The objective of this study was to describe a standardised and non-invasive method for exhaled breath condensate (EBC) collection in cats and to test whether determination of hydrogen peroxide (H2O2) in EBC might be used as marker of lower airway inflammation. The technique of barometric whole body plethysmography for cats was combined with a system to condense the effluent air from the plethysmograph, allowing simultaneous EBC collection and respiratory pattern measurement. H2O2 was determined spectrophotometrically. Eighteen experimental cats were used to investigate the impact on EBC volume and EBC H2O2 of plethysmograph ventilation rate, collection duration, sample stability, within-day and day-to-day variability. After determination of a standardised EBC collection procedure, correlation analyses between EBC H2O2 and bronchoalveolar lavage (BAL) cytology of healthy and allergen-challenged Ascaris suum (AS)-sensitised cats were performed. A significant and positive correlation between EBC H2O2 and bronchoalveolar lavage (BAL) neutrophil% was found in healthy cats (P < 0.001, r = 0.55), whereas in AS-sensitised cats, correlation with BAL eosinophil% was significant (P < 0.005, r = 0.61). H2O2 was increased after an allergen challenge in AS-sensitised cats (n = 6, 0.56 ± 0.12 versus 1.08 ± 0.35 μ mol/L, P < 0.05). This study proposes a non-invasive, well tolerated and repeatable method of EBC collection for cats and suggests that EBC H2O2 might be used as non-invasive biomarker for monitoring lower airway inflammation.

This paper studies the role of alternative pension systems that offer collective annuities. The defining characteristic of collective annuities is that they do not depend on an individual’s survival probabilities. We show that such a system may be welfare improving (with a utilitarian social welfare function) even when private annuity markets are perfect and when life expectancy and earning abilities are positively correlated (i.e., in a setting that is a priori biased against collective annuities). We first concentrate on linear pension systems and contrast two schemes: a pure contributory (Bismarckian) pension and a flat rate (Beveridgean) pension. We show that the case for collective annuities is stronger when they are associated with a flat pension system. Then we analyze nonlinear pension schemes.We show that the solution can be implemented by a pension scheme associated with annuities that reflect some degree of “collectiveness.” Unlike under pure collective annuities, benefits do depend on life expectancy but to a lesser degree than with actuarially fair private annuities. In other words, the impact of survival probabilities is mitigated rather than completely neutralized. [less ▲]

This article aims at providing an overview of the national case law on collective dominance in Europe. We observe that overall, most domestic decisions have manifestly integrated the EU case law and followed the shift from a structural approach towards a more behavioral approach. We higlight several protruding cases on the definition of the notion of abuse and the most creative remedies devised by national competition authorities so far. [less ▲]

The growth of a solid phase in a liquid medium containing randomly dispersed mesoscopic impurities is discussed. Particles represent hindrances for the growth front. They can remain static or can be pushed by the advancing interface. The physics of the collective particle motion is outlined. Experiments with A12O3-SiO2 impurities in KC1 crystal serve as illustrative examples. The collective effects due to the particle concentration are investigated through a kinetic growth model.

This paper addresses the design of mobile sensor networks for optimal data collection. The development is strongly motivated by the application to adaptive ocean sampling for an autonomous ocean observing and prediction system. A performance metric, used to derive optimal paths for the network of mobile sensors, defines the optimal data set as one which minimizes error in a model estimate of the sampled field. Feedback control laws are presented that stably coordinate sensors on structured tracks that have been optimized over a minimal set of parameters. Optimal, closed-loop solutions are computed in a number of low-dimensional cases to illustrate the methodology. Robustness of the performance to the influence of a steady flow field on relatively slow-moving mobile sensors is also explored. [less ▲]
