This editorial examines design techniques for high-speed serial data links over wire channels. The state-of-theart of serial links over wire channels is briefly studied. The imperfections of wire channels at high frequencies and their effect on multi-Gbps serial links are examined. It is followed with a close examination of modulation schemes effective in combating the effect of the finite bandwidth of wire channels. Channel equalization, both pre-emphasis and post-equalization, are investigated with an emphasis on adaptive decision feedback equalization. Challenges and opportunities in combating ISI are explored.

The recording of magnetic fields associated with cellular current flow in nerve and muscle fibers was first reported nearly three and a half decades ago. These magnetic fields are detected using a room-temperature toroidal pickup coil called the neuromagnetic current probe. These probes can be employed to measure action currents of biological tissues while they are resting in their own natural settings or in saline baths, thereby reducing the risk associated with elevating and drying the tissues in the air during experiments. These magnetic fields are relatively insensitive to muscle movement since these probes are not directly connected to the tissues, and distortions of the recorded data due to changes in the electrochemical interface between the probes and the tissues are minimal. In this paper, the magnetic fields of single nerve axons, muscle fibers and nerve bundles are discussed. Furthermore, one of the possible applications of the neuromagnetic current probe to the intraoperative assessment of damaged nerve bundles is discussed.

This review paper analyzes the role of natural and man-made magnetic and electromagnetic fields in origin and evolution of life as well as the effects of contemporary magnetic/electromagnetic fields on human life. Both, hazard and benefit of these fields is discussed with the review of variety of signals that affect human life. The emphasis is on the use of electromagnetic fields in medicine for diagnostics and therapy. The paper demonstrates basic science and clinical achievements in planning and executing studies and clinical trials, as well as the perspectives for future development of magnetotherapy.
