- When combined with the huge collecting area of the ELT, MOSAIC will be the most effective and flexible Multi-Object Spectrograph (MOS) facility in the world, having both a high multiplex and a multi-Integral Field Unit (Multi-IFU) capability. It will be the fastest way to spectroscopically follow-up the faintest sources, probing the reionisation epoch, as well as evaluating the evolution of the dwarf mass function over most of the age of the Universe. MOSAIC will be world-leading in generating an inventory of both the dark matter (from realistic rotation curves with MOAO fed NIR IFUs) and the cool to warm-hot gas phases in z=3.5 galactic haloes (with visible wavelenth IFUs). Galactic archaeology and the first massive black holes are additional targets for which MOSAIC will also be revolutionary. MOAO and accurate sky subtraction with fibres have now been demonstrated on sky, removing all low Technical Readiness Level (TRL) items from the instrument. A prompt implementation of MOSAIC is feasible, and indeed could increase the robustness and reduce risk on the ELT, since it does not require diffraction limited adaptive optics performance. Science programmes and survey strategies are currently being investigated by the Consortium, which is also hoping to welcome a few new partners in the next two years.

Investigating the Effects of MWE Identification in Structural Topic Modelling
- 2023
-
Ingår i: 19th Workshop on Multiword Expressions, MWE 2023 - Proceedings. - : ACL. ; , s. 36-44
-
Konferensbidrag (refereegranskat)abstract
- Multiword expressions (MWEs) are common word combinations which exhibit idiosyncrasies in various linguistic levels. For various downstream natural language processing applications and tasks, the identification and discovery of MWEs has been proven to be potentially practical and useful, but still challenging to codify. In this paper we investigate various, relevant to MWE, resources and tools for Swedish, and, within a specific application scenario, we apply structural topic modelling to investigate whether there are any interpretative advantages of identifying MWEs.

Scaling-up the Resources for a Freely Available Swedish VADER (svVADER)
- 2023
-
Ingår i: Proceedings of the 24th Nordic Conference on Computational Linguistics (NoDaLiDa).

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- With widespread commercial applications in various domains, sentiment analysis has become a success story for Natural Language Processing (NLP). Still, although sentiment analysis has rapidly progressed during the last years, mainly due to the application of modern AI technologies, many approaches apply knowledge-based strategies, such as lexicon-based, to the task. This is particularly true for analyzing short social media content, e.g., tweets. Moreover, lexicon-based sentiment analysis approaches are usually preferred over learning-based methods when training data is unavailable or insufficient. Therefore, our main goal is to scale-up and apply a lexicon-based approach which can be used as a baseline to Swedish sentiment analysis. All scaled-up resources are made available, while the performance of this enhanced tool is evaluated on two short datasets, achieving adequate results.

Circle to circle amplification for detection of antibiotic resistance genes
- 2022
-
Ingår i: Uppsala Antibiotic Days: a multidisciplinary conference. ; , s. 37-
-
Konferensbidrag (refereegranskat)abstract
- Detection of antibiotic resistance is paramount for accurate and effective treatment of infectious bacterial diseases. There is a growing interest for methods making it possible to identify the specific genes giving rise to antibiotic resistance. Molecular detection approaches have evolved to the point where many techniques can be performed in clinics, bedside setups or implemented in microfluidic chips as they require little equipment and training. Rolling circle amplification (RCA) is an isothermal DNA amplification technique that amplifies synthetic circular DNA probes that have been hybridized to a complementary target present in the sample. To increase the number of amplification products, several rounds of RCA may be performed on a single sample. This technique is denoted as circle-to-circle amplification (C2CA).
