Cooperation is vital for maintaining the integrity of complex life forms. In many cases in nature cooperation manifests itself through constituent parts performing different, but complementary, functions. The vast majority of studies on the evolution of cooperation, however, look only at the special case in which cooperation manifests itself via the constituent parts performing identical tasks....

International cooperation is an integral part of furthering medical and scientific progress. Many specilist societies exist for that purpose and have written into their constitutions that such cooperation and coordination is their aim.

In this paper, we investigate the benefits and drawbacks of different approaches for solving a cooperative foraging task with two robots. We compare a classical clonal approach with an additional approach which favors the evolution of heterogeneous behaviors according to two defining criteria: the evolvability of the cooperative solution and the efficiency of the coordination behaviors evolved....

N-[1-(2-Phenylethyl)-piperidin-4-yl]-propionamide (fentanyl) is the prototype of the 4anilidopiperidine class of synthetic opioid analgesics. This study was aimed to review the best method of synthesis and to determine the Structure-Activity-Relationship (SAR) of fentanyl analogs. The best method of synthesis of fentanyl is the method described in International Application No.: PCT/IN2009/00015...

The absolute V light curves of 5 SNe Ia, selected to represent the known range of absolute luminosities at maximum for this class of objects, are presented. Comparison of the long term luminosity evolution shows that the differences seen at maximum persist, and actually increase with time, reinforcing the notion that intrinsic differences do exist among SNe Ia. Since such differences are not ac...
