We propose novel indices of ventricular repolarization intervals, the JTp/JT, Tpe/JTp and Tpe/JT ratios. These indices have been compared with the duration of the ventricular repolarization intervals and other ratios in 17 normal subjects and 17 patients with old myocardial infarction. In the intervals and other ratios, the best separation between groups is obtained with the Tpe/QTp and Tpe/QT ...

We have previously reported a strong positive association between average day time and nighttime heart rate measured during 24 hour ambulatory blood pressure monitoring and usual alcohol intake. Acute alcohol consumption has been previously described to reduce ECG indices of vagal activity, and men who are severely dependent on alcohol have been reported to have significantly lower indices of c...

The fact that the properties of a molecule are tightly connected to its structural  characteristics  is one of the fundamental concepts in chemistry. In this connection,  graph theory has been successfully applied in developing some relationships between topological indices and some thermodynamic properties. So ,  a novel method for computing the new descriptors to construct a quantitative rela...

This study compares the performances of two sampling-based strategies for simultaneous estimation first- and total-order variance-based sensitivity indices (a.k.a. Sobol’ indices). The first strategy corresponds to current approach employed by practitioners recommended in literature. second one was only recently introduced last authors present article. Both rely on different estimators indices....

The Sombor indices, a new category of degree-based topological molecular descriptors, have been widely investigated due to their excellent chemical applicability. This paper aims establish index distributions in random polygonal chain networks and derive expressions for expected values variances. variances the indices polyonino, pentachain, polyphenyl, cyclooctane chains are obtained. Since end...

Water level monitoring is important for understanding the global hydrological cycle. Remotely-sensed indices that capture localized instantaneous responses have been extensively explored for water level reconstruction during the past two decades. However, the potential usage of the Palmer’s Drought Severity Index (PDSI) and El Niño Southern Oscillation (ENSO) indices for water level reconstruct...

background: breast milk is important for the overall well-being of infants. although lactation is relatively robust in the face of poor nutrition, the implication of poor nutrition on non-nutritive factors in breast milk is inconclusive. objective: this study was designed to find associations between nutritional and immune factors in maternal blood and breast milk with the aim to improve the ne...
