Seeded free electron lasers theoretically have the intensity, tunability, and resolution required for multiphoton spectroscopy of atomic and molecular species. Using the seeded free electron laser FERMI and a novel detection scheme, we have revealed the two-photon excitation spectra of dipole-forbidden doubly excited states in helium. The spectral profiles of the lowest (-1,0)^{+1} ^{1}S^{e} and (
In this study, a multiphysics model is presented that predicts creep in three months old concrete cylinders subjected to drying. The model includes concrete hydration, and a moisture transport model with relative humidity as the driving potential. These parameters are important to include in order to simulate creep. The model was implemented in the finite element software COMSOL Multiphysics. The
We consider Hilbert spaces of analytic functions in the disk with a normalized reproducing kernel and such that the backward shift f(z)↦[Formula presented] is a contraction on the space. We present a model for this operator and use it to prove the surprising result that functions which extend continuously to the closure of the disk are dense in the space. This has several applications, for example

February 24, 2022, has become a turning point for the security situation in Northern Europe. Up until Russia’s attack on Ukraine, cooperation around the greater Baltic Sea Region had been highly successful in a variety of areas such as environmental protection, transportation networks, municipal networks, and innovative economies. All this was dealt a serious blow when Russian forces launched a fu

Acute myocardial infarction (AMI) is a disease associated with high morbidity and mortality. Currently there are no available treatments specifically targeting the post-ischemic myocardial processes that lead to heart failure and recurrent coronary events. The innate immune system plays a central role in the two consecutive phases that follow an acute ischemic event: the inflammatory phase and the
The sky view factor (SVF) is an important radiometric parameter for assessing the canopy energy budget of urban areas. There are several methods to determine the SVF observationally. The most common is taking a photo with a digital camera equipped with a fish-eye lens and then converting ratio of sky area to canopy area into SVF. However, most urban canopy models use this variable as derived from
Cabbage Dressing in Corona Times is a research project conducted by Charlotte and Sally that explores collaborative making, wearing, and undressing within the limitations of the global COVID-19 pandemic. The material of cabbage is chosen because of its impermanence — it easily decomposes, becoming symbolic of the fragility of our current context. The costumes have been created together but also se
Abstract The aim of this paper was to analyze slotted bone points from Scania, southern Sweden and to examine different aspects of them such as social areas of use, typology and chronology, what kind of animal that was hunted and how, what a manufacturing site might look like and what should be observed on the site and decoration. The slotted bone points occur in the early and the middle Mesolithi
