Objective Deconvolution is an ill-posed inverse problem that tends to yield non-physiological residue functions R(t) indynamic susceptibility contrast magnetic resonance imaging (DSC-MRI). In this study, the use of Bézier curves is proposedfor obtaining physiologically reasonable residue functions in perfusion MRI.Materials and methods Cubic Bézier curves were employed, ensuring R(0)=1, bounded-in

While striving for more competitive products as well as reaching the Global Sustainable Development Goals, automotive powertrain manufacturers increase the demands on gears, which translates to decreased manufacturing error tolerances. Too tight tolerances may, however, counteract the goal if it leads to increased material and energy consumption due to unjustified scrapping. This paper presents a

Det pågår förändringar i våra kyrkor. Krav och behov på användande av gudstjänstrum leder till ändringar och ibland omfattande omgestaltningar. Föreliggande rapport är ett resultat av en studie som fokuserar påförändringsprocesser kopplade till sittmöbler i Svenska kyrkan, närmare bestämt bänkar och stolar avsedda för församlingen. Våra exempel är hämtade från nyligen genomförda eller pågående sit

INTRODUCTION: A reliable electrocardiographic predictor of ventricular fibrillation (VF) in patients with ST elevation myocardial infarction (STEMI) is lacking so far. Previous experimental/simulation study suggested a terminal T-wave inversion (TTWI) in ischemia-related ECG leads corresponding to anterior infarct localization as an independent predictor of reperfusion VF (rVF). This T-wave charac

Klassiker är ett komplext fenomen. Dynamiskt och svårfångat. Artikeln undersöker hur en modern möbelklassiker skapas Begreppet kan laddas med värden av både immateriell och materiell karaktär. Auraproduktion fyller möbeln med innehåll och stärker den som objekt, vilket gör det till ett operativt och flitigt använt epitet inom både kommersiell och kulturell verksamhet. I artikeln lyfts exempel på p

IntroductionAs the pandemic continues to spread, more knowledge is needed about the viral transmission routes. Several super spreading events during the Covid-19 pandemic have been linked to singing in choirs and talking loud. However, in the beginning of the pandemic there was only one study about emitted aerosols and droplets from singing, published in 1968, and only a handful on emissions from

In the beginning of the COVID-19 pandemic, several super spreader events occurred during choir singing, which lead to an increased attention to airborne transmission of SARS-CoV-2. Since then, aerosol generation from singing has been studied in detail, however, mainly from healthy subjects. In this study, we collected aerosol particles in the exhaled breath of 38 COVID-19 infected patients during
