Deposition and 14C-based source apportionment of black carbon in a small lake in southern Sweden since 1450 CE

Black carbon (BC) is produced by incomplete combustion of biomass and fossil fuels and is released as aerosols to the atmosphere with effects on the climate, environment, and human health. Current BC emissions are well monitored in many parts of the world. However, the geographical coverage is limited, and historical records of BC accumulation are still scarce. Here we present a quantification of

Association of height, BMI, and smoking status with prostate cancer risk before and after the introduction of PSA testing in Sweden

Prostate cancer (PCa) incidence has steadily increased in Sweden, more steeply in the mid-1990s caused by increased opportunistic prostate-specific antigen (PSA) testing. Tallness, normal weight, and non-smoking are associated with more PSA testing, which increases detection of low-risk and localised PCa. We investigated time trends of height, body mass index (BMI), and smoking with PCa risk in 17

Topological Weyl altermagnetism in CrSb

Altermagnets constitute a novel, third fundamental class of collinear magnetic ordered materials, alongside with ferro- and antiferromagnets. They share with conventional antiferromagnets the feature of a vanishing net magnetization. At the same time they show a spin-splitting of electronic bands, just as in ferromagnets, caused by the atomic exchange interaction. On the other hand, topology has r

Physical activity and sedentary behaviour amongst children with obesity - exploring cross-sectional associations between child and parent

Background: Physical activity (PA) in childhood is critical for establishing a healthy lifestyle across the lifespan, particularly to treat and prevent obesity. This study aimed to explore PA and sedentary behaviour (SED) in 6–12-year-old children with obesity and their parents, and possible associations in these behaviours between children and parents. Methods: Children referred to outpatient pae

Plasma and MRI biomarkers capture neuronal damage in former professional boxers

Repetitive Head Impacts (RHI) in boxing may increase the risk for neuronal damage. We evaluated blood-based biomarkers for neurodegeneration and Alzheimer’s Disease (AD) pathology, clinical features, and MRI biomarkers in former professional boxers compared to patients with AD or patients with subjective cognitive decline (SCD). Nine former boxers were compared to age-matched patients (without sin

Genetic and environmental contributions to the link between synaesthesia and neurodevelopmental and psychiatric features : a twin study

Synaesthesia is a sensory phenomenon where specific inputs such as written letters or tastes automatically trigger additional sensations (for instance colours). The phenomenon is more common in people on the autism spectrum compared to the general population and seems also to be associated with other neurodevelopmental and psychiatric conditions and features. We assessed the associations between s

The status quo of fire evacuation drills in nursery schools

Fire drills are a commonly-used training method for improving how people act in emergency situations. This article deals with fire drills in early childhood education facilities and analyses data gathered from an online survey of 1 151 Czech nursery schools (23.5% of nursery schools invited to participate, 21.5% of all officially registered nursery schools in Czechia). It provides recommendations

Exploitable mechanisms of antibody and CAR mediated macrophage cytotoxicity

Macrophages infiltrate solid tumors and either support survival or induce cancer cell death through phagocytosis or cytotoxicity. To uncover regulators of macrophage cytotoxicity towards cancer cells, we perform two co-culture CRISPR screens using CAR-macrophages targeting different tumor associated antigens. Both identify ATG9A as an important regulator of this cytotoxic activity. In vitro and in

Fractional-statistics-induced entanglement from Andreev-like tunneling

The role of anyonic statistics stands as a cornerstone in the landscape of topological quantum techniques. While recent years have brought forth encouraging and persuasive strides in detecting anyons, a significant facet remains unexplored, especially in view of connecting anyonic physics to quantum information platforms—whether and how entanglement can be generated by anyonic braiding. Here, we d

Corneal epithelial aberrations : a novel diagnostic tool for keratoconus and forme fruste keratoconus

Purpose: To assess the ability of corneal epithelial aberrations to discriminate forme fruste keratoconus (FFKC) and keratoconus (KC) from normal eyes. Methods: This prospective, case-control study enrolled 91 right eyes from 91 normal participants, 87 eyes with FFKC and 148 eyes with KC. Epithelial aberrations for the 6-mm pupil were measured using an anterior segment optical coherence tomography

Do not steel our identities! The role of identity in shaping workers’ perceptions of “green” steel transitions

There has been a growing interest in how workers in high-carbon industries are impacted by low-carbon transitions and how such transitions can be implemented in a way that is just. This study explores the socio-cultural dimensions of these processes, focusing on the role of identity in shaping workers’ perceptions of low-carbon transitions and their ability to navigate change. It does so through a

Localization of Humanitarian Logistics : Moving from Strategic Intent to Implementation

The international humanitarian system has, since the 19th century, been activated during large-scale disasters when the capacities of the affected countries are overwhelmed. It comprises international humanitarian organizations (IHOs) and is funded by a variety of donors. Recently, this system has faced increasing criticism, mainly because of its failure to empower and include local and national a

Flight energetics in migratory birds: integrating wind-tunnel measurements and migration ecology

Birds migrate across the globe on their wings, a behavioural adaptation that allows birds to exploit seasonal environments. Their migrations are ultimately influenced by their ability to fly, a costly but high energy-efficient mode of locomotion that enables birds to travel far distances in a short amount of time. This thesis investigates bird migration from a flight energetic perspective, focusin

Acoustic streaming on antibody-functionalized screen-printed electrode enhances detection sensitivity and total assay duration for voltammetric immunosensing of newcastle disease virus

Conventional diagnostic methods often involve long incubation times due to limited fluid mixing in confined spaces, despite offering high sensitivity. Therefore, acoustic streaming was employed to enhance microscale advection, thereby improving biomolecular interactions and reducing assay duration. The micromixing capability was demonstrated by dispersing methylene blue (MB) in deionized water and
