  James, Patrice; Harding, Máiréad; Beecher, Tara; Browne, Deirdre; Cronin, Michael; Guiney, Helena; O'Mullane, Denis; Whelton, Helen (Sage Publications, 2020-12-21)

  Guidance intended to reduce fluoride toothpaste ingestion in early childhood was introduced in Ireland in 2002. In 2007, water fluoride concentration was adjusted from 0.8–1.0 to 0.6–0.8 ppm. The objective of this study ...
• Tapered nonlinear vibration energy harvester for powering Internet of Things 

  Paul, Kankana; Amann, Andreas; Roy, Saibal (Elsevier Ltd., 2020-11-30)

  The lack of a sustainable power source to substitute batteries for long-term applications limits the widespread deployment of wireless sensor nodes in this era of the Internet of Things. Conventional linear Vibration Energy ...
• Weak tracking in nonautonomous chaotic systems 

  Alkhayuon, Hassan; Ashwin, Peter (American Physical Society, 2020-11-19)

  Previous studies have shown that rate-induced transitions can occur in pullback attractors of systems subject to “parameter shifts” between two asymptotically steady values of a system parameter. For cases where the ...
• Tipping phenomena and points of no return in ecosystems: beyond classical bifurcations 

  O'Keefe, Paul E.; Wieczorek, Sebastian (Society for Industrial and Applied Mathematic, SIAM, 2020-10-22)

  We discuss tipping phenomena in nonautonomous systems using an example of a bistable ecosystem model with environmental changes represented by time-varying parameters [Scheffer et al., Ecosystems, 11 (2008), pp. 275--279]. ...
