conclusions large-scale studies on the healthy black african population could assess the relationship between diastolic dyssynchrony and changes in myocardial performance related to racial differences. results the frequency of some dyssynchrony markers was similar to that of other studies. the difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity w...

The paper illustrates a method for the design of suitable controllers of chaotic systems characterized by complex peak-to-peak dynamics, namely by a recursive relationship between consecutive peaks (relative maxima) of a scalar output variable. For such systems, a reduced model can be defined which, in general, is a hybrid model composed of a one-dimensional map and a finite-state automaton. Th...

conformity of miracle of every prophet with the prevailing art and occupation of every time is a well-known matter among scholars. such a theme is narrated for the first time through a chain of transmitters from the 10th shi‘a imam (al-hadi), though it is attributed to the 8th imam (al-rida). as the chain of transmission of the hadith is poor, investigation of its theme is necessary. in this ha...
