A strongly correlated insulator, samarium mono-sulfide (SmS), presents not only the pressure-induced insulator-to-metal transition (IMT) with the color change from black to golden-yellow but also current-induced IMT (CIMT) with negative resistance. To clarify the origin of the CIMT of SmS, the electronic structure change has been investigated by optical reflectivity and angle-integrated photoelectron spectra by applying an electric current. At lower temperatures than about 100 K, where the nonlinear V-I curve has been observed, the carrier density rapidly increases, accompanied by decreasing relaxation time of carriers with increasing current. Then, the direct gap size increases, and the mean valence changes from Sm2+-dominant SmS to the mixed-valent one with increasing current. These results suggest that the CIMT originates from increasing the Sm 4f-5d hybridization intensity induced by the applied current. [ABSTRACT FROM AUTHOR]

The growth of omic data presents evolving challenges in data manipulation, analysis, and integration. Addressing these challenges, Bioconductor 1 provides an extensive community-driven biological data analysis platform. Meanwhile, tidy R programming 2 offers a revolutionary standard for data organisation and manipulation. Here, we present the tidyomics software ecosystem, bridging Bioconductor to the tidy R paradigm. This ecosystem aims to streamline omic analysis, ease learning, and encourage cross-disciplinary collaborations. We demonstrate the effectiveness of tidyomics by analysing 7.5 million peripheral blood mononuclear cells from the Human Cell Atlas 3 , spanning six data frameworks and ten analysis tools., Competing Interests: Competing interest R.G. has received consulting income from Takeda and Sanofi, and declares ownership in Ozette Technologies.
