Environmental change is triggering an identity switch in grasslands（图）
Environmental change triggering identity switch grasslands
2019/10/21
Since the first Homo sapiens emerged in Africa 300,000 years ago, grasslands have sustained humans and thousands of other species. Today, those grasslands are shifting. Global change -- including clim...
Evidence for tidal triggering for the earthquakes of the Ionian geological zone, Greece
Lunisolar Tides Seismicity
2015/8/24
We here investigate the evidence for tidal triggering of the earthquakes of the seismic area of the Ionian geological zone in Greece, using the cumulative histogram method that was introduced recently...
Plant hormone has dual role in triggering flower formation, Penn study finds
Plant hormone dual role triggering flower formation Penn study finds
2014/6/12
Flowers aren’t just pretty to look at, they are how plants reproduce. In agricultural plants, the timing and regulation of flower formation has economic significance, affecting a crop’s yield.
Triggering of Aftershocks of the Japan 2011 Earthquake by Earth Tides
Japan 2011 earthquake, Aftershock Triggering, Earth tides
2011/9/1
The aftershock sequence of the devastating Japan earthquake of March 2011 is analyzed for the presence of periodicities at the Earth tide periods. We use spectral analysis as well as a time-domain met...
Discrimination of Membrane Antigen Affinity by B cells Requires Dominance of Kinetic Proofreading over Serial Triggering
Membrane Antigen Affinity B cells Requires Dominance
2011/1/5
B cells receptor (BCR) signaling in response to membrane-bound antigen increases with antigen affinity, a process known as affinity discrimination. We use computational modeling to show that B cell af...
A Supersymmetric model for triggering Supernova Ia in isolated white dwarfs
Supersymmetric model Supernova Ia
2010/11/11
In a two parameter phase transition model we fit the rate and several properties of type I super-novae and address the gap in the supermassive black hole mass distribution. One parameter is a critical...
Starburst radio galaxies: general properties, evolutionary histories and triggering
galaxies active – galaxies jets – galaxies starburst – galaxies:interactions
2010/11/12
In this paper we discuss the results of a programme of spectral synthesis modelling of
a sample of starburst radio galaxies in the context of scenarios for the triggering of the
activity and the evo...
Forming Planetesimals by Gravitational Instability: I. The Role of the Richardson Number in Triggering the Kelvin-Helmholtz Instability
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/23
Gravitational instability (GI) of a dust-rich layer at the midplane of a gaseous circumstellar disk is one proposed mechanism to form planetesimals, the building blocks of rocky planets and gas giant ...
Triggering up states in all-to-all coupled neurons
Slow-wave sleep cortical Up/Down states mammalians
2010/4/6
Slow-wave sleep in mammalians is characterized by a change of large-scale cortical activity currently paraphrased as cortical Up/Down states. A recent experiment demonstrated a bistable collective beh...
Triggering collective oscillations by three-flavor effects
collective oscillations three-flavor effects
2010/3/15
Collective flavor transformations in supernovae, caused by neutrino-neutrino interactions, are essentially a two-flavor phenomenon driven by the atmospheric mass difference and the small mixing angle ...
Relations between rainfall and triggering of debris-flow:case study of Cancia(Dolomites,Northeastern Italy)
rainfall triggering debris-flow ase study Cancia
2009/12/11
Debris-flows occurring in the area of Cancia (Dolomites, Northeastern Italy) in recent years have exposed the population to serious risk. In response to the recurring hazard, an alarm and monitoring s...
Seismic triggering of landslides,Part A:Field evidence from the Northern Tien Shan
Seismic triggering landslides Field evidence Northern Tien Shan
2009/12/11
Landslides triggered by strong earthquakes often caused most of the global damage and most of all casualties related to the events, such as shown by the M = 7.7 Peru earthquake in 1970, by the M = 7.6...
Seismic triggering of landslides. Part B: Simulation of dynamic failure processes
Seismic triggering landslides dynamic failure processes
2009/12/10
From field observations it is possible to establish correlations between geological conditions and landslide occurrence. However, in general, it is difficult to assess the affect of individual factors...

Soft-sediment deformation structures Late Silurian Stubdal Formation seismic triggering
2009/12/3
The Ringerike Group is a lower Old Red Sandstone fluvial sequence that forms part of the Late Silurian foreland basin succession of the Ringerike Group, Oslo Region, southern Norway. The Ringerike Gro...
Frequency and triggering mechanisms of submarine landslides of the North Norwegian continental margin
Frequency triggering mechanisms submarine landslides North Norwegian continental margin
2009/12/3
The frequency of submarine landslides was investigated through the occurrence of sandy turbidites in a 16 m long piston core and a shorter gravity core from the abyssal plain of the Lofoten Basin, Nor...
