Notes from the STEM Community Call, November 3, 2016
On the call: James Kaufman, Stefan Edlund, Kun Hu, Matthias Filter, Emily Nixon, Judy Douglas
The next call will be in early December; date to be announced
Introductions: Emily Nixon, PhD student at the University of Bristol in the UK, doing mathematical modeling of disease in sheep
1. STEM Integration Build is up, stable
*Stefan: Will do formal Milestone with Eclipse in the next few weeks
*Date for new version: Deferred until ready to do new feature work
2. Ongoing Feature Work, no updates
*Nereyda (not on call): Using STEM to model pandemics in biodefense
3. Updates: Kun
*Primary concern of Santa Clara public health officials is TB (hard to model)
*Interest in Zika in Brazil, Southeast Asia
*Will meet with Singapore Minister of Health in December (100s of reported; multiply by 5 since only 1 in 5 symptomatic)
*Will work with 6 IBMers in Panama on collecting info in real time using mobile devices, on the street interviews (in one of 5 projects selected by IBM)
*Philippine team’s work on model on hookworm infection appears to be proceeding without difficulty
*Sent Werner slides for his presentation at Eclipse Europe
4. Other Work: Jamie
*Roslyn (Australia IBM) worked with Taiwan CDC, taught STEM and new dengue model using interventions (another one of the 5 projects)
5. Bugs: None
6. Discussion
MODELING
*Emily: In looking at disease in sheep on neighboring farms, did a lattice; didn’t fit with map coordinates for UK; slow work. A quicker way?
*Jamie: Perhaps a square lattice; Chris Thoens did something like this; asks Emily to place a feature request on stem-dev requesting a lattice graph inside a polygon; advises phase has to be right
*Emily: How to define county to county spread?
*Jamie: Typically model at highest resolution, use containment nodes, perhaps aggregate farms
*Stefan: Use migration edges between farms, connect up to a central node
*Emily: Some farms use common grazing
*Jamie: Flatten model; don’t use admin zones; label farms, roll up results, then do cross county
*Jamie: Ability to re-export a graph back to Pajet a feature request; Emily can stay with spreadsheet
PROFESSIONAL CONFERENCES
*Emily: Any especially helpful?
*Jamie: Epidemics (USA-based); International Society for Veterinary Epidemiology and Economics (ISDEE) in 2018 in Bangkok
POSSIBLE HACKATHON AT BfR
*Matthias: Has master’s student, invites Emily to BfR; will look at Chris’ salmonella model; will communicate with Emily via email
STEM USER INTERFACE
*Matthias: Took his master’s student 14 days to get STEM running (Java issues)
*Jamie: No internal funding for STEM, but committed to open source project; asks Matthias to articulate what he’d like
*Matthias: At IBM’s 5 selected projects, create additional videos on using STEM
*Jamie: Matthias’ student could make a You Tube video about his problems; IBM team could highlight, put on wiki; need to leverage the open source community
7. Items from Participants
*Stefan: After 10 years, will be putting STEM build on a new server, will run faster
*Emily: How to update? Jamie: Doc on wiki; don’t need to update every week; do NOT delete old version; all your work is there; currently a Windows problem with updates, will help Emily with this
*Judy: Lancet piece on potential Zika threat in Pakistan; Kun commented it seems on target
