- In this work, the role of the electric conductivity on variations of the PD phenomenon in XLPE insulation under DC stress is investigated and demonstrated. To enable this investigation, a new experimental setup simulating the insulating layer of a cable with an embedded air void defect and subjected to a DC stress and temperature has been proposed. The setup consists of two flat specimens connected in series. One of them is heated while the other one, that contains the defect, is kept at ambient temperature. Consequently, the electric fields induced by the externally applied DC stress differ between the two specimens. In this way, a conductivity variation between two dielectric layers is obtained. To facilitate the usage of this method, a new simulation model related to the proposed experimental setup has also been developed. The model is an extension of the three-capacitor model, in which variable resistors are introduced. Both simulation and experimental results indicate that the introduced discrete thermal gradient results in higher conductivity values and enhanced PD activity.

- Have you ever sought to use metagenomic DNA sequences reported in scientific publications? Were you successful? Here, we reveal that metagenomes from no fewer than 20% of the papers found in our literature search, published between 2016 and 2019, were not deposited in a repository or were simply inaccessible. The proportion of inaccessible data within the literature has been increasing year-on-year. Noncompliance with Open Data is best predicted by the scientific discipline of the journal. The number of citations, journal type (e.g., Open Access or subscription journals), and publisher are not good predictors of data accessibility. However, many publications in high-impact factor journals do display a higher likelihood of accessible metagenomic data sets. Twenty-first century science demands compliance with the ethical standard of data sharing of metagenomes and DNA sequence data more broadly. Data accessibility must become one of the routine and mandatory components of manuscript submissions-a requirement that should be applicable across the increasing number of disciplines using metagenomics. Compliance must be ensured and reinforced by funders, publishers, editors, reviewers, and, ultimately, the authors.
