background according to world health organization (who) estimation, more than half of all pharmaceutical products are inappropriately prescribed, distributed, and sold and more than half of all patients use the medicines prescribed for them incorrectly. as more than 40% of therapeutic costs are pharmaceutical costs, this implies a significant waste of health resources in the world. objectives t...

When one surveys Professor Carbonell's many and varied research contributions, two more or less constant methodological trends seem to stand out. They are the preference for an integra-tive outlook and insistence on developing computational systems. The integrative outlook stresses the multiplicity of causes in behavior and contributing factors in reasoning. It is a rather difficult position to...

This article formalizes investor rationality and irrationality, exuberance and apprehension, to consider the implications of belief formation for the fragility of an economy’s financial structure.

In this paper we clarify and expand on our ideas, and respond to his assertion that medicine, ethics and atheism are objective, rational and true, while religion is irrational and false.

We construct a full data rate space–time (ST) block code over = 2 transmit antennas and = 2 symbol periods, and we prove that it achieves a transmit diversity of 2 over all constellations carved from [ ] . Further, we optimize the coding gain of the proposed code and then compare it to the Alamouti code. It is shown that the new code outperforms the Alamouti code at low and high signal-to-noise...
