We describe a simple approach to enhance vision, which is impaired by close range obscuring and/or scattering structures. Such structures may be found on a dirty windscreen of a car, or by tree branches blocking the vision of objects behind. The main idea is to spatially modulate the obscuration, either by periodically moving the detector/eye or by letting the obscuration modulate itself, such as
Competence in supply chain management (SCM) is a key factor for achieving superior business performance. The top 25 companies identified as having excellent competence in SCM in the annual research reports by AMR Research/Gartner have displayed substantially higher financial results than their competitors. In line with this cognizance, human resources are increasingly viewed as enablers of SCM and
Purpose: To explore patients’ preferred treatment outcomes during their first two years with rheumatoid arthritis (RA). Patients and Methods: A qualitative, longitudinal, multicenter study with interviews at two time points was performed in Sweden. Individual interviews were conducted at time point 1 with 31 patients with RA, defined as disease duration of ≤1 year and treatment for 3–7 months. Sev
Objective: We evaluated the claim that interventions to improve academic achievement can reduce the risk for alcohol use disorder (AUD). Method: Using nationwide data for individuals born in Sweden from 1972 to 1981 (n = 930,182), we conducted instrumental variable and co-relative analyses of the association between academic achievement and AUD with a mean 21.4-year follow-up. Our instru-ment, use
We studied avian development in 49 to 153 species of temperate and tropical New World passerine birds to determine how growth rates, and incubation and nestling periods, varied in relation to other life-history traits. We collected growth data and generated unbiased mass and tarsus growth rate estimates (mass n = 92 species, tarsus n = 49 species), and measured incubation period (n = 151) and nest
The importance of units that influence a large number of other units in a network has become increasingly recognized in the literature. In this paper we propose a new method to detect such pervasive units by basing our analysis on unit-specific residual error variances subject to suitable adjustments due to the multiple testing issues involved. Accordingly, a sequential multiple testing (SMT) proc
Carbon emissions emanating from infrastructure construction are substantial, and public infrastructure clients have begun to include carbon reduction goals in their procurement requirements. This is a new and complex field where practices vary and are still developing. Based on project documentation and interviews we map and analyze the design and implementation of carbon reduction requirements in
Down feathers are the first feather types that appear in both the phylogenetic and the ontogenetic history of birds. Although it is widely acknowledged that the primary function of downy elements is insulation, little is known about the interspecific variability in the structural morphology of these feathers, and the environmental factors that have influenced their evolution. Here, we collected sa
Answering the key challenges for society due to environmental issues like climate change, pollution and loss of biodiversity, and making the right decisions to tackle these in a cost-efficient and sustainable way requires scientific understanding of the Earth System. This scientific knowledge can then be used to inform the general public and policymakers. Scientific understanding starts with havin
Investigations of social-genetic effects, whereby a social partner’s genotype affects another’s outcomes, can be confounded by the influence of the social partner’s rearing environment. We used marital information on more than 300,000 couples from Swedish national data to disentangle social-genetic from rearing-environment effects for alcohol use disorder (AUD). Using observational and extended-fa
My research engages with the varieties of relationship between verbal and non-verbal forms of language and communication. I approach the issue through three people who live or work with non-verbal people on the autistic spectrum: Phoebe Caldwell, Fernand Deligny and Iris Johansson. Their practices bring singular perspectives to my core question: How can we (re)conceive and engage with non-verbal f
Remote sensing has evolved to become a key tool for various fields of environmental analysis, thus actively informing policy across areas and domains. To evaluate the degree to which remote sensing is contributing to the science of ecologically-oriented urban planning, we carried out a systematic literature review using the SCOPUS database, searching for articles integrating knowledge in urban pla
The purpose of the paper is to explore knowledge accumulation in research on pedagogy in entrepreneurship education, with particular attention to how core journal outlets, core topics and core scholarly works have developed over time. The authors combine a systematic literature review technique and bibliometric analysis to depict the development of this stream of research in the period 1995–2018. The purpose of the paper is to explore knowledge accumulation in research on pedagogy in entrepreneurship education, with particular attention to how core journal outlets, core topics and core scholarly works have developed over time. The authors combine a systematic literature review technique and bibliometric analysis Findings from the analyses suggests that research addressing pedagogy in entre
Short analysis of the experimental film "Little Dog for Roger" (1967) by British artist and filmmaker Malcolm Le Grice (b. 1940).
AIMS: Metabolic derangement is implicated in the pathophysiology of heart failure (HF) and pulmonary hypertension (PH). We aimed to identify the dynamics of metabolic plasma proteins linked to end-stage HF and associated PH in relation to haemodynamics, before and after heart transplantation (HT).METHODS AND RESULTS: Twenty-one metabolic plasma proteins were analysed with proximity extension assay
Anna Rydstedts dikter undersöks med Johannesevangeliets markanta motsats mellan världen och Gud, som raster. Till denna motsats fogas motsatserna ljus- mörker, själ/ande - kropp/materia, liv- död. Därtill uppmärksammas det tydliga semiotiska karaktär som Johannesevangeliet har: under är inte bara under, utan också och framförallt tecken. Det visar sig att Rydstedts dikter ofta byggs av dessa motsa
PURPOSE: Photoacoustic (PA) imaging has the potential to become a non-invasive diagnostic tool for giant cell arteritis, as shown in pilot experiments on seven patients undergoing surgery. Here, we present a detailed evaluation of the safety regarding visual function and patient tolerability in healthy subjects, and define the spectral signature in the healthy temporal artery.METHODS: Photoacousti
BACKGROUND: H-plasty reconstructive surgery is commonly used to close defects after tumor excision in the periorbital region. Revascularization of the bipedicle skin flaps is essential for healing. However, it has not previously been possible to study this revascularization in humans due to the lack of noninvasive perfusion monitoring techniques. The aim was to monitor perfusion in H-plasty flaps
