Psychiatric, physical and biological aspects of posttraumatic stress disorder (PTSD) may be associated with dysfunctions in several cellular processes including nitric oxide (NO) production. NO is synthesized from arginine in a reaction carried out by NO synthase (NOS) enzymes. The recently introduced "global arginine bioavailability ratio" (GABR; ratio of arginine to [ornithine+ citrulline]) has

Generative product design systems used in the context of mass customization are required to generate diverse solutions quickly and reliably without necessitating modification or tuning during use. When such systems are employed to allow for the mass customization of product form, they must be able to handle mass production and engineering constraints that can be time-consuming to evaluate and diff

Popular Abstract in Swedish De svenska framtidsuttrycken (futuralt presens, futuralt skola och futuralt komma) är alla kontextuellt betingade användningar av uttryck som också har andra funktioner. Syftet med min avhandling är att beskriva vilka kontextvillkor som måste vara uppfyllda för att de tre uttrycken ska fungera som framtidsuttryck. I den modell över svenskans temporala system som presentThe main aim of this study is to specify the contextual conditions that apply to the use of the three central expressions for the future in Swedish: the present form and the auxiliaries skola and komma. A tense suffix indicates a temporal domain and states that a mediating element, here called FIX, is placed in the indicated domain. The present suffix points to a domain that overlaps temporally wi

Surface temperature in internal combustion engines is of high interest when studying heat losses. Two approaches for retrieving the surface temperatures are thermocouples and Laser Induced Phosphorescence, LIP. This study aims to analyze LIP as a technique for measuring surface temperature in internal combustion engines. The motivation for this study is the need for accurate surface temperatures w

Three theoretical atomic structure projects of interest for the astrophysical community and the lightning industry which are partially finished will be presented. Extensive ab initio calculations of properties of astrophysical interest has been done or are under its way for Ga I, Ga II, Ga III, In II and In III. The aim of the project is to also make calculations for In I, Tl I, Tl II and Tl III.

Denna avhandling utvecklar och utvärderar språkbaserade bedömningar som använder artificiell intelligens (AI) för att omvandla öppet språk till kvantitativa indikatorer och beskrivningar av psykiska hälsorelaterade konstruktioner. Medan slutna skalor länge har dominerat psykologiska bedömningar, är de begränsade av fasta svarsformat och kanske inte helt fångar komplexiteten i individers upplevelseThis thesis develops and evaluates language-based assessments that use artificial intelligence (AI) to transform open-ended language into quantitative indicators and descriptions of mental health related constructs. While closed-ended scales have long dominated psychological assessment, they are limited by fixed response formats and may not fully capture the complexity of individuals’ experiences.

Background: Physiologically guided revascularization improves clinical outcomes. The cutoff values for deferral with fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are the same across all coronary arteries, despite differences in coronary flow patterns. The objective was to compare deferral rates using either FFR or iFR in the right coronary artery (RCA), left anterior desce

Background: Previous studies suggest an antidepressant effect of omega-3 fatty acids (n-3 PUFAs). This effect may be larger in patients with low-grade inflammation, defined as mild elevations of high sensitivity C-reactive protein or other commonly used inflammatory markers. The antidepressant mechanisms of n-3 PUFAs are not fully understood but may involve modulation of immunometabolic processes

We have used approximately 40 fs pulses from a Ti:sapphire laser to investigate the ultrafast energy transfer and relaxation dynamics in the light-harvesting pigment-proteins of photosynthetic purple bacteria. Our results reveal two new features, not earlier observed in light-harvesting pigments: (1) ultrafast relaxation characterized by a time constant of approximately 20 fs, which we interpret a

In the Swedish context, ‘intergenerational Collaborative Housing’ and ‘Collaborative Housing for the second half of life’ (CH2L), based on the self-work model, were developed in the 1980s and 1990s. The chapter examines how ageing individuals developed caring practices and mutual support strategies in these collective housing forms and how such practices were adapted during the COVID-19 pandemic.

This chapter provides an overview of the different optical sectioning methods that enable performing three dimensional (3D) imaging of possibly complex samples. It discusses their benefits and limitations regarding their penetration depth, their imaging speed, their photo-toxic effect or their complexity. Focusing on fluorescence imaging, the chapter dives into approaches that make it possible to

Introduction: Divers are reported to have a lower ventilatory response to elevated levels of carbon dioxide (CO₂) than non-divers. Hypoventilation with CO₂ retention during diving is potentially dangerous. It is unknown if CO₂ retention is largely inherited or develops during diving training. We aimed to investigate if a military dive training course would influence the ventilatory response to CO₂

Introduction: Using time-limited trials of low-dose, sustained-release morphine to reduce chronic breathlessness to evaluate net effects may generate opioid withdrawal symptoms if medication is ceased. This sub-study of a larger randomized, placebo-controlled, double-blind trial aimed to evaluate if this occurred. Methods: People with modified Medical Research Council breathlessness scores of 3 or

Growth and immune development—fundamental parts of any organism's ontogeny—depend critically on nutrient availability, particularly on essential amino acids that support protein synthesis and physiological processes. However, environmental variation can reduce prey diversity and nutrient quality, producing suboptimal diets that lack essential amino acids, potentially constraining development. In t

The main information in DNA is its four-letter sequence that builds up the genetic information and that is traditionally read using sequencing methodologies. DNA can, however, also carry other important information, such as epigenetic marks and DNA damage. This information has recently been visualized along single DNA molecules using fluorescent labels. Quantifying fluorescent labels along DNA is
