The influence of Tidology and Astronomy in Alfred Marshall’s economics: a reassessment of his economic method for the analysis of periodic and secular variations

Evolutionary and Institutional Economics Review, 2021
Alfred Marshall explored a scientific method for theorising complex economic phenomena using mechanical and biological analogies. Moreover from his very first book The Economics of Industry Marshall paid attention to the efficacy of a science of tendencies to understand real economic movements.

Constraining the effective field theory of dark energy with multimessenger astronomy

Physical Review D, 2023
The effective field theory of dark energy predicts a possible time variation of the propagation speed of gravitational waves (GW) which could be tested with multimessenger astronomy. For this purpose we derive the relation between the redshift dependence

Generation of Coherent Signals for the Verification of Signal Processing Algorithms in Radio Astronomy

Pacific Rim Conference on Communications, Computers and Signal Processing, 2019
Next generation radio telescopes (e.g. SKA, ngVLA) are required to meet stringent requirements in signal quality. Simulation methods have been extensively used for both design and verification of the signal chains of these telescopes. A key aspect of the
