1. 6. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Isa Clementsson; [2023]
   Keywords : Physics and Astronomy;

   Abstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

3. 7. Psilocybin Induced Psychedelic Experiences : their Neural Mechanisms and Efficacy for Treating Depressive Disorders

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Linda Lindecrantz; Nicklas Villman; [2023]
   Keywords : psilocybin; depression; fMRI; systematic review; DMN;

   Abstract : The aim of this systematic review is to present the current literature on the therapeutic potential of the classic psychedelic compound psilocybin for depressive disorders and the neurocognitive mechanisms involved recorded with functional magnetic resonance imaging (fMRI). A comprehensive literature search was conducted in the electronic databases Web of Science, Scopus and Medline EBSCO using a Boolean search string containing the keywords psilocybin, depression, fMRI, MRI and PET.

4. 8. Multi-Agent Information Gathering Using Stackelberg Games

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

   Author : Yiming Hu; [2023]
   Keywords : Information gathering; Autonomous exploration; Multi-agent coordination; Multi-agent system; Informationsinsamling; Autonom utforskning; Samordning av flera agenter; multiagentsystem;

   Abstract : Multi-agent information gathering (MA-IG) enables autonomous robots to cooperatively collect information in an unfamiliar area. In some scenarios, the focus is on gathering the true mapping of a physical quantity such as temperature or magnetic field. READ MORE

5. 9. The neural correlates of cognitive reappraisal among post-traumatic stress disorder patients : A systematic review

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Cecilia Nordin; Cecilia Mattsson; [2023]
   Keywords : Emotion regulation; post-traumatic stress disorder; cognitive reappraisal; neural correlates; functional magnetic resonance imaging;

   Abstract : The ability to regulate emotions is essential for human well-being. Among posttraumatic stress disorder (PTSD) patients, the capability to control emotions is impaired. Trauma-focused cognitive behavioral therapy is a recommended treatment for patients diagnosed with PTSD. READ MORE

6. 10. Automatic Detection of Common Signal Quality Issues in MRI Data using Deep Neural Networks

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Erika Ax; Elin Djerf; [2023]
   Keywords : mr; magnetic resonance; machine learning; deep learning; anomaly detection; U-Net; autoencoder; 3D; classification; reconstruction; artefacts;

   Abstract : Magnetic resonance imaging (MRI) is a commonly used non-invasive imaging technique that provides high resolution images of soft tissue. One problem with MRI is that it is sensitive to signal quality issues. The issues can arise for various reasons, for example by metal located either inside or outside of the body. READ MORE
