In this paper, a fully automatic method for the diagnosis of pulmonary embolism (PE) from V/Q-scans is presented. Image analysis is applied to the ventilation and the perfusion images obtained in the V/Q-scan. The difference of the ventilation and the perfusion is calculated after transformation and hot-spot reduction of the images. From this difference image the integral of the underperfused area
An academic 12-lead electrocardiogram (ECG) core laboratory aims to provide the highest possible quality ECG recording, measurement, and storage to aid clinicians in research into important cardiovascular outcomes and to maximize the credibility of scientific results based solely, or in part, on ECG data. This position paper presents a guide for the structure and function of an academic ECG core l
This article sets out to describe and explain the events that led, in the summer of 1967, to political chaos and near civil war in many parts of China. It links the violence on the ground to statements and policies formulated at the highest levels of the CCP and sets out to show how and why Mao Zedong himself must bear direct personal responsibility for what stands out as one of the darkest chapte
A novel method for the synthesis of spherical molecularly imprinted polymer (MIP) beads by suspension polymerization in mineral oil is described. The usefulness of the method was demonstrated by the synthesis of a propranolol imprinted MIP library. The composition of the library was generated by statistical experimental design. Multivariate data analysis correlated the screening data, obtained by
In this study the elasto-plastic constitutive equations are reformulated using the assumption of constant strain rate direction within a load increment. This assumption allows the constitutive evolution laws to be rewritten as ordinary differential equations (ODEs). The set of ODEs is reduced using the Krieg and Krieg description of the deviatoric stress space. Although this approach does generall
Living with dementia means struggling to preserve a sense of self, to retain (and reevaluate) one's values in a new situation, and to search for a new way of life. This study explored the meaning of everyday life as expressed by 11 people suffering from dementia. Data were collected through interviews with people in the early stage of a diagnosed dementia disease. The findings indicate that many p
Two different self-adjoint Pauli extensions describing a spin-1/2 two-dimensional quantum system with singular magnetic field are studied. An Aharonov-Casher type formula is proved for the maximal Pauli extension and the possibility of approximation of the two different self-adjoint extensions by operators with regular magnetic fields is investigated.
The aim of this study was to investigate the specificity of the H-3-triolein assay and to investigate the recovery of highly purified pancreatic lipase and pancreatic lipase in the form of pure non-activated pig pancreatic juice. Blood plasma from pigs was analysed for pancreatic lipase activity using the H-3-triolein substrate assay, with a method specific for lipoprotein lipase and with a method
Wireless Personal Area Networks (WPAN) has gained interest in the last few years and several air interfaces have been proposed to cover WPAN applications. A Multi-Carrier Spread Spectrum (MC-SS) air interface specified to achieve 130 Mbps in typical WPAN channels, is presented in this paper. It operates in the 5.2 GHz ISM band and achieves a spectral efficiency of 3.25 b.s-1.Hz-1. Besides the robu
We report on a large scale calculation concerning the 5s(2) S-1 and 5s5p P-1,P-3 levels in Sr-88 I, using multiconfiguration Dirac-Fock methods. Our focus is on the P-3(2) meta-stable level, which has been shown to be extremely useful in atom cooling and trapping experiments. The lifetime for this level from our work (1071 s) agrees very well with a previous theoretical value, but not with the ava
Antibody-based microarrays is a rapidly evolving technology that has gone from the first proof-of-concept studies to more demanding proteome profiling applications, during the last years. Miniaturized microarrays can be printed with large number of antibodies harbouring predetermined specificities, capable of targeting high- as well as low-abundant analytes in complex, nonfractionated proteomes. C
Participation is about finding consensus in diversity and reflects a normative shift towards multiple-use values that recognise that forest management should blend multiple management objectives into a coherent set of practices. A framework to incorporate interest groups' values and needs into functional forest management systems has yet to be institutionalised in contemporary forest policy and ma
When planning new environments, such as homes and workplaces, for the physically disabled it is important to encourage active participation from all those involved. In a research programme initiated at the Lund Institute of Technology, Sweden, a new planning method is being introduced which utilizes computer-aided design as a planning tool. This tool supports and activates the understanding and pa
We consider the effect of symbol rate on the constrained capacity of linear modulation with a fixed spectral density. We show that constrained capacity grows with the symbol rate for some modulation pulses but shrinks with others. Sufficient conditions on the pulse are derived for the constrained capacity to be monotonically increasing with faster symbol rate. Most standard pulses fulfill these.
Purpose of this paper
The purpose is twofold: to map the reviewers’ perspective of evaluation of case based logistics and supply chain management research; and to develop a framework with all criteria needed to design, conduct, and present rigorous case study research. This framework can be used by both researchers and reviewers.

We discuss the IAU resolutions B1.3, B1.4, B1.5, and B1.9 that wereadopted during the 24th General Assembly in Manchester, 2000, andprovides details on and explanations for these resolutions. It isexplained why they present significant progress over the correspondingIAU 1991 resolutions and why they are necessary in the light of presentaccuracies in astrometry, celestial mechanics, and metrology.
