Despite its present shortage, He-3 continues to be the most common neutron converter for detectors in neutron scattering science. However, it is obvious that the development of large area neutron detectors based on alternative neutron converters is rapidly becoming a matter of urgency. In the technique presented here, grids each comprising 28 (B4C)-B-10 layers ( each 1 mu m thick) are used to conv
In this paper we discuss new adaptive proposal strategies for sequential Monte Carlo algorithms—also known as particle filters—relying on criteria evaluating the quality of the proposed particles. The choice of the proposal distribution is a major concern and can dramatically influence the quality of the estimates. Thus, we show how the long-used coefficient of variation (suggested by Kong et al.
Background: Proteases of human pathogens are becoming increasingly important drug targets, hence it is necessary to understand their substrate specificity and to interpret this knowledge in practically useful ways. New methods are being developed that produce large amounts of cleavage information for individual proteases and some have been applied to extract cleavage rules from data. However, the
Nominally Anhydrous Minerals (NAM) in the Earth's mantle contain trace amounts of hydrogen, as a result of the NAM's ability to incorporate hydroxyl ions. The isotopic composition of these hydrogen reservoirs is for the Earth's crust, well characterized. The knowledge of the isotopic composition of the Earth's interior on the other hand is limited. It is believed that the hydrogen composition in t
OBJECTIVE - Insulinoma-associated protein 2 (IA-2) is a major autoantigen in type I diabetes, and IA-2 autoantibodies are routinely detected by a liquid-phase radioimmunoprecipitation assay. The present experiments were initiated to develop a new assay that does not require the use of radioisotopes or autoantigens prepared in bacteria or by in vitro transcription/translation. RESEARCH DESIGN AND M
Purpose: According to literature there is a set of six key competencies that distinguish sustainability professionals, including researchers, from professionals and researchers in other fields, making them “systemic problem solvers, change agents, and transition managers”. However, there is lack of empirical evidence, first, that these skills are necessary and sufficient for sustainability problem
In this paper regularization of the correlation matrix between futures contracts is examined. With starting point in the recently established HPCA framework (Avellaneda, 2019), a couple of different extensions to the one-factor model is suggested. Extensions are made in terms of adjusting the model according to different cluster structures. The data consists of futures contracts on a wide variety
China’s economic development has not only led to enormous growth figures, but also to a severe degradation of the environment. Mass-consumption of fossil fuels like oil and coal in China contributed to reaching the level of the largest greenhouse gas emitter worldwide. For the Chinese government to react, it is crucial to take the electricity purchase decisions of households into account to succes
Housing expenditure is without doubt one of the biggest expenditure posts for all households. By using econometrics to estimate regressions with cross-‐sectional data including more than 1500 individuals, this thesis examines whether there is any individual characteristics that determines how big a share of the disposable income that is spent on housing each month. The results indicate that diffe
The global production and use of plastic is increasing and a substantial part will end up in aquatic environments where it will degrade into micro- and nanoplastic particles (NPPs). NPPs will interact with naturally occurring biomolecules present in aquatic environments which in turn will affect the properties of the particles. The purpose of this study was thus to investigate how organic matter a
A new development within the high spin Nilsson-Strutinsky formalism presented and applied to certain sd-shell nuclei. The previous method of calculating potential-energy surfaces as a function of angular momentum using interpolated spin values is not satisfactory when studying the individual bands for these light nuclei. In the present research, manyparticle many-hole excitations are considered in

Klimatförändringar orsakade av antropogena faktorer har en ökande effekt på både naturliga och humana system. Klimatförändringar bidrar till en förändring av varaktigheten, frekvensen och intensiteten av extrema väderhändelser (som till exempel stormar, översvämningar och värmeböljor). Några exempel på konsekvenser från klimatförändringar på de humana systemen är förlust av liv, förlust av egendomThe changing climate caused by anthropogenic factors has an increasing effect on natural and human systems. There is therefore an increasing need for society to adapt to the effects of climate change (IPCC, 2012; Rescalvo et al., 2013) This is vital since the effects of climate change are already being noticed in many parts of the world (Rescalvo et al., 2013). However, municipalities in Sweden ge
This thesis investigates the use of several acceleration schemes to improve the performance of the primal-dual hybrid gradient algorithm for linear programming (PDLP), a state-of-the-art first-order method for linear programming (LP). The three main acceleration schemes investigated are: Polyak heavy ball momentum, Nesterov acceleration, and steering vectors selected in a residual momentum directi
Innovation concentrations are increasingly extending beyond metropolitan cores into urban peripheries through science parks, research infrastructures, advanced manufacturing sites, and innovation districts. Yet their physical presence does not necessarily generate long-term local development capacity. Existing research has explained innovation stability largely through agglomeration, proximity, in
Brädspel blir alltmer populära, vilket gör det ännu viktigare att deras regelböcker går att läsa och förstå. Denna uppsats syftar till att analysera språkbruket i strategiska brädspel i förhållande till klarspråk och forskning om instruerande text, men också att undersöka spelarnas uppfattning om spelens regelböcker. Metoden för undersökningen består av en textanalys av spelen Terraforming Mars, R
This thesis explores how large manufacturing companies in the Benelux region make sense of climate resilience and what they perceive as its key elements. Although ‘corporate climate resilience’ has gained increasing attention in academic and practitioner-oriented literature, the concept is characterised by ambiguity and fragmentation, resulting in inconsistent corporate interpretations and practic
Morbidity and mortality resulting from acute and subsequently chronic graft-versus-host disease (GVHD) pose a serious challenge to wider applicability of allogeneic stem cell transplantation (SCT). Mycophenolate mofetil (MMF) is a widely used drug in combination with a calcineurin inhibitor and often cyclosporine (CsA), in preventing GVHD. The use of MMF for acute GVHD (aGVHD) prophylaxis appears
