It is of paramount importance that software reliability requirements not only can be formulated, but also enforced and evaluated before accepting a software product for release. This requires sound acceptance criteria for software, which implies that methods for evaluating the software reliability are needed during the testing phase. Thus, theoretical models which are practically applicable are ne
The Fourier dimension is not, in general, stable under finite unions of sets. Moreover, the stability of the Fourier dimension on particular pairs of sets is independent from the stability of the compact Fourier dimension.
BACKGROUND: Phosphorylation plays an essential role in regulating voltage-gated sodium (Na(v)) channels and excitability. Yet, a surprisingly limited number of kinases have been identified as regulators of Na(v) channels. We posited that glycogen synthase kinase 3 (GSK3), a critical kinase found associated with numerous brain disorders, might directly regulate neuronal Na(v) channels.METHODS: We u
The levels and conformers of alpha-synuclein are critical in the pathogenesis of Parkinson's Disease and related synucleinopathies. Homeostatic mechanisms in protein degradation and secretion have been identified as regulators of alpha-synuclein at different stages of its intracellular trafficking and transcellular propagation. Here we review pathways involved in the removal of various forms of al
There are plenty of books and articles on research methods, but few discuss the nature and purpose of method sections in academic journals. Based on interviews with critical and interpretivist researchers, this short paper examines the nature and purpose of method sections in management and organization studies. We show how researchers make sense of, and struggle with, positivist expectations abou
Given a directed graph as input, we show how to efficiently find a shortest (directed, simple) cycle on an even number of vertices. As far as we know, no polynomial-time algorithm was previously known for this problem. In fact, finding any even cycle in a directed graph in polynomial time was open for more than two decades until Robertson, Seymour, and Thomas (Ann. of Math. (2) 1999) and, independ
Risk and risk aversion are crucial concepts in finance. Models in finance typically assume a known probability distribution of returns, which does often not hold in reality. This papers aims to measure the uncertainty surrounding the probability distribution in equity markets and to evaluate if such uncertainty is priced. Our study defines uncertainty as the volatility of the option implied volati
Artificially cultivated meat may have environmental benefits and harm-reductive capabilities, making it crucial to establishing ethical food production practices. However, we argue that salient factors make producing and consuming artificially cultivated meat morally problematic. We detail some of these factors and highlight their roots in different ethical traditions. These factors present seriou
LUPREP är ett tvärvetenskapligt centrum där forskare från hela universitetet samlas för att tillsammans förklara, förstå och förbättra samhällets beredskap och resiliens. Här möts expertis inom allt från risk- och krishantering, psykologiskt försvar och underrättelseanalys till kritisk infrastruktur, civilsamhällets roll och innovation inom totalförsvaret. Genom att koppla samman forskare, myndighLUPREP is an interdisciplinary center where researchers from across the university come together to explain, understand, and improve society’s preparedness and resilience. The center brings together expertise in everything from risk and crisis management, psychological defense, and intelligence analysis to critical infrastructure, the role of civil society, and innovation within total defense.

Sudden cardiac arrest (SCA) in young athletes is rare, with an estimated incidence ranging from 0.1 to 2 per 100,000 per athlete year. The creation of SCA registries can help provide accurate data regarding incidence, treatment, and outcomes and help implement primary or secondary prevention strategies that could change the course of these events. Early cardiopulmonary resuscitation (CPR) and defi
Avdelningen arbetar med att skapa hållbara strukturer, processer och styrdokument inom processområdet vid Lunds universitet och är ett stöd till universitetsledningen i arbetsgivarpolitiska ställningstaganden. Avdelningen vägleder, utbildar och genomför insatser inom avdelningens kompetensområde: förhandling, avtal, individuell och kollektiv arbetsrätt och omställning utifrån gällande regelverk.The Division works on creating sustainable structures, processes and regulatory documents within its process area at Lund University and acts as support for the University Management regarding decision-making in employer policy matters. The Division provides guidance and training, and carries out initiatives in its area of expertise: negotiations, agreements, individual and collective labour law,
We all need to contribute to a more sustainable development – a fact that has become quite clear observing extreme weathers and diminishing fossil fuel sources. In line with the 12 Principles of Green Chemistry [1], (recommending the use of safer solvents, catalysed reactions, energy efficient processes and renewable feedstocks), research within the SuReTech program aims at developing technologies
With the concern about global warming, air pollution and energy security, the prospect of using polymer electrolyte fuel cells (PEFCs) in future sustainable and renewable energy conversion systems has achieved substantial momentum. Dimensionless numbers can be determined before construction of a model is started, to make simple estimations on the transport processes, for example, within the porous
The process streams in the forest industry contain a large amount of hemicelluloses that today ends up in the wastewater. This is an unfortunate loss of a renewable raw material. The hemicelluloses can be isolated from the process stream by using membrane filtration in a process that produces purified water as a by-product, thereby facilitating increased recirculation. However, process streams fro
Fuel production from renewable resources will likely be a prerequisite for reducing the negative anthropogenic impact on the environment and, at the same time, ensuring future energy security. In this thesis, the conversion of typical Swedish biomass, mainly Norway spruce, to ethanol was studied. The first part of the work focused on the degradation of biomass to fermentable sugars.
