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...

Alternatives to Traditional Per-Oral Endoscopy for Screening.
Barrett's esophagus (BE) predisposes patients to esophageal adenocarcinoma. 3 to 6% of individuals with gastro-esophageal reflux disease are estimated to have BE but only 20 to 25% of BE patients are currently diagnosed. The...
Body mass index and body composition in relation to 14 cardiovascular conditions in UK Biobank
AIMS: The causal role of adiposity for several cardiovascular diseases (CVDs) is unclear. Our primary aim was to apply the Mendelian randomization design to investigate the associations of body mass index (BMI) with 13 CVDs and...

Delicate seafloor landforms reveal past Antarctic grounding-line retreat of kilometers per year.
JA Dowdeswell, CL Batchelor, A Montelli, D Ottesen, FDW Christie, EK Dowdeswell, J Evans
Jun 04, 2020
A suite of grounding-line landforms on the Antarctic seafloor, imaged at submeter horizontal resolution from an autonomous underwater vehicle, enables calculation of ice sheet retreat rates from a complex of grounding-zone...
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...
Associating the Change in New COVID-19 Cases to GDP per Capita in 38 European Countries in the First Wave of the Pandemic.
COVID-19 has affected all countries globally. We explore associations between the change in new COVID-19 registered cases per million population and various macroeconomic and well-being indicators in 38 European countries over a...
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...
The Municipality's Role in a Smart Internet of Things Ecosystem
This article explores how municipalities plan and utilize Internet of Things (IoT) for smart city development, as well as how they collaborate with actors in the IoT-ecosystem. To do so, in-depth interviews and secondary...

Organomegaly in Mali before and after praziquantel treatment. A possible association with Schistosoma haematobium.
Chalotte Willemann Stecher, Henry Madsen, Shona Wilson, Moussa Sacko, Christian Wejse, Adama D Keita, Aly Landouré, Mamadou S Traoré, Per Kallestrup, Eskild Petersen, Birgitte Vennervald
Jan 24, 2018
Continuous exposure to schistosome-infested water results in acute and chronic morbidity in all ages. We analysed occurence of organomegaly via ultrasonography and investigated a possible additive effect of dual-dose drug...
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...
Intelligent Anti-Jamming Decision Algorithm of Bivariate Frequency Hopping Pattern Based on DQN With PER and Pareto
To improve the anti-jamming performance of frequency hopping system in complex electromagnetic environment, a Deep Q-Network algorithm with priority experience replay (PER) based on Pareto samples (PPER-DQN) is proposed, which...
