A Multisensory Approach to Rock Art : Exploring Tactile and Visual Dimensions in the Southern Scandinavian Rock Art Tradition

This paper discusses rock art in southern Scandinavia as a multisensory format, where both sight and touch would have contributed to the comprehension of the images. From a structural semiotic point of view, we suggest that rock art can be construed as an organised set of features, such as visual and tactile elements, organised into heterogeneous unities with dynamic relations between elements tha

A proposed amendment to the current guidelines for mild traumatic brain injury : reducing computerized tomographies while maintaining safety

Purpose: Head trauma is a common complaint in emergency departments. Identifying patients with serious injuries can be difficult and generates many computerized tomographies. Reducing the number of computerized tomographies decreases both cost and radiation exposure. The aim of this study was to evaluate whether the current Scandinavian Neurotrauma Committee guidelines could be revised in such a w

Development of the PREMature Infant Index (PREMII™), a clinician-reported outcome measure assessing functional status of extremely preterm infants

Background: Comprehensive measures to evaluate the effectiveness of medical interventions in extremely preterm infants are lacking. Although length of stay is used as an indicator of overall health among preterm infants in clinical studies, it is confounded by nonmedical factors (e.g. parental readiness and availability of home nursing support). Objectives: To develop the PREMature Infant Index (P

Automatic discovery of resource-restricted Convolutional Neural Network topologies for myoelectric pattern recognition

Convolutional Neural Networks (CNNs) have been subject to extensive attention in the pattern recognition literature due to unprecedented performance in tasks of information extraction from unstructured data. Whereas available methods for supervised training of a CNN with a given network topology are well-defined with rigorous theoretical justification, procedures for the initial selection of topol

Detection of Needle Dislodgement Using Extracorporeal Pressure Signals : A Feasibility Study

Venous needle dislodgement (VND) during dialysis is a rarely occurring adverse event, which becomes life-threatening if not handled promptly. Because the standard venous pressure alarm, implemented in most dialysis machines, has low sensitivity, a novel approach using extracted cardiac information to detect needle dislodgement is proposed. Four features are extracted from the arterial and venous p

Geophysical investigation of glass ‘hotspots’ in glass dumps as potential secondary raw material sources

This study investigates the potential for Electrical Resistivity Tomography (ERT) to detect buried glass ‘hotspots’ in a glass waste dump based on results from an open glass dump investigated initially. This detection potential is vital for excavation and later use of buried materials as secondary resources. After ERT, test pits (TPs) were excavated around suspected glass hotspots and physico-chem

CURRENT CONCEPTS AND MODALITIES FOR MONITORING THE FELLOW EYE IN NEOVASCULAR AGE-RELATED MACULAR DEGENERATION : An Expert Panel Consensus

PURPOSE: The presence of neovascular age-related macular degeneration (nAMD) in one eye is a major risk factor for the development of disease in the fellow eye. Several methods exist to help physicians monitor the fellow eye, with new technologies becoming increasingly available. METHODS: We provide an overview of modalities for nAMD monitoring, including advances in home-based options, and review

An approach to modeling bike-sharing systems based on spatial equity concept

Efficient and sustainable mobility is becoming a need for emerging metropolitan areas, essential to grant their attractiveness, quality of life and economic power. Among the possible strategies to adopt, shared mobility systems have proven to be a valuable alternative to accommodate the mobility needs of citizens ensuring at the same time sustainability and transport flexibility. In particular, th

Unpacking the role of universities in the emergence, development and impact of social innovations – A systematic review of the literature

Widening income and knowledge inqualities have led to growing expectations for universities to integrate social innovation in their core missions as a response to societal problems.This systematic review of literatureprovides an overview of the state-of-the-art of knowledge on the role of the university in enabling social innovation through its missions of teaching, research and third mission. It

Diabetes mellitus as a risk factor for compression neuropathy: a longitudinal cohort study from southern Sweden

Introduction Compression neuropathies (CN) in the upper extremity, the most common being carpal tunnel syndrome (CTS) and ulnar nerve entrapment (UNE), are frequent among patients with diabetes mellitus (DM). Earlier studies have shown contradicting results regarding DM as a risk factor for CN. Thus, the aim of the present population-based, longitudinal study was to explore potential associations

Technology characteristics and catching-up policies: solar energy technologies in Mexico

Developing countries are giving increasing attention to industry development in renewable energy industries. Previous research highlights the influence of technology characteristics on such catching-up policies, distinguishing between complex products produced in small batches, and mass-produced simple products. We suggest that catching-up policies should move beyond this binary distinction betwee

An Increasing Trend in the Prevalence of Polypharmacy in Sweden : A Nationwide Register-Based Study

Aim: Polypharmacy is becoming a global health problem. The aims of this study were to evaluate the temporal trends in the prevalence of polypharmacy in Sweden and to explore polypharmacy disparities by age, gender, education, and immigration status. Methods: Polypharmacy and excessive polypharmacy were evaluated using data extracted from the Swedish Prescribed Drug Register between 2006 and 2014.

A voluntary simplicity lifestyle : Values, adoption, practices and effects

Adopting a voluntary simplicity lifestyle (VSL) contributes to a change in consumption patterns towards more sustainable ones, which is urgently needed. This study defines the VSL as a voluntary reduction of income and consumption in exchange for more free time. Our research aims to contribute with more detailed VSL criteria. A literature review develops initial VSL criteria, which are validated a

Mutations in SULT2B1 Cause Autosomal-Recessive Congenital Ichthyosis in Humans

Ichthyoses are a clinically and genetically heterogeneous group of genodermatoses associated with abnormal scaling of the skin over the whole body. Mutations in nine genes are known to cause non-syndromic forms of autosomal-recessive congenital ichthyosis (ARCI). However, not all genetic causes for ARCI have been discovered to date. Using whole-exome sequencing (WES) and multigene panel screening,

Whose responsibility is medication reconciliation : Physicians, pharmacists or nurses? A survey in an academic tertiary care hospital

Background: Medication errors occur frequently at transitions in care and can result in morbidity and mortality. Medication reconciliation is a recognized hospital accreditation requirement and designed to limit errors in transitions in care. Objectives: To identify beliefs, perceived roles and responsibilities of physicians, pharmacists and nurses prior to the implementation of a standardized med

Organotypic slice culture model demonstrates inter-neuronal spreading of alpha-synuclein aggregates

Here we describe the use of an organotypic hippocampal slice model for studying α-synuclein aggregation and inter-neuronal spreading initiated by microinjection of pre-formed α-synuclein fibrils (PFFs). PFF injection at dentate gyrus (DG) templates the formation of endogenous α-synuclein aggregates in axons and cell bodies of this region that spread to CA3 and CA1 regions. Aggregates are insoluble

Different climate scenarios alter dominance patterns among aquatic primary producers in temperate systems

In a future climate change perspective, the interactions among different life-forms of primary producers will likely be altered, leading to changes in the relative dominance among macrophytes, filamentous, and planktonic algae. In order to improve the possibilities to forecast future ecosystem services and function, we therefore conducted a long-term mesocosm study where primary producers were exp
