Tracking visual segmentation : connecting semiotic and cognitive perspectives
This article introduces a new methodology for deriving the dynamics of visual segmentation in relation to the underlying cognitive processes involved. The method combines social semiotics approaches to visual segmentation with eye-tracking studies on authentic image viewing and simultaneous image description. The authors' thesis is that visual segmentation suggested by the social semiotic approach
Governance of Biofuels for Transport in Europe: Lessons from Sweden and the UK
Biofuels for transport are attracting considerable support from the European Union. However, the complexity of the biofuels industry and the diversity of actors create significant challenges for policy-making and governance. This paper explores the role of governance in the development of the biofuels industry in Europe focusing on Sweden and the UK. The purpose of this paper is to investigate the
On the evolutionary stability of partial migration.
The evolution of partial migration in birds is typically assumed to be the result of an optimization process. The fitness rewards for individuals choosing to migrate are balanced against the rewards of remaining in the breeding area all year around. This balancing is often thought to result in an evolutionarily stable strategy (ESS) such that an optimal fraction of the population becomes migratory
The glucagon-like peptide 1 receptor agonist liraglutide attenuates the reinforcing properties of alcohol in rodents.
The incretin hormone, glucagon-like peptide 1 (GLP-1), regulates gastric emptying, glucose-dependent stimulation of insulin secretion and glucagon release, and GLP-1 analogs are therefore approved for treatment of type II diabetes. GLP-1 receptors are expressed in reward-related areas such as the ventral tegmental area and nucleus accumbens, and GLP-1 was recently shown to regulate several alcohol
Sulfonated poly(arylene ether sulfone) ionomers containing di- and tetrasulfonated arylene sulfone segments
Poly(arylene ether sulfone) (PSU) ionomers containing disulfonated aryl-SO2-aryl and tetrasulfonated aryl-SO2-aryl-aryl-SO2-aryl segments, respectively, were synthesized and studied to establish their structure–property relationships as proton-exchange membranes. High molecular weight PSUs with different distributions of sulfone bridges in the backbone were prepared by nucleophilic aromatic substi
Determination of spatially dependent diffusion parameters in bovine bone using Kalman filter.
Although many studies have been made for homogenous constant diffusion, bone is an inhomogeneous material. It has been suggested that bone porosity decreases from the inner boundaries to the outer boundaries of the long bones. The diffusivity of substances in the bone matrix is believed to increase as the bone porosity increases. In this study, an experimental set up is used where bovine bone samp
Mechanistic modelling of drug release from a polymer matrix using magnetic resonance microimaging.
In this paper a new model describing drug release from a polymer matrix tablet is presented. The utilization of the model is described as a two step process where, initially, polymer parameters are obtained from a previously published pure polymer dissolution model. The results are then combined with drug parameters obtained from literature data in the new model to predict solvent and drug concent
Trade-offs between bird diversity and abundance, yields and revenue in smallholder oil palm plantations in Sumatra, Indonesia
Global land-use change has drastic consequences for biodiversity leading to losses of ecological functioning, ecosystem services and human well-being. While species dependent on undisturbed natural habitat are most affected by conversion to agriculture, even populations of disturbance-tolerant species can be endangered in landscapes dominated by high-input mono-cultural cropping systems. This has
Reversible clustering of sodium channels at the spike is driven by a local crystallization/melting transition around bilayer rafts
The classical theory of nerve signal conduction, introduced half a century ago by Hodgkin and Huxley, was challenged in 2005 by the so called soliton theory introduced by Heimburg and Jackson. This latter theory is based on a bilayer phase transition forming a mechanical wave, involving a transition from a disordered conformation of the bilayer into the gel-state, and the electric pulse is regarde
A survey on the integration of product and package development
Increased efficiency and effectiveness in the product life cycle can be expected to result from extending the product development process to include the simultaneous development of the package. In this paper, three surveys performed in the Swedish mechanical, pharmaceutical and food industries are supplemented to describe the interest of such a concept in industry. This paper reveals that both the
Social and Healthcare Professionals' Experiences of Giving Support to Families Where the Mother Has an Intellectual Disability: Focus on Children
Families where the mother has an intellectual disability need support to counteract possible detrimental life circumstances for the children involved. The aim of this study was to describe social and healthcare professionals' experiences of providing support for families with maternal intellectual disability and specifically focused on if and how they believed the support practices benefited the c
Second malignancies following treatment of chronic myeloid leukaemia in the tyrosine kinase inhibitor era
Given that tyrosine kinase inhibitors (TKIs) have dramatically improved the survival of patients with chronic myeloid leukaemia (CML), we were interested in examining the possible risk of long-term adverse events, such as the emergence of other neoplasms. Therefore, we studied the development of second malignancies in 868 patients diagnosed with CML between 2002 and 2011 using the Swedish CML regi

Carbon storage in the organic layers of boreal forest soils under various moisture conditions: A model study for Northern Sweden sites
A typical feature of the boreal forest landscape is a gradient from dry to wet sites, with associated increases in the depth of the soil organic layers. In this study, the coupled ecosystem-soil biogeochemistry model GUESS-ROMUL is used to explore how the specific features of soil organic matter decomposition and vegetation dynamics account for an observed difference between the soils formed under
Immunoregulatory differences between adult onset type 1 diabetes and latent autoimmune diabetes in adults (LADA)
Popular Abstract in Swedish Autoimmun diabetes karakteriseras av cell medierad autoimmunitet mot insulinproducerande beta celler i Langerhanska öar. Typ 1 diabetes är den största typen av diabetes i barn och ungdomar och antas vara orsakad av Th1-cell drivet angrepp av beta celler. Den betydligt vanligare typ 2 diabetes antas inte vara en autoimmun sjukdom men diabetes specifika autoantikroppar (IAutoimmune diabetes is characterized by cell mediated autoimmunity against insulin producing beta cells in pancreatic islets. Type 1 diabetes is the major cause of diabetes in children and adolescents and is believed to be mediated by a Thl driven destruction of beta cells. The much more prevalent type 2 diabetes is not considered as an autoimmune disease but diabetes specific autoantibodies (ICA
Stability for the periodic Camassa-Holm equation
We use integrability to prove the stability of smooth periodic solutions of the Camassa-Holm equation. In particular, the smooth periodic traveling wave solutions are shown to be orbitally stable.
Positive-energy one-particle levels in quadrupole-deformed Woods-Saxon potentials
Positive-energy one-particle levels for neutrons in Y20 deformed Woods-Saxon potentials are examined using the eigenphase representation. Taking the example of =1/2+ levels, not only one-particle resonant levels but also all solutions in the eigenphase representation within a model space are studied. It is shown that a particular eigenphase solution among an infinite number of eigenphase solutions
Molecular nature of resonant x-ray scattering in solid LiNO3
Resonant x-ray emission spectroscopy has been applied to study radiative decay processes following the N 1s near-edge excitations in solid LiNO3. It has been shown that the origin of both nonresonant and resonant spectra are essentially molecular, their shape being primarily determined by the electron transitions between molecular orbitals of the quasiisolated NO3- anion. A strong low-energy sideb
Regulation of Ca2+ channel and phosphatase activities by polyamines in intestinal and vascular smooth muscle - implications for cellular growth and contractility.
Polyamines added extracellularly to intestinal and vascular smooth muscle cells cause relaxation through inhibition of Ca2+ channel activity. Intracellularly applied polyamines also affect Ca2+ channel properties. Polyamines do not readily pass over the plasma membrane because of their positive charges but in permeabilized smooth muscle preparations they have free access to the cytoplasm. In this
