A reduced basis for option pricing
No full textWe introduce a reduced basis method for the efficient numerical solution of partial integro-differential equations which arise in option pricing theory. Our method uses a basis of functions constructed from a sequence of Black-Scholes solutions with different volatilities. We show that this choice of basis leads to a sparse representation of option pricing functions, yielding an approximation whose precision is exponential in the number of basis functions. A Galerkin method using this basis for solving the pricing PDE is presented. Numerical tests based on the CEV diffusion model and the Merton jump diffusion model show that the method has better numerical performance relative to commonly used finite-difference and finite-element methods. We also compare our method with a numerical Proper Orthogonal Decomposition (POD). Finally, we show that this approach may be used advantageously for the calibration of local volatility functions.

No full textQuality of life and personality traits in patients with malignant pleural mesothelioma and their first-degree caregivers

Taking into account the impact of MPM on emotional functioning and wellbeing, this study aimed to evaluate the quality of life and personality traits in patients with MPM and their first-degree caregivers through the World Health Organization Quality of Life–BREF (WHOQOL-BREF) and the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF). The sample was composed of 27 MPM patients, 55 first-degree relatives enrolled in Casale Monferrato and Monfalcone (Italy), and 40 healthy controls (HC). Patients and relatives reported poorer physical health than the HC. Patients had a higher overall sense of physical debilitation and poorer health than relatives and the HC, more numerous complaints of memory problems and difficulties in concentrating, and a greater belief that goals cannot be reached or problems solved, while often claiming that they were more indecisive and inefficacious than the HC. First-degree relatives reported lower opinions of others, a greater belief that goals cannot be reached or problems solved, support for the notion that they are indecisive and inefficacious, and were more likely to suffer from fear that significantly inhibited normal activities than were HC. In multinomial regression analyses, partial models indicated that sex, physical comorbidities, and the True Response Inconsistency (TRIN-r), Malaise (MLS), and Behavior-Restricting Fears (BRF) dimensions of the MMPI-2-RF had significant effects on group differences. In conclusion, health care providers should assess the ongoing adjustment and emotional wellbeing of people with MPM and their relatives, and provide support to reduce emotional distress.Keywords: asbestos, cancer, MMPI-2-RF, Casale Monferrato, Monfalcone, Ital
Hypertonic stress induces c-fos, but not c-jun expression in the human embrional EUE epithelial cell line
No full textRecent evidence has indicated a role for the two early response genes c-fos and c-jun in transcriptional regulation of genes acting in osmoregulation. On this basis we investigated their expression in response to hypertonic stress in the human embryonal EUE epithelial cell line. EUE cells have proven to be a useful tool for studying long-term in vitro adaptation to hypertonic stress. After culturing EUE cells in hypertonic medium a marked c-fos induction was observed, both at the mRNA and the protein level. Northern analysis of fos-mRNA showed a peak expression at 4 h, followed by a progressive decline till complete extinction at 8 h. Immunofluorescence analysis of FOS protein evidenced a similar, although slightly delayed kinetics of expression. Conversely, neither c-jun nor c-myc up-regulation could be detected. The treatment of EUE cells with cycloheximide led to superinduction of c-fos expression, (with high levels up to 12 h), and to a c-jun expression that was just detectable. Hypertonic stimulation of the transformed cell lines A549, MCF7 and JR induced both c-fos and c-jun only in JR cells. Hypertonic shock was also effective in inducing c-fos expression in fetal human diploid fibroblasts, although the response was earlier and more transient than in EUE cells. These findings indicate that c-fos is a primary response gene in hypertonic stress-activated cells, although the pattern and kinetics of its induction may differ according to the type of cell
