Mean-field theory of vector spin models on networks with arbitrary degree distributions
Posted on
by
The structure of a complex network influences any dynamical processes occurring within it. In particular, strong heterogeneities in network structure often underlie nontrivial dynamical properties of networked systems.

A Little Data Goes a Long Way: Automating Seismic Phase Arrival Picking at Nabro Volcano With Transfer Learning
Posted on
by
Seismic monitoring plays a fundamental role in mitigating hazards near volcanoes, where thousands of earthquakes can occur each day during periods of unrest. These events produce a diverse range of seismic signals, and the detection of the initial primary (P-) and secondary/shear […]

Evaluating structural edge importance in temporal networks
Posted on
by
The effect an individual node or edge can have on a network’s structure and dynamics depends not only on the scale of its activity, but also on its position within the network, as well as the activity of neighbouring nodes and edges.

Big jump principle for heavy-tailed random walks with correlated increments
Posted on
by
Since its first formulation in 1964, the so-called “big jump principle” (BJP) of extreme value statistics has played an important role in fields such as large deviation theory and financial mathematics. For heavy-tailed distributions, the principle considers N independent and identically distributed […]

On Generalized Langevin Dynamics and the Modelling of Global Mean Temperature
Posted on
by
For more than half a century, researchers have employed mathematical models to better understand the response of the Earth’s climate to internal fluctuations as well as external perturbations, whether anthropogenic or solar. These models range from highly complex and multi-dimensional general circulation […]

Analytic approach for the number statistics of non-Hermitian random matrices
Posted on
by
The study of random matrices finds many important applications in physics, mathematics, biology, statistics and finance, as random matrix ensembles offer simple but nontrivial models of strongly correlated systems.

Decision-making with distorted memory: Escaping the trap of past experience

Humans make decisions in part by drawing on their previous related experiences. But human memory isn’t exhaustive and complete.

Synchronized and asynchronous modulation of seismicity by hydrological loading: A case study in Taiwan
Posted on
by
Many distinct physical factors help trigger earthquakes, among them the loading of the earth’s crust by water. Many studies have demonstrated a seasonal modulation of seismicity linked to water forcing in volcanic areas, plate boundary zones and other regions.

Urban Science: Integrated Theory from the First Cities to Sustainable Metropolises
Posted on

The emergence of cities is a relatively recent phenomenon in human history. Their appearance in the archaeological record coincides with the advent of increasingly sedentary, agricultural, bureaucratic, and politically asymmetrical societies.

Ranking earthquake forecasts using proper scoring rules: binary events in a low probability environment
Posted on
by
Probabilistic earthquake forecasts estimate the spatial and/or temporal evolution of seismicity and offer practical guidance to authorities during earthquake sequences, especially following notable earthquakes.
