The sequence is also assigned to several other technical papers in physics and materials science:

The most widely cited paper with this ID is titled

Improving heat transfer in industrial cooling systems using "miniature W-shaped ribs".

A Physical Review Letters paper (131.121901) measuring hadron production ratios in proton-proton collisions.

Active caspase-8 was found to be significantly increased in the brain tissue of human MS patients, suggesting this pathway is a potential target for new MS therapies. 2. Engineering & Heat Transfer: Serpentine Cooling Channels

The study reveals that a specific protein complex (IRAKM–caspase-8–ASC) forms in the brain's immune cells (microglia) when stimulated. This leads to the release of inflammatory cytokines like IL-1β, which drives the progression of CNS inflammation and MS symptoms.

The paper explores "wave focusing effects," which are techniques used to concentrate wave energy into a smaller area to increase the efficiency of power capture. 4. Other Notable Scientific "121901" Articles
