Minimal and canonical rational generator matrices for convolutional codes
A full-rank IC x n matrix G(D) over the rational functions F(D) generates a rate R = k/n convolutional code C. G(D) is minimal if it can be realized with as few memory elements as any encoder for C, and G(D) is canonical if it has a minimal realization in controller canonical form. We show that G(D) is minimal if and only if for all rational input sequences p1 (D), the span of U (D) G (D) covers t

Dc-resistometric Urea Sensitive Device Utilizing A Conducting Polymer Film For the Gas-phase Detection of Ammonia
The construction of an urea sensitive device based on a conducting polymer is described. The conducting polymer (polypyrrole) was exposed only to a gas-phase; this led to a significant improvement in its stability. A DC-resistometric measuring principle was used, which required only simple measuring equipment. The device responded rapidly to between 0 and 500 mM urea, with resistance changes of be

An Improved Method for Automatic Segmentation of the Left Ventricle in Myocardial Perfusion SPECT.
This study describes and validates a new method for automatic segmentation of left ventricular mass (LVM) in myocardial perfusion SPECT (MPS) images. This is important for estimating the size of a perfusion defect as percentage of the left ventricle. METHODS: A total of 101 patients with known or suspected coronary artery disease underwent both rest and stress MPS and MRI. A new automated algorith
Autoionization Widths of the No Rydberg-valence State Complex In the 11-12 Ev Region
The photoion excitation spectra of (NO)-N-14 and (NO)-N-15 have been studied in the 105-112 Mn excitation region using high-order harmonic laser spectroscopy. Utilizing the small bandwidth offered by this technique, the natural widths of prominent lines in this region have been measured. These lines originate from interactions between high-lying Rydberg levels converging to the NO+ electronic grou
Plant nitrate use in deciduous woodland: the relationship between leaf N, N-15 natural abundance of forbs and soil N mineralisation
Our aim was to study whether the in situ natural abundance N-15 (delta(15)N)-values and N concentration of understory plants were correlated with the form and amount of mineral N available in the soil. Also to determine whether such differences were related to earlier demonstrations of differences in biomass increase in the same species exposed to nutrient solutions with both NO3- and NH4+ or to N
New Zr II oscillator strengths and the zirconium conflict in the HgMn star chi Lupi
Lifetimes on the sub-nanosecond scale for the levels v(2)D(3/2), v(2)F(3/2) and v(2)F(5/2) in the 4d5s5p configuration in Zr II have been measured, using the method of laser-induced fluorescence. Combined with branching fractions obtained with the Lund Ultraviolet (UV) Fourier Transform Spectrometer (FTS), experimental oscillator strengths have been derived. From Hubble Space Telescope/Goddard Hig
Radiative Lifetime Determination For the 3s4p (1)p(1) State of Magnesium Using Pulsed Level-crossing Spectroscopy
The natural radiative lifetime of the 3s 4p 1P1 level of neutral magnesium was measured by pulsed level-crossing spectroscopy at the short excitation wavelength of 202.6 nm. We obtained tau = 13.4(5) ns for this state, strongly deviating from a previous beam-foil result, but in good agreement with a multi-configuration Hartree-Fock calculation. A discussion of the applicability of the pulsed Hanle
Disturbed vibrotactile sense in finger pulps in patients with Type 1 diabetes-correlations with glycaemic level, clinical examination and electrophysiology.
Aims In a cohort of men and women with Type 1 diabetes, prospectively followed for > 20 years, vibrotactile sense in fingers was investigated and related to neurophysiological tests, glycaemic level and clinical score. Methods Out of 58 patients, diagnosed at the age of 15-25 years and recruited 1984-1985, 32 patients (13 women, median age 52 years, range 44-75 years; 19 men, median age 52 years,

Essays on Credit Risk
This dissertation covers the issues related to credit risk that stem from the recent financial crisis and that are concerned by investors, financial intermediaries, and governments. The results of the research have important implications for asset managers, such as using the information from the credit risk market to rebalance stock portfolios, and for policy makers in regulating or bailing out ba

Mchf Calculations For Atomic Properties
A historical review of the early development of Hartree-Fock and Multiconfiguration Hartree-Fock theories is presented. After the underlying theory is summarized, some recent results from the application of these methods to the prediction of atomic properties are described. These include total energies, transition probabilities, autoionization rates, specific mass shifts, and hyperfine parameters.
