OBJECTIVE: Obesity is a key risk factor for type 2 diabetes; however, up to 20% of patients are normal weight. Our aim was to identify metabolite patterns reproducibly predictive of BMI and subsequently to test whether lean individuals who carry an obese metabolome are at hidden high risk of obesity-related diseases, such as type 2 diabetes.RESEARCH DESIGN AND METHODS: Levels of 108 metabolites we
Objective: The clinical significance of QT interval adaptation to heart rate changes has been poorly investigated in atrial fibrillation (AF), since QT delineation in the presence of f-waves is challenging. Therefore, the objective of the present study is to investigate new techniques for QT adaptation estimation in permanent AF. Methods: A multilead strategy based on generalized periodic componen
Topology optimization is used to design phononic bandgap materials that are tunable by mechanical deformation. A periodic media is considered, which due to the assumption of length scale separation, allows the dispersion relations to be obtained by analyzing a single unit cell subjected to Floquet–Bloch boundary conditions. A finite macroscopic deformation is applied to the unit cell to affect its
This study aimed to investigate self-reported physical activity levels, perceived body appearance, and body functioning in relation to perceived wellbeing among adolescents. A cross-sectional survey was performed in four upper secondary schools in one municipality in southern Sweden. Data were obtained from questionnaires completed by 1,491 adolescents (55.4% females; median age 16; range 15–17 ye
Background: Internet gaming disorder (IGD) was recently added in the Diagnostic and Statistical Manual of Mental Disorder as a “condition for further studies.” There is no consensus regarding which rating scales should be used but many scholars suggest the GASA (Game Addiction Scale for Adolescents) and a ranking of the criteria, “the core approach” to avoid over-diagnosing of disordered gaming. M
Background: Nerve compression disorders, such as carpal tunnel syndrome (CTS) and ulnar entrapment at the elbow (UNE), may be associated with apoptosis and neuroprotective mechanisms in the peripheral nerve that may be detected by biomarkers in the blood. The relationships between CTS and UNE and two biomarkers of apoptosis, i.e., caspase-3 and caspase-8, and the neuroprotective factor Heat Shock
A detailed investigation of ion channelling and defect production for a highly- ordered array of multi-wall carbon nanotubes is presented. The effects of argon ion bombardment (0.25–5 keV) carried out either parallel (top) or perpendicular (side) to their axis, have been studied by Raman, X-Ray Photoelectron Spectroscopy and Scanning Electron Microscopy. Raman spectra provided evidence of channell
In light of concerns about adolescent mental health, there is a need to identify and examine potential pathways to wellbeing in their daily lives. Outdoor environments can offer multiple pathways to wellbeing through opportunities for restoration, physical activity and socialising. However, urbanisation and new lifestyles revolving around the home and the internet are changing young people’s acces
Introduction: Preparatory motor cortical responses like the lateralized readiness potential (LRP) may be useful in revealing persistent attempts to feign hearing loss. Previous studies suggest only a marginal effect of stimulus intensity on the amplitude of the LRP. However, this has not been investigated using low-intensity auditory stimuli to cue NoGo trials. We address this in an experiment whe
We report on the polarization analysis of the Raman spectrum of highly vertically aligned multiwall carbon nanotubes (MWCNTs). A simple model considering the average angle distribution across the MWCNT axes accounts for the observed angular dependent Raman mode intensity. The model fully fits the experimental data, allowing to derive an average waving angle of ∼37° around the MWCNT axes and explai
It is important to obtain accurate three dimensional structures of molecules and proteins to understand and predict their function and behaviour. X-ray crystallography is the major technique to determine three dimensional structures of proteins. Although there have been major improvements on the experimental side in determining crystallographic data, only small progress has been made on the comput
Background and Aims: There is evidence that housing issues are associated with health outcomes as people age, but little is known in this respect regarding the specific population of people with Parkinson's disease (PD). The objective of this literature review was to identify and analyze the knowledge gap concerning people with PD and housing issues. Methods: Applying established guidelines for sc
The Earth system model EC-Earth3 for contributions to CMIP6 is documented here, with its flexible coupling framework, major model configurations, a methodology for ensuring the simulations are comparable across different high-performance computing (HPC) systems, and with the physical performance of base configurations over the historical period. The variety of possible configurations and sub-model
Efter rättegången mot den folkrättsbrotts- och mordåtalade Hamid Noury kommer Iran att öka sina operationer i Sverige. Prästregimen i Iran bedriver redan ett omfattande flyktingspionage i vårt land, skriver Ardavan Khoshnood, docent, Lunds universitet.Following the trial of Hamid Noury, accused of violations of international law and murder, Iran will increase its operations in Sweden. The clerical regime in Iran is already conducting extensive espionage agianst refugees in our country, writes Ardavan Khoshnood, associate professor, Lund University.
The mixing process in a gas flow plays a crucial role in chemical reactions, and simultaneous measurements of both velocity and mixture fraction are desired to fathom the process. Here, we report a scheme for simultaneously measuring both velocity and concentration by femtosecond laser-induced chemiluminescence. The femtosecond laser would induce chemical reactions that generate CN radicals in the
Objectives: Acquired brain injury (ABI) has long-lasting effects, and patients and their families require continued care andsupport, often for the rest of their lives. For many individuals living with an ABI disorder, nonpharmacologicalrehabilitation treatment care has become increasingly important care component and relevant for informed healthcaredecision making. Our study aimed to appraise econ
This dissertation consists of four independent papers, which share the use of experimental methods. Using different settings – the field, the lab, an online platform, and telephone interviews – I study economic behavior and its underpinning beliefs and preferences.The first paper investigates how an incentive for a hedonic but risky activity affects the risk assessment of young adults. I conduct a
We study the task of embodied visual active learning, where an agent is set to explore a 3d environment with the goal to acquire visual scene understanding by actively selecting views for which to request annotation. While accurate on some benchmarks, today's deep visual recognition pipelines tend to not generalize well in certain real-world scenarios, or for unusual viewpoints. Robotic perception
We focus on the task of estimating a physically plausi-ble articulated human motion from monocular video. Ex-isting approaches that do not consider physics often pro-duce temporally inconsistent output with motion artifacts, while state-of-the-art physics-based approaches have either been shown to work only in controlled laboratory conditions or consider simplified body-ground contact limited to f
