The analysis of the gas in a single expirate has long been used to estimate the degree of ventilation-perfusion (Va/Q) inequality in the lung. To further validate this estimate, we examined three measures of Va/Q inhomogeneity calculated from a single full exhalation in nine anesthetized mongrel dogs under control conditions and after exposure to aerosolized methacholine. These measurements wer...

We introduce a field-theoretic approach for describing the critical behavior of nonextensive systems, systems displaying global correlations among their degrees freedom, encoded by parameter q. As some applications, we report, to our knowledge, first analytical computation both universal static and dynamic q-dependent exponents O(N) vector models, valid all loop orders |q−1|<1. Then emerges new...

We study the differentiability of the stable norm ‖·‖ associated with a Zn periodic metric on Rn. Extending one of the main results of [Ba2], we prove that if p ∈ Rn and the coordinates of p are linearly independent over Q, then there is a linear 2-plane V containing p such that the restriction of ‖·‖ to V is differentiable at p. We construct examples where ‖·‖ it is not differentiable at a poi...

In a recent paper [l] K . CORRÁDI and A. HAJNAL proved that if a finite graph without multiple edges contains at least 3k vertices and the valency of every vertex is at least 2k, where k is a positive integer, then the graph contains k independent circuits, i . e . the graph contains as a subgraph a set of k circuits no two of which have a vertex in common . The present paper contains extension...

The series system means that both components must work for systems success. From probability concepts (independent events), the reliability (system success) of the above system (RAB) is given as: RAB = RA RB and the system unreliability (system failure), designated as Q is given as: QAB = 1 RAB = 1 RA RB considering that, Q + R = 1 or R = 1 Q, therefore, QAB = 1 (1 QA) (1 QB) = QA + QB QA QB Fo...

Using time-resolved small angle neutron scattering, we have measured the wave-number-dependent structure factor S(q) of monodisperse nanoemulsions that aggregate and gel after we suddenly turn on a strong, short-range, slippery attraction between the droplets. At high q, peaks in S(q) appear as dense clusters of droplets form, and S(q) increases strongly toward low q, as these dense clusters be...
