Underwater terrain navigation during realistic scenarios
Many ships today rely on Global Navigation Satellite Systems (GNSS), for their navigation, where GPS (Global Positioning System) is the most well-known. Unfortunately, the GNSS systems make the ships dependent on external systems, which can be malfunctioning, be jammed or be spoofed. There is today some proposed techniques where, e.g., bottom depth measurements are compared with known maps using B
Changes in synovial fluid and serum concentrations of cartilage oligomeric matrix protein over 5 years after anterior cruciate ligament rupture : an exploratory analysis in the KANON trial
Objective: To monitor longitudinal changes of cartilage oligomeric matrix protein (COMP) in synovial fluid (sf) and serum (s) over 5 years after acute anterior cruciate ligament (ACL) rupture, and to compare results from two commercial COMP immunoassays. Design: Bio-fluids were collected from 121 patients on six occasions over 5 years after acute ACL injury, and from 25 knee healthy reference subj
Shape-texture-identification—STI—A test for tactile gnosis : Concurrent validity of STI2
Study Design: Cross-sectional study. Introduction: The shape-texture-identification (STI) test (Össur Nordic AB, Sweden) is used to evaluate one aspect of tactile gnosis in nerve disorders, and it has proven good methodological properties. Purpose of the Study: A new version of the STI test was recently introduced—STI2 (www.sensory-test.com). The purpose of this study was to test the concurrent va
Evaluation of reproducibility in MRI quantitative volumetric assessment and its role in the prediction of overall survival and progression-free survival in glioblastoma
Background: Residual tumor volume (RTV) and extent of resection (EOR) have previously been shown to affect survival in glioblastoma (GB) patients. Quantitative radiological assessment (QRA) of these factors could potentially affect clinical decision-making in the postoperative period. Purpose: The first aim was to evaluate the reproducibility of different volume estimation methods of RTV and EOR b
Learning through collaboration in the Swedish public transport sector? Co-production through guidelines and living labs
The purpose of the paper is to analyse informal collaboration in the public transport sector. Two Swedish case studies, Living lab Uddevalla and Guidelines for Regional BRT are analysed and compared concerning what kind of learning occurred and what lessons regarding informal collaboration to draw from the two cases. For both cases the analysis indicates that individual, single loop learning is th
Asymptomatic Bacteriuria is Harmless and Even Protective : Don't Treat if You Don't Have a Very Specific Reason
Symptom-free bacterial colonization of the lower urinary tract in an otherwise healthy individual was long misunderstood. Our current understanding is based on solid research proving that asymptomatic bacteriuria (ABU) is harmless and even protective against symptomatic urinary tract infection episodes. Thus, ABU should not be treated in patients with the exception of before endosurgery and, until
Rethinking steelmaking : Zero-emissions and flexibility with hydrogen direct reduction
Potential therapies and biomarkers for LAMA2-CMD. Does the microRNA hype deliver?
Laminin α2 chain-deficient muscular dystrophy, or LAMA2-CMD, is a very severe disease caused by mutations in the LAMA2 gene. Skeletal muscle is the most affected tissue, with patients presenting symptoms such as hypotonia at birth, joint contractures and progressive muscle wasting. Changes in the central nervous system include white matter abnormalities, delayed motor milestones and compromised ac

Towards zero carbon emissions – Climate policy instruments for energy intensive industries, materials and products
Energy intensive industries (EIIs), producing the basic materials and products needed in society, contribute significantly to global emissions of greenhouse gases (GHGs). Motivated by the fear of carbon leakage, climate policy has so far treated the EIIs leniently with e.g. low carbon prices and/or free allocation of emission allowances. This has not resulted in more than marginal emission abatemeEnergy intensive industries (EIIs), producing the basic materials and products needed in society, contributesignificantly to global emissions of greenhouse gases (GHGs).

From focused thought to reveries : A memory system for a conscious robot
We introduce a memory model for robots that can account for many aspects of an inner world, ranging from object permanence, episodic memory, and planning to imagination and reveries. It is modeled after neurophysiological data and includes parts of the cerebral cortex together with models of arousal systems that are relevant for consciousness. The three central components are an identification net
Influence of public bus transport organisation on the introduction of renewable fuel
The need to decrease emissions from the transport sector is getting urgent and public transport can play an important role in the transition to low emission fuels. To a large extent, public transport in Europe is provided by regional authorities who controls the traffic to a varying degree, from complete public monopoly to competitive tendering. Therefore, the aim of this paper is to analyse how t
The Relationship Between Reported Pain and Depressive Symptoms Among Adolescents
Pain and depressive symptoms are common reasons for adolescents to contact the school nurse. The aim was to describe the prevalence of pain (headache, abdominal pain, and back pain) and depressive symptoms among adolescents and to examine whether there is an association between pain and depressive symptoms. This cross-sectional survey included students (N = 639) in Sweden (median age: 16 years). O
Aromatic heterocycle galectin-1 interactions for selective single-digit nM affinity ligands
A series of 3-triazole-thiogalactosides and 3,3′-triazole-thiodigalactosides substituted with different five-membered heterocycles at the C-4 triazole position were found to have high selectivity for galectin-1. Initial studies on the 3-triazole-thiogalactosides indicated that five membered heterocycles in general gave increased affinity for galectin-1 and improved selectivity over galectin-3. The
Urban Living Labs : Catalysing Low Carbon and Sustainable Cities in Europe?
Living labs for sustainability, low carbon and smart cities that have emerged in Europe have different goals and ways of working, they are initiated by various actors, and they form different types of partnerships. There is clearly no uniform definition of living labs. Some scholars and organisations define them as partnerships between sectors (often between public, private and people) where unive
Bottom-up methodology for assessing electrification options for deep decarbonisation of industrial processes
Industrial processes currently account for a significant share (25–35 %) of the world’s total energy demand and related emis- sions. During recent years, the amount of low-carbon electric- ity from renewable energy sources (such as wind and solar) has increased continuously.

A stochastic approach to the benefit cost ratio analysis of safety treatments
Urban Living Labs Introduction
All cities face a pressing challenge - how can they provide economic prosperity and social cohesion while achieving environmental sustainability? In response, new collaborations are emerging in the form of “urban living labs” (ULL) - sites devised to design, test and learn from social and technical innovation in real time. ULL are proliferating rapidly across cities internationally as one means th
Urban Living Labs Conclusions
This book has sought to advance the theorisation of the interface between experimentation, socio-technical transitions and the city, through an internationally comparative empirical analysis of ULL. This has been structured through three core elements. First, through a set of conceptually informed empirical case studies from Africa, Asia, Europe and North America, based on original empirical work
