This article describes three aspects of the author's early work on the evolution of the cooperation. First, it explains how the idea for a computer tournament for the iterated Prisoner's Dilemma was inspired by the artificial intelligence research on computer checkers and computer chess. Second, it shows how the vulnerability of simple reciprocity of misunderstanding or misimplementation can be...

The frequency response of multimode optical fibre (MMF) shows the existence of passbands in the higher frequency region above the -3dB baseband. By Subcarrier Multiplexing, these passbands can be used to accommodate a number of transmission channels for different services. In this way various groups of services may be integrated in a single MMF-based in-building or short-reach access infrastruc...

It is shown that a surface wave will be generated by a horizontal.slot situated above a corrugated or dielectric-coated guiding surface. A physical interpretation of the analysis is suggested which explains the mechanism of launching in terms of a resonance phenomenon allied to that which arises when a piston attenuator is terminated by a reactance equal and opposite to its own (reactive) chara...

Open radical prostatectomy remains the gold standard for management of organ-confined prostate cancer. However, recently there has been a trend toward the search and development of less invasive surgical options. Robotic-assisted laparoscopic prostatectomy (RALP) is rapidly becoming the most commonly performed surgical approach to treat these tumors. The most commonly used robot is the da Vinci...

Consider the following: Team members are hijacking team meetings and convincing others to deviate from the original goals. The team leader lacks the skills to recognize these dynamics. Furthermore, the leader struggles with determining a turnaround approach and leadership model to effectively regain control of this intense team and refocus the members to achieve the original goals and objective...
