In this paper, we propose a method for estimating statistical periodicities in symbolic sequences. Different from other common approaches used for the estimation of periodicities of sequences of arbitrary, finite, symbol sets, that often map the symbolic sequence to a numerical representation, we here exploit a likelihood-based formulation in a sparse modeling framework to represent the periodic b

The expansion in the supply of energy services over the last couple of centuries has reduced the apparent importance of energy in economic growth despite energy being an essential production input. We demonstrate this by developing a simple extension of the Solow growth model, which we use to investigate 200 years of Swedish data. We find that the elasticity of substitution between a capital-labor

Erosion resulting from landslides is a serious problem in mountainous countries such as Nepal. To restore such sites it is essential to establish plant cover that protects the soil and reduces surface erosion. Mycorrhizal fungi growing in symbiosis with plants are essential in this respect because they improve both plant nutrient uptake and soil structure. We investigated the influence of organic

Floral scent is a very important trait in plant evolution. Currently, little is known about the inheritance of floral scent in cowpea (Vigna unguiculata L.) or changes that might have occurred during its domestication. Therefore, we analysed scent volatiles and molecular markers in a population of 159 F7 recombinant inbred lines derived from a cross of a domesticated blackeye cowpea cultivar, ‘524

This article theoretically analyses via scholarly literature the consequences of how the networked technology, the Internet is conceptualised. The Internet, as argued here, can be understood in many ways, in the sense that the digital environment is very much dependant on metaphors and conceptual loans to be spoken and thought of. This affects our behaviour and social norms and forms a number of l

We present spatial and dynamic information on the s = 1/2 distorted kagome antiferromagnet volborthite, Cu3V2O7(OD)(2) center dot 2D(2)O, obtained by polarized and inelastic neutron scattering. The instantaneous structure factor, S(Q), is dominated by nearest-neighbor pair correlations, with short-range order at wave vectors Q(1) = 0.65(3) angstrom(-1) and Q(2) = 1.15(5) angstrom(-1) emerging belo

Popular Abstract in Swedish Mobiltelefonanvändandet förändrades radikalt för några år sedan när de nya grafiska ”touchmobilerna” lanserades och mobilt internet blev inte bara tillgängligt utan också enkelt och använbart för alla. Idag är en ”smart-phone” i det närmaste obligatorisk i handen på såväl vuxna som ungdomar och kraven på datatakt och åtkomst är höga och ökar när allt fler samtidigt anväFor evaluation of specific antenna arrangements in wireless communication systems we need physical channel models that take into account also the directional domain of the propagation channel. In this thesis we investigate, validate and propose a practical approach to wireless channel modeling and, particularly, to mobile communication systems. For this we make the assumption that the channel can

Popular Abstract in Swedish Folkligt deltagande är något av en paroll i dagens utvecklingstänkande. När människor deltar i beslutsfattande och samhällsplanering på lokal nivå blir resultatet bättre och mer anpassat till lokala behov, särskilt i jämförelse med expertorienterade och centraliserade utvecklingsstrategier. Samtidigt kräver detta att folk i allmänhet vill delta och de har ett intresse aThe emphasis on people-centred development is distinctive in today’s development discourse. This is noticeable in catchwords like democratic decentralisation, participation, and empowerment, which are highly esteemed among NGOs, donors, and policymakers in recipient countries. The benefits of participatory approaches are several. When people influence the process of development, policies and pro

Background: Recent genome-wide association studies (GWASs) have reported several genetic variants to be reproducibly associated with type 2 diabetes. Additional variants have also been detected from a metaanalysis of three GWASs, performed in populations of European ancestry. In the present study, we evaluated the influence of 17 genetic variants from 15 candidate loci, identified in type 2 diabet

OBJECTIVEMothers of children at risk for type 1 diabetes report engaging in preventive behaviors. The purpose of this study is to further document these actions in an international, longitudinal sample and examine variables that predict whether mothers engage in these behaviors.RESEARCH DESIGN AND METHODSThis study examined an international sample (from Finland, Germany, Sweden, and the U.S.) from

Popular Abstract in Swedish Könshormon påverkar tarmrörelser Många av kroppens funktioner styrs av hormoner. Att hormoner som vi i första hand förknippar med fortplantning också skulle kunna spela en avgörande roll för tarmfunktion är dock en relativt ny upptäckt. Få saker är så viktigt för en människas välbefinnande som en välfungerande magtarmkanal. De flesta av oss tänker inte på att frukostfrThis thesis explores the relation between gonadotropin-releasing hormone (GnRH) and gastrointestinal symptoms and dysmotility. In primary Sjögren’s syndrome (pSS), a patient group with high levels of GnRH antibodies, associations between objective signs and symptoms of autonomic dysfunction (AD), impaired gastric emptying (IGE), and inflammatory and serological features were studied. Forty-three

Replicated, factorial mesocosm experiments were conducted across Europe to study the effects of nutrient enrichment and fish density on macrophytes and on periphyton chlorophyll a (chl-a) with regard to latitude. Periphyton chl-a densities and plant decline were significantly related to nutrient loading in all countries. Fish effects were significant in a few sites only, mostly because of their co

Texten fokuserar några valsituationer efter besked om obotlig cancer. Sådant som: Vem ska vi berätta för? Acceptera behandling som kemoterapi eller ej? Ta livet av sig eller ta kampen? Döva sina känslor med medicin eller sträva på med hjälpmedel som syrgas och rullator?

To improve the accuracy and transferability of molecular mechanics force fields, one needs a simple physical description of intermolecular polarization based on quantum chemistry. Ideally, in the quantum-chemical description, each molecule is treated separately and the interactions with other molecules are included as a perturbation. We propose a simple formulation of this perturbation, viz. to mo

HLA DR4-DQ8 and DR3-DQ2 haplotypes account for 89% of newly diagnosed cases of type 1 diabetes (T1D) in Sweden. The presence of a single copy of DQ6 confers protection. The aim of the present study is to evaluate whether the risk conferred by high risk HLA DR and DQ to T1D is similar in all regions of Sweden and see whether there are any significant regional differences. The subjects comprised 799
