چکیده
The use of pacemakers and central venous catheters (CVC) has become commonplace in the field of medicine.

متن کاملDistinguishing “crowded” Organizations from Groups and Communities: Is Three a Crowd?
In conventional wisdom on crowdsourcing, the number of people define the crowd and maximizing this number is often assumed to be the goal of any crowdsourcing exercise.
