Background: Over the last decade, computational sciences have contributed immensely to characterization of phenotypes of airway diseases, but it is difficult to compare derived phenotypes across studies, perhaps as a result of the different decisions that fed into these phenotyping exercises. We aim to perform a systematic review of studies using computational approaches to phenotype obstructive a
In post-quantum cryptography (PQC), Learning With Errors (LWE) is one of the dominant underlying mathematical problems. For example, in NIST's PQC standardization process, the Key Encapsulation Mechanism (KEM) protocol chosen for standardization was Kyber, an LWE-based scheme. The primal and the dual attacks are the two main strategies considered for solving the underlying LWE problem of multiple
The remodelling process in bones is closely related to electromechanical phenomena. In addition to streaming potentials and piezoelectricity, flexoelectricity has been found to serve as an initiator for remodelling in cortical bone. Since flexoelectricity is coupled to strain gradients, the effect is size-dependent and, accordingly, most relevant on small scales. This means that particularly micro
Qualitative and quantitative visualizations of transonic turbomachinery flows provide essential information on compressibility and Mach number effects on boundary layer development, shock-boundary layer interactions (SBLI) and trailing edge flows. Background Oriented Schlieren (BOS) is a relatively new optical technique that allows capturing unsteady density gradient fields through turbomachinery
PURPOSE: The aim of this study was to evaluate how relatives of patients with an ostomy rated the various aspects of care, how they perceived the quality of the care provided, and how they ranked their involvement in the care. Patients' satisfaction was also sought, particularly their perception of relatives' involvement.DESIGN: Descriptive cross-sectional.SETTINGS AND SUBJECTS: The study comprise
This paper investigates the confluence of artificial intelligence (AI), the performing arts, and emotion communication, focusing on how generative AI and social robotics – today’s forefront disruptive technologies – can facilitate an exploration of emotional dynamics across artistic mediums. Drawing on the intermedial and multimodal capacities of opera, this paper presents AI-enhanced opera as a p
The Hidden Conference is a film in three parts. Each projection investigates the storage facilities of a European museum, where artworks are kept while not on display. About the Discontinuous History of Things We See and Don’t See, projected in the first room, was filmed at the stores of the Neue Nationalgalerie in Berlin in 2010. About the Shelf and Mantel, shown in the following gallery, was sho
This thesis covers a set of methods related to machine perception and localization, which are two important building blocks of artificial intelligence. In Paper I, we explore the concept of regression via classification (RvC), which is often used for perception tasks where the target variable is either ordinal or when the distance metric of the target space is not well-suited as an objective funct
This work presents a data-driven method for learning low-dimensional time-dependent physics-based surrogate models whose predictions are endowed with uncertainty estimates. We use the operator inference approach to model reduction that poses the problem of learning low-dimensional model terms as a regression of state space data and corresponding time derivatives by minimizing the residual of reduc
The implementation of the Biofuels Directive (2003/30/EC) in the 25 member states is assessed against the background of implementation theory in this paper. The aim is to identify and analyze implementation problems for the purpose of suggesting a way forward for biofuels policy in the European Union. Three main patterns of policy implementation are observed: effective implementation, formal compl
Detailed information from the Swedish National Forest Inventory was used to simulate the carbon balance for Sweden by the process-based model Biome-BGC. A few shortcomings of the model were identified and solutions to those are proposed and also used in the simulations. The model was calibrated against CO2 flux data from 3 forests in central Sweden and then applied to the whole country divided int
We are living in a changing society where businesses need to keep themselves updated and adapt to changing circumstances. Hence, some brands need to repo- sition themselves to survive. The purpose with repositioning is that a brand wants to convey a different identity and therefore create a new image and position in the consumer’s mind. However, one can only control the change of the identity sinc
Abstract in Undetermined A classical solution for matching two image patches is to use the cross-correlation coefficient. This works well if there is a lot of structure within the patches, but not so well if the patches are close to uniform. This means that some patches are matched with more confidence than others. By estimating this uncertainty, more weight can be put on the confident matches thaA classical solution for matching two image patches is to use the cross-correlation coefficient.

Oat-based beverages enriched with vitamins and minerals were produced with common hydrothermal treatments and stored at 22 degrees C for 64 weeks. The effects of decanting on the retention of native vitamins, minerals and fatty acids, and different UHT holding time (5 s or 20 s) at 140 degrees C on vitamins were investigated. Fatty acid profile, vitamin retention and dissolved oxygen concentration
Von Economo neurons (VEN) are bipolar neurons located in the anterior cingulate cortex (ACC) and the frontoinsular cortex (FI), areas affected early in behavioural variant frontotemporal dementia (bvFTD), in which VEN may constitute a selectively vulnerable cellular population. Aim A previous study has shown a selective loss of VEN in FTD above other neurons in the ACC of FTD. The aim of this stud
Dermatan sulfate (DS) chains are variants of chondroitin sulfate (CS) that are expressed in mammalian extracellular matrices and are particularly prevalent in skin. DS has been implicated in varied biological processes including wound repair, infection, cardiovascular disease, tumorigenesis, and fibrosis. The biological activities of DS have been attributed to its high content of IdoA(alpha 1-3)Ga
The coronary arteries of the isolated rabbit heart were perfused with different contrast media (CM). The effects on cardiac contractile force (CF) from enriching iohexol solutions with sodium, calcium, potassium, magnesium and oxygen were investigated. The effects were studied during normal and reduced perfusion pressure; the latter was intended to simulate flow conditions distal to proximal steno
