  • Win, Moe Z.; Rabbachin, Alberto; Quek, Tony Q. S.; Oppermann, Ian (Institute of Electrical and Electronics Engineers, 2009-10)
    Over the last few years there has been an emerging interest in ultrawideband (UWB) communications in wireless sensor networks, mainly due to their low-complexity and low-power consumption. In particular, auto-correlation ...
  • Rabbachin, Alberto; Quek, Tony Q. S.; Oppermann, Ian; Win, Moe Z. (Institute of Electrical and Electronics Engineers, 2009-06)
    Over the last few years, there has been an emerging interest in applying ultrawideband (UWB) communications in wireless sensor networks, mainly due to the low-complexity and low-power consumption of UWB technology. In ...
  • Emanuel, Kerry Andrew (American Meteorological Society, 2015-10)
    Recent work has highlighted the possible importance of changing upper-ocean thermal and density stratification on observed and projected changes in tropical cyclone activity. Here seven CMIP phase 5 (CMIP5)-generation ...
  • Poliannikov, Oleg V.; Malcolm, Alison E. (Society of Exploration Geophysicists, 2015-11)
    We have studied the problem of uncertainty quantification for migrated images. A traditional migrated image contains deterministic reconstructions of subsurface structures. However, input parameters used in migration, such ...
  • McGovern, Ronan Killian; McConnon, Dillon; Lienhard, John H. (International Desalination Association, 2015-08)
    We employ a stirred-cell reverse osmosis setup to demonstrate that a seawater reverse osmosis membrane can maintain excellent salt rejection at pressures as high as 172 bar. However, we also demonstrate a very significant ...
  • Wall, Conrad; Sienko, Kathleen H.; Balkwill, M. David; Oddsson, Lars I. E. (BioMed Central Ltd, 2013-08)
    Background: Although significant progress has been achieved in developing sensory augmentation methods to improve standing balance, attempts to extend this research to locomotion have been quite limited in scope. The goal ...
  • Prates, Renato A.; Burgwyn Fuchs, Beth; Mizuno, Kazue; Naqvi, Qurat; Kato, Ilka T.; Ribeiro, Martha S.; Mylonakis, Eleftherios; Tegos, George P.; Hamblin, Michael R. (Public Library of Science, 2013-01)
    Opportunistic fungal pathogens may cause an array of superficial infections or serious invasive infections, especially in immunocompromised patients. Cryptococcus neoformans is a pathogen causing cryptococcosis in HIV/AIDS ...
  • Chen, Aaron Chih-Hao; Huang, Ying-Ying; Sharma, Sulbha K.; Hamblin, Michael R. (Mary Ann Liebert, Inc., 2011-06)
    Objective: The purpose of this study was to Investigate the effect of 810-nm low level laser therapy (LLLT) on dendritic cells (DC) in vitro. Background data: LLLT can enhance wound healing and increase cell proliferation ...
  • Rominger, Jeffrey Tsaros; Lightbody, Anne; Nepf, Heidi (American Society of Civil Engineers, 2010-02)
    Vegetation was added to a fully developed sandy point bar in the meander of a constructed stream. Significant changes in the flow structure and bed topography were observed. As expected, the addition of vegetative resistance ...
  • Boselli, Monica; Rock, Jeremy Michael; Unal, Elcin; Levine, Stuart S.; Amon, Angelika B. (Elsevier, 2009-06)
    In humans, the frequency with which meiotic chromosome mis-segregation occurs increases with age. Whether age-dependent meiotic defects occur in other organisms is unknown. Here, we examine the effects of replicative aging ...
  • Sung, Kyung Rim; Wollstein, Gadi; Bilonick, Richard A.; Townsend, Kelly A.; Ishikawa, Hiroshi; Kagemann, Larry; Noecker, Robert J.; Fujimoto, James G.; Schuman, Joel S. (Elsevier, 2009-06)
    Purpose—To determine the effects of age on global and sectoral peripapillary retinal nerve fiber layer (RNFL), macular thicknesses and optic nerve head (ONH) parameters in healthy subjects using optical coherence tomography ...
  • Tammela, Tuomas; Holopainen, Tanja; Saharinen, Pipsa; D’Amico, Gabriela; Lampinen, Anita; Eklund, Lauri; Sormunen, Raija; Anisimov, Andrey; Zarkada, Georgia; Lohela, Marja; Heloterä, Hanna; Benjamin, Laura E.; Ylä-Herttuala, Seppo; Leow, Ching Ching; Koh, Gou Young; Alitalo, Kari (Oxford University Press (OUP), 2012-02)
    Background: Angiopoietin-2 (Ang2), a ligand for endothelial TEK (Tie2) tyrosine kinase receptor, is induced in hypoxic endothelial cells of tumors, where it promotes tumor angiogenesis and growth. However, the effects of ...
  • Vosoughi, Soroush; Roy, Brandon Cain; Frank, Michael C.; Roy, Deb K. (Speech Prosody Special Interest Group (SProSIG) of the International Speech Communication Association (ISCA), 2010-05)
    This paper investigates the role of prosody in one child’s lexical acquisition using an ecologically valid, high-density, longitudinal corpus. The corpus consists of high fidelity recordings collected from microphones ...
  • Cheng, Wai K.; Wildman, Craig B. (SAE International, 2010-04)
    The effects of charge motion and laminar flame speeds on combustion and exhaust temperature have been studied by using an air jet in the intake flow to produce an adjustable swirl or tumble motion, and by replacing the ...
  • Bhalla, Gaurav; Deen, William M. (Elsevier, 2009-09)
    A model based on continuum hydrodynamics and electrostatics was developed to predict the combined effects of molecular charge and size on the osmotic reflection coefficient (σ[subscript o]) of a macromolecule in a fibrous ...
  • Sanglimsuwan, Apiradee; Seeponkai, Narumon; Wootthikanokkhan, Jatuphorn (SAGE-Hindawi Access to Research, 2011-04)
    Electrolyte nanocomposite membranes for proton exchange membrane fuel cells and direct methanol fuel cells were prepared by carrying out a sulfonation of poly(vinyl alcohol) with sulfosuccinic acid and adding a type of ...

    In the observation of multiple thresholds in the cavity-quantum electrodynamics microlaser there was deviation from the result predicted by uniform atom-cavity coupling theory, notably a frequency-pushing behavior. We ...
  • Brown, Emery N.; Sarma, Sridevi V.; Cheng, Ming L.; Eden, Uri T.; Williams, Ziv; Eskandar, Emad (Frontiers Research Foundation, 2012-07)
    Visual cues open a unique window to the understanding of Parkinson's disease (PD). These cues can temporarily but dramatically improve PD motor symptoms. Although details are unclear, cues are believed to suppress pathological ...
