Nonstationary ETAS models for nonstandard earthquakes
The Annals of Applied Statistics, 2014 The conditional intensity function of a point process is a useful tool for generating probability forecasts of earthquakes. The epidemic-type aftershock sequence (ETAS) model is defined by a conditional intensity function, and the corresponding point ...

Construction of Satisfaction Classes for Nonstandard Models
Canadian Mathematical Bulletin, 1981 AbstractGiven a resplendent model for Peano arithmetic there exists a full satisfaction class over , i.e. an assignment of truth-values, to all closed formulas in the sense of with parameters from , which satisfies the usual semantic rules. The construction is based on the consistency of an appropriate system of -logic which is proved by an analysis ...

Nonstandard models and analytic equivalence relations [PDF]
Proceedings of the American Mathematical Society, 1997 We improve a result of Hjorth concerning the nature of thin analytic equivalence relations. The key lemma uses a weakly compact cardinal to construct certain nonstandard models, which Hjorth obtained using # \# ’s.

Physics Letters B, 1983 Abstract We discuss the problem of generation nonuniversality in different electroweak gauge models and possible consequences for the τ-lifetime and τ-asymmetry.

Seven nonstandard models coupling quantum matter and gravity [PDF]
AVS Quantum Science, 2022 We review seven models which consistently couple quantum matter and (Newtonian) gravity in a nonstandard way. For each of them, we present the underlying motivations, the main equations, and, when available, a comparison with experimental data.

New opportunities for axion dark matter searches in nonstandard cosmological models [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We study axion dark matter production from a misalignment mechanism in scenarios featuring a general nonstandard cosmology. Before the onset of Big Bang nucleosynthesis, the energy density of the universe is dominated by a particle field ϕ described by a

Educational gradients in nonstandard work schedules among mothers and fathers in the United Kingdom
Demographic Research, 2021 Background: Mothers' and fathers' participation in nonstandard employment across children's lives is not well understood in the United Kingdom. Objective: The first objective is to describe the prevalence of nonstandard work schedules (e.g., evenings,
