This document describes the online leaderboard public evaluation program, Open Media Forensics Challenge (OpenMFC) 2021-2022. In the report, first, the introduction, objectives, challenges, contributions, and achievements of the evaluation program are

Parametric optimization of an air-liquid interface system for flow through inhalation exposure to nanoparticles: assessing dosimetry and intracellular uptake of CeO2 nanoparticles

September 29, 2021
Author(s)
Lars Leibrock, Harald Jungnickel, Jutta Tentschert, Aaron Katz, Blaza Toman, Elijah Petersen, Frank Bierkandt, Ajay V. Singh, Peter Laux, Andreas Luch
Air-liquid interface (ALI) systems have been widely used in recent years to investigate the inhalation toxicity of many gaseous compounds, chemicals, and nanomaterials and represent an emerging and promising in vitro method to supplement or ultimately

Performance of Reservoir Discretizations in Quantum Transport Simulations

September 29, 2021
Author(s)
Justin E. Elenewski, Gabriela Wojtowicz, Marek Rams, Michael P. Zwolak
Quantum transport simulations require a level of discretization, often achieved through an explicit representation of the electronic reservoirs. These representations should converge to the same continuum limit, though there is a trade-off between a given

Resources for developing reliable and reproducible in vitro test methods

September 29, 2021
Author(s)
Elijah Petersen, Vytas Reipa, Menghang Xia, Monita Sharma
A broad range of in vitro test methods have been developed given their numerous potential advantages over in vivo tests. We describe here key resources and tools to increase the reliability and reproducibility of in vitro test methods.
