Within the framework of equilibrium statistical mechanics the free energy of a phase gives a measure of its associated probabilistic weight. In order to determine phase boundaries one must then determine the conditions under which the free energy difference (FED) between two phases is zero. The underlying complexity usually rules out any analytical approaches to the problem, and one must theref...

Cervical ectopic pregnancy: ultrasound diagnosis and conservative management Gravidez ectópica cervical: diagnóstico ecográfico e tratamento conservador

Cervical ectopic pregnancy is a rare condition. We report a case of cervical ectopic pregnancy describing the ultrasound diagnosis and successful conservative management with methotrexate. Ultrasound findings and management options are discussed.

raditionally, the function of a network has been to deliver packets from one endpoint to another. There was a distinct boundary between what is done within the network and what is done by the users. Processing within the network was limited basically to routing, congestion control and quality of service (QoS) schemes. This kind of a network can be regarded as “passive”. Several problems with “p...
