INTRODUCTION The use of CEST contrast for pH mapping has been demonstrated for labile protons of amide and amine protons of creatine (Cr) (1, 2). Amide proton CEST contrast has been shown to decrease with decrease in pH with a rat brain stroke model. The pH in stroke region of the rat brain decreases with progression of stroke effect. Here we demonstrate the dependence of Glutamate amine proton...
Two \objects," which run under Max/MSP or Pd, do di erent kinds of real-time analysis of musical sounds. Fiddle is a monophonic or polyphonic maximum-likelihood pitch detector similar to Rabiner's, which can also be used to obtain a raw list of a signal's sinusoidal components. Bonk does a bounded-Q analysis of an incoming sound to detect onsets of percussion instruments in a way which outperfo...
Introduction Amide proton transfer (APT) imaging is an application of chemical exchange saturation transfer (CEST) imaging that generates contrast from exchangeable protons on the backbone of endogeneous mobile proteins and peptides. In a conventional APT experiment, a label image is acquired with RF irradiation of amide protons at 3.5ppm, and subtracted from a reference image with RF irradiati...
A method that utilizes a spectral flatness based tonality feature for segmentation and contentbased retrieval of audio is outlined. The method uses the tonality measure which is derived from the discrete bark spectrum as a means of detecting transitions between tonal and noise-like parts of the audio input. The meaning of ‘tonal’ in this context is different from the music-theoretical meaning a...
The successful remediation of Cr contaminated soils via chemical reduction and stabilization of soluble, toxic Cr(V1) species to insoluble Cr(II1) species relies on the long term leachability and reoxidation of reduced Cr compounds. Information of Cr chemical environments is invaluable for evaluating the efficiency of proposed stabilization technologies. We describe a matrix of Fe and Cr K-edge...
Background and Objective: Obesity is a low grade inflammatory condition. It seems that there is an association between diet quality and inflammatory markers. Healthy Eating Index (HEI) is one of the important tools to assess diet quality. In this study, we assessed the effect of improving HEI score through nutritional education on serum levels of inflammatory markers in obese women. Materials a...
We propose a new method for the detection of spectral lines in random noise. It mimics the processing scheme of matching filtering i.e., a whitening procedure combined with the measurement of the correlation between the data and a template. Thanks to the original noise spectrum estimate used in the whitening procedure, the algorithm can easily be tuned to the various types of noise. It can thus...
INTRODUCTION: Quantitative Susceptibility Mapping (QSM) aims to quantify tissue magnetic susceptibility with applications such as tissue contrast enhancement [1], venous blood oxygenation [2], and iron quantification [3]. The magnetic susceptibility χ maps to the observed phase shift via a well-understood transformation, but the inverse problem, i.e. estimation of χ from phase, is ill posed due...
Operational Modal Analysis, also known as Output Only Modal Analysis, has in the recent years, been used for determination of modal parameters of civil engineering structures and is now becoming widely used also for mechanical structures. The advantage of the method is that no artificial excitation needs to be applied to the structure, or force signals to be measured. In this paper, the non-par...
Design of a Health Information System Enhancing the Performance of Obesity Expert and Children Teams
The globally increasing prevalence of childhood obesity is one of the most serious public health challenges of the twenty-first century. Due to the need for multi-professional therapies that require a high amount of personnel and financial resources, IT-supported interventions promise help. So far, meta-studies show their limited impact on health outcomes. This work presents therefore a design ...
