the association of hla and disease varies in different populations. we have . studied the association of hla class i in iranian psoriatic patients, in order to compare this association with other reports. fifty-one iranian patients with psoriasis were hla typed. the frequency of hla antigens in patients and patient subgroups, based on clinical patterns, age of onset, family history and provocat...

BACKGROUND Acute lower respiratory illness (ALRI) is a major global cause of morbidity and mortality among children under 5. Antibiotic treatment for ALRI is inexpensive and decreases case fatality, but care-seeking patterns and appropriate treatment vary widely across countries. This study sought to examine patterns of appropriate treatment and estimate the burden of cases of untreated ALRI in...

We consider coordination in cascade networks and construct sequences of polar codes that achieve any point in a special region of the empirical coordination capacity region. Our design combines elements of source coding to generate actions with the desired type with elements of channel coding to minimize the communication rate. Moreover, we bound the probability of malfunction of a polar code f...

As the rst step in an automated text sum-marization algorithm, this work presents a new method for automatically identifying the central ideas in a text based on a knowledge-based concept counting paradigm. To represent and generalize concepts, we use the hierarchical concept taxonomy WordNet. By setting appropriate cutoo values for such parameters as concept generality and child-to-parent freq...

The dinuclear bis(2,2’-bipyridine)ruthenium complex of 4,5-di(2-pyridyl)imidazolate has been prepared and separated into its (meso and rac) diastereoisomers. The 2-phenyl substituted analogue forms the meso isomer selectively. All three complexes have been characterised by H NMR and X-ray crystallography. Electrochemical measurements and spectroelectrochemistry of the mixedvalence states reveal...

In an attempt to rlucidatc the mrrhnnism of the enzymic hydrosylation of aromatic compounds, we have isolated and partislly purified an aromatic hydrosglase from a soil bacterium. This enzyme, which will be referred to as “salicylate hydroxylase,” is soluble and relatively stable, in contrast to most hitherto known aromatic hydrosylascs, and ratalyzes a stoichiometric conversion of salicylate ‘...

In this study, poly carbonate (PC) and poly (ethylene terephthalate) (PET) were reactive melt-blended under two different conditions to produce PC/PET copolymers. For each condition, samples were taken at specified mixing times representative a specific structure of copolymers and each one employed to physically compatibilize a PC/PET blend with a fixed composition. Reactive blending and copoly...
