In this article we want to introduce first the Gabor wavelet network as a model based approach for an effective and efficient object representation. The Gabor wavelet network has several advantages such as invariance to some degree with respect to translation, rotation and dilation. Furthermore, the use of Gabor filters ensured that geometrical and textural object features are encoded. The feasibi
In this article we present a method for visual face tracking that is based on a wavelet representation of a face template. The wavelet representation allows arbitrary affine deformations of the facial image, it allows to generalize from an individual face template to a rather general face template and it allows to adapt the computational needs of the tracking algorithm to the computational resourc

Purpose: Elevated cardiac troponin levels have been shown to be associated with a poor prognosis under some intensive care conditions. This study investigated whether inclusion of high-sensitivity troponin T (hsTnT) increased the prognostic accuracy of the Simplified Acute Physiology Score (SAPS 3) for general intensive care unit (ICU) patients, cardiac arrest patients, or patients with a non-card
The sustainability transformation calls for policies that consider the global consequences of local lifestyles. We used stakeholders' visions of sustainable lifestyles across Europe to build 19 scenarios of sufficiency (net reductions) and 17 of green consumption (shift in consumption patterns). We applied Environmentally Extended Multi-Regional Input-Output analysis to model scenarios by assuming
Different dietary sources of bioactives may reduce cardiometabolic risk. This work investigated the feasibility of using a high-fat/high-caloric meal challenge as a tool for assessing the cardiometabolic protective effects of three bioactive-rich foods. Thirteen healthy, but overweight volunteers (65.1 ± 5.3 years old, fasting glycemia, ≤6.1 mmol L−1) received a high-fat reference breakfast meal (
Background: Idiopathic ventricular fibrillation (IVF) is a rare cause of sudden cardiac arrest which may pose therapeutic and prognostic challenges. To date, the only effective treatment for survivors of cardiac arrest is the insertion of an implantable cardioverter-defibrillator (ICD). We sought to review the long-term outcome of a Swedish cohort with IVF. Methods and results: Fifty patients with
Standard interpolation techniques are implicitly based on the assumption that the signal lies on a single homogeneous domain. In contrast, many naturally occurring signals lie on an inhomogeneous domain, such as brain activity associated to different brain tissue. We propose an interpolation method that instead exploits prior information about domain inhomogeneity, characterized by different, pote
Aims: Adaptation to low oxygen of hematopoietic stem cells (HSCs) in the bone marrow has been demonstrated to depend on the activation of hypoxia-inducible factor (HIF)-1α as well as the limited production of reactive oxygen species (ROS). In this study, we aimed at determining whether HIF-1α is involved in protecting HSCs from ROS. Results: Oxidative stress was induced by DL-buthionine-(S,R)-sulf
Converting resident glia in the brain into functional and subtype-specific neurons in vivo provides a step forward towards the development of alternative cell replacement therapies while also creating tools to study cell fate in situ. To date, it has been possible to obtain neurons via in vivo reprogramming, but the precise phenotype of these neurons or how they mature has not been analyzed in det
Syfte: I denna kvalitativa studie studerade vi erfarenheter bland familjemedlemmar till cancerpatienter. Vårt syfte var att undersöka och differentiera deras behov från de behov som cancer patienten uppvisar.Metod: Fem fokusintervjuer och sex individuella narrativa intervjuer med 17 familje medlemmar till cancerpatiener i Sverige genomfördes och jämförda med 19 intervjuer med cancerpatienter. Vår
I detta kapitel är syftet att ha fokus på yngre barn, det vill säga 0-12-åringar. I uppgiften att förstå sig på yngre barn ingår att ta i beaktande skillnader i utvecklingsnivå och behov hos spädbarn, förskolebarn och yngre skolbarn. Teoretiska perspektiv från utvecklingspsykologi, barndomssociologi, utvecklingspsykopatologi och utvecklingsekologi är användbara i detta sammanhang. Att se individen
”Nationalism och nazism i parnassens marginal” handlar om svensk politisk poesi och kampsång som publicerades i den nationalistiska och nazistiska pressen i Sverige under 1930- och 1940-talen för att ge inspiration och uppbyggelse i den politiska kampen.“Nationalism and Nazism at the margins of the Parnassus” deals with Swedish political poetry and fight songs that were published in the Nationalistic and Nazi press in Sweden during the 1930s and 1940s in order to inspire and edify the political struggle.
We provide a counterexample to the Sarason Conjecture for the Bergman space and present a characterisation of bounded Toeplitz products on the Bergman space in terms of test functions by means of a dyadic model approach. We also present some results about two-weighted estimates for the Bergman projection. Finally, we introduce the class B∞ and give sharp estimates for the one-weighted Bergman proj
This article reviews the recent developments on the boudedness of products of Toeplitz operators. Special attention is paid to the solution of a conjecture posted by D. Sarason in the 90’s on the product of Toeplitz operators in the Bergman space recently achieved by Aleman, Pott and the author in [1].
