Hunting Common Cold Viruses by Some New Methods

The Taxonomic Position of Common Cold Viruses and Some Others

During recent years workers in several countries have isolated a number of "new" viruses from upper respiratory infections. For some of these viruses claims have been made that they cause common colds. Before accepting such claims it is well to be sure of two things: i) that the viruses can be recovered with reasonable frequency from typical common colds in adults; and ii) that they will reprod...

Some New Methods for Prediction of Time Series by Wavelets

Extended Abstract. Forecasting is one of the most important purposes of time series analysis. For many years, classical methods were used for this aim. But these methods do not give good performance results for real time series due to non-linearity and non-stationarity of these data sets. On one hand, most of real world time series data display a time-varying second order structure. On th...

Viruses and bacteria in the etiology of the common cold.

Two hundred young adults with common colds were studied during a 10-month period. Virus culture, antigen detection, PCR, and serology with paired samples were used to identify the infection. Viral etiology was established for 138 of the 200 patients (69%). Rhinoviruses were detected in 105 patients, coronavirus OC43 or 229E infection was detected in 17, influenza A or B virus was detected in 12...

Asthma and the common cold: can viruses imitate worms?

Some New Convergence Acceleration Methods

The £-algorithm is a general extrapolation method which includes most of the sequence transformations actually known. Some new convergence acceleration methods are derived from the f-algorithm by applying the so-called (^-procedure. The algorithms thus obtained are studied. Some theoretical results are proved and numerical examples are given.
