Authentication codes that permit arbitration are codes that unconditionally protect against deceptions from the outsiders and additionally also protect against some forms of deceptions from the insiders. Simmons introduced this authentication model and he also showed a way of constructing such codes, called the Cartesian product construction. We present a general way of constructing such codes and
Aim Understanding the driving forces and mechanisms of changes in past plant distribution and abundance will help assess the biological consequences of future climate change scenarios. The aim of this paper is to investigate whether modelled patterns of climate parameters 6000 years ago can account for the European distribution of Fagus sylvatica at that time. Consideration is also given to the ro
The Streptomyces rubiginosus xylA gene was cloned and expressed in Saccharomyces cerevisiae. No xylose isomerase activity could be detected. The produced xylose isomerase protein was insoluble and could only be recovered from cell lysates by extraction with the detergent sodium dodecyl-sulfate. In contrast, expression of the xylA gene from Thermus thermophilus in the same host strain resulted in s
The intention of this chapter is neither a pure methodological nor a theoretical discussion, but instead, an empirical analysis which aims to understand variations in perceptions of global risks and environmental concern in a number of countries. The discussion, however, relies on methodological as well as theoretical perspectives concerning the shortcomings and pitfalls one encounters in comparin
Popular Abstract in Swedish Studierna i denna avhandling behandlar hur anticancer preparatet cisplatin påverkar RNA strukturen. För att visa att strukturella förändringar kan hämma viktiga funktioner i cellen har två RNA modellsystem valts i) tRNAAla (specifikt för aminosyran alanin) från bakterien Escherichia coli och ii) en modell som representerar ett humant proteins 3' UTR (untranslated regionRNA molecules in the cellular environment have several important functions. In many cases, proper RNA function is intimately linked to proper three-dimensional structure of the molecule. Thus, it seems reasonable to assume that structural changes caused by external influence can strongly inhibit important cellular functions maintained by RNAs. Studies in this thesis have had a focus on the influen
Popular Abstract in Swedish De flesta bakterier lever i harmoni med människan, på huden och på olika slemhinnor framför allt i mag-tarmkanalen. Cellerna på dessa ytorna utgör ett effektivt skydd mot sjukdomsalstrande bakterier. Ibland bryts emellertid försvarsbarriären och bakterierna kan få tillgång till delar av kroppen som normalt är sterila. De är försvarade av fagocyter, ätarceller, som omsluStreptococcus pyogenes causes infections only in humans, from trivial tonsillitis to life-threatening conditions. One of its most important virulence factors is the M-like protein family conferring resistance to phagocytosis to the bacterium. The M-like proteins are surface exposed rod-like molecules attached to the cell wall. Each strain of S. pyogenes expresses unique M-like proteins that bind t
Positioning is a key concept in the fields of branding, marketing, and strategy. In brand management, positioning deals fundamentally with finding a balance between sameness and differentiation. Empirical research predominantly examines the effectiveness of certain strategies. Less is known about the management process and internal brand positioning dynamics. Furthermore, positioning research stil
Trellis decoding is a popular method to recover encoded information corrupted during transmission over a noisy channel. Prominent members of this class of decoding algorithms are the Viterbi algorithm, which provides maximum likelihood estimates, and the BCJR algorithm, which is a maximum a posteriori estimator commonly used in iterative decoding. In this thesis, the Viterbi algorithm is chosen si
Electrical wiring of different types of pyranose oxidase (P20) (fungal wild type, recombinant wild type with a hexahistidine tag, mutant form E542K with a hexa-histidine tag) from Trametes multicolor, and recombinant P20 from Coriolus sp. overexpressed in Escherichia coli as well as of pyranose dehydrogenase (PDH) from Agaricus meleagris and Agaricus xanthoderma with an osmium redox polymer (poly(
We cannot directly uncover the contents of our mind but we can come closer to cognitive processes via overt manifestations. I am interested in how speakers perceive, conceptualise and spontaneously describe complex pictures on higher levels of discourse and I use eye tracking methodology along with verbal protocols and a multimodal scoring method to study these mental processes. In the studies on
Popular Abstract in English Darwin’s masterpiece “On the origin of species” describes how populations (one group of individuals from the same species that can easily mate with each other and that occupy the same geographic area) evolve through the process of natural selection, which can be shortly abbreviated as the survival of the fittest. More specifically, the individuals within one population The gene (Pgi) encoding the enzyme phosphoglucose isomerase (PGI) which plays a central role in the main pathways of carbon metabolism has been shown to be of adaptive significance in a wide range of different species. Earlier studies of enzyme electromorph variation in the grass Festuca ovina suggest that variation in cytosolic PGI (PGIC) may be involved in the adaptive response of F. ovina to th
Market frictions, such as imperfect information or hassle costs, may reduce benefits from market incentives in healthcare settings. We use data from two randomised policy interventions in a Swedish region, which improved the access to provider information and reduced the switching costs of one percent of the adult population and of a sample of new residents. We examine the effects of the intervent
In the years 1941–1948, thousands of people escaped across the Baltic Sea fromeastern Europe to Sweden, primarily from the Baltic states but also from theUSSR. On the basis of newly declassified Soviet correspondence throughencrypted cables between the Soviet foreign ministry and the Soviet legationin Stockholm for the years 1944–1947, this article addresses the Soviet-Swedishdiplomatic negotiatio
The steel and chemical production industries are the largest industrial emitters of greenhouse gases in the European Union, together accounting for half of the EU’s industrial greenhouse gas (GHG) emissions. A promising strategy for achieving deep GHG emissions reductions is the electrification of these two industries, which would depend on the rapid expansion of renewable electricity supply. Such
BackgroundComplete tumor resection is the most relevant prognostic factor for overall survival in high grade serous ovarian cancer (HGSOC) patients. The current standard for classification of postoperative residual disease (RD) is surgeon´s subjective evaluation at the end of surgery. Thus, a reliable objective predictive marker is currently missing.MethodsIn this prospective single-center feasibi
We recently reported that female patients with hypopituitarism receiving controlled thyroid and steroid hormone substitution, but without GH replacement, had a more than 2-fold increase in cardiovascular mortality compared to the general population. In the present study we investigated the incidence of cardiovascular disease as well as the prevalence of cardiovascular risk factors in 33 females wi
Aim: The sweeping transformation of the biosphere by humans over the last millennia leaves only limited windows into its natural state. Much of the forests that dominated temperate and southern boreal regions have been lost and those that remain typically bear a strong imprint of forestry activities and past land-use change, which have changed forest age structure and composition. Here, we ask how
Cellulär kommunikation utvecklas ständigt; för närvarande installeras 5G-system och forskning kring 6G pågår. Tre användningsfall som diskuteras är enhanced mobile broadband (eMBB), massive machine-type communication (mMTC) och ultra-reliable low-latency communication (URLLC). För att uppfylla kraven i dessa användningsfall behövs ny teknik och en kandidat är massive multiple-input multiple-outputCellular communication is constantly evolving; currently 5G systems are being deployed and research towards 6G is ongoing.
