    • The shifted Turan sieve method on tournaments II 

      Kuo, Wentang; Liu, Yu-Ru; Ribas, Savio; Zhou, Kevin (Elsevier, 2021-12)
      In a previous work [5], we developed the shifted Turán sieve method on a bipartite graph and applied it to problems on cycles in tournaments. More precisely, we obtained upper bounds for the number of tournaments which ...
    • Shipment consolidation with two demand classes: Rationing the dispatch capacity 

      Satir, Benhur; Erenay, Fatih S.; Bookbinder, James H. (Elsevier, 2018-10-01)
      We analyze the problem faced by a logistics provider that dispatches shipment orders (parcels or larger packages) of two order classes, viz. expedited and regular. Shipment orders arrive according to a compound Poisson ...
    • Short Directed Cycles in Bipartite Digraphs 

      Seymour, Paul; Spirkl, Sophie (Springer Nature, 2020-08-01)
      The Caccetta-Häggkvist conjecture implies that for every integer k ≥ 1, if G is a bipartite digraph, with n vertices in each part, and every vertex has out-degree more than n/(k+1), then G has a directed cycle of length ...
    • Short-term forecasting and uncertainty analysis of wind turbine power based on long short-term memory network and Gaussian mixture model 

      Zhang, Jinhua; Yan, Jie; Infield, David; Liu, Yongqian; Lien, Fue-Sang (Elsevier, 2019-05)
      Wind power plays a leading role in the development of renewable energy. However, the random nature of wind turbine power and its associated uncertainty create challenges in dispatching this power effectively in the power ...
    • Short-Term Moderately Elevated Intraocular Pressure Is Associated With Elevated Scotopic Electroretinogram ResponsesShort-Term Elevated IOP and Scotopic ERG Responses 

      Choh, Vivian Cheng-Pei; Gurdita, Akshay; Tan, Bingyao; Prasad, Ratna C.; Bizheva, Kostadinka; Joos, Karen M. (Association of Research in Vision and Ophthalmology, 2016-04-01)
      Moderately elevated intraocular pressure (IOP) is a risk factor for open-angle glaucoma. Some patients suffer glaucoma despite clinically measured normal IOPs. Fluctuations in IOP may have a significant role since IOPs are ...
    • Short-term predictions of transient shallow groundwater levels at local scale using data-driven models 

      Ju, Jiangyue; Rudolph, David L.; Lin, Jimmy; Behbooei, Morteza (University of Waterloo, 2023-05-15)
      Groundwater is a critical natural resource for human activities and a vital component of the hydrological cycle. The fluctuation of groundwater level (GWL) can be induced by the interplay of several natural processes and ...
    • Short-wave vortex instability in stratified flow 

      Bovard, Luke; Waite, Michael L (Elsevier, 2016-01)
      In this paper we investigate a new instability of the Lamb–Chaplygin dipole in a stratified fluid. Through numerical linear stability analysis, a secondary peak in the growth rate emerges at vertical scales about an order ...
    • Show me the numbers: a quantitative portrait of the attitudes, experiences, and values of philosophers of science regarding broadly engaged work 

      Plaisance, Kathryn S.; Graham, Alexander V.; McLevey, John; Michaud, Jay (Springer, 2019-09-23)
      Philosophers of science are increasingly arguing for the importance of doing scientifically- and socially-engaged work, suggesting that we need to reduce barriers to extra-disciplinary engagement and broaden our impact. ...
    • Shy children's understanding of irony: Better comprehension does not always mean better socioemotional functioning 

      Mewhort-Buist, Tracy A.; Nilsen, Elizabeth S. (Wiley, 2019-04-12)
      Childhood shyness is a risk factor for negative socioemotional outcomes including loneliness and depression. Childhood shyness has also been found to relate to various aspects of pragmatic language. For instance, shyer ...
    • Shy individuals’ interpretations of counterfactual verbal irony 

      Mewhort-Buist, Tracy A.; Nilsen, Elizabeth S. (Taylor & Francis, 2017-10-31)
      Counterfactual verbal irony, an evaluative form of figurative language wherein a speaker’s intended meaning is opposite to the literal meaning of his or her words, is used to serve many social goals. Despite recent calls ...
    • Sieve estimation in a Markov illness-death process under dual censoring 

      Cook, Richard J.; Boruvka, Audrey (Oxford Journals, 2016-02-29)
      Semiparametric methods are well-established for the analysis of a progressive Markov illness-death process observed up to a noninformative right censoring time. However often the intermediate and terminal events are ...
    • Sieve methods in combinatorics 

      Liu, Yu-Ru; Murty, M. Ram (Elsevier, 2005-07)
      We develop the Turán sieve and a ‘simple sieve’ in the context of bipartite graphs and apply them to various problems in combinatorics. More precisely, we provide applications in the cases of characters of abelian groups, ...
    • Sieve Methods in Random Graph Theory 

      Liu, Yu-Ru; Saunders, J.C. (Springer, 2023-04-03)
      In this paper, we apply the Turán sieve and the simple sieve developed by R. Murty and the first author to study problems in random graph theory. In particular, we obtain upper and lower bounds on the probability of a ...
    • SIGCHI Games: The Scope of Games and Play Research at CHI 

      Nacke, Lennart; Cox, Anna; Mandryk, Regan; Cairns, Paul (ACM, 2016-05-07)
      The games research community at CHI has become an ever-growing significant part of the conference, demonstrated by the SIGCHI-sponsored CHI PLAY conference and the inclusion of a games subcommittee at CHI 2016. Given the ...
    • The Significance of the Personal within Disability Geography 

      Worth, Nancy (Wiley, 2008-09-01)
      Drawing on in-depth qualitative data, this article critically examines disability geography as a subfield where the personal is highly valued. The value and the risks inherent in this personal approach will be evaluated, ...
    • A Silver DNAzyme 

      Saran, Runjhun; Liu, Juewen (American Chemical Society, 2016-04-05)
      Silver is a very common heavy metal, and its detection is of significant analytical importance. DNAzymes are DNA-based catalysts; they typically recruit divalent and trivalent metal ions for catalysis. Herein, we report a ...
    • Similar hibernation physiology in bats across broad geographic ranges 

      McGuire, Liam P.; Fuller, Nathan W.; Dzal, Yvonne A.; Haase, Catherine G.; Silas, Kirk A.; Willis, Craig K.R.; Olson, Sarah H.; Lausen, Cori L. (Springer, 2021-08-23)
      Species with broad geographic ranges may experience varied environmental conditions throughout their range leading to local adaptation. Variation among populations reflects potential adaptability or plasticity, with ...
    • A simple and complex physical model of the Laurentian Great Lakes used to engage students and community members 

      Marshall, Stephen; McDonald, Corina; Johnston, John (The Geological Society of America North-Central Section, 2015-05-19)
      The Laurentian Great Lakes, Earth’s most-easily recognized feature from space, is of a size, complexity, and significance that can be difficult to comprehend. To address this we have developed corresponding simple and ...
    • A simple droplet merger design for controlled reaction volumes 

      Chen, Xiaoming; Brukson, Alexander; Ren, Carolyn L. (Springer Nature, 2017-04-01)
      Droplet microfluidics has been proven to be a viable platform for a variety of reactions by using uniform droplets well encapsulated by an immiscible carrier medium as reaction vesicles. Merging as one of the most basic ...
