Some consequences of singers' nodes

Some phonatory characteristics of singers and nonsingers

Using inverse filtering, voice source characteristics related to vocal £old adductory force, and the first formant frequency, are analyzed in six professional male singers and six male nonsingers repeatedly phonating the syllable /pae:/ in loud and soft phonation at different fundamental frequencies throughout the subjects' ranges. For each voice sample, inverse filtered air flow was recorded a...

Graph matching the matchable nodes when some nodes are unmatchable

We consider the problem of graph matchability in non-identically distributed networks. In a general class of edge-independent networks, we demonstrate that graph matchability is almost surely lost when matching the networks directly, and is almost perfectly recovered when first centering the networks using Universal Singular Value Thresholding before matching. These theoretical results are then...

Electrocardiogram: Some Practical Consequences

OKHAWA and his colleagues have provided histologic evidence that a lesion in the distal or branching portion of the His bundle, and thus actually within the ventricles, may produce complete atrioventricular (AV) block on the surface ECG associated with "AH" block on the His bundle electrogram (atrial impulses blocked proximal to the His deflection) and that this may be associated with an escape...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
