Internet World Wide Web Colfiorito earthquake
2015/9/1
The September 26, 1997 Central Italy earthquake represents the first Italian large seismic event on the occasion of which Internet was intensively exploited to exchange and disseminate data, informati...
Using neural networks to study the geomagnetic field evolution
Geomagnetic Field Geomagnetic Observatory Neural Networks (NN) time series time prediction

For decades, alluvial plains have been the areas of the fastest population growth over most of the globe. Modern societies demand growing extensions of flat and easily accessible land to accommodate t...
Geoethics and philosophy of Earth sciences: the role of geophysical factors in human evolution
Philosophy of Earth Sciences Scientific Prediction Nature Probability
2015/8/26
This article explores the role of philosophy of the Earth sciences in the foundation of the principles of ‘geoethics’. In particular, the focus is on two different examples of philosophical analysis i...
Characteristics of flux-time profiles, temporal evolution, and spatial distribution of radiation-belt electron precipitation bursts in the upper ionosphere before great and giant earthquakes
Earthquake precursors particle precipitation wave particle interactions
2015/8/24
The analysis of energetic electron observations made by the DEMETER satellite reveals that radiation belt electron precipitation (RBEP) bursts are observed in general several (~1-6 days) before a larg...
Evolution of Bearing Determination in HF Current Mapping Radars
Bearing Determination HF Current Mapping Radars
2015/8/10
Nearly all target detection "radars" in existence operate at microwave frequencies because their wavelengths are small enough that compact antennas provide both good angular resolution and high sensit...

Measuring and interpreting the optical properties of ocean waters has been, and continues to be a challenging endeavor in oceanography. Just as the measurements of temperature~ salinity and density (T...
A "Sudden Appearance" model for the Evolution of Human Cognition and Language
Evolution Neoteny Saltation
2015/8/3
The debate over the evolution of an innate language capacity seems to divide into two principle schools of thought. Jackendoff (1999a, 1999b) has argued that language processing is based on three auto...

Largest-Scale Trend Organismal Evolution
2015/7/31
The idea that there are any large-scale trends in the evolution of biological organisms is
highly controversial. It is commonly believed, for example, that there is a large-scale trend in
evolution ...
