  • Cognition-enhancing effect of vagus nerve stimulation in patients with Alzheimer's disease: a pilot study.
  • 2002
  • Ingår i: The Journal of clinical psychiatry. - 0160-6689. ; 63:11, s. 972-80
  • Tidskriftsartikel (refereegranskat)abstract
    • Vagus nerve stimulation (VNS) is an established treatment method for therapy-refractory epilepsy and, in Europe, for treatment-resistant depression also. Clinical and experimental investigations have also shown positive effects of VNS on cognition in epilepsy and depression. The purpose of the present pilot study was to investigate the effect of VNS on cognition in patients with Alzheimer's disease.

  • Exergianalys som verktyg inom VA-tekniken
  • 2003
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Exergianalys är ett värderingssätt som ger ett mått på förbrukning av ordnade strukturer och kan ses som ett komplement till ekonomiska analyser. Exergianalysen kräver en klar avgränsning av det system som ska utvärderas. I denna rapport ges tre exempel på hur exergikalkyler kan nyttjas i VA-sammanhang. Slutligen diskuteras exergikalkylernas begränsningar och möjligheter

  • Third-order dispersion compensation using a phase modulator
  • 2003
  • Ingår i: Journal of Lightwave Technology. - 0733-8724 .- 1558-2213. ; 20:5, s. 1188-1197
  • Tidskriftsartikel (refereegranskat)abstract
    • Compensation of third-order dispersion in a fiber-optic transmission system using a phase modulator is studied both theoretically and experimentally. A sinusoidal signal is used as modulation function, where the amplitude and phase delay are optimized. The 2-ps input pulses (160-Gb/s compatible) were transmitted through a 626-km fiber link, where the characteristic oscillating tail was measured with a 1.6-ps resolution optical sampling system. When applying the phase modulation, the oscillating tail was significantly suppressed. The pulses were also used in a 160-Gb/s transmission experiment, where the eye diagrams were measured with the sampling system. Numerical simulations and practical experiments showed excellent agreement.

  • Evaluation of screening procedures for congenital cataracts.
  • 2003
  • Ingår i: Acta paediatrica (Oslo, Norway : 1992). - : Wiley. - 0803-5253 .- 1651-2227. ; 92:12, s. 1468-73
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM: To evaluate the efficacy of two different Swedish screening procedures for early detection of congenital cataracts in comparison with no screening. METHODS: Children born between January 1992 and December 1998 in Swedish regions with an established eye-screening routine procedure, diagnosed with congenital cataract, and operated on before 1 y of age, were included in a retrospective study. Age at referral and age at time of the operation were compared between regions using different screening procedures: screening in the maternity wards (Region 1), at the well-baby clinics (Region 2) and one region without any screening (Region 3). RESULTS: Seventy-two children were included in the study. Concerning early diagnosis and surgery, Region 1 differed significantly from Regions 2 and 3, which were more similar and were combined for further analysis. The difference in detected cases was greatest at 21 d of age (55% vs 18%; p < 0.001), but persisted even at 100 d of age (78% vs 64%; p < 0.02). Region 1 screening resulted in more and earlier cases detected than the other two regions (22 vs 15 per 100,000 births). In 72% of all cases, surgery was performed in response to referrals from either the maternity wards (36%), or the well-baby clinics (36%). However, half of the cases from the well-baby clinics were detected too late, i.e. at > 100 d. CONCLUSION: Eye screening in the maternity ward is preferable to well-baby clinic screening and to no screening at all, since it leads to early detection. Screening should also be performed routinely at well-baby clinics within the period when successful treatment is possible.
