PURPOSE: To propose and assess an improved method for calculating the equilibrium magnetization of arterial blood ( M0a), used for calibration of perfusion estimates in arterial spin labeling.METHODS: Whereas standard M0a calculation is based on dividing a proton density-weighted image by an average brain-blood partition coefficient, the proposed method exploits partial-volume data to adjust this
We have used femtosecond resolution UV-visible and Kβ x-ray emission spectroscopy to characterize the electronic excited state dynamics of [Fe(bpy)2(CN)2], where bpy=2,20-bipyridine, initiated by metal-to-ligand charge transfer (MLCT) excitation. The excited-state absorption in the transient UV-visible spectra, associated with the 2,20-bipyridine radical anion, provides a robust marker for the MLC

Quantum annealing is a promising approach for obtaining good approximate solutions to difficult optimization problems. Folding a protein sequence into its minimum-energy structure represents such a problem. For testing new algorithms and technologies for this task, the minimal lattice-based [hydrophobic (H) or polar (P) beads] HP model is well suited, as it represents a considerable challenge desp
Fundamental relations between information and energy – Building electronic devices that use information as fuel Scanning electron micrograph of a quantum dot structure where the movement of single electrons can be controlled and detected. The movement of a single electron in the structure yields the elemental amount of energy of kT ln(2) related to a single bit of information at temperature T. Fig

The position generator is a widespread method for measuring latent social capital in which respondents are queried about contacts on a list of occupations predefined by the analyst. We separate out the unique contribution of each occupation to aggregated measures of social capital. It turns out that this contribution varies vastly: knowing a person in some occupations provides substance to measure
With near stagnant growth in most mature car markets, much of the attention of the world´s car industry has during recent years turned to China. The Chinese car market represents an important business opportunity for OEMs and dealers who want to keep growing and making profits. Initially, the focus of OEMs was mainly on setting up new dealerships, often giving processes and technology lower priori
BackgroundA concussion is a common injury in many sports, including para sport. Aside from a more comprehensive need for concussion education, clinicians face difficulties applying concussion assessment and management guidelines to para athletes.1 At present, there is a lack of para-sport concussion research, and prior International Concussion in Sport (CIS) consensus papers have not addressed thi
The semiconductor industry is pivotal to Europe's economy, especially within the industrial and automotive sectors. However, Europe faces a significant shortfall in chip design capabilities, marked by a severe skilled labor shortage and lagging contributions in the design value chain segment. This paper explores the role of European universities and academic initiatives in enhancing chip design ed
The magnitude of variation in the gaze position signals recorded by an eye tracker, also known as its precision, is an important aspect of an eye tracker’s data quality. However, data quality of eye-tracking signals is still poorly understood. In this paper, we therefore investigate the following: (1) How do the various available measures characterizing eye-tracking data during fixation relate to
Swedish society is characterized by secularization, and at the same time, as a result of migration, the country has become more pluralistic. An important consequence of this is the increasing possibilities for cooperation between different religious communities, and a variety of inter-religious cooperation are currently taking place in Sweden. The aim of the article is to show how inter-religious
Popular Abstract in Swedish Kvantprickar är objekt där elektroner är instängda i en mycket liten volym (av storleksordningen 100 nanometer i varje riktning). I den här avhandlingen har vi studerat kvantprickar definierade i nanotrådar av halvledarmaterial. Nanotrådarna kan vara flera mikrometer långa men samtidigt mycket tunna (mindre än 100 nanometer eller 0,1 mikrometer). Vi har skapat kvantpriThis thesis focuses on electrical transport in semiconductor InAs nanowires grown by chemical beam epitaxy. Initially, transport length scales of homogeneous InAs n-type nanowires are characterized by low-temperature magnetoconductance measurements. The measurements show phase-coherent conductivity corrections. By fitting the data, we find the nanowire mean-free path to be 50 nm and the phase-cohe
Classical and quantum mechanics describe particle interactions fundamentally differently, yet isolated many-body systems generally thermalise in both descriptions. Recent studies using quantum simulators have observed exceptions to this, where the memory of special initial states is retained through anomalously long-lived revivals. The non-ergodic findings could be explained by Quantum Many-Body S
We present μ-PL and k·p calculations of self-assembled InP quantum dots (QDs) in GaInP. The QDs come in two subsets; the larger are pyramid shaped, and about 15 nm high with a base of about 40 by 50 nm, and the smaller have similar lateral extension but with a considerably lesser height. The change in size is accompanied by a change in quantum confinement and thus a change in emission energy. More
In addition to an increase in mean temperature, extreme climatic events, such as heat waves, are predicted to increase in frequency and intensity with climate change, which are likely to affect organism interactions, seasonal succession, and resting stage recruitment patterns in terrestrial as well as in aquatic ecosystems. For example, freshwater zooplankton with different life-history strategies
