Efficient Magnus-type integrators for solar energy conversion in Hubbard models
Winfried Auzinger, Juliette Dubois, Karsten Held, Harald Hofstätter, Tobias Jawecki, Anna Kauch, Othmar Koch, Karolina Kropielnicka, Pranav Singh, Clemens Watzenböck
Jan 31, 2022
Strongly interacting electrons in solids are generically described by Hubbardtype models, and the impact of solar light can be modeled by an additional time-dependence. This yields a finite dimensional system of ordinary...

Investigation of Reverse Swing and Magnus Effect on a Cricket Ball Using Particle Image Velocimetry
Lateral movement from the principal trajectory, or “swing”, can be generated on a cricket ball when its seam, which sits proud of the surface, is angled to the flow. The boundary layer on the two hemispheres divided by the seam...

Fast Nonparametric Clustering of Structured Time-Series.
In this publication, we combine two Bayesian nonparametric models: the Gaussian Process (GP) and the Dirichlet Process (DP). Our innovation in the GP model is to introduce a variation on the GP prior which enables us to model...
Hierarchical Bayesian modelling of gene expression time series across irregularly sampled replicates and clusters.
BACKGROUND: Time course data from microarrays and high-throughput sequencing experiments require simple, computationally efficient and powerful statistical models to extract meaningful biological signal, and for tasks such as...
Sixth-order schemes for laser-matter interaction in the Schrödinger equation
Pranav Singh
Apr 21, 2019
Control of quantum systems via lasers has numerous applications that require fast and accurate numerical solution of the Schrödinger equation. In this paper, we present three strategies for extending any sixth-order scheme...
Competing models of organizational form
Mutual and stock insurers have coexisted and competed against each other in insurance markets for centuries. In this article, we examine the risk management strategies and underwriting profitability of the different...
MOTMOT
The disparity in species’ traits arises through variation in the tempo and mode of evolution over time and between lineages. Understanding these patterns is a core goal in evolutionary biology. Here we present the...
Firm size and growth in Sweden's life insurance market between 1855 and 1947
Using data for the period from 1855 to 1947 and the two sub-periods, 1855-1902 and 1903-47, the article examines whether the organic growth rates of 38 Swedish life insurance firms are independent of size, as predicted by...

Managing policy lapse risk in Sweden's life insurance market between 1915 and 1947
Michael Adams, Lars Fredrik Andersson, Liselotte Eriksson, Magnus Lindmark, Elena Veprauskaite
Feb 17, 2020
We examine the challenges that Swedish life insurers faced in managing the lapse risk of policies written on the lives of the industrial urban working-class between 1915 and 1947. We observe that with the threat of State...
Body mass index and subfertility

STUDY QUESTION: What is the association between BMI and subfertility? SUMMARY ANSWER: We observed a J-shaped relationship between BMI and subfertility in both sexes, when using both a standard multivariable regression and...
Field interventions for climate change mitigation behaviors
Behavioral change is essential to mitigate climate change. To advance current knowledge, we synthesize research on interventions aiming to promote climate change mitigation behaviors in field settings. In a preregistered...
Plasma Phospholipid Fatty Acids, FADS1 and Risk of 15 Cardiovascular Diseases
Shuai Yuan, Magnus Bäck, Maria Bruzelius, Amy M. Mason, Stephen Burgess, Susanna Larsson
Dec 10, 2019
Whether circulating fatty acids (FAs) play a causal role in the development of cardiovascular disease (CVD) remains unclear. We conducted a Mendelian randomisation study to explore the associations between plasma phospholipid FA...
Genetic variation regulates the activation and specificity of Restriction-Modification systems in Neisseria gonorrhoeae
ABSTRACT Restriction-Modification systems (RMS) are one of the main mechanisms of defence against foreign DNA invasion and can have an important role in the regulation of gene expression. The obligate human pathogen Neisseria...

Removal of pharmaceuticals in pre-denitrifying MBBR – Influence of organic substrate availability in single- and three-stage configurations
Fabio Polesel, Elena Torresi, Luca Loreggian, Mònica Escolà Casas, Magnus Christensson, Kai Bester, Benedek Gy Plósz
Oct 15, 2017
Due to the limited efficiency of conventional biological treatment, innovative solutions are being explored to improve the removal of trace organic chemicals in wastewater. Controlling biomass exposure to growth substrate...
