Impact of the Peterlin approximation on polymer dynamics in turbulent flows [PDF]
Physical Review E, 2015 We study the impact of the Peterlin approximation on the statistics of the end-to-end separation of polymers in a turbulent flow. The finitely extensible nonlinear elastic (FENE) model and the FENE model with the Peterlin approximation (FENE-P) are numerically integrated along a large number of Lagrangian trajectories resulting from a direct numerical ...

Approximation through suffixation: -ḍḍu/-a in Sicilian
Zeitschrift für Wortbildung, 2023 This article investigates the use of the Sicilian suffix -ḍḍu/-a for the expression of approximation. On the basis of a survey of a corpus of ethnotexts and the outputs of a translation questionnaire, we propose that approximation is a core value in the ...

Ensemble-based approximation of observation impact using an observation-based verification metric [PDF]
Tellus: Series A, Dynamic Meteorology and Oceanography, 2016 Knowledge on the contribution of observations to forecast accuracy is crucial for the refinement of observing and data assimilation systems. Several recent publications highlighted the benefits of efficiently approximating this observation impact using ...

Impact of cost approximation on the efficiency of collaborative regulation resolution mechanisms [PDF]
, 2023 Air Traffic Flow Management (ATFM) measures are often used to alleviate capacity demand imbalances. Usually, these measures impose a departure delay on flights crossing the airspace in question, where delay is assigned on a “First Planned First Served ...

A new methodological perspective on the impact of energy consumption on economic growth: time series evidence based on the Fourier approximation for solar energy in the USA [PDF]
, 2020 From the empirical energy literature, it is observed that studies focusing on the energy-economic growth nexus ignore the possible existence of gradual breaks as they employ methods without or with sharp structural breaks.

Approximating spectral impact of structural perturbations in large networks [PDF]
Physical Review E, 2010 Determining the effect of structural perturbations on the eigenvalue spectra of networks is an important problem because the spectra characterize not only their topological structures, but also their dynamical behavior, such as synchronization and cascading processes on networks.

Dimension Free Nonasymptotic Bounds on the Accuracy of High-Dimensional Laplace Approximation
, 2022 This paper aims at revisiting the classical results on Laplace approximation in a modern nonasymp-totic and dimension-free form. Such an extension is motivated by applications to high-dimensionalstatistical and optimization problems.
