Commensurate with this exponential growth in the depth and breadth of derivative markets and the range of financial products traded therein, there needs to be developed a comprehensive mathematical framework to support the, hitherto, empirically established features of trading strategies involving these instruments. It is the objective of this article, to provide a mathematical backup for the various properties of 'volatility trading' strategy using call options. Additionally, an attempt is made to elucidate the implications of behavior of various 'option Greeks' on volatility trading.

Growth kinetics of Thiobacillus ferrooxidans in batch cultures, containing prills of elementary sulfur as the sole energy source, were studied by measuring the incorporation of radioactive phosphorus in free and adsorbed bacteria. The data obtained indicate an initial exponential growth of the attached bacteria until saturation of the susceptible surface was reached, followed by a linear release of free bacteria due to successive replication of a constant number of adsorbed bacteria. These adsorbed bacteria could continue replication provided the colonized prills were transferred to fresh medium each time the stationary phase was reached. The bacteria released from the prills were unable to multiply, and in the medium employed they lost viability with a half-life of 3.5 days. The spreading of the progeny on the surface was followed by staining the bacteria on the prills with crystal violet; this spreading was not uniform but seemed to proceed through distortions present in the surfa...

Recent progress in genomics and experimental biology has brought exponential growth of the biological information available for computational analysis in public genomics databases. However, applying the potentially enormous scientific value of this information to the understanding of biological systems requires computing and data storage technology of an unprecedented scale. The grid, with its aggregated and distributed computational and storage infrastructure, offers an ideal platform for high-throughput bioinformatics analysis. ...

Objective: The objective of this paper is to analyse and quantify the effects exerted on summer mortality by extremes of heat, particularly among persons aged 65–74 and 75 years and over, groups in which mortality is higher. Methods: The study included the period from 1 January 1986 to 31 December 1997, for all people aged over 65 years resident in Madrid, based on mortality due to all causes except accidents (ICD-9 codes 1–799), and circulatory (390–459) and respiratory (460–487) causes. Meteorological variables analysed were: daily maximum temperature, daily minimum temperature and relative humidity. To control the effect of air pollution on mortality we considered the daily mean values of sulphur dioxide (SO2), total suspended particulate (TSP), nitric oxides (NOx), nitrogen dioxide (NO2) and tropospheric ozone (O3). Univariate and multivariate ARIMA models were used. Box-Jenkins pre-whitening was performed. Results: The results yielded by this study indicate a mortality increase up to 28. 4% for every degree the temperature rises above 36.5 °C, with particular effect in women over the age of 75 years and circulatory-cause mortality. The first heat wave that leads to the greatest effects on mortality, due to the higher number of susceptible people and the duration of the heat wave, show an exponential growth in mortality. Furthermore, low relative humidity enhances the effects of high temperature, linking dryness to air pollutants, ozone in particular. Conclusions: Since a warmer climate is predicted in the future, the incidence of heat wave should increase, and more comprehensive measures, both medical and social, should be adopted to prevent the effects of extreme heat on the population, particularly the elderly.

The generation of Lagrangian chaos has been studied experimentally in a twisted duct flow, a configuration representing a three-dimensional steady open flow in which various signatures of Lagrangian chaos are documented. The twisted duct consists of four 90∘ bends of square cross-section; the plane of curvature of each bend is at 90∘ to that of its neighbors. Dean roll-cells, generated

Episodes of population growth and decline leave characteristic signatures in the distribution of nucleotide (or restriction) site differences between pairs of individuals. These signatures appear in histograms showing the relative frequencies of pairs of individuals who differ by i sites, where i = 0, 1, . . . . In this distribution an episode of growth generates a wave that

Internet was designed for network services without any intention for secure communication. Exponential growth of internet and its users have developed an era of global competition and rivalry. Denial of service attack by multiple nodes is capable of disturbing the services of rival servers. The attack can be for multiple reasons e. g. extortion or to beat the rivals. Peer

Cell viability was improved by supplemental feeding of amino acids and vitamins in batch culture of hybridoma cells. Cells could be maintained over a 10 day period following exponential growth at a constant viable cell concentration of 2.1×106 cells/ml. Concentrations of monoclonal antibody (MAb) reached 140 mg/l, a value of nearly four times that found in typical batch culture. Lactate formation appeared to occur only during active exponential growth and not during the stationary phase.

Given a data set consisting of a large number of pre- dictors plus a response, the problem addressed in this work is to select a minimal model which correctly predicts the response. Methods for achieving this subsetting of the predictors have been the topic of a considerable amount of study within the statistics community. Unfortunately, current methods often fail when

This chapter has two goals. The first goal is to compare Machine Learning (ML) and Knowledge Discovery in Data (KDD, also often called Data Mining, DM) insisting on how much they actually differ. In order to make my ideas somewhat easier to understand, and as an illustration, I will include a description of several research topics that I find relevant to KDD and to KDD only. The second goal is to show that the definition I give of KDD can be almost directly applied to text analysis, and that will lead us to a very restrictive definition of Knowledge Discovery in Texts (KDT). I will provide a compelling example of a real-life set of rules obtained by what I call KDT techniques.

Data Mining has become a buzzword in industry in recent years. It is something that everyone is talking about but few seem to understand. There are two reasons for this lack of understanding: First is the fact that Data Mining researchers have very diverse backgrounds such as machine learning, psychology and statistics. This means that the research is often based on different methodologies and communication links e.g. notation is often unique to a particular research area which hampers the exchange of ideas and the dissemination to the wider public. The second reason for the lack of understanding is that the main ideas behind Data Mining are often completely opposite to mainstream statistics and as many companies interested in Data Mining already employ statisticians, such a change of view can create opposition.

Municipal solid waste (MSW) is the abridgment of the waste generated from domestic, commercial, and construction activities by natural persons that is collected and treated by municipalities. Exponential growth of population and urbanization, and the development of social economy, coupled with the improvement of living standard, have resulted in an increase in the amount of MSW generation throughout the world. On average the developed countries typically generate 521.95–759.2 kg per person per year (kpc) and 109.5–525.6 kpc typically by developing countries. Recent estimates suggest that the MSW generation globally exceeds 2 billion tons per year, which is a potential threat to environmental dilapidation. Therefore, MSW management (MSWM) seems to be one of the key topics for environmental protection in present days and also in the future. The authors have illustrated MSW generation and composition analysis and have provided a comprehensive review of MSWM in different countries throughout the world based on the available literatures. Some of the important aspects of waste management, such as composting, landfilling, and incineration, are illustrated.
