BMC Anesthesiology, 2020 Background Alveolar recruitment maneuvers enable easily reopening nonaerated lung regions via a transient elevation in transpulmonary pressure. To evaluate the effect of these maneuvers on respiratory resistance, we used an oscillatory technique during ...

Forced oscilation technique and hyperinflation in COPD
Revista Portuguesa de Pneumologia, 2008 AbstractForced oscillation technique (FOT) is a simple method used to measure the mechanical impedance of the respiratory system.It can be a valuable test in poorly cooperative patients (pts) and in severe COPD.Little information exists concerning its value on hyperinflation in COPD pts.The aim of this study was to analyze the correlation (corr ...

Synchronization and chaos control in a periodically-forced, quasi-geostrophic, two-layer model of baroclinic instability [PDF]
, 2006 Cyclic forcing on many timescales is believed to have a significant effect on various quasi-periodic, geophysical phenomena such as El Niño, the Quasi-Biennial Oscillation, and glacial cycles.

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Advanced Engineering Materials, EarlyView.Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Interval Oscillation Criteria for Second-Order Forced Functional Dynamic Equations on Time Scales
Discrete Dynamics in Nature and Society, 2014 This paper is concerned with oscillation of second-order forced functional dynamic equations of the form (r(t)(xΔ(t))γ)Δ+∑i=0nqi(t)|x(δi(t))|αisgn x(δi(t))=e(t) on time scales. By using a generalized Riccati technique and integral averaging techniques,

A Novel Approach to Estimate the Transition Temperature via Dynamic Nanoindentation
Advanced Engineering Materials, EarlyView.A new dynamic nanoindentation‐based method was developed that uses the stiffness ratio as an indicator of the elastic–plastic deformation contributions at different temperatures. The approach successfully identified transition temperatures in ferritic steel and distinguished them from continuously ductile austenitic steel.

The volume-dependent Forced Oscillation Technique
IFAC-PapersOnLine, 2018 Abstract This paper describes a novel extension of the Forced Oscillation Technique (FOT), namely the volume-dependent Forced Oscillation Technique (v-FOT). This extension is based on the measurement of the respiratory impedance over the whole lung volume.
