BACKGROUND Radiofrequency is widely used in the treatment of chronic pain for its efficacy and low incidence of side effects and complications. Despite this, it is commonly believed that this kind of treatment could interfere with medical implantable devices. Potential interference between implanted devices such as pacemakers, defibrillators and spinal cord stimulators and the radiofrequency of...

The electromagnetic compatibility (EMC) community, usually concerned with noise and interference at the electronic-system level, has recently focused more attention on integrated circuits (ICs). This review concentrates upon the recent advances in microelectronics technology, the understanding of internal couplings within ICs, parasitic emission, and susceptibility to radiofrequency interferenc...

We present the case of a 52 year-old male with a history of C-hepatitis and two liver neoplastic lesions treated by radiofrequency (RF) ablation. The patient wears an abdominally-implanted unipolar VVI pacemaker that did not show any signs of interference during RF pulses. We describe the procedure performed and discuss the present knowledge regarding the possibilities of RF interference with t...

We experimentally investigate the outcoupling of atoms from Bose-Einstein condensates using two radiofrequency rf fields in the presence of gravity. We show that the fringe separation in the resulting interference pattern derives entirely from the energy difference between the two rf fields and not the gravitational potential difference between the two resonances. We subsequently demonstrate ho...

A common problem with radiofrequency (RF) receivers is that in addition to the desired signal, there is an interfering signal of much greater total power. These receivers can be for communications, radar, interception, etc. The interference can arise intentionally, such as from intentional jamming, or unintentionally, such as radiofrequency interference from a nearby transmitter. There is a nee...

A large body of evidence now indicates that the amount of mercury released from dental amalgam fillings can be significantly accelerated by exposure to radiofrequency electromagnetic fields (RF-EMFs) such as common mobile phones and magnetic resonance imaging (MRI). Studies performed on the increased microleakage of dental amalgam restorations after exposure to RF-EMFs have further supported th...

Recent models of hippocampal function emphasize its potential role in disambiguating sequences of events that compose distinct episodic memories. In this study, rats were trained to distinguish two overlapping sequences of odor choices. The capacity to disambiguate the sequences was measured by the critical odor choice after the overlapping elements of the sequences. When the sequences were pre...
