  • Live birth in an archosauromorph reptile 

    Liu, Jun; Organ, Chris L.; Benton, Michael J.; Brandley, Matthew C.; Aitchison, Jonathan C. (2017-02)
    Live birth has evolved many times independently in vertebrates, such as mammals and diverse groups of lizards and snakes. However, live birth is unknown in the major clade Archosauromorpha, a group that first evolved some ...
  • The effects of interleukin-2 on immune response regulation 

    Waters, Ryan S.; Perry, Justin S. A.; Han, SunPil; Bielekova, Bibiana; Gedeon, Tomáš (2017-02)
    The immune system has many adaptive and dynamic components that are regulated to ensure appropriate, precise and rapid response to a foreign pathogen. A delayed or inadequate immune response can lead to prolonged disease, ...
  • Analytic Gravitational Waveforms for Generic Precessing Binary Inspirals 

    Chatziioannou, Katerina; Klein, Antoine; Cornish, Neil J.; Yunes, Nicolas (2017-02)
    Binary systems of two compact objects circularize and spiral toward each other via the emission of gravitational waves. The coupling of the spins of each object with the orbital angular momentum causes the orbital plane ...
  • Revisiting the determinants of futures contracts success: the role of market participants 

    Bekkerman, Anton; Tejeda, Hernan A. (2017-03)
    The Chicago Mercantile Exchange introduced a futures contract for distillers' dried grains (DDGs) in early 2010, but the market became inactive only four months after its inception. While many new futures contracts do not ...
  • Global Dynamics for Steep Nonlinearities in Two Dimensions 

    Gedeon, Tomáš; Harker, Shaun; Kokubu, Hiroshi; Mischaikow, Konstanin; Oka, Hiroe (2017-01)
    This paper discusses a novel approach to obtaining mathematically rigorous results on the global dynamics of ordinary differential equations. We study switching models of regulatory networks. To each switching network we ...
  • Booster Seat Effectiveness Among Older Children: Evidence From Washington State 

    Anderson, D. Mark; Carlson, Lindsay L.; Rees, Daniel I. (2017-08)
    Introduction The American Academy of Pediatrics has recommended that children as old as 12 years use a booster seat when riding in motor vehicles, yet little is known about booster seat effectiveness when used by older ...
  • Pinus contorta invasions increase wildfire fuel loads and may create a positive feedback with fire 

    Taylor, Kimberly T.; Maxwell, Bruce D.; McWethy, David B.; Pauchard, Anibal; Nunez, Martin A.; Whitlock, Cathy (2017-03)
    Invasive plant species that have the potential to alter fire regimes have significant impacts on native ecosystems. Concern that pine invasions in the Southern Hemisphere will increase fire activity and severity and ...
  • Differential regulation of CD103 (alphaE integrin) expression in human dendritic cells by retinoic acid and Toll-like receptor ligands 

    Roe, Mandi M.; Swain, Steve; Sebrell, T. Andrew; Sewell, Maris A.; Collins, Madison M.; Perrino, Brian A.; Smith, Phillip D.; Smythies, Lesley E.; Bimczok, Diane (2017-05)
    CD103 (alphaE integrin) is an important dendritic cell (DC) marker that characterizes functionally distinct DC subsets in mice and humans. However, the mechanism by which CD103 expression is regulated in human DCs and the ...
  • Effect of salinity on mercury methylating benthic microbes and their activities in Great Salt Lake, Utah 

    Boyd, Eric S.; Yu, Ri-Qing; Barkay, Tamar; Hamilton, Trinity L.; Baxter, Bonnie K.; Naftz, David L.; Marvin-DiPasquale, Mark (2017-03)
    Surface water and biota from Great Salt Lake (GSL) contain some of the highest documented concentrations of total mercury (THg) and methylmercury (MeHg) in the United States. In order to identify potential biological sources ...
  • Over Expression of NANOS3 and DAZL in Human Embryonic Stem Cells 

    Panula, Sarita; Reda, Ahmed; Stukenborg, Jan-Bernd; Ramathal, Cyril; Sukhwani, Meena; Albalushi, Halima; Edsgard, Daniel; Nakamura, Michiko; Soder, Olle; Orwig, Kyle E.; Yamanaka, Shinya; Reijo Pera, Renne A. (2016-10)
    The mechanisms underlying human germ cell development are largely unknown, partly due to the scarcity of primordial germ cells and the inaccessibility of the human germline to genetic analysis. Human embryonic stem cells ...
  • Approximate universal relations among tidal parameters for neutron star binaries 

    Yagi, Kent; Yunes, Nicolas (2017-01)
    One of the largest uncertainties in nuclear physics is the relation between the pressure and density of supranuclear matter: the equation of state. Some of this uncertainty may be removed through future gravitational wave ...
  • A Detection Probability Model for Aerial Surveys of Mule Deer 

    Zabransky, Cody J.; Hewitt, David G.; Deyoung, Randy W.; Gray, Shawn S.; Richardson, Calvin; Litt, Andrea R.; Deyoung, Charles A. (2016-11)
    Population estimates derived from aerial surveys of ungulates are biased by imperfect detection, where probability of sighting groups is influenced by variables specific to terrain features and vegetation communities. ...
  • The Quantum Biology of Reactive Oxygen Species Partitioning Impacts Cellular Bioenergetics 

    Usselman, Robert J.; Chavarriaga, Cristina; Castello, Pablo R.; Procopio, Maria; Ritz, Thorsten; Dratz, Edward A.; Singel, David J.; Martino, Carlos F. (2016-12)

  • Climate driven thresholds for chemical weathering in post-glacial soils of New Zealand 

    Dixon, Jean L.; Chadwick, Oliver A.; Vitousek, Peter (2016-09)
