The fast orthogonal search (FOS) algorithm has been shown to accurately model various types of time series by implicitly creating a specialized orthogonal basis set to fit the desired time series. When the data contain periodic components, FOS can find frequencies with a resolution greater than the discrete Fourier transform (DFT) algorithm. Frequencies with less than one period in the record length, called subharmonic frequencies, and frequencies between the bins of a DFT, can be resolved. This paper considers the resolution of subharmonic frequencies using the FOS algorithm. A new criterion for determining the number of non-noise terms in the model is introduced. This new criterion does not assume the first model term fitted is a dc component as did the previous stopping criterion. An iterative FOS algorithm called FOS first-term reselection (FOS-FTR), is introduced. FOS-FTR reduces the mean-square error of the sinusoidal model and selects the subharmonic frequencies more accurately than does the unmodified FOS algorithm.

Very low birth weight (VLBW) infants less than 1,000 g often experience hyperkalemia and hyperglycemia during the initial hospital course. Hyperkalemia has been noted in 44% to 50% of infants less than 800 g birth weight or less than 28 to 29 weeks' gestation. Hyperglycemia occurs 18 times more frequently in infants less than 1,000 g than in those weighing more than 2,000 g. Insulin has been used for VLBW infants less than 1,000 g to manage hyperkalemia, control hyperglycemia, and optimize parenteral nutrition. A protocol for using exogenous insulin therapy for VLBW infants is described.

The roles of clinical nurse specialist (CNS) neonatal nurse practitioner (NNP) have originated and evolved to meet specific needs in the nursing and medical community. The CNS role was developed in response to the perception that patient care needed to be improved; the NNP role resulted from an acute shortage of physicians to provide neonatal medical management. While on the surface these two roles may appear to be vastly different, many facets of each may be effectively interfaced. The NNP-CNS practice at Doernbecher Neonatal Care Center is an example of successful convergence of the two roles. The implementation of the combined practice is described in this article.

The reduction in the size of antennas for personal communication systems applications is a research area that is receiving lots of attention. The literature concentrates on reducing the size of microstrip patches however most of these antenna types require a large ground plane. Reducing the size of the ground plane has adverse affects on the antenna. To counter these affects a novel antenna type is presented. This antenna uses a shorted circular patch surrounded with nonplanar rings. These rings allow a reduction in the ground plane to a radius of less than 0.23 and improve its radiation characteristics. Through examination of the currents on the antenna, the principle of operation is explained based on a Yagi-Uda like array concept. Further theoretical and experimental examination confirms the above explanation.Index Terms-Loop antennas, microstrip antennas, size control.

Only recently have students of political theory begun to pay attention to Plato's Menexenus, and it deserves this closer study. In this article, it is argued that the dialogue is best read as Plato's at least quasi—serious critique of Pericle' famous Funeral Oration, and that a comparison of these two works leads to a paradoxical discovery. For by presenting Socrates in the Menexenus as a defender of a restrained and traditional politics against the bold imperialism of Pericles, Plato presents a figure who is hard to square with the dialectical critic of the city found in dialogues like the Apology. Whether there is nonetheless some thread tying Socrates' venture at political rhetoric to his signature form of philosophy is the deepest question posed by the Menexenus and one which offers new insight on Plato's complex view of the relation between politics and philosophy.
