Continuous Respiratory Oscillometry in Pediatric Laparoscopic Surgery—The COMET Study
Pediatric Anesthesia, EarlyView.ABSTRACT Background Laparoscopic appendectomy is the accepted surgical approach for appendicitis in centers worldwide. Laparoscopic surgery requires the creation of a pneumoperitoneum to facilitate surgical access. Laparoscopic surgery affects the respiratory mechanics of patients under general anesthesia.

Two-dimensional analysis of a simplified fluidic oscillator
Mechanical Engineering Journal, 2018 In order to investigate a self-excited oscillatory phenomenon of a two-dimensional confined jet with a cylinder as a downstream target, the authors conduct two-dimensional numerical analyses based on vorticity ζ and stream function ψ using a finite ...

Polymer International, EarlyView.Sulfonated polystyrene films with different degrees of sulfonation were fabricated using Langmuir–Schaefer and drop‐casting techniques. Both the deposition method and sulfonation level strongly affect film morphology and electrical response, governing the performance of these materials as ammonia gas sensors.

IEEE Journal of Translational Engineering in Health and Medicine, 2016 Current totally implantable wireless blood flow monitors are large and cannot operate alongside nearby monitors. To alleviate the problems with the current monitors, we developed a system to monitor blood flow wirelessly, with a simple and easily ...

Perforation Enhances Sound Insulation in Plate Lattice Metamaterials
Small, EarlyView.Herein, perforations are engineered into face‐centered cubic plate lattice metamaterials to convert normally detrimental openings into acoustically active features. Experiments, finite‐element analyses, and a reduced‐order transfer‐matrix model show that selected perforation geometries activate Helmholtz‐like and cavity‐mediated resonances, enhancing ...

Animal Conservation, EarlyView.During their spawning migration, European silver eels frequently encounter hydropower facilities where successful downstream passage is essential for the conservation of this critically endangered species. In this study, we evaluated how three angled rack designs and individual behavioral variation influenced downstream passage success in large‐scale ...

Entomologia Experimentalis et Applicata, EarlyView.Female parasitoids can lower competitive costs by detecting rival‐species cues on shared host fruits (host habitats). We compared native Doryctobracon areolatus and introduced Diachasmimorpha longicaudata on guava fruits infested with Anastrepha fraterculus.
