Two hundred years ago the Montgolfier brothers first demonstrated to the world that man-carrying "engines for flying" were possible. Their vehicle, however, did not have "artificiall Wings" but was a balloon filled with hot air. (A Brazilian, Bartolomeu de Gusmao, had flown a small unmanned hot air balloon 74 years earlier.') After successful unmanned demonstrations the first recorded free flig...

This paper describes an evolutionary neural network approach to Hang Seng stock index forecast. In this approach, a feedforward neural network is evolved using an evolutionary programming algorithm. Both the weights and architectures (i.e., connectivity of the network) are evolved in the same evolutionary process. The network may grow as well as shrink. The experimental results show that the ev...

Financial markets all over the world have witnessed growing integration within as well as across boundaries, spurred by deregulation, globalization and advances in information technology. However, none of the researches have investigated the trading profitability of models that employed the financial market integration information as input variables especially in the case of day trading. Moreov...

AIM To correlate the length of endoscope hang time and number of bacteria cultured prior to use. METHODS Prospectively, we cultured specimens from 19 gastroscopes, 24 colonoscopes and 5 side viewing duodenoscopes during the period of 2011 to 2015. A total of 164 results had complete data denoting date of cleansing, number of days stored and culture results. All scopes underwent initial cleani...

How broadly expressed transcription factors contribute to tissue-specific gene expression is not well understood. Andzelm, Cherry et al. (2015) demonstrate that myocyte enhancer factor 2D (MEF2D) binds and activates retina-specific regulatory regions by cooperative interaction with the tissue-specific transcription factor CRX.

In recent years, withdrawal of marketed drugs including sertindole, grepafloxacin, and terfenadine owing to prolongation of the length of time between the start of the Q wave and end of the T wave on an electrocardiogram (QT interval) has prompted considerable effort in trying to establish the molecular basis of this potentially lethal phenomenon. In the majority of cases, those chemical entiti...

CASE REPORT A 24-year-old woman, with a history of infantile esotropia and DVD operated on in infancy, had strabismus surgery performed by us. Four months later she presented with a cystic lesion that recurred after drainage and medical treatment. Complete excision of the cystic lesion was therefore performed. DISCUSSION The epithelial cells implanted on the sclera at the time of the most rec...

This certainly is the ideal form of a distributed system, where the “implementation detail” of building a powerful system out of many simpler systems is entirely hidden from the user. Are there any such systems? Unfortunately, when we look at the reality of networked computers, we find that the multiplicity of system components usually shines through the abstractions provided by the operating s...

The history of British cybernetics offers us a different form of science and engineering, one that does not seek to dominate nature through knowledge. I want to say that one can distinguish two different paradigms in the history of science and technology: the one that Heidegger despised, which we could call the Modern paradigm, and another, cybernetic, nonModern, paradigm that he might have app...
