M.; Lobkovsky, Alexander E.; Kudrolli, Arshad; Rothman, Daniel H. (Cambridge University Press, 2011-03)
    Although amphitheatre-shaped valley heads can be cut by groundwater flows emerging from springs, recent geological evidence suggests that other processes may also produce similar features, thus confounding the interpretations ...
  • Jifeng, Liu; Michel, Jurgen; Kimerling, Lionel C. (Institute of Electrical and Electronics Engineers (IEEE), 2010-11)
    We review recent progress in Ge active photonic devices for electronic-photonic integration on Si, demonstrating new tricks in optoelectronics from this “old” semiconductor material used for the first transistor more than ...
  • Sun, Xiaochen; Liu, Jifeng; Kimerling, Lionel C.; Michel, Jurgen (Institute of Electrical and Electronics Engineers, 2009-08)
    We demonstrate room temperature photoluminescence and optical gain from the direct band gap transition of tensile strained n-type Ge-on-Si around 1600 nm, which can be applied to a Si-based laser for optical interconnects ...
