      Bessonneau, Vincent; Pawliszyn, Janusz; Rappaport, Stephen M. (Environmental Health Perspectives - United States Federal Government, 2017-07-20)
      Background: There is increasing evidence that environmental, rather than genetic, factors are the major causes of most chronic diseases. By measuring entire classes of chemicals in archived biospecimens, exposome-wide ...
    • Sample size and robust marginal methods for cluster-randomized trials with censored event times 

      Cook, Richard J.; Zhong, Yujie (Wiley, 2015-03-15)
      In cluster-randomized trials, intervention effects are often formulated by specifying marginal models, fitting them under a working independence assumption, and using robust variance estimates to address the association ...

      Medeiros, Rafael Sachett; Wong, Alexander; Scharcanski, Jacob (Elsevier, 2018-06-01)
      Dealing with large images is an on-going challenge in image segmentation, where many of the current methods run into computational and/or memory complexity issues. This work presents a novel decoupled sub-graph compression ...
    • School start time changes in the COMPASS study: associations with youth sleep duration, physical activity, and screen time

      Background To date, no longitudinal population-based studies of school start times have been conducted within Canada. School schedule changes provided an opportunity to examine start times in association with youth sleep, ...
    • A Scoping Review of Frailty and Acute Care in Middle-Aged and Older Individuals with Recommendations for Future Research 

      Hogan, David B.; Maxwell, Colleen J.; Afilalo, Jonathan; Arora, Rakesh C.; Bagshaw, Sean; Basran, Jenny; Bergman, Howard; Bronskill, Susan; Carter, Caitlin A.; Dixon, Elijah; Hemmelgarn, Brenda; Madden, Kenneth; MITNITSKI, ARNOLD; Rolfson, Darryl; Stelfox, Henry; Tam-Tham, Helen; Wunsch, Hannah (Canadian Geriatrics Society, 2017-03-31)
      There is general agreement that frailty is a state of heightened vulnerability to stressors arising from impairments in multiple systems leading to declines in homeostatic reserve and resiliency, but unresolved issues ...
    • Score Tests for Association Under Response-dependent Sampling Designs for Expensive Covariates 

      Lawless, Jerald F. (Oxford Journals, 2015-11-27)
      Response-dependent sampling is widely used in settings where certain variables are expensive to obtain. Estimation has been thoroughly investigated but recent applications have emphasized tests of association for expensive ...
    • Searching for a DNAzyme version of the leadzyme 

      Saran, Runjhun; Chen, Qingyun; Liu, Juewen (Springer, 2015-10-12)
      The leadzyme refers to a small ribozyme that cleaves a RNA substrate in the presence of Pb2+. In an optimized form, the enzyme strand contains only two unpaired nucleotides. Most RNA-cleaving DNAzymes are much longer. Two ...
    • Searching for a perceived gaze direction using eye tracking 

      Itier, Roxane J.; Palancia, Adam (Association for Research in Visison and Ophthalmology, 2011-02-01)
      The purpose of the current study was to use eye tracking to better understand the “stare-in-the-crowd effect”—the notion that direct gaze is more easily detected than averted gaze in a crowd of opposite-gaze distractors. ...
    • Seeing Double at Memorial University: Two WorldCat Local Usability Studies 

      Fahey, Sue; Gordon, Shannon; Rose, Crystal (2011-05-01)
      Presentation slides as presented at the Atlantic Provinces Library Association (APLA) Conference, 2011, St John's Newfoundland. Provides an overview of a usability study conducted on WorldCat Local (WCL), a catalogue for ...
    • Seeing Double at Memorial University: Two WorldCat Local Usability Studies 

      Fahey, Sue; Gordon, Shannon; Rose, Crystal (The Editorial Board of Partnership: The Canadian Journal of Library and Information Practice and Research, 2011)
      Obtaining user feedback is valuable yet often overlooked, so when Memorial University Libraries launched OCLC’s WorldCat Local discovery tool for Fall 2010, usability testing was a logical next step. Two branches, each ...
    • Selecting the Selection Tool 

      Fahey, Sue; Gordon, Shannon (2010-06-01)
      Presentation slides as presented at the CHLA Conference, 2010, Kingston. Authors explain how the book ordering process at Memorial University works, discuss author experiences in evaluating electronic book selection tools, ...
    • A Selective Na+ Aptamer Dissected by Sensitized Tb3+ Luminescence 

      Zhou, Wenhu; Ding, Jinsong; Liu, Juewen (Wiley, 2016-08-17)
      A previous study of two RNA-cleaving DNAzymes, NaA43 and Ce13d, revealed the possibility of a common Na+ aptamer motif. Because Na+ binding to DNA is a fundamental biochemical problem, the interaction between Ce13d and Na+ ...
    • Self versus examiner administration of the Ocular Surface Disease Index© 

      Ngo, William; Srinivasan, Sruthi; Keech, Adam; Keir, Nancy; Jones, Lyndon W. (Elsevier, 2017-01)
      Purpose: To compare the difference in Ocular Surface Disease Index© (OSDI) scores when participants were given the OSDI to complete on their own (self-guided, SG), versus under the guidance of the examiner (examiner-guided, ...

    • Self-healable and reversible liposome leakage by citrate-capped gold nanoparticles probing initial adsorption/desorption induced lipid phase transition 

      Wang, Feng; Liu, Juewen (Royal Society of Chemistry, 2015-10-14)
      We herein report that the adsorption/desorption of citrate-capped gold nanoparticles (AuNPs) transiently causes leakage in fluid phase DOPC liposomes, while the liposomes do not leak with AuNPs capped with mercaptopropionic ...
