Integrating molecular photoswitch memory with nanoscale optoelectronics for neuromorphic computing
Photonic solutions are potentially highly competitive for energy-efficient neuromorphic computing. However, a combination of specialized nanostructures is needed to implement all neuro-biological functionality. Here, we show that donor-acceptor Stenhouse adduct dyes integrated with III-V semiconductor nano-optoelectronics have combined excellent functionality for bio-inspired neural networks. The

Problems, problem-solving and problem-solving networks - a theoretical foundation for FIRE21 : Version 2
This document is created within the research project Nordic Fire and Rescue Services in the Twenty First Century (FIRE21). In this project, the fire and rescue services are seen as both governed by, and dependent on, formal and informal networks. A fundamental assumption in the research project is that efficient emergency management is dependent on efficient problem-solving in these networks. As a
Methods to Investigate the Quality of Stabilized Dredged sediments
Dredging operations in ports, rivers, and waterways are essential for maintaining navigable depths, but they result in large volumes of dredged sediments (DS) that are often unsuitable for immediate reuse due to their high moisture content, low strength, and contamination. Stabilization and solidification (S/S) techniques are widely employed to improve the geotechnical properties of DS, making theDredging operations in ports, rivers, and waterways are essential for maintaining navigable depths, but they result in large volumes of dredged sediments (DS) that are often unsuitable for immediate reuse due to their high moisture content, low strength, and contamination.

Satir handlar sällan om att enbart roa
"Man kan fråga sig varför de som otvivelaktigt har makt att påverka samhället lockas så pass av satiren. De har ju redan makten att påverka på andra sätt.” Det skriver medieforskaren Joanna Doona, författare till Det politiska skrattet: satir och medborgarskap, apropå debatten kring sverigedemokraten Richard Jomshofs spridande av muslimfientliga bilder.
C4b-Binding Protein and Factor H Attenuate NLRP3 Inflammasome-Mediated Signalling Response during Group A Streptococci Infection in Human Cells
Introduction: Streptococcus pyogenes (group A streptococcus; GAS) is a pathogen causing over half a million deaths annually worldwide. Human immune cells respond to GAS infection by activating the NLRP3 inflammasome leading to the release of pro-inflammatory cytokines that control infection. We investigated the role of C4b-binding protein (C4BP) and factor H (FH) in the inflammasome response to GA
Few-Body Quantum Rings : An Exact Diagonalization Approach
This thesis investigates few-body quantum rings, particularly in the study of ultracold bosonic gases and nanowire quantum dots. These systems are investigated numerically using exact diagonalization methods. This dissertation contains five chapters which develop numerical and theoretical background for understanding the few-body calculations and analysis contained in the four included papers: Pap
In Situ Studies of Atomic Layer Deposition of Hafnium Oxide on (Ag,Cu)(In,Ga)Se2 for Thin Film Solar Cells
Ambient pressure X-ray photoelectron spectroscopy is employed to study in real time the chemical reactions occurring on (Ag,Cu)(In,Ga)Se2 (ACIGSe) surfaces during the first atomic layer deposition (ALD) cycle of HfOx under realistic synthesis conditions by using tetrakisdimethylamido-hafnium (TDMA-Hf) and H2O precursors. We find that the initial deposition due to surface reactions of HfOx ALD on A
The illusion of attendance : a critical study of large-class lectures
Large-class university lectures remain commonplace, yet their educational value is contested. While the majority of criticism contrasts transmissive lectures with active learning pedagogies, this case study evaluates a lecture series on its intrinsic qualities, looking at staff and student understandings of the lecture’s contribution to academic outcomes and the affect attendance has on students’
The Wayqecha Amazon Cloud Curtain Ecosystem Experiment : A new experimental method to manipulate fog water inputs in terrestrial systems
Fog makes a significant contribution to the hydrology of a wide range of important terrestrial ecosystems. The amount and frequency of fog immersion are affected by rapid ongoing anthropogenic changes but the impacts of these changes remain relatively poorly understood compared with changes in rainfall. Here, we present the design and performance of a novel experiment to actively manipulate low ly
Propagation of Orientation Across Lengthscales in Sheared Self-Assembling Hierarchical Suspensions via Rheo-PLI-SAXS
Simultaneous rheological, polarized light imaging, and small-angle X-ray scattering experiments (Rheo-PLI-SAXS) are developed, thereby providing unprecedented level of insight into the multiscale orientation of hierarchical systems in simple shear. Notably, it is observed that mesoscale alignment in the flow direction does not develop simultaneously across nano-micro lengthscales in sheared suspen
Platelet characteristics in extremely preterm infants after fatty acid supplementation : a randomized controlled trial
Background: Two risk factors for severe retinopathy of prematurity (ROP) in extremely preterm infants are thrombocytopenia and low levels of arachidonic acid (AA) and docosahexaenoic acid (DHA). To date, these risk factors have not been linked. Method: Infants born < 28 weeks gestational age (GA) from 2016 to 2019 were randomized to postnatal enteral AA/DHA supplementation or standard care (contro
Prenatal exposure to endocrine disrupting chemicals and the association with behavioural difficulties in 7-year-old children in the SELMA study
Background: Endocrine disrupting chemicals (EDCs) can cross the placenta and thereby expose the fetus, which may lead to developmental consequences. It is still unclear which chemicals are of concern regarding neurodevelopment and specifically behaviour, when being exposed to a mixture. Objective: The objective is to determine associations between prenatal exposure to EDCs and behavioural difficul
En ökad press att hantera utländsk påverkan i den akademiska sektorn: Bakgrund och utmaningar
Det globala akademiska landskapet har förändrats avsevärt sedan 1990-talet. Idag deltar fler länder än någonsin i produktionen av forskning av hög kvalitet, och internationella samarbeten inom högre utbildning har ökat markant under de senaste tre årtiondena på grund av globalisering och ökad personmobilitet. Det är tydligt att internationella utbyten och ökad personmobilitet har stärkt Sveriges f

Chromosome-scale genome assembly reveals how repeat elements shape non-coding RNA landscapes active during newt limb regeneration
Newts have large genomes harboring many repeat elements. How these elements shape the genome and relate to newts' unique regeneration ability remains unknown. We present here the chromosome-scale assembly of the 20.3 Gb genome of the Iberian ribbed newt, Pleurodeles waltl, with a hitherto unprecedented contiguity and completeness among giant genomes. Utilizing this assembly, we demonstrate conserv
Epithelial ovarian cancer is infiltrated by activated effector T cells co-expressing CD39, PD-1, TIM-3, CD137 and interacting with cancer cells and myeloid cells
INTRODUCTION: Despite predicted efficacy, immunotherapy in epithelial ovarian cancer (EOC) has limited clinical benefit and the prognosis of patients remains poor. There is thus a strong need for better identifying local immune dynamics and immune-suppressive pathways limiting T-cell mediated anti-tumor immunity.METHODS: In this observational study we analyzed by immunohistochemistry, gene express
How low can you go? : Antibiotic use in Swedish dogs with gastroenteritis
BACKGROUND: Canine gastroenteritis (CGE) is a common cause for seeking veterinary care in companion animal medicine and an area where antibiotics have been reported to be widely used. Therefore, creating relevant benchmarks for antibiotic use in CGE is important when implementing and analyzing antibiotic stewardship interventions. The aim of this paper was to describe the level and temporal trend
