pyAmpliCol: fast tree-level matrix elements
Rikkert Frederix, Valentin Hirschi, Lucien Huber +3
Tree-level matrix elements sit at the heart of collider event generation, but their cost rises rapidly just where additional resolved radiation becomes most important. We present p…
Integer Polynomial Factorization by Recombination of Real Factors: Re-evaluating an Old Technique in Modern Era
Shahriar Iravanian
Polynomial factorization over is of great historical and practical importance. Currently, the standard technique is to factor the polynomial over finite fields first and then…
Symbolic-Numeric Integration of Univariate Expressions based on Sparse Regression
Shahriar Iravanian, Carl Julius Martensen, Alessandro Cheli +4
Most computer algebra systems (CAS) support symbolic integration as core functionality. The majority of the integration packages use a combination of heuristic algebraic and rule-b…
Discovery of the Hidden State in Ionic Models Using a Domain-Specific Recurrent Neural Network
Shahriar Iravanian
Ionic models, the set of ordinary differential equations (ODEs) describing the time evolution of the state of excitable cells, are the cornerstone of modeling in neuro- and cardiac…
