Integrated chronic care management for patients with atrial fibrillation : a rationale for redesigning atrial fibrillation care
Atrial Fibrillation (AF) is a highly prevalent heart rhythm disturbance, often associated with underlying (cardio)vascular disease. Due to this the management of AF is often complex and current practice calls for a more comprehensive, multifactorial and patient-centred approach. Therefore an Integrated Chronic Care approach in AF was developed and implemented in terms of a nurse-led specialized outpatient clinic for patients with AF. A randomised controlled trial comparing the nurse-led approach with usual care demonstrated superiority in terms of cardiovascular hospitalization and death as well as cost-effectiveness in terms of Quality Adjusted Life Years (QALYs) and life years, in favour of the nurse-led approach. Implementing such approach can be difficult since daily practice can be persistent. To highlight the importance of integrated care wherein the nurse fulfils a significant role, and to provide a guide in developing and continuing such approach, this paper presents the theoretical framework of the AF-Clinic based on the principles of the Taxonomy for Integrated Chronic Atrial Fibrillation Management.Jeroen M L Hendriks, Harry J G M Crijns, Hubertus J M Vrijhoe

Performance analysis of linear optical amplifiers in dynamic WDM systems
We demonstrate the performance of linear optical amplifiers (LOAs) in a dynamic and reconfigurable wavelength-division-multiplexing (WDM) system. Eight WDM channels, each channel running at 10 Gb/s, are transmitted through two cascaded LOAs. Power transient immune add-drop capability is demonstrated by switching four of the eight channels at rates of 10-100 kHz without affecting the bit-error-rate (BER) or eye pattern. The same WDM system trial using erbium-doped fiber amplifiers instead of LOAs shows identical BER performance for the eight-channel case, but deteriorated eye patterns and bit error penalties for the channel ADD-DROP configuration
Stochastic series expansion method for quantum Ising models with arbitrary interactions
A quantum Monte Carlo algorithm for the transverse Ising model with arbitrary
short- or long-range interactions is presented. The algorithm is based on
sampling the diagonal matrix elements of the power series expansion of the
density matrix (stochastic series expansion), and avoids the interaction
summations necessary in conventional methods. In the case of long-range
interactions, the scaling of the computation time with the system size N is
therefore reduced from N^2 to Nln(N). The method is tested on a one-dimensional
ferromagnet in a transverse field, with interactions decaying as 1/r^2.Comment: 9 pages, 5 figure
