Free radicals #5: Hydroxyl radical (β€’OH) is a dangerous free radical. The only defense is preventing its formation as all its reactions are nearly at the same very fast rate. To be 50% effective, a scavenger would have to be at a concentration equal to all of other reacting compounds combined. πŸ§ͺ

graphrag/graphrag/prompts/index/entity_extraction.py at main Β· microsoft/graphrag A modular graph-based Retrieval-Augmented Generation (RAG) system - microsoft/graphrag

Earlier this year, Microsoft published GraphRAG, an alternative to vector similarity based RAG everyone is using. Goal: can also answer queries like "What were the top 5 most prominent topics in all the documents".

They open-sourced the system, including the prompts to construct the entity graph.

Why probability probably doesn’t exist (but it is useful to act like it does) All of statistics and much of science depends on probability β€” an astonishing achievement, considering no one’s really sure what it is.

An essay in Nature discusses how it’s an astonishing achievement that all of statistics and much of science depends on probability considering no one’s sure what it is. πŸ§ͺ

Top: ECG trace from a patient in asystole, showing movement caused by CPR. Bottom: Same ECG with impedance trace (yellow), confirming CPR is being performed. The apparent rhythm in the ECG is 100% artifact from chest compressions, highlighting the importance of artifact removal for accurate rhythm interpretation.

The apparent rhythm in the ECG is 100% artifact from chest compressions, highlighting the importance of artifact removal for accurate rhythm interpretation.

CPR artifact can mask a patient’s true rhythm. This patient is in asystole, but CPR motion creates a rhythm-like trace, confirmed by the impedance trace. Advanced AED tech must separate artifact from real rhythms. How can we refine these algorithmsβ€”or do we need to? πŸš‘ #CPR #AED #Asystole
