BACKGROUND IgG subclass deficiency is often associated with recurrent pulmonary infections. The prevalence of deficiency in a large well characterised group of patients with bronchiectasis has not previously been established. METHODS Serum IgG subclass concentrations in 89 patients with bronchiectasis were compared with those obtained from a group of 82 age and sex matched normal healthy cont...

We study the problems of deciding consistency and performing variable elimination for disjunctions of linear inequalities and disequations with at most one inequality per disjunction. This new class of constraints extends the class of generalized linear constraints originally studied by Lassez and McAloon. We show that deciding consistency of a set of constraints in this class can be done in po...

Baxter permutations are a class of permutations which are in bijection with a class of floorplans that arise in chip design called mosaic floorplans. We study a subclass of mosaic floorplans called Hierarchical Floorplans of Order k defined from mosaic floorplans by placing certain geometric restrictions. This naturally leads to studying a subclass of Baxter permutations. This subclass of Baxte...

The macrolide resistance determinants and genetic elements carrying the mef(A) and mef(E) subclasses of the mef gene were studied with Streptococcus agalactiae isolated in 2003 and 2004 from 7,084 vaginorectal cultures performed to detect carrier pregnant women. The prevalence of carriage was 18% (1,276 isolates), and that of erythromycin resistance 11.0% (129 of the 1,171 isolates studied). er...

This paper deals with a new subclass of univalent function associated the right half lemniscate Bernoulli. We have find upper bound Hankel determinant H3(1) for this by applying Carlson–Shaffer operator to it. The present work also certain properties newly defined subclass, such as order 3, co-efficient estimate, etc.

Using $ (p, q) $-Lucas polynomials and bi-Bazilevic type functions of order $\rho +i\xi,$ we defined a new subclass biunivalent functions. We obtained coefficient inequalities for belonging to the subclass. In addition these results, upper bound Fekete-Szegö functional was obtained. Finally, some special values parameters, several corollaries were presented.

In the present paper, we introduce and study a subclass of analytic univalent functions associated with Beta negative binomial distribution series which is defined in open unit disk U. We discuss some important geometric properties this subclass, like, coefficient estimates, extreme points integral representation. Also, obtain results about mean fractional integral.

Acyclic phase-type distributions form a versatile model, serving as approximations to many probability distributions in various circumstances. They exhibit special properties and characteristics that usually make their applications attractive. Compared to acyclic continuous phase-type (ACPH) distributions, acyclic discrete phase-type (ADPH) distributions and their subclasses (ADPH family) have ...

When an ordering among parameters is known in advance,the problem of estimating the smallest or the largest parametersarises in various practical problems. Suppose independent randomsamples of size ni drawn from two gamma distributions withknown arbitrary shape parameter no_i > 0 and unknown scale parameter beta_i > 0, i = 1, 2. We consider the class of mixed estimators of 1 and 2 under the res...
