  • Gershman, Samuel J. (MIT Press, 2014-02)
    Temporal difference learning models of dopamine assert that phasic levels of dopamine encode a reward prediction error. However, this hypothesis has been challenged by recent observations of gradually ramping stratal ...
  • Maison, Stephane F.; Liu, Xiao-Ping; Eatock, Ruth Anne; Sibley, David R.; Grandy, David K.; Liberman, M. Charles (Society for Neuroscience, 2012-01)
    Pharmacological studies suggest that dopamine release from lateral olivocochlear efferent neurons suppresses spontaneous and sound-evoked activity in cochlear nerve fibers and helps control noise-induced excitotoxicity; ...
  • Omura, Daniel T.; Clark, Damon A.; Samuel, Aravinthan D. T.; Horvitz, H. Robert (Public Library of Science, 2012-06)
    Dopamine is an important neuromodulator in both vertebrates and invertebrates. We have found that reduced dopamine signaling can cause a distinct abnormality in the behavior of the nematode C. elegans, which has only eight ...
  • Hong, Yeonjun Simon (Frontiers Research Foundation, 2013-12)
    There are a growing number of roles that midbrain dopamine (DA) neurons assume, such as, reward, aversion, alerting and vigor. Here I propose a theory that may be able to explain why the suggested functions of DA came ...
  • Ko, Wing Ho; Lee, Patrick A.; Wen, Xiao-Gang (American Physical Society, 2009-06)
    A Chern-Simons theory for the doped spin-1/2 kagome system is constructed, from which it is shown that the system is an exotic superconductor that breaks time-reversal symmetry. It is also shown that the system carries ...
  • Yang, Ming; Yildiz, Bilge; Youssef, Mostafa Youssef Mahmoud (American Physical Society, 2016-01)
    Hydrogen pickup and embrittlement pose a challenging safety limit for structural alloys used in a wide range of infrastructure applications, including zirconium alloys in nuclear reactors. Previous experimental observations ...
  • Dublon, Gershon; Swartz, Noah; Joliat, Nicholas; Paradiso, Joseph A.; Pardue, Laurel Smith; Mayton, Brian Dean; Hurst, Patrick M. (Institute of Electrical and Electronics Engineers (IEEE), 2011-10)
    We present DoppelLab, an immersive sensor data browser built on a 3-d game engine. DoppelLab unifies independent sensor networks and data sources within the spatial framework of a building. Animated visualizations and ...
  • Dai, Fei; Arriagada, Pamela; Butler, R. Paul; Crane, Jeffrey D.; Johnson, John Asher; Shectman, Stephen A.; Teske, Johanna K.; Thompson, Ian B.; Vanderburg, Andrew; Wittenmyer, Robert A.; Winn, Joshua Nathan (IOP Publishing, 2015-10)
    We present precise Doppler observations of WASP-47, a transiting planetary system featuring a hot Jupiter with both inner and outer planetary companions. This system has an unusual architecture and also provides a rare ...
  • Hong, Stanley S.; Freeman, Dennis M. (SPIE, 2006-10)
    The possibility of measuring subnanometer motions with micron scale spatial resolution in the intact mammalian cochlea using Doppler optical coherence microscopy (DOCM) is demonstrated. A novel DOCM system is described ...
  • Showman, Adam P.; Fortney, Jonathan J.; Lewis, Nikole; Shabram, Megan (IOP Publishing, 2012-12)
    The meteorology of hot Jupiters has been characterized primarily with thermal measurements, but recent observations suggest the possibility of directly detecting the winds by observing the Doppler shift of spectral lines ...
  • Drexler, Alejandro; Schoar, Antoinette (Institute for Operations Research and the Management Sciences (INFORMS), 2014-08)
    We show that the cost of employee turnover in firms that rely on decentralized knowledge and personal relationships depends on the firms' planning horizons and the departing employees' incentives to transfer information. ...
