Privacy-preserving quality control of neuroimaging datasets in federated environments.

Privacy concerns for rare disease data, institutional or IRB policies, access to local computational or storage resources or download capabilities are among the reasons that may preclude analyses that pool data to a single site. A growing number of multisite projects and consortia were formed to function in the federated environment to conduct productive research under constraints of this kind. In this scenario, a quality control tool that visualizes decentralized data in its entirety via global aggregation of local computations is especially important, as it would allow the screening of samples that cannot be jointly evaluated otherwise.

Enhanced Light Absorption by Facile Patterning of Nano-Grating on Mesoporous TiO Photoelectrode for Cesium Lead Halide Perovskite Solar Cells.

CsPbIBr, a cesium-based all-inorganic halide perovskite (CsPe), is a very promising alternative material to mainstream organic-inorganic hybrid halide perovskite (HPe) materials owing to its exceptional moisture stability, thermal stability, and light stability. However, because of the wide band gap (2.05 eV) of CsPbIBr, it has a low power conversion efficiency (), which hinders its application in highly efficient solar cells.

Efficient TiO Surface Treatment Using CsCO for Solution-Processed Planar-Type SbS Solar Cells.

We report a highly effective surface treatment method for planar-type SbS solar cells by employing a CsCO-modified compact TiO (c-TiO) electron transport layer. It is found that surface treatment using a CsCO solution can shift the work function of c-TiO upward and reduce its surface roughness. As a result, compared with the power conversion efficiency of untreated solar cells, that of the treated solar cells with a glass/FTO/c-TiO(/CsCO)/SbS/P3HT/Au structure significantly improved from 2.
