Quantum annealing provides a promising avenue for obtaining good approximate solutions to difficult optimization problems. Protein folding represents one such problem. For testing novel algorithms and technologies, simplified lattice models are well suited, as they represent considerable computational challenges despite their simplicity. One such model is the HP model, where the protein is represe
Säljaren av en fastighet ansvarar för att fastigheten lever upp till vad som följer av köpeavtalet. För att fördela ansvaret för egenskaper som inte omfattas av avtalet har köparen belagts med vad som kan kallas för en undersökningsplikt. Köparen har inte rätt att åberopa ett fel som varit upptäckbart vid en undersökning av fastigheten. I vissa fall tillåts dock köparen åberopa ett fel trots att dThe seller of a property is liable for the property being consistent with the terms of the purchase agreement. In order to allocate liability for defects in the property not covered by the agreement, the buyer has been imposed with what can be called an obligation to examine the property. The buyer has no right to invoke a defect, which has been detectable at an examination of the property. Howeve
The paper combines a truthmaker semantics with a dispositional view of beliefs according to which they are dispositions of agents to act as if truthmakers obtain. This has a number of virtues in that it gives us (i) an exact semantics for belief reports; as well as plausible accounts of both (ii) epistemic closure and (iii) contradictory beliefs. In particular, it allows us to analyze knowledge in
The energy system is undergoing significant changes and is expected to continue to evolve. Energy demand is anticipated to increase, as is renewable energy capacity, and technical solutions are advancing. For electrical power, traditionally centralized production is increasingly complemented by distributed production, transforming fundamental system functionality. These developing factors will aff
The rat femoral artery was used as a free graft and was studied after 2, 7, 14, 30, and 60 days. The patency of the grafts was 100% (2 days, n = 6), 78% (7 days, n = 9), 63% (14 days, n = 8), 33% (30 days, n = 12), and 18% (60 days, n = 11). Histology showed an intimal thickening after 14 days and the media, which in the controls consisted of eight to ten layers of myocytes, was reduced to six to
Background Treatment of relapsing-remitting multiple sclerosis with interferon beta is only partly effective, and new more effective and safe strategies are needed. Our aim was to assess the efficacy of oral methylprednisolone as an add-on therapy to subcutaneous interferon beta-1a to reduce the yearly relapse rate in patients with relapsing-remitting multiple sclerosis. Methods NORMIMS (NORdic tr
Many industrial applications use flame impingement to obtain high heat-transfer rates. An analytical expression for the convective part of the heat transfer of a flame jet to a plate is derived. Therefore, the flame jet is approximated by a hot inert jet. In contradiction with existing convective heat-transfer relations, our analytical solution is applicable not only for large distances between the j
The Na-33 beta decay was studied online using mass separation techniques and a first description of the level structure of the neutron-rich isotope Mg-33, with N=21, has been obtained. The experiment involved the measurement of beta-gamma, beta-gamma-gamma, and beta -n-gamma coincidences as well as neutron spectra by time-of-flight technique. The first low energy level scheme for the daughter nucl
Popular Abstract in English “We are not free in this area.” This is what the iNduna, a traditional leader at KwaDapha, shared with me when we first met in August 2011. KwaDapha is a small rural community at Bhanga Nek, Kosi Bay, in northern KwaZulu-Natal/Maputaland – one of the most scenic areas on the South African coastline. Kosi Bay falls within the Coastal Forest Reserve section of the iSimaIn the past several decades under a growing influence of ecological modernisation, various assumed ‘win-win’ approaches to protected area conservation and poverty alleviation have been introduced all over the world, especially in resource-rich developing countries. Yet protected area conservation is an inherently political process, and the goals are often not achieved. There are concerns about com
Popular Abstract in Swedish Elektrostatiske vekselvirkninger mellem biomolekyler er vigtige, ikke bare i biologiske systemer, men også i flere tekniske sammenhænge. I denne afhandling studereres en række forskellige egenskaber, relevant for særligt proteiner. Således har vi ved hjælp af molekylær simulering undersøgt hvorledes proteiner vekselvirker med protoner, salte, andre peptider og proteinerElectrostatic interactions in bio-molecular systems are important not only in the living cell but also in more technical applications. Using molecular simulation as well as approximate theories the properties of a number of aqueous protein solutions have been studied. This includes interactions with other proteins, protons, charged membranes as well as flexible polyelectrolytes. The focus is on el

Context. Streaming instability is a key mechanism in planet formation, clustering pebbles into planetesimals with the help of self-gravity. It is triggered at a particular disk location where the local volume density of solids exceeds that of the gas. After their formation, planetesimals can grow into protoplanets by feeding from other planetesimals in the birth ring as well as by accreting inward
Dynamic global vegetation models (DGVMs) are important tools for modelling impacts of global change on ecosystem services. However, most models do not take full account of human land management and land use and land cover changes (LULCCs). We integrated croplands and pasture and their management and natural vegetation recovery and succession following cropland abandonment into the LPJ-GUESS DGVM.
Consumers are pushing for higher data rates to support more services that are introduced in mobile applications. As an example, a few years ago video-on-demand was only accessed through landlines, but today wireless devices are frequently used to stream video. To support this, more flexible network solutions have merged in 4G, introducing new technical problems to the mobile terminal. New techniqu
Peatlands, with high spatial variability in ecotypes and microforms, constitute a significant part of the boreal landscape and play an important role in the global carbon (C) cycle. However, the effects of this peatland heterogeneity within the boreal landscape are rarely quantified. Here, we use field-based measurements, high-resolution land cover classification, and biogeochemical and atmospheri
In recent years, several countries have started to introduce 2 + 1 roads into their road networks. Although some studies have recognized the great benefits of using 2 + 1 roads, few studies have investigated the effects of different design features of 2 + 1 roads on driver behavior and driving performance, including the type of median separation between opposing traffic flows. The overall aim of t
This chapter focuses on a specific kind of governance namely sustainability governance. Combatting climate change and social inequalities calls for governance systems specifically directed to corporate sustainability. Today our companies are fiercely working on setting up efficient systems for sustainability governance. In this chapter, the reader will learn what a sustainability governance system
