We present a polynomial time method for identifying the maximal set in excess demand at a given payoff vector. This set can be used in "large" partnership formation problems to identify the minimum element in the set of individually rational payoff vectors at which there is no overdemanded set of agents. This minimum element corresponds to the minimum Walrasian equilibrium price vector in a specia
The demographic shift is fast becoming a global challenge and an important public health concern. The proportion of people over 65 years is currently 10% around the world, but it is expected to rise to 22% by the year 2050 [1]. Populations ageing rapidly is widely seen as one of the most powerful transformative forces affecting society over the next four decades [1–4]. The ageing population is pro
Purpose City logistics projects often include urban consolidation centres (UCCs) to reduce the environmental impact of transportation by consolidating the goods flow in cities. However, there is limited knowledge about the actual environmental effects of such consolidation, e.g. in terms of number of vehicles in a city and the congestion, nuisances and emissions. The purpose of the paper is to mea
Indoor environments have a large impact on health and well-being, so it is important to understand what makes them healthy and sustainable. There is substantial knowledge on individual factors and their effects, though understanding how factors interact and what role occupants play in these interactions (both causative and receptive) is lacking. We aimed to: (i) explore interactions between factor
„White biotechnology“- the third and latest wave of biotechnology - is aiming to replace the well-established C2/C3 chemistry based on oil and gas by biological processes. The backbone of biotechnology is the conversion by fermentation which is widely established in the production of antibiotics, enzymes, bioethanol and organic acids. One of the key concepts related to “white biotechnology” are so
IntroductionIncreasing oil prices and growing environmental concerns in recent years have driven the development of renewable biofuels. Stimulated by this, the European production of bioethanol, which is produced by fermentation of sugar components in biomass, has nearly doubled in the last two years increasing from 913 million litres in 2005 to 1,565 million litres in 2006. The continuation of
BACKGROUND: Integrated health promotion improves clinical outcomes after hospital treatment. The first step towards implementing evidence-based health promotion in hospitals is to estimate the need for health promoting activities directed at hospital patients. The aim of this study was to identify the distribution and association of individual health risk factors in a Norwegian hospital population
The convergence properties of different updating methods for the multipliers in augmented Lagrangians are considered. It is assumed that the updating of the multipliers takes place after each line search of a quasi-Newton method. Two of the updating methods are shown to be linearly convergent locally, while a third method has superlinear convergence locally. Modifications of the algorithms to ensu
Proteomics, the detailed understanding of the role that proteins play in health and disease, is a necessary complement to genetic analysis. Rapid progress within the proteomics field has opened up possibilities for direct intervention in the medical and clinical area where diseases, disease progression and cause of disease can be investigated at a molecular level. This review introduces the proteo
We report the first high spectral resolution study of 17 M giants kinematically confirmed to lie within a few parsecs of the Galactic center, using R ~ 24,000 spectroscopy from Keck/NIRSPEC and a new line list for the infrared K band. We consider their luminosities and kinematics, which classify these stars as members of the older stellar population and the central cluster. We find a median metall
Established approaches to data aggregation in wirelesssensor networks (WSNs) do not cover the variety of new usecases developing with the advent of the Internet of Things. In particular,the current push towards fog computing, in which control,computation, and storage are moved to nodes close to the networkedge, induces a need to collect data at multiple sinks, ratherthan the single sink typically
This chapter introduces the system for crisis management in Sweden. Over the last century, Sweden has gone from being a poor European backwater to being among the countries with the highest human development in the world. The droughts and harsh winters that killed thousands and drove numerous Swedes to emigrate in the past are mere distractions today and the contemporary system for crisis manageme
Let R denote a connected region inside a simple polygon, P. By building barriers (typically straight-line segments) in P∖R, we want to separate from R part(s) of P of maximum area. All edges of the boundary of P are assumed to be already constructed or natural barriers. In this paper we introduce two versions of this problem. In the budget fence version the region R is static, and there is an uppe
We analyse the effect of business model innovation (BMI) on the product innovation performance of firms, based on a dynamic capabilities theoretical framework. Our empirical study is based on a large-scale representative sample of cross-industry Swedish firms participating in three waves of the Community Innovation Survey (CIS) from 2008 to 2012. We hypothesise that BMI in the form of product inno
The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitat
