Introduction: The problem of noise-free encoding for an open radio channel is of great importance for data transfer. The results presented in this paper are aimed at stimulating scientific interest in new codes and bases derived from quasi-orthogonal matrices, as a basis for the revision of signal processing algorithms.Purpose: Search for new code sequences as combinations of codes formed from the rows of Mersenne and Raghavarao quasi-orthogonal matrices, as well as complex and more efficient Barker — Mersenne — Raghavarao codes.Results: We studied nested code sequences derived from the rows of quasi-orthogonal cyclic matrices of Mersenne, Raghavarao and Hadamard, providing estimates for the characteristics of the autocorrelation function of nested Barker, Mersenne and Raghavarao codes, and their combinations: in particular, the ratio between the main peak and the maximum positive and negative “side lobes”. We have synthesized new codes, including nested ones, formed on the basis of quasi-orthogonal matrices with better characteristics than the known Barker codes and their nested constructions. The results are significant, as this research influences the establishment and development of methods for isolation, detection and processing of useful information. The results of the work have a long aftermath because new original code synthesis methods need to be studied, modified, generalized and expanded for new application fields.Practical relevance: The practical application of the obtained results guarantees an increase in accuracy of location systems, and detection of a useful signal in noisy background. In particular, these results can be used in radar systems with high distance resolution, when detecting physical objects, including hidden ones.

This chapter analyzes and recommends federal corporate governance enhancements that should be implemented. These enhancements, which should be adopted in a measured and directed manner, are necessary to remediate certain deficiencies that currently exist. Consistent therewith, this chapter focuses on several important matters that merit attention, including the undue deference by federal courts to state law, the appropriate application of federal law to tactics undertaken in tender offers, the need for a federal statute encompassing insider trading, and the propriety of more vigorous oversight by the Securities and Exchange Commission (such as with respect to the “current” disclosure regime, the SEC’s Standards of Professional Conduct for Attorneys, and the Commission’s neglecting at times to invoke its statutory resources). Thus, the analysis set forth in this chapter identifies significant deficiencies that currently exist and recommends measures that should be implemented on the federal level to enhance corporate governance standards.

Abstract Background Transitioning from an old medical coding system to a new one can be challenging, especially when the two coding systems are significantly different. The US experienced such a transition in 2015. Objective This research aims to introduce entropic measures to help users prepare for the migration to a new medical coding system by identifying and focusing preparation initiatives on clinical concepts with more likelihood of adoption challenges. Methods Two entropic measures of coding complexity are introduced. The first measure is a function of the variation in the alphabets of new codes. The second measure is based on the possible number of valid representations of an old code. Results A demonstration of how to implement the proposed techniques is carried out using the 2015 mappings between ICD-9-CM and ICD-10-CM/PCS. The significance of the resulting entropic measures is discussed in the context of clinical concepts that were likely to pose challenges regarding documentation, coding errors, and longitudinal data comparisons. Conclusion The proposed entropic techniques are suitable to assess the complexity between any two medical coding systems where mappings or crosswalks exist. The more the entropy, the more likelihood of adoption challenges. Users can utilize the suggested techniques as a guide to prioritize training efforts to improve documentation and increase the chances of accurate coding, code validity, and longitudinal data comparisons.

ABSTRACTThis is a discussion paper prepared by the Compliance/Peer Review Working Party of the Professional Affairs Board. It considers the monitoring of compliance with the professional conduct standard and guidance notes, how this is being done, and whether changes need to be made to the monitoring in the light of on-going changes to the regulation of financial services.
