Aim: To validate a deep-learning (DL) algorithm for automated quantification of prostate cancer on positron emission tomography/computed tomography (PET/CT) and explore the potential of PET/CT measurements as prognostic biomarkers. Material and methods: Training of the DL-algorithm regarding prostate volume was performed on manually segmented CT images in 100 patients. Validation of the DL-algorit

This paper adds to the small literature on the role of welfare benefits and mental health by studying the relationship between uptake of Social Assistance Benefit (SAB) and objective mental health measures. We use rich longitudinal administrative data on income, unemployment benefits and psychopharmaceutic prescriptions (antidepressants, anxiolytics, and hypnotics) for more than 140,000 Swedes in

The paper/presentation gives an overview of Peer-Assisted Study Schemes (SI-PASS) in Higher Education in Europe. SI-PASS is a method of improving student performance in “difficult” courses combining “how to learn” with “what to learn”. SI-PASS sessions are scheduled parallel to the regular education and are guided and facilitated by a “senior” student, the SI-PASS leader. The sessions are based on

The main goals of SI are usually to improve learning and student performance as well as increasing retention. The achievement of these goals are evaluated based on linking SI attendance with retention and student results (student performance is here often seen as a proxy for learning). However, the objectives with introducing an SI-program at a higher education institute is often so much more than

Inputs of crop residues and labile C (e.g. root exudates) can affect the decomposition rate of soil organic matter (SOM) through the priming effect (PE). Most previous priming studies describe the addition of single labile or residue C, ignoring the interactions of labile C and fresh or decaying crop residues commonly present in field conditions. Using a dual 13C/14C labelling approach in a 62-day

Crop residue quality and quantity have contrasting effects on soil organic matter (SOM) decomposition, but the mechanisms explaining such priming effect (PE) are still elusive. To reveal the role of residue quality and quantity in SOM priming, we applied two rates (5.4–10.8 g kg−1) of 13C-labeled wheat residues (separately: leaves, stems, roots) to soil and incubated for 120 days. To distinguish P

Acute hypotensive episodes are common during dialysis sessions, and represent a serious problem. Spectral analysis of heart rate variability (HRV) and barorrefle x sensitivity (BRS) is performed to study the behaviour of the autonomic nervous system (ANS) during the hemodialysis. The ratio between the low frequency (LF) and high frequency (HF) power of HRV, as well as BRS in the HF band, are signi

Allmänmedicin är ett brett område som spänner över många sjukdomstillstånd, med fokus på patientcentrering. Inom många områden sker en snabb kunskapsutveckling och rekommendationer för utrednings- och behandlingsstrategier uppdateras hela tiden. För en allmänläkare kan det vara svårt att hålla sig uppdaterad och tidsbrist begränsar möjligheterna att leta kunskap i det dagliga kliniska arbetet. Dig

Most studies on eco-evolutionary feedbacks concern the influence of abiotic factors, or predator–prey and host–parasite interactions, while studies involving sexual interactions are lagging behind. This is at odds with the potential of these interactions to engage in such processes. Indeed, there is now ample evidence that sexual selection is affected by ecological change and that sexually selecte

Field data on temperature and salt content structure in the vicinity of the bottom boundary in an ice‐covered lake are analyzed. A bottom boundary layer is identified, characterized by rapid increases in both temperature and salt concentration and having a thickness of ∼1 dm with respect to temperature and 2–4 cm with respect to salt content. A simple analytical model of the temperature distributi

Regional Studies is inextricably intertwined with history. Cultural and institutional legacies inform choices between different policy options, meaning that the past plays a crucial role in how we think about regional economic development, planning and policy.Through a selection of accessible theoretical, methodological and empirical chapters, this book explores the connections between regional de

Climbing racks, carousels, swings and slides can be used for many experiments and demonstrations that offer suprising results, often challenging students' understanding of motion. This paper describes activities used in professional development workshops for teachers on the use of playgrounds in physics teaching. Toys and other simple equipment complement the experience of the body. In addition, s

A method for respiratory rate estimation from electrocardiogram (ECG), based on variations in QRS complexes slopes, is evaluated over stress testing recordings. Besides the 12 standard, and the 3 vectorcardiogram (VCG), 2 additional leads derived from the VCG are analyzed. A total of 34 slope series were studied, 2 for each lead: slopes between the peaks of the Q and R waves, and between the peaks
