Percolation appears as a ubiquitous phenomenon in nature, with significant practical relevance in the study of networks. Its origins connect to the pioneering work of Paul Flory in 1940 and the foundational research of Broadbent and Hammersley in 1957, which established its intricate mathematical principles,, incorporating concepts from probability, physics, and graph theory. In a network composed of nodes and edges, understanding how percolation operates enables researchers to evaluate the effects of adding or removing an edge or a node […]

Women are entering the medical and scientific community in growing numbers, reaching and even surpassing their male counterparts in medical schools. However, a settled imbalance between men and women is still a reality in the international cardiology community despite these recent advances. The female presence in Brazilian medical schools was barely noticed until the 1960s; in the following years, there was a gradual increase in the number of women in the medical field, mainly in the first decade of the […]
