Applied Sciences, Vol. 16, Pages 9211: Smartphone-Based Estimation of Ground Reaction Forces and Lower-Limb Kinematics During Functional Tasks Using OpenCap: A Feasibility Study
3+ min ago (465+ words) (1) Background: Markerless motion capture may enable scalable biomechanical assessment outside laboratory environments, yet its applicability to tasks involving elevated foot contacts and rapid loading transitions remains insufficiently characterized. This feasibility study evaluated OpenCap, an open-source smartphone-based markerless system, for estimating…...
"Money we gave back to shoppers" matches no table name. Four searches find it anyway.
46+ min ago (568+ words) Someone asks your text-to-SQL agent: "money we gave back to shoppers." The table that answers it is called billing_credit_note. Those two strings share no word. Not a low score — zero overlap. Any retriever that works on table names is blind here,…...

I’d start with what the application actually does: synchronous text requests, occasional image generation, thousands of queued video jobs, or inference behind enterprise IAM. Those are different operating models. A single…...
