new set of algorithms with which to evaluate the impact of published scientific research. Basing their investigation on PageRank used by Google, they proposed a similar system of ranking scientific papers and authors. Researchers had "mixed reaction", suggesting that it would be useful for "lifetime achievement" but possibly subject to "transparency issues". The "simplicity" of current methods of evaluation allows for gaming the system. The difference in Strumia and Torres' approach is that they include what they describe as "second-generation" and later-generation citations in their algorithms. Therefore, not only the original citations of the work are taken into account, but subsequent citations to derivative material also. They named their systems PaperRank and AuthorRank. They also proposed a system called CitationCoin to reduce the effect of groups who "inflate" each other citation count. Controversies Using pictures of conference slides Marco Cirelli and Alessandro Strumia were amongst multiple teams that used digital photos from a conference presentation by other authors in 2008 in Stockholm for a subsequent publication. The presentation showed a highly anticipated but yet unpublished measurement of the positron fraction in cosmic rays by the PAMELA collaboration. Talk on gender discrimination On 28 September 2018, Strumia gave a presentation at CERN's first Workshop on High Energy Theory and Gender that provoked considerable controversy. Citing an analysis he had performed on data from the InSpire database, he tested the idea that there is a gender bias against women within the academic circles of physics. He claimed that his results suggest that male scientists were victims of discrimination. On 30 September 2018, CERN released a short statement, removed the slides of Strumia's presentation from its conference website and on 1 October, suspended him from his "invited scientist" position, due to a breach of Code of Conduct (naming a CERN employee in the presentation). On 1 October 2018, the University of Pisa released a statement signaling the opening of an ethical investigation and subsequently sanctioned him. Strumia's talk was condemned in a public letter titled “High Energy Physics Community Statement” on a website called “Particles for Justice” on 2 October. As of 13 October, it received nearly 4,000 signatures from scientists working in High Energy Physics and related fields, including those of John Ellis, Howard Georgi and David Gross. In response, a rebuttal titled "Justice For Strumia" was published online along with a petition for reinstatement of Strumia. Subsequently, the petition and the
