Clar, Christine, Keith L. Dorrington, and Peter A. Robbins. Ventilatory effects of 8 h of isocapnic hypoxia with and without b-blockade in humans. J. Appl. Physiol. 86(6): 1897–1904, 1999.—This study investigated whether changing sympathetic activity, acting via b-receptors, might induce the progressive ventilatory changes observed in response to prolonged hypoxia. The responses of 10 human sub...

Transplant tolerance is an important issue in the clinical practice. Successful transplant depends on the ability to block the rejection of the transplanted organ. Currently, improving transplant tolerance is accomplished using immunosuppressive agents, but having also many toxic effects on the host body. So far, the conventional immunosuppressive therapy with calcineurin inhibitors such as cyc...

a set $s$ of vertices in a graph $g$ is a dominating set if every vertex of $v-s$ is adjacent to some vertex in $s$. the domination number $gamma(g)$ is the minimum cardinality of a dominating set in $g$. the annihilation number $a(g)$ is the largest integer $k$ such that the sum of the first $k$ terms of the non-decreasing degree sequence of $g$ is at most the number of edges in $g$. in this p...

Five theoretical and/or experimental problems involving benzenoid polycyclics and related eystems are discussed. The dualiet graph characterizes uniquely any polycyclic aromatic hydrocarbon (PAH or pol.yhex), and differentiates between catafusenes, perifusenes and coronafusenes (catahexes, perihexes, coronahexes). 1. The topology of catafusenes, expre8sed by their dualist graphs, can be correla...

The core issue of artificial intelligence is thinking simulation. We use the electrocardiogram (ECG) as an example. Here, Abstract and logical thinking work alongside with imagery thinking and experience analysis, and the physicians diagnosis has both macro precepts together with micro particulars. Meanwhile, a few problems restrict clinical acceptance of the many theoretical ECG analysis metho...
