Prosodic Disambiguation in Japanese: A Comparative Study of Native Speakers and Swedish L2 Learners

This thesis investigates whether intermediate and advanced Swedish learners of Japanese language can use prosodic cues—particularly pitch-based features such as downstep—to differentiate between structurally ambiguous noun phrases, specifically those having both left branching (LB) and right branching (RB) interpretations, in spoken Japanese in the same way as native speakers. It also examines

Towards Quantifying Veto Power with the LDMX HCal prototype

Vad kan stoppa oss från att hitta mörk materia med LDMX? När astronomer tittar på de största objekten i vårt universum ser de att stora strukturer, så som som galaxer och galaxkluster, inte rör sig som de förväntar sig. Det visar sig att det finnas en stor mängd extra materia som vi inte kan se. Denna osynliga materia kallar vi ’mörk materia’. Många teorier för vad mörk materia består av har lagtAccording to astronomical observations of galaxies and other large scale dynamics, the universe contains more mass than what is visible. This missing mass is called "dark matter" and have been a subject of study for physicists for decades. The Light Dark Matter eXperiment (LDMX) is a proposed experiment with the purpose to search for dark matter in a low mass range that not many experime

Neurophysiological Treatment Effects of Mesdopetam, Pimavanserin and Amantadine in a Rodent Model of Levodopa-Induced Dyskinesia

Levodopa provides effective symptomatic treatment for Parkinson's disease. However, nonmotor symptoms are often insufficiently relieved, and its long-term use is complicated by motor fluctuations and dyskinesia. To clarify mechanisms of levodopa-induced dyskinesia and pharmacological interventions aimed at reducing dyskinetic symptoms, we have here characterized the neurophysiological activity pat

Ice core dating with the 36Cl/10Be ratio

Extremely thinned layers and possible folding make the dating of the deepest sections of ice cores especially challenging. Cosmogenic radionuclides have the potential to provide independent age estimates. The 36Cl/10Be ratio is largely independent of production rate changes that affect individual radionuclides and has an effective half-life of 384 kyr, making it an ideal tool for dating the new 1.
