Impact picture and the eikonal approximation
Physics Letters B, 1971 Abstract A detailed study of the o 3 -theory shows that the impact picture is correct, while the eikonal approximation is not valid. We discuss a relatively simple experimental test, at the CERN Intersecting Storage Ring, of the impact picture.

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 ...

Making Time Series Embeddings More Interpretable in Deep Learning
Proceedings of the International Florida Artificial Intelligence Research Society Conference, 2023 With the success of language models in deep learning, multiple new time series embeddings have been proposed. However, the interpretability of those representations is often still lacking compared to word embeddings. This paper tackles this issue, aiming

SoftwareX, 2016 Random Phase Approximation (RPA) is one of the main approximation tools in studying nuclear structure. Here, we present a graphical user interface (GUI) Fortran code: Particle–Particle Random Phase Approximation (PPRPA) version 1, 2015. The code performs

The Gluon Impact Factors [PDF]
, 1999 We calculate in the next-to-leading approximation the non-forward gluon impact factors for arbitrary color state in the $t$-channel. In the case of the octet state we check the so-called "second bootstrap condition" for the gluon Reggeization in QCD ...

Atomic Lithium Excitation by Electron Impact
Journal of Kufa-Physics, 2019 Bethe approximation had been used to compute the excitation cross section in term of the diploe oscillator strength for some allowed transitions between energy levels of Li-atom collide with electrons with impact energy range (2-2000) eV. We also compute

Extending the Eikonal Approximation to Low Energy [PDF]
, 2014 E-CDCC and DEA, two eikonal-based reaction models are compared to CDCC at low energy (e.g. 20AMeV) to study their behaviour in the regime at which the eikonal approximation is supposed to fail.

The impact factor for the virtual photon to light vector meson transition
, 2004 We evaluate in the next-to-leading approximation the forward impact factor for the virtual photon to light vector meson transition in the case of longitudinal polarization. We find that in the hard kinematic domain, both in the leading and in the next-to-

Ensemble-based approximation of observation impact using an observation-based verification metric
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 ...

Modelling of tsunami-like wave run-up, breaking and impact on a vertical wall by SPH method [PDF]
Natural Hazards and Earth System Sciences, 2013 Accurate predictions of wave run-up and run-down are important for coastal impact assessment of relatively long waves such as tsunami or storm waves. Wave run-up is, however, a complex process involving nonlinear build-up of the wave front, intensive ...
