Elliptic polylogarithms and iterated integrals on elliptic curves. II. An application to the sunrise integral [PDF]
Physical Review D, 2017 We introduce a class of iterated integrals that generalize multiple polylogarithms to elliptic curves. These elliptic multiple polylogarithms are closely related to similar functions defined in pure math- ematics and string theory.

A multi-optimization model for the design of hydrogen supply chains [PDF]
E3S Web of Conferences, 2020 This paper presents a multi-objective optimization models which operating as time processes (2025-2035) for the design of hydrogen supply chain. The feasibility of the models are illustrated through a detail case study of Dalian, China.

Electrodynamics of the equatorial F-region ionosphere during pre-sunrise period [PDF]
Annales Geophysicae, 2009 The electrodynamics of the pre-sunrise equatorial F-region is investigated using HF Doppler radar and digital ionosonde. The observations are limited to those days for which the radar probing frequency is below the foF2 value.

Sunrise: Polychromatic Dust Radiative Transfer in Arbitrary Geometries [PDF]
Mon.Not.Roy.Astron.Soc.372:2-20,2006, 2006 This paper describes Sunrise, a parallel, free Monte-Carlo code for the calculation of radiation transfer through astronomical dust. Sunrise uses an adaptive-mesh refinement grid to describe arbitrary geometries of emitting and absorbing/scattering media, with spatial dynamical range exceeding 10^4, and it can efficiently generate images of the ...

, 2020 In this talk, we discuss our recent computation of the two-loop sunrise integral with arbitrary non-zero particle masses. In two space-time dimensions, we arrive at a result in terms of elliptic dilogarithms. Near four space-time dimensions, we obtain a result which furthermore involves elliptic generalizations of Clausen and Glaisher functions.
