      The isostatic jamming limit of frictionless spherical particles from Edwards' statistical mechanics [Song et al., Nature (London) 453, 629 (2008)] is generalized to arbitrary dimension d using a liquid-state description. ...
    • Can prospect theory explain risk-seeking behavior by terminally ill patients? 

      Rasiel, Emma B; Weinfurt, Kevin P; Schulman, Kevin A (Med Decis Making, 2005-11)
      Patients with life-threatening conditions sometimes appear to make risky treatment decisions as their condition declines, contradicting the risk-averse behavior predicted by expected utility theory. Prospect theory accommodates ...
    • Characterizing the Switching Thresholds of Magnetophoretic Transistors. 

      Abedini-Nassab, Roozbeh; Joh, Daniel Y; Van Heest, Melissa A; Yi, John S; Baker, Cody; Taherifard, Zohreh; Margolis, David M; ... (11 authors) (Adv Mater, 2015-10-28)
      The switching thresholds of magnetophoretic transistors for sorting cells in microfluidic environments are characterized. The transistor operating conditions require short 20-30 mA pulses of electrical current. By demonstrating ...
    • Climate adaptation and policy-induced inflation of coastal property value. 

      McNamara, Dylan E; Gopalakrishnan, Sathya; Smith, Martin D; Murray, A Brad (PLoS One, 2015)
      Human population density in the coastal zone and potential impacts of climate change underscore a growing conflict between coastal development and an encroaching shoreline. Rising sea-levels and increased storminess threaten ...
    • Comparing the model-simulated global warming signal to observations using empirical estimates of unforced noise. 

      ◦Brown, P.T., W. Li, E.C. Cordero, S.A. Mauget (Sci Rep, 2015-04-21)
      The comparison of observed global mean surface air temperature (GMT) change to the mean change simulated by climate models has received much public and scientific attention. For a given global warming signal produced by ...
    • Complex k band diagrams of 3D metamaterial/photonic crystals. 

      Fietz, Chris; Urzhumov, Yaroslav; Shvets, Gennady (Opt Express, 2011-09-26)
      A finite element method (FEM) for solving a complex valued k(ω) vs. ω dispersion curve of a 3D metamaterial/photonic crystal system is presented. This 3D method is a generalization of a previously reported 2D eigenvalue ...
    • Cost of capital to the hospital sector. 

      Sloan, FA; Valvona, J; Hassan, M; Morrisey, MA (J Health Econ, 1988-03)
      This paper provides estimates of the cost of equity and debt capital to for-profit and non-profit hospitals in the U.S. for the years 1972-83. The cost of equity is estimated using, alternatively, the Capital Asset Pricing ...
    • Cumulative early life adversity predicts longevity in wild baboons. 

      Tung, J; Archie, EA; Altmann, J; Alberts, SC (Nat Commun, 2016-04-19)
      In humans and other animals, harsh circumstances in early life predict morbidity and mortality in adulthood. Multiple adverse conditions are thought to be especially toxic, but this hypothesis has rarely been tested in a ...
