  • Lienhard, John H.; Thiel, Gregory Parker (Elsevier, 2012-05)
    The physical mechanisms of entropy generation in a condenser with high fractions of noncondensable gases are examined using scaling and boundary layer techniques, with the aim of defining a criterion for minimum entropy ...
  • Lienhard, John H.; Zubair, Syed M.; Narayan, G. Prakash (Elsevier, 2010-06)
    This paper details a simple procedure by which the entropy generation in simultaneous heat and mass exchange devices can be minimized. Effectiveness for these devices is defined and a new parameter, ‘modified heat capacity ...
  • Mistry, Karan Hemant; Chung, Hyung; Warsinger, David Elan Martin; Nayar, Kishor Govind; Lienhard, John H.; Chung, Hyung Won (MDPI AG, 2015-10)
    Powering desalination by waste heat is often proposed to mitigate energy consumption and environmental impact; however, thorough technology comparisons are lacking in the literature. This work numerically models the ...
  • Yu, Yun William; Daniels, Noah; Danko, David C.; Berger Leighton, Bonnie (Elsevier, 2015-08)
    Many datasets exhibit a well-defined structure that can be exploited to design faster search tools, but it is not always clear when such acceleration is possible. Here, we introduce a framework for similarity search based ...
  • Buzard, James (Penn State University Press, 2008)
    The Old Curiosity Shop marks a crisis in Dickens’s early career. Overcommitted to projects, a victim of his own success, Dickens soon found his episodic model of fiction, first practiced in Pickwick and devoted to furnishing ...
  • Moon, SangJun; Gurkan, Umut Atakan; Blander, Jeffrey; Fawzi, Wafaie W.; Aboud, Said; Mugusi, Ferdinand; Kuritzkes, Daniel R.; Demirci, Utkan (Public Library of Science, 2011-04)
    Background CD4+ T-lymphocyte count (CD4 count) is a standard method used to monitor HIV-infected patients during anti-retroviral therapy (ART). The World Health Organization (WHO) has pointed out or recommended that a ...
  • Pisania, Anna; Papas, Klearchos K.; Powers, Daryl E.; Rappel, Michael J.; Omer, Abdulkadir; Bonner-Weir, Susan; Weir, Gordon C.; Colton, Clark K. (Nature Publishing Group, 2010-08)
    Islet enumeration in impure preparations by conventional dithizone staining and visual counting is inaccurate and operator dependent. We examined nuclei counting for measuring the total number of cells in islet preparations, ...
  • Cantine, Marjorie Dianne; Fournier, Gregory P. (Springer Netherlands, 2017-07)
    Extensive fundamental molecular and biological evolution took place between the prebiotic origins of life and the state of the Last Universal Common Ancestor (LUCA). Considering the evolutionary innovations between these ...
  • Cooper, Daniel R.; Rossie, Kathleen Eaton; Gutowski, Timothy G (American Society of Mechanical Engineers (ASME), 2016-07)
    Little work has been done on quantifying the environmental impacts and costs of sheet metal stamping. In this work we present models that can be used to predict the energy requirements, global warming potential, human ...
  • Cooper, Daniel A; Rossie, Kathleen Eaton; Gutowski, Timothy G (ASME International, 2016-11)
    Little work has been done on quantifying the environmental impacts and costs of sheet metal stamping. In this work, we present models that can be used to predict the energy requirements, global warming potential, human ...
  • Langdon, C.; Hughen, K. A.; McCorkle, D. C.; Lentz, S. J.; Bernstein, Whitney Nicole (Springer Berlin Heidelberg, 2016-01)
    Coral growth and carbonate accumulation form the foundation of the coral reef ecosystem. Changes in environmental conditions due to coastal development, climate change, and ocean acidification may pose a threat to net ...
  • Lewis, Caroline A; Muir, Alexander; Danai, Laura V; Gui, Dan Yi; Waingarten, Chiara Y.; Vander Heiden, Matthew G. (eLife Sciences Publications, Ltd, 2017-08)
    Many mammalian cancer cell lines depend on glutamine as a major tri-carboxylic acid (TCA) cycle anaplerotic substrate to support proliferation. However, some cell lines that depend on glutamine anaplerosis in culture rely ...
  • Kemp, Ronald S. (Annual Reviews, 2016-01)
    Environmental sensing of nuclear activities has the potential to detect nuclear weapon programs at early stages, deter nuclear proliferation, and help verify nuclear accords. However, no robust system of detection has been ...
  • Endo, Noriko; Eltahir, Elfatih A. B. (BioMed Central, 2016-12)
    Background Malaria transmission is complex, involving a range of hydroclimatological, biological, and environmental processes. The high degree of non-linearity in these processes makes it difficult to predict and intervene ...
  • Chiu, C. S.; Ignarra, Christina; Bugel, Leonard G.; Chen, H.; Conrad, Janet; Jones, Benjamin James Poyner; Katori, Teppei; Moult, Ian James (Institute of Physics Publishing, 2012-07)
    The scintillation detection systems of liquid argon time projection chambers (LArTPCs) require wavelength shifters to detect the 128 nm scintillation light produced in liquid argon. Tetraphenyl butadiene (TPB) is a fluorescent ...
  • Brooks, Zanzile; Ulm, Franz-Josef; Einstein, Herbert H. (Springer-Verlag, 2013-03)
    This study explores the interaction between crack initiation and nanomechanical properties in the crack-tip fracture process zone of Carrara marble. Specimens with preexisting cracks were loaded in a uniaxial testing machine ...
  • Acemoglu, Daron; Aghion, Philippe; Bursztyn, Leonardo; Hemous, David (American Economic Association, 2012-02)
    This paper introduces endogenous and directed technical change in a growth model with environmental constraints. A unique final good is produced by combining inputs from two sectors. One of these sectors uses “dirty” ...
  • Cappellaro, Paola; Hodges, Jonathan S.; Goldstein, Garry; Jiang, Liang; Maze, Jeronimo R.; Sørensen, A. S.; Lukin, Mikhail D. (American Physical Society, 2012-03)
    We investigate the sensitivity of a recently proposed method for precision measurement [ Phys. Rev. Lett. 106 140502 (2011)], focusing on an implementation based on solid-state spin systems. The scheme amplifies a quantum ...
  • Goldstein, Garry; Cappellaro, Paola; Maze, Jeronimo R.; Hodges, Jonathan S.; Jiang, L.; Sorensen, A. S.; Lukin, M. D. (American Physical Society, 2011-04)
    We describe a method to enhance the sensitivity of precision measurements that takes advantage of the environment of a quantum sensor to amplify the response of the sensor to weak external perturbations. An individual qubit ...
  • Rebentrost, Patrick; Mohseni, Masoud; Kassal, Ivan; Lloyd, Seth; Aspuru-Guzik, Alan (Institute of Physics Publishing, 2009-03)
    Transport phenomena at the nanoscale are of interest due to the presence of both quantum and classical behavior. In this work, we demonstrate that quantum transport efficiency can be enhanced by a dynamical interplay of ...
