AIM: The aim of this retrospective study is to illustrate clinical utility and impact of pulmonary embolism (PE) diagnostics of up to date Ventilation/Perfusion SPECT (V/P (SPECT)) applying holistic interpretation criteria. MATERIAL AND METHODS: During a 2-year period 2328 consecutive patients referred to V/P(SPECT) for clinically suspected PE were examined. Final diagnosis was established by phys
In this paper I discuss how a virtue ethic for the preservation of biodiversity may look like. The starting-point is the virtue ethic proposed by Celia Deane-Drummond. She suggests that the four cardinal virtues of prudence, justice, fortitude and temperance should form the basis of an ethic of nature. Of this four, prudence is the most fundamental. Moreover, Deane-Drummond states that the intelle
Thrombin generation is a key process that determines the extent of a hemostatic plug or a thrombotic process. The ensuing thrombin burst is crucial for the formation of a stable fibrin clot. During its active life, thrombin exerts a multitude of highly regulated actions on the blood and the vessel wall, among which is the clotting of fibrinogen. The inappropriate generation of thrombin may lead to
Popular Abstract in Swedish Diabetes är en folksjukdom och dess förekomst ökar dramatiskt över hela världen. Typ 2 diabetes, eller åldersdiabetes, är den i särklass vanligaste varianten av diabetes. Typ 2 diabetes är starkt förknippat med övervikt och fetma vilket illustreras av att ca 90 % av alla typ 2 diabetiker är överviktiga. Typ 2 diabetes kan förhindras genom livsstilsförändringar. Många mäThere is currently a dramatic and global increase in obesity, type 2 diabetes (T2D) and associated metabolic disorders. T2D can be delayed or prevented in individuals at risk and identifying and developing new food concepts for the prevention of obesity and T2D is of utmost importance. This thesis describes our work on exploring new food concepts for the prevention of T2D. We have used 3T3-L1 adip
Current international guidelines recommend cerebral computerized tomography (CT) before lumbar puncture (LP) in many adults with suspected acute bacterial meningitis (ABM), due to concern about LP-induced cerebral herniation. Despite guideline emphasis on early treatment based on symptoms, performing CT prior to LP implies a risk of delayed ABM treatment, which may be associated with a fatal outco
Many studies have been made on the impact of supplemental instruction in supported courses, most show significantly better examination results for students attending supplemental instruction in comparison to those who do not. However, remarkably little attention has been devoted to following up whether the benefits of supplemental instruction reach beyond the course it supports. The present study
Is the real problem in finding the relative orientation of two viewpoints the correspondence problem? We argue that this is only one difficulty. Even with known correspondences, popular methods like the eight point algorithm and minimal solvers may break down due to planar scenes or small relative motions. In this paper, we derive a simple, brute-force algorithm which is both robust to outliers an
A tool has been developed which can be used to evaluate human gait in a more detailed manner. Its purpose is to record data from an individual during gait then categorize and analyze the intrinsic phases with neuro-fuzzy techni(TRUNCATED)
Popular Abstract in Swedish Standard-12-avlednings-EKG är fortfarande ett av de viktigaste och vanligaste redskapen för att diagnostisera hjärtsjukdom trots att ett flertal olika undersökningstekniker har utvecklats under åren. Vid standard-EKG används 10 elektroder, 6 på bröstkorgen och 4 distalt på armar och ben. Inom både industrin och akademin har många års arbete lagts ned på utveckling av deThe standard 12-lead electrocardiogram (ECG) remains one of the most important and most frequently used tools for diagnosing cardiac diseases, although several different examination modalities in cardio¬logy have been developed over the years. The standard ECG uses 10 electrodes placed on well-defined positions on the body, 6 on the torso and 4 distally on the limbs. Both industry and academia hav
Protection against mucosally transmitted infections probably requires immunity at the site of pathogen entry(1), yet there are no mucosal adjuvant formulations licensed for human use. Polyethyleneimine (PEI) represents a family of organic polycations used as nucleic acid transfection reagents in vitro and DNA vaccine delivery vehicles in vivo(2,3). Here we show that diverse PEI forms have potent m
Purpose - The purpose of this paper is to develop an approach for investigating the impact of surveillance technologies used to facilitate security and its effect upon privacy. Design/methodology/approach - The authors develop a methodology by drawing on an isomorphy of concepts from the discipline of Macroeconomics. This proposal is achieved by considering security and privacy as economic goods,
The spatial resolution of fluorescence molecular imaging is a critical issue for the success of the technique in biomedical applications. One important method for increasing the imaging resolution is to utilize multi-photon emissions. In this study, we thoroughly investigate the potential of the multi-photon upconversion emissions from rare-earth-doped upconverting nanoparticles for the improvemen
We consider model predictive control (MPC) problems with linear dynamics, polytopic constraints, and quadratic objective. The resulting optimization problem is solved by applying an accelerated gradient method to the dual problem. The focus of this paper is to provide bounds on the number of iterations needed in the algorithm to guarantee a prespecified accuracy of the dual function value and the
Adaptive reservation is a real-time scheduling technique in which each application is associated a fraction of the computational resource (a reservation) that can be dynamically adapted to the varying requirements of the application by using appropriate feedback control algorithms. An adaptive reservation is typically implemented by using an aperiodic server (e.g. sporadic server) algorithm with f
In osteoblasts, cyclooxygenase 2 (COX-2) is the major isozyme responsible for production of prostaglandins. Prostaglandins are local mediators of bone resorption and formation and are known to be involved in bone's adaptive response to fluid shear stress (FSS). We have previously described a model of trabecular bone loss in hindlimb-suspended mice and rats and demonstrated partial protection from
We propose a simple modification of the famous Bahl-Cocke-Jelinek-Raviv (BCJR) algorithm for linear block codes. The modified algorithm requires one forward and two backward recursions in the code trellis, but eliminates the need to store the whole trellis. Compared with the BCJR algorithm, the computational complexity is slightly increased, but the storage requirement is reduced.
A new method for collection of group data is described— Group Diary. Document studies in psychology are a background. Group members collect data as recorders and synthesize their notes. The method is a tool for learning, research and consultation. Methodological issues are elucidated. After presentation of five studies on group formation and development done by the authors, the pros and cons of th
We consider transmission by a vector adder channel with two independent inputs and additive white Gaussian noise. Decisions on the channel output are made by individual decoders. A new metric for decoding in such a channel is proposed, which is a generalization of the correlation metric and is close to the optimal metric in some cases. Bounds on decoding error probability are given. A procedure fo
