Recent evidence indicates experience-dependent brain volume changes in humans, but the functional and histological nature of such changes is unknown. Here, we report that adult men performing a cognitively demanding spatial navigation task every other day over 4 months display increases in hippocampal N-acetylaspartate (NAA) as measured with magnetic resonance spectroscopy. Unlike measures of brai
The chapter explores the potentials of a new type of pedagogical agent – a Challenger Teachable Agent. The aim of such a pedagogical agent is to increase engagement and motivation, and challenge students into deeper learning and metacognitive reasoning. It is based on the successful implementation of the Learning by Teaching approach in Teacheable Agents, and in addition it draws on previous work
Climate-herbivory interactions have been largely debated vis-à-vis ecosystem carbon sequestration. However, invertebrate herbivores also modify emissions of plant biogenic volatile organic compounds (BVOCs). Over the shorter term, they do this by the induction of de novo synthesis of a plethora of compounds; but invertebrates also affect the relative proportions of constitutively BVOCs-emitting pl
In this work we have developed InAs nanowire templates, with designed zinc blende and wurtzite segments, for selective growth of radial GaSb heterostructures using metal organic vapor phase epitaxy. We find that the radial growth rate of GaSb is determined by the crystal phase of InAs, and that growth is suppressed on InAs segments with a pure wurtzite crystal phase. The morphology and the thickne
Secure base scripts (SBS) are thought of as the earliest, rudimentary mental representations of attachment, comprising temporally and causally related events occurring in interactions between children and their attachment figures. SBS have been studied in preschool children, adolescents and adults, but there is little research relating SBS to other attachment measures in middle childhood. Here, th
AimTo describe the associations between positive and negative reactions of informal caregivers of people with dementia and health outcomes across eight European Countries. BackgroundCaring for someone with dementia may have implications for the caregiver's own health and for the care recipient. These consequences could be associated with caregivers' reactions to the process of care. DesignAssociat
In this paper, we describe a novel approach to create 3D miniatures of persons using a Kinect sensor and a 3D color printer. To achieve this, we acquire color and depth images while the person is rotating on a swivel chair. We represent the model with a signed distance function which is updated and visualized as the images are captured for immediate feedback. Our approach automatically fills small
The article focuses on a case of rewriting of a short episode in the narrative of Erri De Luca. It is all about a cry: in 1930, in the harbour of Naples, an anonymous woman who is watching the departure of a ship suddenly cries out the name of Salvatore, probably her son being on the ship to emigrate to America. This episode, narrated in the tale “Udito: un grido” first published 1993, returns wit
Lyme borreliosis (LB) is a common and increasing tick-borne disease in Europe. The risk of acquiring a Borrelia infection after a tick bite is not fully known. Therefore, we investigated the incidence of Borrelia infection after a bite by a Borrelia-infected tick and if the Borrelia load and/or the duration of tick-feeding influenced the risk of infection. During 2008-2009, ticks and blood samples
Aim. The aim of this study was to compare preoperative patient evaluation by a vascular physician with a standardized workup protocol prior to elective endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA), in terms of differences in patient medication and mortality. Methods. Consecutive patients with infrarenal AAA treated with standard EVAR from 1998 to 2006 (group 2) and 2007
Climate reconstructions from data sensitive to past climates provide estimates of what these climates were like. Comparing these reconstructions with simulations from climate models allows to validate the models used for future climate prediction. It has been shown that for fossil pollen data, gaining estimates by inverting a vegetation model allows inclusion of past changes in carbon dioxide valu
A process combining dark fermentation and photofermentation for production of hydrogen is interesting due to its potential of producing hydrogen at a high yields. In this study, the hydrogen process is compared to a 2nd generation ethanol process with respect to cost and with the aim of increasing our understanding of the pros and cons and giving a clear picture of the present status of the two pr
Here, we summarise the results after carrying out a large survey regarding the assessment of vascular alterations, both vessel changes and vascular lesions in an inter-laboratory setting. In total, 32 neuropathologists from 22 centres, most being members of BrainNet Europe (BNE), participated by filling out a questionnaire with emphasis on assessment of common vascular alterations seen in the brai
Aim: To study the effects of intravitreally injected triamcinolone acetonide (TA) and/or its preservative benzyl alcohol (BA) in healthy rabbit retina. Methods: Forty-eight rabbits (aged 4 months, body weight approximate to 3 kg) were randomized into four groups (n=12). They were examined with electroretinography (ERG) prior to drug exposure, and then injected intravitreally with a combination of
The relationship between non-radiographic axial spondyloarthritis (nr-axSpA) and ankylosing spondylitis (AS) is currently debated. Using observational data from the South Swedish Arthritis Treatment Group register, we thus aimed to compare clinical development and treatment adherence between nr-axSpA and AS patients during three years of anti-TNF (tumor necrosis factor) therapy in clinical practic
A detailed study has been made of soot growth in two premixed flat ethylene/air flames, at I broken vertical bar = 2.1 and I broken vertical bar = 2.3, where focus has been on following the change in optical properties from nascent to more mature soot, and the importance of these properties for laser-induced incandescence (LII). A combination of two-color LII (2C-LII) and elastic light scattering
We present new geochemical data for three Mesoarchaean supracrustal belts (Ravns Storo, Bjornesund and Perserajoorsuaq) situated north of Frederikshab Isblink in southern West Greenland for which we propose the collective name 'The Ikkattup Nunaa Supracrustal Association'. They comprise mainly amphibolites of tholeiitic basalt composition and leucoamphibolites of calc-alkaline andesite composition
An integral equation based scheme is presented for the fast and accurate computation of effective conductivities of two-component checkerboard-like composites with complicated unit cells at very high contrast ratios. The scheme extends recent work on multi-component checkerboards at medium contrast ratios. General improvement include the simplification of a long-range preconditioner, the use of a
