In diffusion MRI (dMRI), images are sensitised to water diffusion by the application of magnetic field gradients. Cell membranes hinder the diffusional motion and thereby contribute to the contrast in dMRI. Thus, the diffusion of water molecules is used a probe of tissue microstructure. Data from dMRI is often analysed using diffusion tensor imaging (DTI), which yields image biomarkers that reflecIn diffusion MRI (dMRI), images are sensitised to water diffusion by the application of magnetic field gradients.

För att förbli konkurrenskraftiga i en globaliserad värld försöker multinationella bolag ständigt att hitta nya sätt för att öka deras vinst. Ett viktigt område i detta hänseende, som kan ha en betydande inverkan på bolagens totala resultat, är strukturen av bolagen i den multinationella koncernen. Genom att välja rätt struktur kan koncernen uppnå skattemässiga fördelar genom att vinster kan flyttTo remain competitive in the globalized economy, multinationals are consistently searching for new ways to increase their overall profit. An important aspect of this goal is the structure of the companies within the multinational group. By selecting the proper business structure, the group can gain tax advantages derived from profits shifting from high tax jurisdictions to a low tax jurisdiction.

Uppsatsen pekar på att många operatörer på den svenska marknaden inte har lyckats helt med sina strategier. Orsakerna till detta kan vara brister i såväl marknadsföring som förståelse för konsumenternas behov. Lågprisstrategier måste för att lyckas kombineras med aggressiv marknadsföring och.

Various scaffolds, natural or artificial, have been used for neural repair, including basal lamina scaffolds obtained through extraction of nerves. Here we tested whether plastic casts of such preparations could be used for neurite guidance. To this end, longitudinal micron thick sections of rat sciatic nerve were extracted with detergents and treated with Dnase, yielding an acellular basal lamina

A number of minimal problems of structure from motion for cameras with radial distortion have recently been studied and solved in some cases. These problems are known to be numerically very challenging and in several cases there exist no known practical algorithm yielding solutions in floating point arithmetic. We make some crucial observations concerning the floating point implementation of Gröbn

These problems are known to be numerically very challenging and in several cases there were no practical algorithms yielding solutions in floating point arithmetic. We make some crucial observations concerning the floating point implementation of Gröbner bas

As multimedia- and group-oriented computing becomes increasingly popular for the users of wireless mobile networks, the importance of features like quality of service (QoS) and multicasting support grows. Ad hoc networks can provide users with the mobility they demand, if efficient QoS multicasting strategies are developed. The ad hoc QoS multicasting (AQM) protocol achieves multicasting efficienc

The Middle East in the Contemporary World (MECW) is a multi- and transdisciplinary strategic research area, hosted and supported by the Center for Middle Eastern Studies, comprising staff from five different faculties at Lund University.

We present an approach for connecting and coordinating distributed devices with different capabilities. More specifically, our research focuses on the design of an domain specific language that allows end-users to coordinate devices in pervasive systems.

This paper addresses design space exploration for streaming applications (such as MPEG) running on multi-processor platforms with guaranteed service interconnects. In particular, we solve mapping, path selection and router configuration problems. Given the complexity of these problems, state of the art approaches in this area largely rely on greedy heuristics, which do not guarantee optimality. Ou

Background: Tumor immune cell infiltration is a favorable prognostic factor in triple-negative breast cancer. Most triple-negative tumors belong to the aggressive basal-like subtype. We hypothesized that immune gene expression may identify low-risk patients for whom adjuvant chemotherapy can be de-escalated. Methods: The expression of 753 immune-related genes was analyzed in tumor biopsies from 45

Previously it demonstrated that in the absence of Ca2+ entry, evoked secretion occurs neither by membrane depolarization, induction of [Ca2+]i rise, nor by both combined (Ashery, U., Weiss, C., Sela, D., Spira, M. E., and Atlas, D. (1993). Receptors Channels 1:217-220.). These studies designate Ca2+ entry as opposed to [Ca2+]i rise, essential for exocytosis. It led us to propose that the channel a

Object: A method is proposed that provides spectroscopic images with high spatial resolution and moderate spectral resolution at very short total data acquisition times. Materials and methods: Balanced steady-state free precession (bSSFP, TrueFISP, FIESTA, b-FFE) is combined with a multiecho readout gradient and frequency-sensitive reconstruction such as Fourier reconstruction known from echo-plan

Protease-responsive multi-arm polyethylene glycol-based microparticles with biscysteine peptide crosslinkers (CGPGG↓LAGGC) were obtained for intradermal drug delivery through inverse suspension photopolymerization. The average size of the spherical hydrated microparticles was ∼40 μm after crosslinking, making them attractive as a skin depot and suitable for intradermal injections, as they are read

A new encapsulation strategy for probiotics is highly needed to tackle the challenge of significant viability loss of bacteria during storage and passage through the gastrointestinal system. A new controlled delivery system for probiotics based on EC oleogels is proposed in this thesis. A relatively non-complicated in vitro lipolysis model was established to evaluate the relative conversion from t

This study investigates the manufacturing and application of enteric polymeric microneedles loaded with active pharmaceutical ingredients and combined with photoresponsive dyes used for micromotor motion. The aim is to present an alternative method for orally delivering macromolecules. Although needle fear among patients has led to investigations into alternative routes of administration for macro

Background. The best mode of delivery in cases of intrauterine growth restriction (IUGR) with umbilical artery blood flow changes is not well elucidated. Objective. To evaluate outcome in IUGR with umbilical artery blood flow changes planned for vaginal delivery after a negative oxytocin challenge test (OCT). Methods. In 84 term singleton pregnancies with suspected IUGR and no unanimous indicati
