Feather function and the evolution of birds
Biological Reviews, Volume 98, Issue 2, Page 540-566, April 2023., 2023 ABSTRACT The ability of feathers to perform many functions either simultaneously or at different times throughout the year or life of a bird is integral to the evolutionary history of birds. Many studies focus on single functions of feathers, but any given feather performs many functions over its lifetime. These functions necessarily interact with each

Advanced Control for Applications, Volume 4, Issue 2, June 2022., 2022 Abstract Predictive functional control (PFC) is a straightforward and cheap model‐based technique for systematic control of well‐damped open‐loop processes. Nevertheless, its oversimplified design characteristics are often the cause of diminished efficacy in more challenging applications; processes involving lightly damped and/or unstable dynamics have

Energy and AI, 2021 The intermittent nature of operation and unpredictable availability of renewable sources of energy (e.g., wind and solar) would require the combustors in fossil-fuel power plants, sharing the same grid, to operate with large turn-down ratios. This brings

Advanced Biology, Volume 5, Issue 11, November 2021., 2021 Microvessels‐on‐chips are advanced in vitro models that are currently considered as future replacements of animal models. However, the high‐throughput use of microvessels‐on‐chips for patient‐on‐a‐chip studies is still lacking. This study develops an innovative method for screening plasma samples in the microvessel‐on‐a‐chip platforms that can be ...

International Journal of Laboratory Hematology, Volume 43, Issue 1, Page 29-39, February 2021., 2021 Abstract Introduction In 2015, Sysmex launched a new series of hematology analyzers (XN‐L Series) designed to fulfill the needs of niche laboratories in areas such as pediatrics, dialysis, neurology, and oncology while providing a compact solution. In this study, we evaluate the whole blood and body fluid modes of one of these analyzers, the XN‐350 ...

Rijke Organ: Modeling and Control of Array of Rijke Tubes
IFAC-PapersOnLine, 2020 Abstract Rijke tube is a popular physical experiment demonstrating a spontaneous generation of sound in an open vertical pipe with a heat source. This laboratory instance of thermoacoustic instability has been researched due to its significance in practical thermoacoustic systems.

Transition to Instability in Segmented Rijke Tube [PDF]
The Open Thermodynamics Journal, 2009 Thermoacoustic instabilities can arise in systems where unsteady heat release is favorably coupled with acous- tic pressure oscillations. A modified Rijke tube with segments having different sections is found to have lower threshold levels of heat addition rate needed for exciting the fundamental acoustic mode of the tube.
