An efficient way to use MS‐CLEAN associated with Shannon's entropy
IET Image Processing, 2021 This article covers deconvolution methods in the context of radio astronomical images. A new formulation is proposed to deal with negative brightness, deconvoluting separately the positive and negative brightness of the sky.

A hundred years of Milutin Milankovic's climate change theory-geological implications [PDF]
Geološki Anali Balkanskoga Poluostrva, 2020 Milanković’s cycles theory published hundred years ago is the most important theory in climate science and had great influence on Earth disciplines. Nevertheless, his work waited for more than fifty years for confirmation.
