    Abstract : Mass spectroscopy imaging (MSI) has become a vital tool in modern research due to its ability to visualize the spatial distribution of molecules within tissue samples. The collaboration between researchers at AZ, the University of Gothenburg, and Chalmers University of Technology using the NanoSIMS instrument and MSI-SIMS technology has opened up new avenues of exploration in pharmaceutical development, particularly in examining drugs and metabolites at sub-cellular levels.

  3. 2. Multi-Label Toxic Comment Classification Using Machine Learning: An In-Depth Study

    University essay from Lunds universitet/Institutionen för datavetenskap

    Author : Matilda Froste; Mosa Hosseini; [2023]
    Keywords : natural language processing; machine learning; offensive speech detection; transformers; multi-label classification; Technology and Engineering;

    Abstract : The classification of toxic comments is a well-researched area with many techniques available. However, effectively managing multi-label categorization still requires a considerable amount of work. READ MORE

  4. 3. GO BACK TO /R/CONSPIRACY: AN EXPLORATION OF METHODS FOR THE AUTOMATIC DETECTION OF AFFECTIVE POLARIZATION ON REDDIT

    University essay from Göteborgs universitet / Institutionen för filosofi, lingvistik och vetenskapsteori

    Author : Klara Båstedt; [2022-10-06]
    Keywords : affective polarization; covid-19; social media; Reddit; NLP;

    Abstract : Affective polarization – the tendency to hold negative attitudes towards an out-group and biased, positive attitudes towards an in-group – is a hot topic in research and public debate. There are concerns that news media’s tendency to focus on political conflict rather than issues is causing polarization to increase, but researchers lack methods to automatically asses levels of polarization in online debates and correlate them with news articles.

  5. 4. Evaluating the robustness of DistilBERT to data shift in toxicity detection

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Caroline Larsen; [2022]
    Keywords : Machine learning; Natural Language Processing; DistilBERT; Toxicity Detection; Profanity Detection; Hate Speech Identification; Text preprocessing; Maskininlärning; naturligtspråkbehandling; DistilBERT; identifiering av kränkande språk; identifiering av svordomar; textbehandling;

    Abstract : With the rise of social media, cyberbullying and online spread of hate have become serious problems with devastating consequences. Mentimeter is an interactive presentation tool enabling the presentation audience to participate by typing their own answers to questions asked by the presenter. READ MORE

  6. 5. Analysis of polyfunctional thiols in beer : Developing a novel method of extraction and analysis using GC-FID

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Arvid Lindmark; [2022]
    Keywords : Beer; Hops; Thiols; 3MHA; 4MMP; Food Technology; Agriculture and Food Sciences;

    Abstract : In this project, attempts were made to identify and quantify two polyfunctional thiols – 4-mercapto-4-methyl-pentanone and 3-mercaptohexyl acetate – and three monoterpene alcohols – linalool, geraniol, and β-citronellol – in beer samples. In order to avoid the use of hazardous compounds such as dichloromethane and hydroxymercuriobenzoate, common in traditional methods, two novel techniques were tested: a pure liquid-liquid extraction of the beer samples with cyclohexane, and a liquid-liquid extraction with cyclohexane followed by solid phase extraction on silver ion columns.
