A novel sparse coding framework with unity range codes and the possibility to produce a discriminative dictionary is presented. The framework is, in contrast to many other works, able to handle unsupervised, supervised and semi-supervised settings. Furthermore, codes are constrained to be in unity range, which is beneficial in many scenarios. The paper presents the framework and solvers used to pr
This paper provides regional GDP estimates for the 24 Swedish regions (NUTS-3) for the benchmark year 1571 and for 11 ten-year benchmarks for the period 1750-1850. The 1571 estimates are based on tax sources and agricultural statistics. The 1750-1850 estimates are produced following the widely used methodology by Geary and Stark (2002): labour force figures from population censuses at regional lev
This article analyses new waves of cultural production in the late Soviet and post-Soviet period. It focuses on contemporary artists’ self-perception and self-positioning in the new realities of the postsocialist cultural realm and national awakening discourses. Independent contemporary artists of the post-Soviet period form new artistic movements, such as Punk Shamanism in Kazakhstan, to produce
Despite of having no explicit shape model, multi-atlas approaches to image segmentation have proved to be a top-performer for several diverse datasets and imaging modalities. In this paper, we show how one can directly incorporate shape regularization into the multi-atlas framework. Unlike traditional methods, our proposed approach does not rely on label fusion on the voxel level. Instead, each re
A method using optimal control results as input to operator assist systems, automatic functions and autonomous construction machine control is presented. This method complements the vast research within autonomy to achieve the most fuel efficient solution from results that are already available from concept evaluation and system optimization in early development. The optimal control results are va
Detailed mechanisms behind regeneration after nerve injury, in particular signal transduction and the fate of Schwann cells (SCs), are poorly understood. Here, we investigated axotomy-induced activation of extracellular- signal-regulated kinase-1/2 (ERK1/2; important for proliferation) and m-calpain in vitro, and the relation to Ca2+ deletion and Schwann cell proliferation and death after rat scia

This volume is one of the outcomes of the network project In Search for Transnational Memory in Europe (ISTME), which was financed during four years 2012-2016 by a grant from COST (European Cooperation in Science and Technology) as COST Action IS1203. The Centre for European Studies (CFE) at Lund University was grant holder for ISTME, and the Centre’s Head Prof. Barbara Törnquist-Plewa was chair.
Tropomyosin-related kinase A (TrkA) receptor mediates the effects exerted by nerve growth factor on several subpopulations of neuronal cells. Ligand binding to TrkA induces receptor autophosphorylation on several tyrosine residues and the activation of signaling cascades. In this study, we describe a new site relevant for TrkA regulation, the tyrosine 701 (Y701), which is important for receptor tr
Background. Stress influences many aspects of animal behaviour and is a major factor driving populations to adapt to Changing living conditions, such as during domestication. Stress can affect offspring through non-genetic mechanisms, but recent research indicates that inherited epigenetic modifications of the genome could possibly also be involved. Methodology/Principal Findings. Red junglefowl (
The α-2-adrenergic receptor agonist brimonidine has been shown to increase survival of retinal ganglion cells following ischemic injury to the rat retina. Increased expression of growth factors has been suggested to be involved in this action. We investigated expressional changes of growth factors and their receptors following transient retinal ischemia induced by selective ligature of ophthalmic
In the present study, we have studied the expression of glial cell line-derived neurotrophic factor (GDNF) and its receptors Ret, GFRα1, and GFRα2 in the retino-tectal system before and after optic nerve transection. Using retrograde neuronal tracing in combination with in situ hybridization, we found that Ret and GFRα1 are expressed by 13-14% of the retinal ganglion cells (RGCs). These Ret-expres
