Effects of the 6th September 2002 earthquake: damage amplification in the south-eastern sector of Palermo explained by GIS technology
GIS seismic response site effects Palermo
2015/9/17
During the 6th September 2002 earthquake the highest damage level in Palermo was observed in the SE sector.
This is a recent urbanization area where reinforced concrete structures predominate. A deta...
In 2008 scientists from Woods Hole Oceanographic Institution (WHOI) and the University of Washington documented for the first time how the icy bottoms of lakes atop the Greenland Ice Sheet can crack o...
We revisit the problem of introducing an external global field – the mass media – in Axelrod’smodel of social dynamics, where in addition to their nearest neighbors, the agents can interact with a vir...
Cosmic Ray e^+/(e^- + e^+) and pbar/p Ratios Explained by an Injection Model Based on Gamma-ray Observations
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
We present a model of cosmic ray injection into the Galactic space based on recent gamma-ray observations of supernova remnants (SNRs) and pulsar wind nebulae (PWNe) by the Fermi Large Area Telescope ...
Interspecies differences in calcium content and requirement in four freshwater cladocerans explained by biokinetic parameters
Interspecies differences in calcium content in four freshwater cladocerans explained biokinetic parameters
2014/4/17
We tested the hypothesis that cladocerans with higher calcium (Ca) content are more susceptible to Ca limitation by conducting life table experiments using four cladoceran species with contrasting Ca ...
Explained: Dynamo theory--Recent discoveries raise questions about how small planets can have self-sustaining magnetic fields（图）
Dynamo theory small planets self-sustaining magnetic fields
2010/4/21
The Earth’s global magnetic field is generated in its metallic core, located nearly 3,000 kilometers beneath the planet’s surface. The field has existed on Earth for at least 3.5 billion years and off...
Explained: Climate sensitivity（图）
Climate sensitivity the Earth’s greenhouse gases temperature
2010/3/24
Climate sensitivity is the term used by the Intergovernmental Panel on Climate Change (IPCC) to express the relationship between the human-caused emissions that add to the Earth’s greenhouse effect — ...
When people talk about global warming or the greenhouse effect, the main underlying scientific concept that describes the process is radiative forcing. And despite all the recent controversy over leak...

Scaling of small repeating earthquakes explained by interaction of seismic and aseismic slip in a rate and state fault model
Scaling small repeating earthquakes explained by interaction seismic aseismic slip in a rate state fault model
2014/4/8
Because of short recurrence times and known locations, small repeating earthquakes present a rare predictable opportunity for detailed field observations. They are used to study fault creeping velocit...
