The Fourier slice theorem for the standard Radon transform generalizes to a Laplace counterpart when considering the exponential Radon transform. We show how to use this fact in combination with algorithms for the unequally spaced fast Laplace transform to construct fast and accurate methods for computing both the forward exponential Radon transform and the corresponding back-projection operator.
MAX IV-laboratoriet är en anläggning med syfte att producerasynkrotronljus till forskning. När laddade partiklar accelereras skickar de ut energi i form av strålning kallad synkrotronljus. Synkrotronljus är intensivt ljus med många olika våglängder och är därför väldigt användbart för att studera strukturer och processer inom många olika fält såsom materialforskning, medicin, geologi och arkeologiThe MAX IV facility includes two storage rings, operated at 1.5 and 3 GeV energy, for the purpose of producing high-brilliance synchrotron radiation for users. The 1.5 GeV ring replaces the previous MAX II and MAX III storage rings as a source of UV and soft X-rays, whereas the 3 GeV ring is optimized for hard X-rays. The 3 GeV ring is the first of a new generation of synchrotron light storagering
This article presents a comprehensive integration of current experimental evidence and theories about so-called parapsychological (psi) phenomena. Throughout history, people have reported events that seem to violate the common sense view of space and time. Some psychologists have been at the forefront of investigating these phenomena with sophisticated research protocols and theory, while others h
Article 83(2) TFEU, introduced by the Treaty of Lisbon, confers a power on the EU to harmonise Member States’ legislation to define criminal offences and criminal sanctions. Nonetheless, uncertainty persists as to whether this provision exhaustively determines the EU’s power to adopt criminal law to enforce its policies. The article outlines the core case for viewing art.83(2) TFEU as a lex specia
Over the last two decades the market for membrane technology in the food industry increased to a market volume of approx. € 50 million and is now the second largest industrial market for membranes after municipal water treatment in Germany. The key membrane technologies in the food industry are the pressure driven membrane processes; microfiltration, ultrafiltration, nanofiltration and reverse os
We present a new model for building up complete exclusive hadronic final states in high energy nucleus collisions. It is a direct extrapolation of high energy pp collisions (as described by Pythia), and thus bridges a large part of the existing gap between heavy ion and high energy physics phenomenology. The model is inspired by the old Fritiof model and the notion of wounded nucleons. Two essenti
Decision and Value of Information analyses can be highly computational demanding due to the exponential growth of the decision tree in dependency of the state and decision variables. Due to the advancement of computational methods in the last decades, decision problems with moderate complexity maybe solved by a software tool whereas highly complex analyses require tailored approaches, algorithms a
Public procurement accounts for a very large share of most economies worldwide. This conceptual article argues that the key to achieving more innovations when pursuing public procurement is to describe problems to be solved or functions to be fulfilled (functional procurement) instead of describing the products to be bought (product procurement). Contracting authorities need to identify the proble
While Bayesian Optimization (BO) is a very popular method for optimizing expensive black-box functions, it fails to leverage the experience of domain experts. This causes BO to waste function evaluations on bad design choices (e.g., machine learning hyperparameters) that the expert already knows to work poorly. To address this issue, we introduce Bayesian Optimization with a Prior for the Optimum
The learning curve during repetitive production and the associated forgetting during production breaks are fundamental issues in the understanding of behavior. A model is suggested that combines 3 basic findings, namely, that single memory traces decay according to a power function of the retention interval, that aggregated memory traces can be combined by integration, and that the time to produce
Oligonucleotides are short fragments of RNA or DNA that can act as active pharmaceutical ingredients (API) in medicines used to target a wide range of diseases, with further applications continuously emerging. Solid Phase Oligonucleotide Synthesis (SPOS) remains the dominant platform for oligonucleotide production. However, SPOS is characterized by high reagent consumption and a poor sustainabilit
Almost 10 years have passed since microtektites and microkrystites were reported for the Paleocene–Eocene (P–E) boundary in drill cores and outcrop in New Jersey and in ODP Hole 1051B in the western North Atlantic. The glassy spherules were interpreted to reflect an impact trigger for the Paleocene–Eocene Thermal Maximum (PETM). Since then, many detailed studies of sediment strata across the P–E b
This paper advances scholarship on deliberate destabilisation for sustainability transitions. To understand how deliberate destabilisation plays out in practice, the politics of such processes must be confronted. To this end, we bridge research on the political economy of sustainability transitions with recent theorisations of the deliberate destabilisation of unsustainable socio-technical regimes
Following legislation in 2010, all Swedish teachers, at all levels, had a double mission: to teach democracy as well the content of their subject. This mission was seen as troublesome by evaluating authorities, among others. In the latest state curriculum, rhetoric has re-emerged as a central element of Swedish mother-tongue high school education and is also seen as troublesome. In this article we
