Purpose The purpose of this study was to estimate the uncertainty in voluntary deep-inspiration breath-hold (DIBH) radiotherapy for locally advanced non-small cell lung cancer (NSCLC) patients. Methods Perpendicular fluoroscopic movies were acquired in free breathing (FB) and DIBH during a course of visually guided DIBH radiotherapy of nine patients with NSCLC. Patients had liquid markers injected
A number of studies have analysed how multinational enterprises (MNEs) develop appropriate strategies for managing the institutionally different contexts of various markets. However, we still know rather little about how MNEs manage different institutional pressures when they operate in emerging markets. These markets have a higher level of uncertainty as their values and structures undergo change

Introduction: In allergic asthma patients, one of the more common phenotypes might benefit from allergen immunotherapy (AIT) as add-on intervention to pharmacological treatment. AIT is a treatment with disease-modifying modalities, the evidence for efficacy is based on controlled clinical trials following standardized endpoint measures. However, so far there is a lack of a consensus for asthma end
The objectives of this study were to analyse the changes in airway cross-sectional areas and volumes due to surgical movements of the jaws and to identify any possible correlation with the direction of the movements. Fifty-seven participants, aged 18–28 years (mean 20.8 years) at surgery, were followed up for 12 months postoperatively. Pre- and postoperative measurements of the facial region obtai
Abstracts, NS166: Emerging Quantum Technologies Heike Riel (overview talk): Computing – From Bits to Qubits Classical computers which represent information as bits have evolved over many years in an unprecedented way and became ubiquitous in our life. Today these classical technologies based on miniaturization are reaching their limits and new computing paradigms are in quest to reduce power consu

LuCuGaO4 has magnetic Cu2+ and diamagnetic Ga3+ ions distributed on a triangular bilayer and is suggested to undergo a spin glass transition at T-g similar to 0.4 K. Using mu SR (muon spin rotation) and neutron scattering measurements, we show that at low temperature the spins form a short range correlated state with spin fluctuations detectable over a wide range of timescales: at 0.05 K magnetic
Richter Group Our ResearchOsteoclasts and osteoblasts are two important mediators in the tightly regulated process of bone remodelling. The bone-forming osteoblasts are of mesenchymal origin while the multinucleate osteoclasts, which are responsible for bone resorption, are derived from hematopoietic stem cells (HSCs). An imbalance between the production and destruction of bone can lead to either

Popular Abstract in Swedish I min avhandling har jag tittat på möjligheten att göra om mänskliga hudceller direkt till dopaminerga nervceller. Dessa uppvisar flera egenskaper tillskrivna de dopaminerga nervceller vi hittar i hjärnan. Jag tittar även på möjligheten att transplantera dessa som hudceller i hjärnan på råttor och sen göra om dom till nervceller när de är på plats. Dessa celler bildar nCellular reprogramming is when one cell is changed into another. This involves structural modifications on the DNA of a cell resulting in a transcriptional change. This occurs naturally during development when early pluripotent cells gradually differentiate into more specialized cells that finally result in a complete organism. This is a finely orchestrated event that includes both extrinsic and i
Common reed is found in near-shore areas of many European lakes, where it forms dense stands. As waves are influenced by obstacles along the wave path, water and sediment motions caused by waves are affected by these stands. This study aims to evaluate the effect of common reed stands on waves, evaluate the effect of common reed stands on wave induced sediment resuspension, test a model for wave a
A mixed initial-boundary value problem for a nonlocal, hyperbolic equation is analyzed with respect to unique solubility and causality. The regularity of the step response and impulse response (the Green functions) is investigated, and a wave front theorem is proved. The problem arises, e.g., at time-varying, electromagnetic, plane wave excitation of stratified, temporally dispersive, bi-isotropic
A microfluidic strategy to perform buffer exchange of particle and cell suspensions in a continuous flow format on, chip is presented. Ultrasonic standing wave technology is utilized to confine particulate matter to the centre of a buffer exchange channel while particle free buffer is sequentially aspirated via capillaries that branch off from the buffer exchange channel. At each such branch, clea
Cell-free massive MIMO systems consist of many distributed access points with simple components that jointly serve the users. In millimeter wave bands, only a limited set of predetermined beams can be supported. In a network that consolidates these technologies, downlink analog beam selection stands as a challenging task for the network sum-rate maximization. Low-cost digital filters can improve t
