Respiratory Function in Recurrent Pulmonary Embolism

Respiration, 2009
Pulmonary arterial and right atrial pressure, cardiac output, lung volumes, blood gases, VD/VT ratio and alveoloarterial oxygen tension gradient were measured in 21 subjects with pulmonary hypertension due to recurrent pulmonary emboli. The mean pressure in pulmonary artery ranged from 19.5 to 97.0 mm Hg.

Lymphocyte function in recurrent aphthous ulceration

Journal of Oral Pathology & Medicine, 1985
Lymphocyte blast transformation responses to mitogens and to streptococcal, adenovirus Type I, and oral mucosal antigens were studied in 32 patients with recurrent aphthous ulceration (RAU) and matched control subjects. RAU patients showed significantly depressed (p<0.05) responses to mitogens in comparison with matched controls, but there was no ...

Hypergraphic Functions and Bifurcations in Recurrence Relations

SIAM Journal on Applied Mathematics, 1978
In this paper, bifurcations of the recurrence relation $X_{n + 1} = F( {X_n } )$ are studied. For a certain class of functions F, it is proved that when any cycle bifurcates, it produces a nearby one of double the period. The class of functions is defined by a differential inequality which is satisfied by several functions that have been used in models

Growth Functions for Groups and Recurrence Sequences

Proceedings of the London Mathematical Society, 1991
Let \(G\) be a group generated by a finite set \(S\), and let \(H\) be a subgroup of \(G\). We define the length \(\ell^ H_ S(Hg)\) of the coset \(Hg\) to be the least value of \(n\) such that \(Hg = Hs_ 1s_ 2 \dots s_ n\) \((s_ i \in S \cup S^{-1}\), \(i=1,\dots,n\)). [If one thinks geometrically in terms of the Cayley graph of \(G\) with respect to \(

Recurrences for hypergeometric functions

2003
Summary: Many of the known recurrences for the hypergeometric functions of several variables involve more than two parameters. A method is developed which allows a search of the functions for recurrences which involve only a specific number of the parameters, in particular, two parameter recurrences.

Recurrence Functions and Numerical Characteristics of Graphs

2001
We present a general method for the description of the structural meaning of the canonical representation coefficients of a wide class of the recurrence functions of graphs. The combinatorial objects, the so-called (j,k)-placements, are used. The algorithm, which can be realized on PC and allows to reveal some relations between the numerical ...
