  1. 1. Assessment and evaluation of heterogeneity in data from immune infiltration spatial niches in lung cancer

    University essay from Lunds universitet/Matematisk statistik

    Author : Mahta Keivani Najafabadi; [2023]
    Keywords : Mathematics and Statistics;

    Abstract : 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).

  2. 2. Making Sense of Material Culture : A Sensory Approach to Bird-Shaped Vessels in Imperial Age Greece

    University essay from Stockholms universitet/Antikens kultur och samhällsliv

    Author : Lina Enevång Viklund; [2023]
    Keywords : bird-shaped vessels; glass unguentaria; ancient senses; archaeology of the senses; ancient lived experience;

    Abstract : The focus of this thesis is Roman bird-shaped glass vessels from the 1 st and 2 nd centuries AD. The vessels were containers for cosmetics and distinguished themselves from other types of unguentaria in that once they had been filled with cosmetic powder, the vessels were reheated and sealed shut by fire.

    Abstract : This thesis examines the risk profile of Electronically Traded Funds and the dependence of the ESG rating on risk. 527 ETFs with exposure globally were analyzed. Risk measures considered were Value-at-Risk and Expected Shortfall, while some other metrics of risk was used, such as the volatility, maximum drawdown, tail dependece, and copulas. READ MORE

  4. 4. Rising Heat, Rising Risk: The Effect of Greenhouse Gas Emissions on Downside Tail Risk

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Moritz Neuber; Fabrice Van Lancker; [2023]
    Keywords : Climate Risk; Downside Risk; GHG Emissions; Tail Risk; Sustainable Finance;

    Abstract : Regulatory and societal attention to environmental pollution is increasing, and greenhouse gas (GHG) emissions are becoming a potential risk factor for investors. This paper uses panel data from S\&P 500 firms between 2015 and 2022 to investigate the link between GHG emissions and downside tail risk. READ MORE

  5. 5. A high-order artificial viscosity finite element method for the Vlasov-Poisson system

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Junjie Wen; [2023]
    Keywords : ;

    Abstract : 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
