A Sparsity-Based Passive Multistatic Detector

In this paper, we examine the problem of target detection for the multistatic passive radar. Passive radar systems leverage the existing wireless sources, such as radio/TV stations and cellular signals that are referred to as illuminators of opportunity (IOs), to illuminate the environment and provide surveillance functions. Usually, these IO source signals are sparse or locally sparse in the freq

Clinical outcome of the 2nd generation cryoballoon for pulmonary vein isolation in patients with persistent atrial fibrillation - A sub-study of the randomized trial evaluating single versus dual cryoballoon applications

AIMS: To assess the efficacy of the 2nd generation Cryoballoon for pulmonary vein isolation (PVI) in patients with persistent atrial fibrillation (PersAF), and to compare it to patients with paroxysmal atrial fibrillation (PAF).METHODS: The outcome (arrhythmia recurrence at 12 months) was prospectively assessed in patients with PersAF(n = 77) and compared to that in patients with PAF(n = 62), who

Acute and long-term efficacy and safety with a single cryoballoon application as compared with the standard dual application strategy : a prospective randomized study using the second-generation cryoballoon for pulmonary vein isolation in patients with symptomatic atrial fibrillation

Aims: A single cryoballoon (CB) application per vein for pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF) could save time and was therefore compared to the standard approach of two consecutive CB applications for acute and long-term efficacy and safety.Methods and results: Patients with symptomatic AF were randomized to a single CB application per vein guided by an Achieve®

Increase of ventricular interval during atrial fibrillation by atrioventricular node vagal stimulation : chronic clinical atrioventricular-nodal stimulation download study

BACKGROUND: Patients with a high ventricular rate during atrial fibrillation (AF) are at increased risk of receiving inappropriate implantable cardioverter defibrillator shocks. The objective was to demonstrate the feasibility of high frequency atrioventricular-nodal stimulation (AVNS) to reduce the ventricular rate during AF to prevent inappropriate implantable cardioverter defibrillator shocks.M

Outcomes and safety of new techniques for pulmonary vein isolation in patients with paroxysmal and persistent atrial fibrillation: A study based on randomised trials and registries

Atrial fibrillation (AF) is a common disease with a high prevalence in the adult population. Treatment of AF encompasses antiarrhythmic drugs and catheter ablation to reduce symptoms. The aim of this thesis was to study how to best alleviate symptoms of AF in a safe and efficient way comparing pharmacological treatment and the two dominating catheter ablation techniques, cryoballoon (CRYO) ablatio

Markers of inflammation, endothelial activation, and arterial stiffness in hypertensive heart disease and the effects of treatment : results from the SILVHIA study

We assessed the contribution of blood pressure (BP), inflammation, and endothelial activation to the development of structural vascular and cardiac changes in hypertension. Furthermore, the effects of antihypertensive therapy were studied. We studied 114 patients with hypertension and left ventricular hypertrophy and 38 matched hypertensive subjects without cardiac hypertrophy and 38 normotensive

Permanent pacemaker implantation early and late after heart transplantation : clinical indication, risk factors and prognostic implications

BACKGROUND: Permanent pacemaker implantation (PPM) early after cardiac transplantation has been shown not to predict a worse outcome. However, the requirement for pacing late after transplantation and its prognostic implications are not fully known. We describe the clinical indications, risk factors and long-term outcome in patients who required pacing early and late after transplantation.METHODS:

The Morality of Transparency; Clarity versus Emptiness

With transparency being either a state of clarity or the exposure emptiness, this paper focuses on the practices of transparency, termed ‘transparenting’. Focus on transparenting practices can provide a better tool for understanding the ‘rise of transparency’, and its moral, practical and political aspects. Three types of transparenting are defined: the voluntary transparenting conducted by organi

Variation in wing length in relation to sex and age of marsh tits Parus palustris

Males of both juveniles and adults had significantly longer wings than females, the difference between the sexes being c5.5%. Using wing length as the only criterion, between 97.4% and 88.6% of juveniles and between 98.0% and 93.4% of adults can be unambiguously sexed during autumn/winter. Individuals measured during their second or later autumn/winter had significantly longer wings than those mea
