1. A temporal Hawkes process model for shooting occurrences in Sweden
University essay from Lunds universitet/Statistiska institutionenAbstract : The Hawkes process, also referred to as a self-exciting point process, is a class of point processes where the intensity is conditioned on previous events. More specifically, an event occurrence excites the process, temporarily increasing the probability of more events occurring. READ MORE

2. Prospects for a Free Electron Laser at the FemtoMAX Beamline
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

3. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

4. Optogenetic and multiplexed gene editing in primary T-cells.
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Current T-cell tracking techniques in vivo are limited. The ability to successfully target a gene in vivo in T-cells and track movement throughout its life cycle provides an exciting opportunity to elucidate the functions of genes. READ MORE

5. Hawkes Processes on Socialand Mass Media: : A Causal Study of the #BlackLivesMatter Movement inthe Summer of 2020
University essay from Uppsala universitet/Statistik, AI och data scienceAbstract : In this work we study interactions in social media and the reports in mass media during the Black LivesMatter (BLM) protests following the death of George Floyd. We implement open-source pipelines to process the data at scale and employ the self-exciting counting process known as Hawkes process to address our main question: is there a causal relation between interactions in social media and reports of street protests in mass media? Specifically, we use distributed label propagation to identify such interactions in Twitter, that supported the BLM movement, and compared the timing of these interaction to those of news reports of street protests mentioning George Floyd, via the Global Database of Events, Language, and Tone (GDELT) Project.
