Science Highlights
Collaboration Develops AI Tool for "Long Tail" Stamp Recognition in Japanese Historic Documents
XSEDE systems and expertise power study of business document that promises better automated analysis of datasets with numerous rare items, a key limitation in artificial intelligence
Despite its promise, artificial intelligence (AI) can fail – infamously – when its training dataset isn't fully representative of the real world. The MiikeMineStamps dataset offers an historical and social science goldmine in studying business practices in Japan and elsewhere, but its "long tail" of rare stamps poses a big training-dataset challenge. Using XSEDE's Extended Collaborative Support Services and XSEDE-allocated computation, scientists created a new active-learning-based AI that leverages a training dataset with good representation of the MiikeMineStamps data. The method holds promise for addressing training-dataset-driven failures of AI.

Cell's Energy Secrets Revealed with Supercomputers
XSEDE allocations help develop most detailed model yet of mitochondrial protein-protein complex
It takes two to tango, as the saying goes.
This is especially true for scientists studying the details of how cells work. Protein molecules inside a cell interact with other proteins, and in a sense the proteins dance with a partner to respond to signals and regulate each other's activities.
Crucial to giving cells energy for life is the migration of a compound called adenosine triphosphate (ATP) out of the cell's powerhouse, the mitochondria. And critical for this flow out to the power-hungry parts of the cell is the interaction between a protein enzyme called hexokinase-II (HKII) and proteins in the voltage-dependent anion channel (VDAC) found on the outer membrane of the mitochondria. Thanks to XSEDE allocations, supercomputer simulations have revealed for the first time how VDAC binds to HKII.

Improving Geomagnetic Storm Research
XSEDE allocations used for solar wind study
Both satellite and ground-based telecommunications systems can be impacted by geomagnetic storms, such as the one triggered by a powerful explosion on the surface of the sun that took down a Canadian power grid back in 1989. Scientists are working to better understand these strong, mysterious storms by validating data from NASA's Parker Solar Probe with help from an XSEDE allocation. These supercomputer-generated simulations are helping scientists better understand how solar wind is heated to such a high temperature (sometimes above one-million degrees) as well as how solar wind is accelerated to very high speeds (often faster than one-thousand miles per second). In turn, this information can help with solar wind forecasting.

Program Announcements
XSEDE Cyberinfrastructure Integration (XCI) Updates
Globus has released a 3.0 version of its command-line interface, the Globus CLI, which now provides support for Globus Connect Server version 5, profile switching, listing groups you belong to, a simpler interface for specifying file lists, and improved token storage. 
Help Engage Undergrads in the Work of XSEDE!
An XSEDE-wide effort is underway to expand the community by recruiting and enabling a diverse group of students who have the skills — or are interested in acquiring the skills — to participate in the work of XSEDE. The name of this effort is XSEDE EMPOWER (Expert Mentoring Producing Opportunities for Work, Education, and Research). We invite the whole community to recruit and mentor undergraduate students to engage in a variety of activities, such as computational and/or data analytics research and education in all fields of study, networking, system maintenance and support, visualization, and more. The program provides a stipend for students who work on projects for one semester or one quarter.
To participate, undergraduate students from any U.S. degree-granting institutions are matched with mentors who have projects that contribute to the work of XSEDE. Participation is strongly encouraged for mentors and students belonging to groups historically underrepresented in HPC.
Application deadline for spring 2022 participation: October 29, 2021
