Aliasing gives a lower bound for the sampling rate in ordinary spectral analysis of a time series. In parametric it appears at first sight that no such limitations are present. In this note we will obtain insight into this paradox by analyzing a simple Gauss-Markov process. We assume that a time series analysis is performed based on N samples of the series at equal spacing h. The result shows that

In this article, results from a series of studies on the relationships between socioeconomic factors and stroke processes (stroke unit care, acute reperfusion treatment, secondary prevention with oral anticoagulants and statins) and outcomes (long-term survival, return to work and risk of suicide and suicide attempts) are summarized. The overall pattern is that acute and secondary prevention inter

Acta Neurol Scand: 2011: 123: 424-429. © 2010 John Wiley & Sons A/S. Background - No previous study prospectively investigated the effects of subthalamic deep brain stimulation on fear of falling (FOF) and falls. Aim - The aim was to p

Intrastriatal grafts of stem cell-derived dopamine (DA) neurons induce behavioral recovery in animal models of Parkinson's disease (PD), but how they functionally integrate in host neural circuitries is poorly understood. Here, Wnt5a-overexpressing neural stem cells derived from embryonic ventral mesencephalon of tyrosine hydroxylase-GFP transgenic mice were expanded as neurospheres and transplant

Objective: An intervention to structure patient-key worker communication has been tested in a randomized controlled trial. The aim of this paper was to investigate effectiveness of the intervention in terms of moderators of effectiveness. Method: A total of 507 patients with schizophrenia were included. Moderators of effectiveness were investigated using two-way anovas. Results: Patients with a be

OBJECTIVES: To assess the human complement inhibitor C4b-binding protein (C4BP) for treatment of arthritis. METHODS: We have used two mouse models of rheumatoid arthritis (RA) to assess the therapeutic effect of C4BP on different phases of arthritis, the collagen antibody induced arthritis (CAIA), an acute antibody induced disease and the collagen induced arthritis (CIA), which carries the full co

The influence of sorption of bacteria, as well as 2,4-dichlorophenol (2,4-DCP), on the mineralization of 100 microg l(-1) of the organic compound was examined in an aquifer material under advective flow conditions (column displacement technique). The study was designed to distinguish the rates and extent of biodegradation of the sorbed and the dissolved trace organic and the contribution of sorbed
