Improving Free-Piston Stirling Engine Specific Power [PDF]
12th International Energy Conversion Engineering Conference, 2014 This work uses analytical methods to demonstrate the potential benefits of optimizing piston and/or displacer motion in a Stirling engine. Isothermal analysis was used to show the potential benefits of ideal motion in ideal Stirling engines. Nodal analysis is used to show that ideal piston and displacer waveforms are not optimal in real Stirling ...

Methods for Discerning the Impact of Mucus on Host Defenses Against Viral Infection
Current Protocols, Volume 5, Issue 9, September 2025.Abstract Mucus is an important component of airway host defenses that acts by enabling the trapping and clearance of infectious materials such as bacteria and viruses. It can be difficult, however, to design experiments that independently determine the extent to which mucus contributes to innate barrier functions in the lung.
