This paper contains the analysis of the transmission problem with a spherical,dielectric (possibly lossy) shell. The sources to the problem are located insidethe spherical, dielectric shell. Two different source configurations are investigated- an off-center located electric dipole and a circular Huygens surface.An exact modal series solution of the transmission problem is found and thesolution is
A limitation of current LoRa networks is their single-hop nature. This causes difficulties in areas with poor Internet access, such as remote rural areas, or challenging radio environments, for example in metropolitan areas, as the LoRa gateway must be placed at a location with backhaul access to the network server, but must nonetheless be reachable by all end devices. To facilitate these applicat
BACKGROUND AND AIM: Persistent organochlorine pollutants (POPs) have in epidemiological studies been associated with health hazards. The exposure window might be crucial and it is, accordingly, important to analyze exposure concentrations in samples collected at the window of interest. This makes the use of stored blood samples extremely interesting. However, small blood volumes from stored sampl
The planetary changes associated with the Anthropocene, including climate change and extinction of species, pose severe threats to civilization, humanity, and the natural world as we know it. They also pose special challenges to the human imagination. To meet these challenges, climate change communicators use narratives. Nonfiction books intended for a general audience employ two radically differe

Activation of the kynurenine pathway (KP) with resulting accumulation of neuroactive metabolites may be a downstream pathophysiological mechanism of inflammatory depression. The aims of this study were to investigate KP metabolites in inflammatory depression compared to non-inflammatory depression and healthy controls, and whether these metabolites change with nutraceutical interventions with pote
Mobile communications are now evolving towards the fifth generation (5G). In the near future, we expect an explosive increase in the number of connected devices, such as phones, tablets, sensors, connected vehicles and so on. Much higher data rates than in today's 4G systems are required. In the 5G visions, better coverage in remote regions is also included, aiming for bringing the current "4 bill
From June to November 1945, over 70 shipments of flat-packed architectural elements arrived at the harbours of Nexø and Rønne on the Danish island Bornholm. The shipments consisted of prefabricated interior fixtures and ready-to-be mounted walls. The Danish municipality prepared infrastructure, named new roads, and within a year, 300 wooden houses were assembled on site.

Wild bee populations are threatened by current agricultural practices in many parts of the world, which may put pollination services and crop yields at risk. Loss of pollination services can potentially be predicted by models that link bee abundances with landscape-scale land-use, but there is little knowledge on the degree to which these statistical models are transferable across time and space.
