J-PLUS : two-dimensional analysis of the stellar population in NGC 5473 and NGC 5485
(2019) [Artigo de periódico]Context. The spatial variations of stellar population properties within a galaxy are intimately related to their formation process. Therefore, spatially resolved studies of galaxies are essential to uncover their formation ... -
J/(psi) suppression in electro-and hadroproduction : a conventional physics explanation
(1994) [Artigo de periódico]Having in mind the importance of the phenomenon for the search for the quark-gluon plasma in the collision of heavy nuclei, we study the suppression of J/Ψ production in leptoproduction and hadroproduction on heavy nuclear ... -
Juice test for identification of nonerosive reflux disease in heartburn patients
(2018) [Artigo de periódico]Background/Aims Evaluation of esophageal clearance by orange juice swallowing could be useful to identify different categories of gastroesophageal reflux disease. We determined whether a juice test at the beginning of ... -
Julia sets are uniformly perfect
(1992) [Artigo de periódico]We prove that Julia sets are uniformly perfect in the sense of Pommerenke (Arch. Math. 32 (1979), 192-199). This implies that their linear density of logarithmic capacity is strictly positive, thus implying that Julia sets ... -
