In hybrid zones populations that are otherwise allopatric meet and produce hybrids. One of the most well-known hybrid zones occurs throughout much of Europe between the hooded and carrion crows. Even though these species (or subspecies) of crows look very different, genetic differentiation is weak, and introgression seems to be common. In a spatial simulation that was based on empirically estimate
α-deuterated carboxylic acids have been synthesized from the corresponding malonic acids via hydrogen/deuterium exchange and decarboxylation in presence of D2O. The method is general, mild and efficient and does not require organic solvents or other additives. Yields range between 83% and 94% and purification was not necessary. Starting materials were easy accessible and the α-deuterated carboxyli
Microalgal biomass may have biostimulating effects on plants and seeds due to its phytohormonal content, and harnessing this biostimulating effect could contribute to sustainable agriculture. Two Nordic strains of freshwater microalgae species Chlorella vulgaris and Scenedesmus obliquus were each cultivated in a photobioreactor receiving untreated municipal wastewater. The algal biomass and the su
This paper proposes a ‘tool for thinking with’1: that we can describe the interaction between peopleand computers, and especially people and developer tools, as a form of conversation. We outline thisperspective, construct a work in progress analytical frame, and use it to talk about a couple of differentexamples and draw implications for future work.
This paper looks at the relationship between recurring public transport delays, accessibility to jobs, and travel behaviour in the region of Scania, Sweden. The difference between potential (scheduled) accessibility, observed (actual) accessibility, and behaviour is an important part of this research. This paper contributes to the growing body of literature that uses GTFS data (for both scheduled
Stable isotope analysis (N and C) of fossil cereal grains is regularly explored as a means of obtaining insights to past crop growing conditions and agricultural practices. In this study, we assessed how several growth conditions can affect δ15N and δ13C values of modern cereal grain with the aim to help understand isotopic values from ancient cereal remains. We investigated the impact of fertiliz
Welfare capitalism has developed in the context of rapidly expanding, fossil fuel-driven industrial economies. Faced with the urgent need for systematic changes of economic systems so that they stay within planetary limits, decoupling welfare from economic growth is an important task. This chapter introduces the concept of sustainable welfare, referring to welfare systems that prioritise the satis
Driving automation systems, including autonomous driving and advanced driver assistance, are an important safety-critical domain. Such systems often incorporate perception systems that use machine learning to analyze the vehicle environment. We explore new or differing topics and challenges experienced by practitioners in this domain, which relate to requirements engineering (RE), quality, and sys
In this introductory article, we explain the purpose of this special issue that is set up as a Festschrift in honour of the (editorial) work of BengtJohannisson. Inspired by Italo Calvino's Six Memos for the Next Millennium, the special issue is structured along six essays that are both commemorative and affirmative, that is we use the work of Johannisson to explore fresh waters and invent new pra
Many concepts for future generations of wireless communication systems use coherent processing of signals from many distributed antennas. The aim is to improve communication reliability, capacity, and energy efficiency and provide possibilities for new applications through integrated communication and sensing. The large bandwidths available in the higher bands have inspired much work regarding sen
This paper presents a simple and effective control solution to regulate temperature and humidity inside a greenhouse, which are the main climatic variables affecting crop growth and health. A multivariable control strategy with inverted decoupling is proposed in two schemes. The nighttime control scheme uses heating and dehumidification, and the daytime control scheme uses natural ventilation, deh
The current landscape of biopharmaceutical production necessitates an ever-growing set of tools to meet the demands for shorter development times and lower production costs. One path towards meeting these demands is the implementation of digital tools in the development stages. Mathematical modelling of process chromatography, one of the key unit operations in the biopharmaceutical downstream proc
At MAX IV Laboratory, the Swedish Synchrotron Radiation (SR) facility, the largest of two rings operates at 3 GeV with a bare lattice emittance of 330 pm rad. Upgrade plans are under consideration aiming at a gradual reduction of the emittance, in three stages: a short-term with an emittance reduction of 20% to 40%, a mid-term with an emittance reduction of more than 50% and a long-term with an em
Understanding the evolution of evolvability—the evolutionary potential of populations—is key to predicting adaptation to novel environments. Despite growing evidence that evolvability structures adaptation, it remains unclear how adaptation to novel environments in turn influences evolvability. Here we address the interplay between adaptation and evolvability in the peacock fly Tephritis conura, w
Due to the COVID-19 outbreak, industries have gained a thrust on contactless processing for computing technologies and industrial automation. Cloud of Things (CoT) is one of the emerging computing technologies for such applications. CoT combines the most emerging cloud computing and the Internet of Things. The development in industrial automation made them highly interdependent because the cloud c
Recognising the need for objective imaging-based technologies to assess wound healing in clinical studies, the suction blister wound model offers an easily accessible wound model that creates reproducible epidermal wounds that heal without scarring. This study provides a comprehensive methodology for implementing and evaluating photography-based imaging techniques utilising the suction blister wou
När forskare blickar ut i universum ser de överallt spåren av en stor mängd osynlig massa. Massan finns där men det går inte att se den. Ungefär 80% av all massa i universum beräknas bestå av denna "mörka materia". Det är som att mänskligheten står på stranden och blickar ut över havet utan att veta vad vatten är. I partikelfysik studeras universums minsta beståndsdelar, elementarpartiklarna, för The high event rate delivered by the Large Hadron Collider (LHC) provides experiments with opportunities for new discoveries as well as challenges related to the large amounts of data recorded. Overcoming this requires innovative techniques in the three topics of this thesis: Data acquisition, data analysis, and data compression.In the data taking period of 2015-2018, the ATLAS experiment received
The late nineteenth and early twentieth century saw a widespread interest in Asian religion within European and American esotericism. Whereas most of that interest was directed toward India, a number of representatives of the early twentieth-century esoteric environment turned toward East Asia in order to find what they hoped to be a spiritual solution to the problems of their time. One of these i
