    • Perceived timing of active head movement at different speeds 

      Sachgau, Carolin; Chung, William; Barnett-Cowan, Michael (Elsevier, 2018-11-20)
      The central nervous system must determine which sensory events occur at the same time. Actively moving the head corresponds with large changes in the relationship between the observer and the environment, sensorimotor ...

    • Periodic Adaptive Stabilization of Rapidly Time-Varying Linear Systems 

      Simard, Joel D.; Nielsen, Christopher; Miller, Daniel E. (Springer, 2019-06-19)
      Adaptive control deals with systems that have unknown and/or time-varying parameters. Most techniques are proven for the case in which any time variation is slow, with results for systems with fast time variations limited ...
    • Peripheral Quantitative Computed Tomography: Review of Evidence and Recommendations for Image Acquisition, Analysis, and Reporting, Among Individuals With Neurological Impairment 

      Cervenka, Tomas; Giangregorio, Lora M.; Sievänen, Harri T.; Cheung, Angela M.; Craven, Beverly C. (Elsevier, 2018-10)
      In 2015, the International Society for Clinical Densitometry (ISCD) position statement regarding peripheral quantitative computed tomography (pQCT) did not recommend routine use of pQCT, in clinical settings until consistency ...

      Busch, Marc; Mattheiss, Elke; Orji, Rita; Marczewski, Andrzej; Hochleitner, Wolfgang; Lankes, Michael; Nacke, Lennart; Tscheligi, Manfred (Association for Computing Machinery, 2015-10)
      Serious and persuasive games and gamified interactions have become popular in the last years, especially in the realm of behavior change support systems. They have been used as tools to support and influence human behavior ...
    • Personalizing Persuasive Strategies in Gameful Systems to Gamification User Types 

      Orji, Rita; Fortes Tondello, Gustavo; Nacke, Lennart (Association for Computing Machinery, 2018-04-21)
      Persuasive gameful systems are effective tools for motivating behaviour change. Research has shown that tailoring these systems to individuals can increase their efficacy; however, there is little knowledge on how to ...
    • Perspective: Maintaining surface-phase purity is key to efficient open air fabricated cuprous oxide solar cells 

      Hoye, Robert L. Z.; Brandt, Riley E.; Ievskaya, Yulia; Heffernan, Shane; Musselman, Kevin P.; Buonassisi, Tonio; MacManus-Driscoll, Judith L. (AIP Publishing, 2015-02-01)
      Electrochemically deposited Cu2O solar cells are receiving growing attention owing to a recent doubling in efficiency. This was enabled by the controlled chemical environment used in depositing doped ZnO layers by atomic ...
    • Perspectives on software-defined networks: interviews with five leading scientists from the networking community 

      Batista, Daniel M.; Blair, Gordon; Kon, Fabio; Boutaba, Raouf; Hutchison, David; Jain, Raj; Ramjee, Ramachandran; Rothenberg, Christian Esteve (SpringerOpen, 2015-10-30)
      Software defined Networks (SDNs) have drawn much attention both from academia and industry over the last few years. Despite the fact that underlying ideas already exist through areas such as P2P applications and active ...
    • Petroleomic analysis of the treatment of naphthenic organics in oil sands process-affected water with buoyant photocatalysts 

      Leshuk, Tim; Peru, Kerry M.; de Oliveira Livera, Diogo; Tripp, Austin; Bardo, Patrick; Headley, John V.; Gu, Frank (Elsevier, 2018-09-15)
      The persistence of toxicity associated with the soluble naphthenic organic compounds (NOCs) of oil sands process-affected water (OSPW) implies that a treatment solution may be necessary to enable safe return of this water ...
    • pH-Responsive Poly(Ethylene Glycol)- block -Polylactide Micelles for Tumor-Targeted Drug Delivery 

      Xiao, Lin; Huang, Lixia; Moingeon, Firmin; Gauthier, Mario; Yang, Guang (American Chemical Society, 2017-08-16)

    • A Phase Model with Large Time Delayed Coupling 

      Al-Darabsah, Islam; Campbell, Sue Ann (Elsevier, 2020-10)
      We consider two identical oscillators with weak, time delayed coupling. We start with a general system of delay differential equations then reduce it to a phase model. With the assumption of large time delay, the resulting ...
    • Phase models and clustering in networks of oscillators with delayed coupling 

      Campbell, Sue Ann; Wang, Zhen (Elsevier, 2017-09-19)
      We consider a general model for a network of oscillators with time delayed coupling where the coupling matrix is circulant. We use the theory of weakly coupled oscillators to reduce the system of delay differential equations ...
