In 1977 a search for extraterrestrial intelligence at the Ohio State University Radio Observatory recorded a strong, narrowband, and apparently intermittent emission near the 21 cm hydrogen line. The detection displayed the antenna pattern signature of a transiting celestial radio source but was not repeated in subsequent transit observations. The event has been advanced by some as a candidate ...

We propose the use of Bayesian surprise to detect arbitrary, salient acoustic events. We use Gaussian or Gamma distributions to model the spectrogram distribution and use the Kullback-Leibler divergence of the posterior and prior distribution to calculate how “unexpected” and thus surprising newly observed audio samples are. This way, we efficiently detect arbitrary surprising/salient acoustic ...

Writing a scientific article is not an easy task, but it is definitely a great satisfaction to be able to conclude and publish it. Indeed, each publication is a service we make to the entire scientific community and to the advancement of science even before our personal career. There is and there will not be a final book/article for writing a scientific paper. Therefore, some knowledge is a dec...

We present WOW, a simple GUI platform/framework primarily targeted to elderly users, being developed and used in Vienna Pilot of the SPES project to run various brain stimulation applications designed to help patients with dementia or Alzheimer disease in activating/restoring their memory and recall. This work utilizes our previous experience with similar GUIs in EU projects OLDES and SPES to d...

It has been repeatedly proposed to expand the scope for SETI, and one of the suggested alternatives to radio is the biological media. Genomic DNA is already used on Earth to store nonbiological information. Though smaller in capacity, but stronger in noise immunity is the genetic code. The code is a flexible mapping between codons and amino acids, and this flexibility allows modifying the code ...
