- We review the status of the AMANDA neutrino telescope. We present resultsobtained from the four-string prototype array AMANDA-B4 and describe themethods of track reconstruction and neutrino event separation. We give also firstresults of the analysis of the 10-string detector AMANDA-B10, in particular onatmospheric neutrinos and the search for magnetic monopoles. We sketch thefuture schedule on the way to a cube kilometer telescope at the South Pole,ICECUBE.

- We present a selection of results based on data taken in 1997 with the 302-PMT Antarctic Muon and Neutrino Detector Array-B10 ("AMANDA-B10") array. Atmospheric neutrinos created in the northern hemisphere are observed indirectly through their charged current interactions which produce relativistic, Cherenkov-light-emitting upgoing muons in the South Pole ice cap. The reconstructed angular distribution of these events is in good agreement with expectation and demonstrates the viability of this ice-based device as a neutrino telescope. Studies of nearly vertical upgoing muons limit the available parameter space for WIMP dark matter under the assumption that WIMPS are trapped in the earth's gravitational potential well and annihilate with one another near the earth's center.

Observation of high energy atmospheric neutrinos with AMANDA

Konferensbidrag (refereegranskat)abstract
- In 1997 the Antarctic Muon and Neutrino Detector Array (AMANDA) started operating with 10 strings. In an analysis of data taken during the first year of operation 188 atmospheric neutrino candidates were found. Their zenith angle distribution agrees with expectations based on Monte Carlo simulations. A preliminary upper limit is given on a diffuse flux of high energy neutrinos of astrophysical origin.

- Background:The known genetic causes for Parkinson’s disease (PD) onlyexplain a small proportion of the familial aggregation of PD. Despiteintensive efforts by researchers internationally, identifying and confirmingadditional monogenic causes for PD has been difficult.Methods:We examined 16 members of a large family with multi-incidentPD and dementia. Eight members were examined by whole exome (WES)or whole genome sequencing. Rare variants co-segregating with the disease were evaluated based on their distribution in additional familymembers and known gene functions. WES data from 843 PD cases and 885controls were screened for the two most highly ranked candidate variantsand used for gene burden analysis.Results:Clinically, all affected family members had typical PD withcognitive decline. Two affected individuals showed typical PD neuropathology. Out of nine genetic variants identified, we highlighted two as goodcandidates for causing this family’s PD. However, co-segregation with PDwas imperfect and this study was complicated by the fact that somegenotyped family members showed mild motor symptoms of uncertaincause, or cognitive decline without apparent motor dysfunction. Geneburden analysis showed no difference between cases and controls in thefrequency of potentially deleterious variants in the top-candidate genes.Nonetheless, factors that could indicate an impact of either of the two topcandidate genetic variants were found as one of the variants was identifiedin one additional familial PD proband from the case series and geneticvariants in the other top-candidate gene had previously been associatedwith an increased risk for PD in humans.Conclusions: Our study was not able to determine a single high-impactvariant as the cause of PD with cognitive decline in the family despitedetailed clinical and genetic assessments, but we nominate two potentialcandidate variants. Reduced penetrance and phenocopies may complicategenomic studies of families with PD.
