S U M M A R Y Lateral variations in mantle anelasticity (Q) are important for understanding the Earth’s thermal and chemical structure in the mantle. In the past decades, preliminary global 3-D tomographic Q models have been developed based upon the assumption that traveltime (phase delay) anomalies are due to the Earth’s elastic (velocity) structure whereas amplitude anomalies are dominated by...

BACKGROUND Most studies that describe circadian variations in asthma have used maximum rate of peak expiratory flow (PEF) rather than forced expiratory volume in one second (FEV1) to assess airway calibre. This study was designed to assess circadian variations in PEF and FEV1 measured simultaneously and to compare variations in these measurements in normal and asthmatic subjects in a stable cli...

The geometry of an accelerator cavity determines its eigenmodes and thereby its performance characteristics. Therefore, accelerating performance and wakefield characteristics may be improved by an intentional modification of the geometry. However, undesired geometry perturbations due to manufacturing tolerances and operational demands can likewise impair it. To analyze the effects of geometry v...

In a previous work the eigenmodes of a muffin–tin structure limited with lateral electric walls were calculated using the mode matching technique. Now a modulated off axis beam is introduced and the beam induced fields, as well as the longitudinal coupling impedances are calculated. Furthermore, in order to get the fields in case of the open structure, the discrete set of modes in the field exp...

We give an exponentially-accurate normal form for a Lagrangian particle moving in a rotating shallow-water system in the semi-geostrophic limit, which describes the motion in the region of an exponentially-accurate slow manifold (a region of phase space for which dynamics on the fast scale are exponentially small in the Rossby number). We show how this result is related to the variational asymp...

In this paper, we show that for a polyhedral multifunction F : R n ! R m with convex range, the inverse function F ?1 is locally lower Lipschitzian at every point of the range of F (equivalently Lipschitzian on the range of F) if and only if the function F is open. As a consequence, we show that for a piecewise aane function f : R n ! R n , f is surjective and f ?1 is Lipschitzian if and only i...

We have assessed individual variations in urinary acidic metabolite excretion and the effects of extreme alterations in dietary composition on these metabolites in selected normal persons who we considered representative of the general ambulant normal population. Extreme dietary alterations produced relatively small changes in the patterns or amounts of metabolite excretion, but large individua...
