BACKGROUND: A new generation of positron emission tomography with computed tomography (PET-CT) was recently introduced using silicon (Si) photomultiplier (PM)-based technology. Our aim was to compare the image quality and diagnostic performance of a SiPM-based PET-CT (Discovery MI; GE Healthcare, Milwaukee, WI, USA) with a time-of-flight PET-CT scanner with a conventional PM detector (Gemini TF; P

Sweden went back to gold at the pre‐war parity, whereas Finland returned at the existing rate, accepting the depreciation of the markka that had occurred over the war and early post‐war years. The authors use a quantity‐theory framework to investigate the results of the divergent exchange rate and monetary policies followed by the two countries. The Swedish economy was forced to undergo a severe c

Many innovations arise spontaneously as a result of the market mechanism and the actions of capitalist firms, but some, especially the more radical ones, require public intervention. The first part of this chapter discusses when such policy interventions might be necessary and why. The next section discusses selectivity in innovation policy. The last (main) section of the chapter discusses the gen

The two pyrazolopyridines, etazolate (SQ20009) and cartazolate (SQ65396), enhance the binding of [3H]diazepam to benzodiazepine receptor sites in rat brain. This enhancement is due to a change in affinity without a change in maximal binding. Pentobarbital also enhances [3H]diazepam binding by lowering the K(D). Pentobarbital gives a maximal enhancement of benzodiazepine binding slightly greater th

Wide-angle neutron scattering experiments combined with empirical potential structural refinement modeling have been used to study the detailed structure of decyltrimethylammonium bromide micelles in the presence of acid solutions of HCl or HBr. These experiments demonstrate considerable variation in micelle structure and water structuring between micelles in the two acid solutions and in comparis

By being predicated on supervised machine learning, pattern recognition approaches to myoelectric prosthesis control require electromyography (EMG) training data collected concurrently with every detectable motion. Within this framework, calibration protocols for simultaneous control of multifunctional prosthetic hands rapidly become prohibitively long - the number of unique motions grows geometri

BACKGROUND AND AIM: Syncope is a common condition with many possible causes, ranging from benign to life-threatening aetiologies. Establishing a diagnosis can be difficult and specialized syncope units, using cardiovascular autonomic tests (CAT) including head-up tilt test can increase the diagnostic yield. However, up to one fifth of examined patients have inconclusive CAT results. The aim of the
