Background: The aim was to investigate to what extent the quantification of myocardial blood flow (MBF) from dynamic 13N-NH3 positron emission tomography (PET) images is affected by time frame schemes, time-of-flight (ToF), reconstruction algorithms, blood pool volume of interest (VOI) locations and compartment models in patients with suspected chronic coronary syndrome. Methods: A standard MBF va
Robots and autonomous systems are being developed at an ever-increasing rate. Autonomous systems are already prolific in many households around the world, and their adoption is only expected to increase over the coming decades. Even so, many of the systems that are deployed today are still prone to small operational errors such as struggling to navigate complex environments. While the argument ove
The generalized asymmetric Laplace (GAL) distributions, also known as the variance/mean-gamma models, constitute a popular flexible class of distributions that can account for peakedness, skewness, and heavier-than-normal tails, often observed in financial or other empirical data. We consider extensions of the GAL distribution to the matrix variate case, which arise as covariance mixtures of matri
This chapter is an attempt to provide an interdisciplinary approach and appraisal. Methodologically, the chapter combines law with several disciplines in cultural studies, namely, history, ethics, and philosophy. The overarching objective is to provide a succinct overview of the development of China's Belt and Road Initiative (BRI) while, at the same time, homing in on some of the main themes and
Background: Dietary carbohydrates are a major source of energy in the Nordic and Baltic countries. The health effects of different types of carbohydrates vary and there is a need to update the evidence regarding specific carbohydrates and their effects on health-related outcomes. Objective: The aim of this scoping review was to describe the evidence for the role of total carbohydrates (fiber exclu
The purpose of this study was to describe experiences of pain among students at upper secondary schools (adolescents aged 16–19 years) in Sweden. Focus group (n = 9) interviews with 41 adolescents were conducted in southern Sweden in 2021. The interviews were analyzed by qualitative content analysis, which identified four categories encompassing the theme how pain expressed itself: (1) a warning b
This editorial introduces the issue of Journal of Scandinavian Cinema (JSCA), which focuses on representations of various social identities in diverse historical and cultural contexts. The issue includes articles on race and post-colonialism, gender and sexuality, and class and nation in Nordic films. The editorial summarizes main arguments and contributions of each article and highlights the rele
Background: Insulin resistance is a hypothesised biological mechanism linking obesity with prostate cancer (PCa) death. Data in support of this hypothesis is limited. Methods: We included 259,884 men from eight European cohorts, with 11,760 incident PCa’s and 1784 PCa deaths during follow-up. We used the triglyceride-glucose (TyG) index as indicator of insulin resistance. We analysed PCa cases wit
Streak cameras are central to measurements across the sciences. By spatially modulating the entrance slit, we show a more than 20% increase in temporal resolution opening up for sub-picosecond measurements with standard streak camera systems.
In the last 30 years, molecular imprinting has been evidenced as a desirable approach to design artificial, specific, and selective recognition sites for the target molecules/cells. Molecularly imprinted polymers (MIPs) are the most encouraging reflection of the advanced area of biomimetics and have attracted important popularity for the detection of many types of molecules including peptides, pro
Data regarding excretion of SARS-CoV-2 in semen are inconclusive and counseling regarding risk of sexual transmission is still challenging. Our knowledge on the effect of upper respiratory tract infections (URTI) on male reproductive system is also scarce. Apart from negative effect of fever on spermatogenesis virtually no study has been able to compare reproductive parameters in men with COVID-19
This paper concerns the inverse problem of determining a planar conductivity inclusion. Our aim is to analytically recover from the generalized polarization tensors (GPTs), which can be obtained from exterior measurements, a homogeneous inclusion with arbitrary constant conductivity. The primary outcome of recovering a homogeneous inclusion is an inversion formula in terms of the GPTs for conforma
The dissociative double photoionization of isoxazole molecules has been investigated experimentally and theoretically. The experiment has been carried out in the 27.5-36 eV photon energy range using vacuum ultraviolet (VUV) synchrotron radiation excitation combined with ion time-of-flight (TOF) spectrometry and photoelectron-photoion-photoion coincidence (PEPIPICO) technique. Five well-resolved tw
Renewable energy (RE) integrated with a hybrid electric-hydrogen storage system (HEHSS) is considered a promising solution for data centers to increase their energy efficiency and decrease their greenhouse emissions. This paper proposes a forecasting based hierarchical energy management strategy for a data center with wind energy, tidal energy and HEHSS, which is taken as a microgrid. A multi-popu
Introduction: Patients requiring postcardiotomy veno-arterial extracorporeal membrane oxygenation (V-A-ECMO) have a high risk of early mortality. In this analysis, we evaluated whether any interinstitutional difference exists in the results of postcardiotomy V-A-ECMO. Methods: Studies on postcardiotomy V-A-ECMO were identified through a systematic review for individual patient data (IPD) meta-anal
Background and purpose: Impulse control disorders (ICDs) are common among Parkinson's disease patients using dopamine agonists. We wanted to determine whether ICD patients have higher dopamine agonist serum concentrations than those without any sign of ICD. Methods: Patients who used either pramipexole or ropinirole depot once daily were screened for ICDs using the validated Questionnaire for Impu
