QCD vacuum replicas are metastable [PDF]

open access: yesEPJ Web of Conferences, 2022
We study the meson spectra in the excited QCD vacua, denominated replicas. We find all mesons have real masses, with no tachyons, thus showing the QCD replicas are indeed metastable.

A novel method for geometric quality assurance of rock joint replicas in direct shear testing – Part 2: Validation and mechanical replicability

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
Each rock joint is unique by nature which means that utilization of replicas in direct shear tests is required in experimental parameter studies. However, a method to acquire knowledge about the ability of the replicas to imitate the shear mechanical ...

The immersive cave: the multimediality of prehistory between drawing, photography, cinema and 3D

open access: yespiano b, 2022
The prehistoric cave can be considered a paradigmatic "image-environment" for its intimate relationship between images (rock paintings, graffiti, carved blocks) and the wall's geological morphology.
