We define a chi-squared statistic for p-dimensional data as follows. First, we transform the data to remove the correlations between the p variables. Then we discretize each variable into groups of equal size and compute the cell counts in the resulting p-way contingency table. Our statistic is just the usual chi-squared statistic for testing independence in a contingency table. Because the cel...

The potential performance of superscalar processors can be exploited only when processor is fed with sufficient instruction bandwidth. The front-end units, the Instruction Stream Buffer (ISB) and the fetcher, are the key elements for achieving this goal. Current ISBs could not support instruction streaming beyond a basic block. In x86 processors, the split-line instruction problem worsens this ...

The many functions that a eukaryotic cell carries out require that its geneticmaterial ismaintained, read and translated in a highly organized manner. Besides rapid reaction to external stimuli long-term differentiation and developmental programs need to be faithfully executed. The blueprint for these processes resideswithinDNA as inheritablematerial. However, the many differences in the biolog...

This work aimed at evaluating the performance of three different intensity-modulated radiotherapy (IMRT) treatment planning systems (TPSs)--KonRad, XiO and Prowess--for selected pediatric cases. For this study, 11 pediatric patients with different types of brain, orbit, head and neck cancer were selected. Clinical step-and-shoot IMRT treatment plans were designed for delivery on a Siemens ONCOR...

PURPOSE To report peri-operative fractionated high-dose-rate (HDR) brachytherapy with a 3D customized Freiburg flap applicator to treat locally recurrent Wilms' tumor, followed by immediate hyperthermic intraperitoneal chemotherapy for a 16-year-old with a second recurrence of nephroblastoma (Wilms' tumor). MATERIAL AND METHODS The tumor was excised and surgical bed was treated with fractiona...

We calculate structure functions at small x both under the assumption of a hard singularity (essentially, a power behaviour x −λ , λ positive, for x → 0) or that of a soft-Pomeron dominated behaviour, also called double scaling limit, for the singlet component. A full next to leading order (NLO) analysis is carried for the functions F2, F Glue and the longitudinal one FL in ep scattering, and f...

Our goal is to automatically learn a perceptually-optimal target cost function for a unit selection speech synthesiser. The approach we take here is to train a classifier on human perceptual judgements of synthetic speech. The output of the classifier is used to make a simple three-way distinction rather than to estimate a continuously-valued cost. In order to collect the necessary perceptual d...

In this paper, we present a new lossless text compression technique which utilizes syllable-based morphology of multi-syllabic languages. The proposed algorithm is designed to partition words into its syllables and then to produce their shorter bit representations for compression. The method has six main components namely source file, filtering unit, syllable unit, compression unit, dictionary ...

One of the key challenges of optimizing a unit selection voice is obtaining suitable target and join cost weights. In this paper we investigate several strategies to train these weights automatically. Two training algorithms are tested, which are based on an acoustic distance that approximates human perception: a modified version of the well-known linear regression training and an iterative alg...

INTRODUCTION Somatosensory evoked potential (SEP) recordings and continuous electroencephalography (EEG) are important tools with which to predict Glasgow Outcome Scale (GOS) scores. Their combined use may potentially allow for early detection of neurological impairment and more effective treatment of clinical deterioration. METHODS We followed up 68 selected comatose patients between 2007 an...
