The bio-kinetic and sedimentation processes of wastewater treatment plants can be modelled by a large system of coupled nonlinear ordinary and partial differential equations (ODEs and PDEs). The subprocess of continuous sedimentation, which contains concentration discontinuities, is modelled by a degenerate parabolic conservation PDE with spatially discontinuous coefficients. A spatial discretizat

The gut microbiome of animals is emerging as an important factor influencing ecological and evolutionary processes. A major bottleneck in obtaining microbiome data from large numbers of samples is the time-consuming laboratory procedures required, specifically the isolation of DNA and generation of amplicon libraries. Recently, direct PCR kits have been developed that circumvent conventional DNA e

It has long been recognized that one of the fundamental difficulties in the estimation of two-view epipolar geometry is the capability of handling outliers. In this paper, we develop a fast and tractable algorithm that maximizes the number of inliers under the assumption of a purely translating camera. Compared to classical random sampling methods, our approach is guaranteed to compute the optimal

Purpose: Volumetry of cerebral ventricles is a far more sensitive measure for shunt-induced reduction of ventricular size than traditional 2-dimensional (2D) measures, such as Evans index. However, available ventricle segmentation methods are time-consuming, resulting in limited use in clinical practice. Quantitative MRI (qMRI) obtains objective measurements of physical tissue properties, enabling

Recombinant adeno-associated virus (rAAV) is a mammalian virus that has been altered to be used as a gene delivery vehicle. Several changes to the viral genome have made them replication deficient so that this aspect of the viral infection cycle is under full control of the experimenter, while maintaining gene expression machinery. Over the last decades, rAAVs have become the gold standard for stu

Accurate density matrix simulation of nuclear spin systems is critical for quantifying magnetic resonance spectroscopy (MRS) data, as well as for simulation studies designed to optimize acquisition parameters. Although a variety of packages exist to achieve this result, no currently available software is capable of computing a large number of spatial points in a reasonable time frame. Here we pres

We have a mix of students from all around the world. The tourism industry is experiencing major changes and challenges. Committed individuals, who can devel

Any ultrafast optical spectroscopy experiment is usually accompanied by the necessary routine of ultrashort-pulse characterization. The majority of pulse characterization approaches solve either a one-dimensional (e.g., via interferometry) or a two-dimensional (e.g., via frequency-resolved measurements) problem. Solution of the two-dimensional pulse-retrieval problem is generally more consistent d

Integration of high throughput data with online data resources is critical for data analysis and hypothesis generation. Relational databases facilitate the data integration, but larger amounts of data and the growth of the online data resources can slow down the data analysis process. We have developed a proof-of-principle software tool using concepts from the business intelligence field to enable

For the dosimetry of interstitial photodynamic therapy (IPDT), the fibre positioning and the distributed light fluence that activates the treatment are essential. With sufficient supply of oxygen and photosensitiser, the treatment effect depends entirely on the distributed light. By proper dosimetry, the illumination is limited to the tumour and adjacent sensitive tissues are spared. The fibre po

Popular Abstract in Swedish För att kunna mäta ett ämnes halt i ett prov behövs en analysmetod. Det första steget i en analysmetod innefattar provupparbetning. Med det menas att ämnet man vill mäta halten av avskiljs (extraheras) från provet med någon sorts extraktionsteknik. I laboratorier världen över görs dagligen många analytiska extraktioner. Det kan handla om t.ex. livsmedelsanalyser, miljöa

Carbon sequestration is an essential ecosystem service (ES) for climate change mitigation. For reasons of simplicity this ES is often quantified considering carbon storage in four carbon pools: aboveground biomass, belowground biomass, dead organic matter and soil organic carbon. Indicators of these four pools are estimated by modelling, reference values, or field methods and data processing of di