  • Wells, Alan; Griffith, Linda G.; Wells, Jakob Z.; Taylor, Donald P. (American Association for Cancer Research, 2013-06)
    Metastatic dissemination with subsequent clinical outgrowth leads to the greatest part of morbidity and mortality from most solid tumors. Even more daunting is that many of these metastatic deposits silently lie undetected, ...
  • Matthews, Gillian A.; Nieh, Edward H.; Vander Weele, Caitlin M.; Halbert, Sarah A.; Pradhan, Roma V.; Yosafat, Ariella S.; Glober, Gordon F.; Izadmehr, Ehsan M.; Thomas, Rain E.; Lacy, Gabrielle D.; Wildes, Craig P.; Ungless, Mark A.; Tye, Kay M.; Matthews, Gillian A.; Nieh, Edward H.; Vander Weele, Caitlin M.; Halbert, Sarah A.; Pradhan, Roma V.; Yosafat, Ariella S.; Glober, Gordon F.; Izadmehr, Ehsan M.; Thomas, Rain E.; Lacy, Gabrielle D.; Wildes, Craig P.; Tye, Kay M. (Cell Press/Elsevier, 2016-02)
    The motivation to seek social contact may arise from either positive or negative emotional states, as social interaction can be rewarding and social isolation can be aversive. While ventral tegmental area (VTA) dopamine ...
  • Bidle, Kay D.; Van Mooy, Benjamin A. S.; Edwards, Bethanie Rachele (National Academy of Sciences (U.S.), 2015-05)
    Diatoms and other phytoplankton play a crucial role in the global carbon cycle, fixing CO[subscript 2] into organic carbon, which may then be exported to depth via sinking particles. The molecular diversity of this organic ...
  • Mukherjee, Sayan; Yurkovetsky, Zoya; Clyde, Merlise; Marks, Jeffrey R.; Lokshin, Anna E.; Lo, Joseph Y.; Jesneck, Jonathan Lee (Springer (Biomed Central Ltd.), 2009-05)
    Background Because screening mammography for breast cancer is less effective for premenopausal women, we investigated the feasibility of a diagnostic blood test using serum proteins. Methods This study used a set ...
  • Groß, Andrea; Kremling, Michael; Marr, Isabella; Kubinski, David; Visser, Jacobus; Moos, Ralf; Tuller, Harry L. (MDPI AG, 2013-04)
    An impedimetric NO[subscript x] dosimeter based on the NO[subscript x] sorption material KMnO[subscript 4] is proposed. In addition to its application as a low level NO[subscript x] dosimeter, KMnO[subscript 4] shows ...
  • Edrissi, Bahar; Taghizadeh, Koli; Moeller, Benjamin C.; Kracko, Dean; Doyle-Eisele, Melanie; Swenberg, James A.; Dedon, Peter C. (American Chemical Society (ACS), 2013-10)
    With formaldehyde as the major source of endogenous N[superscript 6]-formyllysine protein adducts, we quantified endogenous and exogenous N[superscript 6]-formyllysine in the nasal epithelium of rats exposed by inhalation ...
  • Gruber, Jonathan; Kleiner, Samuel A. (American Economic Association, 2012-02)
    Hospitals now represent one of the largest union sectors of the US economy, and there is particular concern about the impact of strikes on patient welfare. We analyze the effects of nurses' strikes in hospitals on patient ...
  • Olken, Benjamin A. (American Economic Association, 2009-10)
    This paper investigates the impact of television and radio on social capital in Indonesia. I use two sources of variation in signal reception -- one based on Indonesia's mountainous terrain, and a second based on the ...
  • Autor, David H.; Houseman, Susan N. (American Economic Association, 2010-07)
    Temporary-help jobs offer rapid entry into paid employment, but they are typically brief and it is unknown whether they foster longer term employment. We utilize the unique structure of Detroit's welfare-to- work program ...
