The scores ranged from 1 to 5: intakes or activity much less than habitual (1 point); slightly less (2 points); the same (3 points); slightly more (4 points); far more (5 points). 2.7. Statistical analysis Statistical analyses were conducted using SAS 9.1.3. All continuous variables ...
Then, proceed the discrimination of the next IMF until the first point which exceeds the bounds is found. Therefore, the discrimination can be achieved one by one from the low order IMF to the high order one during the decomposition. The strategy is formulated as: ỹ=∑j=indMcj(n)+rM...

a 3D ECG-gated cine image as a function of cardiac cycle, obtained at 7 T at 104 μm isotropic resolution after injection of USPIO at 200 μmol Fe/kg. Short axis: upper panel; long axis: lower panel. No respiratory gating was used. The arrow (image 6) indicates the aortic valve. ...
If the velocity, v of every point in the object is known, an equivalent definition of the strain rate isɛ.=δvδr(3) The equations also provide a useful description of the deformation of the tissue segment. The strain rate measures the rate of the deformation of the se...
point where the minimum peak of the spike waveform is located (\(i=1,\ldots,{s}^{k}\)). To select windows of the first half batch, we chose\(\frac{B}{2}\)peaks\({n}_{{i}_{j}}^{{k}_{j}}\), by picking out the electrodes and their corresponding spikes {\({k}_{j}...
Additionally, we did not use a clinical risk-stratification tool (eg, Emergency Department Assessment of Chest Pain Score [EDACS]; History, ECG, Age, Risk Factors, and Troponin [HEART] Score; or Thrombolysis In Myocardial Infarction [TIMI] Score). This has the advantage of avoiding reliance ...
In addition to baseline hs-cTnT levels and absolute hs-cTnT changes within the first hour, age (as a continuous variable), sex, ECG features (signs of ischemia or not) and time since onset of symptoms (as a continuous variable) were included in the CART model as well. The algorithm ...
