All-optical generation and photoassociative probing of sodium Bose-Einstein condensates
, 2006 We demonsatrate an all optical technique to evaporatively produce sodium Bose-Einstein condensates (BEC). We use a crossed-dipole trap formed from light near 1060 nm, and a simple ramp of the intensity to force evaporation.

Novel Device for Measuring Lung Function using Oscillometry [PDF]
, 2020 The forced oscillation technique (FOT) is a non-invasive means of measuring lung mechanics. Broad-band oscillations in flow are delivered to the lungs while the resultant pressure oscillations are recorded.

Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics
Advanced Engineering Materials, EarlyView.Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.

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,

Forced oscillation technique for optimising PEEP in ventilated extremely preterm infants [PDF]
European Respiratory Journal, 2020 Ventilatory settings are critical in mechanically ventilated extremely preterm newborn infants due to the risk of ventilation induced lung injury (VILI) and subsequent development of bronchopulmonary dysplasia (BPD) [1]. The positive end-expiratory pressure (PEEP) settings usually rely on blood gases, oxygen requirement, lung auscultation, evaluation ...
