1. 1. Brain morphometry in Parkinson’s disease

   University essay from

   Author : Lönkvist Olivia; [2023-03-02]
   Keywords : Medical physics; Parkinson’s disease; Computational anatomy; Quantitative image analysis;

   Abstract : Abstract Purpose The purpose of this brain morphometry study was to examine the volumes of different regions of the brain by research participants with Parkinson’s disease. Method To carry out the study, MR (magnetic resonance) images from 956 research participants from the Parkinson’s Progression Markers Initiative (PPMI) were used. READ MORE

3. 2. Defining dark jets at the particle level

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Gustav Lindberg; [2023]
   Keywords : Particle physics; Dark matter; QCD; Physics and Astronomy;

   Abstract : One hypothesis that attempts to explain dark matter is dark QCD, which suggests that there would be a dark sector made up of dark quarks. Dark quarks would interact with each other through dark QCD similar to how Standard Model quarks interact with each other through Standard Model QCD. READ MORE

4. 3. Trigger-Level Multiple Electron Event Classification with LDMX using Artificial Neural Networks

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Jacob Lindahl; [2023]
   Keywords : LDMX; ANN; CNN; GNN; RNN; DM; Physics and Astronomy;

   Abstract : Artificial neural networks is a powerful tool for classifying and identifying patterns in large amounts of data. One of the possible tasks of these networks is classification of data into categories. READ MORE

5. 4. Neutrino Hotspots in the Universe: a Sensitivity Study Using the IceCube Neutrino Observatory

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Kiana Ghiassi; Julia Salwén; [2023]
   Keywords : Astrophysics; Neutrino Astronomy; Particle Physics; Neutrinos; Blazars; Sensitivity Study; IceCube Neutrino Obesvatory;

   Abstract : In this report, we aim to assess the sensitivity and 5$\sigma$ discovery potential of IceCube, the largest neutrino observatory on Earth, and compare it with prior findings. Our thesis will focus on a point source analysis, exploring the energy and declination dependencies, with particular emphasis on high-energy neutrinos. READ MORE

6. 5. Towards algorithmic theory construction in physics

   University essay from Stockholms universitet/Fysikum

   Author : Hampus Möller; [2023]
   Keywords : Symbolic regression; machine learning; symmetry; minimum description length; entropy;

   Abstract : This master thesis explores the challenge of algorithmic hypothesis generation and its connection to potential inductive biases. In the scientific method, hypotheses are formulated and tested against data for validity. The process of hypothesis generation is, however, not explicitly formulated. READ MORE
