We investigated the formation of an abstract concept of same/different in a harbor seal by means of a two-item same/different task. Stimuli were presented on a TFT monitor. The subject was trained to respond according to whether two horizontally aligned white shapes presented on a black background were the same, or different from each other, by giving a no-go or go response. Training comprised of
Spectral estimation is an important classical problem that has received considerable attention in the signal processing literature. In this contribution, we propose a novel method for estimating the parameters of sums of complex exponentials embedded in additive noise from regularly or irregularly spaced samples. The method relies on Kronecker's theorem for Hankel operators, which enables us to fo
In a recent study combining transcriptome analyses of a number of recombinant laboratory and industrial S. cerevisiae strains with improved xylose utilization and their respective control strains, the ORF YLR042c was identified as a downregulated gene and it was shown that the gene deletion improved aerobic growth on xylose in the tested strain background. In the present study, the influence of de
Chromosomal translocations play a crucial role in tumorigenesis, often resulting in the formation of chimeric genes or in gene deregulation through position effects. T-cell acute lymphoblastic leukemia (T-ALL) is associated with a large number of such rearrangements. We report the ectopic expression of the 3' portion of EST DA926692 in the bone marrow of a childhood T-ALL case showing a t(2;11)(q1
Solution and adsorption properties of both charged and uncharged bottle-brush polymers have been investigated. The solution conformation and interactions in solution have been investigated by small-angle scattering techniques. The association of the bottle-brush polymers with anionic surfactants has also been studied. Surfactant binding isotherm measurements, NMR, surface tension measurements, as
The productivity of agricultural and forest ecosystems in regions at higher latitudes is to a large extent governed by low temperature and moisture conditions. Environmental conditions are acting both above- and below-ground and regulating carbon fluxes and evapotranspiration. However, the understanding of various feedbacks between vegetation and environmental conditions is still unclear. In this
Objective. The prevalence of anemia in inflammatory bowel disease (IBD) has been broadly described. The recurrence, type and burden of anemia remain unenlightened. The primary objective was to describe this. The secondary objective was to evaluate the implementation of European guidelines. Materials and methods. This longitudinal follow-up study included 300 IBD outpatients from six centers in Sca
Background It might be that early intestinal colonization by bacteria in westernized infants fails to give rise to sufficient immune stimulation to support maturation of regulatory immune mechanisms. Objective The purpose of the present study was to characterize the very early infantile microbiota by using a culture-independent approach and to relate the colonization pattern to development of at
Background: Conventional radiography is insufficient for diagnosis in a small but not unimportant number of hip fractures, and secondary imaging with computed tomography (CT) or magnetic resonance imaging (MRI) is warranted. There are no convincing observer variation studies performed for conventional radiography or CT in occult fractures, and no large materials for MRI. Purpose: To assess observe
Understanding the spatiotemporal distribution of birds is crucial for effective management and conservation of their populations. However, we still have only limited knowledge not only of the wintering destinations of many Iberian breeding migrants but also of aspects as general as the migratory behaviour of the populations of many common avian species that breed in the Iberian highlands. We used
BACKGROUND: Interventions aimed at reducing the number of smokers are generally believed to be cost effective. However as the cost of the interventions should be paid up front whereas the gains in life years only appear in the future--the budgetary consequences might be a barrier to implementing such interventions. AIMS: The aim of the present paper was to assess the long-term cost effectiveness
Fed aquaculture is a necessary practice to meet the seafood requirements of a growing population in a sustainable manner. There is a high demand for fish feed to meet the rising protein requirements of the industry. Currently, fish feeds are either unsustainable, affected by seasonal variations, lack a complete amino acid profile, lack scalability, or are too expensive. Single Cell Protein (SCP) i
The aggregation of amyloid β in the brain is considered to be the main cause of the currently incurable Alzheimer’s disease. Research investigating fibrils is being conducted continuously. Despite this, there is an incredibly large knowledge gap in what we know about the aggregation process. This study aims to investigate the temperature influence on the Aβ40 aggregation process using differential
During the last decades there has been an increase of the housing segregation in Sweden. According to research this is mainly due to greater economic inequality and increased immigration. In Sweden there are a number of neighbourhoods with low socioeconomic standards that are mostly inhabited by immigrants, in these areas women are a particularly vulnerable group. Research states that learning the
Antagandet om att personer med ätstörningar är smala är fortfarande utbrett, trots att det finns ett signifikant samband mellan ätstörningar och obesitas. I linje med detta finns en kunskapslucka avseende skattningsformulär riktade mot att fånga ätstörningar och subkliniska besvär hos personer med obesitas. En systematisk litteraturöversikt genomfördes med syftet att hitta tillgängliga formulär, mThe assumption that people with eating disorders are skinny is still widespread, even though there is a co-occurrence between eating disorders and obesity. Despite this co-occurrence, there is a gap in the knowledge regarding questionnaires aimed at assessing eating disorders and subclinical symptoms for people with obesity. Therefore, a systematic review was conducted with the purpose of finding
Galaxies contain a wide variety of star clusters with different properties. Each cluster is a possible source of runaway stars, which can be progenitors of supernovae in other parts of the galaxy than their home cluster. Considering runaway stars in galaxy simulations has shown to increase the galactic feedback. This project investigates how the initial condition of a star cluster affects the velo
The purpose of this study is to examine digital information loss at three Swedish archives. Digital preservation is a complex issue and something most archival institutions struggle with today. While there is merit in focussing on successes in this struggle, doing so to the exclusion of failures runs the risk of creating a blind spot for existing problems. We hope that this study will contribute t
The possibility to have a strongly first order electroweak phase transition, which is one of the Sakharov conditions for electroweak baryogenesis together with $\mathcal{CP}$ violation and baryon number violation, in general Two-Higgs-Doublet Models (2HDMs) is here investigated. Different kinds of $\mathbb{Z}_{2}$ breaking beyond standard assumptions are studied, in particular by allowing it to be
