The search for efficient noble metal-free hydrogen-evolving catalysts is the subject of intense
research activity. A new family of molecular cobalt(II)–polypyridyl catalysts has recently …

… for Q, R, S, or R” waves, ranging from 3 to 10% of the maximum QRS slope value (dermax).
This procedure thus attempts to locate as many of the Q, R, S, and R' peaks as are present. …

Snoring, a symptom which may indicate the presence of the obstructive sleep apnoea syndrome
(OSA), is also common in the general population. Recent studies have suggested that …

The authors evaluate a single-lead threshold based ECG wave boundaries detector with a
QT database developed for validation purposes. They also identify its different sources of …

… R and P are the input correlation matrix and the cross-correlation vector, respectively. In this
case xk is an unit impulse sequence, and so we obtain a simple expression for R … = ptr[R] for …

… If now we minimise the MSE ~ with respect to parameter b, and consider that the R matrix
does not depend on b, we find that the optimum parameter b(b*), which minimises ~ for a fixed …

The role that diet plays in the management of plasma lipid levels is discussed in this review.
It has long been recognized that saturated fatty acids and cholesterol raise the plasma …
