This work aims at studying photoionization dynamics from atoms and surfaces at attose time scales. The work was based on development and applications of a high repetition rate High-order Harmonic Generation (HHG) light source that utilizes Optical Parametric Amplification (OPA) laser technology. The laser system delivers few-cycle pulses in the near infrared (IR) at a repetition rate of 200 kHz.

Observations of polarization position angle (θ) standards made from 2014 to 2023 with the High Precision Polarimetric Instrument (HIPPI) and other HIPPI-class polarimeters in both hemispheres are used to investigate their variability. Multiband data were first used to thoroughly recalibrate the instrument performance by bench-marking against carefully selected literature data. A novel co-ordinate

BACKGROUND: Transient tachypnea of the newborn (TTN) is characterized by tachypnea and signs of respiratory distress. Transient tachypnea typically appears within the first two hours of life in term and late preterm newborns. Supportive management might be sufficient. Non-invasive (i.e. without endotracheal intubation) respiratory support may, however, be administered to reduce respiratory distres

Food can be transformed into data, but it is never only data. This thesis takes the Chinese health and weight management app Boohee as a case study to examine the tension behind its dietary tracking functionality. Rather than evaluating Boohee’ s effectiveness as a health technology, this study frames it as a digital media environment that enables users to record, compare, and self-evaluate dietar

Warnings that the Swedish culture and popular education (folkbildning) infrastructure is under threat due to cutbacks in public funding have recently been highlighted in a joint report published by national interest organizations representing the library and popular education sector. This thesis seeks to explore the role and perceived value of the collaboration between study associations and publi

Background: Over the last decade, computational sciences have contributed immensely to characterization of phenotypes of airway diseases, but it is difficult to compare derived phenotypes across studies, perhaps as a result of the different decisions that fed into these phenotyping exercises. We aim to perform a systematic review of studies using computational approaches to phenotype obstructive a

This report discusses the role of the program coordinator in a faculty where the organisation of connected and integrated courses in bachelor programmes is a fairly new phenomenon. In the Faculties of Humanities and Theology at Lund University there has been a strong tradition to design an individual bachelor exam by combining independent courses. During the last ten years an increasing number of

Climate change and human activities influence the development of ecosystems, with human demand of ecosystem services altering both land use and land cover. Fossil pollen records provide time series of vegetation characteristics, and the aim of this study was to create spatially continuous reconstructions of land cover through the Holocene in southern Sweden. The Landscape Reconstruction Algorithm

The physical boundaries of office work have become increasingly flexible. Work is conducted at multiple locations outside the office, such as at clients’ premises, at home, in cafés, or when traveling. However, the boundary between indoor and outdoor environment seems to be strong and normative regarding how office work is performed. The aim of this study was to explore how office work may be cond

Volume 3 of the FCC Feasibility Report presents studies related to civil engineering, the development of a project implementation scenario, and environmental and sustainability aspects. The report details the iterative improvements made to the civil engineering concepts since 2018, taking into account subsurface conditions, accelerator and experiment requirements, and territorial considerations. I

Populärvetenskaplig sammanfattning: Kvävebelastningen på sjöar och hav har ökat markant de senaste tiotal åren. Jordbruket står för ca 50 % av de svenska kväveutsläppen som människan bidrar till. En ökad kvävebelastning på haven kan leda till övergödning, vilket får en stor negativ effekt på vattenekosystemen. Ett sätt att minska övergödningsproblematiken är att öka vattnets uppehållstid i landska

The current European situation is marked by an ongoing migration crisis. On a daily basis we are informed of the ever-increasing number of migrants trying to reach Europe’s border – too often with fatal results. The European Court ofJustice, once described as “tucked away in the fairyland Duchy ofLuxembourg”, is today faced with difficult legal questions concerning EU asylum law – the present case

IntroductionInjury prevention training is effective in reducing injuries in youth team sports, but public health impact is limited because such training is not widely, properly, or sustainably implemented. Insufficient involvement of end-users has been identified as a main barrier to implementation. Based on results from previous studies within the I-PROTECT project, the aim was to develop a full

Type 1 diabetes, formerly known as juvenile diabetes or insulin-dependent diabetes, results from the specific autoimmune destruction of the pancreatic islet beta cells. The subsequent lack of insulin leads to increased blood and urine glucose. The classical symptoms are polyuria (frequent urination), polydipsia (increased thirst), polyphagia (increased hunger), and weight loss. The disease may be

Mankind has faced a huge increase in severe natural and man-made disasters worldwide in the last few years. Emergency responders on a strategic, tactical, and operational level can be assisted by decision support systems (DSS) to enhance disaster preparedness, response, and recovery. Policy makers are in need of an advanced, resilient and integrated incident command and control systems for emergen

The global aviation industry is experiencing growing pressure to decarbonize, driving significant demand for Sustainable Aviation Fuel (SAF). Second-generation feedstocks that do not directly compete with food crops, such as lipid oils from insects and lignin-derived oils, are promising sources, but their high concentrations of inorganic contaminants and oxygen make them incompatible with existing

Carbon-based materials are highly sought after due to their superior properties, making them valuable for high-performance applications. However, most carbon-based materials are derived from fossil sources, and their synthesis often involves hazardous chemicals. Therefore, it is essential to develop sustainable methods for synthesising these materials from renewable resources, using fewer solvents

In this article, we analyze the reception of the AI-generated poetry collection Ammaseus horisont: AI tolkar Karin Boye (2020) and discuss the more general debate about AI-generated literature in the Swedish press since November 2022, when OpenAI made ChatGPT available to the public. Specifically, we analyze the ways in which Swedish critics construct the literary value of Ammaseus horisont and un

Although many efforts have been made to eliminate barriers in public transport worldwide, research shows that public transport is still often perceived as challenging, inconvenient, and inaccessible for many people with disabilities. A growing body of research points to several issues, relating to the spatial and temporal distribution of public transport, affordability, safety, and social barriers
