We introduce the notion of a-walk S(n) = a1X1 +… + anXn, based on a sequence of positive numbers a = (a1, a2,…) and a Rademacher sequence X1,X2,…. We study recurrence/ transience (properly defined) of such walks for various sequences of a.
A higher intake of gluten during childhood is associated with increased risk of celiac disease, and the incidence of celiac disease peaks shortly after the time point when associations with higher gluten intake during the second and third year of life occur. Additional environmental factors are most likely necessary for celiac disease to develop. It is hypothesized that gastrointestinal infections
Stone heart (ischemic contracture) is a rare and serious condition observed in the heart after periods of warm ischemia. The underlying mechanisms are largely unknown and treatment options are lacking. In view of the possibilities for cardiac donation after circulatory death (DCD), introducing risks for ischemic damage, we have investigated stone heart in pigs. Following cessation of ventilation,
Aim: Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reliability of those predictions, they need to be critically validated with respect to what they are used for. While ecologists are typically interested in how and where distributions will change, we argue that SDMs have seldom been eva
Heterotopic mineralization entails pathological mineral formation inside soft tissues. In human tendons mineralization is often associated with tendinopathies, tendon weakness and pain. In Achilles tendons, mineralization is considered to occur through heterotopic ossification (HO) primarily in response to tendon pathologies. However, refined details regarding HO deposition and microstructure are
Background: Moderate-to-severe hemophilia B is treated with lifelong, continuous coagulation factor IX replacement to prevent bleeding. Gene therapy for hemophilia B aims to establish sustained factor IX activity, thereby protecting against bleeding without burdensome factor IX replacement. Methods: In this open-label, phase 3 study, after a lead-in period (≥6 months) of factor IX prophylaxis, we
The ecological effects of mass-flowering crops on pollinator abundance and species richness of neighbouring habitats are well established, yet the potential evolutionary consequences remain unclear. We studied effects of proximity to a mass-flowering crop on the pollination of local co-flowering plants and on patterns of natural selection on a pollination-generalised plant on the Tibetan Plateau.
Background: Community-based day centres (DC) in Sweden provide support to people with severe mental health problems. The role of DC motivation for outcomes in terms of occupational engagement and personal recovery is yet unknown. Aims: To compare two groups who received DC services, one of which also received the 16-week Balancing Everyday Life (BEL) intervention. The focus was motivation for DC s
The aim was to explore existential loneliness in different long-term care contexts as narrated by older people. A qualitative secondary analysis was performed of 22 interviews with older people in residential care, home care, and specialized palliative care. The analysis started with naive reading of interviews from each care context. As these readings showed similarity with Eriksson’s theory of t
Objectives: In Sweden, pneumococcal serotype distribution in adults with community-acquired pneumonia (CAP) and potential coverage of currently licensed pneumococcal conjugate vaccines (PCVs) is unknown. Methods: During 2016–2018, patients aged ≥18 years hospitalized with radiologically confirmed (RAD+) CAP were enrolled at Skåne University Hospital in a study on the etiology of CAP in Sweden (ECA
Dynamic glucose enhanced (DGE) chemical exchange saturation transfer (CEST) MRI is an emerging imaging technique that provides a molecular-specific type of image contrast, based on magnetic labelling of exchangeable protons. The technique enables the use of biodegradable sugars as contrast agents, and such compounds are believed to have less side effects than conventional MRI contrast agents.

Following his acclaimed earlier study on mediumship and survival, Alan Gauld providesa more complete account of about 50 years of early studies on mediumship with a select group ofmediums (e.g., Mrs. Piper, Mrs. Leonard, Mrs. Dowden). He describes in detail why many if not mostof the criticisms against extraordinarily accurate accounts by these mediums do not hold waterwhen analyzed in detail. Gau
There is limited theoretically informed research on sustainability in the space tourism market. An extended model of goal-directed behaviour (EMGB) is created and verified with individual and organizational interventions, comparing space tourism experienced and non-experienced travellers. Results revealed that individual intervention has fully significant effects on all MGB constructs, while organ
