1. Assessment and evaluation of heterogeneity in data from immune infiltration spatial niches in lung cancer
University essay from Lunds universitet/Matematisk statistikAbstract : The protein biomarker expressions in three types of sampled immune INFILTration spatial niches in lung cancer tissue were measured using the new technology Digital Spatial Profiler (DSP). The three types of immune INFILTration that were observed in lung tumors were STROMA identified as immune cells separate from tumor cells, Tertiary lymphoid structures (TLS) identified as dense structures of organized immune cells and finally Infiltraterate where immune cells dispersed among and in direct contact with tumor cells (INFILT).

5. A high-order artificial viscosity finite element method for the Vlasov-Poisson system
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : We introduce a finite element method with high-order accuracy for approximating the Vlasov-Poisson system. This method uses continuous Lagrange polynomials as basis functions and employs explicit Runge-Kutta schemes for time discretization. A residual-based artificial viscosity technique is applied for stabilization. READ MORE
