Coeliac disease in children and adults is considered to be a variety of the same disorder. This gains epidemiological support in the present study, which reports on the observed prevalence of coeliac disease in an area of Sweden (population, 140 500). On 1 July 1981, the prevalence rate was found to be 104/100 000 (1:960) among children, and the same figure, 106/00 000 (1:950), was found for co...

High-performance size exclusion chromatography with multiangle laser light scattering detection (HPSEC-MALLS) was used for characterizing complete molecular weight distributions for a range of commercial alginates used as ice cream stabilizers. For the samples investigated, molecular weight averages were found to vary between 115 000 and 321 700 g/mol and polydispersity indexes varied from 1. 5...

We read with interest the paper by Black and colleagues which outlines the current status of CT screening, and value the authors’ cautious interpretation of the relatively few well conducted studies regarding this controversial topic. However, when using reduction in lung cancer mortality as proof of screening efficacy with CT due to early intervention, one has to be careful in interpreting the...

Suppose for simplicity that our system consists of a single qubit. We start with errors we are familiar with from the classical setting – bit-flips. Such an error converts the original state, say α|0〉+β |1〉, into α|1〉+β |0〉. We can correct these kind of errors using classical error correcting codes. For example, we may use a repetition code, i.e., encoding |0〉 as |000〉 and |1〉 as |111〉. Thus, w...
