In some aspects, a processor may receive a starting point and an ending point from a runner. The method further provides for a main menu including functions selected from the group including an exit, a video, a portfolio view, a 3-Dimensional view, an interactive, an email, a sound onoff, or a statistics function. A back side of the connector has a width greater than a width of its front side so as to define an acute angle between the sidewalls. for correcting phase offsets of data streams transmitted over ultra long distances, the utilization of the subject phase shifter plays a part in obviating the necessity of having regeneration units every 70 to 100 miles, thus permitting error-free transmission over as many as 2500 miles without the requirement for regeneration. The invention also provides compositions and methods for use in treatment or modulation of bacterial biofilm and biofilm formation.
