Analysis of corrections to the eikonal approximation [PDF]

open access: yes, 2017
Various corrections to the eikonal approximations are studied for two- and three-body nuclear collisions with the goal to extend the range of validity of this approximation to beam energies of 10 MeV/nucleon.

Methods, algorithms and computer codes for calculation of electron-impact excitation parameters [PDF]

open access: yes, 2014
We describe the computer codes, developed at Vilnius University, for the calculation of electron-impact excitation cross sections, collision strengths, and excitation rates in the plane-wave Born approximation.

Impact picture and the eikonal approximation

open access: yesPhysics 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.

Credit risk contributions under the Vasicek one-factor model: a fast wavelet expansion approximation [PDF]

open access: yes, 2014
To measure the contribution of individual transactions inside the total risk of a credit portfolio is a major issue in financial institutions. VaR Contributions (VaRC) and Expected Shortfall Contributions (ESC) have become two popular ways of quantifying

A visual Fortran 90 program for the two-particle or two-hole excitations of nuclei: The PPRPA program

open access: yesSoftwareX, 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

Approximation through suffixation: -ḍḍu/-a in Sicilian

open access: yesZeitschrift 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

open access: yesProceedings 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

Gate tunnelling and impact ionisation in sub 100 nm PHEMTs [PDF]

open access: yes, 2002
Impact ionization and thermionic tunnelling as two possible breakdown mechanisms in scaled pseudomorphic high electron mobility transistors (PHEMTs) are investigated by Monte Carlo (MC) device simulations.

Self-energy of image states on copper surfaces [PDF]

open access: yes, 1999
We report extensive calculations of the imaginary part of the electron self-energy in the vicinity of the (100) and (111) surfaces of Cu. The quasiparticle self-energy is computed by going beyond a free-electron description of the metal surface, either ...
