There are many ethical and legal implications in a variety of activities in the neurosurgeon's day-to-day practice. Awareness of and proper attention to these issues are a professional responsibility that should be attended to, to ensure that the practice of medicine is carried out efficiently and effectively, to maintain public confidence, and to try to avoid micromanagement by third parties. The authors discuss four such subjects of particular interest to them, namely: 1) reporting of certain diseases and conditions to authorities and third parties; 2) acting without the consent of the patient to prevent harm to him or her and/or others; 3) reporting problems with drugs and devices; and 4) the detection and treatment of colleagues impaired by alcohol, drugs, or mental or physical illness.

This paper presents the methodology for redistribution layer (RDL) design of a communication Coherent Receiver block. The analysis focuses on the dualinput traces of the receiver for crosstalk mitigation between this block and a local aggressor. Interaction between Die/Package/Test-board is also discussed.Full-wave simulations show excellent correlation in electrical performance up to 6GHz. The measured trace-to-trace isolation for the integrated solution is reported to be close to -40dB at 2.7 GHz.
