We evaluate two coordinate transformation techniques in combination with grid stretching for pricing basket options in a sparse grid setting. The sparse grid technique is a basic technique for solving a high-dimensional partial differential equation. By creating a small hypercube sub-grid in the ‘composite’ sparse grid we can also determine hedge parameters accurately. We evaluate these techniq...

Cholecystokinin (CCK) is an abundant neuropeptide involved in normal behaviour and pathophysiological conditions. Recently, CCK was shown to act as a molecular switch for perisomatic inhibition in the hippocampus, by directly depolarizing parvalbumin expressing (PV+) basket cells while indirectly depressing GABA release from CCK expressing (CCK+) basket cells. However, whether these two CCK-med...

For decades, humans have been consuming large quantities of oil, coal and natural gas. Consequently, people must now take responsibility for having participated in productive activities that have caused the emissions of greenhouse gas (GHG) which has damaged the environment and caused problems associated with abnormal weather. Previous studies investigated the relationships between energy and c...

Large scale use of groundwater for irrigation which is often Arsenic laden, during past two decades, has given rise to the apprehension that this may be resulting in higher Arsenic intake through the food chain. This work was undertaken to determine the trend of average Arsenic exposure of the population in Bangladesh during the period 1990-2010. Based on available data on individual food items...

Assumption of exchange rate overshooting has significant position in international macroeconomic discussion. This phenomenon is one of the abnormal behaviors of exchange rate that happen in short run. Dornbusch (1976) shows that because speed of equilibrium prices is slow relative to asset markets and commodity prices are sticky in the short run, However, over time, commodity prices will rise a...

Utilizing simulation approach, this paper examines if the income distribution inequality of a country expands through globalization and/or innovation, somewhat modifying the traditional Heckscher–Ohlin model. First, independently of innovation, the globalization is examined for a country A with two industries (commodities) and four consumers: the (aggregate) worker, the (aggregate) capitalist, ...
