- The radiation tolerance of three multimode optical fibres has been investigated to establish their suitability for the use in the front-end data links of the ATLAS experiment. Both gamma and neutron irradiation studies are reported. A step-index fibre with a pure silica core showed an induced attenuation of similar to 0.05 dB/m at 330 kGy(Si) and 1 x 10(15) n(1 MeV Si)/cm(2) and is suitable for use with the inner detector links which operate at 40-80 Mb/s. A graded-index fibre with a predominantly germanium-doped core exhibits an induced attenuation of similar to 0.1 dB/m at 800 Gy(Si) and 2 x 10(13) n(1 MeV Si)/cm(2) and is suitable for the calorimeter links which operate at 1.6 Gb/s. Measurements of the dose rate dependence of the induced attenuation indicate that the attenuation in ATLAS will be lower.

Large-scale copy number polymorphism in the human genome

- The extent to which large duplications and deletions contribute to human genetic variation and diversity is unknown. Here, we show that large-scale copy number polymorphisms (CNPs) (about 100 kilobases and greater) contribute substantially to genomic variation between normal humans. Representational oligonucleotide microarray analysis of 20 individuals revealed a total of 221 copy number differences representing 76 unique CNPs. On average, individuals differed by 11 CNPs, and the average length of a CNP interval was 465 kilobases. We observed copy number variation of 70 different genes within CNP intervals, including genes involved in neurological function, regulation of cell growth, regulation of metabolism, and several genes known to be associated with disease.

Magnetic interactions in MBE grown Fe/x Au/Tb trilayers
- 2002
-
Ingår i: Journal of Magnetism and Magnetic Materials. ; 242-245, s. 532-534
-
Tidskriftsartikel (refereegranskat)abstract
- Indirect exchange coupling between Fe and Tb layers showed oscillatory behaviour through Au layer as a function ofits thickness. Trilayers, prepared in the MBE system, were characterized with different experimental tools. Results are analysed to reconstruct the dynamics of Fe and Tb magnetic moments. For the first time, the change of sign in magnetic interaction is shown for Fe/Au/Tb system.

No excess risk of colorectal cancer among alcoholics followed for up to 25 years
- 2003
-

Tidskriftsartikel (refereegranskat)abstract
- We conducted a population-based retrospective cohort study among 179 398 Swedish patients hospitalised for alcoholism from 1970 to 1994, and found no excess risk for colorectal cancers, overall or at any anatomical subsite. Our findings challenge the hypothesis that alcohol intake is a risk factor for cancer of the large bowel.
