This study investigates how changes in temperature affect the secondary organic aerosol (SOA) phase state. SOA was formed by α-pinene ozonolysis in an atmospheric simulation chamber at temperatures (T0) in the range of 257–283 K at RH0< 20%. After more than 14 h of SOA aging, one or more heating and cooling ramps were performed. Upon heating, we observe that the onset of evaporative SOA shrinkage
Sparse tensor computations suffer from irregular memory access patterns that degrade cache performance. While software prefetching can mitigate this, existing compiler approaches lack the semantic insight needed for effective optimization. We present ASaP, an automatic software prefetching framework integrated within MLIR’s sparse tensor dialect. By leveraging semantic information-tensor formats a
Passive seismic data were acquired together with active seismic data along a 2.8 km long profile in the Sudret area of Gotland, Sweden, as part of a feasibility study for storage of CO2 below the Baltic Sea. Seismic interferometry using cross-correlation and cross-coherence was employed on the passive seismic data. Cross-correlation was used to retrieve virtual shot gathers containing mainly surfa
How travellers perceive the quality of public transport services has profound influence on their satisfaction and thus of their inclination to choose this mode of transport. Punctuality, which may be interpreted as timetable adherence or overall travel time predictability, is often pointed out as the most important constituent of overall service reliability of public transport systems. However, in
This study examines the long-term socioeconomic impacts of 44 train station openings between 1995 and 2015 across Swedish regions. Using the conditional difference-in-differences estimator developed by Callaway and Sant'Anna (2021), which accounts for variation in treatment effects across time and locations, we evaluate the impact on population, income, education, and unemployment. Twenty years af
The railway transport system has seen an increasing demand in recent years, while delays and missed punctuality goals continue to be problems in many countries. To improve punctuality, the amount of primary delays needs to be decreased, and knowledge of the shares of the different types of delay – entry, run, and dwell – is important to identify the most efficient countermeasures. This paper inves
Phosphorene, a 2D allotrope of phosphorus, is technologically very appealing because of its semiconducting properties and narrow bandgap. Further reduction of the phosphorene dimensionality may spawn exotic properties of its electronic structure, including lateral quantum confinement and topological edge states. It is demonstrated that dispersions measured along and perpendicular to the phosphoren
This paper studies how cultural heritage influences the differences in risk taking in financial markets. We combine data on the asset allocation of second-generation immigrants in Sweden with risk taking culture in their parents’ countries of origin. We find that descendants of risk loving cultures are more likely to participate in equity markets, and, conditional on participation, allocate a larg
Computational analysis of large-scale metagenomics sequencing datasets provides valuable isolate-level taxonomic and functional insights from complex microbial communities. However, the ever-expanding ecosystem of metagenomics-specific methods and file formats makes designing scalable workflows and seamlessly exploring output data increasingly challenging. Although one-click bioinformatics pipelin
The aim of this study was to assess to what extent receptive vocabulary could be explained by morphological knowledge, language majority/minority background and socioeconomic status (SES) for Swedish 8–11-year-old children. A total of 89 children participated, of whom n = 47 were L1 speakers (language majority) and n = 42 were L2 speakers (language minority). Morphological knowledge (MK) was asses
Direct laser writing (DLW) has arise interest in a variety of fields due to the capabilities that we get from the realization of 2D and 3D structures with high resolution fabrication techniques. Multi-photon lithography (MPL) relies on non-linear absorption effects, making possible the fabrication of metasurfaces with feature size beyond the diffraction limit. A new approach in this direction is t
Streptococcus pyogenes, also known as group A Streptococcus (GAS), is a Gram-positive bacterial pathogen responsible for approximately 500,000 deaths globally per year. Therefore, surveillance of invasive GAS infections is of critical importance in understanding societal transmission. In this study, we propose an optical DNA mapping (ODM)-based assay for strain-level typing of S. pyogenes. Fluores
Background. Vaccine immunogenicity is reduced in kidney transplant recipients (KTRs), especially in those using mycophenolate mofetil (MMF). Whether replacement of MMF by everolimus improves vaccine immunogenicity is unknown. Methods. KTRs were randomized 1:1 to continue MMF or switch to everolimus. Participants received one coronavirus disease 2019 (COVID-19) booster vaccination and two herpes zo
