Dear Mr. president,

 

On behalf of a group of Tau enthusiasts, we request an investigation into research misconduct with many connections to ASE.

Why We Measure Tau?

Tau and Beyond

Tau renders us a new approach to the cardiac function assessment. Since Tau is directly related to how powerful the muscle is at the beginning of diastole, it is well accepted as the best index to describe diastolic function.

When I read The Emperor’s New Clothes as a kid, I did not take it seriously. Funny though, I did not think it would ever happen for that was just the adults’ wild imagination to fool the kids around. Grown up, I realised this can truly happen in the adults’ world. Jaw dropping, smart and decent people are usually involved.

Mindray had just launched a high-end ultrasound machine DC80, which is the first Tau-measurable ultrasound machine in the world.

With the progress of Doppler and modern computer technology, I believe that only a few RBCs’ leaking will be needed to give us a much understandable and clear regurgitation curve. Theoretically, merely a short part of the curve is enough to calculate the Tau. As long as we are allowed to choose 3 points from within the definition field, we can use the updated formulas to proceed. Let’s assume the 3 points are a (v_a, t_a), b (v_b, t_b) and c (v_c, t_c) from left to right. The updated formulas are:
