Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Cell-culture Data Pipeline Python package (CDPpy) for processing and analyzing cell culture datasets
    (2024-08-05) Lu, Yen-An; Fukae, Yudai; Hu, Wei-Shou; Zhang, Qi; qizh@umn.edu; Zhang, Qi; University of Minnesota Decision Discovery and Optimization Lab; University of Minnesota Cellular Engineering Lab
    CDPpy (Cell-culture Data Pipeline Python package) is an open-source library designed for the analysis of fed-batch cell culture data from multiple experiments and cell lines. The package features the functions of a data processing pipeline and visualization toolbox. The processing pipeline reads raw data from Excel files following a fixed template, derives variables such as cumulative substrate consumption and various specific rates, and exports the processed dataset into an Excel file. The specific rates show changing cellular activities over time in culture, providing insights for process optimization. The visualization toolbox enables users to analyze process profiles across experimental runs and cell lines, aiding in future experimental design. In this repository, we include the source code for the package, an instruction for package setup, and a Jupyter notebook that provides step-by-step guidelines for data processing and visualization using an example dataset. The updated version will be announced in the GitHub repository: https://github.com/ddolab/CDPpy in the future.

    Strategic Design of Expansions of Green Hydrogen Plants – with and without Green Hydrogen Certificates
    (2023) Huang, Jiayi; Rathi, Tushar; Zhang, Qi
    Global temperatures are rising at an alarming rate, leading to severe climatic conditions, and decarbonizing the global economy, such as limiting the use of fossil fuels, is imminent. Accelerating green hydrogen production can provide a much-needed impetus to the goal of a decarbonized economy. More than 95% of the hydrogen used in the U.S. is produced via natural gas reforming and oil reforming which are highly energy-intensive and are significant sources of carbon emission. However, due to difficult geographical terrain or transportation issue, we are proposing a certificate allowing organizations to claim the usage of green hydrogen similar to Renewable Energy Certificates (REC) to stimulate the growth of green hydrogen production facilities.
