The fatty acid compositions of the major cerebral cortex phospholipids, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine were measured in 16 term and one preterm 'cot death' infants fed exclusively either breast milk or one of two formulas. Docosahexaenoic acid (DHA; C22:6n-3) content in cerebral cortex phosphatidylethanolamine and phosphatidylserine of breast fed infants w...

In this paper, we introduce a novel approach to guide tile size selection by employing analytical models to limit empirical search within a subspace of the full search space. Two analytical models are used together: 1) an existing conservative model, based on the data footprint of a tile, which ignores intra-tile cache block replacement, and 2) an aggressive new model that assumes optimal cache...

Many classes of methods for noisy optimization problems are based on function information computed on sequences of simplices. The Nelder-Mead, multidirectional search, and implicit filtering methods are three such methods. The performance of these methods can be explained in terms of the difference approximation of the gradient implicit in the function evaluations. Insight can be gained into ch...

A general hill-climbing attack to biometric systems based on a modification of the downhill simplex algorithm is presented. The scores provided by the matcher are used in this approach to adapt iteratively an initial estimate of the attacked template to the specificities of the client being attacked. The proposed attack is evaluated on a competitive feature-based signature verification system o...

We begin by apologizing for the lamentable omission of Professor Nelder’s interesting and controversial papers both in Lencina, Singer and Stanek (2005) and in Lencina and Singer (2006). Although the focus of our papers is much narrower than that of his articles, we feel that any manuscript touching the topic of parametrization and definition of hypotheses in linear mixed models should necessar...

This paper proposes a new spectral transformation for speaker normalization. We use the Bilinear Transformation (BLT) to introduce a new frequency warping resulting from a mapping of a prototype Band-Pass (BP) filter into a general BP filter. This new transformation called “Band-Pass Transform” (BPT) offers two degrees of freedom enabling complex warpings of the frequency axis and different fro...

Wireless sensor networks (WSNs) have been of great interest among academia and industry due to their diverse applications in recent years. The main goal of a WSN is data collection. As the amount of the collected data increases, it would be essential to develop some techniques to analyze them. In this paper, we propose an in-network optimization algorithm based on Nelder-Mead simplex to increme...

The term ‘supply chain management’ has become common in the business world, which can be understood from the positive results of research in the area, particularly in supply chain optimization. Transportation is a frontier in achieving the objectives of the supply chain. Thrust is also given to optimization problems in transportation. The fixed-charge transportation problem is an extension of t...

Isotopic data reported by Mead, Steinberg, and Howton in 1953 (1) and by Steinberg, Slaton, Howton, and Mead in 1956 (2) firmly established the incorporation of acetate and of linoleate, respectively, into arachidonic acid in the rat. Witten and Holman in 1952 (3) had suggested that pyridoxine stimulated this conversion. They had shown that rats deficient in essential fatty acids and in pyridox...
