Abstract

fetched live from OpenAlex

As a simplified stent model, fully-developed flow of an incompressible, Newtonian fluid through a curved tube with axially aligned wall protuberances is investigated to define the impact of stent implantation on hemodynamic behavior in curved vessels. According to previous research local hemodynamics tends to trigger biochemical pathways that result in the inception and progression of in-stent restenosis (ISR) and ultimately lead to stent failure. In this manuscript, we focus on hemodynamic changes due to stent strut protrusion into the vessel lumen as a facilitator of ISR. We investigate a range of physiologically relevant stent strut heights and flow parameters using computational fluid dynamics (CFD).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
