A double-branching model applied to long-term forecasting of Italian seismicity (ML≥5.0) within the CSEP project
Earthquake interactions Forecasting
2015/8/28
The purpose of this study was to apply a double-branching model to forecasting of moderate-to-large Italian seismicity within the Collaboratory Study for Earthquake Predictability project. This projec...
The Proportional Hazard Model as applied to the CSEP forcasting area in Italy
Italy CSEP Proportional Hazard Model
2015/8/28
This study presents the strategies adopted to modify the Proportional Hazard Model to fit the requirements for forecasting testing within the Collaboratory Study for Earthquake Predictability (CSEP) e...
LASSCI2009.2: layered earthquake rupture forecast model for central Italy, submitted to the CSEP project
Earthquake rupture forecast Central Italy Model validation Time-dependent seismic hazard assessment
2015/8/28
The Collaboratory for the Study of Earthquake Predictability (CSEP) selected Italy as a testing region for probabilistic earthquake forecast models in October, 2008. The model we have submitted for th...
Geochemical monitoring of volcanic lakes. A generalized box model for active crater lakes
Geochemical monitoring Active crater lakes Box model Mass budget Isotope and chemical budget
2015/8/27
In the past, variations in the chemical contents (SO42−, Cl−, cations) of crater lake water have not systematically demonstrated any relationships with eruptive activity. Intensive paramet...
Numerical simulation of lava flow using a GPU SPH model
GPGPU modeling HPC SPH hazard lava
2015/8/27
A smoothed particle hydrodynamics (SPH) method for lava-flow modeling was implemented on a graphical processing unit (GPU) using the compute unified device architecture (CUDA) developed by NVIDIA. Thi...
Dynamics of a model of two delay-coupled relaxation oscillators
Coupled oscillators Devil’s Staircase Delay-differential equations
2015/8/27
This paper investigates the dynamics of a new model of two coupled relaxation oscilla-tors. The model replaces the usual DDE (differential-delay equation) formulation with a discrete-time approach wit...
A digital model of coupled oscillators
Coupled oscillators Synchronization Digital oscillator
2015/8/27
A new model of coupled oscillators is proposed and investigated. All phase variables and parameters are integer-valued. The model is shown to exhibit two types of motions, those which involve periodic...
Repeat station data compared to a global geomagnetic field model
Geomagnetic repeat station data crustal bias
2015/8/26
Geomagnetic repeat station surveys with local variometers for improved data reductions have been carried out in Germany for about ten years. For nearly the same time interval the satellites Ørste...
A signal-strength model for gravity-field spectrum components in a local space
Earth's Gravitational Potential Local Area Spectrum Structure Spherical Cap Harmonic Analysi
2015/8/26
In the Earth gravity-field model, potential coefficients are projections of the Earth gravitational potential on the corresponding spherical harmonics by degree and order. These coefficients reflect t...
Engineering seismic demand in the 2012 Emilia sequence:preliminary analysis and model compatibility assessment
Spectra Ground motion Intensity measures
2015/8/26
The Emilia 2012 sequence featured seven events of moment magnitude (M) >5, five of which occurred between May 20 and May 29, 2012. These earthquakes were structurally damaging over a wide area. The da...
Static stress transfer from the May 20,2012,M 6.1 Emilia-Romagna (northern Italy) earthquake using a co-seismic slip distribution model
Stress Transfer Slip distribution Italy
2015/8/26
We model the static stress transfer for the May 2012 northern Italy earthquakes, assuming that failure of the crust occurs by shear. This allows the mechanics of the process to be approximated by the ...
Dissecting the Phase Response of a Model Bursting Neuron
phase response isochron multiple time-scales
2015/8/25
We investigate the phase response properties of the Hindmarsh–Rose model of neuronal bursting
using burst phase response curves (BPRCs) computed with an infinitesimal perturbation approximation
and ...
A Geometric Model for Mixed-Mode Oscillations in a Chemical System
mixed-mode oscillations bifurcations kneading theory
2015/8/25
This paper presents a detailed analysis of mixed-mode oscillations in the “autocatalator,” a threedimensional,
two time scale vector field that is a chemical reactor model satisfying the law of mass

The Hodgkin–Huxley model was developed to characterize the action potential of a squid axon. It has
served as an archetype for compartmental models of the electrophysiology of biological membranes.
