Abstract: A medical catheter and a method for fabricating it are disclosed. The medical catheter includes a catheter body including a proximal section and a distal section sequentially arranged along an axis. Stiffness of the proximal section is greater than stiffness of the distal section. The distal section includes a transition section and a flexible section from a proximal end to a distal end thereof.

Abstract: Systems and method for determining a topic cohesion measurement between a content item and a hyperlinked landing page are presented. In one embodiment, a plurality of content item signals is generated for the content item and a corresponding plurality of signals are generated for the hyperlinked landing page. An analysis of the corresponding signals is conducted to determine a measurement of topic cohesion, a topic cohesion score, between the content item and the hyperlinked landing page.

Upon a determination that the topic cohesion score is less than a predetermined threshold, remedial actions are taken regarding the hyperlink of the content item. Alternatively, positive actions may be carried out, including promoting the content item to others, associating advertisements with the content item, and the like.
