A decomposition of the field of the wave equation in three dimensions is suggested. This wave splitting decomposes the field into two components such that in free space simple propagation properties are obtained. The inhomogeneous region is assumed to have a phase velocity variation that varies only in the radial coordinate r from the origin. The suggested wave splitting is a generalization of the

This paper reminds the analog designer of the possible stability problems encountered when simulating strongly resonating circuits in the time domain. The warping of circuit pole positions in different numerical integration algorithms is reviewed, and it is shown that all time domain simulation algorithms suffer from this effect, including Simulink, time-domain steady-state, and a harmonic balance

Wood is susceptible to decay if it is exposed to high moisture contents and certain temperatures during long periods of time. In rain exposed structures, decay often starts close to joints since the joints can act as water traps where water stays after rain events. Service life prediction models for outdoor wood structures require knowledge about the moisture and temperature conditions in the wood

Previous attempts to construct an integrative framework for personality psychology are primarily descriptions of what the field looks like today rather than analyses of its logical structure and therefore threaten to reify and perpetuate the current structure of the field. I aim here to draw attention to logically important points that may help to integrate the field and suggest potentially frui

Syftet med denna artikel är att mot bakgrund av Michel Foucaults föreläsningsserier vid Collège de France från senare delen av 1970-talet bidra till diskussionerna om innebörden, och riktigheten, av hans tes om att rättens betydelse för den offentligt sanktionerade maktutövningen har avtagit i modern tid. Undersökningen av denna tes inbegriper även ett klargörande av Foucaults förståelse av rätten

The introduction of containerization triggered complementary technological and organizational changes that revolutionized global freight transport. Despite numerous claims about the importance of containerization in stimulating international trade, econometric estimates on the effects of containerization on trade appear to be missing. Our paper fills this gap in the literature. Our key idea is to

AIMS: People with Type 1 diabetes have smaller pancreases than healthy individuals. Several diseases causing pancreatic atrophy are associated with pancreatic steatosis, but pancreatic fat in Type 1 diabetes has not been measured. This cross-sectional study aimed to compare pancreas size and fat fraction in children with Type 1 diabetes and controls.METHODS: The volume and fat fraction of the panc

Excessive production of collagen is the hallmark of fatal diseases of fibrosis such as systemic sclerosis. Overexpression of the proteoglycan fibromodulin (FMOD) has been associated with improved wound healing and scarless repair. In this study we have investigated the consequences of FMOD deficiency on the development of experimental skin fibrosis. Using immunohistochemistry, we identified FMOD i

'Sustainability' is an emerging issue that product development engineers must engage with to remain relevant, competitive and, most importantly, responsible. Yet, on examining the term 'sustainable', a plethora of definitions emerges, many of which are contradictory and confusing. This confusion and a general lack of understanding means that sustainability often gets relegated to an afterthought o
