The aim of this thesis is to find an efficient simulation method of the Heston model of stochastic volatility to price path dependent derivatives. The volatility process in this model has an exact transition density defined as a scaled non central chi2 density. By implementing classic approaches of approximating the non central chi2 distribution, and modifying Andersen's Quadratic Exponential
Popular Abstract in Swedish Monoaminer Adrenalin, noradrenalin, dopamine, serotonin och histamin är samtliga monoaminer som fungerar som signalsubstanser och hormoner. Monoaminer är viktiga i många fysiologiska processer och obalans i deras nivåer ger ett brett spektrum av störningar. De klassiska är: serotoninbrist som ger depression, ångest och sömnstörningar, dopaminbrist ger motoriska störninThe present study explored the gene and protein expression of the monoamine transporters in human endometrium throughout the menstrual cycle, in early decidua and in placentas from normal as well as preeclamptic pregnancies using in-situ hybridization, real time-PCR, immunohistochemistry and primary tissue cultures. Four distinguishable patterns were observed in the endometrium over the menstrual
Multivariate random sums appear in many scientific fields, most notably in actuarial science, where they model both the number of claims and their sizes. Unfortunately, they pose severe inferential problems. For example, their density function is analytically intractable, in the general case, thus preventing likelihood inference. In this paper, we address the problem by the method of moments, unde

Crude oil is the most traded energy commodity in the world, and its price has a large impact on the everyday life of billions. Given the volatility of crude oil prices and its enormous effects on economies worldwide, there has been a growing demand for risk quantification and risk management for the market participants. The measurement known as Value-at-Risk (VaR) has become the industry standard
This thesis aims to understand copula theory and its application in measuring dependence, particularly in the context of the paper "Multivariate conditional versions of Spearman’s rho and related measures of tail dependence" by Schmid and Schmidt. We clarify certain statements and formulas in Schmid and Schmidt's work, explore the potential of the conditional version of Spearman'
Popular Abstract in Swedish Denna avhandling är en sammanläggningsavhandling och består av åtta delarbeten. Delarbetena är publicerade i internationella vetenskapliga tidskrifter, utom delarbete VI-VIII som är föremål för granskning i sådana tidsskrifter inför möjlig publikation. Alla delarbeten representerar studier av bisköldkörteln. Bisköldkörtlarna (parathyroidea) är belägna i anslutning tillThe occurrence and distribution of neurohormonal peptides, neuroendocrine markers and receptors in parathyroid nerve fibers and endocrine cells are described, using immunocytochemistry, in situ hybridization, image analysis and reverse transcriptase polymerase chain reaction. Immunocytochemical studies revealed that parathyroid glands of chicken, rat, guinea-pig, cat, dog and sheep contained adren
Surgery for Hirschsprung's disease is often complicated by post-operative bowel motility disorders. The impact of intestinal neural histology on the surgical outcome has been previously studied, but no information is available concerning the influence of the distribution of interstitial cells of Cajal (ICC) on these complications. These cells are considered to be pacemakers in the gastrointestinal
Popular Abstract in Swedish Konstant produktion av blodceller i benmärgen krävs för att bibehålla normal syretransport i blodet, sårläkning och ett effektivt immunförsvar. Bakom denna produktion ligger hematopoetiska blodstamceller som regleras av en komplex interaktion mellan dem och deras omgivning. Varje blodstamcell kan med självförnyande celldelningar, där minst en dottercell bibehåller en stHematopoietic stem cells (HSC) are sufficient and required for life long production of all blood cell lineages. Steady state HSCs are largely quiescent and we demonstrate that the kinetics of HSC cell cycling are slower compared to more committed progenitor cells also during expansion and self-renewal ex vivo and in physiological conditions. Such slow kinetics during cell division might reflect a
Perimetric probability maps depict visual field results in terms of the frequency with which the measured findings are seen in a normal population. We tested clinically the importance of the model of the normal visual field used to calculate such maps. Forty-one eyes of 41 normal subjects and 58 eyes of 46 glaucomatous patients were studied. Probability maps were calculated by means of two differe
We introduce a family of boundary confinements for Coulomb gas ensembles, and study them in the two-dimensional determinantal case of random normal matrices. The family interpolates between the free boundary and hard edge cases, which have been well studied in various random matrix theories. The confinement can also be relaxed beyond the free boundary to produce ensembles with fuzzier boundaries,
