Increased antibiotic efficacy and noninvasive monitoring of Staphylococcus epidermidis biofilms using per-cysteamine-substituted γ-cyclodextrin - A delivery effect validated by fluorescence microscopy

Limited and poor delivery of antibiotics is cited as one reason for the difficulty in treating antibiotic-resistant biofilms associated with chronic infections. We investigate the effectiveness of a positively charged, single isomer cyclodextrin derivative, octakis[6-(2-aminoethylthio)-6-deoxy]-γ-CD (γCys) to improve the delivery of antibiotics to biofilms. Using multiphoton laser scanning microsc

Det er tydeligt, at globale diskurser om sund og succesfuld aldring (se bl.a. Lamb 2014 og 2017) har fundet vej ind i den lokale drejebog for, hvad der udgør det optimale livsforløb (Oxlund 2018). Med fokus på fysisk aktivitet og individuel optimering har ideerne om sund aldring været med til at løfte barren for, hvad den enkelte forventes at investere i for både at føje år til livet og liv til år

The social Waste Issue, symptoms of awareness and responsibility: A Thematical Analysis of Social Relations to Waste Management in Sweden

The growing accumulation and mismanagement of waste disrupt the ecological systems that sustain human existence, leaving environmental burdens for future generations. This situation highlights the need for circular approaches such as zero-waste management, where waste is treated as a resource rather than discarded. Studying social waste relations in Sweden is particularly relevant, given the count

A histidine pseudokinase modulates polar growth and cell shape in Streptomyces venezuelae

Polar growth and cell shape determination in mycelium-forming Streptomyces bacteria depends on the function of a polarly localised multiprotein complex that directs cell wall synthesis – the polarisome. This complex assembles around the essential cell polarity determinant DivIVA, alongside other largely unknown components. We report here the discovery of a conserved hybrid histidine kinase-like pr

Memory retention of spatial knowledge in fire evacuation and safety training

This study investigated the retention of spatial knowledge in buildings following route-learning training in a virtual reality environment. A total of 121 participants were tested up to three months later on putting waypoints of the route in the correct order and recalling directions at waypoints. Memory accuracy declined over time, consistent with classic memory theory. Route knowledge was retain

Age of information in relativistic communication systems

Age of Information (AoI) is a widely used metric to quantify the freshness of updates in communication systems. Existing AoI analyses implicitly assume a shared or synchronized notion of time between transmitter and receiver, thereby neglecting distortions arising from relative motion and gravitational effects. In this paper, we investigate the impact of relativistic time dilation on information f

Annotation and characterization of lesions in breast tomosynthesis images

Rapid adoption of artificial intelligence methods in breast imaging research emphasizes the need for large, appropriately curated image databases for development and validation. For digital breast tomosynthesis (DBT), there are few public databases with only limited lesion annotation. Recently, we have developed Malmö Breast ImaginG (M-BIG), a large database of 104 791 women screened at Skåne Univ

Independent directors’ reputation incentives and executive pay tournaments

We provide evidence of a positive association between independent directors’ reputation incentives and the magnitude of the CEO pay gap, defined as the difference in compensation between the CEO and lower-ranked executives. The CEO pay gap serves as a proxy for the strength of executive pay tournaments within the firm. Using a sample of S&P 1500 firms, we show that independent directors with s

Fireburn : Revolt, Representation, and Remembrance

This dissertation examines the Fireburn revolt of 1878 on St. Croix in the Danish West Indies as both a historical event and a site of ongoing meaning-making. Rather than approaching Fireburn solely as a moment of post-emancipation labor unrest, the study investigates how the revolt has been archived, mediated, represented, and remembered across time and space, from the late nineteenth century to

Mapping textures of polar ice cores using 3D laboratory X-ray microscopy

Deep ice cores from polar ice sheets enable reconstructions of Earth’s past climate. Ice core records are therefore crucial for projecting future climate change, but our ability to interpret them relies on our understanding of polycrystalline-ice microstructures and mechanics. In turn, these microstructures enable modeling of ice flow and large-scale effects of ice sheet evolution. Since drilling

Implementering av blå-grön infrastruktur i Sverige : Barriärer för storskalig implementering av blå-grön infrastruktur och några förslag till hur dessa kan överbryggas

Traditionella, rörbaserade dagvattensystem räcker inte längre till i förtätade städer för att möta krav på vattenkvalitet och översvämningsskydd vid extrem nederbörd. Därför efterfrågas naturbaserade och multifunktionella lösningar, här omnämnda som blå-grön infrastruktur, som kan hantera flera samhällsutmaningar samtidigt.Implementeringen av sådana lösningar försvåras dock av många och ibland sam

Enhanced remote sensing of water surface elevation through fusion of Sentinel-3 altimeter data and climate variables using machine learning

Accurate and continuous monitoring of inland surface‌ water dynamics is vital for sustainable water resource management, climate impact assessment, and ecological planning. This study introduces a machine learning-based remote sensing-based data-fusion framework that improves Sentinel-3 radar altimeter (SRAL) estimations of water surface elevation (WSE) by integrating ERA5 reanalysis climate varia

Nytilkomne familier bliver mødt med mange krav fra den danske velfærdsstat. Et af kravene er, at de skal sende deres 0-6 årige børn i dagtilbud, så forældrene kan gå på sprogskole eller komme i praktik. Artiklen belyser nogle af de dilemmaer, der opstår i forældresamarbejdet i mødet mellem pædagoger og nytilkomne familier. Disse dilemmaer udspringer af den myndighedsrolle som pædagogerne har, samt
