Physics with e + e - linear colliders
- 1998

Tidskriftsartikel (refereegranskat)abstract
- The physics potential of e + e - linear colliders is summarized in this report. These machines are planned to operate in the first phase at a center-of-mass energy of 500 GeV, before being scaled up to about 1 TeV. In the second phase of the operation, a final energy of about 2 TeV is expected. The machines will allow us to perform precision tests of the heavy particles in the Standard Model, the top quark and the electroweak bosons. They are ideal facilities for exploring the properties of Higgs particles, in particular in the intermediate mass range. New vector bosons and novel matter particles in extended gauge theories can be searched for and studied thoroughly. The machines provide unique opportunities for the discovery of particles in supersymmetric extensions of the Standard Model, the spectrum of Higgs particles, the supersymmetric partners of the electroweak gauge and Higgs bosons, and of the matter particles. High precision analyses of their properties and interactions will allow for extrapolations to energy scales close to the Planck scale where gravity becomes significant. In alternative scenarios, i.e. compositeness models, novel matter particles and interactions can be discovered and investigated in the energy range above the existing colliders up to the TeV scale. Whatever scenario is realized in Nature, the discovery potential of e + e - linear colliders and the high precision with which the properties of particles and their interactions can be analyzed, define an exciting physics program complementary to hadron machines.

Incidence of estimates of the disease burden of rotavirus in Sweden

- Laboratory and hospitalization data from two children's hospitals with large primary catchment areas and national laboratory and hospitalization data for children under 4 y of age with acute diarrhoea were compiled to estimate the number of hospitalizations and the cost burden associated with rotavirus diarrhoea in Sweden. According to our estimates 1500-1700 rotavirus-associated hospitalizations occur annually in Sweden in children under 4 y of age (3.7 hospitalizations/1000 children/y). This number represents 2.3% of admissions for all diagnoses in children of this age group. The cost of these hospitalizations is 13.5-15 million Swedish crowns (US$1.8-2 million). Serotyping by PCR for two years revealed that serotype 1 (G1) was the most common (49% and 58%, respectively) identified. Serotypes 2-4 were identified in the following proportions G2 (23% and 5%), G3 (21% and 0%) and G4 (7% and 16%). The national laboratory report data for 1993-96 show that as much as 7-13% of rotavirus infections occur in elderly people.

- 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.

Factor VIII gene inversions in severe hemophilia A : Results of an international consortium study

Tidskriftsartikel (refereegranskat)abstract
- Twenty-two molecular diagnostic laboratories from 14 countries participated in a consortium study to estimate the impact of Factor VIII gene inversions in severe hemophilia A. A total of 2,093 patients with severe hemophilia A were studied; of those, 740 (35%) had a type 1 (distal) factor VIII inversion, and 140 (7%) showed a type 2 (proximal) inversion. In 25 cases, the molecular analysis showed additional abnormal or polymorphic patterns. Ninety-eight percent of 532 mothers of patients with inversions were carriers of the abnormal factor VIII gene; when only mothers of nonfamilial cases were studied, 9 de novo inversions in maternal germ cells ware observed among 225 cases (≃ 1 de novo maternal origin of the inversion in 25 mothers of sporadic cases). When the maternal grandparental origin was examined, the inversions occurred de novo in male germ cells in 69 cases and female germ cells in 1 case. The presence of factor VIII inversions is not a major predisposing factor for the development of factor VIII inhibitors; however, slightly more patients with severe hemophilia A and factor VIII inversions develop inhibitors (130 of 642 [20%]) than patients with severe hemophilia A without inversions (131 of 821 [16%]).

The WHO-EURO Multicentre Study : risk of parasuicide and the comparability of the areas under study.

Ingår i: Crisis. - 0227-5910 .- 2151-2396. ; 17:1, s. 32-42

Tidskriftsartikel (refereegranskat)abstract
- The 15 areas under study in the WHO/Euro Multicentre Study on Parasuicide vary considerably with regard to socio-economic factors, culture, life-styles, etc. In this paper, the authors discuss whether the traditional high risk factors for suicidal behavior (such as unemployment, abuse, divorce, etc.) take on different weights depending on local societal and cultural settings. Results from analyzing covariations between various background factors characteristic of the different areas under study and the frequency of attempted suicide showed weak or insignificant correlations, indicating that high-risk factors can only be identified from international pooled data with great care.
