Annals of Noninvasive Electrocardiology, Volume 30, Issue 3, May 2025.The LCX is the most prevalent culprit vessel with acute complete occlusion in NSTEMI patients, yet it has little effect on clinical outcomes. This subset of patients may be predicted by STV5 + STV6 ≥ 2.5 mm and T‐wave imbalance. ABSTRACT Background Complete blockage of the culprit coronary artery is associated with 30% of NSTEMI (non‐ST‐segment ...

Study of the properties of Cosmic rays and solar X-Ray Flares by balloon borne experiments [PDF]
, 2013 Indian Centre for Space Physics is engaged in pioneering balloon borne experiments with typical payloads less than ~ 3.5kg. Low cost rubber balloons are used to fly them to a height of about 40km. In a double balloon system, the booster balloon lifts the orbiter balloon to its cruising altitude where data is taken for a longer period of time.

To grow or to shrink: A tale of two rubber balloons [PDF]
arXiv, 2004 Two identical rubber balloons are partially inflated with air (to different extent) and connected by a hose with a valve. It is found that depending on balloon volumes, when the valve is opened the air will flow either from the larger (fuller) balloon to the smaller (emptier) balloon, or from the smaller balloon to the larger one.
