BackgroundPresence of a prosthetic joint entails a life-long risk of haematogenous periprosthetic joint infection (hPJI) during bacteraemia. For bacteraemia with Staphylococcus aureus the hPJI frequency has been described to be up to 40% and for streptococci up to 20%, with large variation among reported frequencies.ObjectivesWe aimed to investigate the hPJI frequency from bacteraemia with virulen

We theoretically investigate a thermoelectric heat engine based on a single-level quantum dot, calculating average quantities such as current, heat current, output power, and efficiency, as well as fluctuations (noise). Our theory is based on a diagrammatic expansion of the memory kernel together with counting statistics, and we investigate the effects of strong interactions and next-to-leading or

MOTIVATION: Missing data present a pervasive challenge in data analysis, potentially biasing outcomes and undermining conclusions if not addressed properly. Missing data are commonly classified into Missing Completely at Random (MCAR), Missing at Random (MAR), and Missing Not at Random (MNAR). While MCAR poses a minimal risk of data distortion, both MAR and MNAR can seriously affect the results of

Känslan av mobilskärmen mot fingertoppen, klickljuden från kollegan som knappar på tangentbordet, skenet från en färgglad televisionsskärm som lyser upp vardagsrummets dunkel ... Den moderna människans tillvaro präglas av hens samspel med informationshanterande elektronik, och förbättringar inom informationsteknik är därmed av stor betydelse för en högre levnadsstandard. Ett sätt att förbättra kom[8]annulene units linked by alternating benzo[a,e]moieties are a promising new design for electro-responsive hydrocarbons. However, current methods for synthesizing benzo[8]annulenes limit the prospect of constructing longer multimers. In this work, an alternative synthesis route to the compound containing two [8]annulene moieties was pursued. The dimeric compound was ultimately furnished over thr

Nuclear fission leads to the splitting of a nucleus into two fragments1,2. Studying the distribution of the masses and charges of the fragments is essential for establishing the fission mechanisms and refining the theoretical models3,4. It has value for our understanding of r-process nucleosynthesis5,6, in which the fission of nuclei with extreme neutron-to-proton ratios is pivotal for determining

Vem är den unge kamraten? Vad finns kvar av det som en gång var en rörelse? Vad hände med alla storslagna drömmar om att förändra världen? Vad gör vi om vi redan förlorat och våra fiender sitter vid makten? Med föreställningarna Våld & pedagogik och Kropp & straff ville dramatikern Henrik Bromander och regissören John Hanse skapa nya lärostycken som tog sikte på samtidens akuta frågor. Ins

Contextual shifts are crucial for episodic memory, setting event boundaries during event segmentation. While lab research provides insights, it often lacks the complexity of real-world experiences. We addressed this gap by examining perceptual and conceptual boundaries using virtual reality (VR). Participants acted as salespeople, interacting with customers in a VR environment. Spatial boundaries

Memories link elements across event boundaries, integrating overlapping content experienced at different times and places. Such memory representations are thought to rely on memory integration mechanisms. The present study used multivariate pattern analysis (MVPA) of electroencephalographic (EEG) data to elucidate the temporal dynamics of integrative encoding memory processes. Memory integration w

Interview with Swedish jazz pianist Jan Lundgren on storytelling in jazz improvisation.

Swedish art and music schools (SAMS), established in the 1940s, aim to provide affordable extra-curricular instrumental and singing education for all children, regardless of their parents’ economic situation. The tuition is highly subsidized, with families contributing only about 7% of the tuition costs. While traditionally focusing on one-to-one instruction, a recent governmental report (2016) ha

Episodic memory allows the flexible retrieval of commonalities and idiosyncrasies of overlapping life events. For example, seeing a woman in the city with your colleague's daughter may form an integrated memory representation involving the woman and your colleague. However, you may also keep a specific representation of the city event to talk with your colleague about the circumstances of having m

Reading An Yu’s Poetry (Preface)

Postgraduate education has been recognised as a key to bring about societal change. While further capacity building is imperative in this regard in East Africa (Wao et al., 2022), we will in this study focus on how supervisors function as important role models to their students (Brodin et al., 2020). We assume that supervisors’ own approaches to societal change affect their supervisor relationship
