This document has been developed to provide a practical guide for the application of speckle tracking echocardiography (STE) in paediatric and congenital heart diseases. In the present document, the following topics are reviewed and discussed: (i) the basic principles of STE, its potential applications, and limitations in the paediatric population; (ii) normal paediatric reference values for STE;
Prospective evidence linking early-life microbiome development and host genetics with type 1 diabetes (T1D) risk is limited. Here, we describe how gut microbiome maturation and host genetics influence T1D risk in the TEDDY study. We analysed 12,151 longitudinal metagenomes and host genetic data from 887 children at high genetic risk for T1D followed for up to 6 years. We identify three microbiome
Identifying phylogeographic breaks and deciphering the relative contributions of environmental extrinsic (e.g., geological barriers, ecological gradients) and organismal intrinsic (e.g., limited dispersal, reproductive incompatibilities) factors to their persistence remain challenging, especially in the absence of genomic data. Here, we address this issue using parapatric lineages of the lizard Ac
National and international extinction threat assessments provide critical data for research and conservation. Yet, many taxa remain unassessed due to the intensive data requirements of manual evaluations. For example, in Sweden, fewer than 40 % of known fungal species have an assigned extinction risk in the national Red List. To address this, approximation methods have emerged to provide estimates
The Pelophylax genus comprises two main hybridogenetic systems resulting from hybridization between Pelophylax ridibundus and other species: the P. lessonae-esculentus (LE) system and the P. perezi-grafi (PG) system, whose distribution ranges lie partly (LE) or entirely (PG) outside the natural distribution of P. ridibundus. The introductions and subsequent expansions of P. ridibundus in many area
Digitala medier har blivit en självklar del i många människors vardag, och för med sig många möjligheter. Samtidigt riskerar en hög användning att tränga undan aktiviteter som är viktiga för människans välmående. Detta examensarbete undersöker hur den byggda miljön kan fungera som ett komplement och en motvikt till en allt mer digital vardag. Arbetet utgår från tankar om digital minimalism och beDigital media has become a natural part of many people’s everyday lives, which brings many opportunities. At the same time, high usage risks displacing activities that are important for human wellbeing. This thesis investigates how the built environment can function as a complement and counterbalance to an increasingly digital everyday life. The project is based on ideas about digital minimalism
Mangrove phenology reflects seasonal changes in canopy development and ecosystem activity, but satellite-based monitoring remains challenging because mangroves are evergreen and occur in intertidal environments where changing water backgrounds may affect vegetation signals. This study evaluated the performance of the Normalized Difference Vegetation Index (NDVI), two-band Enhanced Vegetation Index
På samma sätt som det är naturligt för ungdomar från bruksorter att flytta till Stockholm bör Stockholmsungdomar ställa in sig på att flytta ut från stan, skriver Ingemar Bengtsson, universitetslektor i fastighetsvetenskap vid Lunds universitet.
Med utgångspunkt i Johan Asplunds teori om social responsivitet undersöker texten betydelsen av att människor och andra levande varelser svarar på varandra – och vad som kan hända när gensvaret uteblir. Genom exempel som sträcker sig från berättelser om så kallade vargbarn till relationen mellan människa och hund diskuteras social responsivitet som en del av den process genom vilken vi formas som
In this article, it is shown that Koebe inner functions and squares of singular Nevanlinna functions, so called atomic density functions, have minimal realizations in reproducing kernel Krein spaces.
This thesis examines if long term changes in Solar Zenith Angle (SZA) affects the Normalized Difference Vegetation Index (NDVI), from the Pathfinder land data set, for data taken from the Sahel region in Africa during 1982 to 2000. Both cointegration and ordinary least squares regression of NDVI onto SZA and additional explanatory variables are used in the analysis. Further simple deterministic mo
Realistic depictions of past land cover are needed to investigate prehistoric environmental changes, effects of anthropogenic deforestation, and long term land cover-climate feedbacks. Observation based reconstructions of past land cover are rare and commonly used model based reconstructions exhibit considerable differences. Recently \citet[Spatial Statistics, 24:14--31,][]{PirzaLPG2018_24} develo
Atmospheric inverse modelling is a method for reconstructing historical fluxes of green-house gas between land and atmosphere, using observed atmospheric concentrations and an atmospheric tracer transport model. The small number of observed atmospheric concentrations in relation to the number of unknown flux components makes the inverse problem ill-conditioned, and assumptions on the fluxes are ne
